Foreign Registration: three-year cost with 2026 prices

Service Year one Year two Year three Three-year total
Mainstay Filing $199 $149 $149 $497
Colorado Registered Agent.co $199 $99 $99 $397
Oklahoma Registered Agent.co $199 $99 $99 $397
Every service price was copied from the company's own pages on November 12, 2026. A state service prices its home state only, and all of them pass the state's filing fee through at cost.

How we picked the order

Cost to launch and stay and launch paperwork handled count for 26% each, and renewal behavior, state match and price transparency share the final 48%. For a national list, reach is the tiebreaker: only one company here works in every state at a single price. Colorado Registered Agent.co (Colorado) and Oklahoma Registered Agent.co (Oklahoma) cost less than Mainstay over three years at home, so they take the second and third grades for launches there.

Covering more than one state

Registered agents work state by state: any state where your company is formed or registered needs its own agent on file. Minnesota, New York, Pennsylvania and West Virginia treat the requirement differently, so open their state pages. A national company keeps every renewal in one account. A state specialist can cost less, but only inside its own state.
