Need More Time to File? Facts about Amended Returns

Taxpayers who need to change a return they already filed can file an amended return. Here are some tips every taxpayer should know about amending a federal return:

• To amend a return, use Form 1040X, Amended U.S. Individual Income Tax Return. The same form is used for 1040, 1040A and 1040EZ returns, and for e-filed returns.
• You should file an amended return if any of the following were reported incorrectly: filing status, dependents, total income, deductions or credits.
• You usually do not need to file an amended return for math errors - the IRS will make the correction for you. You also do not usually need to file an amended return because you forgot to include forms, such as W-2s or schedules - the IRS normally requests those forms from you.
• Be sure to enter the year of the return you are amending at the top of Form 1040X. Generally, you must file Form 1040X within three years from the date you filed your original return or within two years from the date you paid the tax, whichever is later.
• If you are amending more than one tax return, prepare a 1040X for each return and mail them in separate envelopes.
• If the changes involve another schedule or form, attach it to the 1040X.
• If you are filing to claim an additional refund, wait until you have received your original refund before filing Form 1040X. You may cash that check while waiting for any additional refund.
• If you owe additional tax for the year, you should file Form 1040X and pay the tax as soon as possible to limit interest and penalty charges. Interest is charged on any tax not paid by the due date of the original return, even if you filed an extension.
