Layer by layer

How much does forming an LLC cost in this state?

Your bill has two parts: $100 for the filing and, optionally, $199 for first-year help.

State fees for years one through three stack up to $150. sos.ok.gov holds the original, confirmed October 2026

Which form is inside the filing, and where does it go?

The Articles of Organization (Form 0073) is the filing, and the Oklahoma Secretary of State is where it goes. Approval creates the LLC.

sos.ok.gov holds the original, confirmed October 2026

Is a registered agent required?

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.

sos.ok.gov holds the original, confirmed October 2026

What comes after the LLC is formed?

Underneath it all, one filing repeats: the annual certificate, every year, at $25 each time. The state phrases its deadline like this: anniversary date of the filing of the Articles of Organization.

sos.ok.gov holds the original, confirmed August 2026

Can I file it myself instead of hiring a service?

Nothing stops you. Without a service, your three-year bill is the state's $150.

That $397 to $597 over three years is the price of handing off the paperwork and the agent role.

What put number one on top?

Mainstay Filing is strongest on what is inside the price, a layer worth 29% of the score.

Five layers set the order: total across three years (34%), what is inside the price (29%), price laid out in the open (14%), how the renewal behaves (12%) and how far it reaches (11%).

The layer that decides it: the annual certificate sits inside the first pick's price, while OK Registered Agent.org leaves it with you.
