Florida Car Tax & Out-the-Door Calculator
What will this car really cost out the door in Florida?
Enter the selling price, qualifying trade allowance, county rate, and written fee lines to build a Florida planning estimate. Works for any make or model, new or used.
How the Florida out-the-door math works
Out the door = selling price − qualifying trade allowance + taxable dealer fee + 6% state sales tax + county surtax + estimated title and registration. The state tax is calculated on taxable selling-price lines after the qualifying trade allowance.
The county discretionary surtax only applies to the first $5,000 of the price — that's why it's capped between $0 and $100 no matter how expensive the car is. Full breakdown and a worked $40,000 example are in the Florida out-the-door price guide, and the fee side is covered in Florida dealer fees explained.
Questions Florida buyers ask
How much is sales tax on a car in Florida?
Florida charges 6% state sales tax on the vehicle price after any qualifying trade-in credit, plus a county discretionary surtax of 0% to 2% that applies only to the first $5,000 of the price — so the surtax caps at $0 to $100. On a $35,000 taxable amount in a 1% county that’s $2,100 state tax + $50 surtax = $2,150.
Does a trade-in lower my Florida car tax?
Yes. Florida subtracts a qualifying trade-in from the price before tax is calculated, as long as the trade is part of the same dealer transaction. Trade a $5,000 car on a $40,000 purchase and you’re taxed on $35,000, saving $300 in state tax. A manufacturer rebate does NOT reduce the taxable amount the way a trade-in does.
Does the county surtax apply to the whole price?
No. The discretionary county surtax applies only to the first $5,000 of a single vehicle’s price, so even on a $70,000 truck it caps at a small fixed amount ($50 in a 1% county, up to $100 at the highest 2% rate). Only the 6% state tax applies to the full price.
What fees come on top of tax in Florida?
Title, registration, tag or plate, electronic filing, lien, and dealer charges depend on the buyer and transaction. Use the written buyer's order instead of assuming a standard fee.
Is this Florida car tax calculator exact?
It is a planning estimate. Your county rate, taxable line items, trade structure, tag and title situation, and the written buyer’s order determine the final number.
