A CP2000 is the IRS telling you that the income figures on your return do not line up with the figures third parties sent them. Those third parties are employers, banks, brokerages, and payment platforms filing W-2s, 1099s, and 1099-Ks.
It is not a bill and it is not an audit. It is a proposal. The IRS is showing the math it would apply if the third-party numbers are right and yours are not, and it gives you a window to reply before that math becomes final.
The envelope usually contains a summary page, a detailed comparison of what you reported against what was reported about you, a proposed tax figure, and a response form with a checkbox for agreeing or disagreeing.

RE: Notice CP2000, Proposed Adjustment of $4,237.00, Tax Year 2024
To Whom It May Concern:
I am writing in response to the CP2000 notice dated [Date], which proposes additional tax of $4,237.00 for tax year 2024. After reviewing the third-party information referenced in the notice, I disagree with the proposed adjustment in full.
1. The Form 1099-K reflects gross transaction volume, not taxable income. The $18,400 referenced includes customer refunds, sales tax collected and remitted, and platform fees that were already accounted for on Schedule C, Line 2 and Line 10.
2. Supporting documentation is enclosed. Attachment A reconciles the 1099-K total to the gross receipts reported on the filed return, line by line.

It is a notice showing that income reported to the IRS by a third party does not match income on your filed return. The IRS proposes what the tax would be if its figures are correct and asks you to agree or disagree.
The response date is printed on the first page of the notice and is commonly 30 days from the notice date. Our tool reads that date off your specific notice and puts it at the top of your summary.
When no reply arrives by the printed date, the IRS typically moves forward with the proposed figures and issues a Notice of Deficiency, which starts a separate process with its own deadline.
Yes. A CP2000 is designed to be answered by the taxpayer, usually with a written explanation and supporting documents. Our tool drafts that written response from the numbers on your notice.
It is a proposal rather than a final bill, but it carries a deadline and the proposed amounts can become final without a reply. Most people who receive one are dealing with a single mismatched income document.
The notice itself is not reported to credit bureaus. It is correspondence between you and the IRS about a tax year.
An early income mismatch inquiry that comes before a formal CP2000.
