Managing money while your spouse is deployed

A deployment reshapes a household's finances overnight: income often rises (tax-free pay, special pays, the SDP), expenses can shift, and one partner may suddenly manage everything alone. Whether the family comes home to a transformed balance sheet or a tangle of missed bills and a surprise truck loan depends almost entirely on the setup done before departure. For the at-home partner, a deployment is a project to run deliberately, not a fog to survive.

Set it up before they leave

The most important financial work happens in the weeks before deployment, at the legal office and the kitchen table. Powers of attorney let the at-home partner handle accounts, housing, and vehicles. Updated SGLI beneficiaries and a will protect the family. And both partners need visibility into every account, password, and bill - a deployment is exactly when a scattered, one-person-knows-it-all setup becomes a crisis for the person left behind.

1. Get a general or special power of attorney appropriate to what you'll need to handle.
2. Update SGLI beneficiaries and complete or refresh wills at the free legal office.
3. Write down every account, login, automatic payment, and due date in one place both partners can reach.
4. Automate every bill so nothing depends on someone remembering during a hard month.
5. Agree in advance where the deployment's extra money goes - before it lands.

Capture the deployment upside

The at-home partner can actively drive the household's wealth during a deployment. Make sure the SDP allotment starts as soon as the member is eligible (guaranteed 10% on up to $10,000). Raise the Roth TSP percentage to pour tax-free pay into tax-free growth. Route the special pays - Family Separation Allowance, Hostile Fire Pay - straight to savings rather than lifestyle. With the deployed member's personal spending near zero downrange, the household savings rate can spike for the duration if someone at home is steering the surplus.

Guard against the at-home traps

Deployment can also quietly leak money if no one's watching: childcare and household help the deployed partner used to provide now cost money, solo parenting invites convenience spending, and morale purchases add up. None of these are failures - they're real costs that deserve a line in the budget rather than a surprise on the statement. Budget for the added at-home expenses honestly, use the family readiness resources and relief societies if a genuine emergency hits, and keep the automated bills running so the household never slips while attention is elsewhere.

The bottom line

A deployment is one of the best wealth-building windows in military life - but only for households that set it up first. Before departure, get the powers of attorney, wills, beneficiaries, and account visibility in order and automate every bill. During the deployment, start the SDP, raise the Roth TSP, and route special pays to savings. And pre-decide where the homecoming money goes so it funds the family's future instead of a week-one truck. Run deliberately, a hard separation becomes a financial leap the whole family shares.
