The City of Florence City Council adopts a tax or millage rate by June 30 of each year for the upcoming fiscal year as part of the annual budget adoption process. The millage rate is applied to the property's assessed value. Real estate property taxes are collected by the Florence County Treasurer's Office and are due by January 15 of each year. Penalties are assessed to owners who do not pay property taxes by the due date each year. Failure to pay could result in forfeiture of property. Bills are mailed to the owner's last known address. It is the taxpayer's responsibility to keep the Florence County Assessor's Office informed of current billing information for real property. Failure to receive a bill does not relieve the taxpayer of responsibility for paying it. For more information, or to notify the office of an address change for your real estate tax bill, contact the Florence County Assessor's Office, located in room 104 of the City-County Complex, Florence, between 8:30 am and 5:00 pm, Monday through Friday, or call the office at 843-665-3056.
