                              Part I

Item 1.  Business

CSA Income Fund IV Limited Partnership (the "Partnership") was a limited
partnership organized under the provisions of the Massachusetts Uniform
Limited Partnership Act.  The Partnership was composed of CSA Lease Funds,
Inc. (an affiliate of CSA Financial Corp.), the sole General Partner, and
as of December 31, 2002, 2,682 Limited Partners owning 506,776 Units of
Limited Partnership Interest of $100 each. The capital contributions of the
Partners aggregated $50,677,600.  The Partnership was formed on December 21,
1989 and commenced operations on April 18, 1990.

The General Partner of CSA Income Fund IV Limited Partnership completed the
wind-up of the Partnership during 2002, including a final distribution on
December 13, 2002. A Certificate of Cancellation was filed with the
Commonwealth of Massachusetts on January 29, 2003. This Certificate notified
the Commonwealth that CSA Income Fund IV Limited Partnership was dissolved
effective November 30, 2002.

The Partnership was organized to engage in the business of acquiring
income-producing equipment for investment.  The Partnership's principal
objectives were:

1. To acquire and lease equipment, primarily through Operating Leases,
   to generate income during their entire useful life;

2. To provide monthly distributions of cash to the Limited Partners
   from leasing revenues and from the proceeds of sale or other
   disposition of Partnership equipment;

3. To reinvest in additional equipment a portion of lease revenues and
   a substantial portion of Cash From Sales and Refinancing during the
   first years of the Partnership's operations.

The Partnership was formed primarily for investment purposes and not as
a "tax shelter".

The Partnership has no direct employees.  The General Partner has
full and exclusive discretion in management and control of the Partnership.

Selection of the equipment for purchase and lease was based principally on the
General Partner's evaluation of the usefulness of the equipment in commercial
or industrial applications and its estimate of the potential demand for the
equipment at the end of the initial lease term.

The Partnership's equipment may have included:

1. New and reconditioned computer peripheral equipment, computer terminal
   systems and data processing systems manufactured by companies such as
   Compaq Computer Corporation, Dell Computer Corporation, EMC Corporation
   and International Business Machines, Inc. (IBM).

2. New telecommunications and telecomputer equipment consisting
   primarily of private automated branch exchanges (PBX's), advanced
   high-speed digital telephone switching devices, voice/data
   transmission devices and telephone/computer networks as well as
   telephone handsets and facsimile transmission products.
<page>


3. New office equipment consisting primarily of photocopying and
   graphic processing equipment.

4. New highway transportation equipment and new and reconditioned
   transportation equipment consisting primarily of tractors,
   trailers, trucks, intermodal equipment, railroad rolling stock,
   passenger vehicles and corporate or commercial aircraft.

5. Miscellaneous other types of equipment which meets the investment
   objectives of the Partnership.

The equipment leasing industry is highly competitive.  In initiating its
leasing transactions, the Partnership competed with leasing companies,
manufacturers that lease their products directly, equipment brokers, dealers
and financial institutions, including commercial banks and insurance
companies. Many competitors were larger than the Partnership and had access
to more favorable financing.  Competitive factors in the equipment leasing
business primarily involve pricing and other financial arrangements.
Marketing capability is also a factor.

As of December 31, 2002, the Partnership had completed its wind-up and all
of the equipment in the Partnership's portfolio had been sold. The lessees
representing 10% of total revenues during 2002 were as follows:

    America West Airlines, Inc.                       50%
    Citibank, N.A.                                    13%

The Partnership's acquisition and leasing of equipment is described more
fully in Notes 3 and 4 to the Financial Statements included in Item 8.

Item 2.  Properties

The Partnership neither owned nor leased office space or equipment for the
purpose of managing its day-to-day affairs.  The General Partner, CSA Lease
Funds, Inc. ("CLF"), had exclusive control over all aspects of the business
of the Partnership, including provision of any necessary office space. As
such, CLF was compensated through Management fees and reimbursement of
General and Administrative costs related to managing the Partnership's
business. Excluded from the allowable reimbursement to the General Partner,
however, was any of the following:  (1) Expenditures for rent or utilities;
and (2) Certain other administrative items.

Item 3.  Legal Proceedings

The Partnership is not a party to any pending legal proceedings.

Item 4.  Submission of Matters to a Vote of Security Holders

No matters were submitted to a vote of security holders, through the
solicitation of proxies or otherwise, during the fourth quarter of 2002.

Item 7. General Partner's Discussion and Analysis of Financial
        Condition and Results of Operations

Results of Operations
Rental income for the years ended December 31, 2002, 2001 and 2000 was
$1,967,420, $6,501,299, and $9,902,211, respectively. Net income for the
years ended December 31, 2002, 2001 and 2000 was $5,588,214, $578,076, and
$1,048,500, respectively. The decrease in rental income is primarily due to
lease expirations anticipated as the partnership completed the wind-up. Net
income was positively impacted by the sale of two (2) airplane engines from
one of the last major leases remaining in the portfolio that generated a gain
of approximately 3.9 million.  Overall, the sale of equipment during 2002
resulted in a gain of $4,612,626, as compared to a loss of ($347,139) for
year ended 2001, and a gain of $711,614, for the year ended 2000.
Depreciation expense for 2002, 2001 and 2000 was $744,196, $4,975,058, and
$8,056,432,respectively.

Interest income for 2002, 2001 and 2000 was $101,702, $239,047, and $209,433,
respectively. Interest expense was $15,375, $74,425, and $460,138 for the
years ended December 31, 2002, 2001, and 2000, respectively.

Liquidity and Capital Resources

During 2002, the Partnership generated $1,778,505 in cash flow from
Operations, received $2,124,290 in proceeds from short term investments and
$4,996,068 cash flow from the sale of equipment. The Partnership utilized
these funds along with cash on hand to reduce outstanding notes payable by
$316,992 and make cash distributions of $10,580,904 to the Partners.

The General Partner of CSA Income Fund IV Limited Partnership completed the
wind-up of the Partnership during the fourth quarter of 2002. The Partnership
paid a final distribution to the limited Partners of $9.67 per unit on
December 13, 2002.

Including the final distribution, the Partnership has made cash distributions
to the Limited Partners ranging from 102% to 124% of their initial investment,

To the Partners of CSA Income Fund IV Limited Partnership


We have audited the accompanying statements of financial position of CSA

statements are the responsibility of the Partnership's management. Our
responsibility is to express an opinion on these financial statements
based on our audits.

We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the

examining, on a test basis, evidence supporting the amounts and disclosures

principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for our opinion.

As discussed in note 1 of the financial statements, the General Partner
completed the wind up of the Partnership, with a final distribution on

                         CSA INCOME FUND IV LIMITED PARTNERSHIP
                             Notes to Financial Statements
                                 December 31, 2002
(1)  Organization

CSA Income Fund IV Limited Partnership ("the Partnership") was formed under
the Massachusetts Uniform Limited Partnership Act on December 21, 1989 with
an initial investment of $1,000, from its sole General Partner, CSA Lease
Funds, Inc. and the purchase of 10 Limited Partnership Units at $100 each by
an initial Limited Partner.  The Partnership's primary activity was to invest
in equipment to be leased to third parties.  On February 22, 1990, the
Partnership began its offering of Limited Partnership Units.  The Partnership
commenced operations on April 18, 1990. A Certificate of Cancellation was
filed with the Commonwealth of Massachusetts on January 29, 2003. The
Certificate notified the Commonwealth that the CSA Income Fund IV Limited
Partnership was dissolved effective November 30, 2002.

The General Partner of CSA Income Fund IV Limited Partnership completed the
wind-up of the Partnership during the fourth quarter of 2002. The Partnership
paid a final distribution to the Limited Partners of $9.67 per unit on
December 13, 2002.

Distributable cash from operations, sales or refinancing and profits or
losses for federal income tax purposes was allocated 99% to the Limited
Partners and 1% to the General Partner until Payout has occurred, and
thereafter, 85% and 15% respectively. As provided by the Partnership
Agreement, pursuant to Section 8.3 (c), accounting profits from the
sale of equipment as part of the wind-up of the Partnership are allocated
to each partner first in an amount equal to the negative balance in the
Capital Account of each partner.  During the years 2002 and 2001, certain
of these gains were allocated for accounting purposes to the General
Partner to reduce its Capital Account negative balance.

In accordance with the Partnership Agreement, the Partnership was liable to
the General Partner (or its affiliates) for management fees calculated at
5% of gross rental revenues and to certain reimbursable operating expenses
subject to limitations stated in the Partnership Agreement. During 1994, the
Limited Partners approved an Amendment to the Partnership Agreement allowing
for the payment of Management Fees based on gross rental revenues on Sales
Agency leases.

(2)  Significant Accounting Policies

The Partnership records are maintained on the accrual basis of accounting.

The Partnership accounts for equipment leases as operating leases; therefore,
rental income is reported when earned. Equipment purchases are depreciated on
a straight-line basis over the initial term of the lease to estimated
realizable value. On a periodic basis, the Partnership conducted a review of
the residual value of its equipment as compared to the estimated net realizable
values for such equipment upon expiration of the related lease. In connection
with this review , there were no residual value depreciation adjustments in
2002, 2001 or 2000.

Deferred income represented prepaid rentals received for active leases that
were recognized when earned.

No provision for income taxes has been made as the liability for such taxes
is that of the Partners rather than the Partnership. The Partnership's
federal tax return is prepared solely to arrive at the Partners' individual
taxable income or loss as reported on form K-1. Partnership taxable income
in 2002, 2001 and 2000 was $4,917,924, $1,472,230, and $2,102,735,
respectively. The differences between Partnership taxable income and book
income are primarily due to the difference between tax and book depreciation
methods and the related differences in the gain or loss on sales of
equipment.

     CSA INCOME FUND IV LIMITED PARTNERSHIP
                           Notes to Financial Statements

The Partnership considers investments with original maturities of three
months or less to be cash equivalents.

Short-term Investment during 2001 and 2002 represents an interest, as an
interim lender, in an investment secured by an equipment lease obligation
reported at fair and actual value.

The preparation of financial statements in conformity with generally
Accepted accounting principles requires the General Partner to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities as of the
date of the financial statements and the reported amounts of revenue and
expenses during the reporting year.  Actual results could differ from those
estimates.

(3)  Rental Equipment

The Partnership purchased equipment subject to existing leases either
directly from CSA Financial Corp. or the manufacturer.  The purchase price
to the Partnership was equal to the lesser of fair market value or cost as
adjusted, if necessary, for rents received and carrying costs, plus an
acquisition fee of 4% of cost. In accordance with Section 6.4 (b) of the
Partnership Agreement, the total of all acquisition fees paid to the General
Partner shall not exceed 15% of the total Capital Contributions received by
the Partnership. This lifetime acquisition fee limit was met during 1996 and
the General Partner was no longer paid acquisition fees on any new Partnership
equipment acquisitions. Also, in accordance with Sections 8.1 and 8.2 of the
Partnership Agreement, during the year 2000, the Partnership reached it's
expiration period for new equipment acquisitions which led to the announced
wind-up process.

A summary of changes in rental equipment owned and its related accumulated
depreciation is as follows:

(4)  Leases

As of December 31, 2002, there were no remaining leases in the Partnership's
portfolio since all the equipment had been sold as part of the wind-up of
the Partnership. As of December 31, 2001, substantially all of the
Partnership's equipment was leased under 54 separate leases to 35 lessees.
Approximately 11% of the Partnership's equipment portfolio (based on cost)
had been leased outside the United States at that date.  Two leases
represented approximately 63% (50% and 13%, respectively) of the
Partnership's Revenue in 2002 as compared to four lessees representing
approximately 63% (21%, 17%, 14% and 11%, respectively) in 2001 and three
lessees representing 57% (33%, 12% and 12%, respectively) in 2000.

(5) Short Term Investment

During the year ended December 31, 2001, the Partnership purchased an
interest, as an interim lender, in a short-term investment secured by an
equipment lease obligation yielding 7.75% interest.  The Partnership's
portion of the short-term loan participation had been reduced from an
initial investment of $3,800,667 to $2,124,290 as of December 31, 2001, and
was repaid in full during the quarter ended March 31, 2002.

(6)  Notes Payable

Notes payable at December 31, 2001, consisted of three (3) nonrecourse notes
due in monthly installments, with an interest rate of 6.85% per annum.  Such
notes were collateralized by equipment with a cost of $1,299,122 and were
repaid in full during the year ended December 31, 2002. There were no other
notes payable outstanding during 2002.


(7)  Fair Values of Financial Instruments

The following methods and assumptions were used to estimate the fair value
of financial instruments:

Cash, Cash Equivalents and Short-term Investment
The carrying amount of cash, cash equivalents and short-term investment
approximated their fair value due to their short maturity.

Notes Payable
The fair value of the Partnership's notes payable is based on the market price
for the same or similar debt issues or on the current rates offered to the
Partnership for debt with the same remaining maturity. The carrying amount of
notes payable approximated fair value.

are as follows:

In order to complete the Partnership wind-up, an affiliate of the General
Partner, Computer Systems of America, acquired the Partnership's remaining
equipment portfolio having current fair market value of $397,910 for $335,910
in cash and assumed responsibility for payment of remaining Partnership
expenses of $62,000.

During the life of the Partnership, an affiliate of the General Partner, CSA
Financial Corporation ("CSA") had acquired 6,670 units of the Partnership
from Partners who had a need to liquidate their interests. CSA, when
approached, first informed the Limited Partner to consult their Financial
Advisor, since it may be more financially prudent to hold on to the units
until wind-up was completed.  Then, if the Limited Partner still wanted to
sell their units, CSA offered to purchase the units at slightly higher than
other prevailing third party offers.
