Arizona CPA licenses must be renewed annually on or before December 31st each year (Arizona Revised Statutes § 32-728). The renewal fee is $225 for a standard license. To renew, you must complete and submit the renewal form to the Arizona Board of Accountancy by the deadline, along with proof of completion of 40 hours of continuing professional education (CPE) during the prior calendar year.

Of the 40 required CPE hours, at least 20 hours must be in accounting, auditing, or taxation. The remaining 20 hours may be in any business-related subject. You must obtain CPE from providers approved by the Arizona Board of Accountancy or NASBA. Online renewal is available through the Arizona Board of Accountancy website (azaccountancy.gov). If you miss the December 31st deadline, you cannot legally practice as a CPA in Arizona until your license is renewed.

Operating an accounting firm or providing accounting services without proper CPA licensure in Arizona constitutes a violation of Arizona Revised Statutes § 32-730, which prohibits the practice of public accounting by unlicensed individuals. Violations result in civil penalties of $500 per violation per day of continued unlicensed practice. The Arizona Board of Accountancy can issue cease-and-desist orders requiring immediate termination of unlicensed activities.

Criminal penalties may also apply under Arizona Revised Statutes § 32-732 for fraudulent use of the CPA title or practice. Individuals found guilty of criminal violation face class 5 felony charges with potential imprisonment and fines up to $2,500. The Board discovers violations through consumer complaints, periodic audits of accounting firms, and referrals from law enforcement or professional organizations.

Operating without licensure also has serious insurance implications. Professional liability insurance (errors and omissions coverage) is typically unavailable for unlicensed practitioners. Clients may pursue civil lawsuits directly against you without insurance protection, exposing you to personal liability for all damages. Additionally, the firm may face suspension or revocation of its registration, preventing all owners from conducting business as a licensed accounting firm. Penalties may include restitution to affected clients, injunctive relief, and potential referral to state attorneys general for additional enforcement.
