No Tax Subsidies for Stadiums Act of 2025

This bill prohibits state and local governments from using tax-exempt bonds to fund new professional sports stadiums. It defines a "professional stadium bond" as any bond financing a facility hosting professional sports events for at least 5 days yearly, blocking tax-exempt status for such bonds issued after enactment. The law directly affects municipalities, sports teams, and developers seeking tax-free financing for stadium construction or major renovations. It changes the tax code to eliminate a common subsidy method for new sports venues, applying only to future projects.
