The price on the windshield is not the only number on your bill. Here is a plain-English breakdown of the taxes and fees you can expect when you buy a used car in Florida — with an example for Santa Rosa County buyers in Navarre, Gulf Breeze, Milton and Pace.
Key Takeaways
- Florida charges a 6% state sales tax on the vehicle’s taxable price.
- Your county may add a discretionary sales surtax — but only on the first $5,000 of the price.
- The surtax is based on the county where you will register the vehicle, not where you buy it.
- In Florida, a trade-in generally reduces the amount you pay sales tax on.
- Florida law requires advertised prices to include all dealer fees except tax, tag, title and registration.
What is the sales tax on a used car in Florida?
Florida’s state sales tax is 6% of the vehicle’s taxable price. On top of that, most counties add a discretionary sales surtax. For a single item like a car, that county surtax applies only to the first $5,000 of the price — so it adds a relatively small, capped amount.
How much is the county surtax in Santa Rosa County?
As of 2026, Santa Rosa County’s discretionary surtax is 1%. Because it applies only to the first $5,000, the most a Santa Rosa County resident pays in county surtax on a vehicle is about $50. Rates change from time to time, so check the Florida Department of Revenue’s current surtax chart (Form DR-15DSS) before you buy.
Important: for vehicles, the surtax is based on the county shown on your registration address. If you live in Okaloosa or Escambia County and buy from us in Navarre, your own county’s rate applies.
Does a trade-in lower my sales tax in Florida?
Generally, yes. Florida calculates sales tax on the price after your trade-in allowance is deducted. For example, if you buy a $20,000 vehicle and receive $6,000 for your trade-in, sales tax is figured on about $14,000 instead of $20,000. That can save you hundreds of dollars — one more reason to get a trade-in offer.
Example: a $15,000 used car in Santa Rosa County
- State sales tax: 6% × $15,000 = $900
- County surtax: 1% × first $5,000 = $50
- Estimated sales tax total: about $950 (before tag, title and registration)
This is a simplified illustration, not tax advice. Your actual amount depends on the final price, trade-in, county of residence and current rates.
What are dealer fees in Florida?
Most Florida dealers charge a pre-delivery service fee (often called a “dealer fee” or “doc fee”). Florida does not cap this fee, but it does regulate how it is advertised: under section 501.976 of the Florida Statutes, a dealer’s advertised price must include all fees and charges the customer must pay, except state and local taxes, tag, registration and title fees. Florida also requires specific disclosure language anywhere the predelivery charge appears as a line item.
At K&S Auto Sales, our advertised prices include our dealer fees, so the price you see is the price you start from. See our pricing disclaimer for details.
What about tag, title and registration?
Tag, title and registration fees are set by the state and county and depend on the vehicle’s weight, whether you are transferring an existing plate, and whether the vehicle (or you) are new to Florida. First-time Florida registrations typically carry a one-time initial registration fee. Your dealer collects these fees and handles the paperwork with the county tax collector, and you will usually drive away on a temporary tag while your plate and registration are processed.
The bottom line
Budget for roughly 6–7% in sales tax plus tag and title fees on top of the advertised price, and remember that a trade-in can reduce your tax. Questions about a specific vehicle? Call us — we are happy to walk through an out-the-door estimate with you.
