Main developments

Federal new‑car loan interest deduction

A change in U.S. federal tax law now allows taxpayers to deduct up to $10,000 per year in interest on a new car loan. The deduction applies where both the vehicle and the loan meet specific requirements under the new rule; buyers in 2025 and 2026 can potentially benefit. As an example provided under the new framework, financing a $35,000 new car and paying $2,800 in interest in 2025 would be eligible to consider under the revised treatment of loan interest. Credit unions and lenders, such as Scenic Community Credit Union, are highlighting member support for taking advantage of the new filing and loan features.

Section 179 deduction increase

The One Big Beautiful Bill, signed on 4 July 2025, substantially increased the Section 179 deduction limit. The cap rose from $1,160,000 to $2,500,000, expanding the amount businesses can deduct for qualifying property, including many vehicles on the 2025–2026 Section 179 vehicle list.
