There is a new line in the car budget, but it comes with more fine print than a windshield sticker. The federal deduction for qualifying car-loan interest can be worth up to $10,000 a year through 2028. It does not make every payment deductible.
The vehicle has to qualify
The car, minivan, van, SUV, pickup or motorcycle must be new to the taxpayer, weigh under 14,000 pounds and have final assembly in the United States. The IRS points buyers to the vehicle label and NHTSA VIN decoder for the assembly location. A familiar American brand name alone is not enough.
The loan has rules too
The loan generally must have originated after December 31, 2024, be secured by the vehicle and finance a personal-use purchase. Lease payments do not qualify. Interest on a later refinance may remain eligible to the extent it relates to the qualifying balance.
Income can reduce the deduction
The maximum annual deduction is $10,000. It begins phasing out when modified adjusted gross income exceeds $100,000 for a single filer or $200,000 for a married couple filing jointly. Both itemizers and non-itemizers may qualify, and the VIN must be included on the return.
Do not finance extra interest for a tax break
A deduction reduces taxable income; it does not reimburse interest dollar for dollar. Compare the out-the-door price, APR, term and total of payments first. A shorter or cheaper loan can save more than the deduction on a longer, expensive one.
Before signing
Verify final assembly with the exact VIN, ask the lender how interest will be reported and keep the purchase and loan documents. Then have a qualified tax professional confirm how the deduction fits your return. The tax line should improve a good deal, not rescue a bad one.
