Your Oklahoma LLC name must contain "Limited Liability Company," "LLC," or "L.L.C." Restricted words like "Bank," "Insurance," or "Trust" require additional licensing. The name must be distinguishable from existing business entities in Oklahoma.

Oklahoma LLCs are pass-through entities by default. Members pay Oklahoma individual income tax on their share of profits (top rate of 4.75%). Oklahoma does not impose a franchise tax on LLCs. The Annual Certificate costs $25. Oklahoma does not charge late fees for delinquent Annual Certificates, but your LLC loses good standing status.

LLC vs. other structures in Oklahoma

Oklahoma has affordable LLC costs: $100 to file and just $25/year. The 4.75% top income tax rate is moderate. Total first-year cost is $125. Oklahoma is a solid, affordable choice for LLC formation with no major downsides.

• •File an Annual Certificate on the anniversary of formation — $25 fee
• •Maintain a registered agent with a physical address in Oklahoma at all times
• •Keep your operating agreement current and update it when membership changes
• •File Oklahoma state income tax returns for all members receiving pass-through income
• •Renew any local business licenses or permits as required

Oklahoma offers a reasonable cost structure for LLCs. The $100 filing fee is competitive, and ongoing costs are manageable. If you operate in Oklahoma, forming your LLC here makes the most sense.

In general, you should form your LLC in the state where you physically live and conduct business. Forming in a "tax-friendly" state like Wyoming, Delaware, or Nevada sounds appealing, but if you operate in Oklahoma, you will still need to register as a foreign LLC there — paying fees in both states.

An LLC is almost always a better choice than operating as a sole proprietorship because of the personal liability protection it provides. However, if your LLC is highly profitable, you should talk to a CPA about electing S-Corp tax treatment to potentially reduce your self-employment tax burden.
