New Jersey Statutes Title 40A. Municipalities and Counties 40A § 27-19

The chief fiscal officer of each contracting local unit which enters into a contract pursuant to this chapter, shall cause to be paid to the contractor, at the times agreed upon, the amount of money certified to the contracting local unit by the contractor pursuant to this chapter. The power and obligation of the contracting local unit to provide for and make all payments is unlimited and the sums necessary for the payment shall be included in each annual budget of the contracting local unit; and the contracting local unit shall be irrevocably and unconditionally obligated to levy ad valorem taxes on all taxable property therein, without limits as to rate or amount, to the full extent necessary to make all payments, in full, as they become due. If any part of the amount certified to a contracting local unit by a contractor, pursuant to this act, remains unpaid for 30 days following the date fixed for payment by the contract, the contracting local unit thus in default shall be charged with and be liable for, and the chief fiscal officer thereof shall pay to the contractor, interest upon the amount unpaid at the rate of 8% per year.
