Taxes for Service Members — Combat Pay, State Residency, and PCS Deductions
Military taxes come with rules written specifically for you — a combat-zone exclusion, state residency protections, spouse relief, and one of the last moving deductions in the tax code. Most of them are opt-in by knowledge: use them or lose them.
The biggest recurring one is state taxes. Your state of legal residence follows you regardless of station, and several states tax military pay lightly or not at all. Service members who never examine their SLR can pay state tax for years that they never owed.
Your reality
The parts of this topic that hit your trade differently — and that generic advice skips.
Combat-zone months are federal-tax-free
Base pay earned in a designated combat zone is excluded from federal income tax, and even one day in the zone excludes the month. Those months also open doors — Roth contributions from untaxed pay, and elections around the EITC that can raise a refund.
Your state of legal residence is a choice with rules
SLR isn't where you're stationed; it's the state where you've established legal ties — and it follows you worldwide. Changing it requires genuine steps (residence, vehicle, voting), not a mailbox. Done legitimately, it can end a state tax bill permanently.
Military spouses get residency relief too
Under MSRRA and its updates, a spouse can generally keep or share the service member's state of legal residence for tax purposes instead of being re-taxed by every duty-station state. Employers get this wrong constantly — the withholding is worth checking every move.
First moves
Three concrete steps, in order. Each one is a brick laid.
Audit your SLR and your spouse's election
Confirm what state you're a legal resident of, what it taxes, and whether your spouse's employer is withholding for the right state. Legal assistance and base tax centers handle these questions free.
Keep every PCS receipt
Active-duty members moving on orders can still deduct unreimbursed moving expenses — one of the few moving deductions left in the code. The receipts are the deduction.
Re-run withholding after a deployment year
A year with combat-zone months looks nothing like a normal tax year. Check withholding and consider whether the EITC election on combat pay helps — a free session at the base tax center settles it.
Frequently asked questions
Do I pay state income tax where I'm stationed?
Generally not on your military pay — the Servicemembers Civil Relief Act lets you keep your state of legal residence regardless of station. Civilian side income earned in the duty-station state can still be taxed there. Your SLR's rules govern the military paycheck.
How does MSRRA help my spouse?
It generally lets your spouse claim the same state of legal residence you hold, instead of paying taxes to each new duty-station state. That can mean a state tax bill of zero if your shared SLR doesn't tax wages — but the spouse's employer must withhold accordingly, which usually takes a form and a conversation.
Are BAH and BAS taxable?
No — housing and subsistence allowances are tax-free, which is part of why military take-home stretches further than the base-pay number suggests. It's also why budgeting for civilian life needs care: replacing tax-free allowances takes more gross salary than it looks.
