The qualified passenger vehicle loan interest deduction is a temporary federal deduction for eligible interest paid on a loan used to buy a qualifying new vehicle for personal use. It is available for tax years 2025 through 2028, is limited to $10,000 per year, and is calculated on Schedule 1-A.
The indebtedness must generally:
A lease does not qualify because the taxpayer did not use a qualifying purchase loan. Interest on a qualifying loan that is later refinanced may remain eligible if the refinanced debt is secured by a first lien on the same vehicle, but only to the extent of the eligible outstanding balance at refinancing.
An applicable passenger vehicle generally must:
Final assembly can be checked on the dealer's vehicle-information label or through plant information associated with the VIN. The taxpayer must include the VIN on the return for a year in which the deduction is claimed.
At the time the loan is incurred, the taxpayer generally must expect the vehicle to be used more than 50% for personal use by the taxpayer or certain related or household individuals. Employee use is treated differently from use in another trade or business, and income-producing use must be considered.
Suppose a taxpayer buys a qualifying vehicle and expects 85% family use and 15% rideshare use. The IRS instructions indicate that the vehicle can be considered purchased for personal use. However, interest potentially deductible elsewhere on the return — such as through the actual vehicle expense method — cannot be deducted twice. Mixed-use facts should be documented.
Start with qualified interest paid or accrued during the year and cap it at $10,000. Do not use the total loan payment; only the interest component is relevant.
The deduction phases out when Schedule 1-A MAGI exceeds $100,000, or $200,000 on a joint return. It is reduced by $200 for each $1,000, or fraction of $1,000, above the threshold.
Alex and Jordan file jointly, pay $3,400 of qualified interest, and have MAGI of $207,200. The excess is treated as eight $1,000 increments, causing a $1,600 reduction. Their deduction is $1,800.
Because the maximum reduction reaches $10,000 after 50 increments, no deduction generally remains once MAGI reaches $150,000 for a nonjoint filer or $250,000 for a joint filer.
Keep the purchase agreement, retail installment contract or promissory note, lien documentation, annual lender interest statement, payment history, refinancing records, dealer label, VIN, vehicle weight information, and proof of U.S. final assembly. For mixed use, keep mileage and use records.
Lenders and other interest recipients may have information-reporting obligations when they receive at least the statutory amount of interest. A statement from the lender helps, but the taxpayer remains responsible for eligibility and for reporting the VIN.
The deduction is calculated in Part IV of Schedule 1-A. Eligible taxpayers may claim it whether they itemize or take the standard deduction. Interest also deductible as a business or income-production expense cannot be deducted again on Schedule 1-A.
The deduction lowers taxable income; it does not directly reduce tax dollar-for-dollar. A $3,000 deduction does not create a $3,000 refund.
The federal deduction applies for 2025 through 2028 unless the law changes. California does not conform to the qualified passenger vehicle loan interest deduction. A federal Schedule 1-A amount therefore should not automatically reduce California taxable income.
California taxpayers may need separate treatment for legitimate business-use vehicle interest under otherwise applicable state rules, such as through the actual vehicle expense method. That is distinct from this temporary federal personal-use deduction.
Heath Income Tax can review the loan and vehicle documents, calculate the MAGI limitation, separate any business-use treatment, and handle California nonconformity.
Does every new car qualify?
No. The vehicle, final-assembly location, weight, original-use, loan, lien, and use rules must all be reviewed.
Can lease interest or finance charges qualify?
Lease payments do not qualify under this purchase-loan deduction.
Can a refinanced loan qualify?
Potentially, if the original debt qualified and the refinancing meets the lien and balance limitations.
Is the deduction available with the standard deduction?
Yes, when all eligibility requirements are met.
