What this means for your lease
In plain English: tax is added to each monthly payment. Idaho's state-level lease sales-tax rate is 6.00% (before any local add-on).
Your cap-cost reduction (cash down, trade equity, or rebates applied as a down payment) IS taxed in Idaho, so putting more cash down does not escape the tax.
The detail
Idaho treats a motor vehicle lease/rental as a taxable sale; the lessor (a retailer) collects 6% sales tax on each rental/lease payment at the rate in effect on the date each payment is due. Down payment/cap-cost reduction is taxable consideration. Trade-in allowance can be subtracted from the cost to reduce each taxed payment. Method is tax-on-payments.
Local add-ons
Limited local option taxes in a few resort cities; most of Idaho is just the 6% state rate.

Idaho's tax method changes the real cost of a lease — sometimes more than the headline payment does. Drop your numbers into the calculator (we preselect Idaho) to fold the tax into one honest, comparable effective monthly figure.
