Respond to CP2000 Notice
Verify income discrepancies and build an item-by-item response to the IRS underreporter notice.
The CP2000 is not a bill — it is a proposal. But ignoring it turns it into an assessment. This workflow helps you verify each discrepancy against your actual income documents, agree where the IRS is right, dispute where the IRS is wrong, and produce a response that the IRS can process efficiently.
The CP2000 is the IRS's Automated Underreporter (AUR) program notice. It proposes changes to your tax return based on income the IRS believes was underreported — typically because a 1099 or W-2 doesn't match your return. You have 30 days to respond. This workflow parses the notice, extracts each discrepancy, matches it against your income documents, and builds an item-by-item response that agrees, disputes with evidence, or requests further review for each line item.
Who this is for: Taxpayers who received a CP2000 Notice of Underreported Income and need to respond within 30 days.
