Taxpayers who bought a car with a loan can deduct up to $10,000 of the interest, but the IRS will not allow the deduction unless three things are true: the vehicle identification number is reported on Schedule 1-A, the loan was originated after Dec. 31, 2024, and the loan is secured by a first lien on the vehicle. A missing VIN or a loan that fails either of the other tests means no deduction.
The conditions come from the IRS fact sheet on Schedule 1-A, the new form for additional deductions. The car-loan interest deduction sits in Part IV of that schedule and applies to a 2025 tax return.
The three conditions in the IRS’s own words
On origination, the IRS says the loan must have been “originated by the taxpayer after December 31, 2024.” A loan taken out on Dec. 31, 2024 or earlier does not count, however new the car. On the lien, the IRS says the loan must be “secured by a first lien on the purchased vehicle.”
On the VIN, the agency says the number “of the purchased vehicle must be reported on Schedule 1-A.” The IRS also says the loan proceeds must have been used to buy an applicable passenger vehicle for personal use, and that lease payments do not qualify.
Does a particular loan clear the tests?
Anyone who financed a car in the past two years has the same three things to check: the date on the loan paperwork, whether the lender holds the first lien, and the VIN on the title or registration. A loan that is not secured by a first lien on the car does not meet the test as the IRS states it.

The deduction is claimed by the taxpayer, or by the spouse on a joint return, who paid or accrued the interest. For 2025 the IRS says the amount is the qualified vehicle loan interest paid in that year, less any amounts reported in the form’s earlier column. Interest paid on a refinanced amount is generally eligible if the original loan qualified.
What the deduction is worth and who loses it
The cap is $10,000 for the year, and it is a ceiling rather than a flat amount: the deduction equals the interest actually paid, up to that limit. The IRS has said the deduction applies for 2025 through 2028 and that it phases out for taxpayers with modified adjusted gross income over $100,000, or $200,000 for joint filers.
The deduction lowers taxable income. It is not a refund of the interest, so the saving depends on the filer’s tax bracket. A taxpayer in the 12 percent bracket who paid $2,000 of qualifying interest would cut the tax bill by roughly $240, before any phase-out.
The IRS says the deduction is available whether a taxpayer itemizes or takes the standard deduction, so a retiree who takes the standard deduction can still use it. All four deductions on Schedule 1-A, which also cover tips, overtime and the senior deduction, are subject to income phase-outs.
Which vehicles count
A qualified vehicle, according to the IRS, is a car, minivan, van, SUV, pickup truck or motorcycle with a gross vehicle weight rating under 14,000 pounds. Final assembly must have taken place in the United States, and the vehicle’s original use must begin with the taxpayer, so used cars do not qualify.
The IRS says the assembly location appears on the vehicle information label. Taxpayers can also check the plant of manufacture in the VIN with the federal NHTSA VIN decoder. That is why the VIN matters twice: it goes on the form, and it also helps show the car was assembled in the United States.
Lenders and the paperwork
Lenders and other recipients of qualifying interest must file information returns with the IRS and give borrowers a statement of the total interest received. The IRS says it will provide transition relief for 2025 for interest recipients subject to the new reporting rules, so a borrower may not receive a tidy statement for that year and may have to total the interest from loan records.
Schedule 1-A and its instructions are available on the IRS forms and publications page, where the form can be downloaded free.
Is the car loan one that clears all three tests?
A deduction with three conditions is easy to lose by skipping one. A missing VIN, a loan dated on the wrong side of Dec. 31, 2024 or a lien in the wrong position can turn a deduction of up to $10,000 into nothing, and the car-loan line is only one of several places a retiree’s tax bill gets set.
