Qualification Rules That Decide It
The OBBBA traded the $7,500 EV purchase credit for a build-eligible fleet rule, which makes the interest deduction the surviving tax angle for many Tesla buyers — interest deducts every year of the loan instead of a one-time credit. Tesla's US assembly covers the qualifying-vehicle side; your side of the test is income under $100,000 (single) before the $10,000-capped interest starts stepping down.
The full rules, caps and phase-outs for every deduction are in one table on the OBBBA rules page.
Worked Example
Wei financed a US-built Model 3 and pays about $3,400 a year in loan interest.
- • Deductible amount: $3,400
- • Federal income tax savings: $748 (at the 22% marginal rate)
- • Per biweekly paycheck: $29
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 a Tesla qualify for the OBBBA loan interest deduction?
Yes — Model 3 and Model Y assembled in the US are qualifying vehicles. Your loan interest up to $10,000 is deductible if the loan was signed after the law's effective date and your MAGI stays under the phase-out ($100,000 single / $200,000 MFJ).
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.
