Once registered
No fee, annual report
Our pick
Idaho Registered Agent.co, ID Registered Agent.org then Mainstay Filing
Our Idaho answer, best first
The order follows our five questions: three-year cost first, then how much the price covers.
1Ask this one first
1. Idaho Registered Agent.co: best for adding only this state
$199 plus the state fee, then $99 a year
Idaho Registered Agent.co comes first: three years of its service fees come to $397.
Where the three-year total is smaller, cost carries the day, and here it is smaller than at Mainstay Filing.
How was the bottom line figured? Add the filing fee, the next two reports and the minimum tax if the state has one. Anything with no fixed price, a newspaper notice for instance, is described above and kept out of the sum.
Questions people also ask
Do I still need an agent in my home state?
Probably. Your home state still wants an agent of its own. A company that operates in every state, Mainstay Filing for example, can hold both roles, whereas a local firm covers a single state.
What do the picks cost over three years?
Idaho Registered Agent.co comes to $397; ID Registered Agent.org comes to $397; Mainstay Filing comes to $497 for the services alone.
Where do these numbers come from?
Official Idaho sources back the state side, and posted company prices back the service side.
Does the law require a service?
No. What the law asks for is a filing, and it does not say who has to send it.
Will a service file the registration for me?
They do. All the picks prepare and send the registration, so the only thing that changes with your choice is the service fee.
Who should I ask first about a foreign registration service in Idaho?
Idaho Registered Agent.co, because registering costs $199 over the state fee, with the agent covered in year one, then $99 a year. After that, ID Registered Agent.org and Mainstay Filing.
