The desk picks Mainstay Filing: the formation, the registered agent and the annual certificate all ride on one $199 yearly price, renewing at $199.

Mainstay Filing $199 $199 $199 $597 Yes

Every price here was read off the company's own pages on November 12, 2026. Oklahoma's $100 filing fee comes on top of every row and is left out of these totals.

What tipped the order

Here is the weighting: 33% for spend over three years, 33% for work the price removes, 34% spread over what renewal looks like, fit with the state and plain price display. In Oklahoma, work the price removes made the call.

Oklahoma wants a report each year and charges $25. Mainstay's price covers that filing and Oklahoma Registered Agent.co's does not, and that outweighed Oklahoma Registered Agent.co's lower three-year cost.
