(a) If the taxpayer has failed to file a return, or if the Tax Collector is not satisfied with the return and payment of the amount of tax required, and additional taxes are determined by the Tax Collector to be due, the Tax Collector shall deliver written notice of his determination of a deficiency to the taxpayer, and such deficiency, plus penalties and interest, shall be due and payable forty-five (45) days after receipt of the notice and demand. Such additional taxes shall bear any applicable civil penalties and interest as provided in Section ___-540, and every such notice of a determination of an additional amount due shall be assessed within the limitation period provided in Section ___-550.
(1) When a return is filed. If the Tax Collector is not satisfied with a return and payment of the amount of tax required by this Chapter to be paid to the City, he may examine the return or examine the records of the taxpayer, and redetermine the amount of tax, penalties, and interest required to be paid, for any periods available to the Tax Collector under Section ___-550, based upon the information contained in the return or records or based upon any information within his possession or which comes into his possession.
(2) When no return is filed. If any person fails to make a return, the Tax Collector may make an estimate of the amount of tax due under this Chapter and compute any applicable penalties and interest due, based upon any information within his possession or which comes into his possession.
(b) Estimates by the Tax Collector. Any estimate made by the Tax Collector is to be made on a reasonable basis. The existence of another reasonable basis of estimation does not, in any way, invalidate the Tax Collector's estimate. It is the responsibility of the taxpayer to prove that the Tax Collector's estimate is not reasonable and correct, by providing sufficient documentation of the type and form required by this Chapter or satisfactory to the Tax Collector.
