How Property Tax Works

Richland County, South Carolina operates on an annual property tax system that funds essential county services including schools, public safety, infrastructure, and local government operations. Property taxes are calculated based on assessed values, which are determined at 6% of fair market value for residential properties (or 4% with the Legal Residence exemption). The county reassesses all properties every five years to ensure current market values are reflected.

The effective property tax rate in Richland County varies significantly by location within the county due to multiple special taxing districts, including school districts, fire districts, and municipal boundaries. Property owners should expect their actual tax rate to differ based on their specific address and the combination of taxing entities that serve their area. Most tax credits and exemptions require annual application and are not automatically applied to your property tax bill.

Supplemental Tax Bills

Supplemental taxes in Richland County are additional property tax bills issued when there are mid-year changes to property ownership, value, or use. Common triggers include new construction completion, property transfers that remove existing exemptions, or significant improvements that increase assessed value. The Bailey Bill provides special assessment opportunities for historic property rehabilitation projects.

Supplemental taxes are calculated by applying the current year's tax rate to the change in assessed value, prorated for the portion of the tax year remaining after the change occurs. For example, if a $100,000 home addition is completed in January, you would owe supplemental taxes on that additional assessed value for the full tax year. These supplemental bills are issued separately from your annual tax bill and have their own payment deadlines.

Escrow & Property Taxes

Most homeowners with mortgages have property taxes collected through an escrow account managed by their lender. Your mortgage servicer estimates annual property tax costs, divides by 12, and collects this amount with your monthly mortgage payment. The lender then pays your property taxes directly to Richland County when they become due.

Richland County property taxes are due in two installments, typically in June and December, with the entire annual bill due by September 30th of the following year. If you have an escrow account, verify that your lender has current tax information and is making payments on time, as you remain ultimately responsible for tax payment even when using escrow. For payment verification, account management, and to set up the monthly payment option available for 2025 and 2026, visit the Richland County Treasurer's Office at https://www.richlandcountysc.gov/Government/Departments/Treasurer-s-Office.

Q: What tax credits are available and do I need to apply? A: The Legal Residence exemption reduces assessment from 6% to 4% and exempts school operating millage.
