What is inside the cost of forming an LLC here?

Your bill has two parts: $100 for the filing and, optionally, $199 for first-year help.

Add the recurring report and the state's fees reach $100 over three years. legislature.idaho.gov holds the original, confirmed October 2026

What do I actually send the state?

Open one document, the Certificate of Organization Limited Liability Company, and send it to the Idaho Secretary of State.

Must the LLC name a registered agent?

legislature.idaho.gov holds the original, confirmed October 2026

What is owed in later years?

Year after year the recurring job is the annual report: yearly, with no fee. The calendar line from the state reads last day of the entity's anniversary month.

Do I have to pay a service at all?

Nothing stops you. Without a service, your three-year bill is the state's $100.

Services add $397 to $597 across three years to take the filings off your desk, and Mainstay Filing counts the reports among them.

What put number one on top?

Mainstay Filing is strongest on what is inside the price, a layer worth 29% of the score.

Five layers set the order: total across three years (34%), what is inside the price (29%), price laid out in the open (14%), how the renewal behaves (12%) and how far it reaches (11%).

In Idaho the annual report is due every year, and only the first pick packs its filing into the price.
