IRS CP501 Notice — What It Means and What To Do
Receiving an IRS CP501 notice can feel overwhelming. This guide explains what the notice means, what the deadlines are, and what options exist for penalty relief.
Response Deadline
The IRS expects a response within 21 days. Acting before this deadline preserves all relief options and prevents escalation to the next collection stage.
What This Notice Means
The IRS is reminding you of an unpaid balance on your tax account. This is the first follow-up notice sent after the initial CP14 balance-due notice went unanswered.

Frequently Asked Questions
What is the difference between a CP14 and a CP501?
A CP14 is the initial balance-due notice. A CP501 is the first reminder sent when the CP14 balance remains unpaid. The amounts may differ due to additional accrued interest and penalties.
How long do I have to pay a CP501?
The notice typically requests payment within 21 days. Failure to respond leads to further collection notices.
Can I still set up a payment plan after receiving a CP501?
Yes. You can apply for an installment agreement or short-term extension through IRS.gov or by calling the number on the notice.

What comes after a CP501 if I do not pay?
The IRS will send a CP503 (second reminder) and eventually a CP504 (Notice of Intent to Levy). Each notice escalates the urgency of collection.
Will the IRS levy my bank account based on a CP501?
No. The CP501 is a reminder notice only. The IRS must issue a CP504 or LT11 before taking levy action.
Can penalties still be abated at this stage?
Yes. Penalty abatement through First Time Abate or reasonable cause can be requested at any point before or after payment.
