Before you purchase a car, it’s critical to know the associated sales taxes and fees, as they can be hundreds or thousands of dollars.
Idaho falls in the average range of national car sales tax brackets. We will cover the state sales tax and other fees related to vehicle purchases in Idaho and discuss various scenarios that can or cannot discount tax fees.

The car sales tax rate for Idaho is 6% on the purchase price of each vehicle you buy.
However, there may be an extra local or county sales tax added onto the base 6% state tax. Local tax rates range from 0% to 3%, with an average of .074%.
It’s easy to calculate the state sales tax on your vehicle purchase in Idaho. Take your original purchase price, deduct any trade-in values, and multiply against the sales tax rate.
For example, imagine you are purchasing a vehicle for $60,000 with the state sales tax of 6%. You trade-in a vehicle for $9,000 and get an incentive for $1,000. Idaho does not charge tax on trade-ins, but does on rebates, so you would only subtract the $9,000 trade-in value from the car cost, to get $51,000, which is the taxable amount.
In this example, multiply $51,000 by .06 to get $3,060.
Calculate Car Sales Tax in Idaho Example:
- Initial Car Price: $60,000
- Sales Tax Rate: 6%
- Trade-In Amount: $9,000
- Rebate/Incentive Amount: $1,000
Sales Tax = ($60,000 - $9,000) * .06
Sales Tax = $3,060
Remember that the total amount you pay for a car (out the door price) not only includes sales tax, but also registration, and dealership fees.

The trade-in value of your current car will not be subject to the state sales tax.
For example, if you’re purchasing a new vehicle at $50,000, and you have a trade-in value from your current car at $10,000, then you will only be taxed on the difference of $40,000.
Private sales of vehicles in Idaho are subject to the 6% sales tax. After your purchase, you will need to go to the Idaho Department of Motor Vehicles to pay the sales tax along with other DMV fees.
Rebates and dealer incentives are subject to the state sales tax meaning you’ll have to pay sales tax regardless of the rebates and dealer incentives.
For example, if a vehicle’s sticker price is $50,000 and you have a rebate of $1,000, and the dealership is offering a $5,000-off holiday incentive, you will still be responsible for paying the full state sales tax on the sticker price of $50,000.
In addition to sales tax, the Idaho DMV sets related fees that must be paid. These fees are based on many factors like vehicle age, type and weight of vehicle, inspection requirements, your county of residence, and other considerations.
The average DMV costs are $62 for gas-powered vehicles, but may be closer to $92 with other types of vehicles and considerations.
Along with purchasing your car, you will be subject to dealership fees like documentation fees. This can vary from dealer to dealer.
The median document fees add up to $265 in Idaho, and there is no law limiting “doc” fee prices.
