If you’ve received a CP2000 notice, one of the most common questions is: “What should I say in my response?”

This section provides example letters, templates, and writing guidance to help you prepare a clear and structured response to the IRS. Whether you agree, disagree, or partially agree with the proposed changes, using the right format and language can make your response easier to review and process.

Why Your Response Letter Matters

While the CP2000 process includes a response form (Form 5564), many situations also require a written explanation.

A well-prepared response letter can help:

• Clarify your position
• Explain discrepancies or corrections
• Provide context for supporting documents
• Reduce the likelihood of follow-up requests

The goal is not to argue, but to present accurate information in a clear and organized way that will be familiar to IRS examiners.

CP2000 Response Letter Examples

Below are examples based on the most common response scenarios.

If You Agree With the CP2000 Notice

If you agree with the IRS’s proposed changes, your response is usually straightforward. In some cases, a short confirmation letter may accompany your completed response form.

Example: CP2000 Response Letter Example (Agree)

If You Disagree With the CP2000 Notice

If you believe the IRS’s proposed changes are incorrect, your response should clearly explain why, supported by relevant documentation.

Example: CP2000 Dispute Letter Example (Disagree)
