Collection Due Process Hearing: Your 30 Days, Your Tax Court Rights

A Collection Due Process hearing is the strongest appeal right in IRS collections: a timely request prohibits the levy, suspends the 10-year collection clock, puts your case in front of Appeals, and ends with a determination you can take to U.S. Tax Court. It is also perishable — it exists only inside a 30-day window attached to two specific notices, and everything on this page flows from protecting that window. The form itself is a separate skill, covered line by line in the Form 12153 walkthrough; this page owns the right and the hearing.

General information, not tax advice. A CDP deadline is jurisdictional — postmark discipline matters. If your 30 days are running, file the request first and perfect the arguments after.

The two notices that carry CDP rights

CDP attaches to exactly two events (IRS CDP FAQs):

• A Notice of Federal Tax Lien filing — Letter 3172, under §6320. The 30-day request period runs from the end of the 5-business-day period after the NFTL is filed.
• A Final Notice of Intent to Levy — LT11, Letter 1058 or CP90, under §6330. The notice itself starts the 30 days. (What those letters mean and demand, step by step: the Letter 1058 response guide; CP504, by contrast, carries no CDP rights — see the CP504 response guide.)

You get one CDP hearing per tax period per notice type. A timely request is judged by the postmark rule — timely mailing is timely filing.

What a timely request does immediately

• Levy is barred. For the noticed periods, the IRS may not levy while the hearing and any Tax Court review are pending (§6331(k)).
• The collection statute suspends. The 10-year CSED clock stops from the request until the determination becomes final — the IRS cannot run out the clock on you mid-appeal, and you should understand that the suspension also extends the IRS’s remaining collection time afterward.
• Your case leaves Collection. An Appeals officer with no prior involvement in the case conducts the hearing — usually by phone, though correspondence and in-person conferences are available.

What Appeals actually weighs (§6330(c))

The hearing is not a general negotiation. By statute, Appeals must:

1. Verify that the legal and procedural requirements for the levy or lien were met — assessment, notice and demand, the notice itself.
2. Consider the issues you raise — which is why the request must state them; issues not raised are generally off the table later, including in Tax Court.
3. Hear a liability challenge only if you had no prior opportunity to dispute the amount (§6330(c)(2)(B)) — no second bite after a notice of deficiency or a prior CDP hearing on the same liability.
4. Consider spousal defenses and collection alternatives — installment agreement, offer in compromise, currently not collectible placement (the CNC cluster covers that destination).
5. Balance the government’s need for efficient collection against your legitimate concern that the action be no more intrusive than necessary.

Mechanics in one paragraph: request the hearing on Form 12153, sent to the hearing-request address printed on the CDP notice (not the payment address), within the 30 days, with the notice’s periods and your reasons — the walkthrough covers every line, the equivalent-hearing checkbox trap, and the proof-of-mailing standard.

After the hearing: Notice of Determination, then Tax Court

Appeals issues a Notice of Determination sustaining or releasing the proposed action. From that notice you have 30 days to petition the U.S. Tax Court (§6330(d)) — the only judicial review in the CDP system, and the reason CDP outranks every other collection appeal. Collection remains suspended while a timely Tax Court case is pending.

Missed the 30 days? The equivalent hearing — and what it costs

A request filed within 1 year of the notice (for liens: 1 year plus the 5 business days after filing) still gets an equivalent hearing: Appeals considers the same kinds of issues, but you receive a Decision Letter instead of a Notice of Determination, and you lose three things, bluntly: no levy prohibition during the process, no suspension of the collection statute, and no Tax Court review at the end. An equivalent hearing is a fallback, not an equivalent — file inside 30 days whenever the window is open.

One exception to the notice-first pattern: under §6330(f), in jeopardy situations, state-tax-refund levies and disqualified employment tax levies, the IRS may levy first and grant CDP rights afterward. A levy that arrived without a preceding final notice is not automatically void — check whether an exception applies before building your challenge on the missing notice. Where the whole sequence fits together is mapped on the levy timeline and the prevention page of this cluster.

CDP vs CAP, in one look

CAP wins on speed and availability; CDP wins on everything else when its window is open. The full comparison lives on the CAP page.

Frequently asked questions

What is a Collection Due Process hearing? Your statutory right (IRC §§6320, 6330) to have an independent IRS Appeals officer review a lien filing or a proposed levy before it proceeds: Appeals verifies the IRS followed the law, considers your issues and collection alternatives, applies a balancing test, and issues a Notice of Determination you can petition to Tax Court within 30 days (IRS CDP FAQs).

How do I request a Collection Due Process hearing? By written request — normally Form 12153 — sent to the address on the CDP notice within 30 days of the notice date, identifying the tax periods, checking the lien or levy basis, and stating your reasons and the alternative you want. Timely mailing counts as timely filing; certified mail with return receipt is the proof standard. The line-by-line mechanics are in the Form 12153 walkthrough (practitioner walkthroughs and the CDP Deskbook agree on the address trap: never the payment address).

What happens if I miss the 30-day CDP deadline? You can still request an equivalent hearing within 1 year of the notice, and Appeals will hear the same kinds of issues — but there is no bar on levy action, no suspension of the 10-year collection statute, and no Tax Court review of the resulting Decision Letter. The 30-day rights do not come back.

Can I dispute the amount I owe at a CDP hearing? Only under limited circumstances: Appeals may consider the underlying liability solely if you had no prior opportunity to dispute it — for example, you never received a notice of deficiency and never had a previous CDP hearing on that liability (§6330(c)(2)(B); IRS CDP FAQs). If you already had your chance, the hearing is confined to the collection action itself and to alternatives.
