How to Form an LLC in Idaho (Step by Step)
- Choose a name. Pick a distinguishable name that includes "LLC" and check it is available on the Idaho Secretary of State website before you file.
- Appoint a registered agent. Name a person or service with a physical street address in Idaho who can receive legal mail during business hours — be your own for free, or hire one (see our registered agent guide).
- File your formation document. File the Articles of Organization (called a Certificate of Formation in some states) with the Idaho Secretary of State and pay the $100 filing fee.
- Create an operating agreement. Not filed with the state, but it records who owns what and how the LLC is run — banks and partners will ask for it.
- Get an EIN. Apply free on the IRS website in about 10 minutes — see our EIN guide. You need it to hire, pay taxes, and open a business account.
- Open a business bank account and stay compliant. Keep business money separate (see our business bank account guide), then keep up with Idaho's recurring fees — Annual report, no fee — so the LLC stays in good standing (see our annual reports guide).
