As you may know, the Monthly Housing Allowance (MHA) payments you receive for the Post-9/11 GI Bill are based on the military’s Basic Allowance for Housing (BAH) rates for an E-5 with dependents. Department of Defense adjusts the military BAH rate every calendar year (or January 1) based on changes to housing costs across the country. Rates can either go up or down.Public Law 111 – 377 (the Veterans Educational Assistance Improvement Act of 2010) amended the effective date for the adjustment of the MHA you receive under the Post-9/11 GI Bill from the beginning of the calendar year (January 1) to the beginning of the academic year (August 1). Therefore , if the BAH increased for your area, you will not see an increase until your September 2012 payment for training pursued in August. If the BAH decreases for your area, your MHA amount will not decrease unless you change schools or have more than a six-month break in training.
