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.
-
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.

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.”
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).
-
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.
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.

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.
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.
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.

Note.
This extended period for filing Form 1040X applies only to amounts affected by changes in your foreign tax credit or deduction.
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.

-
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.
Note.
Interest will not be paid on any NOL refund shown on an amended return processed within 45 days of receipt.
-
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.
-
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).
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.

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.

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.
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

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.
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.
