New Jersey Statutes Title 54. Taxation 54 § 8A-49

(a) Every employer required to deduct and withhold tax under this act shall, for each calendar quarter, on or before the last day of the month following the close of such calendar quarter, file a withholding return as prescribed by the Division of Taxation and pay over to the Division of Taxation the taxes so required to be deducted and withheld; but the Division of Taxation may, by regulation, provide that every such employer shall on or before the fifteenth day of each month pay over to the Division of Taxation, or a depositary designated by the Division of Taxation, the taxes so required to be deducted and withheld if such taxes aggregate $100.00 or more for the preceding calendar month. Where the aggregate amount so deducted and withheld by any employer is less than $25.00 in a calendar quarter and the aggregate for the calendar year can reasonably be expected to be less than $100.00, the Division of Taxation may by regulation permit an employer to file an annual return. The Division of Taxation may, if it believes such action necessary for the protection of the revenues, require any employer to make such return and pay to it the tax deducted and withheld at any time, or from time to time.

(b) Whenever any employer fails to collect, truthfully account for, pay over the tax, or make returns of the tax as required in this section, the Division of Taxation may serve a notice requiring such employer to collect the taxes which become collectible after service of such notice, to deposit such taxes in a bank approved by the Division of Taxation in a separate account, in trust for and payable to the Division of Taxation and to keep the amount of such tax in such account until payment over to the Division of Taxation. Such notice shall remain in effect until a notice of cancellation is served by the Division of Taxation.
