A car loan only produces the new interest deduction when the vehicle went through final assembly in the United States, the IRS says. The deduction is worth up to $10,000 a year, and it covers loans taken out after December 31, 2024. A loan on a car finished anywhere else earns nothing, however much interest gets paid.
Assembly is one of several tests, and all of them have to hold. The IRS says the loan must have been used to purchase a vehicle “originally used by the taxpayer,” must be secured by a lien on the vehicle and must be for a personal-use, nonbusiness vehicle. Lease payments do not qualify.
For anyone who has taken out a loan on a car, minivan, SUV or pickup since January 1, 2025, the question is where that particular vehicle was finished. The answer is on the vehicle itself, because the IRS points to the label at the dealership and the vehicle identification number, or VIN. Borrowers who bought a car built abroad can stop there, and borrowers who bought a U.S.-assembled car have more to check.

Final assembly is the test
The IRS Working Families Tax Cuts summary describes the rule under Section 70203. A qualified vehicle is a car, minivan, van, SUV, pickup truck or motorcycle that has a gross vehicle weight rating of less than 14,000 pounds and “underwent final assembly in the United States.”
The condition is narrower than the phrase made in America suggests. The IRS test is final assembly in the United States, and its summary says nothing about where parts came from or where an automaker is based. A vehicle rated at 14,000 pounds or more falls outside the definition by weight alone.
The test looks at one thing: where the vehicle was finished. The IRS names three ways to find out. They are the vehicle label at the dealership, the VIN, and the VIN decoder run by the National Highway Traffic Safety Administration.
The VIN does double duty. The IRS says the VIN must go on the return for any year the deduction is claimed. A borrower who skips it has no claim, and a borrower who looks it up before buying knows the answer before the first payment.
Lenders have a part, too. The IRS says lenders and other recipients of qualified interest must file information returns with the IRS and give borrowers a statement of the total interest received for the year.
The loan has its own tests
The loan must have been originated after December 31, 2024. A loan signed in December 2024 does not count, even if the car was bought and driven in 2025. The IRS also says a loan that is later refinanced is generally still eligible for interest on the refinanced amount, if the original loan was a qualifying one.
A borrower with a qualifying loan can claim for each year the deduction is in effect, subject to the income limits. Because the deduction runs 2025 through 2028, a five-year loan taken out in 2025 can produce a deduction in four of its years at most.
The loan must also be secured by a lien on the vehicle, which is how most auto loans work. The vehicle must be for personal use. A car bought for a business falls outside the rules, and so does a leased car, since the IRS says lease payments do not qualify.
The phrase “originally used by the taxpayer” is the only guidance the IRS summary gives on whether the car has to be new. It does not use the words new or used. Borrowers with a used-car loan can read that wording on the IRS page and press the question with a tax preparer.
The $10,000 ceiling and the $200,000 line
The maximum annual deduction is $10,000, according to the IRS. The deduction applies to the interest, not to the loan balance or the monthly payment, so a typical borrower’s deduction is a fraction of that ceiling. It runs for tax years 2025 through 2028.
Income sets a second limit. The IRS says the deduction phases out for taxpayers with modified adjusted gross income over $100,000, or $200,000 for joint filers. Phases out means the amount shrinks as income climbs past the line.
Both itemizers and people who take the standard deduction can claim it, the IRS says. Like any deduction, it lowers taxable income, and the tax saved depends on the bracket. A $2,000 deduction does not return $2,000.
Older drivers will find a second deduction in the same law. The IRS lists the enhanced deduction for seniors as a separate provision, with its own $6,000 per person amount. The open question for any borrower is whether the car passes all four tests together: U.S. final assembly, a loan dated after 2024, a personal-use vehicle, and an income under the line.
Was the car on the loan built in the United States?
The car-loan deduction fades out above $200,000 for couples, and one miss on the assembly or loan-date tests means it never applies. Retirees run into a different set of income lines on the same return, and those lines move real money.
Car-loan interest is one deduction. Cut Your Retirement Tax Bill: 12 Moves covers the lines around it for retirees, including the new $6,000 senior deduction ($12,000 for a couple) for 2025 through 2028 and how much of Social Security is taxed, worked out on one worksheet.
The 12 moves each name the form to use, such as Schedule 1-A, Form 5329 and Form W-4V, and the 2026 numbers are collected on one page.
