EV tax deductions for business owners

Two deductions, not one

Business owners can potentially claim both the §30D consumer EV credit (up to $7,500) and either Section 179 expensing or bonus depreciation on the same vehicle. These interact with each other and with your business structure — consult a CPA before filing. That said, the potential savings are enormous.

Section 179: immediate full expensing

Section 179 lets you deduct the full purchase price of qualifying business property in the year of purchase rather than depreciating it over 5 years. For vehicles over 6,000 lb GVWR used more than 50% for business, the full MSRP can be expensed. Many EVs qualify: Tesla Model X, Rivian R1T, Ford F-150 Lightning, Kia EV9.

Vehicles under 6,000 lb GVWR

For lighter EVs (Model 3, Ioniq 6, Bolt), Section 179 is capped at $12,200 in 2026 for passenger vehicles. However, bonus depreciation allows additional deductions. Combined with the consumer credit, lighter EVs still offer significant business tax benefits.

The §30D credit vs the §45W commercial credit

If your business buys an EV and it's titled to the business, you may qualify for the §45W Commercial Clean Vehicle Credit (up to $7,500 for under 14,000 GVWR) rather than the consumer §30D credit. These are separate credits — a business buying EVs should evaluate which applies.

Documentation to keep

IRS Form 4562 for Section 179, mileage log for every business trip (date, destination, business purpose, miles), receipt and invoice for the vehicle purchase, and documentation that business use exceeded 50%. Use an app like MileIQ or TripLog from day one.
