Who should you ask in Oklahoma?
The order follows our five questions: three-year cost first, then how much the price covers.
1Our first answer
1. Oklahoma Registered Agent.co: best for companies that stay local
$199 plus the state fee, then $99 a year
Oklahoma Registered Agent.co is the one to ask first in Oklahoma because $199 gets the LLC formed, and the agent renews each year at $99.
Put the totals side by side and this one is lower than Mainstay Filing; cost has the heaviest weight in our scoring.
2. Mainstay Filing: best for one price for setup and upkeep
$199 a year plus $100 for the state
Why Mainstay Filing in second place? One yearly price of $199 pays for forming the LLC, serving as the registered agent and filing the annual certificate, then renews at $199.
The $200 difference from Oklahoma Registered Agent.co over three years accounts for the lower place.
Because the annual certificate is inside the service, the only extra is Oklahoma's own $25, billed at cost.
The annual certificate repeats every year, at $25 each time. Due date, as the state puts it: anniversary date of the filing of the Articles of Organization.
Every line above points to the state's own page. The total under them is ours, and it covers the filing, two reports and any minimum tax, nothing that varies by newspaper or county.
Still wondering?
Who applies for the EIN?
Mainstay Filing includes the EIN application. The others charge extra: Oklahoma Registered Agent.co $99; OK Registered Agent.org $99.
How do the three-year totals compare?
Oklahoma Registered Agent.co comes to $397; Mainstay Filing comes to $597; OK Registered Agent.org comes to $397, with state fees on top.
Are the fees official?
State fees come from Oklahoma's official documents, and service fees come from each company's own pricing page. Both carry dates on this page.
Does the law require a service?
Not at all. The state takes filings from owners directly. A service just saves you time, and it can double as your agent.
Are there yearly state fees?
The annual certificate repeats every year, at $25 each time. Due date, as the state puts it: anniversary date of the filing of the Articles of Organization.
What is the best LLC service for Oklahoma?
Oklahoma Registered Agent.co, because it opens at $199 with the first agent year included and renews at $99. After that, Mainstay Filing and OK Registered Agent.org.
