What This Data Tells Us About Appeals in South Carolina
In South Carolina, property tax appeals are filed with the County Assessor / Administrative Law Court. The typical window is Within 90 days of the assessment notice, with the deadline most commonly falling in November. Filing fees reported for this state are $0, and Lincoln Institute research plus state-reported data suggest roughly 45% of appeals result in some reduction when supported by comparable sales or documented errors.
South Carolina's 15% cap limits assessment increases between reappraisals for owner-occupied homes. If your cap is being applied incorrectly, that's a valid appeal basis. Appeals are driven by the gap between a parcel's assessed value and its actual market value — the calculator below turns that gap into an annualized dollar figure at your effective tax rate. The strongest evidence is three to five arms-length comparable sales from the past six to twelve months, plus documentation of any factual errors in the assessor's record (square footage, bedroom count, finished-basement status).
