New Jersey Statutes Title 54. Taxation 54 § 4-13

(a). If any taxpayer shall refuse or neglect to file a return as required by this chapter, the assessor shall value the taxable personal property of such taxpayer at such amount as he may, from any information in his possession or available to him, reasonably determine to be the taxable value at which such property is assessable.

(b). Any taxpayer who fails or neglects to file a return within the time prescribed by this chapter or who shall file a willfully false or fraudulent return, shall be assessed a penalty of $2.00 per day for each day of delinquency, provided that the total penalty shall not exceed $350.00 and, provided, further, that in the case of a taxpayer whose business personal property, at cost, does not exceed $25,000.00, there shall be imposed in lieu of such a penalty the appropriate penalty listed below:

$10.00 where the delinquency does not exceed 30 days;

$20.00 where the delinquency exceeds 30 days but does not exceed 60 days;

$30.00 where the delinquency exceeds 60 days but does not exceed 90 days;

$25.00 for each additional 30 days in excess of 90 days, provided that in no event shall the total penalty for such taxpayer exceed $100.00.

(c). In addition to the penalty imposed under subsection (b) of this section, any taxpayer who shall fail to file a return on or before September 1, or who shall file a willfully false or fraudulent return shall be subject to a further penalty of a sum equivalent to 25% of the amount of the tax determined to be due.

(d). The penalties imposed under subsections (b) and (c) of this section shall be added to and become part of the tax and shall be enforceable and collectible in the same manner as the tax or pursuant to the penalty enforcement law (chapter 58 of Title 2A of the New Jersey Statutes) in a summary manner. Such penalties shall be assessed by the assessor and be payable to and recoverable by the tax collector of the taxing district.

(e). The assessor, upon written request made on or before July 1, may extend the time to file the tax return to a date not later than September 1.
