IRS letters

CP501. First reminder.

The IRS says CP501 means there is a balance due on one of your tax accounts. The notice explains how much it shows, when payment is due, and payment options.

General information from the Law Office of Alexander Powell, PLLC. It is not legal advice, and it is not a substitute for the notice itself.

On the paper

Locate the tax period, current balance, and the date by which the IRS asks you to pay or respond.

Find the date printed on your notice or letter. The paper notice and the current official IRS instructions control, even where this page differs.

General next steps

  1. Compare the notice to your return, prior payments, and any earlier IRS correspondence.
  2. If you agree with the amount, review the official payment options.
  3. If you disagree, follow the notice-specific instructions instead of sending sensitive information through a website.

Timing

The IRS says to pay by the due date shown on the notice. The notice in your hand controls.

What this page cannot tell you

This page cannot verify your IRS account, payment history, or whether the balance is accurate.

Official sources

If anything on this page differs from your notice or from current IRS instructions, follow the notice and the IRS.

Questions after reading the letter?

You can ask the Law Office of Alexander Powell, PLLC to consider a consultation about any IRS or tax letter. Requesting a consultation does not make Mr. Powell your lawyer, provide legal advice, or protect a deadline. Representation begins only after a conflict check, after the firm agrees to the matter, and after both sides sign a written engagement agreement.
