Berkeley County Property Tax Appeal, South Carolina

Travis BunnTravis Bunn·Updated July 22, 2026

Berkeley County is located in South Carolina's Lowcountry and is part of the Charleston metropolitan area. With the county seat in Moncks Corner and its largest community being Goose Creek, Berkeley County has experienced rapid growth, with a 2026 population estimated at 283,340. The county's median home value of approximately $253,100 is significantly higher than older estimates, and property owners pay an effective tax rate of 0.51%, well below both the state median of 0.66% and the national median of 1.02%. Property tax appeals are particularly relevant here given the county's robust growth and the 2024 countywide reassessment, which may have significantly increased some property values.

On the typical Berkeley County home, valued near $253,100 at the county’s effective tax rate of 0.51%, 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: July 31, 2026 (90 days from the date assessment notices are issued) OR January 15, 2027 if no notice was received

If you receive an assessment notice showing a value increase of $1,000 or more, you have 90 days from the date the notice is issued to file an informal appeal. Assessment notices are typically mailed in spring (April-May), making the 2026 deadline July 31, 2026. If no assessment notice is received, property owners may file an appeal anytime before January 15th (the last day to pay taxes without penalty) for that tax year.

How Berkeley County Assesses Property

4%of market value

Assessed by: Berkeley County Real Property Services Office

Assessment cycle: Five years (quinquennial reassessment)

Notices typically mailed: April-May (notices sent by July 1 or shortly thereafter)

Berkeley County assesses properties at fair market value, then applies South Carolina's 4% assessment ratio for owner-occupied residential property to calculate the assessed value used for taxation. For example, if your home's market value is $350,000, at South Carolina's 4% assessment ratio your assessed value would be $14,000 ($350,000 x 0.04), resulting in approximately $1,785 in annual taxes at the county's effective rate of 0.51%. The most recent countywide reassessment was implemented in 2024, with market values reflecting December 31, 2023.

The Appeal Process

Appeals are heard by the County Assessor. After filing your appeal, you'll first go through an informal review with a certified county appraiser, either by phone or in-person conference. If unresolved, you can escalate to a formal hearing before the County Board of Assessment Appeals, where you'll present evidence and testimony to support your requested value reduction.

1

Step 1: File a written appeal request within 90 days of receiving your assessment notice (or by January 15 if no notice was received). Submit online through the OneBerkeley Portal at portal.berkeleycountysc.gov or mail the Informal Appeal Request Form to the Berkeley County Real Property Services Office. Include your property's Tax Map Number (TMS), property address, and supporting documentation such as comparable sales or photos.

2

Step 2: Informal Review - A certified appraiser from the Assessor's office will conduct an informal review of your appeal. You may be contacted by telephone or scheduled for a conference to discuss your concerns and present evidence supporting your position.

3

Step 3: Receive Notice of Decision - The County Assessor will mail you a written notice of their decision on your informal appeal. If the Assessor agrees with your position, the assessment will be corrected. If not, the notice will explain their determination.

4

Step 4: Appeal to County Board of Assessment Appeals - If you disagree with the Assessor's decision, you must file a written protest with the County Board of Assessment Appeals within 30 days of the notice of decision date. The Board will schedule a hearing where both you and the Assessor present evidence. You must exchange witness and evidence lists at least 15 days before the hearing.

5

Step 5: Board Hearing - Attend the County Board of Assessment Appeals hearing and present your evidence, including comparable sales, appraisals, photos, and documentation of property defects. The Board will issue a written decision within 15 days affirming, increasing, or decreasing your assessment.

6

Step 6: Appeal to Administrative Law Court - If you're unsatisfied with the County Board's decision, you may request a contested case hearing before the South Carolina Administrative Law Court within 30 days of the Board's written decision.

7

Step 7: Further Appeals - Decisions from the Administrative Law Court may be appealed to Circuit Court, the South Carolina Court of Appeals, or ultimately the South Carolina Supreme Court by either party.

Frequently Asked Questions

What is the deadline to appeal my property taxes in Berkeley County for 2026?
The deadline to appeal your Berkeley County property tax assessment is 90 days from the date you receive your assessment notice, which is typically July 31, 2026 for notices mailed in spring 2025. Assessment notices are sent only if your property value increased by $1,000 or more due to new construction, sales, renovations, or other changes. If you did not receive an assessment notice but believe your property is overvalued, you can file an informal appeal anytime before January 15, 2027, which is the last day to pay taxes without penalty. Missing the deadline means you must wait until the following tax year to appeal.
How do I file a property tax appeal online in Berkeley County?
Berkeley County offers online appeal filing through the OneBerkeley Portal at portal.berkeleycountysc.gov. You'll need to create a free account first if you don't already have one. Once logged in, complete the Informal Appeal Request form and attach supporting documentation such as comparable sales data, photos of property defects, or a professional appraisal. Make sure to include your property's Tax Map Number (TMS) and address. The online system allows you to track your appeal status and receive notifications throughout the process. Alternatively, you can mail or hand-deliver your appeal to the Real Property Services Office at 1003 Highway 52, Moncks Corner, SC 29461.
How much is the Homestead Exemption worth in Berkeley County?
Berkeley County's Homestead Exemption removes the first $50,000 from your home's fair market value before calculating property taxes, which can save you approximately $255 per year at the county's 0.51% effective tax rate. To qualify, you must be age 65 or older, totally and permanently disabled, or legally blind as of December 31 preceding the tax year. You also must own and occupy the property as your primary residence and have been a legal South Carolina resident for at least one year. You only need to apply once at the Berkeley County Auditor's Office, and the exemption continues automatically unless your circumstances change, such as selling the property or no longer using it as your primary residence.
What evidence do I need to file a successful property tax appeal in Berkeley County?
The most effective evidence for a Berkeley County property tax appeal includes comparable sales of similar homes in your neighborhood that sold for less than your assessed value within the past 6-12 months, demonstrating that your property is overvalued. You should also gather a professional independent appraisal if possible, photographs documenting any property defects or damage, contractor estimates for needed repairs, and your property record card from the county showing the characteristics used in the assessment. Berkeley County appraisers particularly value recent comparable sales data since the county's assessments reflect market value as of December 31, 2023. Make sure your comparables are truly similar in size, age, condition, and location to strengthen your case during the informal review or Board hearing.
What happens after I file my property tax appeal in Berkeley County?
After filing your informal appeal, a certified appraiser from the Berkeley County Assessor's office will conduct a review of your property and the evidence you submitted. You may be contacted by phone or scheduled for an in-person conference to discuss your concerns and present additional documentation. The Assessor will then mail you a written Notice of Decision explaining whether your assessment will be adjusted. If the Assessor agrees with your position, your assessment will be corrected and you're done. If the Assessor denies your appeal or offers an insufficient reduction, you have 30 days from the Notice of Decision to file a written protest appealing to the County Board of Assessment Appeals, which will schedule a formal hearing where you can present testimony and evidence.
When was Berkeley County's last reassessment and how does it affect my appeal?
Berkeley County completed its most recent countywide reassessment in 2024, with property values reflecting the market as of December 31, 2023. South Carolina law requires counties to reassess all properties every five years, with the next reassessment scheduled for 2029. This means your 2026 property assessment is based on December 31, 2023 market conditions, and any inflation or market changes occurring after that date cannot legally be considered when the county reviews your value. If you purchased your home after December 31, 2023, or if comparable sales show your property was worth less on that specific date, this provides strong grounds for an appeal. Properties that sold or transferred after the 2024 reassessment may have been individually reappraised at current market value through an Assessable Transfer of Interest (ATI).
Can I appeal my Berkeley County property taxes if I didn't receive an assessment notice?
Yes, you can still appeal your Berkeley County property taxes even if you didn't receive an assessment notice. Assessment notices are only sent when a property's value increases by $1,000 or more due to new construction, sales (Assessable Transfer of Interest), renovations, loss of legal residence status, or other changes. If you received no notice but believe your property is overvalued compared to similar homes, you may file an Informal Appeal Request anytime between January 1 and January 15 (the last day to pay without penalty) of the following year. File online through the OneBerkeley Portal at portal.berkeleycountysc.gov or contact the Real Property Services Office at (843) 719-4061 to request the appeal form. Be prepared to provide comparable sales evidence and documentation supporting your claim of overvaluation.
How much can I save by appealing my Berkeley County property taxes?
Successful property tax appeals in Berkeley County save homeowners an average of $462 per year according to recent data. However, your actual savings depend on how much your assessment is reduced and your property's millage rate. For example, if you successfully reduce your home's market value by $50,000, at Berkeley County's 4% assessment ratio this lowers your assessed value by $2,000, resulting in approximately $102 in annual tax savings at the county's 0.51% effective rate. Larger reductions yield greater savings, a $100,000 market value reduction could save you approximately $204 annually. These savings recur every year until the next reassessment, so a successful appeal provides ongoing financial relief. Given that approximately 25% of homes are overassessed, it's worth reviewing your assessment if your home's value seems high compared to recent sales of similar properties.
