## What’s new under the law Signed into law in July 2025, the **One, Big, Beautiful Bill Act** introduced a temporary above-the-line deduction under **IRC §163(h)(4)** for **qualified passenger vehicle loan interest** (QPVLI). The loan must be a new passenger vehicle (car, SUV, or similar) under 14,000 pounds, **final assembly in the U.S.**, and incurred after December 31, 2024.

([irs.gov](https://www.irs.gov/newsroom/treasury-irs-provide-transition-relief-for-2025-for-businesses-reporting-car-loan-interest-under-the-one-big-beautiful-bill?utm_source=openai)) Penalties under sections 6721-6722 won’t apply so long as this interim statement is provided. ([irs.gov](https://www.irs.gov/newsroom/treasury-irs-provide-transition-relief-for-2025-for-businesses-reporting-car-loan-interest-under-the-one-big-beautiful-bill?utm_source=openai)) ## Steps for borrowers & lenders - **Lenders**: Begin tracking qualifying passenger vehicle loans from individuals, compile interest data, ensure you can produce statements by Jan 31, 2026. Set up clearly marked borrower statements (online portal, monthly/annual or similar) as acceptable under the guidance. ([irs.gov](https://www.irs.gov/newsroom/treasury-irs-provide-transition-relief-for-2025-for-businesses-reporting-car-loan-interest-under-the-one-big-beautiful-bill?utm_source=openai)) - **Borrowers**: Keep all statements received and monitor interest paid—these will impact whether your QPVLI deduction applies. Keep in mind this deduction only for interest under personal use, and vehicles assembled in the U.S., as defined by law. ## Example comparison - If you finance a new SUV assembled in Michigan on May 1, 2025, for personal use, that interest qualifies. If the 2025 statement from your lender shows $1,200 interest, that can go toward your QPVLI deduction. - If the lender instead fails to issue misformed statements or misses the deadline, because penalties are waived under the transitional rule, you may avoid sanctions—but better to comply. ## Takeaway This OBBB provision gives borrowers a tax break and adds reporting obligations for lenders. Transitional relief in 2025 softens the burden, but full requirements will apply after this first year. Lenders should prepare systems now, while borrowers should track interest and confirm statements. The temporary benefit won’t last indefinitely, so thoughtful planning is essential.
