I recently read an article about Retail Merchandisers claiming more miles than they actually drove due to the rising cost of gasoline. This issue has come up time and time again over the years in all industries where mileage reimbursement part of the job. In a perfect world the company would recognize that gasoline is a big expense for their employees and increase the reimbursement to properly compensate. However it is probably cheaper to know that a certain percentage of millage claims are always going to be inaccurate regardless if the reimbursement is “Fair”. I am not an expert on the subject, but I believe that if your company’s reimbursement rate is less than the IRS rate you may write off the difference on your taxes. (DISCLAIMER I AM NOT A CPA) I would be sure keep detailed accurate records and have a conversation with your accountant. In any case when you are given asked to report millage and other expenses for reimbursement it comes down to your personal morals and ethics. These are going to vary from person to person and will be justified in many different ways. Personally I would prefer not to have an embarrassing conversation with a supervisor regarding a few dollars.
