The Tax and Revenue Commission Establishment Amendment Act of 2025 aims to create a permanent Tax and Revenue Revision Commission as an independent agency within the District of Columbia. The Commission's primary purpose is to provide expert recommendations to the Mayor and Council regarding revisions to the District's tax code and other significant non-tax revenue sources. The bill outlines the Commission's duties, which include promoting fairness and equity in tax apportionment, broadening the tax base, assessing the impact of fines and fees, encouraging business growth, and modernizing the tax code. Additionally, the Commission is tasked with conducting comprehensive analyses of the current tax system and proposing innovative solutions to meet the District's revenue needs.

The bill also establishes an Advisory Group to assist the Commission, consisting of both voting and non-voting members, including experts in taxation and representatives from the community and business sectors. The Commission is required to submit comprehensive updates to the tax code every ten years, with the first update due by February 12, 2025. Furthermore, the Commission must provide yearly reports with recommendations for improvements and technical updates to the tax code outside of the decennial updates. The legislation repeals certain existing provisions and introduces new sections to facilitate the establishment and operation of the Commission and its Advisory Group.
