Short Q&A
What about the state where I formed the LLC?
Each state applies its own rule, so your home state still needs an agent. A provider active in every state, such as Mainstay Filing, covers both.
What does each charge over three years?
$497 for Mainstay Filing, $397 for OK Registered Agent.org, $397 for Oklahoma Registered Agent.co (services only).
What are your sources?
We link each state fee to its official page and take service prices from the company sites, dated.
Can I skip hiring one?
No. What you pay a service covers the labor and the agent role, not anything the state demands.
Will a service do the registration for me?
Yes. Each pick prepares and files it, and the state fee does not depend on which you choose.
Which one do you pick in Oklahoma?
Mainstay Filing first: $199 on top of the state fee gets you registered, with the registered agent free in year one and $149 a year afterward. OK Registered Agent.org and Oklahoma Registered Agent.co follow.
