Starting a Oklahoma LLC, stage by stage

  1. Stage 1

    Pick a name and make sure it is free

    the Oklahoma Secretary of State keeps the list of names in use, so check there before you spend time on forms; Oklahoma may turn down a duplicate.

    Decide on a plan B name in case the first is gone.

  2. Stage 2

    Decide who will act as a 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.

    Our recommended services all work as a registered agent.

  3. Stage 3

    Handle it alone or get help

    Skipping the service saves $199; it also means you fill in every form. Our picks are listed in order.

  4. Stage 4

    The paper to file is the Articles of Organization

    This is the stage that makes the company real. Hand the Articles of Organization (Form 0073) to the Oklahoma Secretary of State and pay $100; you are filing under Oklahoma law.

    Check it yourself: sos.ok.gov, last viewed October 2026

  5. Stage 5

    Order a federal tax ID for the LLC

    EINs come from the IRS, not Oklahoma. Apply after approval and hand the number to your bank. This stage is part of what Mainstay Filing sells.

  6. Stage 6

    Draft the operating agreement

    Ownership and decision rules go in the operating agreement, a document that lives apart from the Oklahoma filing.

  7. Stage 7

    Mark the dates that come back around

    Each year, Oklahoma looks for the annual certificate (anniversary date of the filing of the Articles of Organization) and charges $25.

Costs, stage by stage

StageReceiverCost
The formation stageThe state$100
Annual certificateThe state$25 every year
Optional serviceThe service$199 in year one
Three years of state feesThe state$150
The state rows come from Oklahoma's published fee schedules (the pages we opened are listed under the table), and each service row comes from that company's own price. Across three years the state row counts the filing, the report in year two, the report in year three and any minimum tax.

Why Mainstay Filing is first

What decided it was work taken off your desk, which carries 32% of the score.

Having the annual certificate handled counted for more than OK Registered Agent.org's lower three-year total.
