Property tax rates in Lancaster County, SC are built from three pieces: the fair market value of your property, a state-fixed assessment ratio (4% for an owner-occupied home, 6% for most other real property), and a local millage rate that totals 329.7 mills for the 2025 tax year before any city or fire district levy is added. On a $200,000 legal residence, that math works out to roughly $1,232 a year once the school operating credit is applied. The same property held as a rental would owe about $3,960. Where you live in the county, what the property is used for, and which exemptions you claim decide which end of that range you land on.
How Your Taxable Value Is Set
South Carolina does not tax property on its full market value. Each property type carries an assessment ratio, fixed statewide under SC Code 12-43-220, that Lancaster County has no power to change.1South Carolina Legislature. South Carolina Code 12-43-220 – Classifications Shall Be Equal and Uniform
- Owner-occupied homes (legal residence): 4% of fair market value, covering the home and up to five contiguous acres.
- Other real property, including rentals, second homes, commercial buildings, and vacant land: 6% of fair market value.
- Personal automobiles and light trucks: 6%.
- Manufacturing, utility, and other personal property such as boats and heavy equipment: 10.5%.
- Agricultural land owned by individuals or qualifying small corporations: 4% of agricultural-use value.
The gap between 4% and 6% is bigger than it looks. A $250,000 home assessed at 4% has a taxable value of $10,000. Classified at 6%, that same property has a taxable value of $15,000, a 50% jump before any millage is applied.
2025 Millage Rates in Lancaster County
Millage is stated as dollars of tax per $1,000 of assessed value. One mill equals $1. For the 2025 tax year, the countywide layers stack up like this:2Lancaster County, SC. 2025 Millage Rates
- County Operating: 76.5 mills
- County Debt: 7.2 mills
- Capital Improvement: 5.0 mills
- County subtotal: 88.7 mills
- School Operating: 176.0 mills
- School Debt: 65.0 mills
- School subtotal: 241.0 mills
Those two layers together come to 329.7 mills. If you live inside the City of Lancaster, Town of Kershaw, Heath Springs, or Van Wyck, your bill also carries a municipal millage on top of that. Residents in unincorporated areas skip the municipal layer but may owe fire district millage. The Lancaster County Auditor publishes the full district-by-district chart each year.
How to Calculate Your Property Tax Bill
Once you know the three inputs, the math is direct. Take a home with a fair market value of $200,000, classified as a legal residence, in an area with total applicable millage of about 330 mills:
- Assessed value: $200,000 × 4% = $8,000
- Gross tax: $8,000 × 0.330 = $2,640
- School operating credit: $8,000 × 0.176 = $1,408
- Net tax: $2,640 − $1,408 ≈ $1,232
The school operating credit is the biggest single reduction most homeowners see. Since 2007, South Carolina law has fully exempted owner-occupied legal residences from school operating millage. The 176.0-mill line still appears on your bill, then gets credited back to zero for qualifying properties. School debt (65.0 mills) still applies.
Change nothing except the classification, and the numbers move sharply. That same $200,000 property held as a rental is assessed at 6% ($12,000), the full 330 mills apply with no school operating credit, and the annual bill runs about $3,960.
Claiming the 4% Legal Residence Rate
The 4% ratio is not automatic. You have to file a Legal Residence Special Assessment Application with the Lancaster County Assessor.3Lancaster County, SC. Legal Residence Special Assessment Application The application requires a South Carolina driver’s license showing the property address, an SC vehicle registration showing the same address, and additional documents when the property is held in a trust or LLC. If you still own a previous residence, you need a letter from the prior taxing jurisdiction confirming your exemptions have been removed there.
Incomplete or unsigned applications are not processed. If your application is still pending when the bill arrives, pay at the 6% rate; the county will refund the difference once the 4% classification is approved. And if you later become ineligible, say by moving out or converting the home to a rental, you have to notify the Assessor within six months or face a penalty.
Exemptions That Reduce the Bill Further
Homestead Exemption for Age 65, Disability, or Blindness
If you are 65 or older, totally and permanently disabled, or legally blind, and have been a South Carolina resident for at least one year, the Homestead Exemption removes the first $50,000 of your home’s fair market value from all county, municipal, school, and special assessment taxes.4South 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 You must hold fee simple title or a life estate in the property. Applications go through the Lancaster County Auditor with documentation of age, disability, or blindness.5South Carolina Department of Revenue. Exempt Property On a $200,000 legal residence, the exemption drops the assessed value from $8,000 to $6,000 before millage is calculated.
Disabled Veterans and Surviving Spouses
Veterans with a total, permanent, service-connected disability can exempt their home and up to five contiguous acres, plus up to two privately owned passenger vehicles, from property tax. The exemption takes effect in the year the disability occurs, with no waiting period. Medal of Honor recipients and former prisoners of war from World War I through Vietnam also qualify.6South Carolina Department of Revenue. Veterans – Learn More About SC Property Tax Exemptions A surviving spouse of a disabled veteran can claim the same exemption immediately, even if the veteran never applied during their lifetime.7South Carolina Legislature. South Carolina Code 12-37-610 – Persons Liable for Taxes
Agricultural Use Valuation
Farmland and timberland can be taxed on their agricultural-use value rather than development value. For individuals, partnerships, and qualifying small corporations (no more than ten shareholders, all individuals, no nonresident aliens, one class of stock), the assessment ratio is 4%. Other corporations are assessed at 6%. Timberland tracts must be at least five acres. Non-timber agricultural land must be at least ten acres, though smaller tracts qualify if the owner earned at least $1,000 in gross farm income in three of the five preceding tax years.1South Carolina Legislature. South Carolina Code 12-43-220 – Classifications Shall Be Equal and Uniform The application must be filed before the first penalty date for the year you first claim eligibility. Pulling land out of agricultural use later triggers roll-back taxes covering the difference for previous years.
The 15% Cap on Reassessment Increases
Lancaster County reassesses all real property on a five-year cycle. The most recent reassessment took effect in 2020, following a prior cycle in 2016, with the next scheduled for 2025.8Lancaster County, SC. Frequently Asked Questions – Lancaster County State law caps the increase in fair market value at 15% over any five-year reassessment period.9South Carolina Legislature. South Carolina Code 12-37-3140 – Determining Fair Market Value
Two exceptions matter. New additions or improvements are assessed at full current market value in the year they first become taxable, regardless of the cap. And the cap does not apply when an assessable transfer of interest occurs, most commonly a sale, at which point the property resets to full market value. Minor repairs and reconstruction after a natural disaster do not count as improvements, so those will not trigger a reset. Long-term owners who have not made major changes get the most protection from the cap; recent buyers generally do not.
Appealing Your Assessment
If you think the county overvalued your property, you have 90 days from the mailing date of the assessment notice to file a written objection with the Lancaster County Assessor. You can challenge the fair market value, the special use value, the assessment ratio, or the overall tax assessment.10South Carolina Legislature. South Carolina Code 12-60-2510 If you never received a notice, you can object in writing at any time, though an appeal filed after the first penalty date applies to the following tax year.
The Assessor either corrects the issue or schedules a conference within 30 days. If that does not resolve the dispute, you have 30 days to file a formal written protest describing the property, the facts supporting your position, and the value you believe is correct.11South Carolina Legislature. South Carolina Code 12-60-2520 – Written Request to Assessor Beyond that lies the Lancaster County Board of Assessment Appeals, which meets quarterly.12Lancaster County, SC. Board of Assessment Appeals Appeals that succeed almost always come with comparable sales data rather than a general objection to the value.

Main Street takes only cash, debit or credit cards, cashier’s checks, and money orders.15Lancaster County, SC. Delinquent Tax Collection Unpaid balances eventually lead to a tax sale, with a 12-month redemption window and escalating interest afterward, so it is worth addressing a delinquent bill before it reaches that stage.
