What is the Section 179 Deduction?
Section 179 of the IRS tax code allows businesses to deduct the full purchase price of qualifying vehicles and equipment in the year they are placed into service, rather than depreciating the cost over several years. For fleet managers and business owners, this means a significant reduction in taxable income in the same fiscal year your vehicles hit the road. To qualify, the vehicle must be used more than 50% for business purposes and must be placed into service by December 31, 2026.
2026 Section 179 Deduction Limits by Vehicle Class
The IRS draws a critical line at 6,000 lbs Gross Vehicle Weight Rating (GVWR), which is the manufacturer’s maximum loaded weight rating, not the curb weight. Always verify GVWR on the door jamb sticker of the specific trim and configuration you are considering, as optional packages can push a vehicle over the threshold.
Light Vehicles (Under 6,000 lbs GVWR): Most passenger sedans and smaller crossovers fall into this category. For 2026, these vehicles are subject to luxury auto limits, capping the combined first-year Section 179 and bonus depreciation deduction at approximately $20,200.
Heavy Vehicles (6,000 to 14,000 lbs GVWR): This is where most full-size trucks and SUVs land, including the Chevrolet Silverado 1500, Silverado HD, GMC Sierra 1500, Sierra HD, Chevrolet Tahoe, Suburban, and GMC Yukon. For 2026, heavy SUVs carry a $32,000 Section 179 cap, but when combined with the reinstated 100% bonus depreciation, businesses can deduct significantly more in year one. Pickup trucks with a cargo bed of six feet or longer are exempt from the SUV cap and may qualify for full Section 179 expensing up to the overall limit.
True Commercial Vehicles (Over 14,000 lbs GVWR or Modified for Non-Personal Use): For 2026, the Section 179 maximum deduction is $2,560,000, with the deduction beginning to phase out dollar-for-dollar when total qualifying purchases exceed $4,090,000. Vehicles in this category, including cargo vans with permanent commercial modifications and heavy-duty work trucks, can potentially be fully expensed in the year of purchase.
