What Is a CP2000 Notice?

A CP2000 is generated by the IRS Automated Underreporter (AUR) system when information returns (W-2s, 1099s, brokerage statements, K-1s, etc.) do not match your filed tax return.

It is a proposed adjustment, not an audit and not a levy notice. The IRS is asking you to either:

• Agree with the proposed changes

• Or explain why the proposed adjustment is incorrect

No tax has been officially assessed yet at this stage.

What Typically Triggers a CP2000?

Common triggers include:

• Missing 1099 income

• Brokerage reporting mismatches

• Incorrect cost basis reporting

• Duplicate income entries

• Schedule C income discrepancies

• Cryptocurrency reporting mismatches

• K-1 income inconsistencies

CP2000 notices are focused specifically on third-party reporting discrepancies.

Your Deadline to Respond

Most CP2000 notices provide approximately 30 days to respond.

If no response is submitted:

• The IRS may assess the proposed tax

• Interest begins accruing

• Penalties may be added

• A balance due notice (CP14) will follow

Responding within the deadline preserves your ability to explain or correct the proposed adjustment.

This Is Not the Same As…

A CP2000 notice is not:

• CP504 (Intent to Levy)

• CP90 (Final Levy Notice)

• A 90-Day Statutory Notice of Deficiency

• A refund review notice (CP75)

CP2000 is a pre-assessment proposal based on information matching.

What the IRS Can and Cannot Do at This Stage

At the CP2000 stage, the IRS can:

✔ Propose additional tax

✔ Request documentation

✔ Ask for written explanation

At this stage, the IRS cannot:

✘ Levy wages

✘ Freeze bank accounts

✘ File a tax lien

✘ Seize property

Collection actions occur only after assessment.

Typical Documentation Required

CP2000 responses often require:

• Corrected income schedules

• Brokerage transaction statements

• Cost basis calculations

• Amended calculations

• Written explanation addressing each discrepancy

• Supporting forms or worksheets

Clear organization and structured response formatting reduce confusion and processing delays.

Common Mistakes

• Ignoring the notice

• Sending incomplete brokerage pages

• Failing to address each line item

• Assuming IRS data is automatically correct

• Submitting emotional explanations without documentation

• Missing the response deadline

What Happens If You Ignore a CP2000?

If no response is submitted:

CP2000 → Tax Assessment → CP14 Balance Due → CP504 → CP90

Escalation shifts the issue from proposed adjustment to active collection.
