Your automobile may provide you with several tax deductions that may lower your income tax. As with all deductions, it's important to maintain accurate records of your expenses.
Business
You cannot deduct commuting mileage - that is, mileage from your home to your regular job.
However, if you are self-employed and maintain an eligible office in your home, you can deduct the mileage to and from your client's or customer's place of business, as well as between jobs.
