Overview
Here's the twist that makes boats different from cars: Louisiana exempts genuine private, 'isolated or occasional' boat sales between individuals from the 5% state sales tax entirely, while private car sales get no such break and are taxed exactly like a dealer sale. Buy a used boat from a dealer or as a regular part of someone's business, though, and full state-plus-parish tax applies. The boat trailer itself is a different story again - it's a highway vehicle, so it registers separately with OMV, not LDWF.

Louisiana boat registration FAQ
How much does it cost to register a boat in Louisiana?
For three years: $36 under 16 feet, $57 from 16 to under 26 feet, $78 from 26 to under 40 feet, $99 at 40 feet or longer. First-time buyers add a $26 title fee and, for dealer or business purchases, 5% state tax plus your parish's rate.
Do I really pay 0% tax buying a used boat from a private owner?
Yes, if it's a genuine isolated or occasional sale - one individual selling their own boat, not acting as a dealer. Louisiana's Dept. of Revenue exempts these private watercraft sales from the 5% state tax, a real difference from cars, which owe full tax on private sales with no such carve-out.
What still requires sales tax on a boat purchase?
Buying from a licensed dealer, or from someone selling boats as part of a business, is taxed the normal way - 5% state plus your parish rate - and LDWF wants proof of that payment (Form R-1331) before it will register the boat.
Why did I get a separate title fee for my outboard motor?
Louisiana can title an outboard motor separately from the hull, similar to how it works in some other states. If your purchase includes a titled motor, budget for a second $26 title on top of the boat's own title.
Do kayaks or canoes need to register with LDWF?
Unpowered kayaks, canoes, and paddleboards don't need registration. Add any motor - even a small trolling motor - and registration with LDWF becomes mandatory, same length-based fee schedule as any other powered vessel.
Does my boat trailer register with LDWF too?
No - the trailer is a road vehicle, so it registers with OMV, not LDWF. A boat trailer under 1,500 lbs costs a flat $25 for a four-year term, entirely separate from the boat's own LDWF paperwork and fees.
