Can I Deduct Interest on a Business Vehicle Loan?

Short answer: Yes, self-employed people can deduct the business-use share of auto loan interest, even with the standard mileage rate.

W-2 employees can't. For personal cars, the separate 2025-2028 car loan interest deduction may apply.

Records to keep: Keep a contemporaneous mileage log (date, miles, business purpose), business-use percentage, the purchase contract, and a photo of the door-jamb GVWR sticker.
