Section 179 Vehicle Deduction 2026: Which Work Trucks Actually Qualify
Section 179 lets businesses deduct up to $31,300 for heavy SUVs/trucks over 6,000 lbs GVWR in 2026, with bonus depreciation stacked on top — but you need a mileage log.
How Section 179 works for vehicles
Section 179 lets a business write off the full purchase price of qualifying equipment in the year it is placed in service. For vehicles the deduction hinges on weight and business use. Light vehicles under 6,000 lbs GVWR face strict annual depreciation caps, while heavy vehicles over 6,000 lbs get much larger immediate deductions — which is why business buyers favor them.
2026 deduction limits
| Vehicle | GVWR | Section 179 limit |
|---|---|---|
| Passenger car | < 6,000 lbs | $12,200 (yr-1 cap) |
| Light truck/SUV | < 6,000 lbs | $12,200 (yr-1 cap) |
| Heavy SUV | 6,001–14,000 lbs | $31,300 |
| Heavy pickup/van | > 6,000 lbs | $31,300 |
The 50% business-use rule
Section 179 needs more than 50% business use, and the deduction is prorated by that percentage. A truck 75% for business deducts 75% of cost. Keep a contemporaneous mileage log — it is the only documentation the IRS accepts. The vehicle must be placed in service during the tax year you claim it.
Bonus depreciation on top
Bonus depreciation is separate and applies after Section 179. In 2026 it sits at 40% (phasing down 20%/year from 100% in 2022). A $60k heavy SUV used 100% for business could take $31,300 under 179, then 40% bonus on the remainder.

Which vehicles clear 6,000 lbs
Full-size pickups (F-150, Silverado 1500, Ram 1500 depending on config), large SUVs (Suburban, Expedition, Sequoia), and cargo vans (Transit, ProMaster) usually qualify. The GVWR is on the driver’s door-jamb sticker — not curb weight. Some midsize SUVs straddle the line by trim, so verify the specific vehicle.
Mistakes that get denied
- Assuming the model name qualifies — check the GVWR sticker for the exact config.
- Claiming 100% business use with no log — the IRS disallows estimates.
- Forgetting recapture if business use drops below 50% later.
- Missing the Dec 31 placed-in-service deadline (ordered/paid is not enough).
