Millions of car buyers who finance a new vehicle assembled in the United States can now subtract up to $10,000 in annual loan interest from their taxable income, regardless of whether they itemize deductions. The IRS confirmed the new break applies to 2025 tax returns through a dedicated form called Schedule 1-A, created under the One, Big, Beautiful Bill Act. For households already stretched by elevated car prices and interest rates, the deduction could cut their federal tax bill by hundreds or even thousands of dollars each year.
How the $10,000 car loan interest deduction works
The deduction covers what the tax code now calls “qualified passenger vehicle loan interest” under IRC Section 163. Eligible taxpayers can claim it whether they itemize or take the standard deduction, a distinction that opens the benefit to the large majority of filers who do not itemize. The IRS directs filers to report the amount on Schedule 1-A, titled Additional Deductions, which also handles related breaks for tips, overtime, and seniors enacted under the same law.
To qualify, the vehicle must have final assembly in the United States, and the taxpayer must include the vehicle identification number on the return. Buyers can verify assembly location through NHTSA’s VIN decoder before purchasing. The deduction phases out for higher earners: it is reduced by $200 for every $1,000 of modified adjusted gross income above $100,000 for single filers and $200,000 for joint filers. That means a single taxpayer earning $150,000 would lose the entire benefit, while a married couple filing jointly would see it fully phase out at $250,000.
The law caps the deduction at $10,000 in interest per return, not per vehicle. Households with multiple qualifying car loans must total their interest and then apply the cap. Interest on leases, business vehicles, or vehicles used primarily for rideshare or delivery work generally falls under separate rules and does not count toward this consumer-focused deduction. Taxpayers who refinance a qualifying loan can keep claiming the break, as long as the same vehicle remains the collateral and all other requirements continue to be met.
Lender reporting rules are still catching up
One practical wrinkle: lenders do not yet have a standardized form to report car loan interest the way mortgage servicers issue a 1098 for home loan interest. Treasury and the IRS acknowledged this gap by issuing Notice 2025-57, granting transition relief for 2025 so that lenders can use substitute statements while the agencies finalize reporting requirements. Proposed regulations published in the Federal Register spell out what information those statements must contain, and the public comment period is open on Regulations.gov.
For buyers filing 2025 returns in early 2026, this means the interest figure may arrive in an unfamiliar format rather than a familiar tax form. Borrowers should confirm the total with their lender, review their year-end loan statements, and keep copies with their tax records. If a substitute statement appears incomplete or confusing, taxpayers can request a corrected version or a detailed payment history to verify the interest amount before filing.
The IRS announcement labeled IR-2026-28 outlines the schedule taxpayers will use to claim the deduction and confirms the form is available now for software developers and tax professionals. According to that guidance, the agency expects most major tax preparation platforms to integrate the new lines automatically, prompting eligible filers to enter their car loan interest and vehicle information during the interview process.
Part of a broader package for workers and retirees
The car loan interest break is one of several new deductions created by the One, Big, Beautiful Bill Act, which Congress framed as targeted relief for working Americans and older adults. In an overview of the law’s provisions, the IRS highlights new rules for tips, overtime, and seniors alongside the vehicle interest deduction, emphasizing that all of them are claimed on Schedule 1-A. Together, these changes move more relief “above the line,” meaning taxpayers can benefit even if they do not itemize.
For policymakers, the car loan provision responds to a spike in average monthly payments and interest costs on new vehicles, particularly for middle-income buyers who rely on financing. For taxpayers, the practical effect is a larger deduction base that can reduce taxable income directly, rather than a nonrefundable credit that might be limited by tax liability. However, because the benefit phases out at higher incomes and is limited to U.S.-assembled vehicles, it is not universal and may influence some buyers’ choices at the margin.
Tax professionals recommend that consumers planning a new car purchase in 2025 factor the deduction into their overall budget but avoid letting it drive the decision to take on more debt. A federal tax break can soften the cost of borrowing, but it does not change the underlying obligation to repay principal and interest. As lenders, software providers, and the IRS refine their systems ahead of the 2026 filing season, taxpayers who keep accurate records and understand the new rules will be best positioned to capture the full value of the deduction.
