Why Founders Choose Montana for Their LLC

Montana has no sales tax, which some consider for vehicle, aircraft, and equipment titling LLCs. Important legal note: registering a Montana LLC to avoid sales tax on a vehicle or equipment primarily used in another state (such as California or Texas) may constitute tax evasion under that state’s laws, not legal tax avoidance. Many states aggressively audit and assess back taxes, interest, and penalties for this practice. Consult a tax attorney licensed in your home state before using a Montana LLC for vehicle or equipment titling.

How Do You Start an LLC in Montana?

Filing in Montana costs $35 in state fees. Montana publishes no standard processing time, so plan around the filing itself rather than a promised turnaround. You'll file Articles of Organization, appoint a registered agent, and complete any state-specific requirements before opening for business.

That is the filing fee alone. For the first-year and five-year totals, see Montana LLC cost.
