IRS Notice · CP501

Got an IRS CP501 Notice? Here Is What It Means.

A CP501 is a reminder that you still have an unpaid balance after the first bill. It is the second contact in the collection process. You are still early, and every option is still open.

The short version. A CP501 is a balance due reminder. The IRS sent the first bill (a CP14), did not receive payment, and is reminding you that the balance is still there and growing with penalties and interest. It is not an enforcement notice. Nothing is being levied.

What a CP501 is and is not

A CP501 is a nudge, not a seizure. It matters mostly because of what comes after it if you keep waiting.

A CP501 does

  • Remind you the balance is still unpaid.
  • Keep adding penalties and interest.
  • Move you one step along the collection stream.
  • Give you payment and contact options.

A CP501 does not

  • Levy your wages, bank account, or refund.
  • File a tax lien by itself.
  • Remove your right to set up a payment plan.
  • Mean you are out of time to act.

What you can do about it

You are still early enough that the simple paths are open. Each is something you request and the IRS reviews. None is guaranteed.

This is one reminder. There may be more on your account.

A CP501 shows one balance. Your full IRS account can hold other years and other issues. Send your case in for a free review and we will tell you exactly where you stand.
