Is Auto Loan Interest Tax Deductible in 2026?
Yes. Starting with the 2026 tax year, you can deduct up to $10,000 in interest paid on qualifying vehicle loans. This is a brand-new benefit under the One Big Beautiful Bill Act that applies to both standard deduction and itemized deduction filers.
Here's what you need to know:
Basic requirements:
- Your vehicle must be new and purchased after December 31, 2024
- Final assembly must have occurred in the United States
- The vehicle must be for personal use (not business)
- Gross vehicle weight rating must be under 14,000 pounds
- Your loan must have been taken out after 2024
Income limits: The deduction starts to phase out if your modified adjusted gross income exceeds $100,000 for single filers or $200,000 for married couples filing jointly. Once you hit these thresholds, the deduction decreases gradually.
How the deduction works: If you qualify, you can deduct up to $10,000 in interest per year. If you have multiple car loans, you can combine the eligible interest from each to reach the $10,000 maximum. You don't need to itemize deductions to claim this benefit, which makes it valuable for most people.
Important details: For the 2025 tax year (filed in early 2026), your lender should provide a statement by January 31, 2026, showing total qualified interest paid. You'll need this statement plus your vehicle's VIN to claim the deduction on Schedule 1-A. If your vehicle loan was later refinanced, interest paid on the refinanced amount generally qualifies for the deduction.
Leased or used vehicles don't qualify, and interest included in lease payments is not deductible. This deduction is available for vehicles purchased through December 31, 2028.
Consult a tax professional to confirm your specific eligibility, especially regarding income phase-outs and vehicle requirements. They can help ensure you claim the maximum benefit allowed.
