The Short Answer
In Florida you pay 6% state sales tax on the vehicle's price (after any trade-in credit), plus a county discretionary surtax of 0% to 1.5% that applies ONLY to the first $5,000 of the price — so the surtax tops out at $50 (1% counties) or $75 (1.5% counties) no matter how expensive the car is. On top of tax, expect a one-time title fee around $77, a one-time $225 initial registration fee for a newly registered vehicle (plus a weight-based tag fee), and a dealer documentation fee that Florida does NOT cap by statute — most dealers charge roughly $799 to $999. On a $40,000 vehicle with a $5,000 trade-in in a 1% county, a realistic out-the-door total lands near $38,526 (worked line by line below).
The 6% Florida State Sales Tax
Florida charges a flat 6% state sales tax on motor vehicle purchases, and unlike the county surtax, the 6% applies to the entire taxable price of the car — there's no ceiling. The taxable price is the agreed selling price of the vehicle before tax, after subtracting any qualifying trade-in. So a $35,000 taxable amount generates $2,100 in state tax (35,000 x 0.06). This rate is set in Florida Statute Chapter 212 and is the same in all 67 counties; what changes county to county is only the surtax layered on top.
The County Discretionary Surtax — and the First-$5,000 Rule
Each Florida county can add a discretionary sales surtax on top of the 6%, ranging from 0% to 1.5% depending on the county. The critical rule for car buyers: on a single big-ticket item like a vehicle, the surtax applies ONLY to the first $5,000 of the price. That caps the surtax at a small fixed dollar amount — $50 in a 1% county (Miami-Dade, Broward, Palm Beach, Orange) or $75 in a 1.5% county (Hillsborough, Duval, Pinellas) — even on a $60,000 truck. Some counties (for example Citrus and Hernando have been at 0%) charge no surtax at all. Surtax is based on the county where the vehicle is registered/delivered, not where the dealer sits. Rates change over time, so confirm your county's current rate before signing.
How a Trade-In Lowers Your Tax
Florida lets you subtract the value of a trade-in from the vehicle's price BEFORE tax is calculated, which is one of the biggest legitimate ways to cut your tax bill. If you buy a $40,000 car and trade one in for $5,000, you're taxed on $35,000, not $40,000 — saving you 6% of $5,000, or $300, in state tax alone. The trade must be part of the same transaction with the dealer; selling your old car privately and bringing cash does NOT earn the tax credit. A manufacturer rebate, by contrast, generally does not reduce the taxable amount the way a trade-in does — the tax is still figured on the price before the rebate in most cases.
Title and Registration Fees
Beyond tax, Florida charges government fees that are the same whether you buy from a dealer or a private seller. The title fee is about $77.25 for a paper title (an electronic title is cheaper, around $75/$80 with the electronic processing). For a vehicle being registered in Florida for the first time, there's a one-time $225 initial registration fee — this is waived if you transfer an existing Florida plate to the new car. Then there's the annual base registration (tag) fee, which is weight-based: roughly $14.50 to $32.50 for passenger cars and higher for SUVs and heavier vehicles, plus about $28 for a new metal plate. Altogether, the title-plus-tag-plus-initial-registration bucket on a first-time registration commonly runs $250 to $400.
Dealer Doc Fees — Does Florida Cap Them?
This is where buyers get surprised: Florida does NOT have a statutory cap on dealer documentation fees (sometimes labeled a dealer fee, doc fee, or pre-delivery service charge). We verified this against multiple 2026 industry sources — Florida is consistently listed as a no-cap state. In practice most Florida dealers charge somewhere between roughly $799 and $999, and Florida's average is among the highest in the country (commonly cited near $999). Florida law does require the fee to be disclosed in writing with specific statutory language, but disclosure is not the same as a price limit — the dollar amount is set by the dealer. The doc fee is itself taxable as part of the price. Treat it as a real, negotiable-in-spirit line even though many dealers hold firm on it; the smart move is to compare the full out-the-door number, not the doc fee in isolation.
Worked Example: $40,000 Vehicle, Out the Door
Here's the full math for a $40,000 vehicle with a $5,000 trade-in, registered in a 1% surtax county (like Broward, Miami-Dade, Palm Beach, or Orange), first-time Florida registration: 1) Vehicle selling price: $40,000.00 2) Less trade-in credit: -$5,000.00 3) Taxable amount: $35,000.00 4) Florida 6% state sales tax (6% x $35,000): +$2,100.00 5) County surtax, 1% on first $5,000 only: +$50.00 6) Dealer doc fee (typical): +$999.00 (note: also taxable in a full deal — see below) 7) Title fee: +$77.25 8) Initial registration + tag + plate (first-time): +$300.00 (approx) Subtotal before deducting the trade you already handed over: $40,000 + $2,100 + $50 + $999 + $77.25 + $300 = $43,526.25, minus the $5,000 trade-in = $38,526.25 out the door. Note on tax base: dealers typically fold the doc fee into the taxable price, which would add about $60 more in tax (6% of $999). We kept the example clean above; in a real deal expect the doc fee to be taxed, nudging the total up by roughly that amount. The honest takeaway: on a $40K car, plan for roughly $2,100-$2,200 in tax, ~$1,000 in doc fee, and ~$375-$400 in government title/tag fees on top of the price — with the trade-in shaving real dollars off the tax.
