What You Should Know about Filing Amended Tax Returns

Q: I just realized that I could have claimed a tax credit this year, but I’ve already filed my return. Is there anything I can do?
A: Yes. You can file an amended return using IRS Form 1040X. If you are eligible to claim a credit, or perhaps a deduction that reduces your tax bill, you should do so.
 
Q: What if I’ve made a mathematical error on the tax return I already submitted?
A: Generally, you do not need to file an amended return to correct mathematical errors because the IRS will automatically make such corrections and send you a printed notice. Also, amended returns should not be filed for forgotten tax forms such as W-2s or schedules; the IRS normally will mail you a notice asking you for any such forms if they are needed.
 
Q: What if I’ve forgotten to report income?
A: If you’ve forgotten to report income, you should file an amended return as soon as possible. The sooner you correct such a mistake, the lower any possible penalties and interest you may owe will be. Reporting the additional income on a 1040X form could save you money in the long run.
 
Q: Can I submit a 1040X form electronically?
A: No. Form 1040X must be filed using the paper form and mailed in. If you are amending more than one tax return, each 1040X form should be mailed in a separate enveloped addressed to the appropriate IRS processing center.
 
Q: How much time do I have to file an amended return?
A: An amended return must be filed within three years from the date of the original return or within two years from the date taxes were paid, whichever is later.
 
Q: How long will it take the IRS to process my amended return?
A: According to the IRS, it generally takes between eight and 12 weeks to process an amended return.
 
Q: Where can I find more information?
A: For more information about amended returns or to print a copy of Form 1040X, go to www.irs.gov and click on the link to Forms and Publications, or visit the IRS YouTube channel: www.youtube.com/watch?v=JUjC0avoZ_I.
