Section 179 Business Tax Savings

Section 179 Vehicle Tax Deductions for 2026

Buying a work truck, van, or SUV for your business? Section 179 can let you write off all or part of the vehicle's cost in the same year you put it to work, rather than depreciating it over several years. How much you can deduct depends on the vehicle's type, its GVWR (gross vehicle weight rating), and how much you use it for business.

How Section 179 Works for Business Vehicles in 2026

Start by identifying which category your vehicle falls into, based on GVWR and design, and confirm your business-use percentage. With those two answers, you can estimate your first-year write-off and plan your purchase around it. You can find the GVWR on the label inside the driver's door or in the vehicle specifications.

Capped Deductions: SUVs, Cars & Light Trucks

     
  • Passenger SUVs (6,001-14,000 lbs GVWR): Section 179 capped at $32,000
    •  
  • Example: On a $75,000 SUV, deduct $32,000 under Section 179; the remaining $43,000 may qualify for bonus depreciation
    •  
  • Cars and light trucks (6,000 lbs GVWR or less): Combined Section 179, bonus, and regular depreciation are capped by Section 280F
    •  
  • Section 280F limits are reduced when business use is under 100%

Business-Use Requirements and Financing

     
  • More than 50% business use: Exactly 50% does not qualify. Keep mileage or usage logs.
    •  
  • Income limitation: The deduction cannot exceed your business income for the year; unused amounts generally carry forward.
    •  
  • New or used: Both qualify if the vehicle is new to you and bought in an arm's-length transaction.
    •  
  • Financing qualifies: Purchases and non-tax capital leases can qualify, so you can claim the deduction while spreading payments over time. Operating leases generally do not.
    •  
  • Recapture risk: If business use falls to 50% or less during the vehicle's 5-year class life, part of the deduction may be recaptured.

Common Mistakes to Avoid

     
  • Overstating business use: Do not claim 100% if the vehicle is also used for personal errands. Keep accurate logs.
    •  
  • Misreading the SUV rules: Exceeding 6,000 lbs GVWR does not guarantee a full deduction for a passenger-type vehicle.
    •  
  • Titling in a personal name: Title the vehicle in your business name to avoid compliance issues.
    •  
  • Missing the deadline: The vehicle must be placed in service by December 31, 2026 for calendar-year taxpayers.
    •  
  • Ignoring state rules: Some states do not fully follow federal Section 179 or bonus depreciation rules.
