IRS CP504B: what this intent-to-levy notice really means
A CP504B is the IRS telling your business, in writing, that it intends to levy — seize property or rights to property — for a balance it has already billed and you have not paid or arranged to pay. The IRS page says to pay or contact them no later than 30 days from the date of the notice. It is a serious step on the collection ladder, but in most situations it is not the last one: before levying most property, the IRS must still send a separate notice that carries your right to a Collection Due Process hearing.
CP504B in brief
- CP504B is the business-entity version of the CP504 notice of intent to levy, issued under IRC section 6331(d) after earlier bills went unpaid.
- The IRS states the window as: pay or contact them no later than 30 days from the date of the notice. The letter controls; no transcript or website changes that date.
- CP504B does not itself give you Collection Due Process (CDP) rights. For most property, a later Final Notice (LT11 or Letter 1058) carries the hearing right and its own 30-day window.
- After the 30 days the IRS says it may file a Notice of Federal Tax Lien, and in two employment-tax and federal-contractor situations it may levy without a further pre-levy hearing.
- Your options are pay in full, an installment agreement, an offer in compromise, a temporary collection delay, a dispute of the amount, or a Collection Appeals Program request — each with different requirements.
CP504B (notice of intent to levy, business taxpayers) at a glance
- What it is
- A notice of intent to levy sent to a business taxpayer under IRC section 6331(d): the IRS intends to seize property or rights to property for an unpaid balance, and may file a Notice of Federal Tax Lien.
- Why it was sent
- A balance (tax, penalty and/or interest) for a specific form and period was assessed and billed at least twice, and no full payment or approved arrangement has posted to the account.
- Who receives it
- Business taxpayers under an EIN — corporations, S corporations, partnerships and employers — for any business tax module with an unpaid balance. Individuals receive the parallel CP504.
- Tax type involved
- Any federal business tax the IRS has assessed and billed. Examples include Form 941 employment tax (including deposit penalties), Form 940 FUTA, and income-tax or penalty balances on business returns such as Form 1120-S.
- Deadline
- The IRS states: "pay your balance or contact us as soon as possible but no later than 30 days from the date of the notice." Count from the notice date printed on the letter. The letter controls.
- If it is ignored
- After 30 days the IRS may file a Notice of Federal Tax Lien and may serve a Disqualified Employment Tax Levy or Federal Contractor Levy. For most other property it must first send a Final Notice (LT11 or Letter 1058) with Collection Due Process hearing rights and its own 30-day window; if that passes unanswered, it can levy bank accounts, receivables and other property.
What a CP504B is, and where it sits on the collection ladder
The IRS collects an unpaid business balance in stages with different legal effects. A CP504B is the written notice of intent to levy that IRC section 6331(d) requires at least 30 days before a levy. A levy is the actual taking of property — a bank balance, receivables, equipment. A lien is the government's legal claim against your property; it arises by law once a bill goes unpaid and becomes public when the IRS files a Notice of Federal Tax Lien. CP504 goes to individuals; CP504B is the same notice sent to businesses under an EIN. Here is the sequence from Publication 594 and Publication 1660.
| Step | What the IRS sends | Legal effect | Your rights here |
|---|---|---|---|
| 1 | First bill (for a business usually a CP161), then at least one more bill | Notice and demand; interest and penalties accrue. | Pay, dispute, or set up a payment plan. |
| 2 | CP504B — notice of intent to levy | Satisfies 6331(d). After 30 days: possible lien filing, plus two levies that need no pre-levy hearing. | Pay, arrange, dispute, or request Collection Appeals Program (CAP) review. No CDP hearing right attaches here. |
| 3 | Final Notice — LT11 or Letter 1058 | The IRC 6330 notice; the IRS usually levies only after this was sent 30 or more days earlier. | Request a CDP hearing on Form 12153 within 30 days; a timely request generally pauses levy and preserves Tax Court review. |
| 4 | Levy; if a lien is filed, a lien-filing notice within 5 business days | Property is taken, or the lien becomes public. | CAP; a separate CDP right for the lien filing; an equivalent hearing within one year if the CDP deadline was missed. |
Why your business received it
A balance was assessed, billed, billed again, and no full payment or approved arrangement posted. Possible origins include a Form 941 quarter where deposits fell short of the liability reported, an unresolved penalty, a missing return the IRS assessed on its own figures, or a payment applied to the wrong period or EIN. Before you pay, confirm the balance is real: pull the business account transcript for that period and match every deposit and payment against what the IRS credited. A misapplied payment is one reason the balance can be wrong; the IRS page says to have "cancelled checks, amended return, etc." ready when you call.
How serious it is: what the IRS can do now, and what needs another notice
The IRS's own CP504B page says that if the amount is not received within 30 days it "may serve a Disqualified Employment Tax Levy or a Federal Contractor Levy," and that "in most other situations" it will first send a notice giving you the opportunity to request a Collection Due Process hearing. It may also file a Notice of Federal Tax Lien. A lien filing may therefore follow this notice; for most bank or receivables levies, the IRS first sends another notice with its own hearing window.
Two items on the notice get read more broadly than the IRS writes them. State refunds: the CP504B page says the State Income Tax Levy Program "currently" applies only to individual state refunds and "may include business state tax refunds in the future" — some sites say the company's refund is taken at this stage; the IRS page does not say that. Passports: the IRS certification rules define a "seriously delinquent tax debt" as an individual's enforceable debt above a yearly-adjusted threshold ($66,000 for 2026), reaching business taxes only where the person is "personally liable." A corporation's Form 941 balance does not certify the owner's passport; a Trust Fund Recovery Penalty assessed against the owner personally could.
The deadline, as the IRS states it
What to gather before you call or pay
- The notice: date, form and period, balance split into tax, penalty and interest, and the phone number on it.
- Every earlier notice for the same period — the first bill (CP161) or a penalty notice such as CP162.
- The business account transcript for that period, plus your payment evidence: EFTPS confirmations, cancelled checks, bank statements.
- Proof that all required returns are filed, plus current deposit records. Collection alternatives have different compliance conditions; an offer requires current-quarter and two preceding quarters of required federal tax deposits.
- Who speaks for the business: an officer, or a representative with a Form 2848. A Form 8821 lets someone see the account, not negotiate.
Your response menu and what each option requires
| Option | What it does | What the IRS requires or warns |
|---|---|---|
| Pay in full | Stops further failure-to-pay penalty and interest once posted. | Pay to the exact form and period on the notice. If the amount is wrong, call the number on the notice with your paperwork instead. |
| Installment agreement | Monthly payments; collection generally pauses while a request is pending and the plan is kept. | All required returns filed. Applicable penalties and interest continue, and a Notice of Federal Tax Lien may still be filed. The payment-plan page now offers Simple Payment Plans to qualifying businesses; use the current eligibility flow or call the number on the notice. The reduced late-payment penalty that Publication 594 describes is limited to qualifying individuals, not business entities. |
| Offer in compromise | Settles for less than the full balance on doubt as to liability, doubt as to collectibility, or hardship. | All returns filed and federal tax deposits current "for the current quarter and the two preceding quarters." A business entity cannot use the low-income certification available to qualifying individuals; follow the current Form 656 instructions for the application fee and initial-payment rules. |
| Temporary collection delay (currently not collectible) | Collection paused after the IRS determines the business has no current ability to pay. | Financial information and supporting records are required. Penalties and interest continue; a lien may still be filed. |
| Collection Appeals Program (CAP) | Fast Appeals review of a lien filing, a levy, or a rejected or terminated installment agreement. | Form 9423 after a Collection manager conference. CAP cannot challenge the liability itself; the decision is binding with no court review. |
What happens next, procedurally
If the balance is not paid or arranged
- Day 0 to 30: the CP504B window.Pay, arrange, dispute, or request CAP. A pending installment request or offer generally holds collection while it is considered.
- After day 30: a lien may be filed; limited levies are possible.A filed Notice of Federal Tax Lien must be followed by a lien-filing notice within 5 business days, with its own 30-day CDP right. Disqualified Employment Tax Levies and Federal Contractor Levies may be served without a further pre-levy hearing.
- Final Notice, then levy.For most other levies the IRS sends the 6330 notice (LT11 or Letter 1058); you have 30 days from its date to request a CDP hearing on Form 12153. The IRS's levy page says it will "usually levy only after" that notice was sent at least 30 days earlier. Unpaid Form 941 withholding can also bring a Trust Fund Recovery Penalty proposed against the responsible people personally.
The process weakness behind a CP504B
A CP504B means an assessed balance remained unresolved through earlier billing. That can happen because a known balance was not paid or arranged, or because a deposit shortfall, penalty, misapplied payment, or address problem was not resolved. The notice is the collection event; the underlying process question is why the balance remained open.
| Layer | What it is | For a CP504B |
|---|---|---|
| Legal requirement | Statute or regulation, with a defined consequence. | Pay assessed tax on notice and demand. Deposit withheld employment taxes on your deposit schedule. Report an address or responsible-party change on Form 8822-B. |
| IRS administrative expectation | What the IRS expects you to do or show when it acts. | Respond inside the 30-day window with payment proof ready. Be current on returns and deposits before asking for a plan or offer. |
| Defensibility control | Prudent practice — not law, but what keeps a small balance from becoming a levy notice. | Reconcile each quarter's 941 deposits against the IRS transcript, not only your payroll software. Name one person to open and log every IRS letter. Read the account between filings so a posted balance is investigated on a recurring schedule. |
The third layer is where CompDefend works. Measuring your business tax defensibility starts with whether these controls exist, and monitoring the IRS business account is how that control runs without anyone remembering to pull a transcript. For the modules it supports, CompDefend Radar reads the account weekly and flags a new balance due, an added penalty, a trust-fund indicator, or collection context such as a lien filing or currently-not-collectible status. It cannot tell you a CP504B was mailed — a transcript code never names a specific letter — and it never computes a deadline.
When to bring in a CPA, enrolled agent or attorney
Handle it yourself when the balance is correct and you can pay it or fit it into an installment agreement. Bring in a CPA, enrolled agent or tax attorney with a Form 2848 when the balance includes unpaid Form 941 withholding (which can become a personal trust fund liability); when the amount is wrong and needs abatement or a payment trace; when you are weighing an offer in compromise or hardship status; when a revenue officer is assigned; or when you requested an employment-tax CDP hearing in the past two years. The Taxpayer Advocate Service is independent and free when the IRS process itself is failing you; it cannot extend hearing deadlines.
What to gather now
- The notice: date, form, period, balance by tax/penalty/interest, and the phone number on it
- All earlier notices for the same period and any prior responses
- The business account transcript for that form and period
- Proof of every payment and deposit: EFTPS confirmations, cancelled checks, bank statements
- Confirmation that all required returns are filed and current-quarter deposits are on schedule
- Form 2848 for any representative who will negotiate; Form 433-B information if you will ask for a plan or delay
What to do now
- Verify the balance against the transcript before paying, including whether any payment was applied to the wrong form, period or EIN
- Inside the 30-day window: pay in full, call the number on the notice to set up an installment agreement or dispute the amount, or submit an offer or hardship request
- Document every IRS contact by date, time and employee ID
- If a specific collection action is wrong, ask for a Collection manager conference and, if needed, file Form 9423 (CAP)
- Bring required payroll deposits current for the collection alternative you request; an offer requires the current quarter and two preceding quarters
- Update the business address with Form 8822-B if earlier notices went astray
Bring in a CPA, enrolled agent or tax attorney with a Form 2848 when the balance includes unpaid Form 941 withholding (personal trust fund exposure), when the amount is wrong and needs abatement or a payment trace, when you are considering an offer in compromise or hardship status, when a revenue officer is assigned, or when you requested an employment-tax CDP hearing in the past two years.
Where CompDefend fits — and where it does not
What CompDefend does
- Monitors supported federal business-account modules weekly under a Form 8821 tax information authorization, giving the business a recurring way to detect a new balance due, an added penalty, a trust-fund indicator, or collection context (lien filing, currently-not-collectible, account suspended).
- Measures, free, whether the controls that keep balances from aging unnoticed — deposit reconciliation, filing discipline, account visibility — exist in your business, and returns a Federal Tax Defensibility Index with the weak domains named.
- Explains what the IRS account shows in plain language, so the call you make inside the 30-day window starts from the facts.
- Builds documented reasonable compensation studies when an S corporation's owner pay is the weak point behind a payroll balance.
What CompDefend does not do
- Tell you that a CP504B was mailed or compute any deadline. Radar reads transaction activity, and a transaction code never names a specific letter — the notice you hold controls the date.
- Represent your business before the IRS, request a hearing, negotiate a payment plan or offer, or file returns. Form 8821 permits reading account information only; it is not a Form 2848 power of attorney.
- Form 1040, Form 1065, Form 1120, and individual civil-penalty accounts are outside Radar's scope. Its supported modules are 1120-S, 941 and 940 under one business EIN.
- Stop a levy, remove a lien, or promise any IRS outcome. Those depend on your response and the IRS's decisions.

Once this notice is handled, the useful question is why the balance remained unresolved. The free assessment scores the related deposit, filing and account-visibility controls and names what to strengthen.
