IRS Notice Library — What Every Collection Notice Means

What This Library Covers

Every IRS collection notice follows a set sequence — first reminder, second reminder, then formal intent-to-levy warnings. This library explains what each notice code means, your actual deadline, and what happens if you miss it. Sourced directly from IRS.gov.

Notices By Collection Stage

Early reminders (30–60 days out): CP14 · CP501 · CP503

Intent to levy / seize property: CP504 · CP504B (Business) · CP90 · LT11 / Letter 1058

Installment agreement in danger: CP523

Passport at risk: CP508C · CP71C

Return discrepancy: CP2000

If You Received Any of These Notices

A CP504, CP90, LT11, or CP523 notice means the IRS believes it can start seizing assets soon. If a lien is already filed, most banks will not touch your file. Financing that pays the IRS directly can stop enforcement before a levy hits your accounts.
