Allowable expenses include expenses for overnight transportation, meals, and lodging. The amount of the allowable expenses cannot exceed the amount the federal government pays its employees for travel expenses. Although combat pay is not included in income when calculating your federal income tax, you have the option of including combat pay as earned income when calculating the Earned Income Credit. You should calculate your return both ways (including and not including combat pay as earned income for Earned Income Credit purposes) to determine which way gives you the more advantageous result.
