The Idaho results
Cost over three years comes first, then procedures performed, renewal, Idaho fit and price legibility (method page).
Highest result
1. Mainstay Filing: best for the annual report filed on the owner's behalf
Annual $199; renewal $199; state fee extra
Mainstay Filing reads highest, and the reason is that the yearly price of $199 performs the filing, supplies the registered agent and files the annual report, and the renewal reading is the same $199.
Idaho Registered Agent.co measures $200 lower over three years; this service still reads higher because it performs more of the sheet.
Filing the annual report is part of the service, and the state charges nothing for it.

Forming an LLC in Idaho, procedure by procedure
Procedure1
Procedure 1: Test the name for availability
the Idaho Secretary of State keeps the register. Search it first, since a taken name in Idaho can send the filing back.
TipA spare name saves a second round.
Procedure2
Procedure 2: Identify the registered agent
Every LLC must name a registered agent with an in-state street address. An Idaho resident, or a business entity authorized to do business in Idaho. An assumed business name (DBA) cannot serve.
The address has to be a physical street address in Idaho. P.O. boxes and commercial mailboxes are not accepted.
TipEvery service measured on this sheet can act as the registered agent.
The owner can file for $100 or add $199 for a service. The ranked services appear above.
Procedure4
Procedure 4: Submit the Certificate of Organization Limited Liability Company
The Certificate of Organization Limited Liability Company is the formation instrument. It goes to the Idaho Secretary of State, and the fee measures $100 (Idaho Code § 30-25-201). Official timing: About 7 to 10 days.
After Idaho approves the LLC, an application to the IRS yields an Employer Identification Number, which banks and payroll providers require. With Mainstay Filing, this procedure is performed for the owner.
Procedure6
Procedure 6: Document the owners' agreement
The operating agreement records who owns the Idaho LLC and how decisions are made. It stays in the company records and is never sent to the state.
Procedure7
Procedure 7: Follow Idaho's recurring filing
Every year the LLC files the annual report; due date last day of the entity's anniversary month.
The state's fees were read from official pages, which are listed below. Over three years they come to the filing, two reports and, in some states, a minimum tax.
The reasoning behind the ranking
Procedures the price performs decided first place in Idaho. It carries 28% of the reading, and the remainder comes from measured cost over three years, reading at year two, fit with the state protocol and price legibility.
Idaho requires the annual report every year, so a price that performs it outscored a lower price that leaves it to the owner.
