I am classified as a minister, but recently took a new position as Coordinator of an Association of churches. I receive a salary for the administrative part of this job. However, my employer does not reimburse me for travel and speaking at other churches. I receive reimbursement and honorarium from these churches. I have one automobile that I use for both these business trips and for personal use. Can I deduct the IRS allowable mileage of 50.5 cents a mile for these trips with the car? And if so what kind of records do I need to keep?
