LLC Review Desk's 2026 picks for LLC services in Oklahoma, favorite first, are Mainstay Filing ($199), Oklahoma Registered Agent.co ($199) and OK Registered Agent.org ($199). Mainstay Filing is our favorite, because $199 a year covers the Oklahoma formation, a year as your registered agent and the annual certificate, and it renews at $199.

1. Mainstay Filing: best for formation, agent and annual certificate in one simple price
$199 a year, and the state fee goes on top
Our score

Our favorite is Mainstay Filing, because for one yearly price of $199 you get the Oklahoma filing, registered agent service and the annual certificate, then $199 at renewal.
When your plan renews, Mainstay files the annual certificate for you. Oklahoma charges $25 every year for it, and the date is anniversary date of the filing of the Articles of Organization. Mainstay passes the state's fee along at cost.
Over three years it costs $200 more than Oklahoma Registered Agent.co, and for us the extra things it handles are worth that.

Coming in second is Oklahoma Registered Agent.co, because the Oklahoma formation costs $199 over the state's fee, with the registered agent free the first year, and keeping the agent is $99 a year.
You get a street address in the state for your registered office, and any papers served on the company are scanned into your online account.
The annual certificate isn't part of its published price, so you send it to Oklahoma yourself every year.

We took each price from the company's own pages on November 12, 2026. On top of every row, Oklahoma charges a $100 filing fee, which isn't in these totals.
What decided the order
LLC Review Desk gives three-year cost 29% and filings in the price 29%, then divides 42% among renewal price, state fit and up-front totals. For Oklahoma, it came down to filings in the price.
In Oklahoma you'll need a report each year ($25 to the state). Mainstay's price includes that filing and Oklahoma Registered Agent.co's doesn't, which is why coverage beat Oklahoma Registered Agent.co's lower three-year cost.
You can read every criterion and weight on How we rank.
