The reasoning behind the list
Cost over years one to three and inclusions per price are weighted 27% each. Renewal price and terms, fit with state rules and price clarity fill the last 46%. On a nationwide list coverage settles the order, and just one provider here works in every state at one amount. Massachusetts Registered Agent.co (Massachusetts) and OK Registered Agent.org (Oklahoma) sum to less over three years at home, which gives them places two and three for companies in those states.
Registered agents across states
Registered agents are required state by state: each state where a company is formed or registered needs its own agent on record. Minnesota, New York, Pennsylvania and West Virginia do this differently; see their state pages. One national provider keeps every renewal on a single account. A state specialist may be cheaper, but only in its own state.
Find your state
Each state page sets Mainstay Filing against that state's own agents, using the state's fees, forms and deadlines. Browse the state ratings.
