If you discover an omission or error made on your already filed tax return, you may need to file an amended return. Here are some IRS tips for amending returns.
- Use Form 1040X. You must file a paper amended return; this form can’t be e-filed.
- File an amended return to correct errors or change your original filing.
- Don’t file an amended return to correct math errors or to attach forms you forgot to attach originally. The IRS will mail a request for the forms and will automatically correct math errors.
- You generally have three years from the original filing date to file an amended return.
- If you’re filing for multiple years, you must file a separate Form 1040X for each year.
- If you’re due a refund from your original filing, wait until you’ve received the original refund before you file Form 1040X for an additional refund.
- If you owe more tax with Form 1040X, pay it as soon as possible to avoid added interest and penalties.
- You can track the status of your filed Form 1040X with the IRS’s “Where’s My Amended Return?” tool at www.irs.gov
