Pick a structure (sole proprietor or LLC)
Most Oklahoma owners start as a sole proprietor (free, no filing) or form an LLC for liability protection. The LLC filing fee is about $100, and formation typically takes about 1–2 business days online. Confirm the current fee on the state site before you pay.
Name a registered agent
If you form an LLC or corporation, Oklahoma needs a registered agent with a physical in-state address. You can be your own agent if you're available during business hours, or hire a service for about $100–$150/year.
Get your EIN from the IRS
An Employer Identification Number is free from the IRS and takes a few minutes online. You need it to open a business bank account and to hire.
Register for Oklahoma taxes
Oklahoma has a state sales/use tax and has a state income tax. Oklahoma's Annual Certificate is $25 and due on the formation anniversary.
Confirm local licenses and permits
Oklahoma rarely issues a single statewide "business license" — most licensing is by city or county, plus profession-specific licenses. Check your city and your trade.
Open a business bank account and get insurance
Keep business and personal money separate from day one. General liability insurance is the baseline; some contracts also require a bond.
Put the ongoing report on your calendar
