Formation in sequence

  1. Section 1

    Settle on the legal name

    The records at the Oklahoma Secretary of State show every name in use. Look yours up before preparing any forms, because Oklahoma can refuse a duplicate.

    Keep a second choice on hand.

  2. Section 2

    Designate the 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.

    Providing the registered agent is part of what each recommended service sells.

  3. Section 3

    Who prepares the filing

    Without a service the charge is the state's $100. With a recommended service it grows by $199.

  4. Section 4

    The state wants the Articles of Organization

    To form the company, deliver the Articles of Organization (Form 0073) to the Oklahoma Secretary of State together with $100.

    Reference: Reference: sos.ok.gov, consulted October 2026

  5. Section 5

    Request an Employer Identification Number from the IRS

    The IRS, not Oklahoma, issues EINs. Apply after the state approves the LLC and give the number to your bank. With Mainstay Filing this section is completed for you.

  6. Section 6

    Write the operating agreement

    Definition: the operating agreement sets out shares, voting and what happens when a member leaves. It is private.

  7. Section 7

    Keep the LLC in good standing

    Good standing depends on the annual certificate, which is filed every year and costs $25, with a deadline of anniversary date of the filing of the Articles of Organization.
