Estimate the sales-tax difference by state

Roughly the purchase price times your state's sales tax rate, because Montana charges none. On a $100,000 vehicle that is about $8,800 in California, $8,200 in Texas, and $7,000 in Florida, against about $950 to $1,750 to set up the LLC and registration in year one and $125 a year after.

It is an estimate. The calculator uses each state's average combined state and local sales tax rate against your price and our registration fee for that MSRP bracket. Some states tax vehicles at a flat rate or a different base, and home-state use tax can apply to a vehicle kept there, so confirm with a tax professional.

It depends on where the vehicle is primarily used and your state's rules. Some states assess use tax when a resident's vehicle is used in-state. We are a formation and registered-agent service, not tax advisors; consult a tax professional about your specific situation before registering.

Montana is one of five states with no general sales tax, alongside Oregon, New Hampshire, Delaware, and Alaska. Because the LLC that buys and registers the vehicle is a Montana entity, the purchase is not subject to Montana sales tax. Other fees, like registration, still apply and pass through at cost.
