How Does the Car Loan Interest Deduction Work?
The OBBBA created a new above-the-line deduction for interest paid on qualifying car loans. This means you can claim the deduction whether or not you itemize your taxes. The deduction applies to interest paid on loans secured by a new, US-assembled vehicle purchased for personal use.
Key Requirements
- Vehicle must be purchased after December 31, 2024 and before January 1, 2029
- Vehicle must be new (not used) and for personal use
- Vehicle must be finally assembled in the United States
- Loan must be secured by the vehicle (first lien)
- Annual deduction is capped at $10,000 of interest paid
Who Qualifies for the Car Loan Interest Deduction?
Most individual taxpayers who purchase a new, US-assembled vehicle with a loan qualify for this deduction, subject to income limits. The vehicle cannot be used primarily for business purposes (business use vehicles have separate deduction rules).
| Requirement | Details |
|---|---|
| Vehicle Type | New vehicle, US final assembly |
| Purchase Period | Jan 1, 2025 – Dec 31, 2028 |
| Loan Type | First lien, personal use |
| Annual Cap | $10,000 |
| Tax Form | Schedule 1-A (Form 1098-VLI from lender) |
Car Loan Interest Deduction Phase-Out
The deduction phases out for higher-income taxpayers based on Modified Adjusted Gross Income (MAGI). The phaseout reduces the deduction by $200 for every $1,000 of MAGI above the threshold.
