IRS notice CP2000: proposed changes to your return

A CP2000 proposes changes to your tax return because income or payment information from employers, banks or others doesn't match what you reported.

For individuals · Based on the IRS's own explanation of this notice

Deadline: Reply by the date listed on your notice, or send an extension request if you need more time.

What this notice means

Third parties, like employers and financial institutions, sent the IRS information that doesn't line up with your return. The difference could raise your tax, lower it or leave it the same.

This isn't a bill. It explains the changes the IRS is proposing and the information it used. You may need to reply by the date listed.

Why you got it

What to do now

  1. Read the whole notice and compare the proposed changes with your return.
  2. Answer by the date on the notice. If it came with a response form, complete and sign it, mark whether you agree or disagree, and attach any records that back you up. If there's no form, do what the notice says.
  3. Send your reply by upload, which is the fastest way, or by fax or mail, as your notice explains.
  4. If you agree and there's nothing else to add, do what the notice says. No amended return is needed. If you also have income, credits or expenses that weren't on your return, send Form 1040-X marked 'CP2000' at the top with your response form.
  5. If you'll owe tax, pay what you can. Interest builds until the balance is paid. If you can't pay in full, you can apply for a payment plan or an offer in compromise.
  6. If you need more time, send an extension request using one of the reply options.

If you don't respond

If you don't reply or the mismatch can't be resolved, the IRS may send another notice and a bill. Without a reply or an agreement, it sends a Statutory Notice of Deficiency, such as a CP3219A, by certified mail.

Estimate the interest. Interest on extra tax runs from the return's original due date, compounded daily.

Questions people ask
