Oklahoma Business Guide
How to Start a Business in Oklahoma
Everything you need to form your Oklahoma LLC, corporation, or sole proprietorship, with exact fees, timelines, and step-by-step instructions.
Oklahoma gives new founders a low cost of entry and a clear tax structure. An Oklahoma LLC costs $100 to form, the state has no general state business license, and there is no franchise tax for tax year 2024 and later. The corporate income tax is a flat 4%, and the top individual income tax rate is 4.5% from tax year 2026.
This guide covers every step of starting a business in Oklahoma, from choosing a legal structure to obtaining licenses.
