Every official charge for forming an LLC in Idaho in 2026: the filing fee, the other mandatory state costs, the documents you need, and the filing office's own contact details — taken from the state's published sources, not from a filing service.
| Charge | Amount |
|---|---|
| Filing fee — Certificate of Organization | $100 |
| First-year minimum total | $100 |
The total is the cheapest filing channel plus the fixed mandatory charges that fall due in year one. Variable charges are listed at “No fixed fee” and are not folded into the total.

| Paper / by mail filing | $120 |
Secretary of State Business Forms page lists the Certificate of Organization - Limited Liability Company at a $100 base filing fee plus a $20 manual processing fee for paper submissions ($120 total on paper); online filing through SOSBiz avoids the manual fee. The $20 paper surcharge is Idaho Code 30-21-214(f) (forms not generated by the electronic filing system that require manual data entry). Optional expedited service is $40 for evidence of filing within 8 working hours or $100 for same-day service on filings submitted before 1:00 p.m. Mountain Time (Idaho Code 30-21-214(d)-(e)).
Certificate of Organization: Filed with the Idaho Secretary of State, online through SOSBiz or on paper. Contents are set by Idaho Code 30-25-201.
File through the official portal above — third-party filing services charge extra for the same filing.
Idaho requires a annual report — fee No fee.
Each year before the end of the month during which the LLC's public organic record (Certificate of Organization) became effective; beginning one year after formation, the report must be received by the Secretary of State not later than the close of business on the final day of that anniversary month (Idaho Code 30-21-213(c)).
Idaho Code 30-21-214(b)(7) lists the annual report fee as 'No fee' (filed online through SOSBiz). Paper annual report forms are available by request only, and paper submissions carry the $20 manual processing fee described on the Secretary of State Business Forms page.
Once the LLC is formed, these pages work out what it keeps: Idaho Tax Brackets · Idaho Income Tax Calculator · Idaho Paycheck Calculator.
Idaho's first-year minimum of $100 sits in the full ranking of all 51 jurisdictions — the cheapest first year is Montana at $35 and the most expensive is California at $870.

Every official charge for forming and keeping an LLC in Idaho in 2026: a $100 filing fee for the Certificate of Organization, a first-year minimum of $100, the documents the state asks for, and the filing office's own phone, website and portal — read from the state's published sources, not a filing service's price list.
Forming an LLC in Idaho: you pay $100 to file the Certificate of Organization with the Idaho Secretary of State. With the mandatory year-one charges counted, your first-year minimum is $100; after that the recurring state cost is No-fee annual report.
Every figure comes from the state's own published fee schedule or statute (the page lists its official sources) and was checked on 3 November 2026. The first-year minimum is the cheapest filing channel plus the fixed mandatory charges that fall due in year one; annual report fees fall due after year one, and variable charges such as newspaper publication have no fixed amount, so both are shown separately rather than folded into the total.
Filing the Certificate of Organization costs $100 at the cheapest channel. Counting the mandatory state charges that fall due in year one, the first-year minimum is $100. Registered-agent services and local licences are extra and are not state charges.
Idaho requires a annual report costing nothing — there is no fee. Each year before the end of the month during which the LLC's public organic record (Certificate of Organization) became effective; beginning one year after formation, the report must be received by the Secretary of State not later than the close of business on the final day of that anniversary month (Idaho Code 30-21-213(c)).
Certificate of Organization; Registered agent in Idaho; Operating agreement. You will also need a free EIN from the IRS — a federal step that is the same in every state.
You file with the Idaho Secretary of State, Business Services Division. Phone: (208) 334-2301. No email address is published — the office takes enquiries through the contact form on its website. File online at https://sosbiz.idaho.gov.
No — beyond the Certificate of Organization filing fee and the annual report, Idaho records no other mandatory state charges for a standard LLC.
