This legislation introduces a new federal income tax deduction for individuals who pay interest on loans used to acquire specific motor vehicles. The bill amends the Internal Revenue Code of 1986 to allow an above-the-line deduction , meaning taxpayers can claim it regardless of whether they itemize other deductions. The deduction is capped at $2,500 annually and applies to "qualified motor vehicle interest." To qualify, the interest must be incurred on or after January 1, 2025, for a loan used to purchase a "qualified motor vehicle," and the loan must be secured by that vehicle. A key requirement for a vehicle to be considered "qualified" is that its final assembly must occur within the United States . Additionally, the vehicle must be primarily for public road use, have at least four wheels, and a gross vehicle weight rating under 14,000 pounds. This provision aims to incentivize the purchase of domestically assembled vehicles. The amendments made by this bill will apply to taxable years beginning after December 31, 2025.
