I got a CP503 notice from the IRS

If you got a notice from the IRS, don’t worry. We’ll do our best to help you figure out what to do next.

The CP503 notice means that the IRS hasn’t heard from you and you still have an unpaid balance on one of your tax accounts. 

Read your notice carefully and make your payment by the due date. Go to the IRS to find out more about your payment options. You can also contact the IRS if you have additional questions.
