How to start an LLC in Montana, step by step

1. Choose and check your LLC name. Your name must be unique in Montana and include "LLC" or "Limited Liability Company." Search the Montana Secretary of State business database to confirm it's available, and grab the matching domain while you're at it.
2. Appoint a registered agent. Every Montana LLC needs a registered agent with a physical address in the state to receive legal mail. You can be your own agent or hire a service; here's what a registered agent is and how to choose.
3. File your Articles of Organization. Submit the formation document to the Montana Secretary of State, online or by mail, and pay the roughly $35 fee. Approval typically takes immediately online in most cases.
4. Create an operating agreement. This internal document sets out ownership and how the LLC is run. It isn't always filed with the state, but it's strongly recommended even for single-member LLCs.
5. Get an EIN from the IRS. This free federal tax ID lets you open a business bank account, hire employees, and file taxes. Learn what an EIN is and how to apply in minutes.
6. Handle licenses, permits, and taxes. Depending on your industry and city, you may need local business licenses and a seller's permit for sales tax. See how to register a business for the full sequence.

Should you form your LLC in Montana or another state?

If you live and do business in Montana, forming here is almost always the right choice. Forming in a "cheaper" or more famous state usually backfires, because you'll still have to register as a foreign LLC in Montana anyway, which means paying two sets of fees and maintaining two registered agents. For the bigger picture, read what an LLC is and whether an LLC is right for you versus staying a sole proprietor.
