Tax collector to notify holder of expiration of license

The tax collector shall mail to each privilege taxpayer holding a license, on or before the first day of the month prior to the month in which his privilege license will expire, a notice that the license will expire and that a new privilege license must be procured during the following month, and shall enclose therewith an application blank for a new license; but the failure to send or receive such notice shall not exempt such privilege taxpayer from any penalties prescribed by law.
