Quick brief: This guide highlights the military-specific rules that can save you time, money, and stress at tax time. We cover PCS (permanent change of station) moves, combat-zone extensions, what’s taxable (and what isn’t), spouse residency (MSRRA), reservist travel, and a key home-sale rule that helps during long tours.

---

1) Know what the IRS counts—and what it doesn’t

• Allowances like BAH and BAS are tax-exempt; most allowances don’t show in Box 1 of your W-2. See DoD’s overview of taxable vs. nontaxable pays and allowances: DoD Military Pay — Allowances.
• Combat-zone pay for enlisted and warrant officers is generally excluded from income (officer exclusion is capped). If you served in a combat zone, special deadline extensions apply (more below). Start with IRS: Combat Zones.
• VA benefits such as disability compensation (and many education benefits) are not taxable. See IRS: Information for Veterans and IRS Publication 907.

2) PCS move in 2025–2026? You may still deduct moving expenses

The Tax Cuts and Jobs Act suspended moving-expense deductions for most people—but active-duty members on orders for a PCS are the exception. You can deduct reasonable unreimbursed moving expenses (and exclude eligible reimbursements). Use Form 3903 with your return and see IRS Topic 455 (Moving Expenses—Armed Forces). Keep orders and receipts.

Pro tips for your PCS file:

• Save certified weight tickets, HHG invoices, storage and transportation receipts, and lodging receipts (meals typically aren’t deductible).
• If you received a partial reimbursement, the shortfall can be deductible; excess reimbursements are taxable. Your tax software or preparer will reconcile this on Form 3903.

3) In a combat zone or stationed OCONUS? Understand your clock

• Combat zone deadline relief: You generally get at least 180 days after leaving the combat zone to file and pay federal taxes. Spouses usually qualify too. Interest and penalties tied to the postponed period are suspended. Start here: IRS: Combat Zones.
• Living outside the U.S. on April 15: You receive an automatic 2-month filing extension (to mid-June). You can also request the standard extension to October by filing Form 4868. (Payment is still due by the original deadline unless you’re in a combat zone.) See IRS guidance for taxpayers abroad.

4) Reservists/Guard: the 100-mile travel deduction

If you’re a member of the Reserve components and travel more than 100 miles from home and stay overnight for drills/meetings, you may claim above-the-line deductions for transportation, lodging, and meals (subject to federal per-diem limits). Use Form 2106 and carry the allowed amount to Schedule 1. See IRS Topic 511. Keep mileage logs and receipts.

5) Military spouses: Residency & state taxes (MSRRA)

Under the Military Spouses Residency Relief Act (MSRRA), a spouse who moves with the service member may keep (or elect) the same state of legal residence for tax purposes, rather than adopting the duty-station state. This can reduce mid-tour state tax surprises. See the residency and filing guidance in IRS Publication 3 — Armed Forces’ Tax Guide, then check your state’s revenue site to update HR/payroll withholding.

6) Maximize family credits: the EITC and a special combat-pay rule

If you qualify for the Earned Income Tax Credit (EITC), you can elect to include nontaxable combat pay as earned income only for EITC purposes—sometimes increasing your credit. Carefully test both ways in software before filing. See IRS: Earned Income Tax Credit.

7) Selling a home during/after a long tour? Know the PCS “time-test” break

Normally, to exclude up to $250,000 ($500,000 MFJ) of gain, you must have owned and used the home as your main home for 2 of the last 5 years. Service members on qualified extended duty can suspend the 5-year window for up to 10 years, which can preserve your exclusion after multi-year assignments. See IRS Topic 701 and Publication 523. Coordinate timing with your agent and tax pro.

8) Paperwork checklist (save these in your “tax go-bag”)

• Orders (PCS, deployment, TDY), LES copies, and myPay W-2s/1095-C.
• Form 1099-R if you received retirement/disability pay; VA letters if benefit changes affected prior returns. See Form 1099-R.
• PCS receipts: lodging, transportation, storage, certified weight tickets.
• Reservist logs: mileage, per-diem dates/locations, lodging receipts.
• Closing disclosures if you bought/sold—and any landlord records if you converted a prior home to a rental mid-tour.

9) Free, military-savvy filing help

• MilTax (Military OneSource): DoD’s free e-filing software plus access to tax consultants trained on military situations. For 2026, MilTax software availability begins Jan. 15, 2026. Start here: MilTax at Military OneSource.
• VITA on base/nearby: Many installations host IRS-certified Volunteer Income Tax Assistance sites; you can also search community VITA programs via the IRS VITA locator.

10) Timing your housing moves around taxes

If you’re inbound with a report date soon, factor tax timing into your housing plan:

• Short tours often favor renting, especially if you’ll sell within two years and won’t meet the standard home-sale test (unless you’ll rely on the extended-duty suspension above).
• BAH/BAS are tax-free, but mortgage interest and property taxes can still be deductible if you itemize—your preparer/software will evaluate that trade-off.

If you’re outbound, decide early whether to sell or rent your home during the next tour. Renting may trigger different record-keeping, depreciation, and state-tax considerations—talk to a tax professional before you list or lease.

11) Fieldcraft for an easier tax season

• Label everything: keep a digital folder titled 2025-Taxes with subfolders for PCS, EITC, Reservist Travel, and Home Sale.
• Check your state: MSRRA helps, but states vary on filing mechanics. Confirm with your state revenue department (see IRS Pub 3) and adjust withholdings ASAP.
• Run both scenarios for EITC if you had combat pay (include vs. exclude). See EITC guidance.
• Don’t forget extensions if you were in a combat zone or stationed OCONUS—use them intentionally to gather complete documentation. See combat-zone relief and Form 4868.

FAQs

Are BAH and BAS taxable?
No. BAH and BAS are tax-exempt and won’t appear in Box 1 of your W-2. See DoD Allowances.

Can I deduct PCS moving expenses?
Yes—if you’re active duty moving on official orders. Use Form 3903 for unreimbursed, reasonable costs (transport, storage, lodging—not meals). See Topic 455. Keep orders and receipts.

Can we still exclude the gain on a home sale after a long tour?
Often. Service members on qualified extended duty can suspend the 2-in-5-year test for up to 10 years. See Topic 701 and Publication 523.

Which PCS documents should I save for taxes?
Orders, LES, W-2s, certified weight tickets, transportation/storage invoices, lodging receipts, and closing disclosures if you bought/sold. See Topic 455 for what counts.

How should taxes factor into our rent-vs-buy decision at the new duty station?
Tour length, BAH, itemizing vs. standard deduction, and potential home-sale timing all matter. Coordinate early with your lender, tax pro, and agent; review Publication 523 for sale timing basics.

We converted our prior home to a rental during PCS. Tax implications?
Rentals involve depreciation, prorated expenses, and possible multi-state filings. Keep detailed records and consult a qualified tax professional (education only).

How do state taxes work if we move mid-year?
It depends on residency. MSRRA may allow the spouse to retain a single state of residence; see IRS Publication 3 and your state’s revenue site. Adjust withholding early.

Key terms

• PCS (Permanent Change of Station): an official move to a new duty station.
• BAH/BAS: housing and subsistence allowances, generally non-taxable.
• MSRRA: Military Spouses Residency Relief Act—lets eligible spouses keep or elect the service member’s state of residence.
• EITC: Earned Income Tax Credit—refundable credit for qualifying taxpayers; special combat-pay rule may increase eligibility/amount.

Bottom Line

Military taxes have unique advantages—tax-free BAH/BAS, PCS moving-expense deductions, combat-zone filing extensions, MSRRA residency protections for spouses, the 100-mile reservist travel deduction, and a special home-sale exclusion for extended duty. Keep orders and receipts, test EITC with/without combat pay, and use MilTax/VITA for free, military-savvy help.
