Clarifies notice required to be provided to property taxpayers of change in interest rate on delinquent property taxes under certain emergency circumstances; permits municipality to extend grace period under certain emergency circumstances.

This bill (A1117) modifies New Jersey's property tax rules to provide relief during specific emergencies. It allows municipalities to waive interest on overdue property taxes for affected taxpayers during declared natural disasters (like floods or hurricanes), public health emergencies, or federal government shutdowns. Key mechanisms include requiring municipal resolutions to waive interest (with specific deadlines for notifying state officials), defining proof needed for federal shutdown cases (e.g., pay stubs showing federal employment disruption), and setting grace periods up to 30 days for health emergencies. It directly affects property owners in municipalities that declare these emergencies, ensuring they aren't charged interest if they pay by specified deadlines. The bill does not change tax rates but adjusts enforcement during crisis periods.
