Colorado CPA Firm Renewal — What the Firm Itself Must File
Colorado 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 Colorado's firm-level filing is due.

Public Accounting Firm Registration
August 31, 2029
Firm registrations run on a triennial cycle, expiring August 31 board-wide -- a fixed date shared across all firms, not each firm's own anniversary. The Colorado Board states firm registrations 'expire on August 31, every three years,' but does not publish which specific years anchor the cycle.
Source of record (official records, not codified rule text)
Confirmed via Colorado Information Marketplace open-data register (data.colorado.gov, dataset 7s5z-vewr), aggregate query against the full active-firm register: what determines the cohort is each firm's own last-renewed date, not its issue/registration year -- issue year does not predict the cohort at all (every issue year 1971-2026 has members in both). As of 2026-09-21, a snapshot of a register that changes daily as firms renew or lapse (not a fixed count): 298 active firms are in the cohort due 2026-08-31, 1,187 are in the cohort set for 2029-08-31, of 1,485 active firm registrations total -- the 2026-08-27 snapshot recorded 526/959; the shift is firms in the 2026-08-31 cohort renewing into the next triennial term as that date passed, not a rule change (2026-09-21 re-verification).

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. See firm-tier pricing →
