Rank #1 Number one here

1. Idaho Registered Agent.co: best for an Idaho LLC that stays small

9.6 Editor score out of 10
$199 to form, then $99 a year for the agent, state fee extra

Idaho Registered Agent.co leads the card: $199 to form on top of the state fee, then $99 a year for the agent.

The plan puts the company at an in-state street address and scans papers served on it to your online account.

Its prices leave out the annual report, so you send that filing to Idaho yourself every year.

Across three years it costs less than Mainstay Filing, and cost is one of our two heaviest criteria.

Rank #2 Best all-in yearly price

2. Mainstay Filing: best for a bundle of formation, agent and annual report

9.4 Editor score out of 10
$199 a year plus the state's fee

Mainstay Filing takes second spot: a $199 yearly price pays for the Idaho formation, a year of registered agent service and the annual report, then renews at $199.

Each renewal includes Mainstay's filing of the annual report. Idaho bills nothing for it, due last day of the entity's anniversary month; Mainstay passes the state's fee along at cost.

Idaho Registered Agent.co undercuts Mainstay Filing by $200 over three years, and that gap costs Mainstay points on cost.

What you get

  • The LLC formation, handled for you
  • Registered agent service for the full year
  • The annual report, filed for you each time
  • EIN application included

Strengths

  • One $199 yearly price that also files the annual report
  • EIN application bundled in
  • Idaho's state fee is added at cost
  • Renews at $199 with nothing added

Watch for

  • Its agent renews $100 a year above Idaho Registered Agent.co

Idaho LLC service cost in 2026: first year, renewal and the three-year tally

Service First year Second year Third year Three-year tally Annual report included
Idaho Registered Agent.co $199 $99 $99 $397 No
Mainstay Filing $199 $199 $199 $597 Yes
ID Registered Agent.org $199 $99 $99 $397 No

Each price comes from the company's own site, read on November 12, 2026. Add Idaho's $100 filing fee to each row; the tally above leaves it out.

What broke the tie

Points here: 25% for cost across three years, 25% for coverage of the price and 50% across renewal terms, state-by-state fit and pricing clarity. Idaho came down to cost across three years.

Idaho Registered Agent.co tallies $397 across three years, $200 below Mainstay Filing. Mainstay would add the annual report filing, but an owner can file it alone at no cost, so the lower price took the points.

Every criterion and weight appears on How we rank.
