Buying a boat in Georgia involves more than just the sticker price. Before you sign anything, you should know about three separate layers of cost: sales or use tax, annual property tax, and registration fees. This guide walks you through how each one is calculated — in plain English, with real dollar-and-cents examples — so you know exactly what to expect.
The calculations in Georgia’s Boat Tax Calculator are built on official Georgia Department of Revenue (DOR) and Department of Natural Resources (DNR) rules. Every formula cited here comes from authoritative sources, which are listed in full at the bottom of this page.
Step 1: Sales Tax (or Use Tax)
If you buy a boat from a dealer in Georgia, you owe Georgia sales tax. The state charges a flat 4% state rate, plus your county or city adds its own local surtax — typically between 2% and 5%, making the total anywhere from 6% to 9% depending on where you are. For example, Cherokee County sits at 6% total, while Columbus (Muscogee County) reaches 9%.
The tax is applied to the taxable purchase price. If you buy from a dealer and trade in an old boat, Georgia law lets you subtract the trade-in value before calculating tax — so you only pay tax on the difference. This trade-in deduction does not apply to private sales.
If you buy from a private individual (a “casual sale”), Georgia exempts the transaction entirely from sales tax. No tax is due at the time of purchase.
If you buy a boat out of state and bring it to Georgia, you owe Georgia use tax at the same combined rate. However, any sales tax you already paid to the other state is credited against what Georgia charges, so you never pay double on the same dollars.
Quick Reference — Sales Tax Rates (2026) State base rate: 4.0% | Typical local surtax: 2–5% | Combined range: 6–9%
Private (casual) sales: fully exempt from sales tax.
Example A — New dealer purchase in Forsyth County
Example 1
You buy a brand-new 2026 pontoon boat for $50,000 from a dealer in Forsyth County. No trade-in. Forsyth County’s total tax rate is 7% (4% state + 3% local).
State tax portion: $50,000 × 4% = $2,000
Local tax portion: $50,000 × 3% = $1,500
Total Sales Tax Due: $3,500
Example B — Dealer purchase with a trade-in in Cherokee County
Example 2
You buy a used boat from a Cherokee County dealer for $30,000 and trade in your old boat, valued at $8,000. Cherokee County’s total rate is 6%.
Taxable amount: $30,000 − $8,000 = $22,000
Sales tax: $22,000 × 6% = $1,320
Total Sales Tax Due: $1,320 (you saved $480 thanks to the trade-in deduction)
Step 2: Out-of-State Use Tax Credit
If you bought your boat in another state and paid sales tax there, Georgia doesn’t make you pay the full tax again. Instead, Georgia charges its rate, then subtracts whatever you already paid elsewhere. The formula is simple: take what Georgia would charge, subtract what you paid out of state, and the result is what you still owe Georgia. If the out-of-state tax was equal to or greater than Georgia’s, you owe nothing more.
Example A — Boat bought in Florida, brought to Muscogee County
Example 1
You purchase an $80,000 boat in Florida, paying Florida’s 6% sales tax: $4,800. You move to Columbus, Georgia (Muscogee County, total rate 9%).
Georgia tax would be: $80,000 × 9% = $7,200
Credit for Florida tax paid: −$4,800
Georgia Use Tax Still Owed: $2,400
Example B — Boat bought in Tennessee, brought to Forsyth County
Example 2
You buy a $40,000 boat in Tennessee, paying Tennessee’s 7% tax: $2,800. You register in Forsyth County (7% combined).
Georgia use tax would be: $40,000 × 7% = $2,800
Credit for Tennessee tax paid: −$2,800
Georgia Use Tax Still Owed: $0 — your credit covers the full amount
Step 3: Annual Property Tax (Ad Valorem)
Unlike a car, a boat in Georgia is not subject to the Title Ad Valorem Tax (TAVT) that you may have heard about. Instead, boats are taxed as personal property every single year. The person who owns the boat on January 1 of any given year is responsible for that full year’s property tax, regardless of when they sell it.
Here is how the calculation works in three steps:
1. Determine Fair Market Value (FMV). This is typically the purchase price for a new boat, or a NADA/BUC guide value for older boats. Owners declare their boat’s FMV on Georgia DOR Form PT-50M, the Marine Personal Property Tax Return, filed with their county tax assessor.
2. Apply the 40% assessment ratio. Georgia only taxes 40% of your boat’s fair market value, not the full amount. So if your boat is worth $50,000, only $20,000 is the “assessed value” that gets taxed.
3. Apply your county’s millage rate. Each county sets a millage rate — the number of dollars charged per $1,000 of assessed value. A rate of 30 mills means $30 per $1,000 of assessed value. You multiply your assessed value by this rate to get your annual tax bill.
The $20,000 Personal Property Exemption (2026) Georgia’s Referendum A raised the personal property exemption to $20,000. If your boat’s fair market value — combined with any other personal property you own — totals $20,000 or less, you owe zero property tax on it. This is a meaningful break for owners of smaller or older boats.
Example A — New $50,000 powerboat in Forsyth County
Example 1
Your new boat has a fair market value of $50,000. You have no other personal property. Forsyth County’s millage rate is approximately 28 mills.
Assessed value: $50,000 × 40% = $20,000
Annual tax: ($20,000 ÷ 1,000) × 28 = $560
Annual Property Tax: $560 per year
Example B — Older $18,000 boat — exemption applies
Example 2
You own a 2013 used boat with a fair market value of $18,000. You have no other personal property reported.
Total personal property value: $18,000 — below the $20,000 exemption threshold
Annual Property Tax: $0 — fully exempt
Step 4: Estimating Fair Market Value by Age
If you don’t have a NADA guide value handy, the calculator uses a standard depreciation schedule based on your boat’s model year to estimate fair market value. New boats lose value quickly in the first few years, then taper off. Here is how the schedule works:
A brand-new boat (age 0) is worth 100% of its purchase price. After one year, it’s worth roughly 85%. After two years, 75%. By year five, about 57%. From years 6 through 10, the value drops an additional 3 percentage points per year. Boats 11 years old or older are treated as retaining 42% of their original purchase price as fair market value.
Example A — 3-year-old boat purchased for $60,000
Example 1
You bought a boat in 2023 for $60,000. It is now 2026 — 3 years old. The depreciation factor for year 3 is 68%.
Estimated FMV: $60,000 × 0.68 = $40,800
Estimated Fair Market Value for Tax Purposes: $40,800
Example B — 8-year-old boat purchased for $45,000
Example 2
Your boat was purchased in 2018 for $45,000. In 2026 it is 8 years old. For year 8, the factor is 0.57 − (3 × 0.03) = 0.48.
Estimated FMV: $45,000 × 0.48 = $21,600
Estimated Fair Market Value for Tax Purposes: $21,600
Step 5: Registration Fees
Every boat in Georgia must be registered with the Georgia Department of Natural Resources (DNR). Registration lasts three years and the fee depends entirely on your boat’s length. There is also a small transaction fee added on top. If you want a paper title instead of a free electronic one, there is a $10 fee for that as well.
Boats under 16 feet pay the lowest base fee; those 40 feet and over pay the highest. Here are the 2026 rates from the DNR:
Under 16 feet: $25 base fee + $10 transaction fee = $35 total. Between 16 and 26 feet: $60 + $10 = $70 total. Between 26 and 40 feet: $130 + $10 = $140 total. 40 feet or longer: $200 + $10 = $210 total.
Example A — 22-foot pontoon boat
Example 1
Your pontoon is 22 feet long, placing it in the 16–26 foot bracket.
Base registration fee: $60
Transaction fee: $10
3-Year Registration Fee: $70
Example B — 42-foot yacht
Example 2
Your vessel is 42 feet long, in the 40-feet-and-over bracket.
Base registration fee: $200
Transaction fee: $10
3-Year Registration Fee: $210
Putting It All Together — A Complete Example
Here is what a full calculation looks like for a typical Georgia buyer in 2026. Suppose you purchase a new 22-foot powerboat from a Forsyth County dealer for $50,000, with no trade-in. The boat was built in 2026. You have no other personal property and you are a Georgia resident. Forsyth County’s total sales tax rate is 7% and its millage rate is approximately 28.
Sales tax: $50,000 × 7% = $3,500, due at purchase.
Registration: 22-foot boat = $70 (three-year fee).
Property tax (year 1): FMV = $50,000 × 85% (one year old by Jan 1) = $42,500. Assessed value = $42,500 × 40% = $17,000. Since $17,000 is below the $20,000 exemption threshold, property tax = $0 for year 1.
Property tax (year 2): FMV = $50,000 × 75% = $37,500. Assessed value = $15,000. Still below $20,000 — property tax = $0.
Property tax (year 3): FMV = $50,000 × 68% = $34,000. Assessed value = $13,600. Still below $20,000 — property tax = $0.
In this case, your upfront cost is $3,570 ($3,500 tax + $70 registration), and for the first three years your annual property tax bill would be zero thanks to the exemption.
Important Rules to Keep in Mind
January 1 ownership matters. Georgia property tax is assessed to whoever owns the boat on January 1 each year. If you sell your boat on January 2, you are still on the hook for the entire year’s property tax bill.
Boats are not subject to TAVT. Georgia’s Title Ad Valorem Tax applies to cars and trucks — not to recreational boats. Boats are taxed as personal property under a separate system.
Late penalties are steep. If you miss your property tax due date, Georgia charges a 10% penalty. Interest also accrues monthly at roughly Prime + 3%, which in 2026 works out to around 10–11% annually.
Where the boat is kept determines the county. Georgia law (O.C.G.A. §48-5-16) says the boat is taxed in whichever county it is “functionally located” — meaning where it spends at least 184 days a year. If you keep your boat at a marina in a different county from your home, the marina’s county may be the right one to file in.
