I drove 27,000 miles for work last year. I live 3 hours from our home office, so I do not conduct my business from the office. I am in the healthcare field, and am a contracted employee. We carry our necessary equipment and supplies in our car at all times. The closest hospital I travel to us is 100 miles from my home. There is nothing in box 12 under code L. My company does not reimburse me for mileage, though I am paid a certain travel fee that gets taxed as regular income. Can you tell me if I am able to deduct the mileage I drove, and if so, what are the rules I need to follow?
