Vehicle Actual Expenses Tax Deduction: Is It Deductible for Self-Employed?

Schedule C
Car and truck expenses
Category
If you use a vehicle for your self-employed business, you can deduct actual expenses like gas, oil, repairs, insurance, and registration on Schedule C. Unlike the standard mileage rate, the actual expense method lets you deduct the real costs you pay—but only the percentage that relates to business use. Tracking these expenses requires maintaining a detailed mileage log to prove your business-to-personal use ratio.
Who qualifies?
Self-employed individuals, sole proprietors, and single-member LLC owners who use a vehicle for business purposes can claim this deduction. You must be able to document business use with a mileage log and separate business expenses from personal use.
How to claim it
- 1 Track all vehicle expenses (fuel, maintenance, insurance, registration, repairs, tires) throughout the tax year with receipts.
- 2 Keep a mileage log noting business miles driven, personal miles, and total miles to calculate your business use percentage.
- 3 Calculate deductible expenses by multiplying total costs by your business use percentage (e.g., 70% business use = 70% of expenses deductible).
- 4 Report the total business portion on Schedule C, Line 9 (Car and truck expenses).
Pro tip
Use a mileage tracking app like MileIQ or Stride Health to automatically log business miles in real-time—handwritten logs created months later are more likely to trigger IRS scrutiny. Snap photos of receipts immediately and store them with the corresponding mileage entry for ironclad documentation.
