IRS CP2000: A Proposed Change, Not a Final Bill

The IRS compares filed returns with Forms W-2, 1099, K-1, and other information returns. CP2000 explains a proposed change when those records appear not to match.

The proposal can overstate tax when gross stock or crypto proceeds are treated without cost basis, income appears in a different location on the return, a payer used the wrong taxpayer identification number, or the same income was reported twice.

If the IRS is correct, the response should still check whether its calculation includes every connected expense, credit, withholding payment, and penalty issue. If it is wrong, the response should explain each disputed item and attach records that let a reviewer reproduce the correction.

If the proposal has already become a statutory notice of deficiency, the deadline rules change. See our CP3219A response guide.

Read the current IRS explanation for this notice at IRS.gov. The instructions and address printed on your own letter control.

1. 1Compare every proposed item with the filed return and information statements.
2. 2Obtain wage-and-income records to see exactly what third parties sent the IRS.
3. 3Reconstruct cost basis, business expenses, withholding, or corrected forms omitted from the proposal.
4. 4Choose whether you agree, partially agree, or disagree and explain each line separately.
5. 5Submit the signed response through a method allowed on the notice and keep proof.

Agree only after confirming the arithmetic and the complete tax effect. Partial agreement is appropriate when some information items are correct and others need adjustment.

When you disagree, identify the payer, form, amount shown by the IRS, amount that should be used, and supporting exhibit. If identity theft or a payer error is involved, follow the notice-specific documentation process.

CP2000 representation is most valuable when the proposed tax is material or the response requires reconstructing transactions rather than sending one missing form.

• The proposal involves securities, crypto, K-1s, self-employment, or multiple states.
• The proposed tax or penalty is significant.
• The information belongs to another person or reflects identity theft.
• A prior response was rejected or CP3219A has arrived.
• You want a CPA to reconcile the proposal and handle authorized contact.
