2025 Car Loan Tax Deduction: Who Qualifies & How Much You’ll Save

For the 2025 tax year, eligible U.S. Taxpayers can deduct up to $10,000 in auto loan interest under a temporary provision of President Donald Trump’s One Big Beautiful Bill Act. Although, the actual tax savings for most borrowers will likely be far less than that headline figure.

While a $10,000 deduction sounds substantial, it doesn’t translate to a $10,000 reduction in taxes owed. The deduction reduces taxable income, not taxes dollar-for-dollar. Most auto loans don’t accrue $10,000 in interest annually. According to Cox Automotive, a typical 72-month new car loan at 9.5% interest on a $48,000 vehicle generates around $3,800 in interest in the first year.

Even with that amount, the actual tax savings, assuming a 15-20% tax rate, would be less than $750 in the first year. It would require a loan of approximately $112,000 to generate $10,000 in deductible interest in a single year.

The auto loan interest deduction, enacted July 4, 2025, as part of the One Big Beautiful Bill Act, applies only to loans meeting specific criteria:

• The loan originated after December 31, 2024, and is secured by the vehicle.
• The vehicle is new – used vehicle loans do not qualify.
• The vehicle is for personal, not business, use.
• Eligible vehicles include cars, minivans, vans, SUVs, pickup trucks, and motorcycles with a gross vehicle weight rating under 14,000 pounds.
• The vehicle must have undergone final assembly in the United States.

The $10,000 maximum deduction phases out for higher earners. Single filers notice the deduction reduced if their modified adjusted gross income is between $100,000 and $150,000. For married couples filing jointly, the phaseout range is $200,000 to $250,000.

Importantly, taxpayers can claim the deduction whether they itemize or take the standard deduction.

The deduction is claimed on Schedule 1-A of Form 1040. Tax software will typically complete this automatically. Taxpayers must include the vehicle identification number (VIN) on their tax return. The VIN can be found on the driver’s side dashboard or vehicle documentation.

The National Highway Traffic Safety Administration’s VIN Decoder can be used to verify the vehicle’s final assembly location.

Borrowers should receive a statement from their lender detailing the total interest paid on the qualifying loan.

Industry experts are skeptical. Jeremy Robb, chief economist at Cox Automotive, stated that the tax credit is limited and won’t significantly impact the affordability challenges or high interest rates currently facing the automotive market.

What tax years does this deduction apply to?

The deduction applies to tax years 2025 through 2028.

Does this deduction apply to electric vehicles?

Yes, as long as the vehicle meets all other eligibility requirements, including final assembly in the United States.

What if my income is close to the phaseout threshold?

The deduction is reduced proportionally within the phaseout range. Consult the IRS guidelines or a tax professional for specific calculations.

Pro Tip: Maintain accurate records of your auto loan interest payments and the vehicle’s VIN to ensure a smooth tax filing process.
