Section references are to the Internal
Revenue Code unless otherwise noted.

What’s New
Carryback of eligible small
business credits. Eligible small
business credits determined in your
first tax year beginning in 2010 are
carried back to each of the 5
preceding tax years, beginning with
the earliest year. See Line
1b–Unused General Business Credit
on page 2.

General Instructions
Purpose of Form

Form 1045 is used by an individual,
estate, or trust to apply for a quick tax
refund resulting from:
• The carryback of an NOL,
• The carryback of an unused
general business credit,
• The carryback of a net section
1256 contracts loss, or
• An overpayment of tax due to a
claim of right adjustment under
section 1341(b)(1).
When carrying back an NOL
to an earlier tax year, an
CAUTION alternative minimum tax
(AMT) liability may be created for that
earlier year. This may be true even if
there was no AMT liability when the
tax return for that earlier year was
filed.
Waiving the carryback period. You
can elect to carry an NOL forward
only, instead of first carrying it back.
To make this election for an NOL
incurred in your 2010 tax year, attach
to your 2010 tax return filed on or
before the due date (including
extensions) a statement that you are
electing under section 172(b)(3) to
relinquish the entire carryback period
for any 2010 NOL. If you filed your
return on time without making the
election, you can still make the
election on an amended return filed
within 6 months of the due date of the
return (excluding extensions). Attach
the election to the amended return,
and write “Filed pursuant to section
301.9100-2” on the election
statement. Once made, the election is
irrevocable.

Definitions
Eligible loss. For an individual, an
eligible loss is any loss of property
arising from fire, storm, shipwreck,
other casualty, or theft.
For a small business (as defined in
section 172(b)(1)(F)(iii)) or a farming
business (as defined in section
263A(e)(4)), an eligible loss is any
loss attributable to a federally
declared disaster (as defined in
section 165(h)(3)(C)(i)).
An eligible loss does not include a
farming loss, a qualified disaster loss,
a qualified GO Zone loss, or a
qualified disaster recovery assistance
loss.
Farming loss. A farming loss is the
smaller of:
• The amount that would be the NOL
for the tax year if only income and
deductions attributable to farming
businesses (as defined in section
263A(e)(4)) were taken into account,
or
• The NOL for the tax year.
A farming loss does not include a
qualified disaster loss.
Qualified disaster loss. A qualified
disaster loss is the smaller of:
1. The sum of:
a. Any losses occurring in a
disaster area (as defined in section
165(h)(3)(C)) and attributable to a
federally declared disaster occurring
before January 1, 2010, plus
b. Any qualified disaster expenses
allowable under section 198A (even if
you did not elect to treat such
expenses as qualified disaster
expenses), or
2. The NOL for the tax year.
Excluded losses. A qualified
disaster loss does not include any
losses from property used in
connection with any private or
commercial golf course, country club,
massage parlor, hot tub facility,
suntan facility, or any store for which
the principal business is the sale of
alcoholic beverages for consumption
off premises.
A qualified disaster loss also does
not include any losses from any
gambling or animal racing property.
Gambling or animal racing property is
any equipment, furniture, software, or
other property used directly in
Cat. No. 13666W

connection with gambling, the racing
of animals, or the on-site viewing of
such racing, and the portion of any
real property (determined by square
footage) that is dedicated to
gambling, the racing of animals, or
the on-site viewing of such racing,
unless this portion is less than 100
square feet.
Qualified GO Zone loss. For 2010,
a qualified GO Zone loss is the
smaller of:
1. The excess of the NOL for the
year over the specified liability loss
for the year to which a 10-year
carryback applies, or
2. The total of any special GO
Zone depreciation or amortization
allowable for specified GO Zone
extension property for the tax year
such property is placed in service
(even if you elected not to claim the
special GO Zone depreciation
allowance for such property).
For more information on the special
GO Zone depreciation allowance, and
the definition of specified GO Zone
extension property, see Publication
536, Net Operating Losses (NOLs)
for Individuals, Estates, and Trusts.
Qualified disaster recovery
assistance loss. For the definition
of qualified disaster recovery
assistance loss, see page 5 of Pub.
4492-B, Information for Affected
Taxpayers in the Midwestern Disaster
Areas.
Specified liability loss. Generally,
a specified liability loss is a loss
arising from:
• Product liability, or
• An act (or failure to act) that
occurred at least 3 years before the
beginning of the loss year and
resulted in a liability under a federal
or state law requiring:
1. Reclamation of land,
2. Dismantling of a drilling
platform,
3. Remediation of environmental
contamination, or
4. Payment under any workers
compensation act.
Any loss from a liability arising
from (1) through (4) above can be
taken into account as a specified
liability loss only if you used an
accrual method of accounting
throughout the period in which the act

(or failure to act) occurred. For
details, see section 172(f).

When To File

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.

!

CAUTION

Be sure to file your 2010
income tax return no later
than the date you file Form

1045.
If you carry back any portion of an
NOL or an unused general business
credit to tax years before the 3 years
preceding the 2010 tax year, you may
need to use additional Forms 1045.
Complete lines 1 through 9 and
Schedule A on only one Form 1045.
Use this Form 1045 for the earliest
preceding tax years. You must sign
this Form 1045, but do not need to
sign the other Forms 1045.

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 2010 income tax
return.

!

CAUTION

Do not include Form 1045 in
the same envelope as your
2010 income tax return.

What To Attach

Attach copies of the following, if
applicable, to Form 1045 for the year
of the loss or credit.
• If you are an individual, pages 1
and 2 of your 2010 Form 1040 and
Schedules A, D, and J (Form 1040), if
applicable.
• Any Form 4952, Investment
Interest Expense Deduction, attached
to your 2010 income tax return.
• All Schedules K-1 you received
from partnerships, S corporations,
estates, or trusts that contribute to the
carryback.
• Any application for extension of
time to file your 2010 income tax
return.
• All Forms 8886, Reportable
Transaction Disclosure Statement,
attached to your 2010 income tax
return.
• Forms 8302, Electronic Deposit of
Tax Refund of $1 Million or More.
• All other forms and schedules from
which a carryback results, such as
Schedule C or F (Form 1040); Form
3800, General Business Credit; Form
6478, Alcohol and Cellulosic Biofuel
Fuels Credit (for years before 2008,
Credit for Alcohol Used as Fuel);
Form 6781, Gains and Losses From
Section 1256 Contracts and
Straddles; or Form 6251, Alternative

Minimum Tax–Individuals; and
related alternative tax net operating
loss deduction calculations.
• Any applicable election statement.
Also attach to Form 1045 copies of
all forms or schedules for items
refigured in the carryback years, such
as Form 3800; Form 6251; or Form
6781.
You must attach copies of all
required forms listed above
CAUTION and complete all lines on
Form 1045 that apply to you.
Otherwise, your application may be
disallowed.

!

Processing the
Application

The IRS will process your application
within 90 days from the later of:
• The date you file the complete
application, or
• The last day of the month that
includes the due date (including
extensions) for filing your 2010
income tax return (or, for a claim of
right adjustment, the date of the
overpayment under section
1341(b)(1)).
The processing of Form 1045 and
the payment of the requested refund
does not 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 also will
generate interest compounded daily.
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.

Disallowance of the
Application

Your application is not treated as a
claim for credit or refund. It may be
disallowed if it has material omissions
or math errors that are not corrected
within the 90-day period. If the
application is disallowed in whole or
in part, no suit challenging the
disallowance can be brought in any
court. But you can file a regular claim
for credit or refund before the
limitation period expires, as explained
later under Form 1040X or Other
Amended Return.
-2-

Excessive Allowances

Any amount applied, credited, or
refunded based on this application
that the IRS later determines to be
excessive may be billed as if it were
due to a math or clerical error on the
return.

Form 1040X or Other
Amended Return

Individuals can get a refund by filing
Form 1040X, Amended U.S.
Individual Income Tax Return, instead
of Form 1045. An estate or trust can
file an amended Form 1041, U.S.
Income Tax Return for Estates and
Trusts. In most cases, you must file
an amended return no later than 3
years after the due date of the return
for the applicable tax year.
If you use Form 1040X or other
amended return, follow the
instructions for that return. Attach to
the amended return a copy of
Schedule A of Form 1045 showing
the computation of the NOL and, if
applicable, a copy of Schedule B of
Form 1045 showing the computation
of the NOL carryover. Complete a
separate Form 1040X or other
amended return for each year for
which you request an adjustment.
The procedures for Form 1040X
and Form 1045 are different. The IRS
is not required to process your Form
1040X within 90 days. However, if we
do not process it within 6 months
from the date you file it, you can file
suit in court. If the IRS disallows your
claim on Form 1040X and you
disagree with that determination, you
must file suit no later than 2 years
after the date we disallow it.

536.

Line 1b—Unused
General Business Credit
If you claim a tentative refund based
on the carryback of an unused
general business credit, attach a

Instructions for Form 1045 (2010)

detailed computation showing how
you figured the credit carryback and a
recomputation of the credit after you
apply the carryback. An unused
eligible small business credit (ESBC)
must be carried back 5 years.
Generally, an unused general
business credit that is not an ESBC
must be carried back 1 year.
However, the new hire retention
credit (Form 5884-B) cannot be
carried back before 2010 and the
credit for small employer health
insurance premiums (Form 8941)
cannot be carried back before 2010
unless it is an ESBC.
For an ESBC, make the
recomputation by including the
carryback first in line 9 of the 2005
Form 6478, Credit for Alcohol Used
as a Fuel. Any such credit not used in
2005 must be carried to 2006 (the
next earliest carryback year), and so
on, by including any remaining
unused ESBC on the following forms.
1. 2006 Form 6478, line 10.
2. 2007 Form 6478, line 10.
3. 2008 Form 6478, line 14.
4. 2009 Form 6478, line 13.
For any general business credit other
than an ESBC, make the
recomputation on the 2009 Form
3800.
ESBCs are the total of the general
business credits (other than the new
hire retention credit and the employer
housing credit) determined in 2010
for an eligible small business. An
eligible small business is a
corporation the stock of which is not
publicly traded, a partnership, or a
sole proprietorship, if its average
annual gross receipts for the
3-tax-year period before 2010 is not
more than $50,000,000. For
additional rules and details, see the
Instructions for Form 3800.
Note. If you are carrying back an
ESBC, write “SBJA 2012” at the top
of page 1 of Form 1045 for the
earliest preceding tax year.
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 figuring the carryback.
See the instructions for Form 3800.

Line 1c—Net Section
1256 Contracts Loss

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 is not
eligible to make this election. To
make the election, check box D at the
top of Form 6781. The amount which
can be used in any prior tax year
Instructions for Form 1045 (2010)

cannot exceed the net section 1256
contract gain in that year and cannot
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
and 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 cannot 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 cannot use Form 1045 to carry
the released general business credits
to earlier years. Instead, you must file
Form 1040X or other amended return
to claim refunds for those years. For
details, see Rev. Rul. 82-154, 1982-2
C.B. 394.

Lines 10 Through
27—Computation of
Decrease in Tax

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 that begin on this page 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
2010 calendar year and you are
carrying an NOL back 2 years. You
enter “2nd” and “12/31/08” in the left
column heading in the spaces
provided. The column heading now
reads “2nd preceding tax year ended
12/31/08.”
For each carryback year, enter in
the column labeled “Before
carryback” the amounts for the
carryback year as shown on your
original or amended return. If the
amounts were previously adjusted by
you or the IRS, enter the amounts
after adjustment.
-3-

Line 10—NOL Deduction
After Carryback

Use the following rules to figure the
tax years to which you must carry an
NOL shown on Schedule A, line 25. If
an NOL is not fully absorbed in a year
to which it is carried, complete
Schedule B to figure the amount to
carry to the next carryback year.
Note. You may need to use
additional Forms 1045 to carry back
an NOL. Complete lines 1 through 9
and Schedule A on only one Form
1045. Use this Form 1045 for the
earliest preceding tax years. You
must sign this Form 1045 but do not
need to sign the other Forms 1045.
General rule. You generally must
carry back the entire NOL to the 2nd
tax year before the loss year. Any
loss not used in the 2nd preceding
year is then carried to the 1st
preceding year. Any loss not applied
in the 2 preceding years can be
carried forward up to 20 years. The
2-year carryback period does not
apply to the portion of an NOL
attributable to an eligible loss; a
farming loss; a qualified disaster, GO
Zone, or disaster recovery assistance
loss; or a specified liability loss.
Eligible losses. To the extent the
NOL is an eligible loss (defined on
page 1), it is carried back to the 3rd
tax year before the loss. Any such
loss not used in that year is carried to
the 2nd and then the 1st preceding
year. Any such loss that is not applied
in the 3 preceding years can be
carried forward up to 20 years.
Only the eligible loss portion of the
NOL can be carried back 3 years.
Example. You have a $20,000
NOL of which only $5,000 is an
eligible loss. The $5,000 eligible loss
is carried back 3 years, but the
remaining $15,000 loss is carried
back only 2 years, even if you had
modified taxable income of more than
$5,000 in the 3rd preceding year.
Farming losses. To the extent the
NOL is a farming loss (defined on
page 1), that part of the loss is
carried back to the 5th tax year
before the loss. Any such loss not
used in that year is carried to the 4th
preceding year and then applied
consecutively forward through the 1st
preceding year. Any such loss not
applied in the 5 preceding years can
be carried forward up to 20 years.
Only the farming loss portion of the
NOL can be carried back 5 years.
Example. You operate a farming
business and incur an NOL of
$50,000 for 2010. $25,000 of the
NOL is attributable to income and
deductions of your farming business;

$10,000 is attributable to a fire in your
personal residence (an eligible loss);
and the remaining $15,000 is
attributable to your spouse’s work as
an employee. The $25,000 farming
loss is carried back 5 years; the
$10,000 eligible loss is carried back 3
years; and the remaining $15,000
loss is carried back 2 years. Any
unused portion of this NOL can be
carried forward up to 20 years.
You can make an election to figure
the carryback period for a farming
loss without regard to the special
5-year carryback rule. To make this
election for 2010, attach to your 2010
income tax return filed by the due
date (including extensions) a
statement that you are electing to
treat any 2010 farming losses without
regard to the special 5-year carryback
rule. If you filed your original return on
time, you can make the election on
an amended return filed within 6
months after the due date of the
return (excluding extensions). Attach
the election to the amended return
and write “Filed pursuant to section
301.9100-2” on the election
statement. Once made, the election is
irrevocable.
Qualified disaster, GO Zone, and
disaster recovery assistance
losses. To the extent the NOL is a
qualified disaster, GO Zone, or
disaster recovery assistance loss
(defined on page 1), that part of the
loss is carried back to the 5th tax year
before the loss. Any such loss not
used in that year is carried to the 4th
preceding year and then applied
consecutively forward through the 1st
preceding year. Any such loss not
applied in the 5 preceding years can
be carried forward up to 20 years.
Only the qualified disaster, GO
Zone, or disaster recovery assistance
loss portions of the NOL can be
carried back 5 years.
Example. You have a $40,000
NOL of which $15,000 is a qualified
disaster loss. The $15,000 qualified
disaster loss is carried back 5 years,
but the remaining $25,000 loss is
carried back only 2 years. Any
unused portion of this NOL can be
carried forward up to 20 years.
You can make an election to figure
the carryback period for a qualified
disaster, GO Zone, or disaster
recovery assistance loss without
regard to the special 5-year carryback
rule. To make this election for 2010,
attach to your 2010 income tax return
filed by the due date (including
extensions) a statement that you are
electing to treat any 2010 qualified
disaster, GO Zone, or disaster
recovery assistance losses without
regard to the special 5-year carryback

rule. If you filed your original return on
time, you can make the election on
an amended return filed within 6
months after the due date of the
return (excluding extensions). Attach
the election to the amended return
and write “Filed pursuant to section
301.9100-2” on the election
statement. Once made, the election is
irrevocable.
Specified liability losses. To the
extent an NOL is a specified liability
loss (defined on page 1), that part of
the loss is carried back to the 10th
tax year before the loss. Any such
loss not used in that year is carried to
the 9th preceding year and then
applied consecutively forward through
the 1st preceding year. Any such loss
that is not applied in the 10 preceding
years can be carried forward up to 20
years.
Only the specified liability loss
portion of the NOL can be carried
back 10 years.
You can make an election to figure
the carryback period for a specified
liability loss without regard to the
special 10-year carryback rule. To
make this election for 2010, attach to
your 2010 income tax return filed by
the due date (including extensions) a
statement that you are electing to
treat any 2010 specified liability
losses without regard to the special
10-year carryback rule. If you filed
your original return on time, you can
make the election on an amended
return filed within 6 months after the
due date of the return (excluding
extensions). Attach the election to the
amended return and write “Filed
pursuant to section 301.9100-2” on
the election statement. Once made,
the election is irrevocable.
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.

If you used TeleFile for your
original return and someone else
could claim you as a dependent on
their return, see Form 1040EZ for the
year in question and complete the
worksheet on the back of that form
(for 2009, Worksheet for Line

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 adjusted gross

Line 17—Alternative
Minimum Tax

The carryback of an NOL or net
section 1256 contracts loss may
affect or cause you to owe alternative
minimum tax. Individuals use Form
6251 to figure this tax. Estates and
trusts use Schedule I (Form 1041).
The 90% limit on the alternative
tax net operating loss deduction
(ATNOLD) does not apply to the
portion of an ATNOLD attributable to
qualified disaster losses, qualified GO
Zone losses, or qualified disaster
recovery assistance losses. Instead,
the ATNOLD for the tax year is
limited to the sum of:
1. The smaller of:
a. The sum of the ATNOL
carrybacks and carryforwards to the
tax year attributable to NOLs other
than qualified disaster losses,
qualified GO Zone losses, or qualified
disaster recovery assistance losses,
or
b. 90% of AMTI for the tax year
(figured without regard to the
ATNOLD and any domestic
production activities deduction), plus
2. The smaller of:
a. The sum of the ATNOL
carrybacks to the tax year attributable
to qualified disaster losses, qualified
GO Zone losses, or qualified disaster
recovery assistance losses, or
b. AMTI for the tax year (figured
without regard to the ATNOLD and
any domestic production activities
deduction) reduced by the amount
determined under (1), above.

(Section B), 8844, 8846, or 8884, if
applicable, to recompute the general
business credits for years before
2008).
If an NOL or net section 1256
contracts loss carryback eliminates or
reduces a general business credit in
an earlier year, you may be able to
carry back the released credit 1 year.

Line 17—Section 1202
Exclusion
Enter as a positive number any gain
excluded under section 1202 on the
sale or exchange of qualified small
business stock.

Schedule B—NOL
Carryover

Complete and file this schedule to
determine the NOL deduction for
each carryback year and the amount
to be carried forward, if not fully
absorbed. Make the same entries in
each column heading as on page 1 of
Form 1045 (see the instructions for
Lines 10 Through 27 on page 3).
In most cases, if an NOL is more
than the modified taxable income for
the 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 year. The amount of the
carryback is in most cases the
excess, if any, of the NOL carryback
over the modified taxable income for
that earlier year. Modified taxable
income is the amount figured on line
9 of Schedule B.
If you carry two or more NOLs
to a tax year, figure your
CAUTION modified taxable income by
deducting the NOLs in the order in
which they were incurred. First,
deduct the NOL from the earliest
year, then the NOL from the next
earliest year, etc. After you deduct
each NOL, there will be a new,
smaller, modified taxable income to
compare to any remaining NOL.

!

Line 2
Do not take into account on this line
any NOL carryback from 2010 or
later. However, do take into account
NOLs that occurred in tax years
before 2010 and are otherwise
allowable as carrybacks or
carryforwards.
Note. If your taxable income is
shown as zero on your tax return (or
as previously adjusted) for any
carryback year, refigure it without
Instructions for Form 1045 (2010)

limiting the result to zero, and enter it
on line 2 as a negative number.

Line 3—Net Capital Loss
Deduction
Individuals. Enter as a positive
number the amount, if any, shown (or
as previously adjusted) on Schedule
D (Form 1040), line 21 (line 18 for
2000 – 2003).
Estates and trusts. Enter as a
positive number the amount, if any,
shown (or as previously adjusted) on
Schedule D (Form 1041), line 16 (line
17 for 2000 – 2003).

Line 4—Section 1202
Exclusion
Enter as a positive number any gain
excluded under section 1202 on the
sale or exchange of qualified small
business stock.

Line 5—Domestic
Production Activities
Deduction
Enter as a positive number the
amount of any domestic production
activities deduction claimed on your
return.

Line 6—Adjustments to
Adjusted Gross Income
If you entered an amount on line 3 or
line 4, you must refigure certain
income and deductions based on
adjusted gross income. These
include:
• The special allowance for passive
activity losses from rental real estate
activities,

•
•
•
•

Taxable social security benefits,
IRA deductions,
Excludable savings bond interest,
The exclusion of amounts received
under an employer’s adoption
assistance program,
• The student loan interest
deduction, and
• The tuition and fees deduction.
For purposes of figuring the
adjustment to each of these items,
your adjusted gross income is
increased by the total of the amounts
on line 3 and line 4. Do not take into
account any NOL carryback from
2010 or later.
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 adjusted gross income 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, Individual
Retirement Arrangements (IRAs), to
refigure your taxable social security
benefits and IRA deductions under
the special rule.
Enter on line 6 the total
adjustments made to the listed items.
Attach a computation showing how
you figured the adjustments.

Line 7—Adjustment to
Itemized Deductions
