Then enter your Missouri location and applicable local tax rate.
Choose how you bought the vehicle:
- Missouri dealer
- Out-of-state dealer
- Private seller

Missouri Car Sales Tax Breakdown
Understanding each part of the calculation makes your final number easier to check.
Vehicle Purchase Price
This is the amount you pay for the vehicle before applicable adjustments.
Trade-In Allowance
A qualifying trade-in can reduce the amount used to calculate Missouri vehicle sales tax.
Dealer or Manufacturer Rebate
A qualifying rebate can reduce the taxable amount used in the calculation.
180-Day Vehicle Credit
Certain vehicle transactions can qualify for an allowance when another vehicle was sold within the applicable 180-day period.
Net Taxable Vehicle Price
The calculator subtracts applicable adjustments from the vehicle price to find the taxable amount.
Net taxable price = vehicle price − qualifying trade-in − qualifying rebate − eligible adjustments
Missouri State Tax
The Missouri state sales or use tax rate is 4.225%.
Local Tax
Local sales or use tax is added to the Missouri state tax. The amount varies depending on the applicable location and tax jurisdiction.
Estimated Missouri Sales or Use Tax
The state tax and local tax are combined to produce your estimated Missouri vehicle tax.
How Is Missouri Car Sales Tax Calculated?
The calculation starts with the taxable price of the vehicle.
Step 1: Calculate the Net Taxable Price
Vehicle price − qualifying trade-in − qualifying rebate = net taxable price
Step 2: Calculate Missouri State Tax
Net taxable price × 4.225% = Missouri state tax
Step 3: Calculate Local Tax
Net taxable price × local tax rate = local tax
Step 4: Add the Taxes
Missouri state tax + local tax = estimated Missouri sales or use tax
Example
Suppose you purchase a vehicle for $30,000 and receive a $5,000 qualifying trade-in.
Your taxable price becomes:
$30,000 − $5,000 = $25,000
The Missouri state tax is:
$25,000 × 4.225% = $1,056.25
Local tax is then added based on the applicable jurisdiction.

Missouri Car Sales Tax Rules You Should Know
Trade-Ins Can Reduce the Taxable Amount
A qualifying trade-in can reduce the vehicle purchase price used to calculate Missouri sales tax.
Keep your trade-in documents because proof may be required in certain transactions.
Rebates Can Reduce the Taxable Amount
A qualifying dealer or manufacturer rebate can reduce the amount used to calculate vehicle tax.
Enter the applicable rebate in the calculator above to see how it changes the taxable amount.
Local Tax Matters
The 4.225% state rate is only one part of your Missouri vehicle tax.
Applicable local sales or use tax is added to the state rate. This is why two buyers can pay different total tax amounts on vehicles with the same purchase price.
Buying a Car Outside Missouri Can Change the Calculation
Buying a vehicle from an out-of-state seller can involve Missouri use tax or an additional Missouri tax payment.
Any tax you already paid to another state may also affect the amount due.
The 90-Day Rule Can Matter
A vehicle owned and operated outside Missouri for at least 90 days before being titled in Missouri can have different Missouri tax treatment.
The rules can be different when the vehicle was owned outside Missouri for less than 90 days.
Title and Registration Are Separate Costs
Sales tax is separate from title and registration fees.
Your total cost can include:
- Missouri sales or use tax
- Title fee
- Title processing fee
- Registration fee
- Plate fees
- Processing fees
- Temporary permit fees
- Other applicable charges
The calculator lets you view these costs separately.
Missouri Car Sales Tax vs. Use Tax
Sales tax and use tax are related, but they are not the same thing.
Sales tax generally applies to taxable retail sales made in Missouri.
Use tax can apply when taxable property is purchased from an out-of-state seller or another seller that does not collect the required Missouri tax and the property is then used in Missouri.
This distinction becomes important when you buy a vehicle outside Missouri.
Are There Legal Ways to Reduce Missouri Vehicle Sales Tax?
Certain situations can reduce the taxable amount.
A qualifying trade-in may reduce the purchase price used for tax.
A qualifying rebate may also reduce the taxable amount.
Certain previously paid taxes, credits, exemptions, or special situations may affect the amount due.
You should use the applicable Missouri rules for your specific transaction rather than assuming that every trade-in, rebate, or purchase qualifies for a tax reduction.
