How CPA License Renewal Works in Illinois: Dates, CPE, and Firm Registration

Illinois runs individual licenses and firm licenses on the same 3-year cycle length, but different expiration months and a different anchor-year picture — and its CPE rule bundles in a training requirement that's easy to miss because it isn't labeled "ethics." Here's exactly how each piece works, sourced to Illinois's own administrative code.

Individual CPA license: every 3 years, ending September 30

Illinois individual CPA licenses run on a 3-year cycle expiring September 30 (68 Ill. Admin. Code 1420.80(a)). The currently confirmed cycle ends September 30, 2027. Confirm your own next Illinois CPA renewal deadline here.

Firm licenses: same rule, different month — and a real data gap worth knowing about

Firm licenses are governed by the same rule section, just a different subsection (68 Ill. Admin. Code 1420.80(b)): a 3-year cycle expiring November 30. What the rule text doesn't pin down is a specific anchor year for the firm track the way it does for individual licenses. A 2021 IDFPR variance did extend that cycle's firm-license expiration from November 30, 2021 to January 31, 2022 — but that's a one-time administrative order, not codified rule text, so we're not projecting a current cycle from it. If you hold a firm license, confirm your exact renewal date with IDFPR or on your permit itself rather than assuming it lines up with any individual license at the same firm.

CPE: 120 hours per 3-year period — checked at renewal, not annually

Illinois requires 120 CPE hours per 3-year renewal period, including at least 4 hours of professional ethics (68 Ill. Admin. Code § 1420.70(a)(1)). Unlike states that check a chunk of your CPE every single year regardless of license-cycle length, Illinois's rule states no separate annual minimum — the 120-hour count is measured against the 3-year period as a whole.

The requirement that's easy to miss: it isn't labeled "ethics"

Illinois also requires a 1-hour sexual harassment prevention training — but the rule keeps this as its own distinct category, separate from the 4-hour ethics requirement. It's easy to read "4 hours of ethics" as the whole compliance picture and miss this second, smaller, differently-labeled requirement entirely. Both are real, both are required, and they don't count toward each other.

Bottom line: if you're an Illinois CPA, track two things separately — your license's 3-year cycle (individual ending September 30, firm ending November 30 with no assumed anchor year), and your 120-hour/3-year CPE count, remembering the 1-hour harassment-prevention training is a second, separate line item from your 4 ethics hours. Set a reminder for your Illinois deadline here so none of these get missed.
