Art Gallery Tax Exemption Amendment Act of 2025

The Art Gallery Tax Exemption Amendment Act of 2025 would allow non-profit art galleries and museums in Washington, D.C., to claim full property tax exemptions for their entire buildings, including office space and operational areas used to support their cultural mission. Currently, some small galleries (like Hillery Gallery and Heurich House) only received partial exemptions because existing law excluded space used for business operations, even when those activities supported their cultural work. The bill amends DC tax code §47-1002(6) to extend exemptions to all mission-related building space, as long as operations aren't "unrelated trade or business activities." This change directly benefits non-profit cultural institutions seeking consistent tax relief for their full facilities.
