The Auditor's office calculates millage to satisfy annual budget requirements for Charleston County, including 43 tax districts. In addition, this office calculates, creates and mails tax bills for real estate, mobile homes, motor vehicles, watercraft, aircraft and business-owned personal property.
The Constitution of 1868 gave members of the S.C. General Assembly the authority to create the first office of County Auditor. By state law, each of the 46 counties in South Carolina has an Auditor's Office. Charleston County Auditors are elected to four-year terms in the General Election.
The Auditor's Office is committed to serving all citizens of Charleston County. In an effort to raise awareness of the advantages of being a homeowner and primary resident within the county, our Outreach Division is available for free public consultations. If you would like a member of our team to attend a local community event to provide more information regarding exemptions and discounts contingently applicable to county taxes, please, reach out to us at firstname.lastname@example.org or 843-958-4200 option 9.
