IRS Notice CP501

You have unpaid taxes

Each year, millions of taxpayers are faced with a tax bill they can't afford to pay. If the IRS sends you a notice about unpaid taxes, the first thing to do is make sure the amount is correct. Let the experts at H&R Block research your balance and make sure you don't wind up paying any more than required.

What happened?

  1. The IRS sent you a notice indicating you have a tax balance due, but the IRS never got a response.
  2. The IRS sent the CP501 notice to request payment. If you don't pay the full balance of due taxes within 10 days, you will be charged more penalties and interest.

  • Depending on your situation, you might qualify for one or more payment arrangements with the IRS. We'll look into your tax situation and show you your best options.
  • If the IRS has assessed penalties, we'll see whether you qualify to have them removed.
