How the Calculation Works

The auto sales tax calculator for Missouri uses the following formula to calculate the total sales tax:

Total Sales Tax = (Vehicle Price × State Tax Rate) + (Vehicle Price × Local Tax Rate)

Where:

Vehicle Price is the purchase price of the vehicle
State Tax Rate is the Missouri state sales tax rate (4.225%)
Local Tax Rate is the additional sales tax rate imposed by the county where the vehicle will be registered

The calculator then adds the state and local tax amounts to get the total sales tax that will be applied to the vehicle purchase.

Worked Examples

Example 1: Vehicle Purchased in St. Louis City

If you're purchasing a vehicle for $25,000 in St. Louis City:

Total Sales Tax = ($25,000 × 4.225%) + ($25,000 × 1.775%)

= $1,056.25 + $443.75

= $1,499.99

The total sales tax for this purchase would be $1,500.

Example 2: Vehicle Purchased in Kansas City

If you're purchasing a vehicle for $30,000 in Kansas City:

Total Sales Tax = ($30,000 × 4.225%) + ($30,000 × 1.0%)

= $1,267.50 + $300.00

= $1,567.50

The total sales tax for this purchase would be $1,567.50.
