IRS CP2000 Notice: A Proposed Change, Not A Bill
Notice Instructions: The Date On Your Notice
A mismatch is a reason to reconcile the records. The proposal is not your final answer.
A CP2000 proposes a change because third-party income or payment information differs from your return. It is not a bill. Review each item and respond by the date on your notice, stating whether you agree or disagree and supplying the required supporting records.

Common Questions About CP2000
- Does A CP2000 Automatically Mean I Owe More?
- No. The proposed change may increase tax, decrease it, or leave it unchanged.
- Should I Automatically Amend My Return?
- No. If you agree and have nothing else to report, the IRS says an amendment is unnecessary. If the notice is correct and you have other income, credits, or expenses to report, follow its Form 1040-X instructions.
- What If I Disagree?
- Identify the disputed items and provide the supporting records requested by the notice. Respond by its deadline.
