Texas CPA Practicing in Oklahoma — What Actually Applies (and What Changes Nov. 1, 2026)
Oklahoma is a genuinely useful example of why "check the current rule, not what you remember" matters — because Oklahoma's own mobility rule is mid-transition. What applies to a Texas-licensed CPA working in Oklahoma today is not quite the same as what applies starting November 1, 2026.
The rule in effect right now, through October 31, 2026
Under the currently-operative version of 59 O.S. § 15.12A (in force since a 2023 amendment), Oklahoma grants full practice privilege to out-of-state CPAs — Texas-licensed CPAs included — with no notice, no fee, and no submission required, under a hybrid framework: licensees of NASBA-verified substantially-equivalent states are covered, and so is a catch-all provision presuming licensees of non-verified jurisdictions are ALSO substantially equivalent. Effectively, this functions as open CPA=CPA mobility today, even though the statute's own structure is a substantial-equivalency test rather than an individual-criteria one.
What changes on November 1, 2026
Oklahoma's 2026 UAA 9th-edition rewrite (HB 4317, signed May 5, 2026, no emergency clause) takes effect November 1, 2026 and replaces that substantial-equivalency scheme with true individual-criteria mobility: a valid out-of-state CPA/PA license, a passed Uniform CPA Exam, and one of three pathways met at initial licensure (a post-baccalaureate accounting degree plus 1 year of experience; a bachelor's plus 30 additional semester hours plus 1 year; or a bachelor's with an accounting concentration plus 2 years). If your original Texas licensure met any standard path to licensure, you should clear this without issue — but the underlying test itself genuinely changes, not just its wording. The no-notice/no-fee treatment for qualifying individuals carries forward into the new text.
Bringing a firm: registration only with an Oklahoma office
Firm-level mobility in Oklahoma is unusually explicit about this: the Board's own FAQ confirms full firm mobility since November 2023 "even if the work being performed is attestation-related," with registration required only if the firm has a physical office in Oklahoma (59 O.S. § 15.15). A firm with no Oklahoma office can perform attest work without registering, but only if it meets specific conditions — CPA-majority ownership standards, compliance with Oklahoma's peer/quality review requirement (§ 15.30), performing the work through an individual holding 15.12A practice privilege, and being able to lawfully perform that work in its home state. Miss any one of those conditions and the registration requirement comes back.
Two different triggers, same subsection: working in Oklahoma vs. living in Oklahoma
Mobility privilege covers out-of-state CPAs whose principal place of business stays outside Oklahoma. Two separate things can end that: taking employment with a public accounting firm located in Oklahoma, or engaging in the practice of public accounting in Oklahoma at all — either one, not just your firm's office physically relocating — starts a 120-day clock to file for a reciprocal certificate/permit (OAC 10:15-21-1(b)). That's a broader trigger than "your firm relocates": taking a job with an Oklahoma-based firm while you personally still live elsewhere starts the same 120-day clock.
Separately, and this is easy to miss: as of September 15, 2026, the same subsection, OAC 10:15-21-1(b), also requires an Oklahoma certificate for anyone who personally resides in Oklahoma and holds themselves out as a CPA — regardless of where their firm office stays. That means a Texas CPA who moves to Oklahoma personally but keeps working for a Texas-based firm office (and doesn't otherwise work for an Oklahoma firm or practice in Oklahoma) doesn't get to rely on principal-place-of-business mobility at all: the residency rule applies to them directly, on top of — not instead of — the employment/practice trigger above. Those are two independent tests in the same subsection — where you work or practice, and where you yourself live — and as of this rule change, either one alone can require an Oklahoma certificate.
The honest caveat: this page describes two different rule states on either side of a real statutory deadline, sourced to 59 O.S. §§ 15.12A, 15.15, 15.15C, and 15.30 as amended by the 2023 and 2026 acts, plus OAC 10:15-21-1 as amended effective September 15, 2026. It's general orientation, not a determination for your specific attest/non-attest engagement mix. For your actual situation — especially anything time-sensitive around the November 2026 changeover, or if you're personally relocating to Oklahoma — run it through our Practice Privilege Check tool or confirm with the Oklahoma Accountancy Board directly. And keep your own Texas renewal on track while you're at it — it's due annually by your own birth month, easy to lose track of. Check your Texas renewal date here.
