Car Loan Interest Is Tax-Deductible Again: How the OBBBA $10,000 Above-the-Line Deduction Works for U.S.-Assembled Vehicles From 2025 Through 2028

The OBBBA restores a personal car-loan interest deduction—up to $10,000 per year, above-the-line, for tax years 2025 through 2028—on new U.S.-assembled vehicles financed after December 31, 2024. Mechanics covered include the MAGI phase-out starting at $100K single / $200K joint, Form 1098-VLI reporting beginning in 2026, mandatory VIN entry on Form 1040, and edge cases for refinances, trade-ins, leases, and co-signers.
