Form 8960; Form 8962; and Form 8995 and/or Form 8995-A.
Farming business. A farming business includes the trade
or business of farming. This includes a cattle operation, or
the raising or harvesting of trees bearing fruit, nuts, or other
crops, or ornamental trees, such as evergreen trees, if they
are cut within the first 6 years. For more information, see the

When To File
Generally, you must file Form 1045 within 1 year after the end
of the year in which an NOL, unused credit, net section 1256
contracts loss, or claim of right adjustment arose.
Processing the Application
The IRS will process your application within 90 days from the
later of:

Do not file your 2023 Form 1045 before you file your
2023 income tax return.
!
CAUTION
The processing of Form 1045 and the payment of the
requested refund doesn't mean the IRS has accepted your
application as correct. If the IRS later determines that the
claimed deductions or credits are due to an overstatement of
the value of property, negligence, disregard of rules, or
substantial understatement of income tax, you may have to
pay penalties. Any additional tax will also generate interest
compounded daily.
Where To File
File Form 1045 with the Internal Revenue Service Center for
the place where you live as shown in the instructions for your
2023 income tax return.
Don't include Form 1045 in the same envelope as
your 2023 income tax return.

CAUTION
The IRS may need to contact you or your authorized
representative (for example, your accountant or tax return
preparer) for more information so we can process your
application. If you want to designate a representative for us to
contact, attach a copy of your authorization to Form 1045. For
this purpose, you can use Form 2848, Power of Attorney and
Declaration of Representative.

Additional Information
For more details on NOLs, see Pub. 536.
Specific Instructions
For purposes of the tentative carryback adjustment, any
items over which you and the IRS are in disagreement at the
time of the filing of the application shall be taken into account
in figuring the tax previously figured only if, and to the extent
that, they were reported on the return or were reflected,
before the date of filing the application, in any amounts
assessed (or collected without assessment) as deficiencies
or abated, credited, refunded, or otherwise repaid.
Address
P.O. box. Enter your box number only if your post office
doesn't deliver mail to your street address.
Foreign address. If you have a foreign address, enter the
city name on the appropriate line. Don't enter any other
information on that line, but also complete the spaces below
that line. Don't abbreviate the country name. Follow the
country's practice for entering the postal code and the name
of the province, county, or state.
After figuring the tax previously determined, figure the
decrease in tax previously determined caused by the
carryback and any related adjustments on the basis of the
items of tax taken into account in figuring the tax previously
determined. In figuring any decrease caused by the
carryback or any related adjustment, items must be taken
into account only to the extent that they were reported on the
return, or were reflected, before the date of filing the
application for a tentative carryback adjustment, in amounts
assessed (or collected without assessment) as deficiencies
or abated, credited, refunded, or otherwise repaid.
Line 1b—Unused General Business
Credit
If you claim a tentative refund based on the carryback of an
unused general business credit, attach a detailed
computation showing how you figured the credit carryback
and a recomputation of the credit after you apply the
carryback. Generally, an unused general business credit
must be carried back 1 year.
If you and the IRS are in disagreement as to the proper
treatment of any item, it must be assumed, for purposes of
figuring the decrease in the tax previously figured, that you
reported the item correctly unless, and to the extent that, the
disagreement has resulted in the assessment of a deficiency
(or the collection of an amount without an assessment) or the
allowing or making of an abatement, credit, refund, or other
repayment, before the date of filing the application.
If you filed a joint return (or separate return) for some but
not all of the tax years involved in figuring the unused credit
carryback, special rules apply to figure the carryback. See
the Instructions for Form 3800.
Line 1c—Net Section 1256 Contracts
Loss
Use one pair of columns to enter amounts before and after
carryback for each year to which the loss or credit is being
carried. Start with the earliest carryback year. A net section
1256 contracts loss can be carried back 3 years. See the
instructions for line 10, later, to figure the tax years to which
you can carry an NOL. Use the remaining pairs of columns
for each consecutive preceding tax year until the loss is fully
absorbed. Enter the ordinal number of years the loss is being
carried back and the date the carryback year ends in the
spaces provided in the headings above line 10 for each pair
of columns.
Example. Your tax year is the 2023 calendar year and
you are carrying a farming loss back 2 years. You enter “2nd”
and “12/31/2021” in the left column heading in the spaces
provided. The column heading now reads “2nd preceding tax
year ended 12/31/2021.” In the middle pair of columns, you
enter “1st” and “12/31/2022.” The column heading now reads
“1st preceding tax year ended 12/31/2022.”
An individual can elect to carry back a net section 1256
contracts loss to each of the 3 tax years preceding the loss
year. An estate or trust isn’t eligible to make this election. To
make the election, check box D at the top of Form 6781. The
amount that can be used in any prior tax year can’t exceed
the net section 1256 contract gain in that year and can’t
increase or create an NOL for that year. Reflect the carryback
as a reduction to your adjusted gross income in the “After
carryback” column on line 11. Attach to Form 1045 a copy of
Form 6781 and Schedule D (Form 1040) for the year of the
net section 1256 contracts loss, as well as an amended Form
6781 and an amended Schedule D (Form 1040) for each
carryback year. For more details, see section 1212(c).
Line 9
If an NOL or net section 1256 contracts loss carryback
eliminates or reduces a prior year foreign tax credit, you can’t
use Form 1045 to carry the released foreign tax credits to
earlier years. Also, if the released foreign tax credits result in
the release of general business credits, you can’t use Form
For each carryback year, enter in the column labeled
“Before carryback” the amounts for the carryback year as
-3-
Instructions for Form 1045 (2023)
shown on your original or amended return. If the amounts
were previously adjusted by you or the IRS, enter the
amounts after adjustment.
After carryback. If you itemized deductions in the
carryback year, enter in the column labeled “After carryback”
the total of your deductions after refiguring any that are based
on, or limited to a percentage of, your AGI. To refigure your
deductions, use your refigured AGI (Form 1045, line 11, using
the “After carryback” column).
Line 10—NOL Deduction After
Carryback
Don't refigure your charitable contributions
Use the following rules to figure the tax years to which you

deduction.
!
CAUTION
If you have an NOL, see Pub. 536 for more information
and examples.
If you didn't itemize deductions in the carryback year,
enter your standard deduction for that year.
General rule. Generally, only an NOL from some farming
losses and an NOL of some insurance companies can be
carried back 2 years. See section 172 and Publication 536 for
details.
(defined earlier), the carryback period is 2 years. Any such
loss not absorbed in the 2 preceding tax years can be carried
forward to each tax year following the tax year of loss. The
loss deduction entered on line 10 is the amount allowed for
each year.
The portion of any NOL not applied in the 2 preceding tax
years can be carried forward to tax years succeeding the loss
year until it is fully absorbed.
Example. You operate a farming business and incur an
NOL of $50,000 for 2023. $35,000 of the NOL is from income
and deductions of your farming business; $15,000 is from
another business. The $35,000 farming loss is carried back 2
years to 2021; the remainder of the loss (nonfarm loss) isn't
eligible for carryback and must be carried forward.
Line 14—Exemptions
Individuals. For 2018 through 2025, individuals’ personal
exemption amounts are zero.
Estates and trusts. Enter in the columns labeled “Before
carryback” and “After carryback” for each applicable
carryback year the amount shown (or as previously adjusted)
on Form 1041, line 21, for 2020, 2021, and 2022.
Line 16—Income Tax
Use your refigured taxable income (Form 1045, line 15, using
the “After carryback” column) to refigure your tax for each
carryback year. Include any tax from Form 4970, Tax on
Accumulation Distribution of Trusts, and Form 4972, Tax on
Lump-Sum Distributions. Attach any schedule used to figure
your tax or an explanation of the method used to figure the
tax and, if necessary, a detailed computation.
Special rules. Special rules apply if you filed a joint return
(or a separate return) for some but not all of the tax years
involved in figuring an NOL carryback. For details, see Pub.
536. Attach a computation showing how you figured the
carryback.
For example, write “Tax Computation Worksheet—2020” if
this is the method used for that year. You don't need to attach
a detailed computation of the tax in this case.
Line 17—Excess Advance Premium
Tax Credit Repayment/Excess
Line 11—Adjusted Gross Income
Enter in the column labeled “Before carryback” your adjusted
gross income (AGI) for the carryback year as shown on your
original or amended return.

Tax Credit (PTC), for your carryback year(s) to figure/refigure
the amount of your premium tax credit (PTC), advance
payment of the premium tax credit (APTC), and excess
APTC, for the “before carryback” and “after carryback”
columns. Include any excess APTC on line 17 for both the
“before carryback” and “after carryback” columns.
Enter in the column labeled “After carryback” your AGI
refigured after you apply the NOL, or net section 1256
contracts loss carryback, and after you refigure any items of
income, credits, and deductions that are based on, or limited
to, a percentage of your AGI. Amounts to refigure may
include:
For carryback year 2021, include any excess advance
payments of the child tax credit on line 17 for both the “before
carryback” and “after carryback” columns. See the 2021
Instructions for Schedule 8812 (Form 1040) for information
regarding calculating/recalculating the credit, advance

Schedule B—NOL Carryover
Complete and file this schedule to figure the NOL deduction

earliest year to which it is carried, you must file Schedule B to
figure the amount of the NOL to be carried to the next tax

For purposes of figuring the adjustment to each of these
items, your AGI is increased by the total of the amounts on
line 3 and line 4. Don't take into account any NOL carryback
from 2023 or later.
If you carry two or more NOLs to a tax year, figure
your modified taxable income by deducting the NOLs
In most cases, figure the adjustment to each item of
income or deduction in the order listed above and, when
figuring the adjustment to each subsequent item, increase or
decrease AGI by the total adjustments you figured for the
previous items. However, a special rule applies if you
received social security benefits and deducted IRA
contributions. Use the worksheets in Pub. 590-A,
Contributions to Individual Retirement Arrangements (IRAs),
to refigure your taxable social security benefits and IRA
deductions under the special rule.

new, smaller, modified taxable income to compare to any
remaining NOL.
