Idaho's LLC formation section forms the company on delivery of a certificate of organization and imposes no newspaper publication step. That section belongs to the Idaho Uniform Limited Liability Company Act; a separate chapter covering all business entities supplies the cross-cutting filing and registered agent rules. An earlier note cited that general chapter, which is not the LLC act.

Registered agent is listed separately because it is a commercial service, not a state charge. Commercial registered-agent services, not a state charge.

What does an Idaho LLC cost over five years?

State charges only in the first column; the second adds a registered-agent service at the $125/yr market midpoint.

Period	State cost only	With registered agent
Year 1 (formation + first filing)	$100	$225
Each year after	$0/yr	$125/yr
Five-year total	$100	$725

First filing timing: Idaho law starts the clock one year out: 'Beginning one (1) year after the public organic record of a domestic filing entity became effective ... and each year thereafter, the annual report must be received in the office of the secretary of state not later than the close of business on the final day of the applicable month.' An LLC organized in August 2026 therefore files its first annual report by August 31, 2027.

Is Idaho expensive compared with other states?

Idaho ranks 12th cheapest of 50 states on first-year cost , $132.16 below the $232.16 national average. On ongoing annual cost it ranks 3rd.

Cheaper state	First-year cost	You would save
Montana	$35	$65
Arizona	$50	$50
Missouri	$50	$50

What cost traps are specific to Idaho?

A free annual report can still cost you the LLC

Idaho charges $0 for the annual report, so there is no invoice to prompt you, but the secretary of state can begin administrative dissolution once the anniversary-month deadline passes, and getting the LLC back costs $30 plus a new filing.

$20 paper surcharge on top of the $100 fee

Idaho law adds a $20 manual-data-entry surcharge to any form not produced by the state's e-filing system, so mailing the certificate of organization costs $120 instead of $100.

Where do these numbers come from?

Every fee above was checked against Idaho's own published sources on July 29, 2026 , the Idaho Secretary of State fee schedule, the governing statute, and where a state-level tax applies, the state tax authority. Commercial formation-service pages were not used.

The first-year total is the Certificate of Organization fee plus the first year of any recurring state charge. Where a state's first report is not due until the following year, that is noted above. The five-year total is the filing fee plus five years of recurring charges, which avoids the timing question entirely. Registered-agent service is excluded from all state figures.
