We made changes to your return because we believe there’s a miscalculation. As a result, you are due a refund.
What you need to do
You don't need to do anything. If you haven't received it already, you should receive a refund of the overpaid amount within 4-6 weeks as long as you owe no other taxes or debts we are required to collect.
Your deadline
Answer by the date printed on your notice. If there is no date, answer as soon as you can, and call the number on the notice if you need more time.
What to check before you answer
You have 60 days to disagree
If you disagree with the change and ask in writing within 60 days of the notice date, the law requires the IRS to reverse it. If the IRS still disagrees, it must then use the regular process, which keeps your appeal rights.
Is this letter really from the IRS?
The IRS writes first by mail. A real letter shows a notice or letter number, your name and part of your tax ID number. The IRS does not ask for payment by gift card, crypto or wire transfer. If in doubt, sign in to your IRS online account, where many notices are listed.
You may want to
- Compare the figures on the notice with your tax return.
- If you agree with our changes, correct the copy of your tax return that you kept for your records.
- Complete and send us a Form 2848, Power of Attorney and Declaration of Representative PDF , to authorize someone (such as an accountant) to contact us on your behalf.
