Got an IRS letter? What to do in the first 72 hours

It was 6:17 on a Tuesday morning when Michael found out the money was gone.

Not all of it. Just enough to make the rest of the day impossible.

His business checking account had held $14,286 the night before. By morning the bank had frozen $12,400 of it. The notice on his online banking screen said the hold was in connection with a levy from the Internal Revenue Service and gave him a phone number for the bank's legal department. Nobody answered.

Payroll was due Friday. The truck payment was already late. A lumber supplier had told him on Monday that one more late invoice and deliveries would stop. And now, somewhere inside a federal agency he had never set foot in, somebody had pushed a button that could take down a construction company he had spent nineteen years building.

Michael had known about the tax problem. He just had not known it could become this problem.

For almost two years he had been putting IRS letters in a kitchen drawer. The first one asked for money. The next one added penalties and interest. Then they got shorter and the type got bolder. He had promised himself he would deal with it when business picked up. Business never quite picked up enough.

Now his wife was asking if they were going to lose the house. His crew was expecting to be paid. And Michael was staring at a bank balance he could see but could not use, with three questions in his head.

How did this happen?

Can I stop it?

Is there anything left to save?

The answers depend on facts Michael does not yet know, rights he never learned he had, and a handful of decisions he is about to make very quickly. Some of them will be wrong.

His first mistake was not owing the IRS money. Plenty of people owe the IRS money. His first mistake was believing that not knowing was safer than knowing.

This book starts where Michael's understanding should have started: with the difference between a tax debt and a financial catastrophe. They are not the same thing. The distance between them is measured in letters, and the letters are not random.

Owing money and facing enforcement are two different things

Here is the single most useful idea in this book. It comes before anything else for a reason.

The IRS saying you owe money is one event. The IRS taking money is a different event. Collection is subject to notice requirements, hearing rights and statutory exceptions. Those protections matter, but they do not make every reminder in a notice ladder legally mandatory or guarantee another warning before action.

Receiving a bill does not mean a levy will happen tomorrow. It also does not establish a safe waiting period. The tax period, assessment, earlier notices, current collection status and applicable exceptions determine what can happen next. Check those facts promptly rather than guessing from the latest envelope.

The flip side is also true. Feeling no urgency because nothing has happened can be dangerous. Charges may continue while the IRS retains collection options. A new reminder does not necessarily restart an earlier hearing deadline, and different tax periods can have different procedural histories.

So the first skill is reading the signposts.

Recognizing the letters—not a guaranteed sequence

For an individual who filed a return and did not pay the balance, these are common collection notices. They can appear in this general progression, but it is not a required sequence. The notice number helps identify the document; it does not establish your enforcement risk by itself.

CP14. Usually the first bill for an unpaid return balance, including applicable penalties and interest. Verify the amount and follow the payment or contact date printed on the notice. Do not assume an approximate three-week payment period is a hearing deadline or that another reminder is guaranteed.

CP501. A reminder that the balance remains unpaid. Check payments, the tax period and the response instructions. The code alone does not prove that collection is barred or that a previously expired hearing deadline has restarted.

CP503. An unpaid-balance reminder that requires attention. A lien is a claim against property, not a seizure. Check the account and discuss payment or hardship options; the IRS does not have to send every reminder before moving forward.

CP504. An urgent notice of intent to levy under section 6331(d). The IRS may levy a state income tax refund after the required notice and may file a Notice of Federal Tax Lien. Before most other levies, it generally must provide the required CDP hearing opportunity, unless a statutory exception applies. If a final hearing notice already covered the tax and period, do not assume another must follow CP504. CP504 itself does not create a new universal 30-day CDP window or establish that wages and bank accounts are safe. Read the CP504 guide, check earlier notices and contact the notice office promptly.

LT11, Letter 1058, or CP90. These notices concern different collection situations, but each offers a levy Collection Due Process (CDP) hearing. For a levy CDP notice such as LT11, Letter 1058 or CP90, the request period is 30 days from the date of the notice. Follow the printed hearing deadline; do not count from when you opened the envelope. A prior CDP notice for the tax and period may already have provided the hearing opportunity. A timely levy CDP request generally prohibits levy for the covered taxes and periods during the CDP process. Statutory exceptions include jeopardy, state-refund, disqualified employment tax and federal contractor levies; these can carry post-levy hearing rights. The IRS normally does not levy during the lien-hearing request period and related CDP process, but a lien hearing is not an unconditional statutory bar to levy. A timely CDP request suspends the collection limitation period until the determination becomes final or you withdraw the request in writing.

Mark the hearing deadline printed on your actual notice and preserve proof that you submitted your request on time.

Letter 3172. For Letter 3172, the IRS must notify you within five business days after filing the Notice of Federal Tax Lien. The 30-day lien CDP request period begins after that five-business-day period. Use the hearing deadline printed on Letter 3172, not its letter date plus 30 days. The lien is already filed; requesting a hearing does not itself remove it. It can arrive before, after, or alongside a levy notice.

If you miss the CDP deadline, an equivalent-hearing request must be postmarked on or before the end of one year from the date of the levy CDP notice, or one year plus five business days from the lien filing date for a lien notice—not one year from Letter 3172’s date. An equivalent hearing does not legally prohibit levy, suspend the collection limitation period, or provide the same right to Tax Court review.

Use current Form 12153, identify the notice, taxes and periods, explain why you disagree or propose a collection alternative, and sign the request. Include a copy of the notice. Send it to the hearing-request address on the notice, not the payment address. If you want to fax it, call the number on the notice to confirm the correct fax destination and instructions. Keep a copy and proof of timely submission. Calling the IRS or discussing a payment plan does not replace a timely hearing request. For an equivalent hearing, check the Equivalent Hearing box in item 2 of the current form.

There are other letters. If a revenue officer, meaning a human collector rather than the automated system, has been assigned to your case, you may get Letter 725-B asking you to call and schedule a meeting. If you did not file at all, you will get a different series asking for the return before any of this starts. We will get to those. But the sequence above is the spine of federal tax collection for most people, and if you can place your own letter on it, you already know more than Michael did on that Tuesday morning.

Where Michael was on the path

Let me go back to the kitchen drawer, because it is worth seeing what was in it.

There were two years of letters. Three tax years of debt, because Michael had filed each return on time and then not paid, which is a very common pattern for self-employed people. The oldest year had gone through the full sequence: CP14, CP501, CP503, CP504, and then an LT11 dated fourteen months ago. The thirty-day hearing window on that LT11 had closed thirteen months ago. The two newer years were behind it on the path, one at CP504 and one at CP503.

So for the oldest year, the IRS had done everything the law required before it could levy. It had waited over a year beyond the minimum. Then it had sent a levy to his bank.

The levy Michael was looking at was not a surprise attack. It was the end of a path he had been walking with his eyes closed. Every signpost had been in the drawer.

I am not telling you this to pile on Michael. I am telling you because the drawer is where most people keep their tax problem, and the drawer is where the information you need already is. If you have a drawer, go empty it onto the table. Sort the letters by tax year and then by date. Find the notice numbers. You are about to learn where you stand, and I promise you it is more specific and more workable than the thing you have been imagining.

What the notice actually tells you

Pick up any one of the letters. Find these things on it, in this order.

The notice number, usually in the upper right corner. Use it to find the appropriate notice instructions, not as a substitute for the account history.

The tax year or tax period it covers. Sort the papers by each tax and period. The IRS may have provided hearing rights for one period but not another; the latest notice code cannot tell you that on its own. Check earlier hearing notices, applicable exceptions and current account information before deciding which liabilities a proposed levy can cover.

The date. Deadlines run from this date, not from when it reached you.

The amount, broken into tax, penalty, and interest. Look at how much of the total is not tax. On an older debt, penalties and interest can be a third or more of what you owe. That portion is not fixed. Some of it may be reducible, and we will cover how in Chapter 12. The underlying tax is the hard part. Everything stacked on top of it is softer than it looks.

The response deadline and what the IRS says will happen if you miss it. A lien filing and a levy are different actions. CP504 warns of collection, including a state-refund levy, without promising another warning or a new CDP period. A notice offering hearing rights has its own instructions and deadline; a phone call or payment discussion does not replace the required hearing request.

The phone number and the address. Both are real. Both are yours to use.

A short detour on whether the letter is real

Before you act on any letter, make sure the IRS sent it. Fake IRS notices exist, and the people who send them time their mailings for tax season and for the weeks after real notices go out. The real IRS starts with the mail. It does not open a case by phone, text, email, or social media. It does not threaten arrest for a civil debt. It does not demand payment by gift card, wire, or cryptocurrency. It does not refuse to let you ask questions.

If a letter has a notice number, you can look that number up on IRS.gov and see a description of what the real version says. If you have created an online account with the IRS, which you should, the balances and notices there are authoritative. A real notice and your online account will agree. A fake one will not be reflected anywhere.

I mention this here, this early, because frightened people are the preferred targets of this kind of fraud, and the one piece of mail you most want to be fake is the one you should check first.

Why the IRS sends so many letters

People sometimes read the long sequence of notices as bureaucratic padding. It is the opposite, and the history is worth knowing because it tells you how seriously to take each letter.

Congress strengthened collection safeguards through the IRS Restructuring and Reform Act of 1998. Notice and hearing rights, independent review, limits on seizures and taxpayer assistance are meaningful protections. But the familiar sequence of reminder codes is not itself a statutory checklist: not every rung requires a separate pause, and some levies have post-levy rather than pre-levy hearing rights.

That means the letters deserve close attention, not automatic assumptions about delay. A timely levy CDP request generally prohibits levy for the covered taxes and periods, subject to exceptions. Lien hearings and equivalent hearings have different protections. Read the actual instructions and protect any available deadline rather than waiting for a supposedly final chance.

I will say something here that I will repeat in different forms through the book. The system is slow, and the slowness is your friend only if you use it. If you do nothing, the slowness simply means more interest accrues before the inevitable. If you use the time to understand your account, get current on filing, and choose an option, the same months become the space in which your problem gets solved.

What happens next for Michael

Michael called the bank again at 9:00 and reached a person. She told him two things he did not understand yet, and they are worth previewing because they are good news.

First, the bank was not sending the money to the IRS that day. A bank levy requires the bank to hold the funds for twenty-one days before remitting them. The hold is unpleasant, but the twenty-one days exist specifically so the taxpayer can contact the IRS and try to get the levy released or modified. Michael had three weeks he did not know he had.

Second, the levy reached only what was in the account at the moment it hit. Money deposited the next day was not covered. A bank levy is a snapshot, not a drain. If a customer paid him Wednesday, that money would be his.

Neither of these facts solved the problem. Payroll was still Friday. But they changed the shape of it, from "the IRS has emptied my business" to "the IRS has frozen one day's balance for three weeks, and I have three weeks to make my case."

That is a different problem. It has steps. We will walk through the steps in Chapter 15. First, though, Michael needs to understand what the agency on the other end of that levy can and cannot actually do to him, because he is about to make decisions based on what he imagines its power to be, and his imagination is wrong in both directions.

Can the IRS take his house? Can it take his truck? Can it put him in jail? Can it take every dollar he earns until the debt is gone?

The answers are no, probably not, no, and no. But each of those answers has a shape, and the shape is the subject of the next chapter.
