1. Mainstay Filing: best for new owners who prefer to delegate
Annual $199; renewal $199; state fee extra
Mainstay Filing gives the best reading in Oklahoma: at $199 a year it completes three procedures (filing, registered agent, annual certificate) under one charge.
The three-year total is $200 above Oklahoma Registered Agent.co's, offset by the larger number of procedures it performs.
The annual certificate counts as performed, with Oklahoma's $25 billed without markup.

How a Oklahoma LLC is formed
Procedure1
Procedure 1: Fix the company name
A name held by another Oklahoma company can cause the filing to be returned; the business search at the Oklahoma Secretary of State gives the answer in advance.
TipA spare name saves a second round.
Procedure2
Procedure 2: Place a registered agent on record
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.
TipThe registered agent role is part of each ranked service.

Procedure3
Procedure 3: Compare filing alone with engaging a service
Filing alone costs the $100 state fee and nothing else. A service adds $199 and prepares the forms; the ranking gives the order.
Procedure4
Procedure 4: Send the Articles of Organization
the Oklahoma Secretary of State forms the LLC once it accepts the Articles of Organization (Form 0073) with $100.
Specimen: Observed at sos.ok.gov; entry dated October 2026
Procedure5
Procedure 5: Request the LLC's federal tax ID
The IRS issues EINs, not Oklahoma. Apply after approval and pass the number to the bank. The yearly price at Mainstay Filing covers this application.
Procedure6
Procedure 6: Draft the operating agreement
Even a single-owner Oklahoma LLC gains from a written operating agreement kept on file.
Procedure7
Procedure 7: Plan the second year
Recurrence is governed by the annual certificate ($25, every year, by anniversary date of the filing of the Articles of Organization).
