1. ID Registered Agent.org: best for an Idaho LLC that plans to stay local

Formation $199, then $99 a year for the agent, plus the state fee

9.3Editorial score
out of 10

ID Registered Agent.org wins here: Idaho formation at $199 over the state's fee, year-one registered agent service included and $99 a year to keep the agent.

The plan gives the company an in-state street address as its registered office, and papers served on the company are scanned to your online account.

The annual report filing is not in its published prices, so you file it with Idaho yourself every year.

Over three years it comes in under Mainstay Filing, and cost is one of our two heaviest criteria.

What you get

  • The formation filing
  • A first year of registered agent service

What we like

  • A $199 service fee plus the filing fee
  • Year-one registered agent service included

2. Mainstay Filing: best for formation, agent and annual report for one price

$199 each year plus the state fee

9.1Editorial score
out of 10

Second place goes to Mainstay Filing: the Idaho formation, your registered agent and the annual report all sit in a single $199 yearly charge.

Mainstay files the annual report for you as part of the renewal. Idaho charges no state fee for it, due last day of the entity's anniversary month; the state's fee is passed through at cost.

Over three years ID Registered Agent.org is $200 cheaper, which puts Mainstay Filing behind it on cost.

What you get

  • Formation paperwork prepared and filed
  • A full year of registered agent service
  • The annual report, prepared and filed
  • The EIN application

What we like

  • One $199 yearly price that includes the annual report
  • Idaho's fee is passed through at cost
  • $199 at renewal, nothing extra
  • The EIN application comes with it

Cons

  • From year two its agent costs $100 a year more than ID Registered Agent.org's

Prices were read from each company's own pages on November 12, 2026. Idaho's $100 filing fee goes on top of every row and is not counted in these totals.

Why this order

Two criteria lead Filing Verdict's method at 35% apiece: total over three years and paperwork the price handles. Renewal behavior, match to the state and up-front pricing share the other 30%, and Idaho came down to total over three years.

ID Registered Agent.org totals $397 over three years, $200 under Mainstay Filing. Mainstay would also file the annual report, but an owner can file it alone at no cost, so the lower price carried this page.
