Your property will be identified for tax sale once you are 1 year late in paying your property taxes.
 

The process for your property being sold at a tax sale is governed by South Carolina Code of Laws Section 12-51-40.
 

The tax sale occurs at different times for different counties.  Most counties schedule their tax sale around the beginning of November.
 

There is a 12 month redemption period where you can pay the pay the outstanding property tax amount plus interest of 12% pro-rated quarterly on the bid amount.
 

Following the redemption period, the successful bidder will receive a tax deed for your property and you will no longer have ownership rights to the property.
