The latest date, by law, you can claim a credit or federal income tax refund for a specific tax year is generally the later of these 2 dates: 3 years from the date you filed your federal income tax return, or 2 years from the date you paid the tax. This time period is called the Refund Statute Expiration Date (RSED). If you filed your return before its due date, the IRS considers it filed on the due date. If you had income tax withheld or paid estimated tax during the year, we consider those payments to have been made on the return due date. How much credit or refund you can receive The amount of credit or refund you can receive depends on when you file your claim. You file a claim within 3 years from when you file your return Your credit or refund is limited to the amount you paid during the 3 years before you filed the claim, plus any extensions of time you had to file your return. You file a claim after 2 years from when you paid the tax Your credit or refund is limited to the amount you paid within the 2 years right before you filed your claim. When you didn't file a claim within the 3-year or 2-year expiration dates You can't get a credit or refund if you don't file the claim within 3 years of filing your original return, or 2 years after paying the tax, whichever is later, unless you meet an exception that allows you more time to file a claim. Exceptions to the 3-year/2-year expiration dates You may have more time to file a claim for credit or refund than the 3-year/2-year rules if you: Agree with the IRS in writing to extend the time limit to assess tax: The time limit is specified in your agreement, plus 6 months, to claim a credit or refund. There may be additional limits on the amount of credit or refund you can claim based on any limitations on the IRS's ability to assess tax, as shown in the written terms of your signed agreement. Are affected by a Presidentially declared disaster: You may have up to 1 more year to claim a credit or refund.
