🔍 Strategy Summary:

  • A U.S.-assembled vehicle financed with a loan and used personally can qualify, whether electric or gasoline-powered.

  • The separate $7,500 EV credit applies through September 30, 2025, and may be combined with the interest deduction.

  • The vehicle registration and loan must be in the same name.

  • Reference: A $50,000 vehicle financed at 7.24% over 5 years has first-year interest of $3,620. A vehicle purchase price of approximately $138,000 would be needed for the maximum $10,000 interest deduction.

Item

Deduction method

Examples of eligible vehicles

GVWR over 6,000 lb: large SUVs and pickup trucks may qualify for a full deduction

GVWR of 6,000 lb or less: subject to IRS depreciation caps, approximately $20,000, plus or minus

📝 Example Tax-Saving Scenarios

[Personal Use]

  • Purchase a U.S.-made electric vehicle for $50,000 with financing before September 30, 2025


    → A $7,500 EV credit plus approximately $2,500–$4,000 in additional tax savings from the interest deduction

[Business Use]

  • Purchase a $90,000 SUV over 6,000 lb between January 20 and December 31, 2025, entirely for business use


    → 100% depreciation allows the entire $90,000 to be expensed


    → Approximately $18,900 in tax savings at a 21% corporate tax rate

  • Purchase a U.S.-made electric vehicle over 6,000 lb for $90,000 between January 20 and September 30, 2025

  • Bonus depreciation: immediately expense the full $82,500 ($90,000 minus $7,500), reducing corporate tax by approximately $17,325 at a 21% rate

  • EV tax credit: an additional direct $7,500 credit


    Total tax savings: $24,825
