Section 179 Vehicle Deduction: Qualifying Cars & Trucks 2026
Section 179 lets businesses deduct the full purchase price of qualifying vehicles in 2026—up to $31,300 for heavy SUVs and trucks over 6,000 lbs GVWR, with a $22,000 bonus depreciation cap on top.
How Section 179 Works for Vehicles
Section 179 is an expensing election that lets a business write off the full purchase price of qualifying equipment in the year it is placed in service, rather than depreciating it over several years. For vehicles, the deduction hinges on weight and business use. Light vehicles (under 6,000 lbs GVWR) face strict annual depreciation caps. Heavy vehicles—trucks, vans, and SUVs rated over 6,000 lbs—qualify for much larger immediate deductions, which is why business owners often favor them.
2026 Deduction Limits by Vehicle Type
| Vehicle Type | GVWR | Section 179 Limit | Notes |
|---|---|---|---|
| Passenger car | < 6,000 lbs | $12,200 (yr 1 cap) | Strict annual depreciation limits |
| Light truck/SUV | < 6,000 lbs | $12,200 (yr 1 cap) | Same caps as passenger cars |
| Heavy SUV | 6,001-14,000 lbs | $31,300 | Full Section 179 expensing |
| Heavy pickup/van | > 6,000 lbs | $31,300 | Often qualifies for full deduction |
| Cargo van (over 6,000 lbs) | > 6,000 lbs | $31,300 | Built for cargo, no passenger limits |
The Business-Use Requirement
Section 179 requires more than 50% business use, and the deduction is prorated by the business-use percentage. A truck used 75% for business means you expense 75% of the cost. Personal use reduces the deduction dollar for dollar. Keep a mileage log—contemporaneous records are the only documentation the IRS accepts if audited. Mixing business and personal use is fine, but you need to be able to prove the split, and the vehicle must be placed in service during the tax year you claim the deduction.
Bonus Depreciation on Top of Section 179
Bonus depreciation is a separate provision that applies after Section 179. In 2026, bonus depreciation sits at 40% for qualifying property (it has been phasing down 20% per year from 100% in 2022). For a $60,000 heavy SUV used 100% for business, you could expense $31,300 under Section 179, then take 40% bonus depreciation on the remaining $28,700, plus regular depreciation.

Which Vehicles Qualify for the Heavy Deduction
To clear the 6,000-lb GVWR threshold, popular qualifying models include full-size pickups like the Ford F-150, Chevy Silverado 1500, and Ram 1500 (depending on configuration), plus large SUVs like the Chevy Suburban, Ford Expedition, and Toyota Sequoia. The GVWR is on the driver’s door jamb sticker—not the curb weight. Some midsize SUVs straddle the line depending on trim and options, so verify the specific vehicle’s GVWR before assuming it qualifies. Cargo vans like the Ford Transit and Ram ProMaster almost always qualify.
Common Mistakes to Avoid
- •Assuming a vehicle qualifies based on model name—always check the GVWR sticker for the specific configuration.
- •Claiming 100% business use without a mileage log—the IRS disallows inflated estimates routinely.
- •Forgetting that the deduction recaptures if business use drops below 50% in a later year.
- •Missing the placed-in-service deadline—the vehicle must be in use by December 31, not just ordered or paid for.
