Which IRS collection notice did you get, and how much time do you have?

IRS collection notices arrive in a fixed sequence, and only some of them carry a legal deadline. The order for most individual accounts is CP14, CP501, CP503, CP504, then an LT11, Letter 1058 or CP90. That last group is the Final Notice of Intent to Levy and Notice of Your Right to a Hearing. It starts a 30-day window to request a Collection Due Process hearing, and after the 30 days the IRS can levy wages, bank accounts and Social Security without further warning.

Two other certified letters have their own clocks. Letter 3172 tells you a Notice of Federal Tax Lien has been filed and gives 30 days to request a hearing about the lien. A notice of deficiency (CP3219A or Letter 3219) is not a collection notice at all; it is the IRS proposing additional tax, and you have 90 days to petition the United States Tax Court before the tax is assessed.

The table below is the whole ladder. Find your notice number in the upper right corner of the letter.

If your situation is a balance you cannot pay rather than a dispute about the amount, our tax debt relief page lays out the options a hearing is meant to produce.

Why did the IRS send a certified letter?

Because the statute requires it. Section 6212(a) authorizes a notice of deficiency "by certified mail or registered mail." Sections 6320(a)(2) and 6330(a)(2) require the lien and levy notices to be given in person, left at your home or business, or "sent by certified or registered mail, return receipt requested." Section 6331(d)(2) says the same for the 30-day levy warning. A certified letter from the IRS is almost always one of those three: a deficiency notice, a lien notice or a levy notice, and each has a deadline printed on it.

Declining to sign for the letter does not stop the clock. The statutes count from the date the notice is mailed to your last known address, not from the date you receive it. A notice you never pick up still runs out.

What is the IRS final notice of intent to levy, and why is CP504 not it?

CP504 is the notice most people misread, in both directions. It is headed "Notice of Intent to Levy," it calls itself a final reminder, and it arrives certified. It satisfies section 6331(d), so 30 days after it the IRS may levy your state income-tax refund and may file a lien. What it does not do is give you Collection Due Process rights under section 6330. There is no Form 12153 for a CP504; the appeal route is the Collection Appeals Program, which is faster, narrower and not reviewable in court.

The mistake in the other direction is to relax after CP504 because the "final" notice has come and nothing happened. The LT11 or Letter 1058 that follows is the real last stop. It is the section 6330 notice, it carries the hearing right, and after its 30 days the IRS can take wages and bank balances. If you did nothing with the CP504, treat the next certified letter as urgent.

What happens in the 30-day Collection Due Process window?

A timely request on Form 12153, mailed to the hearing address on the notice (not the payment address), does four things, all spelled out on the form itself:

  • It prohibits levy in most cases until the IRS Independent Office of Appeals issues a determination.
  • It suspends the ten-year collection statute, and the suspended time is added to the end.
  • It gets you a hearing with Appeals, where you can dispute the amount you owe (if you had no earlier chance to), propose a collection alternative such as an installment agreement, an offer in compromise or currently-not-collectible status, claim innocent spouse relief, or ask for the lien to be withdrawn, subordinated or discharged.
  • It preserves the right to petition the Tax Court within 30 days of the determination (section 6330(d)(1)).

Attach a financial statement, Form 433-A for individuals or Form 433-B for a business, if you are proposing an alternative. The form does not require it, but Appeals cannot evaluate an offer or a hardship claim without one. If the balance is $50,000 or less and you simply need time, the form notes that you can set up an installment agreement online without a financial statement and without a hearing.

If you miss the 30 days, check the equivalent-hearing box. You can request one within one year of a levy notice, or one year plus five business days of a lien filing. It is the same hearing with the same issues, but it does not stop a levy, does not pause the collection statute and cannot be taken to court. Keep a copy of the form and proof of the mailing date either way; the postmark is your evidence that the request was timely.

What should you do in the first week?

  1. Read the notice number and the date. Count the deadline from the date on the letter: 30 days for a levy or lien notice, 90 for a deficiency notice.
  2. Pull your transcripts. Confirm the balance, the years involved and whether every return is filed. The IRS will not grant a payment plan or an offer with a missing return, so unfiled returns are the first repair.
  3. Decide what you are disputing. A deficiency notice is about whether you owe the tax; an LT11 is about how it will be collected. If the CP3219A came from a mismatch with a W-2 or 1099, our IRS audit representation page explains how to answer it. The 90-day petition deadline runs either way.
  4. File Form 12153 before you do anything else on an LT11, Letter 1058, CP90 or Letter 3172. Mail it certified, keep the receipt, check the equivalent-hearing box as a fallback, and state a reason: hardship, a payment plan, an offer, or a dispute about liability.
  5. Prepare the alternative in the same week. Appeals will ask what you want instead of a levy. Arrive with a Form 433-A and a specific proposal.
  6. Sign a Form 2848 if you want someone else to handle the calls. Once a power of attorney is on file, the IRS communicates with your representative.

Does Illinois send the same notices?

Not the same letters, but the same structure. The Illinois Department of Revenue issues a notice of deficiency or notice of tax liability and gives 60 days to protest, either through an administrative hearing or a petition to the Illinois Independent Tax Tribunal. Penalty and interest relief for reasonable cause goes to the Board of Appeals on Form BOA-1. IDOR can levy and can revoke a business's certificate of registration. Nothing you file with the IRS protects you from an Illinois collection action, and nothing filed with IDOR pauses the IRS. The state process is on our Illinois Department of Revenue page.

Why bring in a tax attorney who is also a CPA at the notice stage?

A Collection Due Process hearing is a legal proceeding with a financial statement at its center. The lawyer prepares the Form 433-A, the CPA reads it, and when they are the same person the proposal Appeals sees is consistent with the returns the IRS already has. Hani H. Khatib, Attorney at Law · CPA · LL.M. (Taxation), files the Form 2848 so that the IRS deals with him, files the hearing request and builds the alternative. If the determination has to be reviewed in court, representation can continue there. What you tell him about why the balance exists is privileged. The tax attorney page explains what happens when you call, and our articles on currently not collectible status and the IRS Fresh Start program describe the alternatives you can propose.
