Richland County mailing notices for property value changes
June 17, 2026
Notifications are not tax bills; use online application for appeals
Richland County is giving many property owners an early heads up about changes to the value of their property for 2026. Next week, the County Assessor’s Office is sending notifications by mail to owners of properties whose values have changed by at least $1,000.
More than 13,600 property owners will receive the notices by mail beginning Tuesday, June 23.
Law requires the County assessor to assess all taxable property at market value. Three factors can cause property values to increase or decrease:
- an Assessable Transfer of Interest (ATI)
- new construction (built in 2025)
- physical changes, such as additions or renovations, that were completed in 2025
While the taxable value on these notices is the basis for the County’s real property tax bill, the taxes will not be calculated until October, when County Council sets the property tax rates, known as the millage rate.
Residents can visit the Richland County Assessor’s Property Value and Tax Estimate Inquiry page: https://bit.ly/RC-Property25, to estimate their real property taxes based on the 2026 taxable value and the 2025 millage rate. The link to this site is also under the Property & Business tab at www.richlandcountysc.gov.
For the most recent millage rates, visit the County Auditor online: www.richlandcountysc.gov/Auditor.
Filing an Appeal
Property owners who disagree with their appraisal have until Sept. 21 to file an appeal. Richland County encourages property owners to use the online appeal application to submit appeals. Find instructions on the Assessor’s website or on the back page of the mailed notice about the property value change.
The Assessor’s Office ensures all real property is valued at its current fair market rate, which is the price the property could sell for in the open real estate market. Legal residences in the state are assessed for taxes at 4 percent, while commercial or non-owner-occupied property is assessed at 6 percent.
While the County’s appraisers work diligently to accurately value property, County Assessor Fred Descy encourages property owners to check their notices for accuracy.
