This bill amends the Internal Revenue Code of 1986 to expand eligibility for qualified opportunity zone designation. It specifically allows population census tracts that contain any portion of a former Department of Defense installation, facility, or entity closed under a base realignment and closure (BRAC) round to be designated. A key provision is that these former military installation tracts are exempt from the typical low-income community requirements that other opportunity zones must meet. Additionally, the number of such tracts designated in a state will increase the total number of qualified opportunity zones permitted for that state, effectively allowing more designations beyond the current limits. This aims to incentivize investment and redevelopment in areas impacted by military base closures by providing tax benefits.
