N.J. Stat. § 54:4-75
For the purpose of this section:
"School tax due" or "tax due" means the amount so assessed less the school district's proportionate share of the property taxes no longer owed by the municipality pursuant to the blue acres property tax exemption established by subsection b. of section 1 of P.L. 2013, c. 261(C.54:4-3.3g) and less any applicable credit established by subsection e. of section 1 of P.L. 2013, c. 261(C.54:4-3.3g).
The governing body of each municipality shall pay over to the board secretary or treasurer of school moneys, as appropriate, in the case of school districts in which appropriations for school purposes are made by the inhabitants of the school district, within forty days after the beginning of the school year, twenty per centum (20%) of the moneys from school tax due, and thereafter, but prior to the last day of the school year, the balance of the moneys from school tax due for school purposes in such amounts as may be requested from time to time by the Board of Education, within thirty days after each request. The Board of Education shall not request any more money at any one time than shall be required for its expenditures for a period of eight weeks in advance; provided, however, that the Board of Education may at any time, but not earlier than fifteen days prior to the beginning of the school year, request sufficient moneys to meet all interest and debt redemption charges maturing during the first forty days of the school year. The governing body may make payments of such moneys in advance of the time and in excess of the amounts required by this section. Notwithstanding provisions of this section to the contrary, in those years when the third installment of property taxes has been determined by the tax collector to be due after August 10, the installment shall be due no later than five days after the twenty-fifth day from when the tax bill was mailed or otherwise delivered pursuant to subsection a. of R.S. 54:4-64, but no later than September 1.
