Tax Alert: Introduction of Auto Loan Interest Deduction
The recently enacted One Big Beautiful Bill (OBBB) introduced a host of new and extended tax provisions. One provision of interest to many taxpayers is the introduction of a new deduction for interest paid on a loan secured by a qualifying personal passenger vehicle. Historically, interest paid on personal passenger vehicles was not deductible on an individual’s tax filing. The OBBB has introduced a new auto loan interest deduction provision enacting a change to this rule. For tax years 2025 through 2028, up to $10,000 of interest paid on qualifying loans, secured by qualified vehicles, is now deductible when computing an individual’s taxable income. This new deduction is available to individuals regardless of whether they itemize deductions or take the standard deduction.
Qualifying Vehicle
To qualify, the vehicle securing the loan must meet certain specifications. The new code outlines an applicable passenger vehicle as follows:
“(i) the original use of which commences with the taxpayer,
(ii) which is manufactured primarily for use on public streets, roads, and highways (not including a vehicle operated exclusively on a rail or rails),
(iii) which has at least 2 wheels,
(iv) which is a car, minivan, van, sport utility vehicle, pickup truck, or motorcycle,
(v) which is treated as a motor vehicle for purposes of title II of the Clean Air Act, and
(vi) which has a gross vehicle weight rating of less than 14,000 pounds.
Such term shall not include any vehicle the final assembly of which did not occur within the United States.”
Notably, to qualify for the new auto loan interest deduction, the vehicle purchased must be new and original to the taxpayer. Additionally, the gross vehicle weight rating cannot exceed 14,000 pounds. Finally, and perhaps most importantly, the vehicle must have “final assembly” in the United States to qualify for the deduction. This provision is anticipated to expand the vehicles available for the new deduction to include certain imported vehicles. Taxpayers and tax professionals should be diligent when verifying the qualifications of the vehicle for this deduction.
Qualifying Loan
In addition to criteria for the vehicle securing the indebtedness, the loan itself must also meet defined criteria to qualify for the additional interest deduction. First, the loan must be secured after December 31, 2024. Refinanced loans will also qualify for the deduction. However, the qualifying refinanced loan is only eligible up to the amount of such refinanced indebtedness. The loan must be used for the purchase of an “applicable vehicle,” as defined above. The vehicle must be for personal use, and the allowable interest deduction includes only amounts paid from tax years 2025 through 2028. Exceptions to a qualifying loan are also outlined in the legislation. The interest paid on the loan exceptions do not qualify for the additional deduction. The definition of disallowed loans for purposes of the new interest deduction includes the following:
“(i) A loan to finance fleet sales.
(ii) A loan incurred for the purchase of a commercial vehicle that is not used for personal purposes.
(iii) Any lease financing.
(iv) A loan to finance the purchase of a vehicle with a salvage title.
(v) A loan to finance the purchase of a vehicle intended to be used for scrap or parts.”
Income Limitation
Finally, the interest deduction is subject to a limitation based on the taxpayer’s Modified Adjusted Gross Income (MAGI). Up to $10,000 of interest paid on a qualifying loan secured by a qualifying vehicle is fully deductible if the taxpayer’s MAGI is below $100,000 for single filers ($200,000 for Married Filing Joint). The deduction is reduced by $200 for each $1,000 the taxpayer’s MAGI exceeds the income threshold.
This legislation also mandates additional reporting requirements. Institutions must provide information in a timely manner to taxpayers regarding interest paid on loans secured by specified passenger vehicles. We anticipate further guidance regarding identification of vehicles that meet the “final assembly in the United States” criteria.
Conclusion
Taxpayers and tax professionals are encouraged to engage in discussions early to identify opportunities for potential benefits related to the new auto loan interest deduction. With many criteria and limitations to be met to qualify, a comprehensive review of a taxpayer’s overall tax situation is warranted. Diligence and verification are needed when reviewing the applicability of this new deduction.
