or follow instructions of the supervisor of assessments, which are in
accordance with law, shall be guilty of a Class B misdemeanor. Any supervisor
of assessments who willfully gives directions which are not in accordance with
law is guilty of a Class B misdemeanor.

cards maintained by a township assessor, multi-township assessor, or chief
county assessment officer shall be public records, and shall be available for

Sec. 9-30. 
		Property records systems - Townships and multi-townships. 
		The
township or multi-township assessor may spend funds for the preparation,
establishment and maintenance of a detailed property record system which would
provide information useful to assessment officials.  The assessor also may
enter into contracts with persons, firms or corporations for the preparation
and establishment of the record system. The property record system shall
include up-to-date and complete  tax maps, ownership lists, valuation standards
and property record cards, including appraisals, for all or any part of the
property in the township or multi-township assessment district in accordance
with reasonable rules and procedures prescribed by the Department, but the
system and records shall not be considered to be assessments nor limit the
powers and duties of assessing officials. The record shall be available to all
assessing officials and to the public.

Sec. 9-35. 
		County tax maps - Supervisor of assessments. 
		Except as
provided in Section 5-1108 of the Counties Code, each supervisor of assessments
shall prepare and maintain, in accordance with rules and procedures prescribed
by the Department, tax maps and up-to-date lists of property owners' names and
addresses and property record cards for all of the property in the county, and
shall procure at regular intervals from the records maintained by the county
recorder information relating to transfers of property. The supervisor of
assessments shall not, however, duplicate the work of any full-time township
assessor or multi-township assessor who maintains up-to-date and complete tax
maps, ownership lists and property record cards in accordance with rules and
procedures prescribed by the Department. This shall not preclude
the maintenance of duplicate records in the supervisor of assessments' office.
This Section shall not prohibit the preparation and setting up of a property
record system (including appraisals) and property record cards as provided for
in other Acts, but such system and records shall not be considered to be
assessments nor limit the powers and duties of the assessors as provided by
this Code. Systems and records or copies of them set up under other Acts may be
maintained by the supervisor of assessments in his or her office. In preparing
the original tax maps, lists and property record cards, he or she shall consult
with the Department and the Department shall furnish to the officer such
supplies and equipment as may, in its judgment, be necessary to set up the
original set of maps, lists and records required by this Section.

Sec. 9-40. 
		County tax maps; County assessor. 
		In any county with less than
3,000,000 inhabitants which elects a county assessor under Section 3-45, the
county assessor shall, except as provided in Section 5-1108 of the Counties
Code, prepare and maintain tax maps, up-to-date lists of property owners' names
and addresses, and property record cards for all of the property in the county.
 Those documents shall be prepared and maintained in accordance with rules and
procedures prescribed by the Department.  The county assessor also shall
procure at regular intervals from the records maintained by the recorder
information relating to transfers of property. The county assessor shall not
duplicate the work of any fulltime township assessor who maintains up-to-date
and complete tax maps, ownership lists and property record cards in accordance
with rules and procedures prescribed by the Department, but this
shall not preclude the maintenance of duplicate copies of those records in
the county assessor's office. This Section does not prohibit
the preparation and setting up of a property record system (including
appraisals) and property record cards as provided for in other Acts, but the
system and records shall not be considered to be assessments nor limit the
powers and duties of the assessors under this Code. Systems and records or
copies of them set up under such other Acts may be maintained by the county
assessor in his or her office. In preparing the original tax maps, lists and
property record cards, the county assessor shall consult with the Department.
The Department shall furnish to that officer supplies and equipment as may, in
its judgment, be necessary to set up the original set of maps, lists and
records required by this Section.

(35 ILCS 200/9-45)
Sec. 9-45. Property index number system. The county clerk in counties of
3,000,000 or more inhabitants and, subject to the approval of the county board,
the chief county assessment officer or recorder, in counties of less than
3,000,000 inhabitants, may establish a property index number system under which
property may be listed for purposes of assessment, collection of taxes or
automation of the office of the recorder. The system may be adopted in addition
to, or instead of, the method of listing by legal description as provided in
Section 9-40. The system shall describe property by township, section,
block, and parcel or lot, and may cross-reference the street or post office
address, if any, and street code number, if any. The county clerk, county
treasurer, chief county assessment officer or recorder may establish and
maintain cross indexes of numbers assigned under the system with the complete
legal description of the properties to which the numbers relate. Index numbers
shall be assigned by the county clerk in counties of 3,000,000 or more
inhabitants, and, at the direction of the county board in counties with less
than 3,000,000 inhabitants, shall be assigned by the chief county assessment
officer or recorder. Tax maps of the county clerk, county treasurer or chief
county assessment officer shall carry those numbers. The indexes shall be open
to public inspection and be made available to the public.  Any property index
number system established prior to the effective date of this Code shall remain
valid. However, in counties with less than 3,000,000 inhabitants, the system
may be transferred to another authority upon the approval of the county board.
Any real property used for a power generating or automotive manufacturing
facility located within a county of less than 1,000,000 inhabitants, as to
which litigation with respect to its assessed valuation is pending or was
pending as of January 1, 1993, may be the subject of a real
property tax assessment settlement agreement among the taxpayer and taxing
districts in which it is situated.  In addition, any real property that is (i) used for natural gas extraction and fractionation or olefin and polymer manufacturing  and (ii) located within a county of less than 1,000,000 inhabitants may be the subject of a real
property tax assessment settlement agreement among the taxpayer and taxing
districts in which the property is situated if litigation is or was pending as to its assessed valuation as of January 1, 2003 or thereafter. Other appropriate authorities, which
may include county and State boards or officials, may also be parties to
such agreements.  Such agreements may include the assessment of the
facility or property for any years in dispute as well as for up to 10 years in the future.
Such agreements may provide for the settlement of issues relating to the
assessed value of the facility and may provide for related payments,
refunds, claims, credits against taxes and liabilities in respect to past
and future taxes of taxing districts, including any fund created under
Section 20-35 of this Act, all implementing the settlement
agreement.  Any such agreement may provide that parties thereto agree not to
challenge assessments as provided in the agreement.  An agreement entered
into on or after January 1, 1993 may provide for the classification of property
that is the subject of the agreement as real or personal during the term of the
agreement and thereafter.  It may also provide that taxing
districts agree to reimburse the taxpayer for amounts paid by the taxpayer
in respect to taxes for the real property which is the subject of the
agreement to the extent levied by those respective districts, over and
above amounts which would be due if the facility were to be assessed as
provided in the agreement.  Such reimbursement may be provided in the
agreement to be made by credit against taxes of the taxpayer.  No credits
shall be applied against taxes levied with respect to debt service or lease
payments of a taxing district.  No referendum approval or appropriation
shall be required for such an agreement or such credits and any such
obligation shall not constitute indebtedness of the taxing district for
purposes of any statutory limitation.  The county collector shall treat
credited amounts as if they had been received by the collector as taxes
paid by the taxpayer and as if remitted to the district.  A county
treasurer who is a party to such an agreement may agree to hold amounts
paid in escrow as provided in the agreement for possible use for paying
taxes until conditions of the agreement are met and then to apply these
amounts as provided in the agreement.  No such settlement agreement shall
be effective unless it shall have been approved by the court in which such
litigation is pending.  Any such agreement which has been entered into
prior to adoption of this amendatory Act of 1988 and which is contingent
upon enactment of authorizing legislation shall be binding and enforceable.

		Maps and plats. 
		The chief county assessment officer may make or
purchase maps and plats that will facilitate the business of his or her office.

Sec. 9-55. 
		Survey by owner. 
		When a property is divided into parcels so that
it cannot be described without describing it by metes and bounds, it is the
duty of the owner to have the land surveyed and platted into lots. The platting
shall be in accord with the Plat Act. The plat shall
be certified and recorded.  Any unit of local government responsible for
issuing building permits may require, by ordinance, that the plat be certified
and recorded before the building permit is
issued, unless a
subdivision plat is not required under subsection (b) of Section 1 of the Plat
Act.
The description of property, in accordance with the number and description in
the plat, shall be a valid description of the property described. However, no
plat of a subdivision, vacation or dedication of a tract of land shall be
approved by a city, incorporated town or village officer, nor shall any
recorder record a plat, unless a statement from the county clerk is endorsed
thereon showing that he or she finds no delinquent general taxes, unpaid
current general taxes, delinquent special assessments or unpaid current special
assessments against the tract of land. No officer of a city, village or
incorporated town shall approve the plat of a subdivision of a tract of land
until all deferred installments of outstanding unpaid special assessments are
either certified as paid by the proper collector, or a division thereof is made
in accord with the proposed subdivision and duly approved by the court that
confirmed the special assessment.

otherwise provided by Section 10-30
with respect to assessments made in counties with less than
3,000,000 inhabitants, whenever acreage property has been
subdivided into lots
and the subdivision has been recorded, the lots shall be reassessed and placed upon
the assessor's books, replacing the acreage
property, as of the first day
of January immediately following the date of the recording or
filing of the subdivision.

		Revisions of assessments; Counties of less than 3,000,000. 
		The
chief county assessment officer of any county with less than 3,000,000
inhabitants, or the township or multi-township assessor of any township in that
county, may in any year revise and correct an assessment as appears to be just.
Notice of the revision shall be given in the manner provided in Section 12-10
and 12-30 to the taxpayer whose assessment has been changed.
(Source: P.A. 81-838; 88-455.)
(35 ILCS 200/9-80)
Sec. 9-80. Authority to revise assessments; Counties of less than 3,000,000. The chief county assessment officer in counties with less than 3,000,000
inhabitants shall have the same authority as the township or multi-township
assessor to assess and to make changes or alterations in the assessment of
property, and shall assess and make such changes or alterations in the
assessment of property as though originally made. Changes by the chief county
assessment officer in valuations shall be noted in a column provided, and no
change shall be made in the original assessor's figures.
When the chief county assessment officer or his or her deputy views property
for the purposes of assessing the property or determining whether a change or
alteration in the assessment of the property is required, he or she shall give
notice to the township assessor by U.S. Mail at least 5 days but not more than
30 days prior to the viewing, so that the assessor may arrange to be present at
the viewing, except if the township or multi-township assessor fails to timely return the assessment books or workbooks as required by Section 9-230.  He or she shall also give notice to owners of the properties by
means of notices in a paper of general circulation in the township.  The
notices shall state the chief county assessment officer's intention to view the
property but need not specify the date and time of the viewing. When the chief
county assessment officer or his or her deputy is present at the property to be
viewed, immediately prior to the viewing, he or she shall make a reasonable
effort to ascertain if the owner or his or her representative, or the assessor,
are on the premises and to inform them of his or her intention to view the
property.  Failure to provide notice to the township assessor and owner shall
not of and by itself invalidate any change in an assessment.  A viewing under
this Section and Section 9-155 means actual viewing of the visible property in
its entirety from, on or at the site of the property.
All changes and alterations in the assessment of property shall be subject to
revision by the board of review in the same manner that original assessments
are reviewed.

(35 ILCS 200/9-85)
Sec. 9-85. 
		Revision of assessments by county assessor and board of
review;
counties of 3,000,000
or more.  In counties with 3,000,000 or more inhabitants, the county assessor
shall have authority annually to revise the assessment books and correct them
as appears to be just; and on complaint in writing in proper form by any
taxpayer, and after affording the taxpayer an opportunity to be heard thereon,
he or she shall do so at any time, until the assessment is verified. An entry
upon the assessment books does not constitute an assessment until the
assessment is verified. When a notice is to be mailed under Section 12-55 and
the address that appears on the assessor's records is the address of a mortgage
lender or the trustee, where title to the property is held in a land trust, or
in any event whenever the notice is mailed by the assessor to a taxpayer at or
in care of the address of a mortgage lender or a trustee where the title to the
property is held in a land trust, the mortgage lender or the trustee within 15
days of the mortgage lender's or the trustee's receipt of such notice shall
mail a copy of the notice to each mortgagor of the property referred to in the
notice at the last known address of each mortgagor as shown on the records of
the mortgage lender, or to each beneficiary as shown on the records of the
trustee.
All changes and alterations pursuant to Section 16-95 or Section 16-120 in
the assessment
of
property shall be subject
to
revision and entry into the assessment books by the board of appeals (until
the first Monday in December 1998 and the board of review beginning the
first Monday in December 1998 and thereafter) in the same manner
as the original assessments.

times and in the manner provided in Sections 9-215 through 9-225, and also in
any year that the Department orders a reassessment (to the extent the
reassessment is so ordered), with reference to the amount owned on January 1 in
the year for which it is assessed, including all property purchased that day.
The assessment, as modified or equalized or changed as provided by law, shall
be the assessment upon which taxes shall be levied and extended during the
general assessment period for which the assessment is made, or during
the remainder of that general assessment period for any property reassessed
by order of the Department. No assessment shall be considered illegal by reason
of not having been listed or assessed in the name of the owner or owners.

		Assessment list; Delivery of books. 
		Before January 1 in each
year of the general assessment, as provided in Sections 9-215 through 9-225,
each county clerk shall make up the list of property to be assessed for taxes
for the townships or taxing districts in the county, in books for that purpose.
Annually, before January 1, he or she shall make up lists of properties which
are taxable, or which become taxable for the first time, and which are not
already listed, and make up lists of properties which have been subdivided and
not listed by the proper description. The county clerk shall enter in the
proper column, opposite the respective parcels, the name of the owner, or other
such persons, so far as he is able to ascertain the names. The lists shall
contain columns to show the number of acres or lots improved, and the assessed
value; the assessed value of improvements; the total value; and other
information as may be required. The county clerk shall also have prepared and
ready for delivery all blanks necessary in the assessment of property, and
shall deliver those blanks to the assessors along with the assessment books or
lists. The books or lists may be completed and delivered by townships or taxing
districts without waiting for the completion of all the books or lists, but all
assessment books or lists shall be delivered by the county clerk to the chief
county assessment officer on or before January 1.  The books or lists shall be
made in duplicate.

made up by congressional townships, but parts or fractional townships may be
added to full townships, at the discretion of the county board. In counties
under township organization, the books shall be made to correspond with the
organized townships. Separate books shall be made for the assessment of
property and the collection of all taxes and special assessments thereon,
within the corporate limits of cities, incorporated towns and villages, if
ordered by the county board.

which to enter railroad property as listed for taxation, and shall enter the
valuations assessed, corrected and equalized in the manner provided by law.
The county clerk shall extend all the taxes for which the property is liable
against its equalized assessed value. At the time fixed by law for delivering
tax books to the county collector, the clerk shall attach a warrant, under his
or her seal of office, and deliver the book to the county collector. The county
collector shall collect the taxes charged against railroad property, and pay
over and account for the taxes in the manner provided in other cases. The book
shall be returned by the collector and filed in the office of the county clerk.
The taxes on all railroad property shall be extended as on other property, and
shall be subject to the same penalties, dates of payment and methods of
enforcement as other property taxes.

may, and shall, at the request of the owner or his or her agent, be listed as
one tract, and when all lots in the same block belong to the same owner they
may, and shall, at the request of the owner or his or her agent, be listed as a
block. When several adjoining lots in the same block belong to the same owner,
they may, and shall, at the request of the owner or his or her agent, be
included in one description. However, this Section shall not apply to property
on which delinquent or forfeited taxes are outstanding.

		If the assessor or chief county
assessment officer finds that any property subject to taxation, or special
assessment, has not been returned to him or her by the clerk, or has not been
described in the subdivisions or manner required by this Code, he or she shall
correct the return of the clerk, and shall list and assess the property in the
manner required by law.
The assessor or chief county assessment officer shall, also, from time to
time, make alterations in the description of property as he or she may find
necessary. When property has been subdivided since the making of the general
assessment, the assessor or chief county assessment officer shall from time to
time correct the descriptions so that they correspond to the subdivision, and
distribute the assessment in the proper proportions among the parcels into
which the land has been subdivided; and in case of a vacation of a subdivision

		Valuation in years other than general assessment years. 
		On or
before June 1 in each year other than the general assessment year, in all
counties with less than 3,000,000 inhabitants, and as soon as he or she
reasonably can in counties with 3,000,000 or more inhabitants, the assessor
shall list and assess all property which becomes taxable and which is not upon
the general assessment, and also make and return a list of all new or added
buildings, structures or other improvements of any kind, the value of which had
not been previously added to or included in the valuation of the property on
which such improvements have been made, specifying the property on which each
of the improvements has been made, the kind of improvement and the value which,
in his or her opinion, has been added to the property by the improvements.  The
assessment shall also include or exclude, on a proportionate basis in
accordance with the provisions of Section 9-180, all new or
added buildings, structures or other improvements, the value of which was
not included in the valuation of the property for that year, and all
improvements which were destroyed or removed. In case of the destruction or
injury by fire, flood, cyclone, storm or otherwise, or removal of any
structures of any kind, or of the destruction of or any injury to orchard
timber, ornamental trees or groves, the value of which has been included in any
former valuation of the property, the assessor shall determine as near as
practicable how much the value of the property has been diminished, and make
return thereof.
Beginning January 1, 1996, the authority within a unit of local government
that is responsible for issuing building or occupancy permits shall notify the
chief county assessment officer, by December 31 of the assessment year, when a
full or partial occupancy permit has
been issued for a
parcel of real property. The chief county assessment officer shall
include in the assessment of the property for the current year the
proportionate value of new or added improvements on that property from the date
the occupancy permit was issued or from the date the new or added
improvement was
inhabitable and fit for occupancy or for intended customary use until December 31 of that year. If the chief county
assessment officer has already certified the books for the year, the board of
review or interim board of review shall assess the new or added improvements on
a proportionate basis for the year in which the occupancy permit was issued or the new or added
improvement was
inhabitable and fit for occupancy or for intended customary use.
 The proportionate value of
the
new or added improvements may be assessed by the board of review
or interim
board of review as omitted property pursuant to Sections 9-265, 9-270, 16-50
and 16-140 in a subsequent year on a proportionate basis for the year in which
the occupancy permit was
issued or the new or added improvement was
inhabitable and fit for occupancy or for intended customary use
if it was not assessed in that year.

		The owner of property on January 1 also shall be liable, on a proportionate
basis, for the increased taxes occasioned by the construction of new or added
buildings, structures or other improvements on the property from the date when
the occupancy permit was issued or from the date the new or added
improvement was inhabitable and fit for occupancy or for
intended customary use to December 31 of that year. The owner of the improved property shall
notify the assessor, within 30 days of the issuance of an occupancy permit
or within 30 days of completion of the improvements, on a
form prescribed by that official, and request that the property be reassessed.
The notice shall be sent by certified mail, return receipt requested and shall
include the legal description of the property.
When, during the previous calendar year, any buildings,
structures or other improvements on the property were destroyed and
rendered uninhabitable or otherwise unfit for occupancy or for customary
use by accidental means (excluding destruction resulting from the willful
misconduct of the owner of such property), the owner of the property
on January 1 shall be entitled, on a proportionate basis, to a diminution
of assessed valuation for such period during which the improvements were
uninhabitable or unfit for occupancy or for customary use. The owner of
property entitled to a diminution of assessed valuation shall, on a form
prescribed by the assessor, within 90 days after the destruction of any
improvements or, in counties with less than 3,000,000 inhabitants within 90
days after the township or multi-township assessor has mailed the application
form as required by Section 9-190, file with the assessor for the decrease of
assessed valuation. Upon failure so to do within the 90 day period, no
diminution of assessed valuation shall be attributable to the property.
Computations under this Section shall be on the basis of a year of 365 days.

		Change in use or ownership. 
		The purchaser of
property on January 1 shall be considered as the
owner on that day. However, when a fee
simple title or
lesser interest in property is purchased, granted, taken or otherwise
transferred for a use exempt from taxation under this Code, that property
shall be exempt from taxes from the date of the right of possession,
except that property acquired by condemnation is exempt as of the date the
condemnation petition is filed.
Whenever a fee simple title or
lesser interest in property is purchased, granted, taken or otherwise
transferred from a use exempt from taxation under this Code to a
use not so exempt, that property shall be subject to taxation from the date
of purchase or conveyance.  It shall be the obligation of the titleholder of
record in such cases where there is a change in use or a change in a
leasehold estate or, in cases where there has been a purchase, grant,
taking or transfer, it is the obligation of the transferee to notify the
chief county assessment officer within 30 days of that
action.  Failure to give the notification, resulting in the assessing
official continuing to list the property as exempt in subsequent years,
shall cause the property to be considered omitted property for the purpose
of this Code.  In those cases the county collector is authorized to issue a
tax bill to the person holding title to the property in that part of the
year during which it was not exempt from taxation for that part of
the year and to accept payment of the bill as full and final settlement of
tax liability for the year involved.

shall send to the owner by certified mail an application form for reduction of
the assessed valuation of that property as provided in Section 9-180.
(b) Whenever an official, employee, or other representative of a municipal
fire department, fire protection district, volunteer fire
protection association, or emergency services and disaster agency of a
political subdivision of this State is required by law to make an official
report to another government official or agency concerning a natural
disaster or accident that is likely to cause real property to have a diminished
assessed valuation, that official, employee, or representative shall
make a copy of the report available to the property owner on the owner's
request and shall insure that the report contains the following notice:
NOTICE TO PROPERTY OWNER
If your property has been damaged you may be eligible     for a decrease in the assessed valuation of your property, which could result in lower property taxes.  Contact your local assessor for more information.
(c) Regardless of whether an official report concerning the natural disaster
or accident is issued under subsection (b), the property owner may notify the
township assessor of the property's destruction, uninhabitability, or unfitness
for occupancy or normal use.

less than 3,000,000 inhabitants shall act as an equalizing authority for each
county in which he or she serves.  The officer shall examine the assessments in
the county and shall equalize the assessments by increasing or reducing the
entire assessment of property in the county or any area therein or of any class
of property, so that the assessments will be at 33 1/3% of fair cash value. The
equalization process and analysis described in this Section shall apply to all
property except farm and coal properties assessed under Sections 10-110 through

estimated 33 1/3% of the fair cash value of the property and
the assessed valuations at which the property is listed for each township,
multi-township or assessment district.  To make this analysis, he or she shall
use property transfers, property appraisals, and other means as he or she deems
proper and reasonable.
With the ratio determined for each township or assessment district,
the supervisor of assessments shall then determine the percentage to be
added to or deducted from the aggregate assessments in each township or
assessment district, other than property assessed under Sections 10-110 through

served by the chief county assessment officer. The assessment officer shall
then change the assessment of each parcel of property by application of the
equalization factor.

		Omitted property
(35 ILCS 200/9-260)
Sec. 9-260. Assessment of omitted property; counties of 3,000,000 or
more.
(a) After signing the affidavit, the county assessor
shall have power, when directed by the board of
appeals
(until the first Monday in December 1998 and the board of review
beginning
the first Monday in December 1998 and thereafter), or on his or her own
initiative, subject to the limitations of Sections 9-265 and 9-270, to assess properties which
may have been omitted from assessments
for the current year and not more than 3 years prior to the current year for which the property was
liable to be taxed, and for which the tax has not been paid, but only on notice
and an opportunity to be heard in the manner and form required by law, and
shall enter the assessments upon the assessment books. Any notice shall include (i) a request that a person receiving the notice who is not the current taxpayer contact the office of the county assessor and explain that the person is not the current taxpayer, which contact may be made on the telephone, in writing, or in person upon receipt of the notice, and (ii) the name, address, and telephone number of the appropriate personnel in the office of the county assessor to whom the response should be made. Any time period for the review of an omitted assessment included in the notice shall be consistent with the time period established by the assessor in accordance with subsection (a) of Section 12-55.  No charge for tax of
previous years shall be made against any property if (1) the assessor failed to notify the board of review of the omitted assessment in accordance with subsection (a-1) of this Section; (2) the property was last
assessed as unimproved, the owner of such property gave notice of
subsequent improvements and requested a reassessment as required by Section
9-180, and reassessment of the property was not made within the 16-month 
period immediately following the receipt of that notice; (3) the owner of the property gave notice as required by Section 9-265; (4) the assessor received a building permit for the property evidencing
that new construction had occurred or was occurring on the property but
failed to list the improvement on the tax rolls; (5) the assessor
received a plat map, plat of survey, ALTA survey, mortgage survey, or
other similar document containing the omitted property but failed to
list the improvement on the tax rolls; (6) the assessor received a real
estate transfer declaration indicating a sale from an exempt property
owner to a non-exempt property owner but failed to list the property on
the tax rolls; or (7) the property was the subject of an assessment
appeal before the assessor or the board of review that had included the
intended omitted property as part of the assessment appeal and provided
evidence of its market value.
(a-1) After providing notice and an opportunity to be heard as
required by subsection (a) of this Section, the assessor shall render a
decision on the omitted assessment, whether or not the omitted
assessment was contested, and shall mail a notice of the decision to the
taxpayer of record or to the party that contested the omitted assessment. The notice of decision shall contain a statement that the
decision may be appealed to the board of review. The decision and all
evidence used in the decision shall be transmitted by the assessor to
the board of review on or before the dates specified in accordance with
Section 16-110.
(b) Any taxes based on the omitted assessment of a property pursuant to
Sections
9-260 through 9-270 and Sections 16-135 and 16-140 shall be prepared and mailed at the same time as the
estimated first
installment property tax bill for the preceding year (as described in
Section 21-30)
is prepared and mailed. The omitted assessment tax bill
is not due
until the date on which the second installment property tax bill for the
preceding
year becomes due. The omitted assessment tax bill shall be deemed
delinquent
and shall bear interest beginning on the day after the due date of the second
installment
(as described in Section 21-25). In counties with 3,000,000 or more inhabitants, any taxes for omitted assessments for a tax year before tax year 2023 that are deemed
delinquent
after the due date of the second installment tax bill shall bear
interest at the rate of
1.5% per month, or portion thereof, until paid or forfeited (as described in
Section 21-25). In counties with 3,000,000 or more inhabitants,  any taxes for omitted assessments for tax year 2023 or thereafter that are deemed delinquent after the due date of the second installment tax bill shall bear interest at the rate of 0.75% per month, or portion thereof, until paid or forfeited (as described in Section 21-25).
(c) The
assessor shall have no power to change the assessment or alter the
assessment books in any other manner or for any other purpose so as to
change or affect the taxes in that year, except as ordered by the board of
appeals (until the first Monday in December 1998 and the board of review
beginning the first Monday in December 1998 and thereafter).  The county
assessor shall make
all changes and corrections ordered by the board of appeals
(until the first Monday in December 1998 and the board of review
beginning
the first Monday in December 1998 and thereafter).
The county assessor may for the purpose
of revision by the board of appeals
(until the first Monday in December 1998 and the board of review
beginning
the first Monday in December 1998 and thereafter)
certify the assessment books
for any town or taxing district after or when such books are completed.

(35 ILCS 200/9-265)
Sec. 9-265. Omitted property; interest; change in exempt use or ownership.
(a)
If any property is omitted in the assessment of any year or years, not to exceed the current assessment year and 3 prior years, so that the
taxes, for which the property was liable, have not been paid, or if by reason
of defective description or assessment, taxes on any property for any year or
years have not been paid, or if any taxes are refunded under subsection (b) of
Section 14-5 because the taxes were assessed in the wrong person's name, the
property, when discovered, shall be listed and assessed by the board of review
or, in counties with 3,000,000 or more inhabitants, by the county assessor
either on his
or her own initiative or when so directed by the board of appeals or board of
review.
(b) The
board of review in counties with less than 3,000,000 inhabitants or the
county assessor in counties with 3,000,000 or more inhabitants may
develop reasonable procedures for contesting the listing of omitted
property under this Division.
(c) For purposes
of this Section, "defective description or assessment" includes a description
or assessment which omits all the improvements thereon as a result of which
part of the taxes on the total value of the property as improved remain unpaid.
In the case of property subject to assessment by the Department, the property
shall be listed and assessed by the Department. All such property shall be
placed on the assessment and tax books.
(d) The arrearages of taxes which might
have been assessed, with 10% interest thereon for each year or portion thereof
from 2 years after the time the first correct tax bill ought to have been
received, shall be charged against the property by the county clerk.
(e) When property or acreage omitted by either incorrect survey or other
ministerial assessor error is discovered and the owner has paid its tax
bills as received for the year or years of omission of the parcel, then the
interest authorized by this Section shall not be chargeable to the owner.
However, nothing in this Section shall prevent the collection of the principal
amount of back taxes due and owing.
(f) If any property listed as exempt by the chief county assessment officer
has a change in use, a change in leasehold estate, or a change in titleholder
of record by purchase, grant, taking or transfer, it shall be the obligation
of the transferee to notify the chief county assessment officer in writing
within 90 days of the change. If mailed, the notice shall be sent by certified mail,
return receipt requested, and shall include the name and address of the
taxpayer, the legal description of the property, and the property index number
of the property when an index number exists. If notice is provided in person, it shall be provided on a form prescribed
by the chief county assessment officer, and the chief county assessment
officer shall provide a date stamped copy of the notice. Except as
provided in item (6) of subsection (a) of Section 9-260, item (6) of
Section 16-135, and item (6) of Section 16-140 of this Code, if the failure to give the
notification results in the assessing official continuing to list the property
as exempt in subsequent years, the property shall be considered omitted
property for purposes of this Code.
(g)   In counties with fewer than 3,000,000 inhabitants, if a
chief county assessment officer discovers at any time before
judgment that a property has been granted a homestead exemption
under Article 15 of this Code to which it was not entitled,
the chief county assessment officer may consider the erroneously
exempt portion of the property as omitted property under this
Section for that taxable year only.

Sec. 9-270. Omitted property; limitations on assessment. A charge for tax
and interest for previous years, as
provided in Sections 9-265 or 14-40, shall not be made
against any property for years prior to the date of ownership of the person
owning
the property at the time the liability for the
omitted tax was first
ascertained. Ownership as used in this section shall be held to refer to
bona fide legal and equitable titles or interests acquired for value and
without notice of the tax, as may appear by deed, deed of trust, mortgage,
certificate of purchase or sale, or other form of contract. No charge
for tax of previous years, as provided in Section 9-265,
shall be made against any property if (1) the assessor failed to notify the board of
review of an omitted assessment in accordance with subsection (a-1) of Section 9-260; (2) the property was
last
assessed as unimproved, the owner of the property gave notice
of
subsequent improvements and requested a reassessment as required by Section
9-180, and reassessment of the property
was not made
within the 16 month period immediately following the receipt of that
notice; (3) the owner of the property gave notice as
required by Section 9-265; (4) the assessor received a building permit
for the property evidencing that new construction had occurred or was
occurring on the property but failed to list the improvement on the tax
rolls; (5) the assessor received a plat map, plat of survey, ALTA
survey, mortgage survey, or other similar document containing the omitted
property but failed to list the improvement on the tax rolls; (6) the
assessor received a real estate transfer declaration indicating a sale
from an exempt property owner to a non-exempt property owner but failed
to list the property on the tax rolls; or (7) the property was the
subject of an assessment appeal before the assessor or the board of
review that had included the intended omitted property as part of the
assessment appeal and provided evidence of its market value. The owner of property, if known, assessed under this and the
preceding section shall be notified by the county assessor, board of
review or
Department, as the case may require.

(35 ILCS 200/9-275)
Sec. 9-275. Erroneous homestead exemptions.
(a)  For purposes of this Section:
"Erroneous homestead exemption" means a  homestead exemption that was granted for real property in a taxable year if the property was not eligible for that exemption in that taxable year.  If the taxpayer receives an erroneous homestead exemption under a single Section of this Code for the same property in multiple years, that exemption is considered a single erroneous homestead exemption for purposes of this Section. However, if the taxpayer receives erroneous homestead exemptions under multiple Sections of this Code for the same property, or if the taxpayer receives erroneous homestead exemptions under the same Section of this Code for multiple properties, then each of those exemptions is considered a separate erroneous homestead exemption for purposes of this Section.
"Homestead exemption" means an exemption under Section 15-165 (veterans with disabilities), 15-167 (returning veterans), 15-168 (persons with disabilities), 15-169 (standard homestead for veterans with disabilities), 15-170 (senior citizens), 15-172 (low-income senior citizens assessment freeze), 15-175 (general homestead), 15-176 (alternative general homestead), or 15-177 (long-time occupant).
"Erroneous exemption principal amount" means the total difference between the property taxes actually billed to a property index number and the amount of property taxes that would have been billed but for the erroneous exemption or exemptions.
"Taxpayer" means the property owner or leasehold owner that erroneously received a homestead exemption upon property.
(b)  Notwithstanding any other provision of law, in counties with 3,000,000 or more inhabitants, the chief county assessment officer shall include the following information with each assessment notice sent in a general assessment year:  (1)  a list of each homestead exemption available under Article 15 of this Code and a description of the eligibility criteria for that exemption, including the number of assessment years of automatic renewal remaining on a current senior citizens homestead exemption if such an exemption has been applied to the property; (2)  a list of each homestead exemption applied to the property in the current assessment year; (3)  information regarding penalties and interest that may be incurred under this Section if the taxpayer received an erroneous  homestead exemption in a previous taxable year; and (4)  notice of the 60-day grace period available under this subsection.  If, within 60 days after receiving his or her assessment notice, the taxpayer notifies the chief county assessment officer that he or she received an erroneous  homestead exemption in a previous taxable year, and if the taxpayer pays the erroneous exemption principal amount, plus interest as provided in subsection (f), then the taxpayer shall not be liable for the penalties provided in subsection (f) with respect to that exemption.
(c) In counties with 3,000,000 or more inhabitants, when the chief county assessment officer determines that one or more erroneous homestead exemptions was applied to the property, the erroneous exemption principal amount, together with all applicable interest and penalties as provided in subsections (f) and (j), shall constitute a lien in the name of the People of Cook County on the property receiving the erroneous homestead exemption.  Upon becoming aware of the existence of one or more erroneous homestead exemptions, the chief county assessment officer shall cause to be served, by both regular mail and certified mail, a notice of discovery as set forth in subsection (c-5). The chief county assessment officer in a county with 3,000,000 or more inhabitants may cause a lien to be recorded against property that (1) is located in the county and (2) received one or more erroneous homestead exemptions if, upon determination of the chief county assessment officer, the taxpayer received: (A) one or 2 erroneous homestead exemptions for real property, including at least one erroneous homestead exemption granted for the property against which the lien is sought, during any of the 3 collection years immediately prior to the current collection year in which the notice of discovery is served; or (B) 3 or more erroneous homestead exemptions for real property, including at least one erroneous homestead exemption granted for the property against which the lien is sought, during any of the 6 collection years immediately prior to the current collection year in which the notice of discovery is served.  Prior to recording the lien against the property, the chief county assessment officer shall cause to be served, by both regular mail and certified mail, return receipt requested, on the person to whom the most recent tax bill was mailed and the owner of record, a notice of intent to record a lien against the property. The chief county assessment officer shall cause the notice of intent to record a lien to be served within 3 years from the date on which the notice of discovery was served.
(c-5) The notice of discovery described in subsection (c) shall: (1) identify, by property index number, the property for which the chief county assessment officer has knowledge indicating the existence of an erroneous homestead exemption; (2) set forth the taxpayer's liability for principal, interest, penalties, and administrative costs including, but not limited to, recording fees described in subsection (f); (3) inform the taxpayer that he or she will be served with a notice of intent to record a lien within 3 years from the date of service of the notice of discovery; (4) inform the taxpayer that he or she may pay the outstanding amount, plus interest, penalties, and administrative costs at any time prior to being served with the notice of intent to record a lien or within 30 days after the notice of intent to record a lien is served; and (5) inform the taxpayer that, if the taxpayer provided notice to the chief county assessment officer as provided in subsection (d-1) of Section 15-175 of this Code, upon submission by the taxpayer of evidence of timely notice and receipt thereof by the chief county assessment officer, the chief county assessment officer will  withdraw the notice of discovery and reissue a notice of discovery in compliance with this Section in which the taxpayer is not liable for interest and penalties for the current tax year in which the notice was received.
For the purposes of this subsection (c-5):
"Collection year" means the year in which the first and second installment of the current tax year is billed.
"Current tax year" means the year prior to the collection year.
(d)  The notice of intent to record a lien described in subsection (c) shall: (1)  identify, by property index number, the property against which the lien is being sought; (2) identify each specific homestead exemption that was erroneously granted and the year or years in which each exemption was granted; (3)  set forth the erroneous exemption principal amount due and the interest amount and any penalty and administrative costs due; (4)  inform the taxpayer that he or she may request a hearing within 30 days after service and may appeal the hearing officer's ruling to the circuit court; (5)  inform the taxpayer that he or she may pay the erroneous exemption principal amount, plus interest and  penalties, within 30 days after service; and (6)  inform the taxpayer that, if the lien is recorded against the property, the amount of the lien will be adjusted to include the applicable recording fee and that fees for recording a release of the lien shall be incurred by the taxpayer. A lien shall not be filed pursuant to this Section if the taxpayer pays the erroneous exemption principal amount, plus penalties and interest, within 30 days of service of the notice of intent to record a lien.
(e)  The notice of intent to record a lien shall also include a form that the taxpayer may return to the chief county assessment officer to request a hearing.  The taxpayer may request a hearing by returning the form within 30 days after service.  The hearing shall be held within 90 days after the taxpayer is served.  The chief county assessment officer shall promulgate rules of service and procedure for the hearing.  The chief county assessment officer must generally follow rules of evidence and practices that prevail in the county circuit courts, but, because of the nature of these proceedings, the chief county assessment officer is not bound by those rules in all particulars.  The chief county assessment officer shall appoint a hearing officer to oversee the hearing.  The taxpayer shall be allowed to present evidence to the hearing officer at the hearing.  After taking into consideration all the relevant testimony and evidence, the hearing officer shall make an administrative decision on whether the taxpayer was erroneously granted a homestead exemption for the taxable year in question.  The taxpayer may appeal the hearing officer's ruling to the circuit court of the county where the property is located as a final administrative decision under the Administrative Review Law.
(f)  A lien against the property imposed under this Section shall be filed with the county recorder of deeds, but may not be filed sooner than 60 days after the notice of intent to record a lien was delivered to the taxpayer if the taxpayer does not request a hearing, or until the conclusion of the hearing and all appeals if the taxpayer does request a hearing.  If a lien is filed pursuant to this Section and the taxpayer received one or 2 erroneous homestead exemptions during any of the 3 collection years immediately prior to the current collection year in which the notice of discovery is served, then the erroneous exemption principal amount, plus 10% interest per annum or portion thereof from the date the erroneous exemption principal amount would have become due if properly included in the tax bill, shall be charged against the property by the chief county assessment officer.  However, if a lien is filed pursuant to this Section and the taxpayer received 3 or more erroneous homestead exemptions during any of the 6 collection years immediately prior to the current collection year in which the notice of discovery is served, the erroneous exemption principal amount, plus a penalty of 50% of the total amount of the erroneous exemption principal amount for that property and 10% interest per annum or portion thereof from the date the erroneous exemption principal amount would have become due if properly included in the tax bill, shall be charged against the property by the chief county assessment officer. If a lien is filed pursuant to this Section, the taxpayer shall not be liable for interest that accrues between the date the notice of discovery is served and the date the lien is filed. Before recording the lien with the county recorder of deeds, the chief county assessment officer shall adjust the amount of the lien to add administrative costs, including but not limited to the applicable recording fee, to the total lien amount.
(g)  If a person received  an erroneous homestead exemption under Section 15-170 and: (1) the person was the spouse, child, grandchild, brother, sister, niece, or nephew of the previous taxpayer; and (2) the person received the property by bequest or inheritance; then the person is not liable for the penalties imposed under this Section for any year or years during which the chief county assessment officer did not require an annual application for the exemption or, in a county with 3,000,000 or more inhabitants, an application for renewal of a multi-year exemption pursuant to subsection (i) of Section 15-170, as the case may be.  However, that person is responsible for any interest owed under subsection (f).
(h)  If the erroneous homestead exemption was granted as a result of a clerical error or omission on the part of the chief county assessment officer, and if the taxpayer has paid the tax bills as received for the year in which the error occurred, then the interest and penalties authorized by this Section with respect to that homestead exemption shall not be chargeable to the taxpayer.  However, nothing in this Section shall prevent the collection of the erroneous exemption principal amount due and owing.
(i)  A lien under this Section is not valid as to (1)  any bona fide purchaser for value  without notice of the erroneous homestead exemption whose rights in and to the underlying parcel arose after the erroneous homestead exemption was granted but before the filing of the notice of lien; or (2) any mortgagee, judgment creditor, or other lienor whose rights in and to the underlying parcel arose before the filing of the notice of lien.  A title insurance policy for the property that is issued by a title company licensed to do business in the State showing that the property is free and clear of any liens imposed under this Section shall be prima facie evidence that the taxpayer is without notice of the erroneous homestead exemption.  Nothing in this Section shall be deemed to impair the rights of subsequent creditors and subsequent purchasers under Section 30 of the Conveyances Act.
(j)  When a lien is filed against the property pursuant to this Section, the chief county assessment officer shall mail a copy of the lien to the person to whom the most recent tax bill was mailed and to the owner of record, and the outstanding liability created by such a lien is due and payable within 30 days after the mailing of the lien by the chief county assessment officer.  This liability is deemed delinquent and shall bear interest beginning on the day after the due date at a rate of 1.5% per month or portion thereof. Payment shall be made to the county treasurer.  Upon receipt of the full amount due, as determined by the chief county assessment officer, the county treasurer shall distribute the amount paid as provided in subsection (k). Upon presentment by the taxpayer to the chief county assessment officer of proof of payment of the total liability, the chief county assessment officer shall provide in reasonable form a release of the lien.  The release of the lien provided shall clearly inform the taxpayer that it is the responsibility of the taxpayer to record the lien release form with the county recorder of deeds and to pay any applicable recording fees.
(k)  The county treasurer shall pay collected erroneous exemption principal amounts, pro rata, to the taxing districts, or their legal successors, that levied upon the subject property in the taxable year or years for which the erroneous homestead exemptions were granted, except as set forth in this Section. The county treasurer shall deposit collected penalties and interest into a special fund established by the county treasurer to offset the costs of administration of the provisions of this Section by the chief county assessment officer's office, as appropriated by the county board. If the costs of administration of this Section exceed the amount of interest and penalties collected in the special fund, the chief county assessor shall be reimbursed by each taxing district or their legal successors for those costs. Such costs shall be paid out of the funds collected by the county treasurer on behalf of each taxing district pursuant to this Section.
(l) The chief county assessment officer in a county with 3,000,000 or more inhabitants shall establish an  amnesty period for all taxpayers owing any tax due to an erroneous homestead exemption granted  in a tax year prior to the 2013 tax year. The amnesty period shall begin on the effective date of this amendatory Act of the 98th General Assembly and shall run through December 31, 2013. If, during the amnesty period, the taxpayer pays the entire arrearage of taxes due for tax years prior to 2013, the county clerk shall abate and not seek to collect any interest or penalties that may be applicable and shall not seek civil or criminal prosecution for any taxpayer for tax years prior to 2013. Failure to pay all such taxes due during the amnesty period established under this Section shall invalidate the amnesty period for that taxpayer.
The chief county assessment officer in a county with 3,000,000 or more inhabitants shall (i)  mail notice of the amnesty period with the tax bills for the second installment of taxes for the 2012 assessment year   and (ii) as soon as possible after the effective date of this amendatory Act of the 98th General Assembly, publish notice of the amnesty period in a newspaper of general circulation in the county. Notices shall include information on the amnesty period, its purpose, and the method by which to make payment.
Taxpayers who are a party to any criminal investigation or to any civil or criminal litigation that is pending in any circuit court or appellate court, or in the Supreme Court of this State, for nonpayment, delinquency, or fraud in relation to any property tax imposed by any taxing district located in the State on the effective date of this amendatory Act of the 98th General Assembly may not take advantage of the amnesty period.
A taxpayer who has claimed 3 or more homestead exemptions in error shall not be eligible for the amnesty period established under this subsection.
(m) Notwithstanding any other provision of law, for taxable years 2019 through 2023, in counties with 3,000,000 or more inhabitants, the chief county assessment officer shall, if he or she learns that a taxpayer who has been granted a senior citizens homestead exemption has died during the period to which the exemption applies, send a notice to the address on record for the owner of record of the property notifying the owner that the exemption will be terminated unless, within 90 days after the notice is sent, the chief county assessment officer is provided with a basis to continue the exemption. The notice shall be sent by first-class mail, in an envelope that bears on its front, in boldface red lettering that is at least one inch in size, the words "Notice of Exemption Termination"; however, if the taxpayer elects to receive the notice by email and provides an email address, then the notice shall be sent by email.

Sec. 10-5. Solar energy systems; definitions. It is the policy of this
State that the use of solar energy systems should be encouraged because they
conserve nonrenewable resources, reduce pollution and promote the health and
well-being of the people of this State, and should be valued in relation to
these benefits.
(a) "Solar energy" means radiant energy received from
the sun at wave lengths suitable for heat transfer, photosynthetic use,
or photovoltaic use.
(b) "Solar collector" means
(1) An assembly, structure, or design, including     passive elements, used for gathering, concentrating, or absorbing direct and indirect solar energy, specially designed for holding a substantial amount of useful thermal energy and to transfer that energy to a gas, solid, or liquid or to use that energy directly; or
(2) A mechanism that absorbs solar energy and     converts it into electricity; or
(3) A mechanism or process used for gathering solar     energy through wind or thermal gradients; or
(4) A component used to transfer thermal energy to a     gas, solid, or liquid, or to convert it into electricity.
(c) "Solar storage mechanism" means equipment or elements (such as
piping and transfer mechanisms, containers, heat exchangers, or controls
thereof, and gases, solids, liquids, or combinations thereof) that are
utilized for storing solar energy, gathered by a solar collector, for
subsequent use.
(d) "Solar energy system" means
(1)(A) A complete assembly, structure, or design of     solar collector, or a solar storage mechanism, which uses solar energy for generating electricity that is primarily consumed on the property on which the solar energy system resides, or for heating or cooling gases, solids, liquids, or other materials for the primary benefit of the property on which the solar energy system resides;
(B) The design, materials, or elements of a system     and its maintenance, operation, and labor components, and the necessary components, if any, of supplemental conventional energy systems designed or constructed to interface with a solar energy system;
(C) Any legal, financial, or institutional orders,     certificates, or mechanisms, including easements, leases, and agreements, required to ensure continued access to solar energy, its source, or its use in a solar energy system, and including monitoring and educational elements of a demonstration project; or
(D)  Photovoltaic electricity generation systems     subject to power purchase agreements or leases for solar energy between a third-party owner, an operator, or both, and an end user of electricity, where such systems are located on the end user of electricity's side of the electric meter and which primarily are used to offset the electricity load of the end user behind whose electric meter the system is connected.  A system primarily is used to offset the electricity load of the end user of electricity if the system is estimated to produce 110% or fewer kilowatt-hours of electricity than consumed by the end user of electricity at such meter in the last 12 full months prior to the system being placed in service.
(2) "Solar energy system" does not include:
(A) Distribution equipment that is equally usable         in a conventional energy system except for those components of the equipment that are necessary for meeting the requirements of efficient solar energy utilization;
(B) Components of a solar energy system that         serve structural, insulating, protective, shading, aesthetic, or other non-solar energy utilization purposes, as defined in the regulations of the Department of Commerce and Economic Opportunity; or
(C) A commercial solar energy system, as defined         by this Code, in counties with fewer than 3,000,000 inhabitants.
(3) The solar energy system shall conform to the     standards for those systems established by regulation of the Department of Commerce and Economic Opportunity.

(35 ILCS 200/10-10)
Sec. 10-10. 
		Valuation of solar energy systems. 
		When a solar energy system
has been installed in improvements on any property, the owner of that property
is entitled to claim, by filing with the chief county assessment officer, an
alternate valuation of those improvements.   When a claim for alternate
valuation is filed, the chief county assessment officer shall ascertain the
value of the improvements as if equipped with a conventional heating or cooling
system and the value of the improvements as equipped with the solar energy
system. So long as the solar energy system is used in total or part as the
means of utilizing solar energy improvements, the alternate valuation computed
as the lesser of the two values ascertained under this paragraph shall be
applied.  When the solar energy system so valued ceases to be used as the means
of heating or cooling those improvements, the owner of that property shall
within 30 days notify the chief county assessment officer in writing
by certified mail.

		Condominiums and cooperatives. 
		In counties with 200,000 or more
inhabitants which classify property, condominiums occupied by the owner as a
residence for a minimum of 6 months during the year and created in accordance
with the provisions of the "Condominium Property Act", as well as land with
improvements owned and operated as a cooperative, shall be assessed on the same
basis of assessment as single family residences in such counties.

(35 ILCS 200/10-20)
Sec. 10-20. 
		Repairs and maintenance of residential property. 
		Maintenance and repairs to residential property owned and used
exclusively for a residential purpose shall not increase the assessed
valuation of the property. For purposes of this Section, work
shall be deemed repair and maintenance when it (1) does not increase the
square footage of improvements and does not materially alter the
existing character and condition of the structure but is limited to work
performed to prolong the life of the existing improvements or to keep the
existing improvements in a well maintained condition; and (2) employs
materials, such as those used for roofing or siding, whose value is not greater
than the replacement value of the materials being replaced.
Maintenance and repairs, as
those terms are used in this Section, to property that enhance the overall
exterior and interior appearance and quality of a residence by restoring
it from a state of disrepair to a standard state of repair do not "materially
alter the
existing character and condition" of the residence.

Sec. 10-25. 
		Model homes, townhomes, and condominium units. 
		If the
construction of a single family dwelling is
completed after December 29, 1986 or the construction of a single family
townhome or condominium unit is completed after the effective date of this
amendatory Act of 1994, and that dwelling, townhome, or condominium unit
is not occupied as a
dwelling but is used as a display or demonstration model home, townhome or
condominium unit for prospective
buyers of the dwelling or of similar homes, townhomes, or condominium units
 to be built on
other property, the
assessed value of the property on which the dwelling, townhome, or
condominium was constructed shall be
the same as the assessed value of the property prior to construction and prior
to any change in the zoning classification of the property prior to
construction of the dwelling, townhome or condominium unit.  The
application of this Section shall not be
affected if the display or demonstration model home, townhome or condominium
unit contains home furnishings,
appliances, offices, and office equipment to further sales activities. This
Section shall not be applicable if the dwelling, townhome, or condominium
unit is occupied as a dwelling or
the property on which the dwelling, townhome, or condominium unit is
situated is sold or leased for use other
than as a display or demonstration model home, townhome, or condominium
unit.  No property shall be eligible
for calculation of its assessed value under this Section for more than a
10-year period. If the dwelling, townhome, or condominium unit becomes
ineligible for the alternate valuation,
the owner shall within 60 days file with the chief county assessment officer a
certificate giving notice of such ineligibility.
For the purposes of this Section, no corporation, individual, sole proprietor
or partnership may have more than a total of 3 model homes, townhomes, or
condominium units at the same time
within a 3 mile radius.  The center point of each
radius shall be the display or demonstration model that has been used as such
for the longest period of time.  The person liable for taxes on property
eligible for assessment as provided in this Section shall file a verified
application with the chief county assessment officer on or before (i)
April 30 of each assessment year for which that assessment is desired in
counties with a population of 3,000,000 or more and (ii) December 31 of
each assessment year for which that assessment is desired in all other
counties. Failure to make a
timely filing in any assessment year constitutes a waiver of the right to
benefit for that assessment year.

		Residential developments
(35 ILCS 200/10-30)
Sec. 10-30. Subdivisions; counties of less than 3,000,000.
(a) In counties with less than 3,000,000 inhabitants, the platting and
subdivision of property into separate lots and the development of the
subdivided property with streets, sidewalks, curbs, gutters, sewer, water and
utility lines shall not increase the assessed valuation of all or any part of
the property, if:
(1) The property is platted and subdivided in     accordance with the Plat Act;
(2) The platting occurs after January 1, 1978;
(3) At the time of platting the property is in excess     of 5 acres; and
(4) At the time of platting the property is vacant or     used as a farm as defined in Section 1-60.
(b) Except as provided in subsection (c) of this Section, the assessed
valuation of property so platted and subdivided shall be determined each year
based on the estimated price the property would bring at a fair voluntary sale
for use by the buyer for the same purposes for which the property was used when
last assessed prior to its platting.
(c) Upon completion of a habitable structure on any lot of subdivided
property, or upon the use of any lot, either alone or in conjunction
with any contiguous property, for any business, commercial or residential
purpose, or upon the initial sale of any platted lot, including a platted
lot which is vacant: (i) the provisions of subsection (b) of this Section
shall no longer apply in determining the assessed valuation of the lot, (ii)
each lot shall be assessed without regard to any provision of this Section, and
(iii) the assessed valuation of the remaining property, when next determined,
shall be reduced proportionately to reflect the exclusion of the property that
no longer qualifies for valuation under this Section. Holding or offering a
platted lot for initial sale shall not constitute a use of the lot for
business, commercial or residential purposes unless a habitable structure is
situated on the lot or unless the lot is otherwise used for a business,
commercial or residential purpose.
(d) This Section applies before the effective date of this amendatory Act of the 96th General Assembly and then applies again beginning January 1, 2012.

Sec. 10-31. Subdivisions; counties of less than 3,000,000.
(a) In counties with less than 3,000,000 inhabitants, the platting and
subdivision of property into separate lots and the development of the
subdivided property with streets, sidewalks, curbs, gutters, sewer, water and
utility lines shall not increase the assessed valuation of all or any part of
the property, if:
(1) The property is platted and subdivided in     accordance with the Plat Act;
(2) The platting occurs after January 1, 1978;
(3) At the time of platting the property is in excess     of 5 acres; and
(4) At the time of platting or replatting the     property is vacant or used as a farm as defined in Section 1-60.
(b) Except as provided in subsection (c) of this Section, the assessed
valuation of property so platted and subdivided shall be determined
based on the assessed value assigned to the property when last assessed prior to its last transfer or conveyance. An initial sale of any platted lot, including a lot that is vacant, or a transfer to a holder of a mortgage, as defined in Section 15-1207 of the Code of Civil Procedure, pursuant to a mortgage foreclosure proceeding or pursuant to a transfer in lieu of foreclosure, does not disqualify that lot from the provisions of this subsection (b).
(c) Upon completion of a habitable structure on any lot of subdivided
property, or upon the use of any lot, either alone or in conjunction
with any contiguous property, for any business, commercial or residential
purpose: (i) the provisions of subsection (b) of this Section
shall no longer apply in determining the assessed valuation of the lot, (ii)
each lot shall be assessed without regard to any provision of this Section, and
(iii) the assessed valuation of the remaining property, when next determined,
shall be reduced proportionately to reflect the exclusion of the property that
no longer qualifies for valuation under this Section. Holding or offering a
platted lot for initial sale shall not constitute a use of the lot for
business, commercial or residential purposes unless a habitable structure is
situated on the lot or unless the lot is otherwise used for a business,
commercial or residential purpose. The replatting of a subdivision or portion of a subdivision does not disqualify the replatted lots from the provisions of subsection (b).
(d) This Section applies on and after the effective date of this amendatory Act of the 96th General Assembly and through December 31, 2011.

Sec. 10-35. Subdivision common areas.
(a) Residential property which is part of a development,
but which is individually owned and ownership of which includes the right,
by easement, covenant, deed or other interest in property, to the use
of any common area for recreational or similar residential purposes shall
be assessed at a value which includes the proportional share of the value
of that common area or areas.
Property is used as a "common area or areas" under this Section if
it is a lot, parcel, or area, the beneficial use and enjoyment of which
is reserved in whole as an appurtenance to the separately owned lots, parcels,
or areas within the planned development.
The common area or areas which are used for recreational or similar
residential purposes and which are assessed to a separate owner and are located
on separately identified parcels, shall be listed for assessment purposes at $1
per year.
(b) In counties with 3,000,000 or more inhabitants, any person desiring to
establish or to reestablish an assessment of $1 for any parcel on the grounds of
common area status under this Section shall submit an application for the
assessment to the assessor.  The application shall be submitted at the time
within which other applications for revisions of assessment may be made under
Section 14-35 by taxpayers in the township where the parcel is located, and
shall be in the form and accompanied by documentation, as the assessor may
require.
(b-5) In counties with fewer than 3,000,000 inhabitants, the chief county assessment officer may require any person desiring to establish or reestablish an assessment of $1 for any parcel on the grounds of common area status under this Section to submit an application for the assessment to the chief county assessment officer.  The application shall be submitted no later than June 30 of the year for which the assessment is sought and shall be in the form and accompanied by documentation that the chief county assessment officer requires.
(c) If a $1 assessment is established pursuant to the application it may be
maintained from year to year so long as the ownership or use of the parcel has
not changed. When any change in ownership, use or other relevant fact occurs it
shall be the duty of the new owner in cases of change in ownership, or of the
current owner in all other cases, to notify the assessor in writing within 30
days of the change.  The notice shall be sent by certified mail, return receipt
requested, and shall include the name and address of the taxpayer, the legal
description of the property, and the permanent index number of the property
where such number exists.  If the failure to give such notification results in
the assessor continuing to assess the property at $1 in subsequent years in
error, the property shall be considered omitted property under Section 9-265.
Nothing in this Section shall be construed to limit the assessor's authority to
annually revise assessments subject to this Section under the procedures of
Section 9-85.
(d) No objection shall be made to the denial of an assessment of $1 under
this Section in any court except under Sections 21-175 and 23-5.  No person may
object to or otherwise challenge the failure of any parcel to receive an
assessment of $1 under this Section in any proceeding in any court unless an
application for the $1 assessment was made under subsections (b) and (b-5) of this
Section.

record or the owner of the beneficial interest of any historic building which
has been
issued a certificate of rehabilitation, to file with the chief county
assessment officer, on or before January 31 of each year, an affidavit stating
whether there has been any change in the ownership or use of such property, the
status of the owner-occupant, or, in the case of a cooperative,
whether there has been a change in the use of the property or a change in the
cooperative form of ownership.  If there has been such a
change, the nature
of this change shall be stated. Failure to file such an affidavit shall, in the
discretion of the chief county assessment officer, constitute cause to revoke
the certificate of rehabilitation. The chief county assessment officer shall
furnish to the owner a form for the affidavit wherein the owner may state
whether there has been any change in the ownership or use of the property or
the status of the owner. If the chief county assessment officer determines that
the historic building is no longer used as an owner-occupied single family
residence or an owner-occupied multi-family residence, or that there has
been a sale or transfer for value of the
historic
building other than to the
first owner-occupant after the issuance of a certificate of rehabilitation,
or that the historic building no longer
meets the definition of a cooperative, he
or she shall revoke the certificate by written notice to the taxpayer of
record, and shall send a copy of that notice to the Department.

valuation provided for in Section 10-90, with the chief county assessment
officer of the county where the land is located, by January 1 of each year for
which that valuation is desired. The application shall be in the form
prescribed by the Department and contain such information as may reasonably be
required to determine whether the applicant meets the requirements of Section
10-90. If the application shows the applicant is entitled to the valuation, the
chief county assessment officer shall approve it; otherwise, he or she shall
reject the application.
When an application has been filed with and approved by the chief county
assessment officer, he or she shall determine the valuation of the land in two
ways as otherwise permitted by law, and as described in Section 10-90, and
shall list those valuations separately. The county clerk, in preparing
assessment books, lists and blanks under Section 9-100, shall include columns

State, and not classified as operating property by any railroad operating in
this State, shall be assessed by the township or other assessor in the county
or township where the structure is located. All provisions relating to the
assessment and taxation of property, shall apply to those bridges. The assessor
shall give in his or her description the quarter section of property, section
of property, township and range in which the bridge is located or terminates in
this State, together with the metes and bounds of the ground occupied by the
bridge and the approaches to it, from the end on the Illinois shore to the
center of the main channel of the stream crossed by the bridge. To obtain the
description, the assessor may employ a competent surveyor, and the expense of
making the survey and description shall be charged as a tax against the
property by the county clerk, on the certificate of the surveyor. One survey of
any bridge and approaches made under this Code, shall be deemed sufficient for
the purpose of subsequent assessment of the bridge or approaches.
In default of the payment of any tax assessed against any bridge company, the
bridge structure and its approaches that are located within this State,
together with the land on which they are located, as described by the assessor,
and the franchise belonging thereto, shall be sold for the tax at the same time
and in the same manner as other property in the county is sold for delinquent
tax. Any county, city, town, school district or other municipal corporation,
interested in the collection of the tax levied upon the bridge, may become the
purchaser at the sale, or at any sale of the property under judgment recovered
upon, or to enforce the collection of the tax; and if the property so sold is
not redeemed, may acquire, hold, sell and dispose of the title.

		Valuation of registered land or land encumbered by
conservation rights; application process.
(a) The person liable for taxes on land eligible for assessment under
Section 10-166 must file a verified application requesting the
registered land or conservation rights valuation with the chief county
assessment officer by January 31 of the first year that the valuation is
desired.  If the application is not filed by January 31, the taxpayer waives
the right to claim that valuation for that year.  The application
shall be in the form prescribed by the Department and shall contain information
as may reasonably be required to determine whether the applicant meets the
requirements of Section 10-166.  If the application shows the applicant is
entitled to the valuation, the chief county assessment officer shall approve
it and maintain that valuation until notified as provided in Section 10-169.
Otherwise, the application shall be rejected. The application shall be
accompanied by the certification provided for in Section 10-167, if required.
(b) When the application has been filed with and approved by the chief
county assessment officer, he or she shall determine the valuation of the land
as otherwise permitted by law and as required under Section 10-166, and shall
keep a record of that valuation.

		Land no longer registered or encumbered by conservation
rights.
(a) In the event the registration agreement or conservation right by which a
portion of land has been valued under Section 10-166 is released or amended and
for purposes of a conservation right has the effect of substantially
diminishing the public benefit, the person liable for taxes on the land shall
notify the chief county assessment officer in writing by certified mail within
30 days after the release or amendment. The person liable for taxes on the land
that is no longer registered or encumbered by the conservation right shall pay
the county collector, by the following September 1, the difference between the
taxes paid in the 10 preceding years or, in the event the reduced valuation has
been in effect for less than 10 preceding years, the difference between the
taxes for the years the reduced valuation has been in effect
as based on a valuation under Section 10-166 and what
the taxes for those years would have been when based on the valuation as
otherwise permitted by this Code, by ordinance adopted under Section 4 of
Article IX of the Illinois Constitution, or both, as the case may be, together
with 10% interest. If the difference is not paid by the following September 1,
the amount of that difference shall be considered as delinquent taxes. In the
event the person liable for taxes on the land fails to notify the chief county
assessment officer in writing by certified mail within 30 days after the
release or amendment of the conservation rights, the property shall be treated
as omitted property under the provisions of this Code.
(b) Subsection (a) shall not apply if:
(1) the registration agreement or conservation right     is released, terminated, or extinguished pursuant to an acquisition by eminent domain of the land registered or encumbered by the conservation right, provided that for purposes of a conservation right the compensation for the conservation right is paid to the grantee of the conservation right; or
(2) the registration agreement or conservation right     is released, terminated, or extinguished in an involuntary judicial proceeding, provided that for purposes of a conservation right all of the proceeds from a sale, exchange, or involuntary conversion of the conservation right are paid to the grantee of the conservation right; or
(3) the conservation right is released, terminated,     or extinguished by the grantee of the conservation right without the consent of the owner of the property encumbered by the conservation right, provided that the owner of the encumbered property subsequently conveys or, in good faith and in cooperation with the Department of Natural Resources, attempts to convey a new conservation right that encumbers the same property and qualifies for valuation under Section 10-166 within 12 months of the release, termination, or extinguishment of the prior conservation right.

(a) This Section establishes an Electric Utility Property Assessment
Task Force to advise the General Assembly with respect to the possible impact
of the Electric Service Customer Choice and Rate Relief Law of 1997 on the
valuation of the real property component of electric generating stations owned
by
electric utilities and, therefore, on the taxing districts in this State in
which electric generating stations are located.
(b) There shall be established and appointed in accordance with this Section
an Electric Utility Property Assessment Task Force.  Such Task Force shall
be chaired by the President of the Taxpayers' Federation of Illinois, who shall
be a non-voting member of the Task Force.  The Task Force shall be composed of
10 voting members, 6 of whom shall be representatives of taxing districts in
which electric generating stations are located and 4 of whom shall be
representatives
of
electric utilities in this State, at least one of
whom shall be from an electric utility serving over 1,000,000 retail customers
in this State and at least one of whom shall be from an electric utility
serving over 500,000 but less than 1,000,000 retail customers in this State.
(c) The voting members of this Task Force shall be appointed
as follows: (i) 3 of the voting members, one of whom shall be
from an electric utility, shall be appointed by
the President of the Senate; (ii)
3 of the voting members, one of whom shall be from an
electric utility, shall be appointed
by the Speaker of the House of Representatives; (iii) 2 of the voting members,
one of whom
shall be from an electric utility, shall be
appointed by the Minority Leader of the Senate; and (iv) 2 of
the voting members, one of whom shall be from an electric utility,
shall be appointed by the Minority Leader of the House of Representatives.
Such appointments shall be made within 30 days after the effective date of this
amendatory Act of 1997.  Members of the Task Force shall receive no
compensation for their services but shall be entitled to reimbursement of
reasonable expenses incurred while performing their duties.
(d) The Task Force shall submit a report to the General Assembly by January
1, 1999 which shall: (i) analyze whether, and to what extent, taxing districts
throughout this State will experience significant sustained erosions of their
property tax bases and property tax revenues as a result of the restructuring
of the electric industry in this State; and (ii) make recommendations for
legislative changes to address any such impacts.
(e) Beginning with the 1997 assessment year through the assessment
year of 1999,
the fair cash value of any electric power generating plant owned as of November
1, 1997, by an electric utility, as that term is defined in Section 16-102 of
the Public Utilities Act, shall be determined using original cost less
depreciation of the electric power generating plant.  When determining
original cost less depreciation, including the original cost less
depreciation of all new construction, the rate or rates of depreciation
applied shall be the same as the rate or rates in effect November
1, 1997, under the Public Utilities Act and the rules and orders of the
Illinois Commerce Commission, irrespective of any change in ownership of the
property occurring after the effective date of the provisions of the Electric
Service Customer Choice and Rate Relief Law of 1997.  Nothing in this
subsection shall be construed to affect the classification of property as real
or personal.  Determinations of original cost less depreciation for purposes of
this subsection shall be made without regard for the use of any accelerated
cost recovery method including accelerated depreciation, accelerated
amortization or other capital recovery methods, or reductions to original cost
of an electric power generating plant made as a result of the provisions of
Senate
Amendment No. 2 to House Bill

(a) This Division may be cited as the Conservation Stewardship Law.
(b) The General Assembly finds that it is in the best interest of this State to maintain, preserve, conserve, and manage unimproved land to assure the protection of these limited and unique environmental resources for the economic and social well-being of the State and its citizens.
The General Assembly further finds that, to maximize voluntary taxpayer participation in conservation programs, conservation should be recognized as a legitimate land use and taxpayers should have a full range of incentive programs from which to choose.
Therefore, the General Assembly declares that it is in the public interest to prevent the forced conversion of unimproved land to more intensive uses as a result of economic pressures caused by the property tax system at values incompatible with their preservation and management as unimproved land, and that a program should be designed to permit the continued availability of this land for these purposes.
The General Assembly further declares that the following provisions are intended to allow for the conservation, management, and assessment of unimproved land generally suitable for the perpetual growth and preservation of such land in this State.

pollution and promoting the use of abundant, high-sulfur, locally available
coal as well as promoting the health and well-being of the people of this
State, and should be valued at 33 1/3% of their fair cash value.

		Definition of low sulfur dioxide emission coal fueled devices. 
		"Low sulfur dioxide emission coal fueled devices" means any device used
or intended for the purpose of burning, combusting or converting locally
available coal in a manner which eliminates or significantly reduces the
need for additional sulfur abatement that would otherwise be required under
State or Federal air emission standards.  The word "device" includes all
machinery, equipment, structures and all related apparatus, including coal
feeding equipment, of a coal gasification facility designed to convert locally
available coal into a low sulfur gaseous fuel and to manage all waste and
by-product streams.

		Method of valuation for low sulfur dioxide emission coal fueled
devices.  To determine 33 1/3% of the fair cash value of any low sulfur dioxide
emission coal fueled device, the Department shall determine the net value which
could be realized by its owner if the device were removed and sold at a fair,
voluntary sale, giving due account to the expense of removal, site restoration,
and transportation.  That net value shall be considered to be 33 1/3% of fair
cash value.

Sec. 11-70. 
		Assessment of railroad companies; definitions. 
		These words and
phrases, for the assessment of the property of railroad companies, and unless
otherwise required by the context shall be defined as follows:
(a) "Railroad company," "railroad," or "company" means any person, company,
corporation or association owning, operating or constructing a railroad, a
suburban or interurban railroad, a switching or terminal railroad, a railroad
station, or a railroad bridge in this State.
(b) "Operating property" means all tracks and right of way, all structures
and improvements on that right of way, all rights and franchises, all rolling
stock and car equipment, and all other property, real or personal, tangible or
intangible connected with or used in the operation of the railroad including
real estate contiguous to railroad right of way or station grounds held for
reasonable expansion or future development.
(c) "Non-operating personalty" means all personal property, tangible and
intangible, held by any railroad company and not included in the definition of
"operating property".
(d) "Non-carrier real estate" means all land, and improvements on that land,
not situated on the right of way of the railroad and not used as operating
property within the meaning of the definition in paragraph (b). Improvements
owned by others and situated on the right of way not used in the operations of
the railroad shall be deemed to be "non-carrier real estate." The Department
shall adopt proper rules and regulations to determine whether any property is
"non-carrier real estate."
(e) "Trackage rights" or "trackage right agreement" means the right by
which one railroad company operates trains in scheduled service over tracks
owned and used by another railroad company and the valuation of trackage rights
shall include the value of all rolling stock, and all tangible or intangible
personal property used or connected therewith.

		Assessment date for railroad companies. 
		The Department shall
assess all property owned or used by railroad companies operating within this
State, as of January first annually, except property found by the Department to
be non-carrier real estate.
The assessment of the property of any railroad company shall be based upon
the value of property defined in Section 11-70, less the percentage of the
total value which consists of operating or non-operating personal property.

(35 ILCS 200/11-80)
Sec. 11-80. 
		Assessment procedure for railroad companies. 
		In assessing
the taxable property of any railroad company, the Department shall first
determine 33 1/3% of the fair cash value of all the property of any railroad
company as a unit, but shall make due allowance for any non-carrier real estate
and all personalty.
The Department shall take into consideration the actual or market value of
the shares of stock outstanding, the actual or market value of all bonds
outstanding and all other indebtedness as is applicable, for operating the
road. In determining the market value of the stock or indebtedness the
Department shall consider quotations for the 5 years preceding the assessment
date; the net earnings of the company during the 5 calendar years preceding the
assessment date; and such other information as the Department may consider as
bearing on the fair cash value of the property.  The valuation by the
Department shall include capital stock and all other property of railroad
companies, except non-carrier real estate.  The above facts shall not be
conclusive upon the Department in determining 33 1/3% of the fair cash value of
the property of a railroad company.
The Department shall determine the equalized assessed value of the taxable
property of every railroad company by applying to its determination of 33 1/3%
of the fair cash value of the property an equalization factor equal to the
statewide average ratio of the equalized assessed value of locally assessed
property to 33 1/3% of the fair cash value of such locally assessed property.
The Department shall assess the value of all operating property acquired by a
railroad company or its wholly-owned subsidiary by trade with a municipality,
which is situated in a state contiguous to Illinois, at no greater value than
the value of the operating property traded to the municipality for the property
 by the railroad company.  The value shall be that value established for the
year immediately preceding the calendar year of the trade.  The assessment
shall not increase, but may decrease, during the 10 years following the
calendar year of the trade.

Sec. 11-80.1. High-speed passenger rail project.  Due to the importance of developing high-speed or faster rail service, the General Assembly finds that it should encourage freight railroad owners to participate in State and federal government programs, including cooperative agreements designed to increase the speed of passenger rail service, that participation in those programs should not result in increased property taxes, and that such an increase in property taxes could negatively impact the participation in those programs.  Therefore, the Department shall take into consideration any potential increase in a property's overall valuation that is directly attributable to the investment, improvement, replacement, or expansion of railroad operating property on or after January 1, 2010, through State or federal government programs, including cooperative agreements, necessary for higher speed passenger rail transportation.  Any such increase in the property's overall valuation that is directly attributable to the investment, improvement, replacement, or expansion of railroad operating property on or after January 1, 2010, through State or federal government programs  necessary for higher speed passenger rail transportation, including cooperative agreements, shall be excluded from the valuation of its real property improvements under Section 11-80.  This Section applies on and after the effective date of this amendatory Act of the 97th General Assembly and through December 31, 2029.

Sec. 11-85. Property schedules. Every railroad company shall, on or before
June 1 of each year, when required, make out and file with the Department a
statement or schedule showing the property held for right of way, whether
owned, leased, or operated under trackage right agreement, and the length of
the first, second, third and other main and all side tracks and turnouts, and
the number of acres of right of way in each county of this State and in each
taxing district of this State, through or into which the road may run. It shall
describe all improvements and stations located on the right of way, giving the
quantity, quality, character and original cost of each. It shall also report
all non-operating personalty owned or controlled by the company on January 1,
giving the quantity, quality, character and location of the same. The report shall also include any potential increase in the property's overall valuation that is directly attributable to the investment, improvement, replacement, or expansion of railroad operating property on or after January 1, 2010, through State or federal governmental programs, including cooperative agreements,  necessary for higher speed passenger rail transportation through December 31, 2029. New companies
shall make the statement on or before the June 1 after the location of their
road.
When the statement has once been made, it is not necessary to report the
description as required above unless directed to do so by the Department, but
the company shall, on or before June 1, annually, report all additions or
changes in its property in this State as have occurred.
The return required by this Section should be made by the using company, but
all property which is operated under one control shall be returned as provided
in this Section.

(i) An enumeration and classification of all rolling     stock and car  equipment owned or leased by the company.  The classification shall show type of equipment and circumstances of ownership and use.  The enumeration shall include rolling stock used over the track of other companies under any trackage right agreement. All other property used in connection with a trackage right agreement shall be listed.
(j) Any other information the Department may require     to determine the fair cash value of the property of any railroad company, or necessary to carry out the provisions of this Code, including information pertaining to any potential increases in the property's overall valuation that is directly attributable to the investment, improvement, replacement, or expansion of railroad operating property on or after January 1, 2010, through State or federal governmental programs, including cooperative agreements, necessary for higher speed passenger rail transportation through December 31, 2029.
Such statements or schedules shall conform to the instructions and forms
prescribed by the Department.
In cases where a railroad company uses property owned by another, the return
shall be made by the using company and all property operated under one control
shall be returned as provided above.

		Every railroad company
subject to assessment in this State shall annually return to the Department a
list of its non-carrier real estate in this State, providing its description,
the current assessed value, and the estimated true value of all non-carrier
real estate both within and outside of this State, and any other information
the Department may require. The Department shall examine the list and make
whatever additions or alterations it may find necessary, and transmit to the
proper assessing officials of each county in which non-carrier real estate is
located, the list described above, together with any other information it
considers pertinent. If additions or alterations to the list are made by the
Department, the revised list shall also be sent to the reporting carrier. The
proper assessing officials of each county shall then assess the non-carrier
real estate in the same manner as similar locally assessed property belonging
to individuals, except that it shall be treated as property belonging to
railroads. If any parcels are not platted, any description is sufficient which
would enable a competent surveyor to locate the property.
Property listed as non-carrier real estate shall also include the property
index number in counties where such a numbering system has been adopted.

this State, the Department shall determine the value of the entire operating
property of the railroad but shall take only that part of the entire value as
is represented by the average percentage of (a) the length of all track
including main, second and additional main track, side track and turnouts
within this State, (b) its gross revenues arising from railroad operations in
this State, (c) the reproduction cost of its operating property within this
State, as determined by the Interstate Commerce Commission of the United
States, or other competent authority, plus additions and betterments, less

superstructures of first, second, third and other main tracks and all side
tracks and turnouts, and the stations and improvements of the railroad company
on the right of way and all other taxable operating property of the railroad
company shall be denominated "railroad track" and shall be so listed and
valued.  "Railroad track" shall be described in the assessment thereof as a
strip of land extending on each side of the track and embracing the same,
together with all the stations and improvements and other taxable operating
property thereon, commencing where the track crosses the boundary line in
entering the taxing district, and extending to where the track crosses the
boundary line leaving the taxing district, or to the point of termination in
the district, as the case may be, containing .... acres, more or less
(inserting name of taxing district, boundary line of same, and number of acres
and length in miles), and when advertised or sold for taxes no other
description is necessary. Where a railroad company has taxable operating
property in taxing districts in which it owns or uses no tracks or trackage
rights, the property shall be described the same as similar property belonging
to individuals.

		Certification of railroad assessments. 
		The equalized assessed
value of the operating property of every railroad company subject to
assessment, when determined as prescribed in Section 11-80, shall be listed and
taxed in the several taxing districts in the proportion that the length of all
the track owned or used in such taxing district bears to the whole length of
all the track owned or used in this state, except the value of all buildings of
an original cost exceeding $1,000, which are considered to have a situs in the
taxing district in which they are located. Where any railroad company operates
in this State, in whole or in part over the tracks of another company, under
any trackage right agreement, the value of the trackage rights, including the
other taxable operating property (except buildings of an original cost
exceeding $1,000) used or connected therewith, shall be taxed in each taxing
district in the proportion that the length of all the track so used under the
agreement, in the taxing district bears to the whole length of all the track so
used in this state. Where a railroad company holds taxable operating property
in a taxing district, and owns or uses no tracks, or trackage rights in that
district, the property shall be taxed in the taxing district.
The Department shall distribute the equalized assessed value of the taxable
property of every railroad company (other than non-carrier real estate), when
determined as prescribed in Section 11-80, to the respective taxing districts
entitled to it and shall certify the same to the county clerks of the
respective counties, who shall extend taxes against those values the same as
against other property in the taxing districts.

proceed to assess the property of the railroad company according to its best
information and judgment at 33 1/3% of its fair cash value, and may add to the
valuation thereof an amount equal to 50% of the valuation.  If good cause is

		Legislative findings. 
		The General Assembly finds that it is
the policy of this State to ensure and encourage the availability of safe
potable water for our cities, villages, towns, and rural residents and that it
has become increasingly difficult and cost prohibitive for smaller cities,
towns, and villages to construct, maintain, or operate, to current standards,
water treatment facilities.  It is the further finding of the General Assembly
that regional treatment facilities capable of supplying several cities,
villages, towns, public water districts, public water commissions, and rural
water companies with treated water offer a viable economic solution to this
concern and it should be the policy of the State to encourage the construction
and operation of regional water treatment facilities capable of providing
treated, potable water to cities, villages, towns, public water districts,
public water commissions, and rural water companies, thereby relieving the
burden on those entities and their citizens from constructing and maintaining
their own individual treatment facilities.

application of an equalization factor and shall set forth the percentage of
increase or decrease represented by the factor. The publication shall be made
on or before December 31 of that year, and shall be printed in some public
newspaper or newspapers published in the county. In every township or
assessment district in which there is published one or more newspapers of

substantially the following form printed in type no smaller than eleven point:
"NOTICE TO TAXPAYERS
Median Level of Assessment--(insert here the median level of assessment
for the assessment district)
Your property is to be assessed at the above listed median level of
assessment for the assessment district.  You may check the accuracy of your
assessment by dividing your assessment by the median level of assessment.  The
resulting value should equal the estimated fair cash value of your property.
If the resulting value is greater than the estimated fair cash value of your
property, you may be over-assessed. If the resulting value is less than the
fair cash value of your property, you may be under-assessed. You may appeal
your assessment to the Board of Review."
The notice published under this Section shall also include the following:
(1) A statement advising the taxpayer that     assessments of property, other than farm land and coal, are required by law to be assessed at 33 1/3% of fair market value.
(2)  The name, address, phone number, office hours,     and, if one exists, the website address of the assessor.
(3) A statement advising the taxpayer of the steps to     follow if the taxpayer believes the full fair market value of the property is incorrect or believes the assessment is not uniform with other comparable properties in the same neighborhood. The statement shall also (i) advise all taxpayers to contact the township assessor's office, in those counties under township organization, first to review the assessment, (ii) advise all taxpayers to file an appeal with the board of review if not satisfied with the assessor review, and (iii) give the phone number to call for a copy of the board of review rules; if the Board of Review maintains a web site, the notice must also include the address of the website where the Board of Review rules can be viewed.
(4) A statement advising the taxpayer that there is a     deadline date for filing an appeal with the board of review and indicating that deadline date (30 days following the scheduled publication date).
(5) A brief explanation of the relationship between     the assessment and the tax bill.
(6) In bold type, a notice of possible eligibility     for the various homestead exemptions as provided in Section 15-165 through Section 15-175 and Section 15-180.
The newspaper shall furnish to the local assessment officers as many
copies of the paper containing the assessment list as they may require.

		Reassessment in disaster areas. 
		In every county which has been
declared a major disaster area by the President of the United States or the
Governor of the State of Illinois, the chief county assessment officer, board
of review or board of appeals shall, upon application by the property owner,
make a reassessment of any taxable property in the county which was
substantially damaged by the disaster. The Department shall advise with the
chief county assessment officers, boards of review or boards of appeals of the
several counties involved in connection with such reassessment.
In the reassessment, the value of the property shall be determined as of the
date of the declaration of the county as a major disaster area. If the value of
any property on that date is, by reason of the disaster, less than the prior
assessment, the assessment for that year shall be arrived at by dividing by 365
the sum of the 2 products obtained (a) by multiplying the prior assessment by
the number of days from January 1 of that year to the date of the declaration
and (b) by multiplying the value of the property as of the date of the
declaration by the number of days from the date of the declaration to December
31 of that year.
If the reassessment and computations occur prior to the adjournment of the
current board of review or board of appeals, the assessment of the property
shall be reduced accordingly. If the board of review or board of appeals has
adjourned at the time of the declaration, the Department shall convene the
board of review or board of appeals to make the reassessment of property
applied for after that adjournment.

		Reassessment order by Department. 
		Whenever it appears to the
Department that the property in any county, or in any assessment district, has
not been assessed in substantial compliance with law, the Department may, in
its discretion, in any year, either before or after the original assessment is
completed by the local assessment officers, order a reassessment by the local
assessing officers for that year of all or any class of the taxable property in
the county or assessment district.  The reassessment shall be substituted for
the original assessment. The order directing a reassessment shall be filed in
the office of the county treasurer of the county in which the reassessment has
been ordered, except in counties having an elective board of review or board of
appeals in which case the order shall be filed with that board.
If any general assessment is not published in any year for which the
assessment was made, or if that publication was not made in time to permit the
examination thereof by the Department in that year, the Department may in any
of the 3 years intervening between the years for which general assessments are
made, order reassessment of the last general assessment of all or any class of
property in the county or assessment district, and the reassessment shall be
substituted for the original general assessment for the intervening year and
thereafter until the next general assessment is made.
No substitute assessment shall invalidate any prior assessment as to taxes
extended thereon.
The Department may order the board of review of any county not having an
elected county assessor and an elective board of review to convene in
extraordinary session for the purpose of further revising, correcting and
equalizing the assessment of property within that county.
When a reassessment has been ordered under this Section, the individual
assessments made under such order shall be reviewed, revised and corrected by
townships or taxing districts by the assessors making the reassessment.
The assessors making the reassessment shall give notice of the order under
which it is made showing the class of property affected by the reassessment,
each township or taxing district to be reviewed, revised and corrected and the
time and place for the revision and correction, by publishing the notice in one
or more newspapers, published and having a general circulation in the county,
at least 5 days before the time set for the revision in each township or taxing
district.

general circulation published in the county in which the reassessment is made,
except that in every township in which there is published one or more
newspapers of general circulation the notice shall be published in one of
those newspapers in each township. The board shall convene at the time and
place fixed in the order, and shall review, correct, return and certify
the reassessment in like manner, and shall have and exercise all the
powers and authority given to boards of review or boards of appeals, and
shall be subject to all the restrictions, duties and penalties of those
boards.  When a reassessment has been ordered, the board, at the time and place
fixed in the notice given as required by this Section, may hear complaints and
review and correct the reassessment by townships or assessment districts, as
the reassessment for such townships or assessment districts is completed and
certified by the chief county assessment officer, without waiting for the
completion of the entire reassessment. Two or more townships or assessment
districts may be notified for a revision and correction at the same time.

Sec. 14-15. Certificate of error; counties of 3,000,000 or more.
(a) In counties with 3,000,000 or more inhabitants, if, after the
assessment is certified pursuant to Section 16-150, but subject to the
limitations of subsection (c) of this Section,
the county assessor discovers an error or mistake in the assessment, the
assessor shall execute a certificate setting forth the nature and cause of the
error.  The certificate when endorsed by the county assessor, or when endorsed
by the county assessor and board of appeals (until the first Monday in December
1998 and the board of review beginning the first Monday in December 1998 and
thereafter) where the certificate is executed for any assessment which was the
subject of a complaint filed in the board of appeals (until the first Monday in
December 1998 and the board of review beginning the first Monday in December
1998 and thereafter) for the tax year for which the certificate is issued,
may, either be certified according
to the procedure authorized by this Section or
be presented and received in evidence in any court of competent
jurisdiction.
Certification is authorized, at the discretion of the county assessor, for:
(1) certificates of error allowing homestead exemptions under Article 15; (2) certificates of error on
residential property
of 6 units or less; (3) certificates of error allowing exemption of the
property pursuant to Section 14-25; and (4) other certificates of error
reducing assessed value by less than $100,000.  Any certificate of error not
certified shall be presented to the court.
The county assessor shall develop reasonable procedures for the filing and
processing of certificates of error.  Prior to the certification or
presentation to the court, the county assessor or his or her designee shall
execute and include in the certificate of error a statement attesting that all
procedural requirements pertaining to the issuance of the certificate of error
have been met and that in fact an error exists.
When so
introduced in evidence such certificate shall become a part of the court
records, and shall not be removed from the files except upon the order of the
court.
Certificates of error that will be presented to the court shall be filed as
an
objection in the application for judgment and order of sale for the year in
relation to which the certificate is made
or as an amendment to the objection
under subsection (b).
Certificates of error that are to be
certified according to the procedure authorized by this Section need not be
presented to the court as an objection or an amendment under subsection
(b). The State's Attorney of the county
in which the property is situated shall mail a copy of any final judgment
entered by the court regarding any certificate of error to the
taxpayer of record for
the year in question.
Any unpaid taxes after the entry of the final judgment by the court or
certification on
certificates issued under this Section may be included in a special tax sale,
provided that an advertisement is published and a notice is mailed to the
person in whose name the taxes were last assessed, in a form and manner
substantially similar to the advertisement and notice required under Sections
21-110 and 21-135.  The advertisement and sale shall be subject to all
provisions of law regulating the annual advertisement and sale of delinquent
property, to the extent that those provisions may be made applicable.
A certificate of error certified under this Section shall be given effect by the county treasurer, who shall mark the tax
books and, upon receipt of one of the following certificates from the county assessor
or the county assessor and the board of
review
where the board of review is
required to endorse the certificate of error,
shall issue refunds to the taxpayer accordingly:
"CERTIFICATION
I, .................., county assessor, hereby certify     that the Certificates of Error set out on the attached list have been duly issued to correct an error or mistake in the assessment."
"CERTIFICATION
I, .................., county assessor, and we,     ........................................................, members of the board of review, hereby certify that the Certificates of Error set out on the attached list have been duly issued to correct an error or mistake in the assessment and that any certificates of error required to be endorsed by the board of review have been so endorsed."
The county treasurer has the power to mark the tax books to reflect
the issuance of certificates of error
certified according to
the procedure authorized in this Section for certificates of error issued under
Section 14-25 or certificates of error
issued to and including 3
years after the date on which the annual judgment and order of sale for that
tax year was first entered.  The county
treasurer has the power to issue refunds to the taxpayer as set forth
above until all refunds authorized by this Section have been completed.
To the extent that the certificate of error obviates the liability for
nonpayment of taxes, certification of a certificate of error according to the
procedure authorized in this Section shall operate to vacate any judgment or
forfeiture as to that year's taxes, and the warrant books and judgment books
shall be marked to reflect that the judgment or forfeiture has been vacated.
(b) Nothing in subsection (a) of this Section shall be construed to
prohibit the execution, endorsement, issuance, and adjudication of a
certificate of error if (i) the annual judgment and order of sale for the tax
year in question is reopened for further proceedings upon consent of the county
collector and county assessor, represented by the State's Attorney, and (ii) a
new final judgment is subsequently entered pursuant to the certificate.  This
subsection (b) shall be construed as declarative of existing law and not as a
new enactment.
(c) No certificate of error, other than a certificate to establish an
exemption under Section 14-25, shall be executed for any tax year more than 3
years after the date on which the annual judgment and order of sale for that
tax year was first entered, except that during calendar years 1999 and 2000 a
certificate of error may
be
executed
for any tax year, provided that the error or mistake in the assessment was
discovered no
more than 3 years after the date on which the annual judgment and order of sale
for that
tax year was first entered.
(d) The time limitation of subsection (c) shall not apply to a certificate
of error correcting an assessment to $1, under Section 10-35, on a parcel that
a subdivision or planned development has acquired by adverse possession, if
during the tax year for which the certificate is executed the subdivision or
planned development used the parcel as common area, as defined in Section
10-35, and if application for the certificate of error is made prior to
December 1, 1997.
(e) The changes made by this amendatory Act of the 91st General
Assembly apply to certificates
of error issued before, on, and after the effective date of this amendatory Act
of the 91st General Assembly.

Sec. 14-20. Certificate of error; counties of less than 3,000,000. In any
county with less than 3,000,000 inhabitants, if, at any time before judgment or
order of sale is entered in any proceeding to collect or to enjoin the
collection of taxes based upon any assessment of any property, the chief county
assessment officer discovers an error or mistake in the assessment (other than
errors of judgment as to the valuation of the property), he or she shall issue
to the person erroneously assessed a certificate setting forth the nature of
the error and the cause or causes of the error.
In any county with less than 3,000,000 inhabitants, if an owner fails to
file
an application for any homestead exemption provided under Article 15 during the previous assessment year and qualifies
for the exemption, the Chief County Assessment Officer pursuant to this
Section,
or the Board of Review pursuant to Section 16-75, shall issue a
certificate of error setting forth the correct taxable valuation of the
property.
The certificate, when properly
endorsed by the majority of the board of review, showing their concurrence, and
not otherwise, may be used in evidence in any court of competent jurisdiction,
and when so introduced in evidence, shall become a part of the court record and
shall not be removed from the files except on an order of the court.

		Certificate of error; tax exempt property. 
		If an exemption is
approved by the Department or by a final court decision in proceedings to
review an exemption decision of the Department under the Administrative Review
Law then a certificate of error shall be issued under Section 14-15 or
14-20
if one of the following is met:
(a) If the property became eligible for the exemption at an
earlier time, a
certificate of error shall be issued
for
the period of eligibility, but in no event, except as otherwise provided in
this subsection (a), for more than the 3 assessment years
immediately preceding the assessment year for which the exemption was
approved. A certificate of error
shall be issued for the period of eligibility, but in no
event for more than the 5 assessment years immediately preceding the assessment
year for which the exemption was approved, if the municipality requests the
certificate of error before January 1, 1995.
(b) If the property is subsequently erroneously assessed as non-exempt,
that
error shall be remedied by the issuance of a certificate of error.
(c) If the owner failed to file an application for exemption, or a
certificate
of status under Section 15-10, for an assessment year following the assessment
year for which the exemption was approved and the property remains eligible for
exemption for the following year.

shall submit the entire return to the chief county assessment officer. However,
only the portions of the return relating to the property for which a
revision or correction is requested shall be a public record. If requested
by the chief county assessment officer, the property owner shall execute a

the return so that the accuracy of the copy submitted to the chief county
assessment officer may be verified.

may not bill, collect, claim a lien for, or sell the arrearages of taxes for
tax
years earlier than the 2 most
recent tax years, including the current tax
year.
If a taxpayer owes arrearages of taxes due to an administrative error, the
county
collector shall send the taxpayer, by certified mail, a notice that
the arrearages of taxes are owed by the taxpayer.  If the notice is mailed to
the
taxpayer on or before October 1 in any year, then (i)  the county collector may send a separate bill for the arrearages of taxes, which may be due no sooner than 30 days after the due date for the next installment of taxes or (ii) the arrearages of taxes may be added to the tax bill for the following year, in which case the taxes are due
in 2 equal installments on June 1 and September 1 in the following year unless
the county has adopted an accelerated method of billing in which case the
arrearages of taxes may be billed separately and shall be due in equal
installments on the dates on which
each installment of taxes is due in the following year.  If
the notice is mailed after
October 1 in any year, then the arrearages of taxes are to be added to the tax
bill for the second year after the notice and are due in 2 equal
installments on June 1 and September 1

second year after the notice unless the county has adopted an accelerated
method of billing in which case the arrearages of taxes may be billed
separately and shall be due in equal
installments on the dates on which each installment of taxes is due in the
second
year after the notice. In no event shall the due dates on the arrearages of taxes be in more than one
tax year.  The arrearages of taxes added to a tax bill under this Section are
to be listed separately on the tax bill.  "Administrative error"
includes but is not limited
to
failure to include
an extension for a taxing district on the tax bill, an error in the
