When Idaho actually bills you

Idaho's recurring filing is due By the last day of the anniversary month of formation each year — put it in a calendar the day you form, because the state will not chase you before it penalises you.

Point in time What Idaho charges Amount Running total
At formationArticles / Certificate of Formation$100$100
Year 1 cycleAnnual Report (no charge in this model)$0$100
Year 2 cycleAnnual Report (no charge in this model)$0$100
Year 3 cycleAnnual Report (no charge in this model)$0$100

Idaho carries no modelled recurring SOS charge under the stated scenario, so the running total flattens after formation — but a required zero-fee filing can still exist, and missing it can still cost you standing.

How Idaho ranks against the other 50 charters

Across the 51 jurisdictions covered on this site, Idaho sits at #8 — the 8th cheapest three-year state charter — at $100 in Secretary of State and revenue-department dollars. That is $65 more than Montana, the cheapest charter in the ranking ($35), $180 below the $280 median, and $2,410 less than California at $2,510. In plain terms, Idaho lands in the cheaper half of the table.

Ranking basis for Idaho: Formation $100 (online) + 3× online annual report $0 = $100.

Ranking caveat for Idaho: Whether SOSBiz card convenience fee applies to $100 formation (some guides cite ~$1–$3).

Registered agent (Idaho)

  • Registered agent with Idaho street address required.

Put the agent next to the state's own bill: three years of Idaho state fees is $100, while the cheapest provider path in our national 3-year comparison runs $289 (Formation $39 (RA Y1 included)) and the most expensive runs $747 (Basic $0 + RA $249/yr) — a $458 spread for the same statutory job. On the cheapest path the service, not Idaho, is about 74% of your three-year outlay. Choosing the agent well is usually a bigger lever than choosing the state.

Gotchas (fact-based)

  • Zero-fee annual report still required; non-filing can lead to administrative dissolution after ~60 days past due.
  • Credit-card convenience fees on SOSBiz (if any) not included.

Who Idaho is for / not for

Often a fit when…

  • Domestic LLCs seeking low ongoing SOS cost after a modest formation fee.

Often a poor fit when…

  • Filers who cannot use SOSBiz online (paper path adds manual fees).

Common questions about Idaho LLC cost

How much does it cost to form an LLC in Idaho?

$100 to Idaho Secretary of State for the formation filing. Certificate of Organization base $100 online via SOSBiz; paper adds $20 manual processing ($120). That is the state charge only. A formation service is a separate bill on top: Formation $39 (RA Y1 included) works out to $39 in year one, versus $249 on the most expensive path we track.

What are the ongoing Idaho LLC fees after year one?

$0 in recurring Annual Report charges under the modelled scenario (By the last day of the anniversary month of formation each year). No SOS filing fee for online annual report; paper may incur $20 manual processing. Filing is still mandatory. Recurring state charges are what make a low formation fee misleading — they are the reason this site models three years instead of one.

What does a Idaho LLC really cost over three years?

$100 in Idaho state fees, plus whatever your provider charges. With the cheapest tracked path that is $389 all-in over three years; with the most expensive it is $847 — a $458 difference that has nothing to do with Idaho.

Do I need a registered agent in Idaho?

Yes. Registered agent with Idaho street address required. Confirm Idaho's DIY-versus-commercial agent rules with Idaho Secretary of State before you file — a home address here becomes public record. On the money side, the four providers tracked here charge $0–$249 in year one for formation plus the agent, then $125–$249 a year in agent renewal after that — separate from every Idaho figure above.

Is Idaho a cheap state to form an LLC?

On charter cost alone, Idaho ranks #8 of 51 at $100 over three years, against a $35 floor and a $2,510 ceiling. But cheapest charter is not the same as cheapest outcome: if you operate somewhere else you will likely foreign-qualify there and pay that state's fees and taxes too. See the full 3-year state fee ranking for the comparison.

How the Idaho three-year number is built

Formation $100 (online) + 3× online annual report $0 = $100. Figures are re-derived from the cited Idaho sources rather than copied from other guides.

Deliberately excluded from the Idaho state subtotal:

Same exclusions are applied to every state so the ranking stays apples-to-apples.
