New Jersey Statutes Title 54. Taxation 54 § 8A-16

(A)(1) A nonresident of this State shall be allowed a credit against the tax otherwise due under this act for any income tax imposed for the taxable year by another critical area State, of which the taxpayer is a resident but such credit shall not exceed either:

(2) No credit shall be allowed under this section unless the jurisdiction of which the taxpayer is a resident:

(1) The credit allowable under this subsection shall not exceed the percentage otherwise due under this act determined by dividing the portion of the taxpayer's income subject to taxation by such other jurisdiction by the total amount of the taxpayer's income subject to taxation under this act.

(2) The credit allowable under this subsection shall not reduce the tax otherwise due under this act to an amount less than would have been due if the income subject to taxation by such other jurisdiction were excluded from the taxpayer's income subject to tax under this act.

(3) No credit shall be allowed under this subsection for a tax of a jurisdiction which allows residents of this State a credit against the taxes imposed by such other jurisdiction for the tax under this act, if such other credit is substantially similar to the credit granted to nonresident taxpayers by subsection (A) of this section.
