N.C. Gen. Stat. § 105-241.12 — Result when taxpayer does not request a review

(a) Refund. - If a taxpayer does not file a timely request for a Departmental review of a proposed denial of a refund, the proposed denial is final and is not subject to further administrative or judicial review. A taxpayer whose proposed denial becomes final may not file another amended return or claim for refund to obtain the denied refund. (b) Assessment. - If a taxpayer does not file a timely request for a Departmental review of a proposed assessment, the proposed assessment is final and is not subject to further administrative or judicial review. Upon payment of the tax, the taxpayer may request a refund of the tax. Before the Department collects a proposed assessment that becomes final when the taxpayer does not file a timely request for a Departmental review, the Department must send the taxpayer a notice of collection. A notice of collection must contain the following information: (1) A statement that the proposed assessment is final and collectible. (2) The amount of tax, interest, and penalties payable by the taxpayer. (3) An explanation of the collection options available to the Department if the taxpayer does not pay the amount shown due on the notice and any remedies available to the taxpayer concerning these collection options.
