Military tax deductions and exclusions: the documents service members need
By Arthur Teboul, DokuTrak · Published
In brief
The main tax deductions for military members are PCS moving costs on Form 3903 and reservist travel more than 100 miles from home (IRS Publication 3). The bigger savings are exclusions: combat zone pay and most allowances never reach taxable income, so the documents that prove them matter most.

Military tax deductions start with what is left out of income
Service members save more from exclusions than from deductions. An exclusion is pay that never counts as income, so it does not need a receipt or a line on Schedule A. Housing and subsistence allowances, uniform allowances and moving allowances all appear among the items Publication 3 excludes (IRS Publication 3).
Your Form W-2 from DFAS already leaves those amounts out of Box 1. That makes the W-2 the core document, and the December Leave and Earnings Statement the check on it. Compare the year-end LES with the W-2 before you file, for example to catch state tax withheld for the wrong state.
True deductions are few. Active-duty members can deduct moving costs for a PCS move, and reservists can deduct travel to duty far from home (IRS Publication 3). Almost every other job cost, such as uniforms you buy yourself, is barred on the federal return (26 U.S.C. 67).
| Item | Tax treatment | Document that proves it |
|---|---|---|
| Combat zone pay | Excluded from income (IRS Publication 3) | Form W-2, Box 12 code Q, and deployment orders |
| BAH, BAS, uniform allowance | Excluded from income (IRS Publication 3) | Leave and Earnings Statement |
| PCS move costs not reimbursed | Deduction on Form 3903 (IRS Publication 3) | PCS orders, receipts, travel voucher |
| Reservist travel over 100 miles (IRS Publication 3) | Deduction via Form 2106 (IRS Publication 3) | Drill orders, lodging and travel receipts |
| Uniforms bought yourself | Not deductible federally (26 U.S.C. 67) | Keep receipts only for a state that allows them |
Combat zone pay: the exclusion, the officer limit and the EIC choice
Enlisted members and warrant officers exclude active duty pay for any month they served in a combat zone (IRS Publication 3). Commissioned officers have a cap: the highest rate of enlisted pay plus imminent danger pay for each month (IRS Publication 3). For 2025, the IRS puts that cap at $10,983 a month (IRS Publication 3).
The excluded amount still shows on your W-2, in Box 12 with code Q (IRS Publication 3). You can choose to count it as earned income for the earned income credit, and that choice may raise or lower the credit (IRS Publication 3). Run the credit both ways before you pick. If you are married and both of you have combat pay, each spouse makes the choice on their own (IRS Publication 3).
Keep the deployment orders and the dates you entered and left the zone. They support the exclusion, and they also set the extra time you get to file.
Extra time to file after a combat zone
Serving in a combat zone pushes back your IRS deadlines. Your time to file, pay and claim a refund is extended for 180 days after you leave the zone, plus the days that were left in the filing period when you entered (IRS Publication 3). The same rule covers qualifying hospital stays and contingency operations (IRS Publication 3).
The extension does not erase interest by itself, so keep the dates exact. Your preparer needs the date you left the zone, any hospital dates and a copy of IRS notices that arrived while you were away. A spouse at home who files for you needs a power of attorney or the right signature on a joint return.
PCS moves on Form 3903
To deduct moving costs you must be on active duty, and the move must be under a military order (IRS Publication 3). A permanent change of station is the ordered move that qualifies. It includes the move to your first post of active duty, a move between posts, and the move after your last post (IRS Publication 3). You can deduct reasonable moving costs for you and your household that the government did not pay (IRS Publication 3).
The government covers much of a typical PCS move, so the deduction is often small. Moving and storage the government provided, and allowances such as dislocation and temporary lodging, stay out of income (IRS Publication 3). The deduction is what you spent above those payments, figured on Form 3903 with one form per move (About Form 3903).
That math needs three papers: the PCS orders, your own receipts, and the travel voucher or settlement that shows what DFAS paid. Without the voucher, a preparer cannot net the allowances out.
Reservists, Guard members and your state of residence
Reserve and Guard members can deduct travel for duty more than 100 miles from home, from the time they leave until they return (IRS Publication 3). You fill in Form 2106, then carry the part up to the federal rate to Schedule 1 (IRS Publication 3). Only half of meal costs count (IRS Publication 3). Keep the drill orders, mileage, lodging bills and meal receipts for each trip.
Your state return follows where you are legally at home. Your domicile is the permanent legal home you intend to return to, and it is not always where you are stationed (IRS Publication 3). A civilian spouse can elect to keep the same domicile as the service member (IRS Publication 3). Keep the record of your state of legal residence, and the spouse’s Forms W-2 from each state where they worked.
Free help exists for the whole household. MilTax, from the Defense Department, gives service members free filing software and support (Military OneSource, MilTax). The W-2 guide explains the boxes to read first.
Questions people ask
Is combat zone pay taxable?
No, for enlisted members and warrant officers it is excluded for each month served in a combat zone; officers can exclude up to a monthly cap (IRS Publication 3). The excluded amount shows in Box 12 of Form W-2 with code Q (IRS Publication 3).
Can I deduct moving expenses for a PCS move?
Yes, if you are on active duty and move under a permanent change of station order (IRS Publication 3). You deduct only the reasonable costs the government did not pay, on Form 3903 (IRS Publication 3).
Can reservists deduct travel to drills?
Yes, for unreimbursed travel more than 100 miles from home, through Form 2106 and Schedule 1 (IRS Publication 3). Shorter trips are not deductible on the federal return.
Can I deduct uniform costs?
Not on the federal return. Uniforms a service member buys are an employee cost, and the code has denied those since 2018; since the 2025 law, that denial is permanent (26 U.S.C. 67). Uniform allowances you receive are already excluded from income (IRS Publication 3).
Do I get extra time to file if I am in a combat zone?
Yes. Your deadlines are extended for 180 days after you leave the zone, plus the time left in the filing period when you entered (IRS Publication 3).
