The services we pick in Montana
Criteria in order of weight: three-year fees, coverage, renewal terms, fit with Montana, clear state fee (method).
1. Registered Agent MT.org: best for a single added state
$199 plus $70 to the state, then $99 yearly
We put Registered Agent MT.org at number one since $199 plus state fees for the registration, with the agent covered in year 1.
Mainstay Filing costs more over three years, and that criterion is worth 34% of the score.
What the price takes in
- Prepares and submits the registration
- A year of agent service
In its favor
- The agent renews at $99
- The first agent year is free
- $199 and the state fee
Against it

2. Mainstay Filing: best for registering in many states
$199 plus $70 to the state, then $149 yearly
Mainstay Filing comes second because the provider fee is $199 in any state, and the first year of agent service costs nothing.
That $100 difference from Registered Agent MT.org over three years is what keeps it out of first place.
The free year is followed by $149 a year, in every state.

- Registered agent costs nothing in the first year
- Works in all fifty states
In its favor

$199 plus $70 to the state, then $99 yearly
We put Montana Registered Agent.co third since $199 plus state fees for the registration, with the agent covered in year 1.
Its prices equal Registered Agent MT.org's, so the two are close.
