Soldiers who serve in a combat zone can exclude certain pay from their taxable income. The Combat Zone Tax Exclusion (CZTE) is unlimited for enlisted members and warrant officers and is limited to the maximum enlisted pay amount, plus the amount of Hostile Fire Pay / Imminent Danger Pay payable to the officer for the qualifying month, for officers.

Army National Guard Soldiers on drill status are not eligible for CTZE. They are eligible when on federal active duty and serving in a combat zone.
