Property Taxes in South Carolina
South Carolina's property taxes are a genuine, well-corroborated relocation positive at the statewide level -- roughly 0.51% effective on owner-occupied housing, well below the national average -- built on a real, filing-dependent 4%-versus-6% assessment-ratio system this record states plainly rather than assuming applies automatically.

Learn moreThe 4%-versus-6% assessment-ratio mechanic, precisely
South Carolina taxes real property based on a percentage of fair market value called the assessment ratio, not the full market value itself. Owner-occupied primary residences that have filed for "legal residence" status (SC Code Section 12-43-220) are assessed at 4% of fair market value; nearly all other real property -- second homes, rental property, most commercial property -- is assessed at 6%. This is a real, independently verified mechanic confirmed via county-government sources this pass, not part of south-carolina.js's original metricSources research -- confirm current filing procedures and deadlines directly with your county assessor.
You must actively file for the 4% rate -- it is not automatic
New owners must apply for the owner-occupied legal-residence classification with their county assessor; the 6% rate applies by default until that filing is processed. This is a genuinely easy step to miss during a move and one this record flags explicitly rather than assuming buyers already know to do.
A separate $50,000 exemption exists for seniors, the disabled, and the blind
South Carolina separately offers a $50,000 homestead exemption against the taxable value of an owner-occupied legal residence for homeowners who are 65+, permanently disabled, or legally blind (SC Code Section 12-37-250) -- confirmed via county-government sources this pass. This program is distinct from, and layered on top of, the 4% legal-residence assessment ratio (a qualifying homeowner must already hold 4% legal-residence status to claim it); confirm current eligibility and application deadlines directly with your county auditor.
The statewide average masks real, if less-certain, county-level variation
South Carolina's roughly 0.51% statewide average effective rate on owner-occupied housing value (Tax Foundation, 2026) sits well below the roughly 0.91% national average -- one of the lower rates in this dataset. County-level figures cited by one aggregator range from roughly 0.36% in Calhoun County to roughly 0.71% in Bamberg County, but south-carolina.js's own research flags that specific range as low-confidence, sourced from a single secondary aggregator rather than independently verified against the SC Dept. of Revenue or individual county assessors -- confirm your specific target county's current millage rate directly.
Key takeaways
- South Carolina assesses owner-occupied primary residences at 4% of fair market value versus 6% for most other real property (SC Code Section 12-43-220) -- a real, filing-dependent mechanic, not an automatic discount.
- File for the owner-occupied "legal residence" classification with your county assessor promptly after closing -- the 6% rate applies by default until processed.
- A separate $50,000 homestead exemption exists for owners 65+, permanently disabled, or legally blind who already hold 4% legal-residence status (SC Code Section 12-37-250) -- confirm eligibility with your county auditor.
- South Carolina's roughly 0.51% statewide average effective rate runs well below the national average, though this dataset's own county-level range (0.36%-0.71%) is flagged low-confidence -- confirm your specific county directly.
