IRS notice guide
Which IRS notice did you get?
The notice number is in the top or bottom right corner of the letter. Find yours below to see what it means, how urgent it is, and your options before the deadline.
Common IRS notices and what they mean
Unpaid balances usually move through these notices in sequence. Each one leaves fewer options and less time than the one before, and the IRS doesn't always send every step.

CP501First reminder
Moderate urgencyThe balance from your first bill is still unpaid, with penalties and interest added.
CP503Second reminder
Moderate urgencyA firmer reminder that warns of a possible federal tax lien.
CP504Notice of intent to levy
High urgencyThe IRS can take your state refund and is preparing further enforcement.
LT11 / 1058Final notice of intent to levy

Letter 3172Federal tax lien filed
