Property Taxes in South Carolina: Rates, Exemptions, and How They Work (2026)
TL;DR
South Carolina assesses owner-occupied homes at just 4% of market value, one of the lowest assessment ratios in the country. Non-owner-occupied property is assessed at 6%. Reassessment happens every 5 years, with the assessment capped at 15% increase over any 5-year period for owner-occupied homes (unless a sale triggers reassessment to market value). The average effective rate is about 0.53%. Appeal within 90 days of the assessment notice to the county assessor, then the county Board of Assessment Appeals.
On a $300,000 home, the assessed value is just $12,000 (4%). Below, we cover property Taxes in South Carolina: Rates, Exemptions, and How They Work (2026) in full.
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.
Assessment Ratios
| Property Type | Assessment Ratio |
|---|---|
| Owner-occupied residential | 4% |
| Other residential, commercial | 6% |
| Agricultural (private) | 4% |
| Manufacturing | 10.5% |
| Utility | 10.5% |
On a $300,000 home, the assessed value is just $12,000 (4%). With a typical mill rate of 250-350, the annual tax would be $3,000-$4,200.
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.
15% Cap
For owner-occupied properties, the assessed value cannot increase by more than 15% over any reassessment cycle (5 years). The cap resets when the property is sold, at which point it is reassessed at the sale price.

Exemptions
| Exemption | Benefit | Who Qualifies |
|---|---|---|
| Homestead Exemption | First $50,000 of market value exempt from school operating taxes | Owner-occupied, SC legal resident |
| Senior/Disabled | Additional exemption from school taxes on first $50,000 | 65+ or disabled, varies by county |
| Disabled Veterans | Full exemption for permanently disabled | Service-connected permanent total disability |
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.

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.
Your Next Steps
Here is exactly what to do this week to start lowering your South Carolina property taxes:
- Pull your property record card. Contact your county assessor's office or check their website. Compare every detail to your actual property. Flag anything that looks wrong.
- Check recent sales in your neighborhood. Look up 3 to 5 homes similar to yours that sold in the past 12 months. If they sold for less than your assessed value, you have a case.
- File for any exemptions you have not claimed. If you are a senior, veteran, or disabled homeowner in South Carolina, there may be exemptions saving you hundreds or thousands per year that you have not applied for yet.
- Mark your appeal deadline. Find the date on your most recent assessment notice and set a reminder for two weeks before. Do not let the deadline pass without acting.
Applying This in South Carolina
South Carolina homeowners face an effective property tax rate of about 0.57%. On a $300,000 home, that translates to roughly $1,709 per year. Even a modest reduction in assessed value creates meaningful annual savings that compound year over year.
In South Carolina, the appeal process goes through the county Assessor and Board of Assessment Appeals. The process is designed to be accessible to homeowners without professional representation. You file a petition, present your evidence (comparable sales are the strongest tool), and receive a decision. Most appeals are resolved within a few months of filing.
If you have not reviewed your South Carolina assessment recently, now is the time. Pull your property record card, check for errors, compare your assessed value to recent neighborhood sales, and file for any exemptions you qualify for. The combination of these steps can reduce your tax bill significantly without spending a lot of time or money.
Why Acting Now Matters in South Carolina
Every month you delay is money lost. Property taxes are assessed annually, and once the tax year begins, you are locked in at your current assessed value unless you file an appeal. There is no retroactive correction for years when you overpaid but did not challenge the assessment.
In South Carolina, the appeal window is limited. Once it closes, you wait a full year for your next opportunity. Homeowners who act promptly after receiving their assessment notice have the best outcomes because they have the most time to gather evidence, review comparable sales, and prepare a clear case.
If you are reading this and your current assessment notice is sitting unopened, go read it now. That single step puts you ahead of the majority of homeowners who never check their assessments at all.
