The Society for Science Real Property Tax Exemption Amendment Act of 2025 aims to provide a real property tax exemption for specific properties owned by or being sold to the Society for Science, Inc. The properties in question are located at 1719 N St., N.W., 1723 N St., N.W., and 800 8th St. N.W. The bill amends Chapter 10 of Title 47 of the District of Columbia Official Code by adding a new section, 47-1099.13, which outlines the tax exemption for these properties as long as they are owned and used by the Society for Science, Inc.

Additionally, the bill clarifies that the tax exemption is supplementary to any other tax relief or assistance the Society for Science, Inc. may receive from other sources. The legislation will take effect following the Mayor's approval, a 30-day congressional review period, and publication in the District of Columbia Register.
