A CP503 is the second reminder about an unpaid balance. It comes after a CP14 and a CP501 for the same tax year.
The wording is firmer than the first reminder and the total is usually larger, because penalties and interest keep accruing while the balance sits.
It also signals where the account is heading. A CP503 sits just before CP504, the notice that describes the IRS's intent to take assets such as a state tax refund.

RE: Notice CP503, Second Reminder, Tax Year 2023
To Whom It May Concern:
I am writing in response to the CP503 notice dated [Date] regarding a balance of $2,318.90 for tax year 2023.
1. Basis for this response. The balance shown does not reflect the payment of $500.00 posted on [Date], nor the abatement request submitted on [Date]. Copies are enclosed.
2. Request. I ask that the account be reviewed and that an updated statement of account be issued for tax year 2023 before further collection steps are taken.

It is the second reminder that a tax year balance remains unpaid. It restates the amount with updated penalties and interest.
The notice prints a date, commonly around ten days out. Our tool reads that date off your specific notice.
The next notice in the sequence is usually a CP504, which describes the IRS's intent to seize a state tax refund or other assets.
Yes. Responses at this stage typically address a disputed figure, a payment already made, or a proposed arrangement. Our tool drafts that letter for you.
It is more urgent than the first reminder because it is the last notice before the intent-to-levy sequence begins.
A CP503 is a reminder, not a levy notice. The notices that describe levy action are CP504, LT11, and Letter 1058.
A reminder notice that a balance from an earlier bill is still unpaid.
