tax. It applies to taxpayers who have
certain types of income that receive
favorable treatment, or who qualify for
certain deductions, under the tax law.

Good records will help you explain any
item and arrive at the correct AMT.
Keep records that show how you
figured income, deductions, etc., for the
AMT. Also keep records of any items
that you used to figure the AMT that
differ from what you used to figure the
regular tax. For example, you will need
to separately figure and track certain
carrybacks, carryforwards, basis
amounts, depreciation, and loss
General Instructions
Future Developments
For the latest information about
developments related to Form 6251 and
its instructions, such as legislation
enacted after they were published, go to
taxpayers with higher economic
incomes. The AMT sets a limit on the
amount these benefits can be used to
reduce total tax.
Also use Form 6251 to figure your
tentative minimum tax (Form 6251,
line 9). You may need to know that
amount to figure the tax liability limit on
earlier.
limitation amounts that differ between
the AMT and the regular tax.
What's New
Exemption amount. The exemption
amount on Form 6251, line 5, has
increased to $73,600 ($114,600 if
married filing jointly or qualifying
widow(er); $57,300 if married filing
separately).
If you refigure an item for AMT by
completing an AMT version of a form or
worksheet, keep a copy of that AMT
form or worksheet for your records.
Figuring AMT Amounts
For the AMT, certain items of income,
deductions, etc., receive different tax
treatment than for the regular tax.
Partners and Shareholders
Also, the amount used to determine
the phaseout of your exemption has
increased to $523,600 ($1,047,200 if
married filing jointly or qualifying
widow(er)).
AMT tax brackets. For 2021, the 26%
tax rate applies to the first $199,900
($99,950 if married filing separately) of
taxable excess (the amount on line 6).
This change is reflected on lines 7, 18,
and 39.
If you are a partner in a partnership or a
shareholder in an S corporation, see
Schedule K-1 and its instructions to
figure your adjustments or preferences
from the partnership or S corporation to
include on Form 6251.
Therefore, you will need to figure items
for the AMT differently from how you
figured them for the regular tax. These
instructions will help you figure AMT
items by using the amount you figured
for the regular tax and refiguring it for
the AMT. In some cases, it is easiest to
refigure an item for AMT by completing
a tax form or worksheet a second time
using additional AMT instructions.
These instructions refer to such a form
or worksheet as an “AMT” version. If
you do complete an AMT version of a
form or worksheet, don’t attach it to your
tax return unless instructed to do so. For
example, you may have to attach an
AMT Form 1116, Foreign Tax Credit, to

enter “RPI” on the dotted line next to
line 6. Otherwise, don’t change line 6.
2. You claim any general business
credit, and either line 6 (in Part I) of
Form 3800 or line 25 of Form 3800 is
more than zero.
3. You claim the qualified electric
vehicle credit (Form 8834), the personal

refueling property credit (Form 8911), or
the credit for prior year minimum tax
(Form 8801).
4. The total of Form 6251, lines 2c
through 3, is negative and line 7 would
be greater than line 10 if you didn’t take
into account lines 2c through 3.
As you figure some deductions and
credits for the AMT, carrybacks or
carryforwards to other tax years may be
different from what you figured for the
regular tax. Examples are investment
interest expense, a net operating loss, a
capital loss, a passive activity loss, and
the foreign tax credit. Your at-risk limits
and basis amounts may also differ for
the AMT.

AMT for 2021, you may be able to take
a credit on Form 8801 for 2022.
Recordkeeping
You must keep records to support items
reported on Form 6251 in case the IRS
has questions about them. If the IRS
examines your tax return, you may be
asked to explain the items reported.
