IRS CP504: what it means and what to do

This is a Notice of Intent to Levy under Internal Revenue Code section 6331(d) and a final reminder that the IRS may levy your wages, bank accounts, or state tax refund for an unpaid balance. The IRS will also begin searching for other assets to levy. This summary is drawn from the IRS page for the CP504, last checked on October 13, 2026.

Why you received a CP504

  • The IRS has not received payment of your unpaid balance on one of your tax accounts

What to do

  1. Read the notice carefully for the amount owed and payment options
  2. Pay the amount shown immediately
  3. If you can't pay in full, pay what you can and set up a payment plan
  4. If you disagree, call the toll-free number on your notice

Deadline: Pay the amount shown on your notice immediately

If you disagree, or do not respond

Contact the IRS immediately to discuss it with a customer service representative. If you already paid or set up an installment agreement, call to confirm your account reflects it.

The IRS can file a Notice of Federal Tax Lien and levy your state tax refund. If a balance remains, you may get a notice about a hearing with the Independent Office of Appeals, and the IRS can then levy other property, including wages, bank accounts, business assets, personal assets such as your car and home, and Social Security benefits.

Get your records together first

Most notices come down to matching what the IRS has on file against your own records. Before you reply, pull the return the notice refers to, the bank statements and income forms for that year, and any payment confirmations. If your books are reconciled to the bank, that comparison takes minutes instead of days.
