What You Need to Know About Trump’s Car Loan Interest Deduction

Congress passed a new tax law as part of the "One Big Beautiful Bill Act," signed by President Trump on July 4, 2025. This law lets people deduct up to $10,000 per year in car loan interest paid on qualifying auto loans.

The benefit applies to loans taken out from January 1, 2025 through December 31, 2028, on new, personally owned vehicles assembled in the United States. Used cars and leases do not qualify.
 

The Catch: Who Really Benefits?

A $10,000 deduction sounds appealing, but most buyers won’t receive that much. Getting the full $10,000 deduction would require a car loan of about $112,000 or more, which is far above the national average.

Only about 1% of car loans reach that amount, meaning very few people will qualify for the largest benefit.
 

What Most People Can Actually Save

The average new car loan in 2025 is about $43,000. For such a loan, you might pay around $3,000 in interest during the first year—the maximum you could deduct in that year.

This deducts from your taxable income, not directly from your tax bill. For most people, the actual savings in the first year are about $500 or less, depending on their tax bracket.

Over a typical six-year loan, buyers might deduct several thousand dollars, saving a few hundred dollars per year. It’s a helpful benefit, but not life-changing.
 

Income Limits

There are income restrictions: the deduction starts reducing if you earn over $100,000 ($200,000 for married couples) and is completely phased out for incomes above $150,000 ($250,000 for couples).

So, people who can afford the most expensive cars likely won’t qualify, and most families won't spend enough on cars to get the highest benefit.
 

Vehicle Requirements

Only new cars assembled in the U.S., weighing less than 14,000 pounds and bought for personal use, are eligible. Used cars, leases, and vehicles assembled outside the United States do not qualify.
 

Who Gets the Most Benefit?

The biggest winners could be people who buy high-end luxury cars and have just the right income to qualify—but that’s a very small group. The requirement for U.S. assembly further limits choices, especially among luxury brands.
 

Should You Change How You Buy a Car?

While any tax break is helpful, this one shouldn’t change your car-buying decisions. It’s a nice perk, but not worth stretching your budget on a more expensive car.
 

Smart Tips for Buying a Car

 

• Buy a car that fits your needs and budget.
• Shop for the best loan rates.
• Negotiate for a better price.
• Consider used or certified pre-owned cars if value is your goal (note used cars do not qualify for this deduction).
• Before buying, calculate how much you’d actually save with the tax break. Most people will see modest savings—not enough to make a much more expensive car affordable.

 

Law Status

This deduction is part of a law already enacted and applies only to new purchases between 2025 and 2028. Always make financial decisions based on your personal situation, not just headlines.
 

Bottom line

The new tax deduction offers modest help for average buyers, with most of the benefit going to those purchasing expensive, U.S.-assembled new vehicles with qualifying incomes.

The smartest car-buying strategy is still to buy responsibly and within your means.
