How to Form an LLC in Idaho: Step by Step
Choose a Name for Your LLC
Your LLC name must be unique in Idaho and include "LLC" or "Limited Liability Company." Check availability on the Idaho Secretary of State website before filing. You can also reserve a name for a small fee (typically $10–$25) if you're not ready to file.
Appoint a Registered Agent
Idaho requires every LLC to have a registered agent — a person or company with a physical Idaho address who can receive legal documents on your behalf. You can be your own registered agent or use a service ($100–$300/year) for privacy and reliability.
File Articles of Organization
File your LLC formation documents (Articles of Organization) with the Idaho Secretary of State. The 2026 state filing fee is $100. Standard processing takes 3–5 business days. You can file online at the Idaho Secretary of State website or through a formation service.
Create an Operating Agreement
An operating agreement outlines how your LLC is managed, how profits are distributed, and what happens if a member leaves. While not always legally required in Idaho, it's strongly recommended — especially if you have multiple owners. Many banks require it to open a business account.
Get an EIN from the IRS
Apply for a free Employer Identification Number (EIN) at IRS.gov. You'll use it to open a business bank account, hire employees, and file your business taxes. The IRS issues EINs immediately online.
File Annual Reports & Maintain Compliance
Idaho requires an annual report to keep your LLC in good standing, but there is no fee to file it. Mark your calendar to file on time to avoid penalties.
