Car Loan Interest Deduction: Qualifying Loans and Vehicles
Most tax questions sound like arithmetic and turn out to be paperwork. This one is both.
The deduction for qualified passenger vehicle loan interest reduces the income you are taxed on. It is available to filers who itemize and to filers who take the standard deduction. The maximum is $10,000 for the year. It applies for tax years 2025 through 2028, and the return has to carry the vehicle identification number of the purchased vehicle.
The Kind of Tax Break This Is
It lowers taxable income, and the maximum annual amount is $10,000. It was enacted as Public Law 119-21, signed into law on July 4, 2025, and it is effective for 2025 through 2028.
Itemizing is not part of the test. The IRS states the deduction is available for both itemizing and non-itemizing taxpayers, so a filer who claims the standard deduction can still claim this one.
The claim goes on Schedule 1-A, Additional Deductions, which taxpayers attach to their Form 1040, 1040-SR, or 1040-NR when filing a 2025 tax return. The schedule was created to calculate and claim four deductions and consolidates them in one place, and anyone who qualifies for one or more of them can use it. Car loan interest is Part IV.
What the Loan and the Vehicle Have to Meet
To be eligible, the loan and the vehicle must meet certain requirements. The Schedule 1-A page states that for interest to be qualified passenger vehicle loan interest, it must be paid or accrued on a loan that generally meets all of a short list of requirements. The conditions below come in two kinds: things the loan and the vehicle have to satisfy, and a limit that depends on what the filer earns.
Requirements for the deduction for qualified passenger vehicle loan interest for tax years 2025 through 2028, as stated on the IRS pages.
| Requirement | What the IRS pages state | Where the requirement is stated |
|---|---|---|
| Loan timing | The loan was originated by the taxpayer after December 31, 2024 | Schedule 1-A, Part IV |
| Loan purpose and security | The proceeds were used to purchase an applicable passenger vehicle for personal use, lease payments do not qualify, and the loan is secured by a first lien on the purchased vehicle | Schedule 1-A, Part IV |
| Who used the vehicle first | The original use of the vehicle starts with the taxpayer, and used vehicles do not qualify | The fact sheet’s qualified-interest conditions |
| The vehicle itself | A car, minivan, van, SUV, pickup truck or motorcycle, with a gross vehicle weight rating of less than 14,000 pounds, that has undergone final assembly in the United States | The fact sheet’s qualified-vehicle definition |
| The filer’s income | The deduction phases out for taxpayers with modified adjusted gross income over $100,000, $200,000 for joint filers | Part I of Schedule 1-A |
Lease payments do not qualify. The purchase has to be one made for personal use that meets other eligibility criteria. If a qualifying vehicle loan is later refinanced, interest paid on the refinanced amount is generally eligible for the deduction.
The Vehicle Side of the Rules
A qualified vehicle is a car, minivan, van, SUV, pickup truck or motorcycle, with a gross vehicle weight rating of less than 14,000 pounds, that has undergone final assembly in the United States.
To verify final assembly, the IRS names the vehicle label at the dealership, the vehicle identification number, and the NHTSA VIN Decoder. The location of final assembly is listed on the vehicle information label attached to each vehicle on a dealer’s premises. Alternatively, taxpayers may rely on the vehicle’s plant of manufacture as reported in the vehicle identification number to determine whether a vehicle has undergone final assembly in the United States.
That route runs through a public database. The VIN Decoder website for the National Highway Traffic Safety Administration provides plant of manufacture information, and taxpayers can follow the instructions on that website to determine if the vehicle’s plant of manufacture was located in the United States.
The interest must be paid on a loan used to purchase a vehicle the original use of which starts with the taxpayer, and used vehicles do not qualify. The same conditions call for a personal use vehicle, not one for business or commercial use.
The VIN also has to travel with the claim. The taxpayer must include the vehicle identification number of the qualified vehicle on the tax return for any year in which the deduction is claimed.
Income and the Phase-Out
The IRS states that the deduction phases out for taxpayers with modified adjusted gross income over $100,000, $200,000 for joint filers.
The figure that drives it is computed on the schedule itself. Total modified adjusted gross income is calculated in Part I of Schedule 1-A, and the IRS states that the deductions on the schedule depend on an individual’s income and phase out at higher income levels. All four of the deductions on that schedule are subject to income phaseouts.
The Paperwork on Both Sides
The reporting side starts with the lender. In general, a business that receives $600 or more of interest from any individual for any calendar year on a qualified passenger vehicle loan must comply with the new reporting requirements. It files an information return with the IRS, and it furnishes the borrower a statement showing the total amount of interest received during the taxable year.
The filer’s side runs through Part IV. Part IV should only be completed if the taxpayer or their spouse, if married filing jointly, paid or accrued qualified passenger vehicle loan interest, and it is also where the vehicle identification number of the purchased vehicle is reported.
On the schedule, column (iii) is the total QPVLI paid in 2025 less the amounts reported in column (ii).
One more figure leaves the schedule for the main form. The total additional deductions are added and entered on Part VI of Schedule 1-A and on Form 1040, line 13b.
For 2025, Notice 2025-57 provides transitional relief for lenders and other interest recipients who are required to file information returns with the IRS and provide statements to borrowers. Under that guidance, the IRS will consider that lenders have met their reporting obligations for interest received on a qualified passenger car loan in 2025 if they make a statement available to the buyer indicating the total amount of interest received.
The notice names the acceptable channels. Lenders can meet the requirement by making that total available on an online portal that the buyer can easily access, in a regular monthly statement, on an annual statement that is provided to the buyer, or by other similar means designed to provide accurate information to the buyer regarding interest received.
A penalty piece rides along with the same relief. The IRS will not impose penalties on lenders for a failure to file information returns and provide payee statements if they satisfy their reporting obligations as described in the notice.
The 2025 Through 2028 Window
The clock is the plainest part of it. The deduction reaches interest paid on a qualified passenger vehicle loan during a taxable year beginning after Dec. 31, 2024, and before Jan. 1, 2029, provided the loan is incurred after Dec. 31, 2024, and the vehicle is purchased for personal use.
