Establishes "Subaccount for School Funding Protection" reserve account in Property Tax Relief Fund to prevent state aid losses for schools during economic emergency.

This bill creates a dedicated "Subaccount for School Funding Protection" within New Jersey's Property Tax Relief Fund. It requires the State Treasurer to deposit annually, by December 31, at least 50% of any excess revenue collected in the Property Tax Relief Fund above the Governor's certified estimate. The subaccount can only be accessed to protect school funding during economic emergencies or if Property Tax Relief Fund revenues fall short of projections, preventing cuts to school aid. It cannot be used for general state spending unless specific conditions are met, such as a projected revenue decline exceeding 2% or a declared emergency affecting schools. This directly safeguards public school funding during economic downturns.
