How Property Tax Works

Colleton County, South Carolina operates under a property tax system that funds essential local services including schools, law enforcement, fire protection, and infrastructure maintenance. Property taxes are the primary source of revenue for county operations and the Colleton County School District. The county follows South Carolina's assessment methodology where residential properties are assessed at 4% of fair market value for owner-occupied homes, while other property types have different assessment ratios.

For the 2025 tax year, Colleton County's property tax rate is 2.95%, representing an increase of 0.56% from 2024. However, your actual effective tax rate may vary depending on your location within the county due to special taxing districts such as fire districts, water/sewer districts, and municipal boundaries. Property owners should verify their specific tax rate by checking which special districts apply to their property, as these additional assessments can impact the total tax burden.

Supplemental Tax Bills

Supplemental taxes are additional property tax bills issued when there are changes in property ownership, new construction completion, or other taxable improvements during the tax year. In Colleton County, supplemental taxes are calculated based on the difference between the previous assessment and the new assessment, prorated for the remaining months in the tax year.

Common triggers for supplemental taxes include: purchasing a home that triggers a reassessment, completing new construction or major renovations, adding structures like pools or detached garages, or removing exemptions due to change in use. For example, if you complete a $100,000 home addition in January and the county assesses it in March, you would receive a supplemental tax bill for the remaining 10 months of the tax year. The supplemental amount would be calculated as: ($100,000 × 4% assessment ratio × 2.95% tax rate) ÷ 12 months × 10 remaining months = $98.33 supplemental tax due.

Escrow & Property Taxes

Most mortgage lenders in Colleton County require property tax escrow accounts for loans with less than 20% down payment. Your lender collects 1/12th of your estimated annual property tax bill with each monthly mortgage payment, depositing these funds into an escrow account. The lender pays your property taxes directly to Colleton County when they become due on April 30th each year.

Lenders typically conduct an annual escrow analysis to ensure adequate funds are collected. If your property taxes increase due to reassessment or rate changes, your monthly escrow payment may be adjusted accordingly. Property owners should review their annual escrow statements and verify that tax payments were made correctly. If you pay off your mortgage or refinance, you become responsible for making direct tax payments to the county. You can verify your current tax status and payment history through the Colleton County Tax Collector's office or their online portal.

Q: When are property taxes due in Colleton County? A: Property taxes for FY 2025-2026 are due by April 30, 2025. Payments received after this date are subject to penalties and interest charges.

Q: What tax credits are available and do they require application? A: The primary credit is the Homestead Exemption providing $50,000 in fair market value exemption ($2,000 reduction in assessed value) for owner-occupied primary residences. This credit requires annual application and approval by the County Assessor's Office. Additional credits may be available for disabled veterans, elderly citizens, and totally disabled individuals, all requiring separate applications.

Q: How does the Homestead Exemption work? A: The Homestead Exemption reduces your home's fair market value by $50,000 for tax calculation purposes (saving approximately $59 annually at current rates). This is NOT an assessment cap - it's a fixed dollar reduction. You must apply through the County Assessor's Office and requalify annually if your ownership or occupancy status changes.

Q: When are properties reassessed in Colleton County? A: South Carolina requires countywide reassessments every five years. Colleton County also conducts annual reviews for properties with ownership changes, new construction, or significant improvements. Property owners can appeal assessments within 90 days of receiving their tax notice.

Q: Can I pay property taxes online? A: Yes, Colleton County offers online payment options through their official website. Payments can be made by bank transfer or credit card, though convenience fees may apply for card payments.

Q: How do special district taxes affect my bill? A: Special districts for fire protection, water/sewer, or other services add additional millage to your base county rate. These vary by location within the county and can add 0.15% to 0.45% to your effective tax rate. Contact the Assessor's Office to determine which districts apply to your property.

Q: What documentation do I need for the Homestead Exemption? A: You need proof of ownership (recorded deed), evidence of primary residence occupancy, and completion of the 4% special assessment ratio application.
