Illinois CPA Firm Renewal — What the Firm Itself Must File

Illinois firm registration/permit — not individual license renewal

A CPA firm's own registration or permit to practice renews separately from any individual staff CPA's license — and it's usually the filing that falls through the cracks, because it belongs to whoever handles firm admin, not to a specific licensee tracking their own renewal. Here's exactly when Illinois's firm-level filing is due.

Firm license

November 30, 2027

Firm licenses expire November 30, on a 3-year cycle (68 Ill. Admin. Code 1420.80(b)) -- the same rule section that governs individual renewals, just a different subsection. The rule codifies the recurring month/day and the 3-year interval, but does not itself pin a specific anchor year for the firm track.

Source of record (official records, not codified rule text) Confirmed via Illinois IDFPR's public open-data license register (data.illinois.gov, dataset pzzh-kp68): active "Public Accountant Firm License" records show expiration 11/30/2027, unchanged from the 2026-07-17 check and confirmed again 2026-07-30. see the records →

Always confirm with the official state board before relying on this date. License requirements and deadlines can change.

Tracking this for more than one firm, or want someone else watching it?

Any individual CPA at your firm can already get free renewal reminders for their own license. What Deadline-Radar's firm tier adds is the view your admin doesn't get from 20 separate free sign-ups: one place to see the whole roster's status — including this firm-level filing — not 20 inboxes to hope someone's watching.
