If you discover an error after your return has been mailed, you may
need to amend your return. The service center will usually correct errors
in math or request forms (such as W-2's) or schedules left
out. In these instances, do not amend your return!
However, do file an amended return if any of the following
were reported incorrectly:
- your filing status
- your total income
- your deductions or credits
Use Form 1040X (PDF), Amended U.S. Individual
Income Tax Return, to correct a previously filed Form 1040 (PDF), Form 1040A (PDF), Form 1040EZ (PDF), or TeleFile return. [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 2001, you should file Form 1040X and pay the tax by April
15, 2002.
Be sure to enter the year of the return you are amending at the top of Form
1040X. The form has three columns. Column A is used to show original
or adjusted figures from the original return. Column C is used to show the
correct figures. The difference between the figures in Columns A and C is
shown in Column B. There is an area on the back of the form where you explain
the specific changes being made on the return and the reason for each change.
If the changes involve another schedule or form, attach it to the 1040X.
For example, if you are filing a 1040X because you have a qualifying
child and now want to claim the Earned Income Credit, you must attach a Form 1040 Schedule EIC (PDF) to show the qualifying person's
name, year of birth, and social security number.
Generally, to claim a refund, Form 1040X must be received within
3 years from the date you filed your original return or within 2 years from
the date you paid the tax, whichever is later.
If you are filing more than one amended return, be sure to mail each in
a separate envelope to the service center for the area in which you live.
The
Instructions for Form 1040X list the addresses for the
service centers.
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.
