Idaho foreign registration service charges in 2026: year one, renewals and the three-year total
| Provider | Year one | Year two | Year three | Total over three years | Agent covered in year one |
|---|
| ID Registered Agent.org | $199 | $99 | $99 | $397 | Included |
|---|
| Mainstay Filing | $199 | $149 | $149 | $497 | Free |
|---|
| Idaho Registered Agent.co | $199 | $99 | $99 | $397 | Included |

Each charge was taken from the provider's own pages on November 12, 2026. Idaho's $100 registration fee is payable in addition to every row below and is not in the totals.
The reasoning for the order
The Startup Judge weighs charge over three years at 31% and work taken off the founder at 31%; renewal conduct, fit with local rules and pricing in plain sight divide the remaining 38%. In Idaho, charge over three years was the criterion that tipped it.
Over three years ID Registered Agent.org totals $397, $100 less than Mainstay Filing. Both providers include the first year, so the renewal charge carried the ruling.
