Class favorites in Oklahoma

Five weighted criteria set the order (see how we grade), and three-year tuition and homework done count most.
Start with this one

1. Mainstay Filing: best for no annual certificate paperwork to do

$199 per year

The class favorite is Mainstay Filing, because for one yearly fee of $199 the class assignments on filing, registered agent and annual certificate are all done for you.

OK Registered Agent.org is $200 cheaper over three years; this one still earns the higher grade because it does more of the work.

The annual certificate is part of its homework, and Oklahoma's $25 fee is billed to you at cost.

Covered by the tuition

  • Formation filing prepared and sent
  • Registered agent for the whole year
  • Annual certificate filed on time
  • EIN application included
  • No markup on the state fee

Strengths

  • The EIN application is in the price
  • $199 every year
  • One yearly fee of $199, annual certificate included

Weak spots

  • $100 a year more than OK Registered Agent.org at renewal
In-state service

2. OK Registered Agent.org: best for a thrifty Oklahoma start

$199 plus the state fee, then $99 a year

Second place goes to OK Registered Agent.org, since the formation costs $199 on top of the state fee, and the agent renewal is $99.

Nothing in the price covers the annual certificate.

Covered by the tuition

  • Formation paperwork handled
  • A year of agent service is part of the price

Strengths

3. Oklahoma Registered Agent.co: best for LLCs that never leave Oklahoma

$199 plus the state fee, then $99 a year

Third place goes to Oklahoma Registered Agent.co, since the formation costs $199 on top of the state fee, and the agent renewal is $99.

Nothing in the price covers the annual certificate.

On price, it is level with OK Registered Agent.org.

The class, assignment by assignment

  1. Assignment
    1

    Check that nobody else has the name

    If a Oklahoma company already holds your name, the filing can be sent back, so look it up at the Oklahoma Secretary of State before going any further.

    Bring a second name with you.

  2. Assignment
    2

    Appoint 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.

    The registered agent role comes with each graded service.

    Self-filing versus a service

  4. Assignment

    Complete, sign and file the Articles of Organization

    Your homework here is the Articles of Organization (Form 0073). It is addressed to the Oklahoma Secretary of State and costs $100.

    Order the LLC's federal tax ID

    The IRS gives out EINs, not Oklahoma. Apply once you are approved, then hand the number to your bank. Mainstay Filing files the EIN application as part of the package.

  6. Assignment
    6

    Draft the operating agreement

    The operating agreement is where the Oklahoma LLC's owners write down who owns what and how decisions get made. The company keeps it; the state never sees it.

  7. Assignment
    7

    Stay in good standing in Oklahoma

    Once a year the LLC sends in the annual certificate with $25; it is due anniversary date of the filing of the Articles of Organization.

Common questions

What will starting a Oklahoma LLC cost?

The state's fee is $100. The graded services bill $199 on top.

Which form creates the LLC?

The Articles of Organization (Form 0073) is what creates the company, and the Oklahoma Secretary of State is who receives it.

Is a registered agent required?

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

What does Oklahoma require each year?

Once a year the LLC sends the state its annual certificate: $25, due anniversary date of the filing of the Articles of Organization.

Can I form the LLC without a service?

Yes. The state takes $100 at filing, and you still need a registered agent on record.

Which LLC service should a first-time founder use?

Mainstay Filing, because you hand in $199 each year and the formation, the registered agent and the annual certificate are taken care of. Behind it come OK Registered Agent.org and Oklahoma Registered Agent.co.
