General Instructions

(Section references are to the Internal

Revenue code.)

Purpose of Form

Paperwork Reduction Act Notice.

We ask for the information on this form

to carry out the Internal Revenue laws of

the United States. You are required to

give us the information. We need it to

ensure that you are complying with

these laws and to allow us to figure and

collect the right amount of tax. Specific Instructions

Form 8801 is used by individuals, trusts,

and estates to compute the minimum

tax credit, if any, for alternative minimum

tax (AMT) incurred in prior tax years after

1986. The form is also used to figure

any minimum tax credit carryforward

that may be used in future years. The AMT is attributable to two types of

adjustments and tax preference items—

“exclusion items” and “deferral items.”

The minimum tax credit is allowed only

on the AMT attributable to deferral

items.

Who Should File

The time needed to complete and file

this form will vary depending on

individual circumstances. The estimated

average time is:

Deferral items are generally

adjustments and tax preference items

that do not cause a permanent

difference in taxable income over a

number of years. An example is

depreciation. Exclusion items, on the

other hand, cause a permanent

Form 8801 should be completed by

individuals, trusts, and estates that had:

Recordkeeping 1 hr., 33 min.

● An AMT liability in 1990 and

adjustments or tax preference items

(other than exclusion items) in 1990;

Learning about the 

law or the form 1 hr., 3 min.

Preparing the form 1 hr.

● A minimum tax credit carryforward

from 1990 to 1991; or

Copying, assembling, and 

sending the form to the IRS 17 min.

● A 1990 unallowed nonconventional

source fuel credit or unallowed orphan

drug credit (see the instructions for line

20 of this form).

If you have comments concerning the

accuracy of these time estimates or

suggestions for making this form more

simple, we would be happy to hear from

Part II

Part I

New Form 8827, Credit for Prior Year

Minimum Tax—Corporations, is used by

corporations to compute the minimum

tax credit and any minimum tax

carryforward that may be used in future

years.
Line 1—Form 1041 filers.—Skip lines 1

through 3 of Form 8801. Complete Parts

I and II of another 1990 Form 8656,

Alternative Minimum Tax—Fiduciaries.

For Part I of Form 8656, take into

account only exclusion items (the

amounts included on lines 4e and 6d of

Form 8656). On line 9 of Form 8656, use

the minimum tax credit net operating

loss deduction (MTCNOLD). However, do

not limit the MTCNOLD to 90% of the

amount on line 8 of Form 8656 (see the

instructions for line 3 below for how to

compute the MTCNOLD). On Part II of

Form 8656, do not take into account any

basis adjustments arising from deferral

items in completing lines 18 and 19. If

the amount on line 12 of Form 8656 is

zero or less, enter -0- on line 4 of Form

8801. Otherwise, enter the amount from

line 12 of Form 8656 on line 4 of Form

8801.

Form 8801 (1991) Page 2

Step 4. Complete Part IV of Form 1116.

Enter the refigured credit from line 32 of

Form 1116 on line 12 of Form 8801. 

For loss years beginning before 1987,

the amount of MTCNOL that may be

carried forward to tax years beginning

after 1986 is equal to the amount of

regular tax NOL that may be carried

from such loss years to the first tax year

beginning after 1986.

Line 20.—Enter the unused portion of

your 1990 credit for fuel produced from

a nonconventional source that was not

allowed solely because of the limitation

under section 29(b)(5)(B).

To determine the amount of MTCNOL

that may be carried to tax years other

than 1990, apply sections 172(b)(2) and

172(d), with appropriate modifications to

take into account exclusion items.

Also include on this line the unused

part of your 1990 orphan drug credit not

allowed solely because of the limitation

under section 28(d)(2)(B).

Line 4.—If you are married filing a

separate return and line 4 is greater than

$155,000, you must include an

additional amount on line 4. If line 4 is

$235,000 or more, include an additional

$20,000 on line 4. Otherwise, include

25% (.25) of the excess of the amount

on line 4 over $155,000. For example, if

the amount on line 4 is $175,000, enter

$180,000 instead—the additional $5,000

is $20,000 ($175,000 minus $155,000)

times 25% (.25).

Line 21.—If line 21 is zero or less, you

do not have a minimum tax credit or a

minimum tax credit carryforward. Do not

complete the rest of this form.

Line 22.—Follow the instructions below

and refer to your 1991 income tax return

to figure the amount to enter on line 22.

Form 1040.—Subtract from the amount

on line 40 the total of any credit on lines

41 through 44 (not including any credit

for prior year minimum tax) and any

write-in credit on line 45 for the credit for

fuel produced from a nonconventional

source.

Line 9.—If you are completing this form

for a child who was under age 14 on

January 1, 1991, and at least one of the

child’s parents was alive on December

31, 1990, do not follow the instructions

on the form for line 9. If line 8 is equal to

or more than line 5, enter -0-; otherwise,

enter the smaller of: (1) the amount by

which line 5 exceeds line 8, or (2) the

amount entered on line F of the

worksheet for line 13 of the child’s 1990

Form 6251.

Note: If you included any of the

exclusion items on a line other than

those listed above, include that item in

the amount to be entered on line 2. For

example, if depletion was included on

Form 6251 as an adjustment on line 4s

(passive activity loss) instead of on line

5c (depletion), include it as an exclusion

item when figuring the amount for line 2.

Form 1040NR.—Subtract from the

amount on line 38 the total of any

credits on lines 39 through 41 (not

including any credit for prior year

minimum tax) and any write-in credit on

line 42 for the credit for fuel produced

from a nonconventional source.

Line 12—Minimum tax foreign tax

credit.—Refigure your 1990 minimum

tax foreign tax credit using only

exclusion items that were attributable to

sources outside the United States. To do

this, use a 1990 Form 1116, Foreign Tax

Credit, and follow the steps below.

Form 1041.—Subtract the total of any

credits on lines 2a through 2c, Schedule G

from the amount on line 1, Schedule G.

Line 3—Minimum tax credit net

operating loss deduction

(MTCNOLD).—Your MTCNOLD is the

aggregate of the minimum tax credit net

operating loss (MTCNOL) carryovers and

MTCNOL carrybacks to 1990. The

MTCNOLD is not limited to 90% of

alternative minimum taxable income

(AMTI) computed by taking into account

only exclusion items. Your MTCNOL is

figured as follows: Step 1. Use a separate Form 1116 for

each type of income.

Step 2. Fill in Part I of Form 1116 using

that portion of your taxable income and

exclusion items that were attributable to

sources outside the United States.

Line 25.—Enter the minimum tax credit

on the following line of your tax return:

Form 1040, line 44.

Form 1040NR, line 41.

Step 3. Fill in Part III of Form 1116.

However, instead of entering the AMT

foreign tax credit carryforward on line 10

Form 1041, line 2d, Schedule G.

For loss years beginning after 1986,

your MTCNOL is the excess of the

deductions allowed in computing AMTI

(excluding the MTCNOLD), taking into

account only exclusion items, over the

income included in computing AMTI,

taking into account only exclusion items.

This excess is computed with the

modifications contained in section

172(d), taking into account exclusion

All others.—Enter the minimum tax

credit on the line provided on your tax

return.

For example, the limitation of

nonbusiness deductions to the amount

of nonbusiness income must be

separately computed in figuring the

MTCNOL using only nonbusiness

income and nonbusiness deductions

taking into account only exclusion items.

However, ignore the disallowance of the

deduction for personal exemptions

under section 172(d)(3) because it has

already been taken into account in

computing AMTI using only exclusion

items.

Line 26—Carryforward of minimum tax

credit.—Keep a record of this amount

because it can be carried forward and

used in future years.

Line 2.—Enter on this line the

adjustments and tax preference items

treated as exclusions.

Exclusion items are your AMT

adjustments and tax preference items

for: the standard deduction, personal

exemptions, estate or trust exemption,

itemized deductions (including any

investment interest expense reported on

Schedule E), the deduction for charitable

contributions of appreciated property,

certain tax-exempt interest, and

depletion.

Combine lines 4a through 4h and 5a

through 5c of your 1990 Form 6251.

Enter the amount on line 2.

If line 13 of Form 1116 was greater

than line 20 of Form 1116, keep a record

of the difference between those two

lines. This amount is carried forward and

used to compute your foreign tax credit

on exclusion items next year.
