About the Irmo Property Market
Irmo is a city located in Richland County, South Carolina. Every property inside the Irmo city limits is assessed by Richland County Assessor, which applies South Carolina property tax rules uniformly across the county.
Because Irmo property values are set at the county level, the $200,000 county median home value and 0.71% effective tax rate apply to homes throughout the city. Homeowners who believe their Irmo home is over-assessed have the right to file a appeal directly with Richland County Assessor before the 90 days from notice deadline.
South Carolina allows the assessor to defend or adjust the assessed value during a appeal, so Irmo homeowners should build a strong evidence-based case before filing — which is exactly what ProtestMax generates for $45.
Irmo Property Market Context
Every Irmo homeowner operates under South Carolina property tax law, and understanding the state context is the first step toward a successful challenge.
South Carolina market character
South Carolina caps increases from reassessment at 15% over five years, and residential owner-occupied property is assessed at 4% of fair market value. Coastal and upstate markets have appreciated rapidly, producing plenty of over-assessments despite the cap.
How South Carolina handles appeals
South Carolina homeowners appeal to the county assessor, then the county Board of Assessment Appeals, then the Administrative Law Court. The state runs a clear process.
When to file in Irmo
Objections must be filed within 90 days of the assessment notice. Reassessment years produce the heaviest filings.
