IRS CP2501: Income Mismatch: Initial Contact

Act soon

← All IRS letters

What this letter means

The IRS found a difference between your return and reported income and wants an explanation.

Why you probably got it

Third-party forms do not match what you reported.

Your deadline

Respond by the date on the notice.

What to do next

  1. Review the items listed.
  2. Send an explanation and documents if your return was correct.
  3. If you made a mistake, the IRS may follow up with a CP2000.
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.
