Military deployment: the financial checklist

A deployment is one of the few life events that can genuinely improve your finances — extra pays, tax-free income, a 10% guaranteed savings program, and months of reduced spending — but only if the paperwork and the plan are set before you leave. It's also one of the few times the law hands you special protections most people never use. Here's the sequence: what to do before you deploy, how to exploit the financial advantages while you're gone, and how to land the re-entry.

Before you go: the two-week sprint

1. Set up powers of attorney through the base legal office (free): a general or special POA so your spouse or a trusted person can handle banking, taxes, car registration, and emergencies. Special POAs limited to specific tasks are safer than a broad general POA handed to anyone but a spouse.
2. Update your will, your Servicemembers' Group Life Insurance (SGLI) beneficiaries, and your emergency data record. SGLI is $500,000 of coverage for about $30/month — confirm the beneficiary is current, not an ex.
3. Build the household operating plan: who pays which bills, from which account, with what autopay backups. Deployed communications are unreliable; the system must run without you.
4. Invoke your SCRA rights: the Servicemembers Civil Relief Act caps interest at 6% on debts you incurred BEFORE active duty — credit cards, car loans, even some mortgages — for the duration of service. You must request it in writing with your orders; lenders don't volunteer it.
5. Set a deployment budget with your family that decides in advance where the extra money goes. Unassigned windfalls evaporate; assigned ones compound.

The deployment pay stack

Deployed pay can rise substantially: Family Separation Allowance (about $250/month when separated from dependents 30+ days), Hostile Fire/Imminent Danger Pay (about $225/month in designated areas), Hardship Duty Pay, and — the big one — the Combat Zone Tax Exclusion, which makes your base pay federally tax-free while serving in a designated combat zone (officers up to a cap). A deployed E-5 can see take-home rise by $700–1,200/month between the extra pays and the vanished tax withholding, while daily spending often drops toward zero.

The two programs worth memorizing

• Savings Deposit Program (SDP): while deployed to eligible areas you can deposit up to $10,000 and earn 10% annual interest, guaranteed by the government — roughly 20x a good savings account. Set it up through finance once in country; interest continues 90 days after you return.
• Roth TSP during tax-free months: money earned under the Combat Zone Tax Exclusion and contributed to the Roth TSP is never taxed — not going in, not coming out. Deployment is the single best window of a military career to shovel money into Roth. Annual contribution limits still apply (and combat-zone service actually raises the total cap).

For the spouse or family running the home front

The at-home partner becomes the household CFO overnight. Make it manageable: one shared document listing every account, bill, due date, and login location (a password manager beats a notebook); autopay on everything fixed; a agreed threshold above which spending decisions wait for a call; and a small 'friction fund' of $1,000–2,000 for the things that always break during deployment — the car, the water heater, the dog. Military OneSource and base financial counselors are free, and the Family Separation Allowance exists precisely because running a household solo costs more.

Coming home: the re-entry plan

Reintegration has a financial failure mode: months of discipline meeting a lump of savings and a strong urge to celebrate. Plan the splurge — genuinely, on purpose, a real number like $1,500–3,000 for the trip or the toy — and protect the rest by moving it out of checking before the flight home. Then unwind the deployment machinery deliberately: SDP withdrawal after the 90-day interest tail, TSP contributions reset to a sustainable rate, SCRA rate caps end when active service ends, and the household money jobs get renegotiated rather than assumed. The couples who fight about money after deployment are usually fighting about the handoff, not the dollars.

The bottom line

Deployment finances reward preparation like almost nothing else: POAs and SGLI set before you leave, SCRA invoked in writing, the extra pay pre-assigned to SDP and Roth TSP, the home front running on autopay and a shared playbook, and a planned re-entry that includes a planned celebration. Done right, nine hard months abroad can move your family's finances forward three years. Set it up before the bags are packed.
