Understanding South Carolina's Assessment Ratio

4%
4% of fair market value (owner-occupied)

South Carolina uses a 4% assessment ratio, meaning your assessed value is set at 4% of your property's estimated market value.

To find your implied market value: Divide your assessed value by 0.04.
Example: Assessed value of $10,360 ÷ 0.04 = $259,000 implied market value

⚠ Common Mistake: Never compare your assessed value directly to comparable sale prices in South Carolina. Always convert to implied market value first.

South Carolina's assessment ratio study

How closely South Carolina assessors' values actually track real sale prices — and whether you can use that in an appeal.

Usable as supporting evidence

County Ratio Study (conducted but not published)

With no published study, build the equivalent argument from the county's own assessment roll, or FOIA SCDOR for the county's findings. In practice South Carolina's 15% reassessment cap and the 4% owner-occupied ratio are the more productive levers.

Supplemental, Escape & Corrected Bills in South Carolina

South Carolina issues no supplemental bills; the December 31 status controls the next tax year, and a sale triggers an ATI reassessment effective the following year rather than a mid-year bill. Omitted property can be back-billed a maximum of 3 prior years.

Omitted property / back-tax charge (property omitted from duplicate)

Assessor discovers real estate, a new structure, addition, or improvement that was omitted from the tax duplicate or never returned/appraised; auditor charges current-year taxes plus taxes for prior escaped years.

Appeal window: Written objection/protest within 90 days of the assessment notice under the S.C. Revenue Procedures Act (S.C. Code 12-60-2510 et seq.), then county board of assessment appeals and Administrative Law Court.90 days

Auditor correction / abatement of errors

Excessive/invalid assessment, officer errors, wrong tax district, or damage from fire/flood/hurricane/wind (valuation adjustment on application).

Appeal window: Correction must generally be requested before the tax is paid; disaster-damage adjustment applications must also precede payment.
