Homebuyers moving to South Carolina will find a rather favorable environment for property taxes, particularly for owner occupants.
While the property tax rate set by the state is at 6%, for real property this applies only to investments and second homes – which can offset tax burden through income tax deductions.
An owner occupant however will enjoy a number of advantageous discounts at the property tax level.
There are a number of factors determine the tax assessment of particular real property in South Carolina, including the appraised value, the millage rate in the tax district, and the assessment ratio determined by the status of the home – as either a full time residence or investment/second home.
