Property tax rates in Anderson County, SC run from roughly 249 mills to 419 mills in total, depending on which tax district your property sits in. What you actually owe comes from three numbers multiplied together: the fair market value the county assigns your property, an assessment ratio tied to how the property is used (4% for a primary residence, 6% for most everything else), and the combined millage rate for your district. Two houses with identical market values can produce very different bills once those factors interact.
Assessment Ratios: The 4% vs 6% Split
South Carolina taxes only a fraction of your property’s fair market value. The fraction depends on how the property is classified:
- Primary residence (legal domicile): 4% of fair market value
- Commercial property, rental property, or second home: 6% of fair market value
- Agricultural land, non-corporate: 4% of use value
- Agricultural land, corporate-owned: 6% of use value
- Manufacturers and utilities: 10.5% of fair market value
The gap between 4% and 6% is the single biggest driver of tax differences between similar properties. A homeowner living in a $200,000 house has an assessed value of $8,000. A landlord renting out that same house has an assessed value of $12,000 before millage even enters the picture.1The National Agricultural Law Center. South Carolina Code 12-43-220 – Classifications and Assessment Ratios
The 4% rate is not automatic. You or your agent must apply for the legal residence classification before the first penalty date on that year’s tax bill, and the application requires you to certify under penalty of perjury that the home is your legal domicile, that no member of your household claims residency elsewhere, and that you aren’t claiming the 4% ratio on another property. If you move or convert the home to a rental, the 6% ratio kicks in and you’re responsible for telling the county.1The National Agricultural Law Center. South Carolina Code 12-43-220 – Classifications and Assessment Ratios
Millage Rates by District
Once the assessment ratio produces your assessed value, that number is multiplied by the millage rate. One mill equals one dollar of tax per $1,000 of assessed value. Anderson County has dozens of tax districts, each with its own combined rate.2South Carolina Revenue and Fiscal Affairs Office. Property Tax Frequently Asked Questions
For the 2025 tax year, the county’s own levy is 83.70 mills, covering county operations, the library system, capital projects, infrastructure reserves, and general obligation bonds. That’s only part of what shows up on your bill. School district taxes, fire district levies, and any municipal taxes stack on top. Total millage rates run from about 249 mills in some unincorporated areas to more than 419 mills in certain districts inside city limits.3Anderson County South Carolina. Anderson County 2025 Levy Sheet
The Anderson County Auditor publishes a levy sheet each year listing the exact millage for every district. Your tax notice identifies which district your property falls in, and you can also look it up through the county’s online property records before the bill arrives.
Calculating Your Bill
The formula is simple once you have the three inputs. The Anderson County Assessor uses a $50,000 home as an example.
For a primary residence at the 4% ratio with a 295-mill rate: $50,000 × 0.04 = $2,000 assessed value. Then $2,000 × 0.295 = $590. Owner-occupied homes are exempt from school operating taxes, so you subtract the school operating portion: $2,000 × 0.17 = $340. Final bill: $250.4Anderson County South Carolina. Assessor and Real Property
The same $50,000 property without the legal residence classification is assessed at 6%, producing a $3,000 assessed value. At the same 295 mills, the bill comes to $885 with no school tax credit. That’s more than triple the owner-occupied bill on the same house.4Anderson County South Carolina. Assessor and Real Property
Your actual millage will differ from 295. Pull your district’s rate from the county levy sheet and run the same math against your appraised value to get a real estimate.
Exemptions That Lower the Bill
Homestead Exemption
If you’re 65 or older, totally and permanently disabled, or legally blind, the first $50,000 of your home’s fair market value is completely exempt from county, municipal, school, and special assessment property taxes. You must have been a South Carolina resident for at least one year and hold fee simple title or a life estate in the property.5South Carolina Legislature. South Carolina Code 12-37-250 – Homestead Exemption for Taxpayers Sixty-Five and Over or Those Totally and Permanently Disabled or Legally Blind
On a home valued at $150,000, the exemption removes $50,000 from the taxable base, so only $100,000 runs through the assessment ratio and millage. Apply through the Anderson County Auditor’s office.6South Carolina Department of Revenue. Exempt Property
School Operating Tax Exemption (Act 388)
Owner-occupied primary residences are fully exempt from the school operating portion of the property tax, under Act 388, which took effect in 2008 and replaced the lost school revenue with a statewide penny sales tax increase. The exemption is automatic once your property carries the legal residence classification at the 4% ratio; you don’t file a separate application, but you do need the 4% classification in place. In the calculation above, this piece knocked $340 off a $50,000 home. It does not apply to rental properties, second homes, or commercial buildings.4Anderson County South Carolina. Assessor and Real Property
Disabled Veteran Exemption
Veterans with a total, permanent, service-connected disability can claim a full property tax exemption on their home and up to one acre of land, plus up to two private passenger vehicles. The exemption takes effect in the year the disability occurs. Surviving spouses also qualify and can claim the exemption immediately, regardless of whether the veteran had previously applied. Qualifying veterans can apply retroactively for up to two prior years if they paid on time during that period. You’ll need a certificate signed by your county service officer or VA documentation confirming total and permanent disability.7South Carolina Department of Revenue.

Reassessment and the 15% Cap
South Carolina requires countywide reassessments every five years. Between cycles, your assessed value generally stays frozen unless something triggers a change, and when the reassessment does hit, state law caps the increase at 15% over the five-year period, no matter how much actual market value has climbed.8South Carolina Legislature. South Carolina Code 12-37-3140 – Determining Fair Market Value
Two exceptions matter. Additions and improvements are assessed at full market value in the year they first appear on the tax rolls, cap or no cap. And the cap doesn’t apply when an “assessable transfer of interest” occurs, which usually means a sale. When you buy a home in Anderson County, the assessed value resets to what you paid, even if that’s a jump well beyond 15%.8South Carolina Legislature. South Carolina Code 12-37-3140 – Determining Fair Market Value
Buyers get caught off guard here. A seller may have enjoyed years of capped increases and a low bill. Once the sale closes, the county reassesses at market value and the new owner inherits a much higher bill.
Billing Dates and Late Penalties
Anderson County mails real property tax notices on October 1 each year, with payment due in full by January 15 of the following year.9Anderson County South Carolina. Treasurer and Taxable Assets Miss that date and penalties stack up on a fixed schedule:
- After January 15: 3% penalty added
- After February 1: an additional 7% penalty (10% total)
- After March 16: an additional 5% penalty (15% total)
On a $2,000 bill, waiting until mid-March turns it into $2,300. These penalties are not negotiable and not waivable for hardship.10South Carolina Legislature. South Carolina Code Title 12 Chapter 45 – Section 12-45-180 If delinquency continues past the penalty period, the county moves to execution, seizure, and eventually a delinquent tax sale, with a 12-month redemption window at escalating interest.11South Carolina Legislature. South Carolina Code 12-51-90 – Redemption of Real Property Contacting the Treasurer’s office before that stage opens more options than waiting does.
