CP503, CP504, CP90:
What Each Notice Means
and What to Do Right Now
These three notices are not the same warning repeated. Each one is a step closer to the IRS seizing your wages, freezing your bank account, or taking property. The window to stop it gets shorter with each notice — and CP90 starts a 30-day clock before levy authority becomes active. Omni Tax Help has managed over $203 million in IRS tax liability for thousands of clients nationwide.
The IRS Collections Escalation — Where You Stand
The IRS does not move straight to seizing your wages or bank account. It follows a legal process — a sequence of notices that escalates from reminder to final warning. Understanding which notice you have tells you exactly how much time you have and what the IRS can do next.
Missing the deadlines in this sequence does not pause the clock. It accelerates enforcement. Here is what each notice means and what action is required at each stage.
The CP503 is the IRS's second contact after the CP501. It means the IRS has not received payment or a response to the initial notice. The tone escalates — the language is more direct, and the IRS is signaling that collections are the next step if nothing changes.
What to do: Do not ignore it. A response — whether it is an installment agreement, a hardship claim, or a dispute — stops the escalation. Ignoring CP503 triggers CP504. Call Omni today to determine the right response for your specific balance and situation.
The CP504 is labeled "urgent" — the IRS means it. At this stage, the IRS has the authority to levy your state tax refund immediately. It is also their final notice before they can issue a Notice of Intent to Levy on other assets. Your wages, bank accounts, and property are now in the enforcement queue.
What to do: Act within days, not weeks. The window between CP504 and full levy authority is narrow. Getting into a formal resolution — an Installment Agreement, an OIC, or a CNC hardship claim — can stop enforcement. Omni files Form 2848 and takes over communications with the IRS immediately.
This is the last notice before the IRS can legally seize wages, empty bank accounts, and take property. The CP90 or LT11 grants you a 30-day window to request a Collection Due Process (CDP) hearing. Filing within that window legally pauses most levy action while your appeal is reviewed.
If you have received a CP90 or LT11, call us today. Missing this 30-day window removes the CDP protection entirely. Once it closes, the IRS can proceed with levy action without further notice. Call (800) 707-8065 immediately.

Not the final final — but nearly. CP504 authorizes the IRS to levy your state tax refund immediately. It is the final notice before the IRS issues the CP90 or LT11, which is the actual Final Notice of Intent to Levy that starts the 30-day CDP hearing window. If you have a CP504, the next step is CP90 unless you act first.
The CP90 or LT11 is the IRS's Final Notice of Intent to Levy. It grants you 30 days to request a Collection Due Process (CDP) hearing. Filing within that window legally pauses most levy action while your appeal is reviewed. Missing the 30-day deadline removes this protection entirely and the IRS can proceed with collection.
Yes — if you act within the 30-day window by filing for a CDP hearing, or by getting into a formal resolution before the window closes. Even after the window closes, levy releases are available through Installment Agreements, CNC status, OIC submission, or hardship claims. The earlier you act, the more options remain. See our IRS Levy Release page for the full process.
They are functionally the same notice — both are the IRS's Final Notice of Intent to Levy with a Right to a Hearing. CP90 is typically mailed to your address on file; LT11 is often used for wage levy situations. Both start the 30-day CDP window and both require the same immediate response.
Contact us today or call (800) 707-8065. We respond same day. Available Monday–Friday, 8 AM–5 PM ET.
Understand the full IRS escalation sequence: The CP503, CP504, and CP90 are steps in the IRS Collections Process that leads from first notice to levy. Understanding the full timeline helps you act at the right moment.
If you received a CP90 or LT11, you have 30 days to file for a CDP hearing. Missing this deadline removes a critical layer of protection.
