CP504B: what the 30 days on your notice actually means

A CP504B is the business version of the intent-to-levy notice, and unlike the individual one it prints a number of days. Here's what that number is measuring.

A CP504B is the business version of the intent-to-levy notice, and unlike the individual one it prints a number of days. Here's what that number is measuring.

Your notice says 30 days and you are trying to work out what happens on day 31. Reasonable. The answer is that day 31 is not a cliff, and the 30 days on this letter is not the 30 days that people mean when they talk about appealing an IRS levy. Those are two different periods on two different letters, and knowing which one you're holding changes what you should do this week.

(800) 236-3741, or (502) 658-6328 locally — answered 24 hours a day, seven days a week. After hours you reach our AI receptionist, not voicemail — it answers the common questions, takes your details, and books you the first available thirty minutes. During office hours you reach the office directly, in Georgetown.

The first call is free. Thirty minutes. No obligation, no conditions, no strings. Book a time →, or call the numbers above.

Thirty minutes tells you how much of the balance is payroll tax and how much is not — which is the only question on this page whose answer changes what you do this week — and what personal exposure sits behind it.

Every case here is reviewed and worked by Katherine personally. Not a processing department, and not a case manager relaying messages from someone you never meet.

Key takeaways

•A CP504B is a Notice of Intent to Levy sent on a business account. The IRS's own instruction is to pay or make contact "no later than 30 days from the date of the notice."
•That 30 days is the period the IRS has to wait before it can levy. It is not a deadline to appeal, and Form 12153 is not the response to it.
•In most situations the IRS still has to send a separate Final Notice carrying your hearing rights — the CP297 — before it levies business property.
•One exception can shorten that, and it is narrower than it sounds. A disqualified employment tax levy reaches only a business that has already requested a Collection Due Process hearing on employment taxes in the last two years. For most businesses that has never happened — but whether it did, and when, is on the account rather than on the notice.
•There is an appeal available at this stage: a Collection Appeals Program request, on Form 9423, within the same 30 days.
•Contact inside the 30 days is genuinely useful, because it is the point at which a payment plan is easiest to put in place.

What a CP504B is

A CP504B is the notice the IRS sends a business to say it intends to levy because a balance has gone unpaid. The IRS titles it Notice of Intent to Levy and lists what it may reach: wages and real estate commissions, accounts receivable, bank accounts, business and personal assets, Social Security benefits, and state tax refunds.

That list is what the notice is warning you about eventually. It is not a description of what happens next week.

Your clock — and which one it is

The IRS's CP504B page states a deadline: "You should pay your balance or contact us as soon as possible but no later than 30 days from the date of the notice." Two things about that sentence are worth slowing down for.

First, what it is measuring. Section 6331(d) of the tax code says the IRS may not levy until it has notified you in writing of its intention to do so, and that notice has to go out "no less than 30 days before the day of the levy." The 30 days on your CP504B is that period. It is a constraint on the IRS's timing, expressed to you as an instruction.

Second, what it is not. It is not the 30-day window to request a Collection Due Process hearing. That window belongs to a different letter — the CP297, the Final Notice of Intent to Levy and Notice of Your Right to a Hearing — and it is requested on Form 12153.

And here is the part of the IRS's sentence that most pages leave off, and it is the part a business needs. The web page reads: "If we don't receive the amount due within 30 days from the date on the notice, we may serve a Disqualified Employment Tax Levy or a Federal Contractor Levy. In most other situations, before we levy on your property or rights to property, we'll send you a notice that gives you the opportunity to request a Collection Due Process hearing." The notice itself adds four more words that matter more than all the rest: "unless we have already issued one to you."

That tail is the second exception, and it is the commoner of the two. Section 6330(a)(1) requires the hearing-rights notice "only once for the taxable period." If a CP297 already went out on this quarter and nothing was done, this letter is a reminder rather than a step, and the further letter this page describes may not be coming. Whether one was issued is on the account, not on the notice.

Read the order of those two sentences. In most situations another letter comes first. In one specific employment-tax case it may not — and that case is much narrower than the name suggests.

Section 6330(f)(3) excepts a disqualified employment tax levy from the pre-levy hearing requirement, and section 6330(h)(1) defines it: a levy for employment taxes where the taxpayer "(or any predecessor thereof) requested a hearing under this section with respect to unpaid employment taxes arising in the most recent 2-year period before the beginning of the taxable period with respect to which the levy is served."

The trigger is a prior Collection Due Process hearing request on payroll tax within two years — not the mere presence of payroll tax in the balance. For most businesses reading this, that has never happened, the exception does not apply, and the Final Notice protection is intact. If it has happened, the date of that earlier request is the fact that decides it, and it is on the account.

Either way the right does not disappear: the same subsection entitles you to a hearing within a reasonable period of time after the levy.

A business that files Form 12153 in response to a CP504B has used the right form at the wrong stage.

But there is a form for this stage, and your notice names it. Under the heading Right to request an appeal: "If you don't agree with our intent to levy or file a Notice of Federal Tax Lien, you have the right to request an appeal under the Collection Appeals Program (CAP) before the collection action takes place." Requested by calling the number on the notice or sending Form 9423, within 30 days from the date of the notice. The notice itself adds the distinction: "The CAP is different from the Collection Due Process (CDP) Program."

CAP is quicker and can look at a wider range of collection decisions. What it does not carry is a route to Tax Court or a pause on the ten-year collection period — the CDP hearing on the next letter carries both. So CAP is the tool for disagreeing with how the account is being handled now; it is not a substitute for the hearing right that has not attached yet.

One exception people import from the individual notice does not currently apply to you. Section 6330(f)(2) lets the IRS levy a state tax refund without the pre-levy hearing notice — but the program that does it reaches individual refunds only. The IRS says so on this notice's own page: "Currently, levying your state tax refund through the State Income Tax Levy Program (SITLP) only applies to individual state tax refunds but may include business state tax refunds in the future." Note the word currently; the IRS's own sentence anticipates the change.

For a business, the exception that matters is the employment-tax one above.

The letter	What its 30 days is	What you can file
CP504B	The IRS's waiting period before it may levy	Form 9423 — a Collection Appeals Program request, within the same 30 days
CP297	Your window to request a hearing, from the date on the notice	Form 12153 — Collection Due Process, and this one reaches Tax Court

Not sure which kind of balance you have? That is the one thing worth a call before you do anything else on this list — (800) 236-3741 or Book thirty minutes →.

What to do while the 30 days is running

Read the steps below in order — the first one decides the rest.

Check whether the balance is a filing problem or a payment problem.

Businesses commonly get here through an unfiled 941 or a deposit that posted to the wrong quarter, not through a decision not to pay. Which one it is determines everything downstream, and it is on the account transcript.

How to pull IRS transcripts without calling →

Work out whether payroll tax is involved.

If any part of this balance is trust fund tax — the money withheld from employees' pay — it is a materially different problem, because that portion can be assessed against individuals personally. That does not happen on the strength of a CP504B, but it is the direction the file travels if nothing changes.

How personal liability for payroll tax actually works →

Make contact inside the 30 days.

Not because day 31 triggers anything, but because a business payment plan is easiest to arrange while the account is still in this stage, and it becomes an argument rather than an application after the Final Notice.

Protect receivables deliberately, not hopefully.

An accounts receivable levy reaches your customers, and it is the one that does commercial damage out of proportion to the money involved.

Working out which kind of balance you have takes one look at the account. It is the only question on this page whose answer changes what you do this week. (800) 236-3741, or Book thirty minutes →.

What happens if you do nothing

The sequence continues, and the next letter is the one that matters.

A CP504B is not the end of the line — a Final Notice of Intent to Levy still has to be issued before the IRS can levy the business bank account or receivables, and that letter carries a 30-day hearing right this one does not. So the honest answer is that nothing happens on day 31 of this notice.

Three things do keep moving, though, and they are the reason "wait and see" is not free. Interest and penalties continue to accrue on the balance throughout. The account moves closer to assignment — and in practice that is the difference between choosing which option you use and being assigned one. And if any part of the balance is payroll tax, the trust fund question is running on its own track behind this letter, aimed at individuals rather than at the entity.

The Kentucky note

A Kentucky business with a federal balance usually has a state one too, and the state process is not a slower copy of the federal one.

Kentucky's Department of Revenue can levy administratively, without a court judgment, and its statutory notice floor before doing so is ten days — a written notice of intention to levy, sent by certified mail to your last known address, no less than ten days before the levy date under KRS 131.510(1). The federal floor on the same step is 30 days. Kentucky also has enforcement routes the IRS does not, including action against professional and occupational licenses and against vehicle registration under KRS 131.1817.

The practical consequence for a business holding both: the state balance can move faster than the federal one, and a federal payment plan does nothing about it. How a Kentucky balance and an IRS balance interact →

What we see

When a business owner brings us a CP504B, the letter is rarely the interesting document — the account behind it is. The first thing we do is split the balance into trust fund and everything else, quarter by quarter, because the owner is usually reading one number where the IRS is reading two different problems, and only one of them follows a person home. The thing we ask people to stop doing straight away is funding the old balance out of the current deposits; it is an understandable instinct and it turns one late quarter into a pattern. What owners are most often surprised by is that closing the company does nothing to the payroll piece.

Katherine — you are welcome to rewrite this for what a CP504B really has underneath it when it reaches your desk.

The three business situations that change this

Asking for a payment plan or an offer stops the levy while it is being processed. For a business this is the cheapest protection available at this stage: section 6331(k) bars levy while a request for an installment agreement or an offer in compromise is pending, for 30 days after a rejection, during an appeal of that rejection, and while an agreement is in effect. For a business with receivables exposure this is the most valuable fact on the page: the application itself is protective, from the date the IRS accepts it for processing rather than the date you send it.

It bars levy, not everything. A Notice of Federal Tax Lien can still be filed, interest and penalties still accrue, and a levy already served is a release question rather than a section 6331(k) question.

Two limits travel with it, and for a business the jeopardy exception is the one worth knowing about. Section 6331(k)(3) borrows the exceptions in section 6331(i)(3), so the bar gives way where the IRS finds collection is in jeopardy, and it does not stop a federal refund being taken as an offset under section 6402. And a pending request suspends the ten-year collection period — the price of the protection, and it belongs in the decision.

If trust fund tax is in the balance, there is a second exposure and it is personal. The portion withheld from employees' wages can be assessed against individuals the IRS determines were responsible for paying it over and willfully failed to do so. It has its own letter and its own protest window, and — the part owners are most surprised by — it survives the entity. Closing the business does not close it. How personal liability for payroll tax actually works →

If the business has already stopped trading, the levy exposure follows the assets, and an entity with nothing left is not where the effort belongs. The live question in that situation is the personal one above, and it is a different problem than this letter.

One more, on what can actually be reached — and read this one carefully, because it turns on a single word. Section 6334 exempts books and tools of a trade up to an annually adjusted amount. There is also a procedural protection for property used in a trade or business: the IRS cannot levy it without a written determination that your other assets are insufficient, or a jeopardy finding.

But section 6334(a)(13)(B)(ii) applies that protection to property used in the trade or business of an individual taxpayer. If you trade as a sole proprietor, it is yours. If the equipment is owned by a corporation or an LLC, it is not — and the equipment has no protection beyond the ordinary rules. That is a distinction most pages skip, and it points the wrong way for most incorporated businesses, which is presumably why.

Our incentive here points the other way, and you should know that

We would get more calls by telling you this letter is an emergency, and for most businesses it is not one. If the balance is income tax and there is no employment tax in it, a CP504B is a real step in a sequence with another letter still to come, and a phone call to the IRS is a sensible response to it. We would rather tell you that than take the call.

Here is where that stops being true. Any one of these puts you on the shorter path:

Any part of the balance is payroll tax. The trust fund portion runs on its own track, aimed at individuals rather than at the entity.
A Collection Due Process hearing was already requested on employment taxes in the last two years. That is the one situation in which a levy can arrive with no further letter.
A CP297 already went out on this quarter. The hearing-rights notice is required only once per period, so this letter may be a reminder rather than a step.
Receivables are your real exposure. A levy served on your customers does commercial damage out of all proportion to the money collected.

Working out which of those is you takes one look at the account, and that is the call. (800) 236-3741, or Book a time →.

Frequently asked

Is a CP504B different from a CP504?

They are the same step in the sequence, sent to different kinds of taxpayer. The one practical difference worth knowing is that the IRS's published guidance for the business notice states a 30-day period and the guidance for the individual one does not.

Can the IRS levy my business bank account 30 days after this letter?

In most situations, not on this letter alone — a levy on property of that kind requires the Final Notice first, which for a business is a CP297. Two things can change that. A disqualified employment tax levy may be served without a Final Notice, but only where you already requested a Collection Due Process hearing on employment taxes in the last two years. And if a Final Notice was already issued for this tax year at some earlier point, the law requires it only once for that period — see below.

Should I file Form 12153 now?

No. Form 12153 requests a Collection Due Process hearing, and the right it exercises attaches to the Final Notice, not to this one. Filing it now does not preserve anything and does not start a clock. Form 9423 is the one that belongs to this stage, if you disagree with the intent to levy.

Is my business state tax refund at risk?

Not through the program that takes individual state refunds — the IRS says that one currently applies to individual refunds only. The nearer exposure for a business is a levy on the bank account or on receivables, and, where employment tax is involved, one that can arrive without a further letter.
