If you paid your tax bill but the IRS still sent you a CP14 notice, please be aware that due to their backlog, they may not have registered your proof of payment yet and you might receive a second notice. Also, make sure funds remain available and don’t cancel any check you sent.
A CP14 notice means that you owe money on unpaid taxes. In this case, it's generally because a payment is missing or hasn't been paid in full. Check your payment records, like bank transactions and canceled checks, to make sure that you or the IRS didn't miss anything.
If you agree with the changes the IRS made, you'll need to:
- Pay the amount owed by the date on the notice (see the electronic payment options). If you can't pay the full amount you owe, you can make payments.
- Correct the copy of your tax return that you keep for your own records.
If you don't agree with the changes, contact the IRS within 60 days from the date of your notice. You can do this:
- By telephone—the number is on your notice
- By certified mail—include a copy of the notice and allow 30–60 (or more) days for a resolution
