Colorado CPA License Renewal: Two Different Clocks for Individuals and Firms

Colorado runs individual CPA certificates and firm registrations on genuinely different clocks — not just a different date, but a different cycle length. Here's exactly how both renewal tracks work, sourced to the Colorado Board of Accountancy's own records and the state's codified rules.

Individuals: November 30, every odd-numbered year

Every individual CPA certificate in Colorado expires November 30 of odd-numbered years — one statewide date, not birth-month or cohort-based. It applies uniformly regardless of when your certificate was first issued: sampling active licenses issued anywhere from 1977 to 2026 in the state's own open-data register, every one shows the same 11/30/2027 expiration. The one exception is for brand-new certificates — if yours is issued within 120 days of an upcoming November 30, the Board bumps you to the following cycle rather than making you renew almost immediately.

Firms run on a separate, longer cycle: August 31, every three years

Public accounting firm registrations are a different clock entirely. They expire August 31, once every three years, board-wide — a fixed date shared by every registered firm, not each firm's own anniversary of registering. The cycle runs 2023 → 2026 → 2029, so with the August 31, 2026 deadline now behind us, the next firm-registration deadline for every Colorado firm is August 31, 2029. One detail worth knowing if you're ever reconciling a firm's record: what places a firm in a given three-year cohort is the date it most recently renewed, not the year it first registered — a firm registered in 1985 and one registered last year can sit in the same cohort. The firm-registration page has the full sourcing for that.

CPE: 80 hours per two-year period, accrued by the quarter

Colorado's CPE reporting period runs from January 1 of an even-numbered year through December 31 of the following odd-numbered year. The rule doesn't actually say "80 hours" — it says a certificate holder must complete ten hours of CPE for each full quarter of active licensure during the period (3 CCR 705-1, Rule 1.9(G)(2)), which works out to 80 for anyone active the whole two years, and proportionally less for a certificate that was active for only part of it. There's no separate single-year minimum the way several other states impose one; the requirement simply accrues quarter by quarter.

The part that trips people up: that CPE reporting deadline — December 31 — lands a month after your actual certificate renewal date of November 30 in the same year. Your license comes up for renewal before the CPE window for that same cycle formally closes, and renewal requires attesting that you've complied with the CPE rule (Rule 1.9(G)(3)). Don't assume the two dates are the same one.

Inside the 80: four hours of ethics, and a Colorado-specific piece of it

Of the 80 hours, four must be in ethics — and up to two of those four may be satisfied with a Colorado Rules and Regulations (CR&R) course specifically (Rule 1.9(G)(2)(b)). CR&R has a precise definition in the rules: CPE covering Colorado's own accountancy statute (C.R.S. § 12-100-101 through § 12-100-130 and § 13-90-107(1)(f)) and the Board's own rules and policies, following a content outline the Board publishes (Rule 1.1(B); Rule 1.10(H)). This is a Colorado-specific carve-out, not something every state builds into its ethics hours — worth flagging for anyone who has renewed in another state and assumes "four hours of ethics" means any ethics course qualifies for all of it.

A discrepancy worth knowing: which rule number is the CPE rule?

If you look this up yourself you'll find the same requirement cited three different ways — "Rule 1.6," "Rule 1.9," "Rule 1.10" — and they aren't all wrong, just from different years. Colorado re-adopted and renumbered the entire 3 CCR 705-1 effective June 30, 2022. The clause that used to sit at Rule 1.6(G)(2) is now Rule 1.9(G)(2); the CPE rule proper moved from 1.7 to 1.10; and the old 1.9 (professional conduct) is now 1.12. The wrinkle is that the Secretary of State's site still serves the pre-2022 edition under its old document ID, so a citation to "1.6(G)(2)" resolves to a real page and reads word-for-word correct — it's just superseded numbering. We publish the current edition's numbering above, and we caught our own citation pointing at the old one while checking this guide.

If you miss November 30

There is a sixty-day grace period from the expiration date within which the certificate can still be renewed by paying the renewal fee plus a late fee, and the Board won't discipline you for holding out or practicing during those sixty days (Rule 1.9(J)(1)). After the grace period, an expired certificate holder can't hold out or perform any service that requires an active certificate. And the rules are explicit that not receiving a renewal notice doesn't relieve you of the obligation to renew (Rule 1.9(B)(2)(c)) — the notice is a courtesy, not the deadline. The dollar amount of the late fee isn't set in the rules themselves (it's on the licensing portal's fee schedule), so we don't publish a figure for it.

Bottom line: if you're an individual Colorado CPA, mark November 30 of every odd-numbered year. If your firm holds its own registration, that's a separate August 31 date on a three-year cycle — next up, 2029 — and it doesn't track your personal renewal. Either way, budget 80 CPE hours per two-year period with four in ethics (up to two of them Colorado-specific CR&R), and remember your CPE window runs a month past your license date, not alongside it. Set a reminder for your Colorado deadline here so both clocks work for you instead of quietly running past you.
