Idaho LLC Cost (2026): $100 Once, Then a Free Annual Report
Idaho charges once and then asks only for paperwork. Formation costs $100 online, and the annual report has no fee at all. That makes an Idaho LLC one of the cheapest in the country to keep in good standing, provided you actually file the free report every year.
The $100 Certificate of Organization
An Idaho LLC is formed by filing a Certificate of Organization with the Idaho Secretary of State. Filing online through the SOSBiz portal costs $100. Paper filings cost $120, because the state adds a $20 manual processing fee, and paper submissions without that fee are rejected.
The certificate lists the LLC name, the registered agent with a physical Idaho address (not a P.O. box), a mailing address, and at least one member, manager, or organizer.
Northwest Registered Agent
Idaho’s public records show your registered agent address. $39 formation + $100 state fee, free registered agent for year one, then $125/yr.

Form Your LLC with Northwest ($39) →Lowest 3-year cost we found: Northwest $289 vs Bizee $298 vs ZenBusiness $497 (service fees; state fees extra). Northwest also puts its address on your public filings instead of yours where the state allows.
The Free Annual Report
Every Idaho LLC files an annual report each year by the last day of the month in which it was formed. An LLC formed in August 2026 files by August 31, 2027, and every August after. The report confirms the registered agent, addresses, and governing persons.
There is no filing fee. Idaho is one of very few states where a domestic LLC’s yearly state filing costs nothing.
Free Does Not Mean Optional
Because no invoice arrives, the annual report is easy to forget. If it is not filed within 60 days after the due date, the Secretary of State may administratively dissolve the LLC. A dissolved LLC loses good standing and must be reinstated before it can reliably sign contracts, open accounts, or rely on its liability protection.
Put the anniversary month in your calendar the day you form, or use a registered agent that sends reminders.
Where the Real Recurring Cost Is
With no annual state fee, the only regular expense for many Idaho LLCs is a registered agent, and only if you pay for one. You can serve as your own agent if you have an Idaho street address and are available during business hours. Out-of-state owners, or owners who do not want their home address on the public record, typically use a commercial agent.
Idaho does not impose a franchise tax on LLCs. Profits pass through to the owners’ Idaho income tax returns by default.
