Plan on the annual certificate ($25, annual). It falls due anniversary date of the filing of the Articles of Organization; put the date in your calendar.
The bottom line adds up the filing fee, the reports for years two and three and the minimum tax if there is one. A cost with no set price, like a newspaper notice, is left out of the sum.
A few more
Can I serve as agent myself?
In most cases, yes. Check who qualifies and which address counts, then you can do it yourself.
Where must the agent be?
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.
After three years, what has each cost?
Three-year costs are Mainstay Filing, $447; Oklahoma Registered Agent.co, $297; OK Registered Agent.org, $297
What are your sources?
State side: Oklahoma's published fee schedules and forms. Service side: the prices each company lists.
Does the law require a service?
Not at all. Owners can file with the state directly; a service is there to save you the work and to act as agent.
Which registered agent should I hire in Oklahoma?
Mainstay Filing first: $149 a year is its fee in this state and every other. Oklahoma Registered Agent.co and OK Registered Agent.org follow.
