← All IRS letters

What this letter means

The IRS finished reviewing your return and proposes changes. You can agree or appeal.

Why you probably got it

An audit by mail is wrapping up.

Your deadline

Respond within 30 days of the letter date.

What to do next

  1. Review the report of proposed changes.
  2. If you agree, sign and return it.
  3. If you disagree, send more proof or request an Appeals conference before the deadline.
Scam check: The IRS starts contact by mail. It will never demand payment by gift card, wire transfer, or cryptocurrency, or threaten immediate arrest. Pay only at IRS.gov or by check to the U.S. Treasury, and confirm any phone number at IRS.gov before calling.

This is general information, not legal, tax, or financial advice for your specific situation. Every case is different. Always check the dates and amounts printed on your own documents.
