Whether you’re self-employed or an employee, if you use a car for business, you get the benefit of tax deductions.

There are Two Choices for Claiming Deductions

  1. Deduct the actual business-related costs of gas, oil, lubrication, repairs, tires, supplies, parking, tolls, drivers’ salaries and depreciation.


  1. Use the standard mileage rate in 2017, and simply multiply 53.5 cents by the number of business miles traveled during the year. Your actual parking fees and tolls are deducted separately under this method.

Which Method is Better?

For some taxpayers, using the standard mileage rate produces a larger deduction. Others fare better tax-wise by deducting actual expenses.

Tip: The actual cost method allows you to claim accelerated depreciation on your car, subject to limits and restrictions not discussed here.

The standard mileage amount includes an allowance for depreciation. Opting for the standard mileage method allows you to bypass certain limits and restrictions and is simpler– but it’s often less advantageous in dollar terms.

Caution: The standard rate may understate your costs, especially if you use the car 100 percent for business, or close to that percentage.

Generally, the standard mileage method benefits taxpayers who have less expensive cars or who travel a large number of business miles but still have more personal miles than business miles.


Keep careful records of your travel expenses, and record your mileage. You can use a log book or, if you’re tech savvy, an app on your phone or tablet. Keeping track of the number of miles driven and the total amount you spent on the car is essential, because, if you don’t, your tax advisor won’t be able to determine which of the two options is more advantageous for you at tax time.

Furthermore, the tax law requires that you keep travel expense records and that you show business versus personal use on your tax return. If you use the actual cost method for your auto deductions, you must keep receipts.

Tip: Consider using a separate credit card for business to simplify your recordkeeping.

Tip: You can also deduct the interest you pay to finance a business-use car, if you’re self-employed.

Note: Self-employed individuals and employees who use their cars for business can deduct auto expenses if they either (1) don’t get reimbursed, or (2) are reimbursed under an employer’s “non-accountable” reimbursement plan. In the case of employees, expenses are deductible to the extent that auto expenses (together with other “miscellaneous itemized deductions”) exceed two percent of adjusted gross income.

Apps for Tracking Business Mileage

There are a number of phone applications (apps) that could help you track those pesky business miles. Most of these apps are useful for tracking and reporting expenses, mileage and billable time. They use GPS to track mileage, allow you to track receipts, choose the mileage type (business, charitable, medical, moving or personal), and produce formatted reports (IRS compliant HTML and CSV tax return reports) that are easy to generate and share with your CPA.
