South Carolina Property Tax Appeal Deadline 2026: 90 Days from Notice

Updated March 2026

South Carolina provides property owners with a generous 90-day window to appeal their assessment, but there's a catch - you can only appeal during reassessment years, which occur every five years. Knowing whether 2026 is your reassessment year is crucial.

Appeal Window: 90 days from reassessment notice

Key Points:

  • Only in reassessment years
  • Every 5 years by county

  • No appeal in non-reassessment years

2026 Reassessment Counties Include:

  • Charleston County
  • Greenville County

The Bottom Line

South Carolina's 90-day appeal window seems generous, but the five-year reassessment cycle means missing your window costs you five years of overpayments. If 2026 is your reassessment year, don't waste this opportunity.

Classification errors between primary (4%) and secondary (6%) residences offer the easiest wins. Beyond that, hurricane history, coastal changes, and the unique challenges of heirs property create numerous grounds for appeal.

In the Palmetto State, patience between cycles is required - but swift action during your reassessment year is essential.

Critical Note: South Carolina only allows appeals during reassessment years (every 5 years) or after new construction/improvements. You have 90 days from receiving your notice - not from assessment date. First verify 2026 is your reassessment year, then check your classification (4% vs 6%), then build your value case. Miss this window and you wait 5 more years.
