Buying a car is, no doubt, a major expense. Beyond the vehicle's base price, numerous additional costs can significantly inflate the total out-of-pocket expenditure. One highly variable, yet inevitable expense encountered during car purchase has to do with sales tax. Charged in most U.S states, the sales tax on a vehicle can stir up quite a shock, especially when it accounts for a sizable chunk of the vehicle's price. While some states lean towards leniency with reduced sales tax requirements, others adopt a higher tax rate. Interestingly, a small selection of states, including Alaska, Delaware, Montana, New Hampshire, and Oregon, levies no car sales tax at all.
