How Property Tax Works

Allendale County, South Carolina operates under the state's property tax system, which serves as the primary funding mechanism for essential local services including education, public safety, infrastructure maintenance, and county operations. The county follows South Carolina's assessment practices where real property is assessed at 4% of fair market value for owner-occupied residential properties and 6% for other real property classifications.

Property tax rates in Allendale County vary by location within the county due to special taxing districts, municipal boundaries, and school district variations. The effective tax rate typically ranges around 2.95% of assessed value for most residential properties, though this can vary based on your specific location and applicable special assessments. Notably, Allendale County has reimposed a 1% Capital Projects Tax effective May 1, 2025, which impacts the overall tax burden for property owners throughout the county.

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.
Section 4

Supplemental Tax Bills

Supplemental taxes in Allendale County are triggered by changes in property ownership, new construction, or significant improvements that increase a property's assessed value during the tax year. When these events occur, the county assessor certifies the new assessment to the county auditor, who computes the additional tax owed and forwards it to the county treasurer for billing.

For example, if you purchase a home in Allendale County mid-year and the new assessment differs from the prior owner's assessment, you may receive a supplemental tax bill for the difference. Similarly, if you complete a major renovation or addition, the increased assessed value will generate a supplemental tax bill for the remaining portion of the tax year. These supplemental taxes are calculated on a pro-rated basis from the date the change became effective through the end of the current tax year.

Escrow & Property Taxes

Most mortgage lenders in Allendale County require property tax escrow accounts for loans with less than 20% down payment. Your lender collects monthly tax payments along with principal and interest, holding these funds in escrow until tax bills are due. The lender typically pays your property taxes directly to the Allendale County Treasurer when due.

Escrow accounts are analyzed annually, and your monthly payment may be adjusted based on actual tax bills and account balance. If your property taxes increase due to reassessment or rate changes, your monthly escrow payment will likely increase. You should receive an escrow analysis statement showing the calculation and any changes to your monthly payment. Property owners can request to pay taxes directly if they meet certain loan-to-value requirements, though this varies by lender policy.
