Travis BunnTravis Bunn·Updated July 22, 2026

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.

How Dorchester County Assesses Property

4%of market value

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.

2

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.

3

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.

5

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.

6

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.

7

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.

Frequently Asked Questions

What is the deadline to file a property tax appeal in Dorchester County?
You must file your property tax appeal in writing within 90 days from the date your assessment notice was mailed. This deadline is strictly enforced and cannot be extended. If you receive your assessment notice in July, for example, you would have until early October to file your appeal. It's critical not to wait until you receive your actual tax bill to appeal, as the 90-day window begins when the assessment notice is mailed, not when the tax bill arrives. Missing this deadline means you'll have to wait until the next reassessment cycle, potentially five years, to challenge your property's assessed value.
How do I file a property tax appeal online in Dorchester County?
Currently, Dorchester County does not offer a fully online appeal filing system. You must submit your appeal in writing either by mail or in person to the Dorchester County Assessor's Office at 201 Johnston Street, St. George, SC 29477. However, you can access the appeal form on the county's website at www.dorchestercountysc.gov under the Assessor's Office Forms & Documents section. You can also call (843) 563-0162 or (843) 832-0162 to request that an appeal form be mailed to you. While the property search and assessment information are available online, the actual appeal submission requires a written document delivered via mail or in-person.
What is the homestead exemption worth in Dorchester County for 2026?
The South Carolina Homestead Exemption in Dorchester County exempts the first $50,000 of your home's fair market value from property taxes. For eligible homeowners age 65 or older, totally and permanently disabled, or legally blind, this translates to approximately $300 to $430 in annual tax savings depending on your specific millage rate and school district. The exemption removes $50,000 from the assessed value calculation before taxes are applied. For example, if you own a home with an assessed value of $250,000, you would only pay taxes on $200,000. You only need to apply once through the Dorchester County Auditor's Office, and the exemption continues automatically unless your eligibility changes.
How does Dorchester County's 4% assessment ratio work for legal residences?
South Carolina applies a 4% assessment ratio to owner-occupied legal residences, which is significantly lower than the 6% ratio applied to other property types like rental properties or second homes. This means only 4% of your home's fair market value is used to calculate your property taxes. For a home with a market value of $273,000 (the county median), the assessed value would be $10,920 (4% of $273,000), resulting in approximately $1,638 in annual taxes at the county's 0.60% effective rate. Without the legal residence ratio, that same home would have an assessed value of $16,380 (6% of $273,000), costing approximately $2,457 annually. You must apply for this 4% ratio through the Assessor's Office as soon as you move into your home.
What evidence do I need to win a property tax appeal in Dorchester County?
To successfully appeal your property tax assessment in Dorchester County, you need strong comparable sales evidence showing that similar properties in your area sold for less than your assessed value within the past 6 to 12 months. The most compelling evidence includes at least three to five comparable sales of similar homes (same size, age, condition, and neighborhood) that demonstrate your property is overvalued. Additionally, provide clear photographs documenting any property defects, damage, or deferred maintenance that would reduce market value. Repair estimates from licensed contractors for significant issues like roof damage, foundation problems, or needed HVAC replacements can strengthen your case. If you have a recent independent appraisal showing a lower value than the county's assessment, include that as well. The key is proving your property's market value is lower than the county's determination with objective, documented evidence.
How often does Dorchester County conduct property tax reassessments?
Dorchester County conducts countywide property tax reassessments every five years, as required by South Carolina law. The most recent reassessment notices were mailed in 2024, meaning the next countywide reassessment will occur in 2029. During reassessment years, the Assessor's Office reappraises all properties to determine fair market value based on current market conditions. Between reassessment cycles, only new construction, additions, or property improvements are assessed. If you disagree with your reassessed value, you must appeal within 90 days of receiving your assessment notice. The county's five-year cycle means that if you miss your appeal deadline, you may have to wait until the next reassessment to challenge your property's valuation, making it crucial to act quickly when you receive your assessment notice.
Can I appeal my Dorchester County property taxes if my home value has decreased?
Yes, you can absolutely appeal your property tax assessment in Dorchester County if you believe your home's market value has decreased since your last assessment or if the county's assessed value is higher than current market conditions support. This is particularly relevant for homeowners who purchased during market peaks or whose properties have experienced damage, deferred maintenance, or neighborhood decline. You'll need to provide evidence supporting the lower value, such as recent comparable sales showing declining values in your area, documentation of property damage or needed repairs, or a recent independent appraisal. Remember that Dorchester County conducts reassessments every five years, so property values may not reflect current market conditions between reassessment cycles. Your appeal must be filed within 90 days of receiving your assessment notice to be considered.
What happens after I file a property tax appeal in Dorchester County?
After you file your property tax appeal with the Dorchester County Assessor's Office, your case will be reviewed by county appraisers who will examine the evidence you submitted along with their own market data and property records. You may be contacted for an informal meeting or hearing where you can present your case directly to the assessor's staff and answer questions about your evidence. During this meeting, you should be prepared to explain why you believe the assessed value is too high and present your comparable sales data, photographs, and other supporting documentation. The Assessor's Office will then make a determination and notify you in writing of their decision. If they agree with your appeal, your assessed value will be lowered accordingly. If they deny your appeal or offer only a partial reduction, you have the right to further appeal to the South Carolina Administrative Law Court within 30 days of receiving the county's decision.
