What Is IRS Notice CP2000?
The CP2000 notice is sent when the IRS’s records (such as W-2s, 1099s, or other third-party info) don’t match the income or information on your tax return.
It’s part of the IRS’s Automated Underreporter (AUR) program.
⚠️ Important:
CP2000 is not a bill, and it’s not an audit — but it may propose additional tax, interest, or penalties based on the difference.
Why Did You Receive a CP2000?
The most common reasons include:
- You forgot to report a 1099-INT, 1099-DIV, or 1099-B from your bank or investment account
- You left off a W-2 from a part-time or seasonal job
- You reported gross income instead of net (or vice versa)
- There was a mismatch in capital gains or stock sale proceeds
Even simple data entry errors can trigger the notice.
What’s Inside the CP2000?
When you open the letter, here’s what you’ll see:
- The difference between your return and third-party information
- Proposed changes to your return
- The tax, interest, or penalties the IRS believes you owe
- Instructions for how to respond by mail or online
- A response deadline (usually 30 days)
📎 Tip: Don’t ignore the deadline — even if you disagree, you must respond.
How to Respond to CP2000 (Step-by-Step)
Step 1: Review the Notice Carefully
Read every section and compare it to:
- Your original return (Form 1040)
- Your W-2s, 1099s, and other income docs
- Brokerage statements or crypto records (if applicable)
Step 2: Decide If You Agree or Disagree
✅ If You Agree:
- Sign the agreement form in the notice
- Mail the response to the IRS using the envelope provided
- Pay the proposed amount (online or by check)
❌ If You Disagree:
- Don’t sign the agreement form in the notice
- Attach a written explanation and supporting documents
- Clearly show why the IRS is mistaken (ex: amended 1099, corrected broker statement)
- Mail everything before the deadline
- If you need additional time to respond, you can request an extension by mail or fax or call number listed in the notice
📌 Tip: If you need help understanding the IRS math, use Form 1040-X as a comparison, or talk to a tax professional.
Frequently Asked Questions
What should I do if I think someone else is using my social security number?
If you recieve a notice from the IRS and you suspect someone is using your social security number or that your identify has been stolen, respond immediately to the notice.
You can call the number provided, write to the address or fax to the fax number shown on the notice.
What Happens If You Ignore It?
Bad news: If you don’t respond, the IRS will assume you agree, finalize the changes, and send you a bill.
Even if you can’t pay right away, it’s better to respond and set up a payment plan later than to ignore it.
If You Miss a 1099-NEC
Imagine you did some freelance work, got paid $4,500, and received a 1099-NEC — but forgot to include it on your return.
The IRS sees this because the company also sent them a copy. That triggers a CP2000, showing underreported income and proposing additional tax.
In this case, you’d sign the agreement, send payment, and fix it for next time.
Where to Pay If You Agree
Pay directly at IRS.gov/payments using:
- Direct Pay (from your bank)
- Credit or debit card
- Payment plan (Installment Agreement)
Include your SSN, tax year, and notice number CP2000 in any mailed checks.
Watch Out for Scams
CP2000 notices are sent by mail only. If you get a CP2000 by email, text, or phone call — it’s a scam.
