The CP31 means the IRS mailed your refund check, but it came back undeliverable. The post office couldn't deliver it because the address on file is wrong, you moved without forwarding mail, or there was another delivery issue. Your refund is waiting, but the IRS needs a current address to send it to.
How to Get Your Refund
Update your address with the IRS and request a replacement check. You can update your address by filing Form 8822 (Change of Address), calling the IRS at the number on the CP31, or updating your address through your IRS Online Account.
Once your address is updated, the IRS will reissue the check to your new address. Processing time is typically 4 to 6 weeks. If you want faster delivery, ask about direct deposit when you call.
Verify Your Address Is Current
The IRS uses the address on your most recently filed return. If you've moved since filing, the IRS may not have your current address. File Form 8822 every time you move. This is especially important if you're expecting refunds, correspondence, or notices.
Unclaimed Refunds
If you don't claim your refund, the IRS holds it. They don't send it to a state unclaimed property fund. The refund remains available indefinitely, but you must contact the IRS to claim it. There's no time limit on claiming a refund check that was issued but returned, unlike the three-year statute for claiming a refund that was never filed for.
If your refund check was returned, call the IRS at the number on the CP31 or call us at (813) 229-7100. We'll help you update your address and get your money.
