The New Jersey Constitution of 1947 (Annotated) Art. VIII, § I, ¶ 7

7. a. No tax shall be levied on personal incomes of individuals, estates and trusts of this State unless the entire net receipts therefrom shall be received into the treasury, placed in a perpetual fund designated the Property Tax Relief Fund and be annually appropriated, pursuant to formulas established from time to time by the Legislature, to the several counties, municipalities and school districts of this State exclusively for the purpose of reducing or offsetting property taxes.  In no event, however, shall a tax so levied on personal incomes be levied on payments received under the federal Social Security Act, the federal Railroad Retirement Act, or any federal law which substantially reenacts the provisions of either of those laws.

b. There shall be annually credited from the General Fund and placed in a special account in the perpetual Property Tax Relief Fund established pursuant to this paragraph, which account shall be designated the Property Tax Reform Account, an amount equal to the annual revenue derived from a tax rate of 0.5% imposed under the “Sales and Use Tax Act,” P.L.1966, c.30 (C.54:32B-1 et seq.), as amended and supplemented, or any other subsequent law of similar effect, which amount shall be appropriated annually by the Legislature exclusively for the purpose of property tax reform.
