The Society for Science Real Property Tax Exemption Amendment Act of 2025 aims to provide a real property tax exemption for specific properties located at 1719 N St., N.W., 1723 N St., N.W., and 800 8th St. NW, which are owned by or being sold to the Society for Science, Inc. The bill amends Chapter 10 of Title 47 of the District of Columbia Official Code by adding a new section, 47-1099.13, that outlines the tax exemption for these properties, stating that the exemption applies as long as the properties 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 that may be available to the Society for Science, Inc. This legislation will take effect after being approved by the Mayor, undergoing a 30-day congressional review, and being published in the District of Columbia Register.
