Qualification Rules That Decide It
The deduction is regressive in practice: $6,500 of interest on a big loan is real money, but at $135,000 single MAGI the phase-out has already cut the deductible amount, and above $150,000... actually the car phase-out starts at $100,000 single, with $200 knocked off per $1,000 over. This page shows high earners exactly how little survives — an honest no-hype answer for a well-paid audience.
The full rules, caps and phase-outs for every deduction are in one table on the OBBBA rules page.
Worked Example
Arjun financed a US-assembled luxury sedan and pays about $6,500 a year in interest at a $135,000 MAGI.
- • Deductible amount: $0
- • Federal income tax savings: $0 (at the 24% marginal rate)
- • Per biweekly paycheck: $0
That repeats every year of the loan — interest deducts annually, which is why the loan-vs-lease math changed under OBBBA.

Frequently Asked Questions
Why is my luxury car interest deduction smaller than expected?
The car loan phase-out starts at $100,000 MAGI (single) / $200,000 (MFJ), reducing the deduction by $200 per $1,000 over, and interest is capped at $10,000. High-income buyers often retain only a fraction of their interest.
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.
