How Property Tax Works

Lancaster County, South Carolina operates under a property tax system that funds essential local services including schools, law enforcement, fire protection, roads, and county operations. Property taxes are calculated based on assessed value, which is determined by the County Assessor and reassessed periodically. The county's effective millage rate is 0.5215 mills (0.52%), though the actual tax rate varies by location within the county due to special taxing districts and municipal boundaries.

Property tax rates in Lancaster County can differ significantly depending on your specific location, as various special districts for fire protection, road maintenance, and other services may apply additional millage rates. The county base millage rate is 0.3455 mills, but when combined with school district taxes and any applicable special district assessments, total rates typically range from 0.45% to 0.60% of assessed value. Property owners should verify their specific tax rate based on their exact location and applicable taxing districts.

Section 4

Supplemental Tax Bills

Supplemental property taxes in Lancaster County are additional tax bills issued when there are changes to property ownership, improvements, or new construction that occur after the annual assessment roll is completed. These typically arise when properties are subdivided, new structures are built, or significant improvements are made that increase the assessed value mid-year.

Supplemental taxes are calculated by applying the current tax rate to the difference between the new assessed value and the previous assessed value, prorated for the remaining months in the fiscal year. For example, if a $50,000 home addition is completed in January and increases your assessed value by $50,000, you would receive a supplemental tax bill for approximately $261 (using the base 0.5215% rate) prorated for the remaining portion of the tax year. These bills are typically issued within 60 days of the assessment change and have separate due dates from regular property tax bills.

Escrow & Property Taxes

Most mortgage lenders in Lancaster County require property tax escrow accounts, where monthly tax payments are collected along with your mortgage payment and held until tax bills are due. Lenders typically collect 1/12th of your estimated annual property tax each month, plus an additional cushion amount allowed by federal law. Your lender will pay your property taxes directly to Lancaster County when they become due.

Escrow accounts are analyzed annually, usually around the anniversary of your loan, to ensure adequate funds are collected. If property taxes increase due to reassessment or rate changes, your monthly escrow payment will be adjusted accordingly. Property owners with escrow accounts should still review their tax bills for accuracy, even though the lender handles payment. You can verify that your taxes were paid on time by checking with the Lancaster County Treasurer's office or viewing your account online. If you pay off your mortgage or refinance, remember to make arrangements for direct tax payment to avoid penalties.

Q: When are property taxes due in Lancaster County for FY 2025-2026? A: Property taxes are due January 15 with no penalty. A 3% penalty applies from January 16 through February 1. After February 1, additional penalties accrue. Delinquent taxes must be paid by October 31 to avoid tax sale proceedings.

Q: What is the Legal Residence Credit and how do I apply? A: The Legal Residence Credit exempts the 0.176 mill school operations tax from your primary residence. This is a tax credit, not an exemption, and requires annual application. Contact the County Auditor at 803-285-7424 or email auditor@lancastercountysc.gov if you don't see this credit on your tax bill.

Q: Are there tax credits available for seniors or disabled persons? A: Yes, Lancaster County offers homestead exemptions (which function as assessment caps) for qualifying seniors and disabled persons. These limit annual assessment increases rather than reducing market value. Applications are required and processed by the County Auditor's office.

Q: How often are properties reassessed in Lancaster County? A: South Carolina law requires counties to conduct countywide reassessments every five years, though market adjustments may occur annually. Property owners receive notice of assessment changes and have appeal rights during specified periods.

Q: What are the penalties for late property tax payments? A: A 3% penalty applies from January 16-February 1. Additional penalties and interest accrue monthly after February 1. Properties with taxes delinquent after October 31 may be subject to tax sale proceedings.

Q: Why is my tax rate different from my neighbor's? A: Tax rates vary within Lancaster County based on special taxing districts such as fire districts, road maintenance districts, and municipal boundaries. Your exact location determines which combination of tax rates applies to your property.

Q: How do I appeal my property assessment? A: Assessment appeals must be filed within specified timeframes following reassessment notices. Contact the Lancaster County Assessor's office for appeal procedures, deadlines, and required documentation to challenge your property's assessed value.

Q: Do special districts add to my property tax bill? A: Yes, properties may be subject to additional millage rates for fire protection districts, road maintenance districts, and other special services. These appear as separate line items on your tax bill and vary by location within the county.

Q: What happens if I don't apply for available tax credits? A: Most tax credits in Lancaster County require annual application and are not automatically applied.
