Registering a foreign LLC in Oklahoma: fee, form and office
Registration goes to the Oklahoma Secretary of State, Business Filing Department on the Application for Registration (Foreign Limited Liability Company) (SOS Form 0081). The state fee is $300. Along with the form, Oklahoma expects certificate of good standing, existence or fact, no older than 60 days when you file.
Each year after that, the company files the annual certificate for $25, due anniversary of the registration date.
What to have ready before you file
- Certificate of good standing, existence or fact, dated within 60 days of filing.
- The company's exact legal name and its formation date in the home state.
- A registered agent at a street address in the state. Every company on this shortlist can be that agent.
- Payment of the $300 state fee with the filing.
- A reminder in your own calendar for the annual certificate and its $25 fee.
