The IRS standard mileage rate is a common benchmark, and many employers use it. Paying a different rate is allowed, and some states have their own reimbursement rules, which this calculator doesn’t model.
Keep a log for each trip with the date, destination, business purpose and miles. Rates are taken from the IRS standard mileage rates page and are reviewed whenever the IRS announces a change.
