The Montana LLC Vehicle Loophole
You may have heard of people forming a Montana LLC strictly to buy a luxury car, airplane, or RV to avoid paying sales tax. While this is technically legal in Montana, you must be extremely careful. Your home state (like California or New York) may aggressively penalize you for tax evasion if the vehicle spends too much time there.
