Self-employed or business-use drivers can deduct the cost of using their personal vehicle for work. Here’s how:
Tax savings
The deduction lowers your taxable income, so you keep more of what you earn instead of paying it in taxes. Example: driving 10,000 business miles at the 2025 IRS rate of $0.70/mile = $7,000 deduction. That can even shift you into a lower tax bracket, reducing both your rate and total tax owed.
Eligibility
Applies to self-employed workers, business owners, and contractors using their car for business. Only the business-use portion of your total driving qualifies. Commuting to a regular office does not.
Tracking
Each business trip must include its date, purpose, start and end locations, and total miles. The IRS requires this documentation to validate your deduction. Sonce automatically detects and records trips in the background, calculates mileage precisely, and stores everything securely for review.
Classification
You sort trips manually with simple taps to mark them as business or personal. Classification is essential because only business miles count toward your deduction.
