Foreign Registration: three-year cost with 2026 prices
Service prices come from each company's own pages, read November 12, 2026. State services price only their own state, and each one adds the state's filing fee at cost.
How we picked the order
Three-year price and what the price covers count for 28% apiece, and renewal terms, fit for the state and price clarity divide the other 44%. On a national list, reach decides it: only one provider here serves every state at a single price. MA Registered Agent.org (Massachusetts) and PA Registered Agent.org (Pennsylvania) cost less over three years in their home states, which puts them second and third for companies there.
Agents and multiple states
Registered agents are a state-by-state matter: every state where a company is formed or registered needs an agent on file of its own. Minnesota, New York, Pennsylvania and West Virginia handle the requirement another way, so see their state pages. A national provider puts every renewal in one account. A state specialist may cost less, though only in its home state.
Pick your state
The state pages set Mainstay Filing against that state's own agents, using the state's fees, forms and deadlines. Go to the state list.
