Vehicle Tax Deduction: How It Saves You $5,000-$30,000 in 2026
Business vehicles qualify for significant tax deductions through Section 179 expensing and bonus depreciation. For heavy vehicles (over 6,000 lbs GVWR, think SUVs like Escalade, Range Rover, GLE, X5, Model X), Section 179 allows you to deduct up to $30,500 in the first year, with the remainder eligible for bonus depreciation. Lighter vehicles have lower limits but still offer substantial deductions for business use.
Who Qualifies
- Use the vehicle more than 50% for business
- Own or lease the vehicle (not personal use only)
- Business owners, self-employed, and employees with unreimbursed business vehicle expenses
Who does NOT qualify
- Vehicle used primarily for personal purposes (under 50% business use)
- Employees whose employer reimburses vehicle expenses
- Commuting is NOT business use
How the Math Works
Section 179 deduction: $30,500. Remaining basis eligible for bonus depreciation. Total first-year deduction: ~$60,000 (80% business use). Business-use percentage applies.
At a 37% marginal rate, $60,000 × 37% = $22,200 in year-one tax savings.
Legal Basis & IRC Citations

Frequently Asked Questions
What is the 6,000 lb rule?
Vehicles with a Gross Vehicle Weight Rating (GVWR) over 6,000 lbs are exempt from the luxury vehicle depreciation caps under §280F. This means you can deduct significantly more in year one, up to $30,500 under §179 plus additional bonus depreciation on the remaining basis.
What counts as business use?
Driving to client meetings, job sites, between offices, to the airport for business travel, and similar business purposes. Commuting from home to your regular office does NOT count. Keep a mileage log.
Can I deduct a leased vehicle?
Yes. You can deduct lease payments proportional to business use. Alternatively, you can use the standard mileage rate ($0.70/mile in 2026) if simpler. Your CPA can determine which method saves more.
