Check the date and instructions on your letter

Treat the response as time-sensitive. CP504 does not by itself describe every hearing right that may apply to later collection notices.

Why you may have received CP504

Collection steps and available options depend on your account and the notice sequence. A payment, payment plan, or disagreement should be addressed through the IRS instructions rather than ignored.

What to check now

  1. 1Confirm the tax year, amount, notice date, and payment history.
  2. 2Read the payment, payment-plan, disagreement, and appeal instructions on every page.
  3. 3If you already paid or believe the balance is wrong, contact the IRS using the number on the notice.

Read the IRS source

The official IRS page has the full instructions, payment or verification links when applicable, and contact information. Always compare it with the version of the letter you received.
