Generally, you can use the "standard meal allowance" method as an alternative to the actual cost method. It allows you to use a set amount for your daily meals and incidental expenses (M&IE), instead of keeping records of your actual costs. The set amount varies depending on where and when you travel. In this publication, "standard meal allowance" refers to the federal rate for M&IE, discussed later under Amount of standard meal allowance . If you use the standard meal allowance, you still must keep records to prove the time, place, and business purpose of your travel. See the recordkeeping rules for travel in chapter 5.
