Business Vehicle: Buy vs. Lease Tax Comparison
The buy vs. lease decision for a business vehicle is both a financial decision and a tax decision. The tax treatment differs significantly depending on the vehicle’s weight. For passenger cars and light trucks under 6,000 lbs GVWR, luxury auto depreciation limits (IRC 280F) cap the annual depreciation deduction, making the tax benefit similar for buying and leasing. For SUVs, trucks, and vans over 6,000 lbs GVWR, there are no luxury limits, and the entire cost can be depreciated in Year 1 under bonus depreciation or Section 179 (Section 179 is capped at $30,500 for SUVs). This makes purchasing far more tax-advantageous for heavy vehicles.
Buy vs. lease tax comparison:
Purchasing (depreciation method):
- Passenger vehicles (under 6,000 lbs GVWR): subject to luxury auto limits
- 2024 limits (with bonus depreciation): Year 1 $20,500, Year 2 $19,500, Year 3 $11,700, Year 4+ $6,960
- Total depreciation over 6 years: approximately $65,620 (even for a car costing $80,000+)
- SUVs, trucks, vans (over 6,000 lbs GVWR): NO luxury auto limits
- Bonus depreciation: 100% of cost in Year 1 (no dollar limit)
- Section 179: limited to $30,500 for SUVs (defined as 4-wheeled passenger vehicles between 6,000-14,000 lbs GVWR)
- Section 179 for trucks/vans: full $2,500,000 limit (no SUV cap)
- Business use percentage: depreciation is multiplied by business use percentage
Leasing:
- The full lease payment is deductible (multiplied by business use percentage)
- No depreciation (you don’t own the asset)
- Luxury vehicles: an “inclusion amount” reduces the deduction (Table in Rev. Proc. published annually)
- The inclusion amount is designed to put lessees in a similar tax position as buyers subject to luxury limits
- Over 6,000 lbs: no inclusion amount
Standard mileage rate (alternative to both):
- 2025 rate: 70 cents per mile
- Cannot use if you claimed bonus depreciation or Section 179 on the vehicle in a prior year
- Cannot use for 5+ vehicles operated simultaneously (fleet rule)
- Includes depreciation component, so no additional depreciation deduction
- Often simpler but not always the best tax result
Vehicles over 6,000 lbs GVWR (common examples):
- Ford F-150 (most configurations)
- Chevrolet Silverado 1500 (most configurations)
- RAM 1500 (most configurations)
- Toyota Tundra
- Ford Explorer (certain trims)
- Chevrolet Tahoe / Suburban
- GMC Yukon
- Jeep Grand Cherokee (certain trims)
- Ford Transit / E-Series
- Mercedes-Benz GLS
- BMW X5 / X7
- Tesla Model X
Check the GVWR on the driver’s side door jamb sticker. It must be OVER 6,000 lbs, not equal to.
What’s the tax difference between buying and leasing?
Should I use the standard mileage rate or actual expenses?
The standard mileage rate is simpler and often better for newer vehicles with low operating costs. The actual expense method (gas, insurance, repairs, depreciation) is typically better for older or expensive-to-operate vehicles and for heavy trucks not subject to the luxury auto limits under IRC 280F. You must choose the standard rate in the first year you use the vehicle for business; if you start with actual expenses, you can never switch to the standard rate for that vehicle. For most owners driving 10,000-20,000 business miles, the standard rate produces $7,000-$14,000 in deductions with minimal recordkeeping.
What records do I need for the vehicle deduction?
The IRS requires a contemporaneous mileage log for every vehicle deduction, whether you use the standard rate or actual expenses. The log must record the date, destination, business purpose, and miles driven for each business trip. Commuting from home to a regular office does NOT count as business mileage, but driving between business locations, to temporary work sites, or to client appointments does. Apps like MileIQ or Everlance automate tracking. Without a log, the entire vehicle deduction can be disallowed on audit regardless of how many miles were actually driven for business. Bank and credit card records for gas alone do not satisfy the substantiation requirements.
