Buying a car in Vermont means paying a 6% Purchase and Use Tax at the DMV — a tax that trips up out-of-state buyers because it is administered separately from the general sales tax and follows its own trade-in rules. This calculator applies the 6% rate correctly: it subtracts a trade-in from the taxable base while keeping rebates taxable, then shows your estimated out-the-door total.
How it works
Vermont’s rule has three moving parts:
- Taxable base = purchase price − trade-in. A vehicle traded in to a dealer reduces the amount subject to tax.
- Rebates stay taxable. A manufacturer rebate lowers the cash you hand over but does not reduce the base the 6% is calculated on.
- 6% Purchase and Use Tax is then applied to that base.
The tool also adds a dealer documentation fee (non-taxable) to estimate the full out-the-door
figure: (price − trade − rebate) + tax + doc fee.
Example and notes
A $28,000 vehicle with a $6,000 trade-in is taxed on $22,000, producing $1,320 in Vermont Purchase and Use Tax. A $1,500 manufacturer rebate cuts your cash price but not the tax — the 6% still applies to the $22,000 base.
One important catch: Vermont bases the tax on the greater of your purchase price or the clean trade-in book value. If you report an unusually low price, the DMV may tax the book value instead.
