Qualification Rules That Decide It
Verify the assembly plant on your specific trim — most Silverado 1500s are US-built, which is the qualifying test. Trades count differently than people assume: interest on the new loan qualifies from day one, but negative equity rolled into the loan is still part of the vehicle-secured loan and its interest qualifies too, since the collateral test is what governs.
The full rules, caps and phase-outs for every deduction are in one table on the OBBBA rules page.
Worked Example
Jed financed a Fort Wayne-built Silverado 1500 at about $2,500 a year in interest.
- • Deductible amount: $2,500
- • Federal income tax savings: $550 (at the 22% marginal rate)
- • Per biweekly paycheck: $21
That repeats every year of the loan — interest deducts annually, which is why the loan-vs-lease math changed under OBBBA.

Frequently Asked Questions
Does rolled-in negative equity from my trade count?
The loan as a whole is secured by the qualifying vehicle, so interest on the full balance — including rolled-in negative equity — counts toward the deduction, up to the $10,000 annual interest cap.
Do I need to itemize deductions to claim the car loan interest deduction?
No. Like the other OBBBA deductions, vehicle loan interest is an above-the-line adjustment on Schedule 1-A — it stacks on top of the standard deduction.
