> **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](https://www.irs.gov/publications/p3)). 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](https://www.irs.gov/publications/p3)).

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](https://www.irs.gov/publications/p3)). Almost every other job cost, such as uniforms you buy yourself, is barred on the federal return ([26 U.S.C. 67](https://www.law.cornell.edu/uscode/text/26/67)).

| Item | Tax treatment | Document that proves it |
| --- | --- | --- |
| Combat zone pay | Excluded from income ([IRS Publication 3](https://www.irs.gov/publications/p3)) | Form W-2, Box 12 code Q, and deployment orders |
| BAH, BAS, uniform allowance | Excluded from income ([IRS Publication 3](https://www.irs.gov/publications/p3)) | Leave and Earnings Statement |
| PCS move costs not reimbursed | Deduction on Form 3903 ([IRS Publication 3](https://www.irs.gov/publications/p3)) | PCS orders, receipts, travel voucher |
| Reservist travel over 100 miles ([IRS Publication 3](https://www.irs.gov/publications/p3)) | Deduction via Form 2106 ([IRS Publication 3](https://www.irs.gov/publications/p3)) | Drill orders, lodging and travel receipts |
| Uniforms bought yourself | Not deductible federally ([26 U.S.C. 67](https://www.law.cornell.edu/uscode/text/26/67)) | 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](https://www.irs.gov/publications/p3)). Commissioned officers have a cap: the highest rate of enlisted pay plus imminent danger pay for each month ([IRS Publication 3](https://www.irs.gov/publications/p3)). For 2025, the IRS puts that cap at $10,983 a month ([IRS Publication 3](https://www.irs.gov/publications/p3)).

The excluded amount still shows on your W-2, in Box 12 with code Q ([IRS Publication 3](https://www.irs.gov/publications/p3)). 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](https://www.irs.gov/publications/p3)). 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](https://www.irs.gov/publications/p3)).

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](https://www.irs.gov/publications/p3)). The same rule covers qualifying hospital stays and contingency operations ([IRS Publication 3](https://www.irs.gov/publications/p3)).

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](https://www.irs.gov/publications/p3)). 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](https://www.irs.gov/publications/p3)). You can deduct reasonable moving costs for you and your household that the government did not pay ([IRS Publication 3](https://www.irs.gov/publications/p3)).

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](https://www.irs.gov/publications/p3)). The deduction is what you spent above those payments, figured on Form 3903 with one form per move ([About Form 3903](https://www.irs.gov/forms-pubs/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](https://www.irs.gov/publications/p3)). You fill in Form 2106, then carry the part up to the federal rate to Schedule 1 ([IRS Publication 3](https://www.irs.gov/publications/p3)). Only half of meal costs count ([IRS Publication 3](https://www.irs.gov/publications/p3)). 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](https://www.irs.gov/publications/p3)). A civilian spouse can elect to keep the same domicile as the service member ([IRS Publication 3](https://www.irs.gov/publications/p3)). 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](https://www.militaryonesource.mil/financial-legal/taxes/miltax-military-tax-services/)). The [W-2 guide](/documents/w-2) 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](https://www.irs.gov/publications/p3)). The excluded amount shows in Box 12 of Form W-2 with code Q ([IRS Publication 3](https://www.irs.gov/publications/p3)).

### 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](https://www.irs.gov/publications/p3)). You deduct only the reasonable costs the government did not pay, on Form 3903 ([IRS Publication 3](https://www.irs.gov/publications/p3)).

### 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](https://www.irs.gov/publications/p3)). 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](https://www.law.cornell.edu/uscode/text/26/67)). Uniform allowances you receive are already excluded from income ([IRS Publication 3](https://www.irs.gov/publications/p3)).

### 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](https://www.irs.gov/publications/p3)).
