I received a CP2000 notice from the IRS. Now what?

Updated May 11, 2026 by Robin Scott-Hutchens, EA

Getting an IRS CP2000 notice can feel alarming, but in many cases, it’s simply the IRS letting you know the income information it received (from employers, banks, brokerages, or other payers) doesn’t match what was reported on your tax return. The key is to stay calm, read the notice carefully, and respond by the deadline—whether you agree with the proposed changes or not.

 

What is a CP2000 notice?

A CP2000 is a notice proposing changes to your tax return. It’s commonly triggered when the IRS’s records of income items—such as wages, interest, dividends, stock sales, retirement distributions, or other payments—don’t line up with what was reported on the return. A CP2000 is not the same as a full IRS audit, but it does require your attention and a timely response.

 

Why did I receive a CP2000?

CP2000 notices typically happen because information reported to the IRS by a third party doesn’t match what was included on the tax return. This can occur for several reasons, including:
 

• Missing or incomplete reporting of income items (for example, a forgotten Form 1099).
• Stock or cryptocurrency transactions reported without properly reporting cost basis, which can make gains look larger than they are.
• Incorrect amounts entered on the return (typos, transposed numbers, or using the wrong form).
• Timing or reporting differences (for example, corrected forms or late-arriving tax documents).

First steps: what to do right away

• Take a breath and don’t ignore it. A CP2000 has response deadlines, and delaying can make the situation harder to resolve.
• Read the notice closely. Identify the tax year, the income items in question, and the IRS’s proposed changes.
• Gather your documents. Gather all the documents reported on your tax return (W-2s, 1099s, brokerage statements, K-1s, and any corrected forms).
• Compare the CP2000 to the documentation your tax return. Match each income item on the notice to the form(s) you received (W-2, 1099, brokerage/crypto statement, K-1) and compare these to what you reported on the return.
• Decide whether you agree, partially agree, or disagree. This determines what you’ll send back—payment and signed agreement if you agree, or a written explanation with supporting documents if you don’t. 
  • If you have an Audit Defense membership with TaxAudit, do not respond to the IRS. Contact us immediately so we can step in to review the notice and tax return and determine the next steps. 

Don’t miss the deadline

A CP2000 will list a response due date. Responding on time matters because delays can lead to the IRS finalizing the proposed changes and assessing additional tax, plus potential interest and penalties. Even if you need time to gather records, it’s important to follow the notice instructions and respond promptly.

 

When to get help

If you’re unsure how to interpret the notice, how to document your position, or how to calculate the right tax impact, consider getting help from a qualified tax professional. With TaxAudit, you don’t have to navigate the process alone. Enlisting the help of a tax professional who is familiar with navigating this type of situation can be invaluable and can relieve considerable stress.

 

CP2000 FAQ

Is a CP2000 an audit?

A CP2000 is a proposed adjustment based on matching information returns to your tax return. While it’s not the same as a full audit, it is an IRS notice you must address.

What happens if I don’t respond?

If you don’t respond, the IRS may finalize the proposed changes and send a bill. Responding by the due date helps you preserve your opportunity to agree, dispute, or clarify the items in question.

Can the IRS-proposed amount be wrong?

Yes. Some CP2000 proposals are based on incomplete information (for example, security sales proceeds reported without cost basis). That’s why comparing the notice to your records and responding with supporting documentation is so important.
