No late charges shall accrue for taxes due and payable on July 1 if received by the municipality on or before the close of business on August 14 immediately following. In the event that August 14 is a non-business day, then no late charges shall accrue if the taxes are received before the close of business on the next business day. The Commission shall provide a tax payment schedule by ordinance for municipal taxes paid after August 14, or the following business day, as the case may be, including the late charges to be added in amounts permitted by state law.
