Overview
One genuinely distinct Kentucky quirk: while car registrations expire in your birth month, every boat registration in the state expires on the same date - April 30 - regardless of when you bought or last renewed it. As of April 2026, Kentucky finally launched online boat registration renewal statewide, so you no longer have to visit the clerk's office in person every spring. And like vehicles, boats owe an annual property tax assessed each January 1, billed with that April renewal.

Kentucky boat registration FAQ
How much does it cost to register a boat in Kentucky?
$25 to $40 a year depending on length, plus a $9 title fee the first time and 6% usage tax on the purchase price or the boat's NADA retail value, whichever is higher. There's also an annual property tax, assessed the same way as vehicles.
Why do all Kentucky boats expire the same day?
Unlike vehicle registration, which follows your birth month, Kentucky standardized boat registration to a single statewide expiration of April 30 every year - regardless of when you first registered. It simplifies enforcement for a much smaller registration pool than passenger vehicles.
Can I renew my Kentucky boat registration online?
Yes, as of April 2026 - Kentucky launched an online renewal option so boat owners no longer need an in-person visit every spring. You'll need your KY boat number and title number; the boat's property tax is due at the same time.
Do canoes and kayaks need to be registered in Kentucky?
Unpowered, non-sail vessels like canoes and kayaks generally don't need registration. Any motorized vessel - including a canoe with a trolling motor - does, through the same county clerk process as a larger boat.
Is there a separate title fee for the boat's outboard motor?
No - unlike some states that title outboard motors separately from the hull, Kentucky titles the boat as a unit; the motor typically doesn't require its own separate title.
Does my boat trailer register separately?
Yes - the trailer is a vehicle in its own right and registers with your county clerk on the standard passenger/utility trailer schedule, separate from the boat's own registration and property tax.
