Dorchester County Property Tax Appeal, South Carolina
Dorchester County is located in South Carolina's Lowcountry region, with St. George serving as the county seat and Summerville and North Charleston as major population centers. As of the 2020 census, the county had a population of 161,540, making it one of the fastest-growing areas in the state. Property tax appeals are particularly important in Dorchester County given the county's rapid growth and rising property values, which can lead to assessment increases during the county's five-year reassessment cycles. The median home value in Dorchester County is approximately $273,000, significantly higher than the state median of $137,500, which makes accurate assessments crucial for homeowners.

On the typical Dorchester County home, valued near $273,000 at the county’s effective tax rate of 0.60%, an over-assessment of even 10% means you are overpaying year after year until you appeal it. Here is how to find out if yours qualifies.
2026 Appeal Deadline: Within 90 days of the mailing date of the assessment notice
You must file your written appeal within 90 days from the date the assessment notice was mailed to you. This deadline is strictly enforced, and appeals filed after the 90-day window will not be accepted. Do not wait until your tax bill arrives to file your appeal, as it may be too late by then.

How Dorchester County Assesses Property
Assessed by: Dorchester County Assessor's Office
Assessment cycle: Every 5 years (quinquennial reassessment)
Notices typically mailed: Summer (typically July-August during reassessment years)
In South Carolina, your property's assessed value is calculated by applying a 4% assessment ratio to the fair market value if your home qualifies as your legal residence. For example, if your home's market value is $273,000 (the county median), your assessed value would be $10,920 ($273,000 x 4%). At Dorchester County's effective tax rate of 0.60%, this would result in approximately $1,638 in annual property taxes. Without the legal residence 4% ratio, the assessment ratio increases to 6%, significantly increasing your tax bill.
The Appeal Process
Appeals are heard by the County Assessor. After filing your appeal, the Assessor's Office will review your evidence and may schedule an informal meeting to discuss your concerns. You should be prepared to present comparable sales data, photographs, and other documentation supporting your position that the assessed value is too high.
Step 1: Review your assessment notice carefully within 90 days of receiving it. Compare the assessed market value to recent sales of comparable properties in your neighborhood and document any discrepancies or errors in the property description.
Step 2: Gather supporting evidence for your appeal, including recent comparable sales data (properties sold within the last 6-12 months), photographs showing property condition or defects, repair estimates for any significant issues, and a recent independent appraisal if available.
Step 3: Complete the Appeal Form available on the Dorchester County Assessor's website or submit a written letter of disagreement. Your appeal must include your name, property address, TMS number, the assessment value you're challenging, and your evidence supporting a lower valuation.
Step 4: File your appeal in writing within 90 days of the assessment notice mailing date. Submit it by mail to 201 Johnston Street, St. George, SC 29477, or deliver it in person to the Assessor's Office. Keep copies of all documents for your records.
Step 5: The Assessor's Office will review your appeal and may schedule an informal meeting to discuss your evidence. You will have the opportunity to present your case, including comparable sales data and documentation of property conditions that support your position.
Step 6: If the informal review does not resolve your appeal satisfactorily, your case will be heard by the County Assessor, who will make a determination. You will receive a written decision explaining whether your assessment was adjusted and the reasoning behind the decision.
Step 7: If your appeal is denied at the county level, you can appeal to the South Carolina Administrative Law Court within 30 days of receiving the county's decision, or ultimately to circuit court if necessary.
Required form: Appeal Form (available on county website) or written letter of disagreement
