Child support for military parents

By the HowMuchChildSupport team · Published

Child support for a service member follows the same state guidelines as any other parent. A court or child support agency in the state that hears the case adds up income, applies that state’s formula and arrives at a guideline amount. What makes military cases different is everything around that calculation: pay made up of taxable and tax-free parts, branch regulations that require support before any order exists, frequent moves across state lines, and federal protections for servicemembers who cannot appear in court because of their duties.

This guide covers those differences. It is general information, not legal advice. A military legal assistance office can help, and your state’s child support agency can explain how its rules apply to your case; the guide on how to apply for child support explains how to open a case with it.

Military pay is more than base pay

A Leave and Earnings Statement lists several kinds of pay. Base pay is taxable and always counts. So do special pays, such as flight pay, and bonuses, such as a reenlistment bonus. The harder question is the allowances: the Basic Allowance for Housing (BAH) and the Basic Allowance for Subsistence (BAS). They are not subject to federal income tax, and a parent who lives in government quarters may receive housing in kind instead of cash.

The federal Office of Child Support Enforcement’s handbook for military families puts it plainly: all state guidelines count base pay, special pay and bonuses, while their treatment of non-taxable allowances varies, and many states count BAH and BAS as income.

Among the states this site covers, the guideline income definitions of Alaska, Arizona, Arkansas, Delaware, District of Columbia, Hawaii, Kansas, Louisiana, Massachusetts, Michigan, Minnesota, Missouri, Nevada, New Jersey, Ohio, Oklahoma, South Dakota and Wisconsin expressly mention military pay, allowances or military retirement pay. Other states reach many of the same allowances through broader language about in-kind benefits that reduce living expenses. The state’s own definition, read with the Leave and Earnings Statement, decides what goes on the worksheet.

The difference matters. Take a family in Ohio with two children who live with the other parent, who earns $40,000 a year. If the service member’s base pay comes to $48,000 a year, the guideline amount is $824 a month. If housing and food allowances bring total pay to $66,000, the guideline amount becomes $1,114 a month. You can try your own figures in the child support calculator, and the income converter turns monthly or biweekly pay into the annual figure the calculator expects.

Tax-free pay raises a second question in states whose guidelines use net income. Because allowances carry no income tax, a dollar of BAH adds more to net income than a dollar of base pay. Where a state uses net income, its worksheet and instructions say how to handle non-taxable income, and some let the parent show the tax advantage. The guide to what counts as income covers the general rules.

Support before there is an order

A court order or a written agreement takes time. Until one exists, each branch requires its members to support their family members under its own regulation:

  • Army: Army Regulation 608-99
  • Air Force: Air Force Instruction 36-2906
  • Navy: MILPERSMAN article 1754-030
  • Marine Corps: Marine Corps Order P5800.16, Volume 9
  • Coast Guard: COMDTINST M1600.2

Each branch uses its own formula. The Army, Air Force and Marine Corps base interim support on a share of the member’s housing allowance, while the Navy and Coast Guard use a fraction of pay. None of them uses a state’s guideline schedule. They are a floor and a stopgap. Once a court or agency issues an order, the order controls, and the amount it sets under the state guidelines can be higher or lower than the branch figure.

A member can also start a voluntary allotment, a payment routed straight from pay to the other parent. Allotments are a good way to show support is being paid while a case is pending. The handbook warns, though, that courts treat voluntary payments differently, and some may not credit them against support later ordered for the same period unless their purpose is documented. Keep records and say in writing that the payments are child support.

The Servicemembers Civil Relief Act

The Servicemembers Civil Relief Act (SCRA) protects servicemembers on active duty, and activated Guard and Reserve members, from having civil cases decided while their duties keep them away. It applies to court and administrative child support proceedings.

A servicemember who cannot appear can ask for a stay. Under 50 U.S.C. § 3932, the court must grant a stay of at least 90 days when the request includes a letter explaining how military duty affects the ability to appear, with a date of availability, and a letter from the commanding officer confirming that duty prevents appearance and leave is not authorized. The protection continues for 90 days after release from service. Asking for a stay does not count as appearing in the case and does not waive any defense. Further delay is up to the judge or hearing officer.

The SCRA also guards against default orders. Before entering a judgment against a parent who has not appeared, the court must have a sworn statement about whether that parent is in military service, and if so it must appoint a lawyer for them first. A default entered during service, or within 60 days after release, can be reopened if service materially affected the defense and there is a real defense to raise. The application must be filed within 90 days after release.

Two limits are worth stating clearly. The stay is not automatic: the servicemember has to ask for it, in writing, with the required letters. And it delays a proceeding; it does not suspend an existing order. Support keeps accruing under a current order during deployment unless it is modified.

Enforcement and changes of station

Military pay is subject to income withholding like civilian wages. Withholding orders for Army, Navy, Air Force and Marine Corps pay, active or retired, go to the Defense Finance and Accounting Service; the Coast Guard has its own pay center. Federal limits on how much of a paycheck can be taken apply in the same way as for civilian employees; see the guide to child support enforcement.

There is also a military-specific remedy. Under 42 U.S.C. § 665, an active-duty member who falls behind under a support order by an amount equal to 2 months of support or more must make an allotment from pay and allowances. The agency or court notifies the branch’s designated official, who in turn notifies the member.

Permanent changes of station create two common issues. The first is jurisdiction: after a move, the order usually stays with the state that issued it while either parent or the child still lives there, even if the service member’s legal residence is elsewhere. The guide to child support across state lines explains how the Uniform Interstate Family Support Act decides which state can change an order, and moving out of state with a child support order covers the practical steps after a move. The second is income: a new duty station can mean a different housing allowance, and a promotion or the end of special pay can move income in either direction.

A large change in pay is a reason to look at modification, not to stop paying or to pay less on your own. Courts generally do not reduce support retroactively before a request is filed. The modification calculator compares an existing order with the current guideline amount, and the guide on how to modify child support walks through the process.

Practical steps for military families

  • Bring recent Leave and Earnings Statements to any child support case. They show every pay element, and agencies and courts work from them.
  • If no order exists, follow your branch’s interim support rule and set up an allotment, documented as child support.
  • Guard and Reserve members called to active duty should tell their civilian employer and the child support agency, so withholding moves to military pay without a gap.
  • Respond to every notice. If duty prevents you from appearing, request an SCRA stay in writing with both letters, through your legal assistance office.
  • After a move, a promotion or a change in allowances, compare the order with a new guideline estimate and ask the agency for a review if the gap is large.

Courts can deviate from the guidelines, and military cases can raise factors such as travel costs for parenting time across long distances. The guideline amount is the starting point, not the final word.

Frequently asked questions

Do housing and food allowances count as income for child support?

In many states, yes. Several state guidelines name military allowances for housing and subsistence as income even though they are not taxed. Check your state's income definition, because the treatment varies and a court applies its own state's rules.

What does a service member owe before there is a court order?

Each branch has a regulation that requires interim support for family members when there is no court order or written agreement. The amount is set by the branch's formula, not by the state guidelines, and it stops applying once a court or agency order exists.

Does deployment stop child support?

No. Deployment does not pause an existing order. The Servicemembers Civil Relief Act can delay a court or agency proceeding when duty prevents a servicemember from appearing, but payments under an existing order stay due unless the order is modified.

Can child support be taken directly from military pay?

Yes. Income withholding applies to military pay through the Defense Finance and Accounting Service, and federal law requires a mandatory allotment from an active-duty member's pay once missed payments reach a set level.
