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.
