Naming an Oklahoma registered agent, assignment by assignment

  1. Assignment

    Textbook page: Check the textbook page: sos.ok.gov (read October 2026)

  2. Assignment
    2

  3. Assignment
    3

    Pick an address that complies

    If you pass the tests above, you can name yourself; hiring one of the graded agents costs $99 to $149 a year.

  5. Assignment
    5

    Name the agent in your filing

    The Articles of Organization (Form 0073) asks for the agent's name and address, and the Oklahoma Secretary of State also takes change filings from LLCs that switch agents.

  6. Assignment

    Watch the details

    Oklahoma keeps your agent's details current through the annual certificate ($25, every year, due anniversary date of the filing of the Articles of Organization); notices about it land with the registered agent.

The bill

EntryPaid toCost
Agent serviceThe service company$99 to $149 a year
RenewalThe service company$99 to $149 a year
Annual certificateState agency$25 every year
Rows for the state use Oklahoma's published fee schedules (see the textbook pages beneath the table), and each service row uses that company's own price. Over three years the state row adds the filing, the year-two report, the year-three report and any minimum tax.

Why the list runs this way

Tuition across three years settled first place in Oklahoma. It is worth 30% of the grade, and the rest comes from homework the price does, year-two tuition, fit with the state class and fees a student can read.

Count three years and OK Registered Agent.org totals $297, $150 below Mainstay Filing.
