New Car Buyers Can Cut Interest Costs on Their Loans

Taxpayers who bought a brand‑new car in 2025 may now reduce the amount of interest they pay on their auto loan. The rule comes from a recent law that also dropped taxes on tips and overtime for certain workers and scrapped an electric‑vehicle credit. The new deduction only applies to loans taken after December 31, 2024, and only for vehicles that were fully assembled in the United States. If you bought a used car or a vehicle built abroad, the benefit does not apply. The deduction is limited by income. Single filers with a modified adjusted gross income of $100, 000 or more start to lose the benefit, while married couples begin losing it at $200, 000. Those just under the threshold can still claim a portion of their interest payments. The amount that can be deducted is capped at $10, 000 per year, and the savings depend on your tax bracket; a 22% taxpayer would save about $220 on a $1, 000 interest payment.Unlike most deductions, this one can be taken even if you choose the standard deduction instead of itemizing. That means more people might qualify, though it still won’t affect those who used 0% financing or leased a vehicle. The rule does not replace the former electric‑vehicle tax credit, so buyers of EVs still miss that incentive. Automakers are unlikely to change their production plans because of this small perk. The deduction is narrow—only for U. S. -built cars, not leases—and it offers only a modest financial boost to some buyers. It is more of an added convenience than a major economic driver for domestic manufacturing.
