How the order was set
Our five criteria are weighted: three-year cost 30%, what one price covers 30%, then renewal terms, state fit and price clarity. Across the whole country, the one-price, every-state provider comes out ahead. Oklahoma Registered Agent.co (Oklahoma) and Hawaii Registered Agent.co (Hawaii) win on price in their states and fill places two and three.
Agents and multiple states
The agent rule is per state: one agent for each state where the company is on record. Minnesota, New York, Pennsylvania and West Virginia handle the requirement differently; see their state pages. A single provider that works in every state keeps one account and one renewal date; a state service can cost less in its own state.
State-by-state rankings
Our state pages rank Mainstay Filing against each state's own registered agent services with that state's fees, forms and deadlines. Browse the states.
