New Jersey Statutes Title 54. Taxation 54 § 32B-3.5

a. Notwithstanding the provisions of the “Sales and Use Tax Act,” P.L.1966, c. 30 (C.54:32B-1 et seq.) or any other law, rule, or regulation to the contrary, a seller who makes a retail sale of tangible personal property, specified digital products, or taxable services for delivery into the State and who does not have a physical presence in the State shall be subject to the tax imposed under the “Sales and Use Tax Act,” P.L.1966, c. 30 (C.54:32B-1 et seq.), and shall collect the tax in accordance with the provisions of P.L.1966, c.30 (C.54:32B-1 et seq.) if the seller meets either of the following criteria:

b. A taxpayer complying with the provisions of P.L.1966, c. 30 (C.54:32B-1 et seq.) and this section, voluntarily or otherwise, may seek a refund or credit of a tax, penalty, or interest by following the procedures set forth in section 20 of P.L.1966, c. 30 (C.54:32B-20). However, the director shall not grant an application for a refund or credit submitted to the director pursuant to section 20 of P.L.1966, c. 30 (C.54:32B-20) on the basis that a taxpayer lacked a physical presence in the State and complied with the provisions of P.L.1966, c. 30 (C.54:32B-1 et seq.) and this section voluntarily. Nothing in this subsection shall limit the ability of a taxpayer to obtain a refund or credit on any other basis set forth in section 20 of P.L.1966, c. 30 (C.54:32B-20).

c. A seller who remits the tax imposed under the “Sales and Use Tax Act,” P.L.1966, c. 30 (C.54:32B-1 et seq.), voluntarily or otherwise, shall not be liable to a purchaser who claims that the sales tax has been over-collected because a provision of P.L.2018, c. 132 (C.54:32B-3.5 et al.) is later deemed unlawful.

d. Nothing in P.L.2018, c. 132 (C.54:32B-3.5 et al.) shall affect the obligation of any purchaser from this State to remit use tax as to any applicable transaction in which the seller does not collect and remit the sales tax or remit an offsetting sales tax.

e. The tax imposed under P.L.1966, c. 30 (C.54:32B-1 et seq.) upon sellers who meet the criteria set forth in this section and are not otherwise subject to the tax shall apply only to sales following the effective date of this section, and no obligation to collect and remit the tax imposed under P.L.1966, c. 30 (C.54:32B-1 et seq.) by sellers who meet the criteria set forth in this section may be applied retroactively.
