Everything you need to know about sales tax, registration fees, and title costs — explained in plain English, with real dollar examples.
How the Calculator Works
Buying a boat in Texas involves more than just the purchase price. You’ll owe the state a sales or use tax, a title fee, and annual registration — and the exact amounts depend on where you live, what type of boat you’re buying, and how you’re buying it. This guide walks you through every step the calculator uses to arrive at your final number.
The good news: for most Texans buying a typical motorboat or sailboat under 115 feet, the math is straightforward. There is a single flat state tax rate, a fixed title fee, and a registration fee based on the length of your boat. No surprises.
The core formula: (Sale Price − Trade-In Value) × Tax Rate + Title Fee + Registration Fee = Your Total Due
Step 1 — Sales Tax on Your Boat
Texas imposes a 6.25% sales tax on the retail sale of any boat or outboard motor 115 feet long or shorter. This is governed by Texas Tax Code Section 160.021. Importantly, no city or county tax is added on top — what the state charges is all you pay on the taxable amount.[1]
The tax is calculated on the net sale price — that is, the agreed purchase price minus the value of any boat or motor you trade in. If you trade in a boat worth $10,000 on a $60,000 purchase, you’re only taxed on $50,000.[2]
There is also a tax cap of $18,750 per sale, set by Texas Tax Code Section 160.026. This means no matter how expensive your boat is, you’ll never owe more than $18,750 in state boat sales tax.[3] (The cap kicks in on boats priced above $300,000, since 6.25% × $300,000 = $18,750.)
Example A — Mid-range boat with a trade-in
Example 1 of 2
A $80,000 boat with a $15,000 trade-in, bought in San Antonio
| Purchase price | $80,000 |
| Trade-in value (deducted) | − $15,000 |
| Taxable amount | $65,000 |
| State tax rate | × 6.25% |
| Sales tax owed | $4,062.50 |
The $18,750 cap doesn’t apply here — the tax is well under it. No local tax is added for boats under 115 ft.
Example B — High-value boat hitting the cap
Example 2 of 2
A $500,000 boat with no trade-in, bought in Houston
| Purchase price | $500,000 |
| Trade-in value | $0 |
| Calculated tax (6.25%) | $31,250 |
| Tax cap (Section 160.026) | $18,750 max |
| Sales tax owed | $18,750 |
Even though 6.25% of $500,000 is $31,250, the law caps boat sales tax at $18,750. You save $12,500 on this purchase.
Step 2 — Use Tax (Out-of-State Purchases)
If you’re a Texas resident and you buy a boat in another state — then bring it to Texas — you don’t escape the tax. Instead, you’ll owe a use tax of 6.25% under Texas Tax Code Section 160.022. The use tax applies within 45 working days of bringing the boat into the state.[4]
The good news: if you already paid a sales tax in the state where you bought it, Texas gives you a dollar-for-dollar credit for that amount under Section 160.025. So if you paid 5% sales tax in another state, you’d only owe Texas the remaining 1.25%.[5]
Note: Unlike the sales tax described in Step 1, the use tax does not have the $18,750 cap. The full 6.25% applies regardless of price.
Example A — Buying in a no-sales-tax state
Example 1 of 2
Texas resident buys a $40,000 boat in Montana (no sales tax), brings it home
| Purchase price | $40,000 |
| Tax paid in Montana | $0 |
| Texas use tax (6.25%) | $2,500 |
| Use tax owed to Texas | $2,500 |
Example B — Buying in a state with its own sales tax
Example 2 of 2
Texas resident buys a $60,000 boat in Florida (6% sales tax already paid)
| Purchase price | $60,000 |
| Tax paid to Florida (6%) | $3,600 |
| Texas use tax (6.25%) | $3,750 |
| Credit for Florida tax | − $3,600 |
| Use tax owed to Texas | $150 |
Step 3 — New Texas Residents
Moving to Texas and bringing your boat with you? You get a significant break. Under Texas Tax Code Section 160.023, new Texas residents pay a flat $15 tax per boat or motor — regardless of what the vessel is worth.[6] This replaces the 6.25% use tax entirely.
You’ll need to provide proof that you’ve genuinely relocated — things like a new Texas driver’s license, a deed or lease on a Texas home, or utility bills. The $15 applies per item, so a boat plus a separate outboard motor would be $30 total.
Example A — New resident with a modest boat
Example 1 of 2
Family relocates from Ohio with a $25,000 ski boat
| Boat value | $25,000 |
| Standard use tax (6.25%) | would be $1,562.50 |
| New resident flat tax instead | $15 |
| Tax owed | $15 |
Savings vs. use tax: $1,547.50
Example B — New resident with a high-value boat
Example 2 of 2
Professional relocating from California with a $200,000 sailboat
| Boat value | $200,000 |
| Standard use tax (6.25%) | would be $12,500 |
| New resident flat tax instead | $15 |
| Tax owed | $15 |
Savings vs. use tax: $12,485. This is one of the most generous provisions in Texas boat tax law.
Step 4 — Boats Over 115 Feet
Very large vessels — those exceeding 115 feet — are taxed differently. Rather than the special boat sales tax regime, they fall under Texas’s limited sales and use tax, which means both the state rate and local rates apply.[7] The combined rate is 6.25% state + up to 2% local, for a maximum of 8.25% depending on where the sale takes place. There is no $18,750 cap for these vessels.
Local tax rates are determined by the city, county, transit authority, and special districts where the sale occurs. The Texas Comptroller maintains an online Sales Tax Rate Locator where you can find the exact combined rate for any address in Texas.[8]
Example A — Large yacht in Dallas
Example 1 of 2
A 120-foot yacht priced at $800,000, sold in Dallas (2% local rate)
| Purchase price | $800,000 |
| State tax (6.25%) | $50,000 |
| Local tax (2% — Dallas city + MTA) | $16,000 |
| Total tax owed | $66,000 |
Example B — Large vessel in a lower-tax area
Example 2 of 2
A 130-foot vessel at $1,200,000 in a county with only 1.5% local rate
| Purchase price | $1,200,000 |
| State tax (6.25%) | $75,000 |
| Local tax (1.5%) | $18,000 |
| Total tax owed | $93,000 |
Step 5 — Boat Trailers
Boat trailers are legally classified as motor vehicles in Texas — not as boats — which means they are taxed under the standard motor vehicle sales tax rules rather than the boat-specific Chapter 160 rules.[9] The rate is 6.25% state + up to 2% local. Texas requires the trailer to be invoiced separately from the boat at the time of sale.
So if you’re buying a boat-and-trailer package, the calculator splits the transaction: the boat portion uses boat tax rules, and the trailer portion uses motor vehicle rules. In most parts of Texas, both end up at the same combined rate — but the distinction matters legally, and it keeps your documentation clean for TPWD.
Example A — Trailer bought alongside a boat
Example 1 of 2
$8,000 trailer purchased in Austin (2% local rate)
| Trailer price (separate invoice) | $8,000 |
| State tax (6.25%) | $500 |
| Local tax (2% — Austin city + MTA) | $160 |
| Trailer tax owed | $660 |
Example B — Trailer only, rural county
Example 2 of 2
$5,500 trailer in a rural county with 0.5% local rate
| Trailer price | $5,500 |
| State tax (6.25%) | $343.75 |
| Local tax (0.5%) | $27.50 |
| Trailer tax owed | $371.25 |
Step 6 — Registration & Title Fees
In addition to any tax, every boat in Texas requires a title and annual registration through the Texas Parks and Wildlife Department (TPWD). The fees are set by 31 TAC Section 53.16 and don’t vary by location — they’re the same whether you’re in Amarillo or South Padre Island.[10]
Registration fees are based on the boat’s length:
- Under 16 feet (Class A): $32/year
- 16 to 26 feet (Class 1): $53/year
- 26 to 40 feet (Class 2): $110/year
- 40 feet or more (Class 3): $150/year
Title fee is a flat $27. A transfer of ownership card costs $11. Bonded titles (when prior ownership can’t be proven) cost $37.
Example A — 22-foot motorboat, new purchase
Example 1 of 2
First-time title and registration on a 22-foot bass boat
| Title fee | $27 |
| Registration (Class 1, 16–26 ft) | $53 |
| Ownership transfer card | $11 |
| Total TPWD fees | $91 |
Example B — 45-foot cruiser, new purchase
Example 2 of 2
Title and registration on a 45-foot cabin cruiser
| Title fee | $27 |
| Registration (Class 3, 40 ft+) | $150 |
| Ownership transfer card | $11 |
| Total TPWD fees | $188 |
Step 7 — Exemptions & Credits
Several groups are exempt from Texas boat sales and use tax under Texas Tax Code Section 160.024:[11]
- Federal government agencies
- Texas state agencies
- Texas cities, counties, and political subdivisions
- Authorized volunteer fire departments
There is also a nonresident temporary use permit option for out-of-state visitors. Instead of paying the full 6.25% use tax, a nonresident can purchase a 90-day permit for $150 under Texas Tax Code Section 160.0246–160.0247. The boat must leave Texas within those 90 days. A maximum of two permits per vessel per year are allowed.[12]
Example A — Nonresident visiting Texas waters
Example 1 of 2
Louisiana resident brings $45,000 boat to Texas for a 2-month fishing trip
| What they’d owe in use tax (6.25%) | $2,812.50 |
| 90-day temporary use permit instead | $150 |
| Actual amount owed | $150 |
The boat must leave Texas within 90 days of the permit date.
Example B — Government agency purchase
Example 2 of 2
A Texas county sheriff’s department buys a $70,000 patrol boat
| Purchase price | $70,000 |
| Tax rate (6.25%) | would be $4,375 |
| Government exemption applied | − $4,375 |
| Tax owed | $0 |
Standard TPWD registration and title fees still apply.
Step 8 — Late Penalties
If you don’t pay your boat taxes on time, Texas charges penalties under Texas Tax Code Section 111.102.[13] Private buyers have 45 working days from the date of purchase (or first use in Texas) to pay. After that:
- 1–30 days late: 5% penalty on top of the tax owed
- More than 30 days late: 10% penalty
- After 60 days: Interest also begins accruing at the state rate
Example A — Slightly late payment
Example 1 of 2
$3,000 in tax owed, paid 20 days after the deadline
| Tax owed | $3,000 |
| Late penalty (5%) | $150 |
| Total due | $3,150 |
Example B — Significantly late payment
Example 2 of 2
$5,000 in tax owed, paid 45 days after the deadline (plus interest accruing)
| Tax owed | $5,000 |
| Late penalty (10%) | $500 |
| Interest (day 61+, estimate) | ~$30–$60 |
| Approximate total due | ~$5,560 |
Interest is calculated at the state-published rate on the unpaid balance from day 61 until you pay. The exact amount depends on the current rate.

The Texas Boat Tax Calculator takes all of the above rules — tax rate, trade-in deductions, the $18,750 cap, residency status, boat length, vessel type, and applicable fees — and applies them automatically based on what you enter. The goal is to give you a clear, itemized total before you ever sign a purchase agreement.
When in doubt, always confirm your figures with the Texas Comptroller of Public Accounts or a licensed Texas tax professional. Tax laws can change, local rates are updated quarterly, and individual circumstances vary.
