The municipal governing body may fix fines and penalties for the violation of municipal ordinances and regulations not exceeding five hundred dollars or imprisonment not exceeding thirty days, or both. If the person or business taxed pays a business license tax to a county or to another municipality where the income is earned, the gross income for the purpose of computing the tax must be reduced by the amount of gross income taxed in the other county or municipality.

For the purpose of providing and maintaining parking for the benefit of a downtown commercial area, a municipality may levy a surtax upon the business license of a person doing business in a designated area in an amount not to exceed fifty percent of the current yearly business license tax upon terms and conditions fixed by ordinance of the municipal council. The area must be designated by council only after a petition is submitted by not less than two-thirds of the persons paying a business license tax in the area and who paid not less than one-half of the total business license tax collected for the preceding calendar year requesting the designation of the area. The business within the designated area which is providing twenty-five or more parking spaces for customer use is required to pay not more than twenty-five percent of a surtax levied pursuant to the provisions of this paragraph.
