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.

Common questions
Can I deduct lease payments under the actual expense method?
Yes. If you lease a vehicle used for business, you can deduct the business-use percentage of your lease payments under the actual expense method. You may also need to include an "inclusion amount" that reduces the deduction for luxury vehicles — check IRS Publication 463 for the current tables.
Standard mileage rate vs actual expenses — which saves more?
It depends on your situation. The standard mileage rate is simpler and often better for fuel-efficient vehicles with high business miles. Actual expenses tend to save more if you have a newer or more expensive vehicle with high insurance, maintenance, or depreciation costs. Calculate both methods and compare before filing.
