(a) All taxes due under this article shall be settled by the department, and such settlement shall be subject to audit and approval by the Department of the Auditor General, and shall, so far as possible, be made so that notice thereof may reach the taxpayer within eighteen months after the tax report was required to be made. The Secretary of Revenue, after consultation with the Auditor General, may develop and implement procedures for the settlement of taxes employing, among other means, automatic data processing, statistical analysis, computer analysis, mechanical handling and issuance of settlement documents, including documents without original signatures, such that will facilitate what he determines to be the most efficient and productive use of the resources within his control required to adequately and reasonably ensure the proper collection of taxes. The Secretary of Revenue shall provide documentation of such procedures to the chairmen of the Appropriations Committee and the Finance Committee of the Senate and of the House of Representatives.

(b) If, within a period of three years after the date of any settlement, the department is not satisfied with such settlement, or if at any time the net income as returned by any corporation to the Federal Government is finally changed or corrected by the Commissioner of Internal Revenue or by any other agency or court of the United States with the result that tax, in addition to the amount paid, is due under this article, the department is hereby authorized and empowered to make a resettlement of the tax due by such corporation, based upon the facts contained in the report, or upon any information within its possession or that shall come into its possession.

Whenever a resettlement shall have been made hereunder, the department shall resettle the account according to law and shall credit or charge, as the case may be, the amount resulting from such resettlement upon the current accounts of the corporation with which it is made.

The resettlement shall be subject to audit and approval by the Department of the Auditor General as in the case of original settlement, and in case of the failure of the two departments to agree, the resettlement shall be submitted to the Board of Finance and Revenue as in the case of original settlements.

(c) Promptly after the date of any such settlement, the department shall send, by mail or otherwise, a copy thereof to such corporation. The tax, interest, and penalty imposed by this article shall be subject to the right of resettlement, review, and refund within the time and in the manner now or hereafter provided for by law for petitions for resettlement, review and refund and to the right of appeal in the manner now or hereafter provided for by law for appeals in the case of tax settlements.

(d) If any corporation shall neglect or refuse to make any report and payment of tax required by this article, the department shall estimate the tax due by such corporation and subject to audit and approval by the Department of the Auditor General, settle the amount due by it for taxes, penalties, and interest thereon as prescribed herein, from which settlement there shall be no right of review or appeal, but the department, with the approval of the Department of the Auditor General, may require a report to be filed, and thereupon make a settlement based upon such report and cancel the estimated settlement.
