First, you may be eligible for a combat zone exclusion, which means some or all of your combat pay could be tax-free. However, you may choose instead to include tax-free combat pay in your earned income when you file your taxes to claim the Earned Income Tax Credit. This could get you a larger refund. So figure the credit with and without your combat pay and make the choice that’s best for you.
If you transfer to a new duty station, you may be able to deduct unreimbursed moving expenses. If the military reimburses you for those expenses, you don’t need to pay tax on that amount.
