IRS CP501 Notice Explained: What It Means and What To Do

If you received an IRS CP501 notice, it means you still have unpaid taxes. CP501 is a reminder notice sent after the IRS has already issued a CP14 bill and has not received payment.

What Is an IRS CP501 Notice?

The CP501 notice is a reminder that you have a balance due on your tax account. It is not the first notice, but it is still considered an early-stage collection letter.

Why Did I Get a CP501 Notice?

  • You did not pay the amount listed on CP14
  • Your payment has not been processed
  • Interest and penalties have increased your balance

How Serious Is CP501?

CP501 is more serious than CP14 but still not a final warning. It means the IRS expects payment soon.
