How Property Tax Works

Darlington County, South Carolina operates on a property tax system that serves as the primary funding mechanism for essential local services including education, public safety, infrastructure maintenance, and county operations. Property taxes in Darlington County are assessed annually based on the fair market value of real estate and personal property, with assessments conducted by the County Assessor's Office.

The effective property tax rate in Darlington County varies significantly based on your specific location within the county due to multiple overlapping taxing jurisdictions and special districts. For the 2025 tax year, the combined millage rate is approximately 2.95 mills (0.295%) for properties within Darlington City and Denmark City limits, though rates differ across various special taxing districts throughout the county. Property owners should expect their actual rate to vary based on school district boundaries, fire districts, and other special assessments that apply to their specific property location.

Supplemental Tax Bills

Supplemental property taxes in Darlington County are triggered when there are changes in property ownership, completion of new construction, or significant improvements that increase a property's assessed value mid-tax year. These supplemental assessments ensure that property taxes reflect current ownership and property conditions rather than waiting for the next regular assessment cycle.

When a supplemental tax is issued, it covers the difference between the previous assessment and the new assessment, prorated for the remaining months in the tax year. For example, if a $400,000 home sells in January and the new assessment increases the value to $450,000, the new owner would receive a supplemental tax bill for the additional $50,000 in assessed value, calculated at the applicable millage rate and prorated for the remaining 11 months of the tax year.

Escrow & Property Taxes

Most mortgage lenders in Darlington County require property tax escrow accounts for loans with less than 20% down payment. Your lender collects monthly escrow payments along with your mortgage payment, depositing these funds into a separate account to pay your annual property tax bill when due. Lenders typically collect 1/12th of your estimated annual property tax bill each month, plus a small cushion to account for potential tax increases.

Property tax payments in Darlington County are typically due by January 15th of each year for the previous tax year. Your mortgage servicer will receive the tax bill directly from the county and make payment on your behalf from your escrow account. If you pay taxes independently, you'll receive your tax bill directly from the Darlington County Treasurer's Office. It's important to verify that your lender has paid your taxes on time, as you remain ultimately responsible for ensuring payment even when using escrow services.
