Licenses & Permits in Oklahoma

General Business License

Oklahoma does not have a statewide general business license. Businesses must register their entity with the Oklahoma Secretary of State and register with the Oklahoma Tax Commission for sales and use tax purposes. Many Oklahoma cities require local business licenses — Oklahoma City, Tulsa, Norman, and other municipalities have their own licensing programs. The Oklahoma state portal at oklahoma.gov provides business registration resources.

Frequently Asked Questions

Starting an accounting firm typically requires a low-to-mid five-figure investment, covering CPA licensing, professional liability insurance, tax software, and initial marketing. Home-based practices can launch at the lower end of that range.

You don't need a CPA license to offer bookkeeping services, but you must be a licensed CPA to offer auditing services or sign tax returns as a paid preparer. Using 'CPA' in your firm name typically requires a licensed CPA as the majority owner.

Drake Tax (https://www.drakesoftware.com/products/drake-tax/) is popular for solo practices, billed as an annual subscription scaled to feature tier. Lacerte and ProSeries are preferred by larger firms. UltraTax is common at mid-size firms. All handle individual and business returns.

A solo CPA charging a healthy three-figure hourly rate can be profitable with a few dozen regular business clients or roughly 100-150 individual tax clients. The key is mix — monthly bookkeeping retainers provide predictable revenue, while tax season creates seasonal peaks.
