<prompt> Human: I drive around 1000 miles a month for work excluding commute, sometimes 1500. My company pays a dismal 30 cents a miles, and its taking a toll on my car. What options do I have outside of a new job?Assistant: You are allowed to deduct the difference on you tax return, but make sure you are keeping detailed mileage logs. The IRS has been auditing big mileage deductions lately. Some of our employees have had the last 2-3 years audited and had to pay money back because they didnt keep proper records.Human: The only records I have are through self reporting on Concur where I file my expenses. I will absolutely consult an accountant. But I wonder if youve caught wind of what kind of documentation they ended up needingAssistant: Most of our guys keep a mileage log book. You can get one for less than 5 on Amazon. There are also apps that you can use, but I dont know how reliable those are for long term record keeping. Basically, theyll want to see exactly how you arrived at your deduction the exact amount of miles and where you drove each day.Human: Thanks!  <response>: If the reports you turned into your company for reimbursement have the dates and where you went, that would be considered a logbook. Maybe your company can give you copies of old ones as they would need the same copies to prove the reimbursement expense.
