What is BAH-Diff?
BAH-DIFF is the housing allowance amount for a member who is assigned to single-type quarters and who is authorized a BAH solely by reason of the member’s payment of child support. A member is not authorized BAH-DIFF if the monthly rate of that child support is less than the BAH-DIFF amount. The BAH-DIFF amounts, originally calculated in 1997, are updated annually based on changes in the Basic Pay tables. For more information contact your servicing finance office or consult JFTR, par. U10008.
