Updated August 10, 2026. Quick answer. Forming an LLC in Idaho costs $100 online; $120 by paper ($100 + $20 manual-processing surcharge) to file, and an ongoing report requirement ($0 — no fee). Five-year total: At least $100 over five years — one or more components (commonly the franchise/minimum tax) is unverified, so treat this as a floor, not a total.
The same question in other states: How Much Does an LLC Cost in Maryland?, How Much Does an LLC Cost in Massachusetts? and How Much Does an LLC Cost in Minnesota?
What it actually costs
| Item | Amount |
|---|---|
| Formation filing fee | $100 online; $120 by paper ($100 + $20 manual-processing surcharge) |
| Annual/biennial report | $0 — no fee |
| Franchise / minimum tax | none found in the sources searched |
| Publication requirement | No newspaper publication requirement was found. |
Five-year cost of ownership: At least $100 over five years — one or more components (commonly the franchise/minimum tax) is unverified, so treat this as a floor, not a total. Publication cost is excluded from this figure — it’s county-driven where it applies, not state-driven, so a single number would be wrong for most filers.
Expedited filing: +$40 expedited (8 working hours); +$100 same-day
The trap worth knowing before you file
The HTML section page renders the fee list without its dollar column (the amounts sit in a leader-dot column that is dropped from the markup); the amounts quoted here were read from the legislature’s own chapter PDF, https://legislature.idaho.gov/wp-content/uploads/statutesrules/idstat/Title30/T30CH21.pdf , with its text extracted. Agency confirmation: https://sos.idaho.gov/business-forms/ and the Certificate of Organization form https://archive.sos.idaho.gov/CORP/forms/LLC/LLC%20Cert%20Org.pdf (Rev. 04/2026). sosbiz.idaho.gov/help/fees serves a 1.5 KB empty app shell and was not usable.

Once the LLC exists, an operating agreement is what actually runs it

If the LLC already exists somewhere else
Everything above prices forming a new Idaho LLC. A company that already exists in another state does not have to be dissolved and re-formed: Idaho takes it in as the same legal entity by the route its own code captions domestication, Idaho Code § 30-22-501(b), and the entity-law filing fee for it is $30 — a separate filing from the formation costs above. Going the other way, an Idaho LLC may leave for another US state under Idaho Code § 30-22-501(a). Either way the move needs both ends to allow it — the state being left as well as the state being joined — which is where most published advice goes wrong.

What letting it lapse costs in Idaho. The catch-up bill is only half the story — in Idaho the LLC Act carries no reinstatement rules of its own; the shared business-entity code it points to allows a genuinely generous ten years. The figures, and the statute they come from, are on reinstating an Idaho LLC.

Closing an LLC in Idaho and forming a new one elsewhere is not the only route out, and it is rarely the cheapest: moving an LLC out of Idaho covers whether Idaho’s statute permits the move and what the Idaho-side filing costs.

Electing S-corp status for this LLC changes the tax picture too. Idaho charges every S-corp a mandatory $20 minimum tax a partnership-taxed LLC never owes. See what Idaho charges at the entity level.
