General Instructions
Future Developments

For the latest information about developments related to Form
1040X and its instructions, such as legislation enacted after they
were published, go to www.irs.gov/form1040x.

What's New
Tracking your amended return. Beginning in March 2013,
you can track the status of your amended return using a new
web or toll-free application. Go to IRS.gov and click on “Where's
My Amended Return,” or call 1-866-464-2050. With either
application, you will need to provide the following information:
Your Taxpayer Identification Number (for most taxpayers that
is their social security number),
Your date of birth, and
Your ZIP code.
Form 1040X will be your new tax return, changing your original
return to include new information. The entries you make on Form
1040X under the columns headed Correct amount and Correct
number or amount are the entries you would have made on your
original return had it been done correctly.

TIP

Many find the easiest way to figure the entries for Form
1040X is to first make the changes in the margin of the
return you are amending.

To complete Form 1040X, you will need:
Form 1040X and these separate instructions;
A copy of the return you are amending (for example, 2011
Form 1040), including supporting forms, schedules, and any
worksheets you completed;
Notices from the IRS on any adjustments to that return; and
Instructions for the return you are amending. If you don't have
the instructions, you can order them by calling
1-800-TAX-FORM (1-800-829-3676) or find them online at
www.irs.gov/formspubs. If you are amending a prior year return,
click on “Prior Year Forms and Pubs.”

Purpose of Form

Use Form 1040X to do the following.
Correct Forms 1040, 1040A, 1040EZ, 1040NR, or
1040NR-EZ.
Make certain elections after the prescribed deadline (see
Regulations sections 301.9100-1 through -3 for details).

Cat. No. 11362H

transaction understatements, and fraud. See Pub. 17, Your
Federal Income Tax, for more information.

Change amounts previously adjusted by the IRS. However,
do not include any interest or penalties on Form 1040X; they will
be adjusted accordingly.
Make a claim for a carryback due to a loss or unused credit.
However, you may be able to use Form 1045, Application for
Tentative Refund, instead of Form 1040X. For more information,
see Loss or credit carryback under When To File, later, and the
discussion on carryback claims under Special Situations, later.

When To File

File Form 1040X only after you have filed your original return.
Generally, for a credit or refund, you must file Form 1040X within
3 years (including extensions) after the date you filed your
original return or within 2 years after the date you paid the tax,
whichever is later. If you filed your original return early (for
example, March 1 for a calendar year return), your return is
considered filed on the due date (generally April 15). However, if
you had an extension to file (for example, until October 15) but
you filed earlier and we received it July 1, your return is
considered filed on July 1.

File a separate Form 1040X for each year you are amending.
If you are changing your federal return, you also may need to
change your state return.
Note. Allow 8 to 12 weeks for Form 1040X to be processed.
If you file Form 1040X claiming a refund or credit for
more than the allowable amount, you may be subject to
CAUTION
a penalty of 20% of the disallowed amount. See Penalty
for erroneous refund claim or credit under Interest and Penalties,
later.

Note. The time limit for filing Form 1040X can be suspended for
certain people who are physically or mentally unable to manage
their financial affairs. For details, see Pub. 556, Examination of
Returns, Appeal Rights, and Claims for Refund.

!

Do not file more than one original return for the same
year, even if you have not received your refund or have
CAUTION
not heard from the IRS since you filed. Filing more than
one original return for the same year, or sending in more than
one copy of the same return (unless we ask you to do so), could
delay your refund.

Do not file Form 1040X if you are requesting a refund of
penalties and interest or an addition to tax that you have already
paid. Instead, file Form 843, Claim for Refund and Request for
Abatement.

!

Do not file Form 1040X for an injured spouse claim. Instead,
file Form 8379, Injured Spouse Allocation. But if you are filing
Form 1040X to request an additional refund after filing Form
8379, see Injured spouse claim under Special Situations, later.

Bad debt or worthless security. A Form 1040X based on a
bad debt or worthless security generally must be filed within 7
years after the due date of the return for the tax year in which the
debt or security became worthless. For more details, see section
6511.

Interest and Penalties
Interest. The IRS will charge you interest on taxes not paid by
their due date, even if you had an extension of time to file. The
IRS will also charge you interest on penalties imposed for failure
to file, negligence, fraud, substantial valuation misstatements,
substantial understatements of tax, and reportable transaction
understatements. Interest is charged on the penalty from the due
date of the return (including extensions).

Foreign tax credit or deduction. A Form 1040X to claim or
change a foreign tax credit or deduction for foreign taxes
generally must be filed within 10 years from the due date for
filing the return (without regard to any extension of time to file)
for the year in which the foreign taxes were actually paid or
accrued. For details, see Pub. 514, Foreign Tax Credit for
Individuals.

Penalty for late payment of tax. If you do not pay the
additional tax due on Form 1040X within 21 calendar days from
the date of notice and demand for payment (10 business days
from that date if the amount of tax is $100,000 or more), the
penalty is usually 1 2 of 1% of the unpaid amount for each month
or part of a month the tax is not paid. The penalty can be as
much as 25% of the unpaid amount and applies to any unpaid
tax on the return. This penalty is in addition to interest charges
on late payments. You will not have to pay the penalty if you can
show reasonable cause for not paying your tax on time.

Note. This extended period for filing Form 1040X applies only
to amounts affected by changes in your foreign tax credit or
deduction.
If you are filing Form 1040X to carry back your unused foreign
tax credit, follow the procedures under Loss or credit carryback
next.
Loss or credit carryback. File either Form 1045 or Form
1040X to apply for a refund based on the carryback of a net
operating loss, an unused general business credit, or a net
section 1256 contracts loss; or an overpayment of tax due to a
claim of right adjustment under section 1341(b)(1). If you use
Form 1040X, see the special instructions for carryback claims in
these instructions under Special Situations, later. A Form 1040X
based on a net operating loss or capital loss carryback or a
credit carryback generally must be filed within 3 years (10 years
for carryback of foreign tax credit or deduction) after the due
date of the return (including extensions) for the tax year of the
net operating loss, capital loss, or unused credit. If you use Form
1045, you must file the claim within 1 year after the end of the
year in which the loss, credit, or claim of right adjustment arose.
For more details, see the Instructions for Form 1045.

Penalty for erroneous refund claim or credit. If you file a
claim for refund or credit in excess of the amount allowable, you
may have to pay a penalty equal to 20% of the disallowed
amount, unless you can show a reasonable basis for the way
you treated an item. The penalty will not be figured on any part of
the disallowed amount of the claim that relates to the earned
income credit or on which accuracy-related or fraud penalties
are charged.
Penalty for frivolous return. In addition to any other penalties,
the law imposes a penalty of $5,000 for filing a frivolous return. A
frivolous return is one that does not contain information needed
to figure the correct tax or shows a substantially incorrect tax
because you take a frivolous position or desire to delay or
interfere with the tax laws. This includes altering or striking out
the preprinted language above the space where you sign. For a
list of positions identified as frivolous, see Notice 2010-33,
2010-17 I.R.B. 609, available at www.irs.gov/irb/2010-17_IRB/
ar13.html.

Reducing a casualty loss deduction after receiving hurri­
cane­related grant. You must file Form 1040X by the due date
(as extended) for filing your tax return for the tax year in which
you received the grant. For more information, see
Reimbursement received for hurricane-related casualty loss
under Special Situations, later.

Other penalties. Other penalties can be imposed for
negligence, substantial understatement of tax, reportable
­2­

Form 1040X (Rev. December 2012)

Any Schedules K-1 you received from any partnership, S
corporation, estate, or trust for the year of the loss or credit that
contributed to the loss or credit carryback.
Any form or schedule from which the carryback results, such
as Form 3800; Form 1116, Foreign Tax Credit; Form 6781,
Gains and Losses From Section 1256 Contracts and Straddles;
Form 4684, Casualties and Thefts; or Schedule C or F
(Form 1040).
Forms or schedules for items refigured in the carryback year,
such as Form 6251, Alternative Minimum Tax—Individuals;
Form 3800; or Schedule A (Form 1040).

Retroactive determination of nontaxable disability pay.
Retired members of the uniformed services whose retirement
pay, in whole or in part, is retroactively determined by the
Department of Veterans Affairs (VA) to be nontaxable disability
pay can file claims for credits or refunds using Form 1040X. You
have until the later of (a) 1 year after the determination date, or
(b) the normal deadline for filing a claim for refund or credit. The
normal deadline is the later of 3 years after filing the original
return or 2 years after paying the tax. Attach a copy of an official
letter from the VA granting the retroactive determination of
nontaxable disability pay.

Special Situations

Note. If you were married and you did not have the same filing
status (married filing jointly or married filing separately) for all of
the years involved in figuring the loss or credit carryback, you
may have to allocate income, deductions, and credits. For
details, see the publication for the type of carryback you are
claiming. For example, for NOL carrybacks, see Pub. 536.

Many amended returns deal with situations that have special
qualifications or special rules that must be followed. The items
that follow give you this specialized information so your
amended return can be filed and processed correctly.
Only the special procedures are given here. Unless
otherwise stated, you still must complete all appropriate
CAUTION
lines on Form 1040X, as discussed under Line
Instructions, later.

!

!

CAUTION

Deceased taxpayer. If filing Form 1040X for a deceased
taxpayer, enter “Deceased,” the deceased taxpayer's name, and
the date of death across the top of Form 1040X, page 1.
If you are filing a joint return as a surviving spouse, enter
“Filing as surviving spouse” in the area where you sign the
return. If someone else is the personal representative, he or she
must also sign.
Claiming a refund for a deceased taxpayer. If you are
filing a joint return as a surviving spouse, you only need to file
Form 1040X to claim the refund. If you are a court-appointed
personal representative or any other person claiming the refund,
file Form 1040X and attach Form 1310, Statement of Person
Claiming Refund Due a Deceased Taxpayer, and any other
information required by its instructions. For more details, see
Pub. 559, Survivors, Executors, and Administrators.

Airline payments. Qualified airline employees (which include
former employees or surviving spouses but not covered
executives) who received an airline payment(s) can exclude
from gross income a portion of any payment(s) received by
rolling over that amount to a traditional IRA. Furthermore, any
airline payment(s) rolled over to a Roth IRA may be transferred
to a traditional IRA along with any allocable income. The
maximum amount that can be rolled over or transferred to a
traditional IRA is 90% of the total airline payment(s) received.
Generally, the rollover or transfer to a traditional IRA must have
been done before August 14, 2012, in order to exclude from
gross income any portion of an airline payment(s) received.
To exclude this payment(s) from gross income, you must file
a Form 1040X for the tax year(s) in which the airline payment(s)
was received and included in your gross income. Generally, this
amended return must be filed:
Within 3 years after the date you filed your original return or
within 2 years after the date you paid the tax, whichever is later,
or
by April 15, 2013.
For more information on airline payments, definitions, and
examples, see Rollover of airline payments to traditional IRAs at
www.irs.gov/pub590 or www.irs.gov/form8935.
Be sure to include this reason for filing a Form 1040X with
your explanation in Part III, especially if you are amending a
return from before 2009.

First­time homebuyer credit. If you meet the requirements for
the first-time homebuyer credit, you can amend your return to
take the credit in the prior year.
Homes purchased in 2009. You can no longer claim the
credit on a 2008 return. Use the December 2009 revision of
Form 5405 to claim the credit on your 2009 amended return. Do
not check line F in Part I.
Homes purchased in 2010. You can choose to claim the
credit on your 2009 return for a home you purchased:
After December 31, 2009, and before May 1, 2010, or
After April 30, 2010, and before October 1, 2010, and you
entered into a binding contract before May 1, 2010, to purchase
the property before July 1, 2010.
Homes purchased in 2011. This only applies to members of
the uniformed services or Foreign Service or employees of the
intelligence community who meet the following conditions.
1. You (or your spouse if married) were a member of the
uniformed services or Foreign Service or an employee of the
intelligence community, and
2. You were on qualified official extended duty outside the
United States for at least 90 days during the period beginning
after December 31, 2008, and ending before May 1, 2010.

Carryback claim—net operating loss (NOL). Enter
“Carryback Claim” at the top of page 1 of Form 1040X. Attach a
computation of your NOL using Schedule A (Form 1045) and a
computation of any NOL carryover using Schedule B (Form
1045). A refund based on an NOL does not include a refund of
self-employment tax reported on Form 1040X, line 9. For details,
see Pub. 536, Net Operating Losses (NOLs) for Individuals,
Estates, and Trusts.
Note. Interest will not be paid on any NOL refund shown on an
amended return processed within 45 days of receipt.
Carryback claim—credits and other losses. Enter
“Carryback Claim” at the top of page 1 of Form 1040X. Attach
copies of the following.
Both pages of Form 1040 and Schedules A and D, if
applicable, for the year in which the loss or credit originated.
Enter “Attachment to Form 1040X—Copy Only—Do Not
Process” at the top of these forms.

Form 1040X (Rev. December 2012)

You must attach all appropriate forms and schedules to
Form 1040X or it will be returned.

If you meet these conditions, you can choose to claim the credit
on your 2010 return for a home you purchased:
After December 31, 2010, and before May 1, 2011, or
After April 30, 2011, and before July 1, 2011, and you entered
into a binding contract before May 1, 2011, to purchase the
property before July 1, 2011.
For the definitions of a member of the uniformed services or
Foreign Service, or an employee of the intelligence community,
­3­

Waiver of penalties and interest. If you pay the entire
balance due on your amended return within 1 year of timely filing
your amended return, no interest or penalties will be charged on
the balance due. Payments made after you file Form 1040X
should clearly designate that the payment is to be applied to
reduce the balance due shown on the Form 1040X per IRS
Notice 2008-95.
Special rule for previously filed amended returns. In
order to receive the benefits discussed in this section, you must
notify the IRS if you previously filed an amended return based on
receiving one of the grants mentioned earlier. For instructions on
how to notify the IRS, see Notice 2008-95, 2008-44 I.R.B. 1076,
available at www.irs.gov/irb/2008-44_IRB/ar09.html.

and qualified official extended duty, see the December 2011
revision of the Instructions for Form 5405.
Household employment taxes. If you are correcting the
amount of employment taxes you paid to household employees,
attach Schedule H (Form 1040) and include in Part III of Form
1040X the date the error was discovered. If you owe tax, pay in
full with this return. If you are changing the wages paid to an
employee for whom you filed Form W-2, you must also file Form
W-2c, Corrected Wage and Tax Statement, and Form W-3c,
Transmittal of Corrected Wage and Tax Statements, with the
Social Security Administration. For more information, see Pub.
926, Household Employer's Tax Guide, for the appropriate year.
Injured spouse claim. If you file Form 1040X to request an
additional refund and you do not want your portion of the
overpayment to be applied (offset) against your spouse's
past-due obligation(s), complete and attach another Form 8379
to allocate the additional refund.

Relief for homeowners with corrosive drywall. If you
suffered property losses due to the effects of certain imported
drywall installed in homes between 2001 and 2009, you may be
able to file an amended return to claim a casualty loss for repairs
made to your personal residence or household appliances. For
further information on claiming this loss, see Rev. Proc. 2010-36,
2010-42 I.R.B. 439, available at www.irs.gov/irb/2010-42_IRB/
ar11.html.

Qualified reservist distributions. Reservists called to active
duty after September 11, 2001, can claim a refund of any 10%
additional tax paid on an early distribution from a qualified
retirement plan.
To make this claim:
You must have been ordered or called to active duty after
September 11, 2001, for more than 179 days or for an indefinite
period,
The distribution from a qualified retirement plan must have
been made on or after the date you were ordered or called to
active duty and before the close of your active duty period, and
The distribution must have been from an IRA, or from amounts
attributable to elective deferrals under a section 401(k) or 403(b)
plan or a similar arrangement.
Eligible reservists should enter “Active Duty Reservist” at the
top of page 1 of Form 1040X. In Part III, include the date called
to active duty, the amount of the retirement distribution, and the
amount of the early distribution tax paid. For more information,
see Pub. 590, Individual Retirement Arrangements (IRAs), for
distributions from IRAs; and Pub. 575, Pension and Annuity
Income, for distributions from elective deferral plans.

Resident and nonresident aliens. Use Form 1040X to amend
Form 1040NR or Form 1040NR-EZ. Also, use Form 1040X if you
should have filed Form 1040, 1040A, or 1040EZ instead of Form
1040NR or 1040NR-EZ, or vice versa.
To amend Form 1040NR or 1040NR-EZ, or to file the correct
return, do the following:
Enter your name, address, and social security number (SSN)
or IRS individual taxpayer identification number (ITIN) on the
front of Form 1040X.
Do not enter any other information on page 1. Also, do not
complete Parts I or II on page 2 of Form 1040X.
Enter in Part III the reason why you are filing Form 1040X.
Complete a new or corrected return (Form 1040, Form
1040NR, etc.).
Across the top of the new or corrected return, write
“Amended.”
Attach the new or corrected return to the back of Form 1040X.
For more information, see Pub. 519, U.S. Tax Guide for
Aliens.

Reimbursement received for hurricane­related casualty
loss. If you claimed a casualty loss on your main home resulting
from Hurricanes Katrina, Rita, or Wilma, and later received a
qualified grant as reimbursement for that loss, you can file an
amended return for the year the casualty loss deduction was
claimed (and for any tax year to which the deduction was
carried) to reduce the casualty loss deduction (but not below
zero) by the amount of the reimbursement. To qualify, your grant
must have been issued under Public Law 109-148, 109-234, or
110-116. Examples of qualified grants are the Louisiana Road
Home Grants and the Mississippi Development Authority
Hurricane Katrina Homeowner Grants.
At the top of page 1 of Form 1040X, enter “Hurricane Grant
Relief” in dark, bold letters. Include the following materials with
your amended return.
1. Proof of the amount of any hurricane relief grant received.
2. A completed Form 2848, Power of Attorney and
Declaration of Representative, if you wish to have your
designated representative speak with us. (Do not include this if a
valid Form 2848 is already on file with the IRS that covers the
same tax year and tax matters.)

Signing your child's return. If your child cannot sign the
return, either parent can sign the child's name in the space
provided. Then, enter “By (your signature), parent for minor
child.”
Student loan forgiveness for health care professionals
working in underserved areas. Under the Affordable Care Act
of 2010, health care professionals who received student loan
relief under state programs that encourage individuals to work in
underserved areas may qualify for refunds on their 2009 federal
income tax returns.
Before the enactment of the new law, only amounts received
under the National Health Service Corps Loan Repayment
Program or certain state loan repayment programs eligible for
funding under the Public Health Service Act qualified for the tax
exclusion. The Affordable Care Act expanded the tax exclusion
to include any state loan repayment or loan forgiveness program
intended to increase the availability of health care services in
underserved areas or health professional shortage areas. The
exclusion is retroactive to the 2009 tax year.
To claim this refund, you must file an amended return for
2009. Enter “Excluded student loan amount under 2010
Affordable Care Act” in Part III.

Do not include on Form 1040X any adjustments other
than the reduction of the casualty loss deduction if the

period of limitations on assessment is closed for the tax
year in which you claimed the casualty loss deduction.
Generally, this period is closed if it is more than 3 years after the
return was filed and more than 2 years after the tax was paid.

due later. If one spouse does not pay the tax due, the other may
have to. However, you may qualify for innocent spouse relief.

4, later, for the amount to enter. Remember that the standard
deduction for all years can be increased for the age and/or
blindness of the taxpayer(s). Also, for 2009 and 2010, the
standard deduction can be increased by certain other amounts.
See the form instructions for the year you are amending. None of
these additions to the standard deduction appear on Form
1040EZ, so for more information see the instructions for Form
1040 or 1040A.

You are eliminating a personal exemption for you or your
spouse that you previously claimed, but were not entitled to
claim.
If any of these situations apply to you, complete Form 1040X,
lines 23 through 31.
Multiply the total number of exemptions claimed by the
amount shown in the table below for the year you are amending.
However, if the amount on line 1 of Form 1040X is more than

Example. The taxable income on your original 2011 Form
1040 was $49,650. You used the Tax Table in the 2011
Instructions for Form 1040 to find the tax, $8,544. You are
amending your 2011 Form 1040 to add $160 of interest income,
which you add in on line 1 of Form 1040X. There are no other
changes. According to the 2011 Form 1040 instructions for
line 44 (Tax), you should use the Tax Table to look up the tax on
your corrected taxable income ($49,810). The revised tax shown
in the Tax Table is $8,581. Below is your completed Form

Example. Margaret showed $0 taxable income on her
original return, even though she actually had a loss of $1,000.
She later discovered she had additional income of $2,000. Her
Form 1040X, line 5, would show ($1,000) in column A, $2,000 in
column B, and $1,000 in column C. If she failed to take into
account the loss she actually had on her original return, she

Line 16—Total Payments
Include in the total on this line any payments shown on Form
8689, Allocation of Individual Income Tax to the U.S. Virgin
Islands, lines 40 and 44. Enter “USVI” and the amount on the
dotted line to the left of line 16.

on paying your taxes electronically, including by credit or debit
card or the EFTPS, go to www.irs.gov/e-pay.

Refund or Amount You Owe

What if you cannot pay. If you cannot pay the full amount
shown on line 19, you can ask to make monthly installment
payments. Generally, you can have up to 72 months to pay.
To ask for an installment agreement, apply online or use
Form 9465, Installment Agreement Request. To apply online, go
to IRS.gov, click on “Tools” and then “Online Payment
Agreement.” If you use Form 9465, see its instructions.

The purpose of this section is to figure the additional tax you owe
or excess amount you have paid (overpayment). All of your
payments (for the tax year you are amending) received up to the
date of this amended return are taken into account, as well as
any overpayment on your original return or after adjustment by
the IRS. It is as if you were using the new information to
complete your original return. If the results show a larger
overpayment than before, the difference between the two
becomes your new overpayment. You can choose to receive the
refund or apply it to your estimated tax for the following year. In
either case, it can be used by the IRS to pay other federal or
state debts that still exist. If the results show that you owe, it is
because you do not have enough additional withholding or
because filing your original return with the information you have
now would have resulted in a smaller overpayment or a balance
due.

Note. If you elected to apply any part of an overpayment on
your original return to your next year's estimated tax, you cannot
reverse that election on your amended return.

Line 21—Overpayment Received as Refund
If the IRS does not use your overpayment to pay past due
federal or state debts, the refund amount on line 21 will be sent
separately from any refund you claimed on your original return
(see the instructions for line 17). We will figure any interest and
include it in your refund.

Line 17—Overpayment
Enter the overpayment from your original return. Use the
following chart to find the corresponding line.

Line 22—Overpayment Applied to Estimated Tax
Enter on line 22 the amount, if any, from line 20 you want applied
to your estimated tax for next year. Also, enter that tax year in
the box indicated. No interest will be paid on this amount.
You will be notified if any of your overpayment was used to
pay past due federal or state debts so that you will know how
much was applied to your estimated tax.

If your original return was changed by the IRS and the result
was an additional overpayment of tax, also include that amount
on line 17. Do not include interest you received on any refund.

!

You cannot change your election to apply part or all of
the overpayment on line 20 to next year's estimated tax.

CAUTION

Any additional refund you are entitled to on Form 1040X will
be sent separately from any refund you have not yet received
from your original return.

Part I—Exemptions

If you are changing the number of exemptions claimed on your
return, complete lines 23 through 30, and line 31, if necessary.
Enter the new exemption amount on line 30 and line 4,
column C.

Line 18—Amount Available To Pay Additional Tax
If line 17 is larger than line 16, line 18 will be negative. You will
owe additional tax. To figure the amount owed, treat the amount
on line 18 as positive and add it to the amount on line 10. Enter
the result on line 19.

Line 28—Exemption Amount
To figure the amount to enter on line 28, you may need to use
the Deduction for Exemptions Worksheet in the Form 1040 or
Form 1040A instructions for the year you are amending. To find
out if you do, see Who must use the Deduction for Exemptions
Worksheet under the instructions for line 4, earlier. If you do not
have to use that worksheet, multiply the applicable dollar amount

Line 19—Amount You Owe
You can pay by check, money order, credit or debit card or the
EFTPS.

You can use Form 1040X to have $3 go to the Presidential
Election Campaign Fund if you (or your spouse on a joint return)
did not do so on your original return. This must be done within
201 2 months after the original due date for filing the return. For
calendar year 2012, this period ends on January 2, 2015. A
previous designation of $3 to the fund cannot be changed.

Line 29—Additional Exemption Amount for
Housing Midwestern Displaced Individuals

Part III—Explanation of Changes

If you are claiming or changing a 2009 exemption amount for
housing Midwestern displaced individuals, complete lines 1
through 6 of the 2009 Form 8914, Exemption Amount for
Taxpayers Housing Midwestern Displaced Individuals. Enter the
amount from Form 8914, line 6, on Form 1040X, line 29.
Complete line 30. Be sure to attach Form 8914 to Form 1040X.

The IRS needs to know why you are filing Form 1040X. For
example, you:
Received another Form W-2 after you filed your return,
Forgot to claim the child tax credit,
Discovered you could claim a tuition and fees deduction for
2011,
Changed your filing status from qualifying widow(er) to head
of household,
Did not add the sales tax on your new car to your 2009
standard deduction, or
Are carrying an unused NOL or credit to an earlier year.

Line 31—Dependents
List all dependents claimed on this amended return. This
includes:
Dependents claimed on your original return who are still being
claimed on this return, and
Dependents not claimed on your original return who are being
added to this return.

Paid Preparer

Generally, anyone you pay to prepare your return must sign it
and include their Preparer Tax Identification Number (PTIN) in
the space provided. The preparer must give you a copy of the
return for your records. Someone who prepares your return but
does not charge you should not sign.

If you are now claiming more than four dependents, attach a
separate statement with the required information.
Column (b). You must enter each dependent's social security
number (SSN). If your dependent child was born and died in the
tax year you are amending and you do not have an SSN for the
child, enter “Died” in column (b), and attach a copy of the child's
birth certificate, death certificate, or hospital medical records.
The document must show the child was born alive.
Be sure the name and SSN entered agree with the
dependent's social security card. Otherwise, at the time we
process your return, we may disallow the exemption claimed for
the dependent and reduce or disallow any other tax benefits
(such as the child tax credit) based on that dependent.

Assembling Your Return

Assemble any schedules and forms behind Form 1040X in order
of the “Attachment Sequence No.” shown in the upper right
corner of the schedule or form. If you have supporting
statements, arrange them in the same order as the schedules or
forms they support and attach them last. Do not attach
correspondence or other items unless required to do so,
including a copy of your original return.
Attach to the front of Form 1040X:
A copy of any Forms W-2, W-2c (a corrected Form W-2), and
2439 that support changes made on this return;
A copy of any Form W-2G and 1099-R that support changes
made on this return, but only if tax was withheld; and
A copy of any Forms 1042S, SSA-1042S, RRB-1042S, and
8288-A that support changes made on this return.

Note. For details on how to get an SSN or correct a name or
number, see the 2012 Form 1040, 1040A, or 1040EZ
instructions.
Column (d). Check the box in column (d) if your dependent is
also a qualifying child for the child tax credit. See the Form 1040
or 1040A instructions for the year you are amending to find out
who is a qualifying child and if you must complete Part I of
Schedule 8812.

Attach to the back of Form 1040X any Form 8805 that
supports changes made on this return.
If you owe tax, enclose (do not attach) your check or money
order in the envelope with your amended return. See the
instructions for line 19, earlier.

Reported time and cost burden is a national average and
does not necessarily reflect a “typical” case. Most taxpayers
experience lower than average burden, with taxpayer burden
varying considerably by taxpayer type. The estimated average
time burden for all taxpayers filing a Form 1040X is 7 hours, with
an average cost of $90 per return. This average includes all
associated forms and schedules, across all preparation methods
and taxpayer activities. There is significant variation in taxpayer
activity within these estimates.
