Name a registered agent
If you form an LLC or corporation, Montana needs a registered agent with a physical in-state address. You can be your own agent if you're available during business hours, or hire a service for about $100–$150/year.
Get your EIN from the IRS
An Employer Identification Number is free from the IRS and takes a few minutes online. You need it to open a business bank account and to hire.
