Who we would hire in Oklahoma

Three-year cost and the number of steps a price takes off your list weigh the most; the grading page lists all five criteria.
First choice

1. Mainstay Filing: best for one bill for filing and upkeep

Annual price $199, renewal price $199, state fee extra

Mainstay Filing earns the highest mark because you pay $199 each year and the formation, the registered agent service and the annual certificate all get done.

Oklahoma Registered Agent.co is $200 less across three years; handling more of the lesson's steps earns this one the higher mark.

You never file the annual certificate yourself; only the $25 state fee is added.

What the price covers

  • Filing with the state
  • Registered agent for twelve months
  • Annual certificate prepared and filed
  • The EIN application
  • The state fee is passed through at cost

Marks in its favor

  • No extra charge for the EIN application
  • The same $199 every year
  • $199 yearly, everything in one

Where it loses points

  • Renews $100 higher than Oklahoma Registered Agent.co

2. Oklahoma Registered Agent.co: best for an inexpensive Oklahoma start

$199 plus fees, $99 yearly after

Oklahoma Registered Agent.co lands in second place, and the reason is clear: it forms the Oklahoma LLC for $199 and covers the agent for year one, after which the agent renews at $99.

The annual certificate is not covered by its price.

What the price covers

  • Your Oklahoma formation is prepared and filed
  • The first year of agent service

  • $199 above the state fee

  • It charges $99 for the EIN step

3. OK Registered Agent.org: best for founders who prepare their own reports

OK Registered Agent.org lands in third place, and the reason is clear: it forms the Oklahoma LLC for $199 and covers the agent for year one, after which the agent renews at $99.

The annual certificate is not covered by its price.

The steps

  1. Step
    1

    Come up with a name

    Type the name into the business search at the Oklahoma Secretary of State before you file anything, so you do not pick one that is in use.

    Jot down two backup names before you search.

  2. Step
    2

    Find your registered agent

    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.

    Any service in our graded list can be your registered agent.

  3. Step
    3

    Will you file it yourself or use a service?

    You can file on your own and pay the state $100, or let a service do it for $199 more; the grades are above.

  4. Step
    4

    Fill out and file the Articles of Organization

    The Articles of Organization (Form 0073) is what you prepare for the Oklahoma Secretary of State, and the filing fee that goes with it is $100.

    Where this comes from: The official page is sos.ok.gov, last confirmed in October 2026

  5. Step
    5

    Get your EIN from the IRS

    With the Oklahoma approval in hand, ask the IRS for an EIN so the LLC can open accounts in its own name. Mainstay Filing treats the EIN application as part of the package.

  6. Step
    6

    Put your operating agreement on paper

    An operating agreement spells out who owns the Oklahoma LLC and how decisions are made. You keep it with your records, and the state never sees it.

  7. Step
    7

    Keep up with Oklahoma's recurring filing

    Once a year the LLC files the annual certificate and pays $25; the due date is anniversary date of the filing of the Articles of Organization.

Behind the ranking

Homework the price handles carries 33% of the report card, and that is where pulled ahead in Oklahoma.

The annual certificate step tipped the grade toward the bundle.

Test yourself on Oklahoma

How much does Oklahoma charge to form an LLC?

$100 goes to the state. Our picks charge $199 on top.

Which form creates the LLC?

Look for the Articles of Organization (Form 0073); the Oklahoma Secretary of State is where it gets filed.

Is a registered agent required?

Every LLC must name a registered agent with an in-state street address.

What does Oklahoma require each year?

Expect to file the annual certificate every year, paying $25 by the deadline: anniversary date of the filing of the Articles of Organization.

Can I form the LLC without a service?

Yes, you may. Pay the state $100 when you file, and remember that the LLC still needs a registered agent.

Which LLC service should a first-time founder use?

By grade: Mainstay Filing, Oklahoma Registered Agent.co and OK Registered Agent.org. Mainstay Filing is first because three chores, the filing, the registered agent and the annual certificate, are folded into a single $199 annual price.
