Military Tax-Free Zones: Locations, Pay Exclusions, and Filing

The military combat zone tax exclusion lets service members exclude military pay from federal income tax for any month they served at least one day in a presidentially designated combat zone or qualified hazardous duty area. Enlisted members and warrant officers can exclude every dollar; commissioned officers face a monthly cap tied to the top enlisted pay rate. The exclusion is authorized by 26 U.S.C. § 112 and is commonly called the CZTE.¹

Who Qualifies

Serve on active duty in a designated combat zone or qualified hazardous duty area (QHDA) for any part of a calendar month, and the whole month’s pay is eligible. One day counts. This catches many first-time deployers by surprise because a mid-month arrival or departure still qualifies the full month.¹

You don’t have to stand inside the zone itself. Service in a certified direct support area also qualifies, as long as the Department of Defense has designated your location for that combat zone. As of May 2025, DoD added Israel and Kenya to the direct support list.² Personnel receiving hostile fire pay or imminent danger pay under 37 U.S.C. § 310 for service outside the zone boundaries generally meet the qualifying-service test as well.¹

Current Combat Zones and Hazardous Duty Areas

The President designates combat zones by Executive Order, and they stay active until a later order ends them. As of 2026, the IRS recognizes four:³

Arabian Peninsula Area, effective January 17, 1991 under Executive Order 12744. Covers Iraq, Kuwait, Saudi Arabia, Oman, Bahrain, Qatar, the UAE, and adjacent waters including the Persian Gulf, Red Sea, and Gulf of Oman. Certified direct support countries include Jordan (2003), Lebanon (2015), and a portion of eastern Turkey (2016).
Kosovo Area, effective March 24, 1999 under Executive Order 13119. Covers the former Federal Republic of Yugoslavia (Serbia and Montenegro), Albania, Kosovo, and parts of the Adriatic and Ionian Seas north of the 39th parallel.
Afghanistan Area, effective September 19, 2001 under Executive Order 13239. Direct support countries include Jordan, Kyrgyzstan, Pakistan, Tajikistan, Uzbekistan, Yemen, Djibouti, Somalia, and Syria.
Sinai Peninsula, designated a Qualified Hazardous Duty Area under the Tax Cuts and Jobs Act. Same tax treatment as a presidentially designated combat zone.

The DoD’s direct support list can shift without a new Executive Order, so verify the current designation with your finance office or the DoD Financial Management Regulation before filing.²

What Pay Is Tax-Free

For each qualifying month, the exclusion covers:⁴

Your full month of basic pay.
Hostile fire pay and imminent danger pay, currently $225 per month.⁵
Reenlistment and continuation bonuses, if you signed the agreement while physically present in the zone.
Pay for accrued leave you earned during combat zone service, even if you sell it back after leaving the zone.
A proportional share of any military student loan repayment. If the repayment requires 12 months of service and six were in the zone, half is excludable.⁴

Two things the exclusion does not cover. Social Security and Medicare taxes are still withheld at the standard rates, which keeps your future Social Security earnings record intact.⁴ Military pensions and retirement pay are outside the exclusion entirely, no matter when the service was performed.¹

The Cap for Commissioned Officers

Enlisted members, warrant officers, and commissioned warrant officers have no dollar cap. Every dollar of qualifying compensation in a combat zone month is excluded.¹

Commissioned officers above the warrant level are limited to the “maximum enlisted amount”: the highest basic pay rate for an E-9 in the current pay tables plus any HFP or IDP received that month.¹ In 2026, the highest standard E-9 basic pay is $10,729.20 per month.⁶ Add the $225 HFP/IDP and the practical monthly cap is about $10,954.⁵ Anything above that is taxed normally.

Hospitalization for Combat Injuries

If you’re hospitalized for wounds, disease, or injury sustained while serving in the zone, the exclusion keeps running for every month that includes at least one day of that hospitalization. The hospital can be inside or outside the zone.⁴ The extension caps at two years after combatant activities in the zone terminate; pay for hospitalization beyond that window is not excluded.¹

Earned Income Tax Credit Election

Because excluded combat pay doesn’t appear in your taxable wages, your adjusted gross income drops. That can put the Earned Income Tax Credit in reach. The IRS lets you decide whether to include nontaxable combat pay as earned income for the EITC calculation.⁷

The election is all or nothing. Every dollar reported in Box 12, Code Q of your W-2 counts, or none does. When both spouses are service members filing jointly, each spouse elects independently, so four combinations are possible.⁷

Whether the election helps depends on where your income sits relative to the EITC phase-out. If non-combat income is well below the phase-out, adding combat pay can grow the credit. If it pushes you past the threshold, the credit shrinks or disappears. Run the return both ways and take the larger refund. BAH, BAS, and other nontaxable allowances can’t be added under this election.

Retirement Savings During Deployment

Thrift Savings Plan

Combat zone service unlocks the higher annual additions limit under IRC § 415(c) for the TSP. In 2026 that ceiling is $72,000 in total contributions from all sources, including any DoD matching. Participants aged 50 and older can add $8,000 in catch-up contributions, and those turning 60 through 63 in 2026 get a higher catch-up limit of $11,250.⁸⁹

Roth TSP is where the deployment advantage compounds. Combat pay is already tax-free, so Roth contributions made with that money go in untaxed and come out untaxed in retirement, along with decades of growth. Traditional TSP contributions from combat pay also go in untaxed, but their earnings become taxable when you withdraw them. During a deployment, Roth is almost always the stronger choice. If you later roll the TSP into an IRA, keep the tax-exempt contributions in a Roth account so they retain their tax-free status.

Individual Retirement Accounts

Combat pay counts as earned income for IRA purposes, so you can fund a Roth or traditional IRA even if excluded combat pay is your only income for the year.¹⁰ The 2026 IRA contribution limit is $7,500. Your deadline to contribute gets the same combat zone extension as your filing deadline.

The Filing Deadline Extension

Combat zone service triggers one of the most generous automatic extensions in the tax code. No paperwork required. It works in two parts.¹¹

First, the IRS disregards your entire time in the zone plus 180 days after you leave (or 180 days after continuous hospitalization for combat injuries ends, if later). Second, you get back the days that were left in your original deadline when you entered the zone.¹² Deploy on March 1 with a April 15 deadline, and you had 46 days remaining; your new deadline is your departure date plus 180 days plus those 46 days.¹³

The extension covers more than just filing. It also covers paying tax owed, filing refund claims, and contributing to an IRA. During the extension the IRS suspends collection, audit examinations, and the assessment of penalties and interest.¹²

Documents and Joint Filing

Your W-2 from the Defense Finance and Accounting Service is the core document. Box 12, Code Q reports total nontaxable combat pay for the year. That figure is not in Box 1 taxable wages; it’s there for informational purposes and to calculate credits like the EITC.⁴ Access it through myPay.¹⁴

Cross-check Code Q against your deployment orders and LES. If a qualifying month is missing, contact DFAS for a correction before filing. Errors either cost you tax or cost you a credit.

If your spouse is in a combat zone and can’t sign a joint return, you can sign for them without a power of attorney. Attach a signed statement explaining the combat zone service.¹¹ Or your spouse can file Form 2848 before deploying to grant formal power of attorney for tax matters. Either way preserves joint filing, which usually beats filing separately.

State Income Tax

Federal law governs the CZTE; state tax is a separate question. Nine states have no individual income tax at all. Among states that do tax income, most follow the federal exclusion and exempt combat zone pay, and a handful have their own combat-pay exemption statutes. Some mirror federal rules exactly; others set their own officer caps or narrow the exemption to specific duty statuses. Check your state of legal residence, not the state where you’re stationed, since military members are generally taxed by their home state. An installation legal assistance office or your state’s department of revenue can confirm the specifics.
