The 4 steps in Idaho
Pick a name that works in Idaho
Your name must be distinguishable from other Idaho businesses and include “LLC,” “L.L.C.,” “Limited Liability Company,” or “Limited Company.” Search SOSbiz first.
File the paperwork
You file a Certificate of Organization with the Idaho Secretary of State, online through SOSbiz or by mail. Online filing costs $100; paper costs more. The filing fee is $100. Also write a simple operating agreement — it's free, and it keeps your liability protection clear.
Get your free EIN
Apply at IRS.gov and get your Employer Identification Number immediately, for free. You'll need it for taxes and your business bank account.
Open a business bank account
Bring your approved Articles of Organization, EIN, and operating agreement. Keeping business money separate is what makes the liability protection hold.
Optional: name a registered agent service
Every Idaho LLC needs a registered agent with a physical address in the state. You can be your own for free — or pay a service to keep your address private. Learn how registered agents work.
Idaho charges nothing to keep your LLC active each year, but the report is still required. Set a reminder for your anniversary month.
File directly with the Idaho Secretary of State.
