Understanding the CP2000 Response Form (Form 5564)

Most CP2000 notices include a response form – commonly referred to as Form 5564. This form allows you to indicate whether you agree or disagree with the IRS’s proposed changes.

If you agree, the form can be used to confirm acceptance of the adjustments. If you disagree, it provides a starting point for submitting an explanation along with supporting documentation.
