Serve · For members of the Armed Forces and their families
Military Desk
Military service scrambles everything the tax calendar assumes: you are ordered away during filing season, paid in a war zone, married across three duty stations, and told to sell a house you lived in for fourteen months. The tax code answers with a set of standing orders of its own — deadlines that wait for you, pay the Treasury may not touch, a choice of which state gets to call you a resident, and a deferral for the season when service itself breaks the budget. Almost all of it is automatic or elective, and almost none of it is announced to the people it protects. This desk is the announcement.

The combat-zone clock — §7508
The strongest deadline rule in the tax code belongs to the people least able to meet a deadline. If you serve in a combat zone or a designated contingency operation, the time you have to file, pay, claim, and answer the IRS does not merely pause while you are gone — it is rebuilt when you come home, by this formula:
Your service + 180 days + the days you had left
Your deadline becomes 180 days after the later of (a) your last day in the combat zone (or the last day the area qualifies as one) or (b) the last day of any continuous qualified hospitalization for injuries from that service — plus whatever days remained in the period you originally had to act when you entered the zone.
The IRS's own worked example: a member who entered the zone on March 1 with an April 15 filing deadline had 46 days left in the filing period when he entered. After his last day in the zone, his deadline is 180 + 46 = 226 days later — and during that whole extension, assessment and collection deadlines are extended too, and no interest or penalties are charged for the delay.
The same clock covers filing any return, paying any tax, filing a refund claim, petitioning the Tax Court, and making an IRA contribution. It is automatic in law — no form requests it — but tell the IRS you deployed if a notice arrives anyway (see the fourth card below).

Who the clock protects
Members of the Armed Forces serving in a combat zone or in a contingency operation designated by the Secretary of Defense. Also covered: members serving outside the zone in direct support of combat-zone operations who receive hostile fire or imminent danger pay as certified by the Department of Defense — and, inside the zone, the people serving in support of the Armed Forces: merchant marines aboard vessels under the DoD's operational control, Red Cross personnel, accredited correspondents, and civilians acting under the direction of the Armed Forces. A defense contractor working a private project in the same geography is not covered; support of the Armed Forces is the line.
Authority: IRC §7508; IRS, “Extension of deadlines — Combat zone service,” A16–A17
Hospitalization stretches the clock — with one border
If you are hospitalized for wounds, disease, or injury from your combat-zone service, the deadline runs from the end of your continuous qualified hospitalization instead of your last day in the zone. Hospitalization outside the United States counts in full. Hospitalization inside the United States counts too — up to five years of it. One fine-print warning from Publication 3: for the IRS's own collection deadlines, the hospitalization addition is figured without the continuous-hospitalization rule (a 2015 statute, P.L. 114-113 §309) — if a collection notice arrives while you are hospitalized, take it to your installation legal assistance office rather than assuming it is wrong or assuming it is right.
Authority: IRC §7508(a); Pub. 3 (2025), “How Much Extra Time Do These Extensions Give Me?”
Your spouse shares the deadline — joint or separate
The extension belongs to the spouse too, whether you file jointly or on separate returns: the spouse keeping the household gets the same filing and payment deadline as the member in the zone, and dependent children's returns ride on the joint deadline as well. Two exceptions, both from the IRS's own Q&A: the extension does not extend to the spouse on account of the member's hospitalization inside the United States, and it does not apply to a tax year beginning more than two years after the combat zone designation terminates.
Authority: IRS, “Extension of deadlines — Combat zone service,” A20–A22
The IRS's clocks pause too — and so do your installment payments
The postponement is not one-sided grace; it binds the government as well. During the extension period the IRS's deadlines for assessment and collection are extended, installment-agreement payments on pre-service balances are paused for the service period plus 180 days, and no interest or penalties are charged for the delay. If the IRS moves against you anyway — an examination notice, a collection letter — it is usually because its computers do not know you deployed: members can self-identify their combat-zone status to the IRS (Publication 3 explains how), and a legal assistance office can get the account marked.

Combat pay — §112
Enlisted and warrant officers: the whole month, tax-free
Serve one day of a month in a combat zone and that month's military pay is excluded from federal income tax — all of it, for enlisted members, warrant officers, and commissioned warrant officers: basic pay, imminent danger and hostile fire pay, reenlistment and continuation bonuses signed for in the zone, leave sold that was earned in the zone, even the combat-zone share of student-loan repayments. The exclusion is automatic — your service certifies it by leaving the pay off the taxable wages on your W-2 (the excluded amount shows in box 12, code Q). If your W-2 shows full unadjusted pay anyway, the correction belongs to your military pay office, not to your return. Two honest limits: the pay is still subject to Social Security and Medicare taxes, and pay received for hospitalization that runs more than two years past your last month in the zone stops being excludable.
Authority: IRC §112; IRS, “Tax exclusion for combat service”
Commissioned officers: the same exclusion, with a ceiling
Commissioned officers exclude combat-zone pay on the same terms, up to a monthly ceiling: the highest rate of enlisted basic pay, plus the imminent danger or hostile fire pay for that month. Pay above the ceiling is ordinary taxable wages. The IRS publishes the mechanism rather than a standing dollar figure — the ceiling moves with the pay tables — so this desk prints the formula and not a number: compute yours from the current pay tables or Publication 3's current edition before you rely on it.

Tax-free pay still builds a retirement: the IRA door
Excluded is not erased. Nontaxable combat pay counts as compensation for IRA purposes, so a deployment year is not a lost savings year — and routed into a Roth IRA, money that was never taxed going in can come out tax-free in retirement, one of the few genuinely double-tax-free paths in the code. The combat-zone clock helps here too: your deadline to make a prior-year IRA contribution is the extended filing deadline, not April 15.
Authority: Pub. 590-A, “What Is Compensation?”; IRC §7508 (IRA contributions among the postponed acts); IRS, “Extension of deadlines,” A26
Combat pay and the Earned Income Credit: a choice, not a rule — run it both ways
Nontaxable combat pay does not have to count as earned income for the Earned Income Tax Credit — but you may elect to count it. The election is all-or-nothing per person (include all of your nontaxable combat pay, or none), each spouse elects separately, and the amount is the figure on your W-2, box 12, code Q. It is reported as the nontaxable combat pay election on Form 1040, line 1i.
Why it cuts both ways: the EITC grows with earned income on the way up and shrinks with it on the way down. A junior member with little taxable pay may gain hundreds by electing; a member whose household already sits in the phase-out range loses credit by adding tax-free pay to the measure. This is not theory — Publication 3 works the example: a couple adding $35,000 of nontaxable combat pay computed a $2,242 credit, against $2,389 without the election, and chose not to elect. Compute it both ways, every year you have combat pay. The platform's Refund Estimator cannot make this judgment for you — it is exactly the kind of fork a credentialed pro or MilTax (below) earns its keep on.

Whose state taxes you — MSRRA and the three doors
Federal law decides your federal return; a separate layer of federal law — the Servicemembers Civil Relief Act and its amendments — decides which state may tax a military family. The rules grew in three steps, and the third one is less than four years old:
The servicemember's home state travels with them
A servicemember does not gain or lose a state of legal residence by being stationed somewhere under orders. Military pay is taxed by the home state — the state of legal residence — not by the duty state, however long the assignment runs. Everything below is about the person married to that servicemember, whose civilian life does not come with the same built-in protection.
The spouse keeps home, if home is why they can leave
The Military Spouses Residency Relief Act extended the same shelter to spouses: a spouse who is in a duty state solely to be with their servicemember, who is there under military orders, does not become a tax resident of that state by living and working in it. The duty state cannot tax the spouse's income from services performed there; the spouse's wages belong, for tax purposes, to the state of domicile they kept. The conditions are the statute's, all three: married to the servicemember, the servicemember present under orders, and the spouse present solely to be with them.
Or simply elect the servicemember's state
The original act effectively required the couple to share one domicile, which broke for couples who married across state lines. The Veterans Benefits and Transition Act of 2018 removed the friction: a spouse may elect to use the servicemember's state of residence for tax purposes — and for voting — even if the spouse has never lived in that state, for any tax year from 2018 onward.
Today the couple chooses among three states
The Veterans Auto and Education Improvement Act of 2022 opened the choice fully. For any taxable year of the marriage, the servicemember and the spouse may each elect to be taxed as a resident of any one of: (1) the servicemember's state of residence, (2) the spouse's state of residence, or (3) the state of the servicemember's permanent duty station. The election is made year by year as assignments change. Two boundaries keep it honest: the shield covers income from services — rent from a house you own in the duty state, and other property or investment income sourced there, still belongs to that state — and an election chooses which state taxes you, not whether you are taxed; ignore the chosen state's filing duties and its penalties apply like anyone's.
Authority: 50 U.S.C. §4001, as amended by the Military Spouses Residency Relief Act (2009), the Veterans Benefits and Transition Act of 2018 §302, and the Veterans Auto and Education Improvement Act of 2022. State filing mechanics — withholding certificates, each state's forms — are set by the states; this desk teaches the federal frame the states must honor.
If service itself breaks the budget — the SCRA deferral
A deferral written for the member whose pay changed, not the member who deployed
Separate from the combat-zone clock — and available to a member who never leaves the United States — the Servicemembers Civil Relief Act lets a member of the Armed Forces (and commissioned officers of the Public Health Service and NOAA Corps) defer income tax that becomes due before or during military service, when the member notifies the IRS that their ability to pay has been materially affected by the military service itself: the reservist called up to a fraction of a civilian salary is the case this was written for.
The terms, exactly as Publication 3 gives them: you may take up to 180 days after termination or release from military service to pay; pay in full by the end of that period and no interest or penalties are charged for it. The request is made in writing to the IRS office that sent you the payment notice (or the office holding your installment agreement), with your income before and during service, your rank, and your service dates — a copy of your orders helps. Three edges: the deferral does not cover the employee share of Social Security and Medicare taxes; the IRS's collection clock is suspended during your service plus 270 days; and if the deferral is denied, interest on the tax during active service is capped at 6% per year.

The house and the move
Orders pause the five-year clock on your home-sale exclusion
The home-sale exclusion asks for two years of ownership and two years of use inside the five years before the sale — a test written for people who stay put. A member on qualified official extended duty may elect to suspend that five-year clock for up to 10 years: duty under orders for more than 90 days (or an indefinite period) at a station at least 50 miles from the home, or living in government housing under orders. Suspended, the window stretches to as much as fifteen years — a home lived in for two years, left for a decade of orders, and then sold can still qualify in full. The suspension covers one property at a time, and the same rule serves the Foreign Service and the intelligence community. The Home-Buying & Deductions Coach carries the exclusion itself.
Authority: IRC §121(d)(9); Pub. 523, “Suspension of the Five-Year Test Period”
The last moving deduction standing belongs to you
Before 2018, anyone who moved for work could deduct the cost. The TCJA suspended that deduction for civilians through 2025, keeping one exception — and the 2025 law then made the civilian suspension permanent. The exception stands: a member of the Armed Forces on active duty who moves under a military order for a permanent change of station may still deduct the reasonable unreimbursed cost of moving themselves and their household. New for 2026, employees and new appointees of the intelligence community who relocate for a change in assignment receive the same treatment. If it was not a PCS — a move you chose, however sensible — the deduction is not there.
