Establishes limits upon local government tax levies

This bill sets limits on property tax increases for New York counties, cities, towns, and villages (excluding New York City and certain counties). It specifically caps how much local governments can raise taxes to cover teacher retirement costs when the required contribution rate jumps more than 2 percentage points from the previous year. The law clarifies that these limits apply to most property tax levies but exclude certain special assessments authorized under specific state provisions. The goal is to prevent sudden, large tax hikes on residents by tying increases to predictable factors like retirement system costs.
