Forming an LLC in Oklahoma costs $100 to file Articles of Organization with the Oklahoma Secretary of State, with online approval through the SOS Business Filing portal in 1–2 business days. The annual certificate is $25, due in the LLC's anniversary month. Oklahoma has no LLC franchise tax (the corporate franchise tax doesn't apply to LLCs taxed as pass-through) and a graduated individual income tax topping out at 4.75%. Combined sales tax averages 8.99% — among the higher in the U.S. — due to high local rates. Oklahoma's economy is anchored by oil and gas (Tulsa is historically known as the "Oil Capital of the World"), aerospace and defense (Tinker Air Force Base depot in Oklahoma City is one of the largest aircraft maintenance facilities in the U.S.), and agriculture. For founders in energy, aerospace, or ag-related businesses, Oklahoma offers reasonable cost and meaningful industry depth.
