For many households, the cost of owning a car is one of the largest monthly expenses — and until now, car loan interest hasn’t been tax-deductible for personal vehicles. That’s about to change.
Under the latest tax reform package, the government is offering a new temporary deduction for interest on car loans. Here's what you need to know about this 2025–2028 opportunity.
What’s Changing?
For tax years 2025 through 2028, individuals can deduct up to $10,000 per year in interest paid on a qualifying car loan — even if they don’t itemize deductions.
This is a first-of-its-kind personal interest deduction, aimed at lowering the cost of car ownership for middle-income families.
Who Qualifies?
To claim the deduction:
The loan must be for a personal-use vehicle
The vehicle must be brand new (original use starts with the taxpayer)
The loan must be a first-lien car loan (not a lease or second mortgage)
The vehicle must be final-assembled in the United States
You must report the VIN on your tax return
Income Phaseout Applies
The deduction phases out as income increases:
Full deduction available up to $100,000 modified AGI (or $200,000 for joint filers)
Reduced by $200 for every $1,000 over the threshold
Completely phased out at $150,000 MAGI (or $250,000 joint)
Example:
If your joint income is $215,000:
You’re $15,000 over the threshold
Your deduction is reduced by $3,000 (15 × $200)
If you paid $6,000 in car loan interest, you could deduct $3,000
Which Vehicles Are Eligible?
An “applicable passenger vehicle” must:
Be used for personal purposes (not business or fleet)
Be a car, SUV, pickup, van, or motorcycle
Weigh under 14,000 pounds
Be manufactured for public road use
Be assembled in the U.S.
Not be salvage or scrap
Leased vehicles do not qualify, nor do commercial or fleet vehicles.
What About Refinancing?
Refinancing is allowed — but only up to the amount of the original loan. The refinanced loan must still be secured by the same vehicle.
How Is the Deduction Claimed?
This deduction is above-the-line, meaning you can take it even if you don’t itemize
You must include the VIN on your return
The lender will be required to issue an information statement, similar to a mortgage interest form, including:
Year, make, and model
Loan origination date
Interest paid during the year
Lenders Must Comply with New Reporting Rules
Auto lenders will be required to:
File new IRS Form 109X (specific number TBD)
Include key loan and vehicle details (VIN, interest, balance, etc.)
Send a copy to borrowers by January 31 each year
When Does It Start?
Applies to loans issued after December 31, 2024
Deduction available for 2025 through 2028
After 2028, the deduction expires unless Congress renews it
This new deduction is a significant step toward easing the financial burden of car ownership, particularly for working families outside of urban transit systems.
It also rewards the purchase of American-assembled vehicles, adding a subtle manufacturing incentive to the tax code.
