Aiken County property taxes in 2025 maintain a median effective rate of 0.48% to 0.59%, significantly below the South Carolina median of 0.66% and national average of 1.02%, resulting in a typical annual bill around $442–$606 for median home values near $71,607–$125,000.​
Tax Calculation and Rates
Property taxes are based on assessed value (often lower than market due to exemptions), multiplied by the millage rate set by local entities like Aiken city (median 0.42%, ranging 0.28%–1.50% across percentiles). The county assessor determines fair market value annually, with 2025 updates reflecting recent appraisals; bills are mailed in late September/early October and due by January 15, 2026.​
Exemptions and Relief
Homeowners qualify for homestead exemption (up to $50,000 off assessed value for owner-occupied primary residences), senior (65+) exemption (additional 25%–100% based on income), and disability exemptions reducing taxable value. Apply via the Aiken County Auditor’s office before deadlines, typically by July 15 for the next fiscal year.​
Payment and Appeals
Pay online, by mail, or in-person at the Aiken County Treasurer; late payments incur 3% penalty plus 1% monthly interest. Appeal assessments by September 15 if overvalued, using evidence like appraisals. Check aiken.county.sc.gov for personalized bills and rates.
