How it works
Property tax in Aiken County is based on assessed value rather than full market value. The county assessor determines market or use value and applies an assessment ratio defined under South Carolina law to arrive at assessed value. Local taxing authorities then apply millage rates to the assessed value to estimate annual property tax. This calculator assumes assessed value is already known and applies a combined local rate for estimation.
Examples
If a property has an assessed value determined by the county, that assessed value is multiplied by the combined local millage rate to estimate annual property tax. Different property types use different assessment ratios under state law, which is why this estimate begins with assessed value rather than market value.
Limitations and important notes
Assessment ratios in South Carolina vary by property classification, such as owner-occupied legal residences and other residential or commercial property. Millage rates vary by school district, municipality, and special districts within Aiken County. Exemptions and special assessments can alter assessed value or eligibility and are not modeled here. This calculator provides an estimate only, and actual tax bills may differ.
