Tips for Taxpayers Who Need to Amend a Return
Taxpayers who discover they made a mistake on their tax returns after filing can file an amended tax return to correct it. This includes changing the filing status and dependents, or correcting income, credits or deductions. The instructions for Form 1040X, Amended U.S. Individual Income Tax Return, list more reasons to amend a return. Taxpayers should not file an amended return to fix math errors, because the IRS will correct those.
Here are some tips on how a taxpayer amends a tax return. Taxpayers should:
- Complete and mail the paper Form 1040X, Amended U.S. Individual Income Tax Return, to correct errors to an original tax return the taxpayer has already filed. Taxpayers can’t file amended returns electronically and should mail the Form 1040X to the address listed in the form’s instructions. However, taxpayers filing Form 1040X in response to a notice received from the IRS, should mail it to the address shown on the notice.
- Prepare Form 1040X. Many taxpayers find the easiest way to figure the entries for Form 1040X is to make the changes in the margin of the original tax return and then transfer the numbers to their Form 1040X indicating the year they are amending. Use the second page of Form 1040X in Part III to explain the changes.
- Know when not to amend. Aside from math errors, taxpayers also do not need to amend their return if they forgot to include a required form or schedule. The IRS will mail a request to the taxpayer, if needed.
- Use separate forms for each tax year. Taxpayers amending tax returns for more than one year will need a separate 1040X for each tax year. Mail each tax year’s Form 1040X in separate envelopes.
- Wait to file for corrected refund for tax year 2017. Taxpayers should wait for the refund from their original tax return before filing an amended return. It is okay to cash the refund check from the original return before receiving any additional refund.
- Pay additional tax. Taxpayers filing an amended return because they owe more tax should file Form 1040X and pay the tax as soon as possible. This will limit interest and penalty charges.
- File within three-year time limit. Generally, to claim a refund, taxpayers must file a Form 1040X within three years from the date they timely filed their original tax return or within two years from the date the person pays the tax – usually April 15 – whichever is later.
Track an amended return. Taxpayers can track the status of an amended return three weeks after mailing using “Where’s My Amended Return?” Processing can take up to 16 weeks
