Missouri Car Sales Tax Calculator
Calculate the sales tax on your vehicle purchase in Missouri. Tax rates vary by location.
What Is Missouri Car Sales Tax?
Missouri charges a statewide vehicle sales tax of 4.225%. On top of that, cities and counties add their own local sales tax rates, which vary depending on where you register the car.
For example:
- St. Louis City adds 5.425%
- Kansas City adds 4.625%
- Springfield adds 3.875%
- Columbia adds 3.725%
- St. Charles County adds 2.725%
That means your total sales tax could be anywhere between 7% and over 9% of your vehicle’s taxable price.
How Is Car Sales Tax Calculated in Missouri?
The tax is applied to your vehicle’s net price. That’s the purchase price minus any trade-in value.
For example:
- Vehicle price: $32,000
- Trade-in value: $8,000
- Taxable amount: $24,000
If you live in Kansas City, where the total tax rate is 4.225% (state) + 4.625% (local) = 8.85%, your estimated sales tax would be:
$24,000 × 8.85% = $2,124
That’s a big chunk of money, and why calculating your tax before heading to the dealership is essential.

Example Walkthrough Using the Calculator
Let’s run through a sample calculation with the Missouri car sales tax calculator:
- Vehicle Price: $30,000
- Trade-in Value: $5,000
- Location: St. Louis City (state + local tax = 9.65%)
Steps:
- $30,000 – $5,000 = $25,000 taxable amount
- State tax: $25,000 × 4.225% = $1,056.25
- Local tax: $25,000 × 5.425% = $1,356.25
- Total estimated tax = $2,412.50
That’s nearly the cost of a nice used car, which shows why calculating before you buy matters.
Tips for Missouri Car Buyers
- Don’t forget registration and title fees. Sales tax is only one part of the total cost of ownership.
- Use trade-ins strategically. A higher trade-in value means less taxable amount.
- Shop location wisely. Since local tax rates differ, where you register the car can affect your total bill.
- Check exemptions. Some vehicles, such as those purchased by non-residents, may qualify for exemptions.
