City taxes shall be due on the first day of July of each year. The treasurer shall not be required to call upon the persons named in the city tax roll, nor to make personal demand for the payment of taxes, but he/she shall give notice to the taxpayers of the city, at least ten (10) days prior to the due date of such taxes of each year, of the time when said taxes will be due for collection by publication, at least once, in one or more of the newspapers published or circulated in the City, or shall give such notice by first class mail addressed to the owners of the property upon which taxes are assessed according to the names of such owners and their addresses as indicated on the tax roll, which notice shall be deemed sufficient for the payment of all taxes on said tax roll. Such notice shall also state that payments of taxes may be made to him/her at any time up to and including the 31st day of August without penalty and that an addition of three and three-fourths (3.75%) percent shall be made on the first day of September and three-fourths percent (.75%) on the first day of each month thereafter that the tax remains unpaid until returned to the county treasurer by the city treasurer. Failure on the part of the treasurer to give said notice shall not invalidate the taxes on said tax roll nor release the person or property assessed from the penalty provided in this chapter in case of non-payment of the same.
