Florida Car Sales Tax Calculator
Estimate Florida motor-vehicle tax by county and see how a qualifying trade-in changes the taxable amount.
Start with the deal price.
Use the negotiated selling price, not the monthly payment.
Florida uses two tax layers
The calculator shows the 6% state portion and the county discretionary surtax separately. For a motor vehicle, the county portion is generally limited to the first $5,000 of the taxable amount.
Which county rate is used?
Select the county associated with the transaction's applicable Florida surtax location. The tool displays the loaded 2026 rate so the assumption is visible.
Rebates and discounts
Dealer discounts and genuine price reductions are separated from cash rebates because the labels can receive different tax treatment. Confirm the dealer's taxable-base calculation when an incentive is involved.
The calculator distinguishes official fixed rules from local or user-entered estimates. Dealer worksheets and licensing-office totals remain the final transaction records.
