The short answer

What should I do about a CP2000 notice?

A CP2000 means income or payments reported by others, like employers or banks, don't match your return. It is not a bill. It proposes changes, and you may need to reply by the date listed.

The difference may raise your tax, lower it, or not change it at all. The notice shows what the IRS used.

If you agree and have nothing else to report, follow the notice. You don't need to amend. If you have other income, credits or costs to add, send Form 1040-X with "CP2000" written on top.

If you don't reply, or the IRS can't fix the mismatch, you may get another notice and a bill.

Key facts

  • The reply date on the notice
  • Every Form W-2 and 1099 for that year
  • Your copy of the return
  • Prior years with the same issue
  • Whether someone used your name and Social Security number (send Form 14039)

Is a CP2000 an audit?

It is a mail review of income that doesn't match. Audits also start by mail. The IRS never starts an audit by phone.
