The “one big, beautiful bill” was signed into law by President Donald Trump last week, with a gain for some car buyers and a loss for others.
Consumers could now benefit from tax deductions on auto loans, but electric vehicle buyers will lose the savings vided by EV tax credits.
Auto loan interest now tax-deductible for some borrowersCar buyers who finance will be able to deduct up to $10,000 a year for car loan interest they pay.
The deduction is “above-the-line,” meaning it will apply to people who claim the standard deduction and those who itemize.

The intent of the auto loan interest deduction is to make cars more affordable for buyers, given that average car prices and interest rates remain high.
But the benefit for some car buyers will be limited.
In fact, a person would need to get an auto loan of more than $110,000 to benefit from the maximum deduction, according to Cox Automotive Chief Economist Jonathan Smoke.
For context, the average new vehicle transaction price is $49,000. Most vehicles priced at $110,000 or above would be luxury sedans or sports cars, and only 1% of all auto loans are of that size.
“The typical new loan really would only see around $500 benefit, and that’s in year one and then declining over time,” Smoke said at the Cox Automotive 2025 Mid-Year Review on June 25.
Average monthly car payments are around $750, and a record one in five new car buyers committed to $1,000+ payments in the second quarter of 2025, according to Edmunds.
So, for most borrowers, the annual savings in loan interest would be less than their monthly car payment. The auto loan interest deduction is also temporary — effective for tax years 2025 through 2028.

Car buyers planning to take advantage of EV tax credits should do so sooner than later.
In addition to grabbing the credit before it is gone, car shoppers may find more EV incentives at dealerships wanting to move inventory.
Auto industry groups had pushed for more time to mote EV sales before the tax credit ends, but their attempts were unsuccessful.
