Charleston County, South Carolina property-tax payment and appeal deadlines
Tax bills, payment rules, and valuation-review windows are controlled by the local jurisdiction and the governing state framework. The reviewed record below separates published figures from items that still require confirmation with Charleston County Assessor's Office.
Rate context
ConfirmSouth Carolina property-tax millage varies by county, municipality, school district, and tax district; no single countywide effective rate is published.
Statement mailing
PublishedTypically the first week of October 2026; Charleston County says tax bills are usually mailed in the fall and are generally available by October 1.
Payment deadline
PublishedFor 2026 real-property taxes, payment is due January 15, 2027 without penalty; Charleston County's published penalty schedule adds 3% after January 15, 7% more after February 1, and 5% more plus delinquent handling after March 17.
Valuation protest
PublishedFor 2026, an assessment notice controls and appeal rights generally expire 30 or 90 days after mailing; if no notice is sent, Charleston County allows a written appeal through the last day to pay without penalty, generally January 15, 2027.
Do not assume a grace period.
The reviewed record identifies the payment timing above but does not establish a universal penalty schedule for this page. Late charges, interest, collection costs, tax-sale procedures, and lien or foreclosure timelines can depend on state law and the local collector’s process. If the deadline is close or a balance is delinquent, contact the tax collector directly and request the current payoff amount in writing.
Treat a published payment deadline as a hard operational date and retain your receipt or confirmation number.
From assessment to collection
01Valuation and notice
Review the assessment notice as soon as it arrives. The protest window may run from the notice date rather than from the payment due date.
02Statement and account review
Match the tax statement to the parcel or account number and confirm exemptions, assessed value, taxing units, credits, and balance.
03Payment confirmation
Use the official collector channel, then save the receipt, transaction reference, and date posted. A bank submission is not always the same as a county posting date.
