HAR § 18-235-111 — Limitation period for assessment, levy, collection, or credit

(a) Tax imposed under chapter 235, HRS, shall be assessed or levied, and any overpayment shall be credited, within three years after filing the final income tax return for the taxable year, or within three years of the prescribed due date of the return, whichever is later. (1) Running of the limitation period. (A) In general. Although returns may be filed before the prescribed due date, the running of the limitation period for purposes of section 235-111, HRS, and this section, unless otherwise prescribed, does not start until after the prescribed due date for filing. (B) Where an amended return is filed. When a return has been timely filed as required by law and thereafter an amended return is filed, the limitation period begins to run from the date the original return was filed or the prescribed due date, whichever is later. Filing an amended return does not extend, nor does it stop, the running of the limitation period. The original return, however, must be complete and meet the statutory requirements; the limitation period will begin to run only upon the filing of a proper return. The running of the limitation period is not affected or suspended by the later filing of amended returns. (C) Loss of S corporation status. Where corporate tax liability is found to be due upon a determination that the corporation is not entitled to the benefits of a corporation organized under subchapter S (sections 1361 to 1369) of the Internal Revenue Code of 1986, as amended, the limitation period for assessment and collection shall run from the date the return is filed or from the prescribed due date for filing the return, whichever is later. (2) Credit resulting from net operating loss carrybacks. As set forth in section 235-111, HRS, the limitation period for credit related to an overpayment of tax resulting from a net operating loss carryback shall be the later of: (A) Three years from the prescribed due date for filing the return for the taxable year in which the net operating loss occurs; or HRS §235-110.7 HRS §235-111
