If you discover an error after your return has been mailed, you may need to amend your return. The service center may correct errors in math on a return and may accept returns with certain forms or schedules left out. In these instances, do not amend your return! However, do file an amended return if your filing status, your income, your deductions or credits were incorrect.
Use Form 1040-X, Amended U.S. Individual Income Tax Return, to correct a previously filed Form 1040, Form 1040-A, Form 1040-EZ, Form 1040-NR, or Form 1040-NR-EZ. If you are filing to claim an additional refund, wait until you have received your original refund (you may cash that check). To avoid penalty and interest, if you owe additional tax for a tax year, file Form 1040X and pay the tax by April 15 of the following year. If the due date falls on a Saturday, Sunday, or legal holiday, the due date is delayed until the next business day. The Instructions 1040-X list the addresses for the service centers.
File a separate Form 1040X for each year you are amending. Mail each form in a separate envelope. Be sure to indicate the year of the return you are amending on the front of Form 1040X.
The Form 1040X has been redesigned for tax year 2009. Previously the form consisted of three columns; Column A-Original amount, Column B-Net change, and Column C-Correct amount. The redesigned form now has just one column where the Correct Amount is the only figure entered, making it easier to make changes to previously filed returns. There is an area on the front of the form to explain why you are filing Form 1040X. Generally, to claim a refund, Form 1040X must be filed within 3 years from the date of your original return or within 2 years from the date you paid the tax, whichever is later. Returns filed before the due date (without regard to extensions) are considered filed on the due date.
Please Note: Your state tax liability may be affected by a change made on your federal return. For information on how to correct your state tax return, contact your state tax agency.
