What Is a CP2000 Notice? A Plain-English Guide

What Is a CP2000 Notice?

A CP2000 is a notice from the IRS saying they believe you have unreported income. This is the most common IRS notice — you're not alone.

The IRS compares what you reported on your tax return with information they received from third parties like employers, banks, and investment companies. If the numbers don't match, they send a CP2000.

Why Did You Get This Notice?

Common triggers include:

• 1099 income you forgot to report (freelance work, interest, dividends)
• W-2 discrepancies between what your employer reported and what you filed
• Investment gains from stock sales or crypto transactions
• Retirement distributions you withdrew but didn't report

What Happens If You Ignore It?

If you don't respond within 30 days, the IRS will assume their proposed changes are correct and adjust your tax return accordingly. This could mean:

• Additional tax owed plus interest
• Penalties for underpayment
• A formal bill (CP14 notice) arriving next

What Should You Do?

1. Don't panic — a CP2000 is a proposal, not a final bill
2. Review the notice carefully — compare the IRS's numbers with your records
3. If you agree, sign and return the response form with payment
4. If you disagree, gather documentation and respond in writing within 30 days
5. Call the IRS at the number on your notice if you have questions
