IRS CP2000 Notice — What It Means and What To Do
Receiving an IRS CP2000 notice can feel overwhelming. This guide explains what the notice means, what the deadlines are, and what options exist for penalty relief.
Response Deadline
The IRS expects a response within 30 days (60 days if outside the US). Acting before this deadline preserves all relief options and prevents escalation to the next collection stage.
What This Notice Means
The IRS received information (W-2s, 1099s, etc.) from third parties that does not match what was reported on your tax return. The CP2000 is a proposed adjustment — not a bill — and may result in additional tax owed or, in some cases, a refund.

If you agree with all changes, sign the Response form and return it
If you partially or fully disagree, submit a signed statement with supporting documentation
Respond by the deadline to avoid automatic assessment and a Statutory Notice of Deficiency

Frequently Asked Questions
Is a CP2000 notice an audit?
No. A CP2000 is an automated underreporter inquiry, not a formal audit. The IRS matched third-party information returns against your filed return and found a discrepancy.
What happens if I do not respond to a CP2000?
The IRS will send a Statutory Notice of Deficiency (90-day letter), which assesses the proposed changes automatically. You then have 90 days to petition the Tax Court before the assessment becomes final.
Why does my CP2000 include income I already reported?
This can happen if income was reported on a different line of your return than where the IRS expected it, or if amounts were consolidated. Your response should explain where the income appears on your return.

Can the CP2000 result in a refund?
Yes. If the proposed adjustment includes additional deductions or credits, the result may be a refund rather than a balance due.
What documentation should I include in my response?
Include copies of relevant W-2s, 1099s, receipts, brokerage statements, or other records that support your position. Also include a clear written explanation.
Can I get the accuracy-related penalty removed?
The 20% accuracy-related penalty may be waived if you can demonstrate reasonable cause, such as reliance on a tax professional or a good-faith interpretation of the tax law.
How long does it take the IRS to process my CP2000 response?
Processing typically takes 60-90 days, though it can take longer during peak periods. You will receive a letter confirming the outcome.
