CP3219A Notice
The CP3219A is an IRS Notice of Deficiency — commonly called the '90-day letter' — informing you that the IRS has determined you owe additional taxes following an audit or review. You have 90 days to petition the U.S. Tax Court to challenge the IRS's findings. Missing this deadline gives up that right permanently.
Why Did You Receive This Notice?
You received a CP3219A because the IRS audited or reviewed your tax return and determined that you owe more taxes than were originally reported. This notice formally asserts the IRS's position and starts the legal clock. Common triggers include an IRS examination of income discrepancies, disallowed deductions, unreported income found through matching with third-party records, or an audit examination of a specific return.
What Does this Mean for You?
The CP3219A is one of the most legally significant notices the IRS issues. It is a formal legal document asserting a tax deficiency. The notice explains the IRS's proposed changes, the resulting tax increase, and any penalties. Crucially, it gives you 90 days (or 150 days if you are outside the United States) to petition the U.S. Tax Court to dispute the findings. You cannot go to Tax Court after this deadline — your only remaining option would be to pay and then sue for a refund in federal district court.
What Happens If You Ignore It?
Your Options
- Petition the U.S. Tax Court: File a petition with the Tax Court within 90 days to dispute the IRS's findings without having to pay first. This is often the most advantageous path and is available to individuals at relatively low cost.
- Agree and pay: If you believe the IRS is correct, you can sign the agreement form enclosed with the notice and pay the deficiency. This closes the matter without court involvement.
- Request an IRS Appeals conference: Before or after petitioning Tax Court, you may be able to resolve the matter through an IRS Appeals Officer, who can settle disputes based on the hazards of litigation.
Step-By-Step: What To Do Next
Step 1: Note the date on the CP3219A immediately — the 90-day countdown starts from that date.
Step 2: Review the IRS's proposed changes carefully and gather your documentation.
Step 3: Consult a tax professional or tax attorney as soon as possible — this is not a notice to respond to on your own.
Step 4: Decide whether to petition the Tax Court, agree with the IRS findings, or seek an IRS Appeals conference.
Step 5: If petitioning Tax Court, file the petition before the 90-day deadline. The Tax Court has a small case division (S-case procedure) for amounts under $50,000 that is less expensive.
Step 6: If agreeing, sign and return the agreement form with payment.
Can You Handle this Yourself?
While technically you can represent yourself in Tax Court, the CP3219A involves enough legal and procedural complexity that professional representation is strongly recommended. A tax attorney or enrolled agent familiar with IRS exam procedures and Tax Court practice can significantly improve the outcome. At minimum, get a professional consultation before the 90-day window closes.

FAQ
Q: Do I have to go to Tax Court after receiving a CP3219A?
A: No. You can agree with the IRS and pay, or you can seek resolution through IRS Appeals. Petitioning Tax Court is an option — not a requirement — but it is the primary legal tool for disputing the deficiency without paying first.
Q: What happens if I miss the 90-day deadline?
A: The IRS will formally assess the deficiency and begin collection. Your right to challenge the deficiency in Tax Court without paying is permanently lost. Your only remaining option is to pay in full and then sue in federal district court for a refund.
Q: How much does it cost to petition the U.S. Tax Court?
A: The filing fee for Tax Court is $60. For cases involving less than $50,000 per tax year, the simplified Small Tax Case (S-case) procedure is available, which is less formal and less expensive than full Tax Court proceedings.
