The Trailer Line
The OBBBA provision covers motor vehicles — cars, trucks, motorcycles. Unpowered trailers don't create qualifying loans; the boat itself may touch the second-home interest rule if it has sleeping/cooking/toilet facilities.
- • Tow vehicle loan → OBBBA interest deduction
- • Boat trailer loan → no
- • Boat loan → possible second-home interest treatment (separate track)
Worked Example
MFJ household, $3,100 of interest on the tow vehicle.
- • Deduction $3,100; $372 at 12%

Frequently Asked Questions
Can I deduct boat trailer loan interest under the OBBBA?
No — trailers aren't motor vehicles for this deduction. Your tow vehicle's loan interest does deduct.
What about the boat loan?
Boats with sleeping, cooking, and toilet facilities may qualify for second-home mortgage-interest treatment — a different provision entirely.
