Except as otherwise provided in this section, a penalty of 25 percent or five dollars ($5), whichever is greater, shall be added to any portion of the fee for renewal of any license which is required by this division which is not paid by the last day of the month following that in which the preexisting license expired.

A penalty shall not accrue if the licensee operates only seasonally and he has not engaged in the activities for which the license is required between the time his preexisting license expired and the date of the renewal of his license.
