South Carolina's 4% Assessment Ratio
South Carolina has one of the most favorable assessment ratios for homeowners in the country:

- Owner-occupied residential (legal residence): 4% of market value
- Other residential, commercial: 6% of market value
- Agricultural: 4% of use value
- Manufacturing: 10.5% of market value
This means a home worth $300,000 has an assessed value of just $12,000 for tax purposes. While the 4% ratio keeps the assessed value low, the tax rate (millage) applied to that value can be high, resulting in meaningful tax bills.
To find the implied market value from your assessment, divide by 0.04. If your assessed value is $16,000, the assessor thinks your home is worth $400,000.
Understanding this topic fully means looking at both the big picture and the specific details that apply to your situation. Every property is different, and the strategies that save the most money are the ones tailored to your particular home, location, and circumstances.
Start by gathering the basic facts about your property: its assessed value, the tax rate in your jurisdiction, and any exemptions currently applied. Then compare your situation to what is available. You may find opportunities for savings that you did not know existed.
South Carolina's 5-Year Reassessment Cycle
Each South Carolina county reassesses on a 5-year cycle. Different counties reassess in different years. Between reassessments, values stay the same unless the property changed (new construction, additions, demolition).
The 5-year gap means reassessment jumps can be significant. If home values in your area increased 40% over 5 years, your reassessment notice will reflect that entire increase at once.
The 15% Cap
South Carolina caps reassessment increases at 15% for properties that did not change hands during the reassessment cycle. If your reassessment would increase your value by more than 15%, the increase is phased in over the next cycle.
However, the cap resets when the property transfers. New owners start at the full current market value, which can mean a significant tax increase compared to the previous owner.

How to Appeal in South Carolina
- File with the county assessor within 90 days of the reassessment notice
- Informal review: The assessor reviews your evidence and may agree to adjust
- Board of Assessment Appeals: If the assessor denies your appeal, escalate to the county or state Board of Assessment Appeals
- Administrative Law Court: Further appeals go to the SC Administrative Law Court
The appeal process is designed to be accessible to regular homeowners, not just attorneys and tax professionals. You do not need to hire anyone to file. The key is preparation. Gather your evidence before the hearing, organize it clearly, and practice presenting your case in under 10 minutes. Lead with comparable sales, then cover any property record errors, and finish with photos or documentation of condition issues.
Keep your tone professional and factual. Review boards respond to evidence, not complaints. If you walk in with 3 strong comparable sales and a calm, organized presentation, you are already ahead of most appellants.
South Carolina Exemptions
| Exemption | Benefit | Eligibility |
|---|---|---|
| Legal residence (homestead) | 4% assessment ratio (vs. 6% for non-owner-occupied) | Owner-occupied primary residence |
| Homestead Exemption (65+) | First $50,000 of fair market value exempt from property tax | Age 65+, disabled, or legally blind |
| Disabled veteran exemption | Full exemption on dwelling and up to 1 acre | Permanently and totally disabled veteran |
The senior/disabled homestead exemption ($50,000 off fair market value) is very valuable in South Carolina. At a 4% ratio, it exempts $2,000 of assessed value. Apply with the county auditor.
Do not assume you are automatically enrolled. Most exemptions require an application, and many homeowners lose years of savings simply because they never filed. Contact your county assessor's office or check their website for the application form. Bring proof of eligibility (age verification, disability documentation, veteran status, etc.) and file well before the deadline.
If you qualify for multiple exemptions, apply for all of them. In most jurisdictions, exemptions stack. A senior homeowner who is also a veteran can often claim both exemptions simultaneously, doubling the savings.
Your Next Steps
Here is what to do right now:
- Check your state's deadline. Use the tables above to find your state's specific dates. If your deadline is within the next 60 days, start preparing immediately.
- Open your assessment notice. If you received one recently, read it today. Do not set it aside. Check the assessed value, property details, and the appeal deadline printed on it.
- Gather comparable sales. If your assessed value looks too high, pull 3 to 5 recent sales of similar homes in your area. This is the single most important piece of evidence for any appeal.
- File for exemptions you have not claimed. Many homeowners miss exemptions simply because they never applied. Check what is available in your state and file before the deadline passes.

Frequently Asked Questions
When is my county's next reassessment?
Contact your county assessor's office or check the SC Department of Revenue website. Counties reassess on a 5-year rotation.
Why did my taxes jump when I bought my home?
The 15% reassessment cap does not apply to properties that changed hands. When you buy, the assessment resets to the current fair market value, removing any cap benefit the previous owner had.
What is the difference between "legal residence" and regular residential?
"Legal residence" is your primary, owner-occupied home. It gets the favorable 4% assessment ratio. Other residential properties (rentals, second homes) are assessed at 6%. File the legal residence application with the county assessor.
