Yes, Military personnel working in combat zones can defer filing and paying their taxes until 180 days after the end of their active service in the zone.
If you are claiming the 180-day filing and paying extension for combat zone personnel, you can either contact the IRS to let it know of your status at combatzone@irs.gov, call the IRS, or respond to a notice of action from them.
Please see How do I file an IRS extension (Form 4868), Extensions for Military Personnel and IRS FAQ Extension of Deadlines — Combat Zone Service for details.
