N.J. Stat. § 54:4-63.11
Appeals from added 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 added assessments, whichever is later, and the county board of taxation shall hear and determine all such appeals within one month after the last day for filing such appeals; provided, however, that appeals from added 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 added assessments, whichever is later, if the aggregate assessed valuation of the property exceeds $750,000.00. Within ten days of the completion of the bulk mailing of tax bills for added 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 added assessments. In all other respects such appeals shall be governed by the laws concerning appeals from real property assessments.
