Auto Loan Interest Deduction

July 2025

Auto Loan Interest Deduction

Effective July 4, 2025, the One Big Beautiful Bill Act (OBBBA) introduces significant amendments to federal vehicle incentives, which warrant immediate attention for their potential impact on dealership operations and customer communications.

A new federal auto loan interest deduction allows qualifying customers to save up to $10,000 annually on new vehicle loan interest across all vehicle lines that have undergone final assembly in the United States and have a gross vehicle weight rating (GVWR) of less than 14,000 pounds.

This new federal deduction presents a significant advantage for customers considering a new Ford or Lincoln vehicle. Ford's longstanding commitment, exemplified by its "Ford For America" campaign, ensures that a substantial portion of its vehicle lineup undergoes final assembly in the U.S. Consequently, many Ford and Lincoln models will qualify for this valuable federal tax deduction, offering a direct financial incentive for choosing domestically produced vehicles.

Eligibility 


A new federal auto loan interest deduction has been established, offering financial benefits to qualifying customers.

Due to uncertainties surrounding how FCTP vehicles will be treated for purposes of the auto interest deduction, when purchasing a FCTP vehicle a customer should be advised to consult with their tax advisor.

Key provisions of this deduction are as follows:

Deductible Amount

Eligible taxpayers may deduct up to $10,000 in annual interest paid or accrued on loans for qualifying new personal use vehicles effective for 2025 through 2028.

Applicability Period

This deduction applies to new Electric Vehicles (EVs), Hybrid vehicles,and Internal Combustion Engine (ICE) vehicles with loans originating between January 1, 2025, and December 31, 2028.

Qualifiers

To qualify for the deduction, the interest must be paid or accrued on a loan that is:

  1. originated after December 31, 2024
  2. used to purchase a vehicle, the original use of which starts with the taxpayer (used vehicles do not qualify)
  3. for a personal use vehicle (not for business or commercial use) and
  4. secured by the first lien on the vehicle

Vehicle Eligibility - U.S. Final Assembly

To qualify, vehicles must have undergone final assembly in the United States and have a gross vehicle weight rating (GVWR) of less than 14,000 pounds. See the following page for a list of qualifying vehicles

Customer Eligibility

Staff should be prepared to bring awareness to customers regarding potential income eligibility thresholds associated with this deduction. Deduction begins to phase out for taxpayers with modified adjusted gross income over $100,000 ($200,000 for joint filers). Eligible customers can include the deduction on their Tax Return.
