N.J. Stat. § 54:4-63.39
Appeals from assessor's omitted assessments may be made to the county board of taxation on or before December 1 of the year of levy or 30 days from the date the collector of the taxing district completes the bulk mailing of tax bills for omitted assessments, whichever is later, and the county board shall hear and determine all such appeals within one month after the last day for filing such appeals, provided, however, that appeals from assessor's omitted assessments may be made directly to the Tax Court on or before December 1 of the year of levy, or 30 days from the date the collector of the taxing district completes the bulk mailing of tax bills for omitted assessments, whichever is later, if the aggregate assessed valuation of the property exceeds $750,000.00. Within ten days of completion of the bulk mailing of tax bills for omitted assessments, the collector of the taxing district shall file with the county board of taxation a certification setting forth the date on which the bulk mailing was completed. Appeals to the Tax Court from the judgment of the county board of taxation shall be made within 45 days from the date fixed for final decisions by the county board of taxation on appeals from assessor's omitted assessments. In all other respects such appeals shall be governed by the laws concerning appeals from real and personal property assessments.
