CP504 and LT11 are both serious IRS notices — but they're not the same. Here's exactly what each means, which is worse, and what to do right now. Call (888) 684-4992.
If you've received a CP504 or an LT11 — or if you're trying to understand the difference between the two — here's the short answer: both are serious, the LT11 is more urgent, and either one requires immediate action.
The longer answer matters, because the CP504 and LT11 carry different legal authorities, different rights, and very different consequences if you miss the response window. Understanding the distinction could be the difference between resolving your debt on favorable terms and watching your wages get garnished.

The CP504 is the fourth notice in the standard IRS collection sequence, following the CP14, CP501, and CP503. By the time it arrives, the IRS has exhausted its standard reminder cycle and is now escalating to enforcement.
The CP504 is issued under Internal Revenue Code Section 6331(d) and gives the IRS authority to levy your state income tax refund. That's it — at this stage, the IRS can intercept your state refund, but it cannot yet touch your wages, bank accounts, or other assets without issuing a Final Notice first.
The CP504 also serves a procedural function: it is the required legal predicate for the LT11. The IRS must issue a CP504 (or equivalent) before it can issue a Final Notice of Intent to Levy. Think of the CP504 as the last formal warning before the IRS shifts into full enforcement mode.
What you should do if you have a CP504: Act immediately. You are one step away from the LT11 — and once that final notice is issued and its 30-day window passes, the IRS can garnish your wages and freeze your bank accounts without any additional warnings.
The LT11 (also issued as LT1058 or Letter 1058, depending on which IRS unit sends it) is the Final Notice of Intent to Levy. It carries two critical elements the CP504 does not:
1. Full levy authority. Once the LT11's 30-day window closes, the IRS can garnish your wages, freeze and seize your bank accounts, intercept your Social Security benefits, and in serious cases, seize physical property — all without a court order.
2. Your Collection Due Process (CDP) hearing right. Federal law gives you the right to request a CDP hearing within 30 days of the LT11 date. This is one of the most powerful rights in the tax collection process — when you request a CDP hearing in writing, all IRS enforcement activity is automatically suspended while the hearing is pending.
Miss that 30-day window, and you lose the automatic suspension right. The IRS can begin levying immediately, and your appeal options narrow significantly.
This is the most important practical difference between the two notices.
The CP504 does not trigger CDP hearing rights. You cannot use a CP504 to automatically stop IRS enforcement. You can request a Collection Appeal Program (CAP) hearing, but CAP hearings do not carry the same automatic suspension of enforcement that CDP hearings do.
The LT11 does trigger CDP rights — but only if you request the hearing within 30 days.
This means:
- If you have a CP504: your best protection is resolving the balance or getting a resolution agreement in place before the LT11 is issued
- If you have an LT11: your best immediate protection is requesting the CDP hearing in writing right now, while simultaneously working toward a resolution agreement
If you ignore the CP504: The IRS issues an LT11 or LT1058. You then have 30 days to request a CDP hearing or face full levy authority.
If you ignore the LT11: The 30-day window closes. The IRS begins enforcement — typically wage garnishment or bank levy — without additional notice. At this point, stopping enforcement requires either an emergency levy release or an approved resolution agreement, and your wages or bank funds may be affected during the processing period.
The cost of inaction compounds at every step. The balance you owe today is the lowest it will ever be. The options available to you today are the most numerous they will ever be.
Yes — but the mechanism is different for each.
To stop the CP504 from escalating: Get a resolution in place. An approved installment agreement, a submitted Offer in Compromise, or a documented hardship application will all pause the IRS's escalation. The key is acting before the LT11 is issued.
To stop the LT11 from becoming a levy: Request a CDP hearing in writing within 30 days — this automatically suspends enforcement. Simultaneously work with a tax professional to negotiate the resolution that will serve as the basis for resolving the hearing.
To stop an active levy (after the LT11 window has closed): An approved installment agreement or OIC will result in the IRS issuing a levy release, but this takes time to process. Your wages or bank accounts may be affected during the processing period.
The CP504 tells you the IRS's automated collection process is nearly complete. A human being — a revenue officer or ACS agent — is likely to be assigned to your case soon if they haven't been already.
The LT11 tells you a specific IRS personnel action is now available: they can act on your account at any time. Your case has moved from "automated" to "active."
Acting at the CP504 stage means you're dealing with the end of an automated process — resolution is relatively straightforward if you move quickly. Acting at the LT11 stage means you're dealing with active case management — the resolution process is the same, but the clock is tighter and the stakes of missteps are higher.
Which is worse — a CP504 or an LT11?
The LT11 is more immediately dangerous because it carries full levy authority and the 30-day CDP hearing clock. However, both notices require urgent action. The CP504 is serious precisely because it is the last step before the LT11.
Can I get both notices at the same time?
Not typically. They are sequential — the CP504 must be issued before the LT11. However, if you've moved or not been checking your mail, you may receive both in close succession, or find an LT11 waiting when you finally open a pile of IRS correspondence. If this has happened, the LT11 date controls — check it immediately.
I got a CP504 weeks ago and just received an LT11. Have I lost my chance to stop enforcement?
Not yet — but you need to act today. Request the CDP hearing in writing immediately. Until that 30-day window from the LT11 date closes, you still have the automatic suspension right. Call us and we'll help you do this correctly.
Does the CP504 affect my passport?
If your balance exceeds $62,000, the IRS can certify your debt to the State Department as seriously delinquent, which can result in passport denial or revocation. Either a CP504 or LT11-level balance can meet this threshold.
What if I'm currently in a payment plan and received a CP504?
A CP504 while in an active payment plan may indicate that your plan defaulted due to a missed payment, or that the notice was generated before your plan was fully processed. Either way, verify your installment agreement status immediately — if it has defaulted, you need to act before the LT11 is issued.
Whether you're holding a CP504 or an LT11, the path forward is the same: understand your options, make the right decision for your situation, and move fast.
