Buying a boat in Florida involves more than just the sticker price. Florida law requires buyers to pay a 6% state sales tax on every boat purchase — plus a small local “surtax” that varies by county. This guide breaks down every piece of that calculation in plain English, with real examples at each step.
Whether you’re buying a fishing skiff or a 60-foot sportfisher, the same formula applies to every boat sale in Florida. The calculator follows five clear steps. Let’s walk through each one.
Step 1 — Calculate Your Taxable Base
Before any tax is applied, the calculator figures out the taxable base — the amount of money that will actually be taxed. This is simple: it’s your purchase price minus any trade-in allowance.[2]
Taxable Base = Purchase Price − Trade-In Value
Florida allows you to deduct the value of a boat or boat-related equipment you’re trading in toward the new purchase. This is a dollar-for-dollar reduction before any tax is calculated.[2] Note: only boat-related property qualifies — you cannot deduct a car or real estate trade-in.
Example A
No Trade-In
Purchase Price: $50,000
Trade-In Value: $0
Taxable Base: $50,000
Full price is taxed — nothing to deduct.
Example B
With a $10,000 Trade-In
Purchase Price: $30,000
Trade-In Value− $10,000
Taxable Base: $20,000
Only $20,000 moves forward to the tax calculation.
Keep in mind: if your trade-in value equals or exceeds the purchase price, there’s nothing to tax — but the calculator will flag this as an input error to make sure the numbers are entered correctly.
Step 2 — Apply the 6% State Sales Tax
Florida’s state sales tax rate on boats is 6%, applied to the full taxable base you calculated in Step 1. This rate has not changed in recent years — bills proposing higher rates have been introduced in the legislature, but none are in effect for 2026.
The formula: State Tax = Taxable Base × 6%
This 6% applies whether the boat is brand new or used, bought from a dealer or a private seller. For private-party sales, buyers pay this tax directly to the county tax collector’s office when registering the boat.[3]
Example A
$50,000 Taxable Base
Taxable Base: $50,000
State Rate× 6%
State Tax$3,000
Example B
$20,000 Taxable Base (after trade-in)
Taxable Base: $20,000
State Rate× 6%
State Tax: $1,200
Step 3 — Find and Apply Your County Surtax
On top of the state’s 6%, most Florida counties add their own small discretionary surtax. This is where your specific county matters. But here’s the key detail: the county surtax only applies to the first $5,000 of your taxable base — no matter how expensive the boat is.
Surtax = County Rate × MIN($5,000, Taxable Base)
Even on a $500,000 yacht, the county surtax is calculated on just $5,000. This cap on the surtax base is set by Florida statute and applies uniformly across all counties.
County surtax rates for 2026, based on Florida DOR Form DR-15DSS, range as follows:
| Surtax Rate | # of Counties | Notable Counties | Max Surtax on $5,000 |
|---|---|---|---|
| 0% | 2 | Citrus, Collier | $0 |
| 0.5% | 7 | Orange, Palm Beach, Lee, Volusia | $25 |
| 1.0% | 34 | Broward, Pinellas, Sarasota, Pasco | $50 |
| 1.5% | 22 | Duval, Hillsborough, Monroe, Osceola | $75 |
| 2.0% | 2 | Miami-Dade, Hamilton | $100 |
Example A — Miami-Dade (2.0%)
$50,000 Taxable Base
Surtax applies to first…$5,000
Miami-Dade Rate× 2.0%
County Surtax$100
The remaining $45,000 of the boat’s price is not subject to surtax.
Example B — Orange County (0.5%)
$20,000 Taxable Base
Surtax applies to first…$5,000
Orange County Rate× 0.5%
County Surtax: $25
Orange County’s lower rate means minimal local tax on top.
The surtax rate is based on the county where the boat is delivered or where it will primarily be used and registered — not necessarily where the dealership is located.[6]
Step 4 — Apply the $18,000 Tax Cap
Florida law sets an absolute maximum on how much combined tax (state + county surtax) you can owe on a single boat purchase: $18,000.[7] This cap exists to keep taxes on very expensive boats from becoming prohibitive.
Final Tax = MIN(State Tax + County Surtax, $18,000)
If the sum exceeds $18,000, you pay exactly $18,000 — no more.
For most buyers, this cap is never reached. To hit it with just the 6% state tax, you’d need a taxable base of $300,000 or more. But on large yachts and sportfishers, the cap provides real, meaningful savings.
Example A — Cap Not Reached
$50,000 Boat in Miami-Dade
State Tax: $3,000
County Surtax: $100
Subtotal: $3,100
Cap ($18,000): Not triggered
Total Tax Owed $3,100
Example B — Cap Triggered
$400,000 Boat in Broward
State Tax (6%)$24,000
County Surtax$50
Subtotal$24,050
Cap Applied⬇ $18,000
Total Tax Owed $18,000
Step 5 — Check for Exemptions
Certain buyers pay zero Florida sales tax — regardless of the boat’s price. There are two main exemptions recognized by the calculator.
Tax: $0
Nonresident Exemption
If your permanent home is outside Florida, you may qualify for a full exemption.[8] The boat must be removed from Florida within 90 days of purchase (or just 10 days for smaller vessels under 5 net tons). You’ll need documentation such as fuel receipts and out-of-state registration to prove the boat left Florida.
Tax: $0
Military Exemption
Florida residents on active military duty stationed outside Florida can claim an exemption.[9] The buyer must sign a Certificate of Entitlement confirming the boat will stay out of Florida for at least six months. If that condition is later violated, back taxes become due.
Out-of-State Delivery
If the boat is physically delivered to you outside of Florida, no Florida sales tax is collected at the time of sale. However, if you later bring the boat into Florida and register it here, use tax will apply at the same 6% rate (plus county surtax) with the same $18,000 cap. A credit is given for any sales tax you already paid to another state.
Example A — Nonresident Buyer
$80,000 Boat, Delivered in Broward County
Buyer’s Home State: Georgia (out-of-state)
Boat Removed Within 90 Days? Yes
Documentation Provided? Yes
Total Florida Tax: $0
Nonresident exemption applies. No Florida state or county tax charged.
Example B — Active-Duty Military
$45,000 Boat, Buyer Stationed in Texas
Residency: FL resident, military out-of-state
Certificate of Entitlement Filed
Boat Kept Out of FL ≥6 Months? Yes
Total Florida Tax: $0
Military exemption applies.

What the Calculator Does NOT Include
To keep things accurate, it’s worth knowing what falls outside the sales tax calculation:
Registration and title fees are separate government charges — they are not subject to sales tax.[11] Florida title fees are fixed (around $5.25–$7.75, depending on how you file), and registration fees are based on boat length and range from about $5.50 for the smallest vessels up to $189.75 for the largest.[11]
Dealer documentary fees — the paperwork processing charges that dealers often add — are generally not taxed if they are listed separately on your invoice.[12] If they’re folded into the purchase price, they become taxable.
Some accessories are now permanently exempt (effective August 1, 2025, under Ch. 2025-208 of Florida law): USCG-approved life jackets, portable gas cans of five gallons or less, portable generators up to 10 kW, insect repellent, sunscreen, and tarps under 1,000 square feet.[13] Everything else sold with the boat — electronics, motors, extended warranties — remains taxable at 6% plus surtax.
