Qualification Rules That Decide It
Mainstream three-row SUVs are mostly US-assembled — Explorer (Chicago), Grand Cherokee (Detroit), Telluride (Georgia) — making this the highest-volume qualifying category. The phase-out's $200,000 MFJ line means two-income families almost always deduct the full interest. A second qualifying vehicle's loan stacks: the cap is per-taxpayer on total interest, $10,000 across all qualifying loans.
The full rules, caps and phase-outs for every deduction are in one table on the OBBBA rules page.
Worked Example
Beth financed a Chicago-built Explorer and pays about $2,900 a year in interest.
- • Deductible amount: $2,900
- • Federal income tax savings: $348 (at the 12% marginal rate)
- • Per biweekly paycheck: $13
That repeats every year of the loan — interest deducts annually, which is why the loan-vs-lease math changed under OBBBA.

Frequently Asked Questions
Can I deduct interest on two qualifying vehicles?
Yes, but the $10,000 cap applies to your combined qualifying loan interest for the year, and the phase-out tests your total MAGI. Two car loans' interest sums before the 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.
