More questions

Do I need an agent in each state?

Both states apply their own rules, so your home state still wants an agent. A company that works in every state, like Mainstay Filing, can cover the pair.

What's the three-year total for each?

OH Registered Agent.org: $397 / Mainstay Filing: $497 (services only).

What do the numbers rest on?

What the state charges comes from official Ohio publications; what services charge comes from what they publish.

Does the state make me use a service?

Not required. What you'd pay a service is for convenience.

Is filing included in what they sell?

Yes. Every pick prepares and files it, and the state fee is the same no matter who you pick.

Who would you go with in Ohio?

OH Registered Agent.org wins on cost across three years, ahead of Mainstay Filing.
