What Is a CP3219A Notice?
A CP3219A is a formal legal document from the Internal Revenue Service — not a collection letter, not a reminder, and not a request. It is the Statutory Notice of Deficiency, one of the most legally significant documents the IRS can send to a taxpayer. It formally proposes an additional tax assessment and marks the end of the administrative process between you and the IRS regarding the tax year or years in question.
The notice is printed on official IRS letterhead and will typically be several pages long. It will show your name, address, Social Security number, and the tax year or years being addressed. It will specify a dollar amount the IRS is proposing to add to your tax liability — an amount that includes additional tax, accuracy-related penalties in many cases, and interest calculated to the notice date. It will also notify you formally of your right to challenge the proposed assessment in the United States Tax Court.
Understanding what the CP3219A is — and what it is not — is the first step in responding to it correctly. It is not a bill for a balance you already owe. It is not a notice that levy action is beginning. It is a proposal, combined with a legal mechanism that gives you specific rights you do not have at any other stage of the IRS process.
Why Did You Receive This Notice?
The CP3219A is not sent randomly or to taxpayers who simply owe a balance. It is issued when the IRS has proposed a specific change to your tax return — typically through the automated underreporter process or through an audit examination — and that proposed change was either disputed, ignored, or left unresolved through the earlier stages.
The most common paths to CP3219A include an ignored CP2000 where the IRS identified income that appeared on a third-party form but not on your return; a disputed CP2000 that was not resolved in your favor after your response; an audit that concluded without you signing the Revenue Agent's proposed adjustment; and in some cases, a prior notice sent to an old address that was never received.
What Is Physically on the Notice?
The CP3219A package contains several distinct sections.
The deficiency amount. The most prominent figure — a specific dollar amount per tax year representing the additional tax the IRS proposes to assess. This amount does not currently exist as a balance on your account. It is a proposed charge that becomes real only if the legal window closes without a Tax Court petition or a signed agreement.
The tax year or years covered. A single CP3219A can address multiple tax years simultaneously. Each year will be listed with its own proposed deficiency amount.
The explanation of proposed changes. This section breaks down what the IRS changed on your return and why. It references specific lines on your original return, the amounts you reported, the amounts the IRS believes are correct, and the basis for the difference.
The formal notification of Tax Court rights. The CP3219A must by law inform you of your right to petition the United States Tax Court within the applicable window. This section explains what Tax Court is, how to petition it, and the filing fee.
The agreement form. If you agree with all or part of the proposed additional tax, Form 5564 (Notice of Deficiency Waiver) is included for you to sign and return to formally accept the assessment.
What the Legal Window Means for Your Situation
The CP3219A triggers a period of time — set by statute in the Internal Revenue Code — during which the IRS is legally prohibited from assessing the proposed additional tax. The proposed amount cannot be collected, cannot be levied, and does not appear as a balance on your account during this window.
The window is 90 days for taxpayers in the United States and 150 days for taxpayers outside the U.S. The window begins from the date printed on the notice — not the date you receive it.
During this window, you have time to review the proposed assessment, gather documentation, consult a professional, and decide whether to accept, negotiate, or challenge. This is a protected window that exists nowhere else in the IRS collection process.
What Happens After the Window Closes Without a Petition?
Once the window passes without action, the IRS formally assesses the proposed additional tax. The amount — plus accumulated penalties and interest dating back to the original return due date — becomes an official balance on your account.
The IRS then issues balance-due notices beginning with a CP14, proceeding through the standard collection sequence. The option to challenge the assessment in Tax Court without first paying is permanently closed. The only judicial avenue remaining after assessment is to pay the full balance, file a claim for refund, and then sue in U.S. District Court — a substantially more expensive process.
The Relationship Between CP3219A and IRS Appeals
Many taxpayers who receive a CP3219A do not realize that filing a Tax Court petition frequently leads to an IRS Appeals review before any actual Tax Court proceeding. Appeals officers approach cases from a settlement perspective and have authority to settle cases for amounts different from the full proposed deficiency. Cases at the Appeals level are frequently resolved for less than the amount proposed in the CP3219A — sometimes significantly less — without ever going before a Tax Court judge.
Who Receives CP3219A Most Often?
Taxpayers who received a CP2000 and did not respond are the most common recipients. Self-employed individuals with unreported 1099 income are the second most common group. Taxpayers who went through an audit without signing the Revenue Agent's proposed adjustment also commonly receive CP3219A when the IRS formalizes the examination.

Frequently Asked Questions
Can the IRS send a CP3219A without a prior audit?
Yes — and this is the most common scenario. The automated underreporter program does not involve a human auditor. The CP3219A can arrive after the CP2000 process without any audit ever occurring.
What happens to interest and penalties during the legal window?
Interest does not accrue on a proposed deficiency during the window — only on assessed tax. However, when the tax is assessed after the window closes, interest is calculated from the original due date of the return. The interest component can be substantial even though it was not actively accumulating during the window.
Can I still negotiate with the IRS after receiving a CP3219A?
Yes. The IRS Office of Appeals can review your case, and this review often happens after a Tax Court petition is filed. Direct negotiation with the original examiner is generally not available at this stage, but the Appeals process remains open.
What if I agree with part of the proposed assessment but not all of it?
You can file a Tax Court petition specifically disputing the portions you disagree with while conceding the portions you agree with. The petition does not require you to contest every item — you can challenge selectively.
Does receiving CP3219A mean I will face criminal charges?
No. The CP3219A is a civil tax notice. Criminal tax enforcement is a separate process involving willful tax evasion or fraud. The vast majority of CP3219A recipients have civil compliance issues resolved through civil processes.
