BAS is meant to offset costs for a member's meals. This allowance is based in the historic origins of the military in which the military provided room and board (or rations) as part of a member's pay. This allowance is not intended to offset the costs of meals for family members. Beginning on January 1, 2002, all enlisted members get full BAS, but pay for their meals (including those provided by the government). This is the culmination of the BAS Reform transition period.

Because BAS is intended to provide meals for the service member, its level is linked to the price of food. Therefore, each year it is adjusted based upon the increase of the price of food as measured by the USDA food cost index. This is why the increase to BAS will not necessarily be the same percentage as that applied to the increase in the pay table, as annual pay raises are linked to the increase of private sector wages.

There are several types of BAH to satisfy various housing situations that occur among military members. In general, the amount of BAH you receive depends on your location, pay grade, and whether you have dependents. Under most circumstances, you receive BAH for the location where you are assigned, not where you live. Additionally, you may be entitled to some BAH amounts if you are residing separately from your dependents. This occurs in situations involving unaccompanied overseas tours or having a dependent child that resides with a former spouse. The rules regarding these situations can become quite complex. Consult your Finance Office if you are in one of these situations. Each type of BAH is described below.

BAH With Dependents and BAH Without Dependents

A member with permanent duty within the 50 United States, who is not furnished government housing, is eligible for Basic Allowance for Housing (BAH), based on the member's dependency status at the permanent duty ZIP Code. A member stationed overseas, including U.S. protectorates, who is not furnished government housing, is eligible for Overseas Housing Allowance (OHA) based on the member's dependency status. If a member is serving an UNACCOMPANIED overseas tour, the member is eligible for BAH at the "with dependents" rate, based on the dependent's US residence ZIP Code, plus OHA at the "without dependents" rate, if the member is not furnished government housing overseas.

Partial BAH

A member without dependents who is living in government quarters is entitled to a Partial BAH.

BAH Reserve Component/Transit (BAH RC/T)

BAH RC/T is a non-locality housing allowance for members in particular circumstances, for example, reservists on active duty for 30 or fewer days. It also applies when a member is in transit from selected areas where no prior BAH rate exists (such as overseas). It does not vary by geographic location. BAH RC/T was set based on the old Basic Allowance for Quarters (BAQ), which was based on the national average for housing. BAH RC/T is published annually and is determined by increasing the previous year's rates by the national average percentage growth of housing costs.

BAH-Differential (BAH-Diff)

BAH-Diff is the housing allowance amount for a member who is assigned to single-type quarters and who is authorized a basic allowance for housing solely by reason of the member's payment of child support. A member is not entitled to BAH-Diff if the monthly rate of that child support is less than the BAH-Diff. BAH-Diff is determined by the SECDEF and was equal to the difference between BAQ with dependents and BAQ without dependents in 1997 for the member's grade. BAH-Diff is published annually and is determined by increasing the previous year's rates by the percentage growth of military basic pay. For more information contact your finance office.
