Oklahoma registered agent prices, 2026: year one, renewal and three-year outlay

ProviderYear 1Year 2Year 3Three-year outlayRenewal at the same price
Mainstay Filing$149$149$149$447Yes

All prices were taken from the companies' own websites on November 12, 2026. Oklahoma's own fees are the same whichever agent is named.

Why the order falls this way

Of the grade, 32% rests on three-year bill and 32% on what the money buys; renewal handling, local rules match and pricing openness share the remaining 36%. What the money buys decided Oklahoma.

Mainstay's agent plan grades higher on coverage: served papers are scanned the same business day at no fee, the price is identical in all fifty states and three government mailings a year are scanned free. Oklahoma Registered Agent.co wins on cost, and the margin is thin.

Every criterion and weight is listed on How we rank.
