How it works
Subtract the trade-in value from the price, then multiply by the sales tax rate. If the trade-in is worth more than the price, the taxable amount is zero.
In the Missouri example, the state vehicle sales tax rate is 4.225%, and local taxes can add to it. Enter the full rate that applies to your purchase, and check it with the seller or the state tax office.
Worked example
A vehicle at $30,000.00 with a trade-in of $8,000.00 is taxed on $22,000.00. At 4.23%, the sales tax is $929.50, and the total after trade-in comes to $22,929.50.
Questions
Is the trade-in always deducted?
Not everywhere. Some places tax the full price, and some only tax the difference. Check the rule where you buy, and set the trade-in to zero to see the full-price figure.
Do fees get taxed?
This shows tax on the price only. Title, registration and dealer fees may be taxed or charged separately, depending on where you live.
Where do I find my local rate?
Rates are set by the state and by cities and counties. The seller can tell you the rate on the sale, and the state tax office publishes rate tables.
