Questions people ask us
How accurate is this vehicle sales tax estimate?
It uses your state's base vehicle tax rate. Local county and city add-ons, trade-in credits, and category quirks can move the real number, usually upward by 1 to 3 points. Your state guide lists the detail, and a real quote from us itemizes the exact figure.
Does a Montana LLC eliminate this tax?
Montana charges no sales tax, so a vehicle titled to a Montana LLC pays none at purchase. Whether your home state can still assess use tax on you depends on where the vehicle is kept and your state's enforcement. Seven states actively pursue it. The calculator's verdict includes that risk because leaving it out would be selling, not calculating.
What does the "worth it" verdict weigh?
The estimated home-state tax against the full Montana cost: our $1,249 package, Montana's $825 luxury fee where the vehicle exceeds $150,000, and annual maintenance. Then it overlays your state's enforcement posture, because expected value includes the audit scenario.
