1. Oklahoma Tax Commission — Sales Tax Permit

   Required for any vendor selling taxable goods or services in Oklahoma. Register with the Oklahoma Tax Commission online through OkTAP. Oklahoma levies 4.5% state sales tax; cities and counties add their own local rates on top, so the combined rate depends on the delivery address — look it up on the OTC rate charts rather than assuming a statewide maximum.

1. Oklahoma Construction Industries Board — Plumbing Contractor License

   Plumbing contractors in Oklahoma must hold a Plumbing Contractor License from the Construction Industries Board, obtained by passing the CIB examination after progressing through apprentice registration and journeyman licensure. There is no requirement to designate a separate 'Master Plumber' on staff — the contractor's own license satisfies the requirement. An active contractor must maintain a $5,000 corporate surety bond payable to the Board and liability insurance of at least $50,000.

2. City of Tulsa Business Licensing (category-specific)

   The City of Tulsa does not require a general business license. The Finance Department's Business Licensing office issues licenses only for enumerated categories: alarm permits, animals (hobbyist exemption), beverage certificate of compliance, chauffeur, coin-op, commercial animal establishment, food and liquor, hotel, loading zone, outdoor seller, pawnbroker, recreation center, sexually oriented business, short-term rental, and taxi and paratransit. Businesses outside these categories — real estate agents, tutors, personal trainers, cleaning services and the like — need no city business license, only an Oklahoma Tax Commission sales tax permit if they sell taxable goods or services, plus zoning compliance and any required Certificate of Occupancy.
