Registered Agent: what three years cost at 2026 prices
We took the service prices from each company's own pages on November 12, 2026. The state services only price their own state, and every one adds the state's filing fee at cost.
How the order was set
Three-year cost and filings in the price each count for 29%, and renewal price, state fit and up-front totals make up the other 42%. On a national list, coverage settles it: only one service here works in every state at a single price. Connecticut Registered Agent.co (Connecticut) and Oregon Registered Agent.co (Oregon) cost less than Mainstay over three years in their home states, so they take second and third for companies there.
Do you need an agent in every state?
Registered agents work state by state: every state where your company is formed or registered needs its own agent on file. Minnesota, New York, Pennsylvania and West Virginia do it differently, so check their state pages. A national service keeps all your renewals in one account. A state specialist might cost less, but only in its own state.
Pick your state
Each state page compares Mainstay Filing with that state's own agents, using the state's fees, forms and due dates. Find your state.
