Second Reminder: Balance Still Due (CP503)
This is a second, more urgent reminder that your tax balance is still unpaid.
Why you might get this
- You didn't respond to earlier notices (like CP14 or CP501).
- A balance from a past-due tax year is still open.
- Penalties and interest are still growing on what you owe.
The deadline
You have a short window, about 10 days, to pay or arrange a plan before the IRS escalates to a levy warning.

- Act quickly — this is a shorter deadline than earlier notices.
- Pay the balance in full if you can, online, by phone, or by mail.
- If you can't pay in full, set up a payment plan (an installment agreement) right away.
- If you think the balance is wrong, call the number on the notice immediately.
What happens if you ignore it
The IRS sends a CP504, which is its notice of intent to seize (levy) your state tax refund and to begin pursuing other assets.
CP503 is the second reminder: CP501 → CP503 → CP504 → LT11/Letter 1058.
What the IRS CP503 notice means for you
A CP503 is the second reminder the IRS sends about an unpaid balance, and the tone has shifted. Earlier notices were nudges; this one is a warning. It means one or more previous notices (a CP14, then a CP501) went unanswered, and the IRS wants a response soon.
The window here is short — often about 10 days — so the CP503 is a signal to stop putting it off. Penalties and interest keep compounding, and the next letter in line, the CP504, starts the levy process by targeting your state tax refund.
Even at this stage, you have real options and nothing has been seized yet. If you can pay the balance, paying now ends the escalation. If you can't, setting up an installment agreement keeps your account in good standing and stops the notices from advancing. If you genuinely believe the amount is wrong or already paid, call right away — but don't simply ignore the letter hoping it resolves itself.
The single most important move is to respond before the short deadline passes. That's what keeps a CP503 from turning into a levy warning.
