Starting an LLC in Oklahoma, step by step
Step1
Step 1: Check your name is available
Search the register kept by the Oklahoma Secretary of State first. If the name is taken, choose another before you file.
TipPick a spare name too, in case the first is taken.
Step2
Step 2: Name a registered agent
Every LLC must name a registered agent with an in-state street address. The LLC itself, an Oklahoma resident, or a corporation, LLC or partnership formed in Oklahoma or qualified there.
The address has to be a street address in Oklahoma, at a business office that is open during regular business hours. P.O. boxes are not accepted.
TipEvery service in our picks can act as your registered agent.

Step 6: Put an operating agreement in writing
Even with one owner, a written operating agreement for the Oklahoma LLC is worth having in your records.
Step7
