Requires Governor to transmit budget sustainability statement along with annual budget message.

S 2510 requires New Jersey's Governor to include a budget sustainability statement with the annual budget message. This statement must analyze whether proposed spending for the next fiscal year can be sustained without raising taxes or reducing state savings, including accounting for structural spending gaps, one-time revenues, and mandatory increases from debt payments, contracts, or public assistance programs like Medicaid. The bill mandates that any projected spending increases must be offset by estimated future revenue or reduced mandatory spending. It applies to all budget recommendations and takes effect immediately for the next budget cycle. This requirement aims to improve long-term fiscal planning by making sustainability analysis a standard part of the budget process.
