How to form an LLC in Montana — step by step
Search your business name
Verify your desired LLC name is available in Montana. The name must include "Limited Liability Company," "LLC," or "L.L.C." Use the Montana Secretary of State business search tool.
Choose your registered agent
Designate a registered agent with a physical Montana address available during business hours. You can serve as your own agent or use a registered agent service ($50–$300/year).
File articles of organization
Submit your articles of organization to the Montana Secretary of State online. Pay the $35 filing fee.
Wait for approval
Standard processing takes approximately 5 business days. You will receive a stamped copy of your articles once approved.
Create an operating agreement
Draft an operating agreement outlining ownership, management structure, profit sharing, and member responsibilities. Montana does not require an operating agreement by law, but it is strongly recommended for all LLCs.
Get your EIN
Apply for a federal Employer Identification Number (EIN) free at IRS.gov. Takes about 10 minutes online. Required for business bank accounts, hiring employees, and filing taxes.
Open a business bank account
Use your EIN, articles of organization, and operating agreement to open a dedicated business checking account. Keeping business and personal finances separate is essential for maintaining your liability protection.
File annual reports & pay taxes
File your Montana annual report ($20) by April 15 each year. Keep your registered agent updated and pay any applicable state taxes.
