How is the vehicle sales tax calculated in Colorado?

Answer: B — Based on the purchase price minus trade-in value

The correct method for calculating vehicle sales tax in Colorado is based on the purchase price of the vehicle minus any trade-in value. When you buy a vehicle, the state allows you to reduce the taxable amount by the value of any vehicle you trade in as part of the transaction.

For example, if you purchase a vehicle priced at $20,000 and you trade in a vehicle worth $5,000, you will be taxed on the difference of $15,000. This practice is designed to ease the financial burden on buyers and is consistent with the principle that taxpayers should only pay tax on their actual cash outlay. In contrast, other options do not represent how sales tax is calculated.

The market value of the vehicle is generally not used for sales tax purposes because the taxable amount is specifically tied to the transaction price rather than an independent assessment of the vehicle’s worth.
