Americans financing certain new vehicles can deduct up to $10,000 a year in car loan interest under a temporary federal tax break, and the IRS has now finalized regulations explaining who qualifies. The deduction was created by the One Big Beautiful Bill Act signed into law July 4, 2025, and applies to qualifying vehicle loans incurred after December 31, 2024. It is available for tax years 2025 through 2028 under current law.
One particularly important feature is that taxpayers don’t have to itemize deductions to claim it. Someone who takes the standard deduction may still qualify for the car loan interest deduction. But the $10,000 headline comes with several significant restrictions.
The Vehicle Generally Must Be New and Assembled in the United States
The deduction doesn’t apply to every car loan. To qualify, the loan must be used to purchase an eligible passenger vehicle for personal use, and the debt must be secured by a first lien on the vehicle. The original use of the vehicle must also begin with the taxpayer, which generally means the vehicle must be treated as new when purchased.
Another major requirement is final assembly in the United States. The IRS rules allow taxpayers to determine the final assembly location using information encoded in the vehicle identification number or the final assembly point shown on the vehicle’s required label.
Eligible vehicle classifications can include cars, minivans, vans, SUVs, pickup trucks and motorcycles that satisfy the applicable requirements. Vehicles must also have a gross vehicle weight rating below 14,000 pounds. Leases don’t qualify, nor do loans financing certain fleet sales, non-personal commercial vehicles, salvage-title vehicles, or vehicles intended for scrap or parts.
The Deduction Is Worth Up to $10,000 a Year
Eligible taxpayers can deduct qualified interest paid or accrued during the year, subject to a maximum of $10,000 per tax return per year. That doesn’t mean buying a qualifying vehicle automatically produces a $10,000 deduction. A taxpayer who pays $2,800 of qualifying interest during the year, for example, generally has only $2,800 potentially available for the deduction before considering other limitations. The tax savings also aren’t the same as the deduction itself.
A $3,000 deduction doesn’t mean the IRS sends someone an extra $3,000. Instead, a deduction generally reduces the amount of income subject to federal income tax. The tax break is temporary under current law and applies to qualifying interest for tax years 2025 through 2028.
Higher-Income Taxpayers May Get a Smaller Deduction
Income can reduce or completely eliminate the tax break. The deduction begins phasing out when modified adjusted gross income exceeds $100,000 for most filers or $200,000 for married couples filing jointly.
For each $1,000—or portion of $1,000—above the applicable threshold, the otherwise allowable deduction is reduced by $200. That means shoppers shouldn’t assume they’ll receive the full tax benefit simply because the vehicle and loan meet the other requirements.
Taxpayers should also remember that eligibility for a deduction is only one factor to consider when financing a vehicle. Paying thousands of dollars of additional interest solely to receive a tax deduction generally doesn’t make that interest free.
Your VIN Will Matter at Tax Time
Taxpayers claiming qualified passenger vehicle loan interest must include the vehicle’s VIN on their federal income tax return. The VIN is important both for identifying the vehicle and for helping establish whether its final assembly occurred in the United States. The IRS regulations point taxpayers toward vehicle-manufacturing information that can be used to determine final assembly location.
Consumers shopping for a new vehicle who expect to use the deduction may therefore want to verify final assembly before completing the purchase rather than assuming that an American brand name automatically means the vehicle qualifies. Where a vehicle was assembled—not simply the automaker’s headquarters or brand identity—is what matters for this requirement.
Lenders Will Have New Reporting Requirements
The final regulations also establish reporting requirements intended to help taxpayers document the interest they paid. A lender or other qualifying business that receives $600 or more in interest during a calendar year from an individual on a specified passenger vehicle loan generally must file an information return with the IRS and furnish a statement to the borrower.
The reporting requirements are established under new Internal Revenue Code Section 6050AA. Businesses required to file at least 10 information returns of any type during a calendar year generally must file electronically under the applicable IRS rules.
These reporting requirements should eventually give qualifying borrowers documentation that can help them determine the interest associated with an eligible vehicle loan.
Don’t Buy a More Expensive Car Just for the Tax Deduction
The new deduction can reduce the after-tax cost of borrowing for someone who already needs a qualifying vehicle, but it shouldn’t make an unaffordable car loan suddenly affordable. Consider someone who pays $4,000 in qualifying car loan interest and is able to deduct the entire amount. The financial benefit is the tax savings produced by that $4,000 deduction—not reimbursement of the $4,000 of interest.
Vehicle price, interest rate, loan term, insurance, maintenance, depreciation and the monthly payment can still matter far more to a household budget than the deduction. The tax break is also scheduled to disappear after 2028 unless Congress extends it, while a five-, six- or seven-year auto loan could continue long after the deduction expires.
For shoppers comparing vehicles, the better question isn’t simply, “Does this car qualify for the deduction?” It’s whether the total cost of the vehicle and financing still makes sense without counting on a temporary tax break.
