Received an IRS notice? Start with what it says.

Find the notice number and response date

Look for a CP or letter number, the tax year, the amount listed, and any deadline. These details help explain why the IRS contacted you. Keep every page of the notice and a copy of any response you send.

Check the information against your records

Compare the letter with your return, payments, and previous correspondence. If you disagree with a change, follow the notice’s instructions for responding. A balance-due letter and a request for documents can require different actions.

Explain any urgent concern when you call

Mention a deadline, levy notice, or other collection language at the start. Ask what can be reviewed, which documents are needed, and whether representation or a response is included in the proposed service.

If the letter says you owe tax

You can discuss payment help and whether other relief options warrant review. Keep the notice available even if you cannot pay the amount shown. Learn about payment arrangements.
