What Is a CP2000 Notice?

A CP2000 notice is not a bill but a proposal from the IRS indicating that the income, credits, or deductions you reported do not match the information they have. This often happens when employers, banks, or other payers report income or payments differently than what you included on your tax return.

Steps to Respond to a CP2000 Notice

Responding promptly and accurately is crucial. Here’s how to handle it:

  1. Review the notice carefully

    Compare the IRS’s information with your tax return and supporting documents like W-2s, 1099s, and bank statements.

  2. Agree with the proposed changes

    If the IRS’s information is correct, sign the response form included with the notice and return it. Pay any additional tax owed by the due date to avoid penalties and interest.

  1. Disagree with the proposed changes

    If you believe the IRS is wrong, gather evidence such as corrected forms or receipts. Write a clear explanation and include copies of supporting documents. Mail your response by the deadline.

  2. Request a payment plan if needed

    If you cannot pay the amount owed immediately, contact the IRS to discuss installment options.

  1. Keep copies of all correspondence
