Relating to the authority of certain municipalities to use certain tax revenue for certain qualified projects.

HB 3620 amends Texas tax code to allow specific cities to use certain local tax revenues for qualified projects. It applies only to municipalities meeting strict population criteria, such as cities with 700,000-950,000 residents, cities covering over 70% of a county with 1.5 million+ people, or cities in two counties each exceeding 900,000 residents. The bill expands existing authority by clarifying which tax revenues can fund eligible projects, though it does not define "qualified projects" or specify new funding mechanisms. The law takes effect September 1, 2025.
