What Is IRS Notice CP63?

IRS Notice CP63 is a delayed tax refund notice. It explains that the IRS is holding your tax refund due to unfiled returns from prior years because they believe you may owe taxes for those periods.

How do I find out which year the IRS is holding my refund for?

Check the CP63 notice for the specific tax years listed as unfiled. If the letter is unclear, you can sign into your IRS Online Account to view your 'Record of Account' or call the IRS at 800-829-1040.

Will filing late returns release my refund?

Yes. Once you file the delinquent returns and they are processed, the IRS will release the refund. Note that if you owe taxes for the prior years, the IRS will first apply the held refund to that debt and send you any remaining balance.
