Property tax in Oconee County, South Carolina

Who sends the property tax bill in Oconee County, and how do you pay it?

The bill comes from the Oconee County Treasurer. The value it is based on is set by a separate office, the Oconee County Assessor, which is who to ask if the value looks wrong. For how to look up and pay the bill, go to the county's own payment information.

Three county offices share the work: the Assessor values real estate and grants the 4% legal residence rate, the Auditor sets the millage, prepares the tax notices and handles the homestead exemption, and the Treasurer collects the taxes. Town taxes for Salem, Seneca, Walhalla, West Union and Westminster are added to the county and school millage on the same bill rather than billed separately, along with fire district taxes. The 4% legal residence rate is not automatic: apply to the Assessor between January 1 and January 15 of the following tax year; once filed it renews automatically unless ownership, address or use changes. Card payments carry a 2.35% fee in the office or online, and e-checks online cost $2.00.

When are property taxes due in Oconee County?

For the 2026 bill, Oconee County has one due date: January 15, 2027. South Carolina law makes property taxes due by January 15 after the bills go out, and the county says each tax year's bill is payable by January 15 of the next year without penalty. Tax notices go out in October or November. January 15, 2027 is a Friday and a regular business day. A mailed payment must be postmarked no later than the due date to avoid penalty, and the county says a due date that falls on a weekend or a county holiday moves to the next business day. Under state law, taxes not paid by January 15 pick up penalties in three steps: 3% on January 16, another 7% on February 2 and another 5% on March 17. If tax notices go out late, the first penalty does not apply until 30 days after the notices are mailed. On March 17 the Treasurer issues a tax execution to the county's Delinquent Tax Office, which mails the first delinquent notice around April 1, adds collection costs, and can sell the property at a tax sale held in October, November or December.

If a conference with the Assessor does not settle it, state law gives you 30 days after the conference to file a written protest. Within 30 days of the Assessor's written response you may appeal to the Board of Assessment Appeals by written notice to the Assessor, and within 30 days of the Board's decision you may request a contested case hearing before the South Carolina Administrative Law Court.
