Car Loan Interest Deduction 2025: Can You Deduct Your New Car Loan Interest?

Victor • March 4, 2026

For decades, the answer to “Can I deduct car loan interest?” was simple: No.

... But that changed in 2025.


Under the recently passed One Big Beautiful Bill Act, taxpayers may now qualify for a Car Loan Interest Deduction 2025, but the rules are specific, temporary, and not everyone will benefit.


If you're considering buying a new vehicle, here’s what you need to know before assuming you qualify for this new car tax deduction 2025.

What Is the Car Loan Interest Deduction 2025?

The Car Loan Interest Deduction 2025 allows eligible taxpayers to deduct up to $10,000 per year in interest paid on a qualifying personal auto loan.


Important information:

  • It applies to tax years 2025 through 2028
  • It is a deduction that reduces taxable income whether or not you itemize
  • It reduces taxable income, not your tax bill directly
  • The loan must meet strict qualification rules


Even taxpayers taking the standard deduction may benefit.

Who Qualifies for the New Car Tax Deduction 2025?

The rules are stricter than many people expect.

To qualify, the vehicle and loan must meet all of the following:

  • The loan must originate after December 31, 2024
  • The loan must be secured by the vehicle (no personal loans)
  • The vehicle must be new to you (used vehicles generally don’t qualify)
  • The vehicle must be for personal use
  • Final assembly must occur in the United States
  • You must report the Vehicle Identification Number (VIN) on your tax return


Income Limits

The deduction begins to phase out at:

  • Around $100,000 modified adjusted gross income (Single)
  • Around $200,000 (Married Filing Jointly)


Above those levels, the deduction gradually decreases.

Many taxpayers assume they qualify automatically; but income, vehicle eligibility, and loan structure all matter.

This Deduction Is Temporary (2025–2028)

One of the most important planning points:

The Car Loan Interest Deduction 2025 is currently scheduled to run only through 2028.


That creates a limited planning window.


If you’re already considering buying a vehicle during this period, timing and loan structure may affect whether you benefit.


Because the rules are new and fairly specific, many taxpayers are surprised to learn they either partially qualify or don’t qualify at all. Reviewing your situation with a CPA before purchasing can prevent costly assumptions.

What Vehicles Qualify?

Eligible vehicles must be newly purchased, this generally includes passenger vehicles such as cars, SUVs, pickup trucks, and vans that meet U.S. final assembly requirements.


Leases do not qualify, and used vehicles typically do not qualify.



This is not a blanket deduction for any car purchase.

Common Questions

Can I deduct car loan interest if I refinance?

Generally, the original loan must meet qualification rules. Refinancing situations may require careful review.


Can I deduct interest on a used car?

Typically no, the vehicle must be new and meet eligibility criteria.


Is this better than leasing?

Leases do not qualify for this interest deduction. However, business lease treatment follows separate rules.

Final Thoughts: Before Buying, Run the Numbers

The Car Loan Interest Deduction 2025 is real and it can provide meaningful tax relief. But it is temporary, and highly specific.

Before buying a new vehicle expecting a tax break, make sure the numbers actually work in your favor, especially if you are:

  • Near the income phase out thresholds
  • A small business owner
  • Considering partial business use
  • Living in California


A short planning conversation can help you avoid surprises and potentially structure the purchase more efficiently.
