sales tax calculator Missouri What Missouri sales tax is, how to calculate it, and vehicle rules you must know

If you’re searching for a missouri sales tax calculator or sales tax calculator Missouri you’re probably trying to estimate the tax on a purchase — commonly a vehicle. Missouri has a flat state sales tax plus city/county surtaxes, and the **state rate is bolded here: ** 4.23%. Local surtaxes are added on top, so the exact rate can vary by ZIP code.

State rate vs. local surtaxes

Missouri charges a flat state sales tax of 4.23%. On top of that, cities, counties and some special districts levy local surtaxes that create a different total rate depending on where you buy or register the vehicle. A sales tax in Missouri calculator must combine:

• the state_rate (always 4.23%) and

• the applicable local_rate (city/county/special district surtaxes).

For accuracy, use ZIP-based/address lookup to pull the local surtax. Example cities include St. Louis, Kansas City, and Springfield.

Why vehicle sales tax is different in Missouri

Vehicle purchases follow special rules compared with general retail. Important differences to include in any Missouri automobile sales tax calculator:

• Trade-in credit: Missouri generally allows a credit for an allowed trade-in value when calculating tax on a vehicle purchase.

• Used-car bands / thresholds: Some rules or simplified tax treatments apply to used vehicles or transactions below certain dollar amounts.

• Dealer collection vs. private-party: Dealers typically collect and remit sales tax at the point of sale; private-party purchases may trigger compensating use tax or different registration procedures.

How to find the exact rate for your purchase

To get an exact number for your situation — especially for a car — try:

• A ZIP-based lookup or address-level sales tax lookup tool.

• Check the city and county tax ordinances when ZIP-level results are ambiguous.

• Ask the dealer for a written tax breakdown before signing.

• For authoritative confirmation, search Missouri Department of Revenue sales tax lookup.

• For private-party purchases, confirm whether you owe compensating use tax at the county clerk or DOR portal.

Manual calculation: copy/paste friendly formulas for WordPress

state_rate = 0.0423
local_rate = 0.0250
total_rate = state_rate + local_rate

purchase_price = 35000.00
trade_in_allowance = 5000.00

taxable_amount = purchase_price - trade_in_allowance
total_sales_tax = taxable_amount * total_rate
final_price = purchase_price + total_sales_tax - trade_in_allowance

Example calculation (practical)

Using the example values — purchase price $35,000, local rate 2.50%, and trade-in $5,000:

1. State rate = 4.23% → 0.0423

2. Local rate = 0.0250

3. Total rate = 0.0423 + 0.0250 = 0.0673 → 6.73% total

4. Purchase price = $35,000.00

5. Trade-in allowance = $5,000.00

6. Taxable amount = $35,000.00 - $5,000.00 = $30,000.00

7. Total sales tax = $30,000.00 * 0.0673 = $2,019.00

8. Final cash outlay = Purchase price + sales tax - trade-in = $35,000 + $2,019 - $5,000 = $32,019.00

Filing, payments and useful admin notes

Dealers usually collect and remit the sales tax at purchase. For private-party purchases, you may owe a compensating use tax when you register the vehicle. Search the Missouri Department of Revenue portal for payment and filing details. Certain purchases may qualify for sales tax exemption.
