New Tax Relief: Deducting Auto Loan Interest Under the One Big Beautiful Bill Act
High interest rates have made purchasing a vehicle a heavier financial lift for many families over the last few years. However, proposed regulations under the new legislative package—known as the One Big Beautiful Bill Act—offer a reprieve for borrowers looking to buy American.
Effective for loans originated after December 31, 2024, this provision introduces a temporary deduction for interest paid on qualified passenger vehicles. This tax break is slated to run through the 2028 tax year. At THE TAX CUTTERY®, we view this as a significant planning opportunity for clients anticipating a major vehicle purchase.
Who Qualifies for the Deduction?
This benefit is designed for individuals, certain trusts, estates, and disregarded entities. However, Congress has included specific income thresholds to target the relief. The ability to claim this deduction phases out if your modified Adjusted Gross Income (AGI) exceeds:
$150,000 for single filers and heads of household.
$250,000 for married couples filing jointly.
If your income falls within the eligible range, the financial impact can be substantial. There is an annual cap of $10,000 per tax return. Uniquely, married taxpayers filing separately can each claim up to $10,000, provided they meet individual eligibility requirements.
Vehicle Eligibility: It Must Be "Made in the USA"
Not every car on the lot will trigger this tax break. To align with domestic manufacturing goals, the deduction is strictly for new passenger vehicles assembled in the United States. This includes cars, SUVs, minivans, pickup trucks, and motorcycles with a gross vehicle weight rating under 14,000 pounds.
Before signing paperwork, verify the vehicle's final assembly point using its VIN. You can check the status officially here: Welcome to VIN Decoding : provided by vPIC
Standard Deduction vs. Itemizing
One of the most distinct features of this new rule is how it is claimed. Typically, interest deductions are itemized. However, this vehicle interest deduction is treated as a reduction to taxable income available even to those who take the standard deduction. Whether you itemize or not, you can benefit.
You will claim this on a new schedule attached to your Form 1040, which requires listing the vehicle's VIN.
The "Personal Use" Requirement
This deduction targets personal vehicles. To qualify, you must anticipate using the vehicle for personal purposes more than 50% of the time when you buy it. The regulations offer some flexibility here: you do not need to adjust this estimate in future years, even if your actual personal use percentage drops later.
For business owners and freelancers who drive mixed-use vehicles, strategic planning is required. You can still claim a business expense deduction for the business-use portion of the interest, while the remainder may be claimed under this new schedule—reduced proportionally. Double-dipping is not allowed.
What Expenses Qualify?
The deduction covers interest on the financed purchase price. It also extends to interest on financed amounts directly linked to:
Sales taxes
Vehicle fees
Service plans
Crucially, the loan must be secured by the vehicle and originate from an independent lender, such as a bank or credit union. Interest on loans from family members does not qualify, nor does interest paid on leased vehicles.
Documentation and Reporting
For the 2025 tax year, lenders may provide a simple statement showing the interest paid. In subsequent years, expect to receive the new Form 1098-VLI if you paid at least $600 in interest. This form will provide the comprehensive data needed for your return.
Plan Ahead with THE TAX CUTTERY®
While this deduction offers welcome relief, the intersection of income phaseouts, business-use calculations, and specific vehicle requirements can get complicated. As we approach the filing season, ensuring you have the right documentation—and that your income falls within the phaseout limits—is vital.
