CP504 final notice? Build the levy-risk file before you call or pay.

A CP504 notice is more serious than a routine balance reminder. The useful response file connects the notice date, tax year, balance, payment options, state refund levy risk and any hardship or dispute evidence.

Direct answer

IRS CP504 guidance says the notice is a final reminder that the IRS intends to levy wages, bank accounts or a state tax refund because an unpaid balance remains.

Use this checklist to organize evidence before contacting the IRS or a tax professional. It is not tax, legal or financial advice.
