Military Tax Filing Benefits: Combat Pay, Extensions, and PCS Moves

Military tax filing benefits include a full or partial exclusion of combat pay, automatic deadline extensions while deployed, a moving expense deduction that civilians lost after 2017, a pause on the home-sale capital gains clock during extended duty, state residency protections for service members and spouses, and special retirement account and credit rules built around military pay. Some apply automatically; others require an election you have to know to make.

Combat Zone Pay Exclusion

If you serve in a combat zone designated by the President, military pay earned during any month you spend there is excluded from gross income.1Office of the Law Revision Counsel. 26 U.S.C. 112 – Certain Combat Zone Compensation of Members of the Armed Forces One day in the zone counts the whole month. The exclusion also covers months you spend hospitalized for wounds or injuries from the zone, up to two years after combatant activities end.

For enlisted personnel and warrant officers, the exclusion has no dollar cap. Basic pay, reenlistment bonuses, and pay for accrued leave earned in qualifying months all stay out of gross income and won’t appear as taxable wages on your W-2.

Commissioned officers face a monthly ceiling equal to the highest rate of enlisted basic pay plus any hostile fire or imminent danger pay for that month.1Office of the Law Revision Counsel. 26 U.S.C. 112 – Certain Combat Zone Compensation of Members of the Armed Forces For 2026 that works out to roughly $11,391.90 per month.2MyArmyBenefits. Combat Zone Tax Exclusion (CZTE) Anything above the ceiling is taxed normally.

Currently designated zones include the Arabian Peninsula area, the Afghanistan area, the Kosovo area, and the Sinai Peninsula.3Internal Revenue Service. Combat Zones Approved for Tax Benefits To qualify, you must serve in the zone itself, in a direct support area designated by the Department of Defense, or in a qualified hazardous duty area, and you must receive hostile fire or imminent danger pay.

Putting Tax-Free Combat Pay Into a Roth Account

Combat pay that never enters your gross income can still be contributed to a Roth TSP or Roth IRA. The result is unusual: the money wasn’t taxed going in, and Roth withdrawals aren’t taxed coming out. Both ends escape taxation.

For 2026, the TSP elective deferral limit is $24,500, with an annual additions limit of $72,000 that includes all employee and employer contributions.4Thrift Savings Plan. Contribution Limits Service members contributing combat pay can go up to the annual additions limit, not just the standard deferral cap. Contributions above $24,500 are routed automatically to a traditional TSP balance. If you later roll your TSP out, keep the tax-exempt portion in a Roth account so it stays tax-free.

You can also contribute combat pay to a Roth IRA, up to $7,500 for 2026.5Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Excluded combat pay would otherwise leave you with no earned income for IRA purposes, but the tax code specifically allows it to count as compensation for IRA eligibility.

Filing and Payment Extensions While Deployed

When you’re deployed to a combat zone, the IRS automatically pauses your deadlines for filing returns, paying tax, and submitting refund claims. No form or request is required; the Department of Defense notifies the IRS.6Office of the Law Revision Counsel. 26 U.S.C. 7508 – Time for Performing Certain Acts Postponed by Reason of Service in Combat Zone or Contingency Operation The pause runs for your entire time in the zone, plus any continuous hospitalization for injuries sustained there, plus 180 days after you leave the zone or are released.

The extension also covers your spouse, even on a separate return.7Internal Revenue Service. Extension of Deadlines – Combat Zone Service Two limits apply: the spouse’s extension ends if you’re hospitalized stateside for combat zone injuries, and it doesn’t apply for a tax year that begins more than two years after the combat zone designation ends.

A smaller extension exists for service members stationed outside the United States and Puerto Rico who aren’t in a combat zone. If you’re overseas on the regular April deadline, the due date automatically becomes June 15.8Internal Revenue Service. U.S. Citizens and Resident Aliens Abroad – Automatic 2-Month Extension of Time to File Late-filing and late-payment penalties are waived during that window, but interest still accrues from April on any unpaid balance.

Moving Expenses Under PCS Orders

The moving expense deduction was eliminated for civilians after 2017 but preserved for active-duty members moving under permanent change of station orders. Unreimbursed moving costs are deductible.9Internal Revenue Service. Topic No. 455, Moving Expenses for Members of the Armed Forces and the Intelligence Community

Qualifying moves include your first move to active duty, moves between permanent duty stations, and the move home after separation (within one year, or within the time allowed by the Joint Travel Regulations).10Internal Revenue Service. Instructions for Form 3903 (Moving Expenses) Deductible costs include hauling household goods, packing, crating, in-transit storage, insurance, and travel to your new home including lodging along the way. Meals during the move don’t count. Neither do house-hunting trips, lease-breaking fees, or costs of buying or selling a home.

If you drive your own vehicle, the 2026 mileage rate for military moves is 20.5 cents per mile, plus parking and tolls.11Internal Revenue Service. IRS Sets 2026 Business Standard Mileage Rate at 72.5 Cents Per Mile, Up 2.5 Cents Report the deduction on Form 3903; it reduces adjusted gross income directly whether or not you itemize. One catch: if reimbursements exceed actual expenses, the excess goes into gross income.

State Residency for Service Members and Spouses

Under the Servicemembers Civil Relief Act, you don’t gain or lose a state of residence for tax purposes just because military orders send you somewhere. Your military pay can only be taxed by your state of legal domicile, not the state where you’re stationed.12Office of the Law Revision Counsel. 50 U.S.C. 4001 – Residence for Tax Purposes

Spouses have parallel protection. For any tax year, a military couple can elect to use any of three domiciles for state income tax: the service member’s domicile, the spouse’s domicile, or the service member’s permanent duty station.12Office of the Law Revision Counsel. 50 U.S.C. 4001 – Residence for Tax Purposes A spouse can claim the service member’s home state even without ever having lived there, which matters when the family is stationed in a high-tax state but the legal domicile is a state with no income tax.

The protection covers wages and salary. Rental income from property in another state, or business income tied to a specific state, may still be taxable where it’s generated. States vary in how readily they recognize the election, so you may still need to file in your duty-station state to explain why you owe nothing. Keep the domicile election and the service member’s orders on file.

Home Sale Capital Gains Exclusion

The standard rule lets you exclude up to $250,000 in gain, or $500,000 for married couples filing jointly, on the sale of a primary residence, if you owned and lived in the home for at least two of the five years before the sale. Frequent PCS moves make that test hard to meet.

The military fix suspends the five-year clock for up to 10 years while you or your spouse is on qualified official extended duty.13Office of the Law Revision Counsel. 26 U.S.C. 121 – Exclusion of Gain From Sale of Principal Residence That stretches the ownership-and-use window to as long as 15 years. You must elect the treatment, and only one property at a time qualifies.

Qualified official extended duty means active duty for more than 90 days or an indefinite period, at a station at least 50 miles from the property, or while living in government quarters under orders.13Office of the Law Revision Counsel. 26 U.S.C. 121 – Exclusion of Gain From Sale of Principal Residence It applies to uniformed services members, the Foreign Service, and intelligence community employees. Buy a home at your first duty station, live in it a year, spend the next 12 at other posts, and the suspension can still preserve your exclusion if you sell within the 15-year window.

Reservist Travel Deduction

Guard and Reserve members who travel long distances for drills or training can deduct those costs without itemizing. Your service location must be more than 100 miles from home.14Office of the Law Revision Counsel. 26 U.S.C. 62 – Adjusted Gross Income Defined The deduction covers transportation, lodging, and meals during the service period, capped at the federal per diem rates for the training location rather than what you actually spent.

Compute the amount on Form 2106 and carry the reservist portion to Schedule 1 of Form 1040, line 12.15Internal Revenue Service. Instructions for Form 2106 Because it’s above-the-line, it reduces adjusted gross income directly, which can also improve eligibility for other tax benefits that phase out at higher income. Keep travel orders and receipts for anything above the per diem rate.

Earned Income Tax Credit Election

The Earned Income Tax Credit lets military filers choose to include nontaxable combat pay as earned income for the credit calculation.16Internal Revenue Service. Military and Clergy Rules for the Earned Income Tax Credit For families whose taxable income is low because most pay came from a combat zone, that election can substantially increase the credit.

For 2026, the maximum EITC reaches $8,231 for taxpayers with three or more qualifying children, and $664 for filers with no children. The credit phases in with earned income, tops out, then phases out. Including combat pay must be all or nothing.

The election isn’t always worth making. If adding combat pay pushes you past the phase-out threshold, the credit shrinks. The only reliable way to know is to run the numbers both ways. Free military tax software does this comparison automatically.

Early Retirement Withdrawal Penalty Waiver for Reservists

Reservists called to active duty for more than 179 days or an indefinite period can withdraw from an IRA, 401(k), or 403(b) without the 10% early withdrawal penalty that normally applies before age 59½.17Internal Revenue Service. Publication 3 (2025), Armed Forces Tax Guide The distribution has to occur between the call-up order and the end of active duty. Regular income tax still applies to the withdrawal.

You can also repay the distribution to an IRA after active duty ends, effectively treating it as a temporary loan from retirement savings. The repayment goes to an IRA (not back to the 401(k) or 403(b) it came from) and doesn’t count against the annual contribution limit.

Free Tax Help and Filing While Deployed

MilTax, offered through Military OneSource, provides free tax software and e-filing built for military returns, with no income limits. It handles combat pay exclusions, multi-state filing, and PCS-related deductions, and eligible users can file a federal return plus up to three state returns at no cost.18Internal Revenue Service. Free Online Tax Help for Military Members and Their Families Tax consultants trained in military issues are also available.

The Volunteer Income Tax Assistance program runs on most major installations worldwide, staffed by certified volunteers who know deployment documentation and military pay codes. That’s especially helpful with mid-year PCS moves or transitions between active duty and reserve status.

Signing a Return While You’re Overseas

If you’re deployed and can’t sign your return, a spouse or another designated person can sign under a power of attorney. The IRS allows this when the taxpayer has been continuously outside the United States for at least 60 days before the filing deadline.19Internal Revenue Service. Instructions for Form 2848 Complete Form 2848 before deploying, and check the box authorizing the agent to sign a return. Setting this up in advance avoids trying to execute paperwork from a combat zone.
