The 4 steps in Montana

1

Pick a name that works in Montana

Your name must be distinguishable from other Montana businesses and include a designator like “LLC” or “Limited Liability Company.” Search the state's business database before you file.

2

File the paperwork

You file Articles of Organization with the Secretary of State online through the state's business portal. The filing fee is $35. Also write a simple operating agreement — it's free, and it keeps your liability protection clear.

3

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.

4

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 Montana 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.

Good to know

Montana is the cheapest state in the country to form an LLC, at just $35, and has no general sales tax.
