California Family Code 4058
Child Support Calculations With Military Income
How BAH, BAS, and special pays factor into California support orders
California Family Code 4058 requires courts to consider all income from whatever source derived when calculating child support. For military parents, this statutory language captures far more than basic pay. The complex web of allowances, special pays, and nontaxable compensation creates calculations that civilian attorneys often mishandle. Missing an allowance or special pay can produce a support order that undercompensates the child or overburdens the service member.
Many attorneys mistakenly exclude BAH and BAS from support calculations because these allowances are nontaxable. California courts include them because they represent real economic benefits that reduce living expenses.

At Hayat Family Law, we help clients ensure that military income is calculated accurately. Working with military divorce lawyers who understand pay structures prevents the errors that plague civilian attorneys who rarely handle military cases. The consequences of miscalculation affect children for years, creating either insufficient support for their needs or excessive burdens on the service member that jeopardize their financial stability.
All military compensation counts as income under FC 4058. This includes basic pay, Basic Allowance for Housing, Basic Allowance for Subsistence, cost of living adjustments, special pays for hazardous duty, flight pay, sea pay, and enlistment bonuses. Even nontaxable allowances like BAH and BAS are included because they represent compensation that reduces living expenses. The only significant exclusions are certain combat zone exclusions and some disability related payments, though courts vary on combat pay treatment.
The inclusion of nontaxable income creates a counterintuitive result for many service members. A member who receives $3,000 in basic pay and $2,000 in BAH may believe their income for support purposes is $3,000. California courts treat it as $5,000. This misunderstanding causes service members to agree to support amounts they cannot afford or to challenge orders that actually reflect their true economic capacity. Proper legal representation ensures that the calculation starts from the correct baseline.
Fact 1: All Military Compensation Counts as Income
California Family Code 4058 includes basic pay, BAH, BAS, COLA, special pays for hazardous duty, flight pay, sea pay, and enlistment bonuses. Even nontaxable allowances are included because they represent real economic benefits. The broad definition of income captures nearly every form of military compensation. Courts have consistently held that the statutory language leaves no room for excluding allowances merely because they are not taxed.
The California Supreme Court has interpreted FC 4058 broadly in multiple decisions. The statute defines income as including commissions, royalties, bonuses, and all other income from whatever source derived. Military allowances fit squarely within this definition. BAH covers housing expenses that civilian employees must pay from their own pockets. BAS covers food expenses that civilian workers pay after tax. Including these allowances in support calculations simply levels the playing field between military and civilian parents.
Fact 2: BAH and BAS Are Included Even Though Nontaxable
Many service members and spouses believe that because BAH and BAS are not taxed, they are not counted for support. This is incorrect. California courts treat these allowances as income because they represent real economic benefits. A service member receiving $2,000 in BAH and $400 in BAS will have those amounts added to their basic pay for support calculation purposes. The nontaxable nature of these allowances does not exempt them from support obligations.
The nontaxable status of BAH and BAS actually makes them more valuable than taxable income of the same amount. A civilian employee who receives $2,000 in taxable salary keeps perhaps $1,500 after taxes. A service member who receives $2,000 in BAH keeps the full $2,000. California courts recognize this economic reality and include the full allowance amount in support calculations. The service members nontaxable compensation provides greater disposable income than a civilian’s taxable wages.
Fact 3: Combat Zone Pay May Be Excluded Temporarily
Income earned while serving in a combat zone is excluded from federal taxation under the Internal Revenue Code. California courts may exclude this income from support calculations during the deployment period, though courts differ on this issue. Some judges include combat pay because it represents actual income, while others exclude it consistent with federal tax treatment. The treatment varies by county and by individual judge.
The combat pay exclusion creates particular challenges for support modification during deployment. When a service member deploys to a combat zone, their income may increase significantly due to combat pay, family separation allowance, and tax advantages. If the court excludes combat pay from the support calculation, the childs support may not increase despite the members higher income. If the court includes combat pay, the support may increase substantially for the deployment period and then decrease when the member returns home.
Fact 4: Support Orders Can Be Modified When Income Changes
Military income fluctuates with promotions, changes in BAH rates, special duty assignments, and separations. California Family Code 4058 allows either parent to request modification when income changes significantly. A service member who receives a promotion or begins collecting a new allowance may face a support increase. Conversely, a service member who separates from the military and loses BAH may qualify for a support reduction.
Modification requires a material change in circumstances. A 10% increase in income may not justify modification, while a 50% increase probably does. The court examines the totality of the circumstances, including whether the change was voluntary, whether it was foreseeable, and whether it affects the childs needs. A service member who voluntarily leaves the military to pursue a lower paying civilian career may face resistance to a support reduction, while a member who is medically discharged may receive more favorable treatment.
The modification process requires filing a request with the court, serving the other parent, and presenting evidence of the income change. Both parties should provide current Leave and Earnings Statements, tax returns, and documentation of any new allowances or special pays. The court then recalculates support using the California Guideline Calculator and issues a modified order. This process typically takes 3 to 6 months, during which the original order remains in effect.
