A new federal tax break lets many households write off the interest they pay on a car loan — up to $10,000 a year — as long as the vehicle was assembled in the United States and bought new for personal use. The deduction comes out of the tax law signed in July 2025, and it runs for four tax years, covering 2025 through 2028. Because it is written to work whether you itemize or take the standard deduction, it reaches far more ordinary buyers than most tax breaks do.
What the $10,000 car-loan interest deduction actually covers
The Treasury Department and the IRS spelled out the rules in guidance issued at the end of 2025, describing it as the “No Tax on Car Loan Interest” provision. The deduction applies to interest paid on a loan taken out after December 31, 2024, to buy a new made-in-America vehicle for personal use. The annual cap is $10,000 of interest — not $10,000 off your tax bill, but up to that much interest subtracted from the income the government taxes.
Crucially, the write-off is available to taxpayers who claim the standard deduction as well as those who itemize. That is unusual. Most deductions tied to borrowing, like the mortgage-interest deduction, only help people who itemize, which today is a minority of filers. Here, a family that takes the standard deduction can still knock qualifying car-loan interest off their taxable income.

Which vehicles and loans qualify
Not every car purchase counts. A qualifying vehicle is a car, minivan, van, SUV, pickup truck, or motorcycle with a gross vehicle weight rating under 14,000 pounds — and, critically, one that underwent final assembly in the United States. The IRS says you can confirm the assembly location on the vehicle information label attached to the car on the dealer’s lot, or by checking the plant of manufacture encoded in the vehicle identification number (VIN). Buyers who want certainty can ask the dealer to point to that label before signing.
The loan itself has to meet a few tests too. Per the IRS’s form guidance, the loan must have been originated after December 31, 2024, the money must have gone toward buying an applicable passenger vehicle for personal use, and the loan must be secured by a first lien on that vehicle. Several common situations are shut out. Used vehicles do not qualify, because the car must be new and originally used by the taxpayer. Lease payments do not count. And business or commercial use falls outside the personal-use requirement.
The income phase-out that shrinks the break for higher earners
The deduction is aimed at middle-income households, and the law backs that up with an income limit. It begins to phase out once modified adjusted gross income tops $100,000 for a single filer, or $200,000 for a married couple filing jointly. Above those thresholds, the amount you can deduct falls as income rises, so higher earners see a reduced break or none at all. For a typical working family financing a new truck or SUV, though, the full deduction is generally in reach.
It is worth being realistic about the size of the benefit. The deduction lowers taxable income rather than handing back a flat dollar amount, so the actual savings depend on your tax bracket and on how much interest you pay. Interest is usually heaviest in a loan’s early years, which is when the write-off tends to be most valuable. A borrower paying, say, several thousand dollars of interest in the first year of a new-car loan could shelter that interest from tax, with the exact dollar savings scaling to their bracket.
How you claim it — the new Schedule 1-A
The deduction is not automatic. You claim it on a new IRS form, Schedule 1-A, Additional Deductions, which you attach to your Form 1040, 1040-SR, or 1040-NR. Car-loan interest is handled in Part IV, “No Tax on Car Loan Interest,” and the schedule requires you to enter the VIN of the vehicle you bought. That reporting requirement is one more reason to hold onto your loan paperwork and the vehicle’s documentation.
Lenders play a role as well. The IRS has directed banks and other loan servicers to file information returns reporting the interest they received on qualifying vehicle loans, and to send that information to borrowers — much like the year-end interest statements homeowners already receive. Those statements are what let you substantiate the interest you are deducting. Because the provision covers tax years 2025 through 2028, it is scheduled to sunset after 2028 unless Congress extends it, so buyers weighing a new, U.S.-assembled vehicle in the next few years are the ones positioned to use it. As always, the safest move is to confirm your own eligibility against the IRS guidance or with a tax professional before counting on the deduction.
