Internal Revenue Service (IRS) Notice CP2000 & Response Form 26 U.S.C. § 6213(b) & IRM 4.19.3

Notice CP2000 & Response Form Instructions: Notice CP2000 Proposed Adjustment Defense & 1099 Matching Errors

“The IRS sent Notice CP2000 claiming I made $60,000 in unreported stock sales and demanding $18,000! In reality, I bought the stock for $58,000 and only made $2,000 profit! How do I stop this bill?”

Official Procedural Summary & Rules

CP2000 is a computer-generated proposal, not a final bill. If the IRS assumed your cost basis was $0, submitting Form 8949 with your broker trade confirmations will eliminate the proposed tax.

1. Never File Form 1040-X for a CP2000

Filing an amended return causes duplicate processing delays. Mail or fax your response directly to the specific AUR unit address listed on the CP2000 cover sheet.

⚠️ Administrative Traps & Rejection Triggers

If you fail to respond to Notice CP2000 within 30 days, the IRS will automatically issue a Statutory Notice of Deficiency (CP3219A), triggering a strict 90-day Tax Court deadline.
