You Received an IRS CP2000 Notice: What It Means and Your Response Options
A CP2000 is not a bill and not an audit. It is an IRS notice proposing changes because amounts reported to the IRS by employers, banks, or brokers do not match what was on your return. You can agree, partially agree, or disagree, and you respond by the deadline on the notice — ignoring it is what turns a proposal into an assessment.
A CP2000 notice causes a lot of alarm that is often unwarranted. Understanding what it actually is makes the response straightforward.
What a CP2000 actually is
The IRS receives copies of income documents about you — W-2s, 1099s, brokerage statements. When the totals on those documents do not match your filed return, an automated system generates a CP2000 proposing an adjustment. It is a proposal, not a final determination, and not the same as being selected for audit.
Your three response paths
| If you... | Then |
|---|---|
| Agree with the change | Sign and return the response form; arrange payment of any balance |
| Partially agree | Explain which items you accept and which you dispute, with documentation |
| Disagree | Respond in writing with evidence supporting your original return |
Why the deadline matters
The notice carries a response deadline, commonly about 30 days. If you do not respond, the IRS can move to formally assess the proposed amount, after which correcting it is harder. Even if you disagree, responding on time preserves your options. A representative can respond on your behalf and handle the correspondence.
Common causes of a mismatch
Frequent triggers include a forgotten 1099, securities sales reported without their cost basis (so the whole proceeds look like gain), and income reported under the wrong year. Many CP2000s shrink substantially once the missing context — like cost basis — is supplied.
Frequently asked questions
Is a CP2000 an audit?
No. It is an automated notice proposing changes from a document-matching discrepancy. It is not the same as being selected for an examination.
What happens if I ignore a CP2000?
The IRS can proceed to assess the proposed additional tax. Responding by the deadline, even to disagree, keeps your options open.
Can the proposed amount be reduced?
Often yes. Many CP2000s overstate the tax because they lack context, such as the cost basis of sold securities. Supplying documentation can lower or eliminate the proposed change.
