Driving your personal vehicle for business purposes is a common and legitimate deduction for self-employed workers and business owners. You can either deduct your actual vehicle expenses based on the percentage of business use or use the standard mileage rate, which the IRS sets each year. The standard mileage rate for 2024 is 67 cents per mile for business driving. Commuting from your home to your regular office does not count as business mileage. Keeping a mileage log with the date, destination, and purpose of each business trip is important because the IRS considers vehicle deductions a common area of abuse.
