根据车辆价格和州销售税率，估算您购买新车或二手车时需要支付的销售税。
Sales tax on vehicles is typically calculated based on the net purchase price, which is the vehicle's price minus any trade-in value. Some states may have different rules, such as taxing the full vehicle price regardless of trade-in. This calculator uses the more common method of taxing the difference. Always check your local state and county tax laws for the most accurate information.
