How does the Auto Loan Interest Deduction Work?
Under the federal tax law (H.R. 1), eligible buyers may deduct up to $10,000 per tax year in interest paid on a qualifying auto loan
for a new personal vehicle that was final-assembled in the United States.
Who Is Eligible?
To qualify for this federal tax benefit, you must meet these criteria:
- The vehicle must be purchased new (not leased or used).
- The loan must be incurred after December 31, 2024 and secured by a lien on the vehicle.
- The vehicle must be for personal use (no business/fleet purchases).
- You must include the vehicle's VIN on your tax return to claim the deduction.
- If a qualifying auto loan is refinanced, the deductible interest generally still qualifies.
- Under IRS rules, the deduction is an above-the-line deduction, so you can claim it even if you don't itemize your tax return.
Which Vehicles May Qualify?
Qualifying Vehicles Must:
- Be a car, minivan, van, SUV, pickup truck, or motorcycle.
- Have a gross vehicle weight rating (GVWR) of less than 14,000 lbs.
- Have undergone final assembly in the United States.
- Used vehicles and leased vehicles do NOT qualify for this deduction.
🚩 Final assembly in the United States is the key requirement - even some foreign-brand vehicles assembled here may qualify.
Verify final assembly by checking the VIN with the official NHTSA VIN Decoder, and consult your tax advisor for guidance.
