Texas state tax context
Texas has no state income tax on wages, so this federal deduction is the whole story for Texas residents — there's no state car loan interest tax treatment to layer on top.
How the car loan interest deduction works
The One Big Beautiful Bill Act (OBBBA) created a new above-the-line deduction for interest paid on a loan used to buy a new personal-use vehicle. For tax years 2025 through 2028, you can deduct up to $10,000 of qualified car loan interest per year.
Who qualifies
- The vehicle must be new and for personal use, with final assembly in the United States.
- The loan must originate after December 31, 2024 and be secured by the vehicle.
- The deduction phases out above $100,000 MAGI (single) or $200,000 (married filing jointly).
