In 2025, Fort Mill property taxes remain relatively low compared to national averages, but rates vary by county and specific location. The median effective property tax rate in Fort Mill is 0.65% to 0.81%, depending on whether your property is located in Lancaster or York County—the two counties covering parts of Fort Mill. The median Fort Mill home value is approximately $325,600 for Lancaster County and $322,743 for York County, with typical annual tax bills ranging from about $2,215 to $2,626 based on assessed value and exemptions.
Owner-occupied residences are assessed at a lower rate (around 4% of market value) compared to non-primary or commercial properties, which are assessed at 6%. Your final tax bill is calculated from the assessed value (a percentage of market value after exemptions) times the local mill rate, expressed in “mills” (each mill is $1 per $1,000 of assessed value). Fort Mill’s rates are below the South Carolina average, and exemptions—such as the homestead exemption for seniors—can reduce taxes further.
Property owners in Fort Mill should review their annual assessments for accuracy and consider appeals if values seem excessive. Discrepancies and mistakes can often be corrected, potentially lowering your bill. The wide range in tax bills and home values across Fort Mill highlights the importance of understanding how local rates, assessment practices, and exemptions affect your final costs.
