How to Form an LLC in Montana (2026)
Everything you need to start a Montana LLC — from choosing a name to staying compliant after formation.
Form in your home state if you operate locally
Unless you have investors or specific legal needs, forming your LLC in Montana (where you do business) is simpler and cheaper than Delaware or Wyoming — you avoid registering as a foreign LLC in two states.Step-by-Step: Forming a Montana LLC
Choose a name for your LLC
Your LLC name must be unique in Montana and must include "Limited Liability Company," "LLC," or "L.L.C." Search the Montana Secretary of State's business name database before filing to confirm availability. You can typically reserve a name for 30–120 days for a small fee.
Appoint a registered agent
Every Montana LLC must have a registered agent — a person or company with a physical Montana address available during business hours to receive legal notices and state correspondence. You can serve as your own registered agent, or hire a registered agent service ($50–$150/year) for privacy and reliability.
File your Articles of Organization
Submit your Articles of Organization to the Montana Secretary of State along with the $35 filing fee. Standard processing takes approximately 5 business days. Expedited processing is available: 1.
Create an Operating Agreement
An Operating Agreement governs how your LLC is managed, how profits are split, and what happens if a member leaves. Montana may not require one, but having one is strongly recommended — it protects your limited liability status and prevents disputes.
Get an EIN from the IRS
Apply for a free Employer Identification Number (EIN) at irs.gov/ein. You'll need it to open a business bank account, hire employees, and file taxes. The application takes about 10 minutes and your EIN is issued immediately online.
Open a business bank account
Keep business finances strictly separate from personal accounts. Commingling funds is one of the most common reasons courts "pierce the corporate veil" and hold LLC members personally liable. Bring your EIN, Articles of Organization, and Operating Agreement to the bank.
Get business licenses and permits
Depending on your industry and location, you may need federal, state, or local business licenses. Check with your city and county clerk's office and the Montana state licensing portal for requirements specific to your business type.
Stay compliant after formation
File your annual report and pay the $15 annual fee any state and local tax filings.
Montana has no sales tax — beneficial for product-based businesses.
