Over and above basic pay, members of military have a salary that is divided into many categories.  Generally, all categories that provide income (basic pay), or that defray a personal cost are considered income for child support purposes.  For example BAH (basic allowance for housing) and BAQ (basic allowance for quarters), categories that represent housing allotments paid to a serviceman, are considered income for child support purposes.  These amounts are paid to a serviceman to be used to reimburse payment of, of to pay, for his residence.  Keep in mind that whether a payment is “taxable” income for state or federal purposes does not guide whether it is considered income for child support purposes.
