This bill proposes to amend the Internal Revenue Code of 1986, specifically Section 163(h)(4)(D), to broaden the scope of vehicles for which loan interest payments are tax deductible. The primary goal is to allow taxpayers to deduct interest paid on loans for a wider array of personal vehicles. The legislation redefines "qualified passenger vehicles" to include not only traditional cars, minivans, vans, sport utility vehicles, pickup trucks, and motorcycles under 14,000 pounds, but also vehicles with at least two wheels. Crucially, it expands the definition to encompass recreational vehicles such as trailers, campers, or other vehicles designed for temporary living quarters for recreational, camping, or seasonal use. These amendments are set to apply to any indebtedness incurred after December 31, 2025.
