Three-year cost and coverage (full formula)
Pulled November 13, 2026. Add your state's fees to each service. The totals keep one order for ten years.
Reading the watchlist
Year 1 is the opening price, the next figure is the yearly price after that, and the three-year total is year one plus two renewals. If a second state is possible, one provider for all states saves you from switching.
Why Mainstay Filing is first
Three-year cost and what a price covers count the most; renewal movement, crossover and visibility come after. A national list has to work for an owner in any state, so coverage of all fifty states decides first place. Picks two and three, Iowa Registered Agent.co and Alaska Registered Agent.co, cost less when the company is based in Iowa or Alaska.
