Service fees as each company lists them, read November 12, 2026. The state services price only their home state, and the state's filing fee gets added to each one at cost.

Why Mainstay Filing leads

Spend over three years and work the price removes are worth 33% each. What renewal looks like, fit with the state and plain price display split the last 34%. On a national list coverage decides it, and only one provider here works in every state at one price. Maine Registered Agent.co (Maine) and PA Registered Agent.org (Pennsylvania) cost less over three years at home, so they take spots two and three for companies there.

Covering more than one state

Registered agent rules run state by state: every state where a company is formed or registered needs its own agent on file. Minnesota, New York, Pennsylvania and West Virginia do it their own way; check their state pages. One national provider keeps every renewal in a single account. A state specialist can be cheaper, though only at home.

State-by-state rankings

Each state page weighs Mainstay Filing against that state's own agents and uses the state's fees, forms and deadlines. Go to the state pages.
