Due dates and times are based on the Treasurer’s main office in Florence hours of operation and observed legal holidays. Satellite offices may be closed. If the delinquency date is a Saturday, Sunday or other legal holiday, the time of delinquency is 5:00 p.m. on the next business day. All taxes bear interest from the time of delinquency at the rate of sixteen per cent per year simple until paid. A fraction of a month is counted as a whole month. Additional fees may apply.
