How Property Tax Works

Berkeley County's property tax system is the primary funding mechanism for essential local services including schools, public safety, infrastructure, and county operations. Property taxes are levied on the assessed value of real estate, which is determined by the Berkeley County Assessor's Office and reassessed periodically to reflect current market conditions.

The effective property tax rate in Berkeley County varies by location within the county due to special taxing districts such as school districts, fire districts, and municipal service areas. The combined millage rate typically ranges from 70-75 mills (7.0%-7.5%) applied to the assessed value, which is generally set at a percentage of fair market value. Property owners should note that their actual tax rate depends on their specific location and the combination of taxing districts that serve their property.

All property tax credits and exemptions require formal application and are not automatically applied to your tax bill. Property owners are responsible for understanding and applying for any credits they may be eligible to receive.

When Are Property Taxes Due?

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 are additional property tax bills issued when there is a significant change in a property's assessed value during the tax year. According to SC Code §§12-60-2510 and 12-60-2520, supplemental taxes are triggered when the county assessor records an increase in a property's fair market value by $1,000 or more due to new construction, improvements, or ownership changes that reveal higher market value.

The supplemental tax is calculated by applying the current tax rate to the difference between the new assessed value and the previous assessed value, prorated for the portion of the tax year remaining. For example, if a $500,000 home receives a $100,000 improvement completed in January, and the assessed value increases by $40,000 (at 40% assessment ratio), the supplemental tax would be approximately $2,800-3,000 (using 70-75 mill rate) for the full year, prorated from the completion date.

Section 5

Escrow & Property Taxes

Most mortgage lenders require property tax escrow accounts for borrowers with less than 20% down payment or those who choose this option for convenience. Your lender collects a portion of your estimated annual property tax bill with each monthly mortgage payment and holds these funds in an escrow account. The lender then pays your property taxes directly to Berkeley County when they become due.

Lenders must provide annual escrow statements showing deposits, payments, and account balances. If your property taxes increase due to rate changes or reassessment, your lender will adjust your monthly escrow payment accordingly. Property owners should verify that their lender has paid taxes correctly and on time, as the property owner remains ultimately responsible for tax obligations even when using escrow services.

Q: What tax credits are available and how do I apply? A: The Homestead Exemption provides up to $50,000 reduction in assessed value for qualifying primary residences. The School Tax Credit (4% Special Assessment Credit) provides additional savings. Both require formal application - homestead applications are ongoing, while the 4% credit application deadline is January 15, 2026.

Q: How does the Homestead Credit work? A: The Homestead Credit doesn't reduce your market value but exempts the first $50,000 of assessed value from taxation. It also caps annual assessment increases for qualified homeowners. You must apply through the Berkeley County Assessor's Office and requalify if ownership changes.

Q: How do I appeal my property assessment? A: Assessment appeals must be filed by July 31, 2025 (90 days from notice date). Contact the Berkeley County Assessor's Office for appeal forms and procedures.

Q: What are the penalties for late payment? A: Late payment penalties and interest charges apply after the due date. Contact Berkeley County Treasurer's Office for current penalty rates and payment grace periods.

Q: Can I pay property taxes online? A: Yes, Berkeley County typically offers online payment options. Visit the Berkeley County website or contact the Treasurer's Office for available electronic payment methods.

Q: Why did my tax bill increase if rates didn't change? A: Tax bills can increase due to property reassessment, new construction, loss of credits/exemptions, or changes in special district assessments even when base rates remain constant.

Q: What special district taxes might apply to my property? A: Depending on location, you may pay additional taxes for fire protection districts, library districts, municipal services, or special assessment districts. Your specific combination depends on your property's location within Berkeley County.
