Charleston County Tax Estimator

Primary Residence

The tax rate for a primary home in Charleston County is 4% of its assessed value, multiplied by a fractional millage rate (usually around 0.25), with eligible tax credits and tax relief. See the example provided by the Auditor’s Office, where the annual tax on the average $200,000 home is just over $1,000.

Second Home or Investment Property

The tax rate for a secondary home in Charleston County is 6% of its assessed value, again multiplied by a fractional millage rate. Even though secondary properties are not eligible for tax credits, the rate is still very friendly for those looking for a vacation home or investment property.

Homestead Exemption

The S.C. Homestead Exemption Program is for homeowners over age 65, or disabled, or legally blind, allowing a tax exemption of up to $50,000 of the value of the home. The exemption is for S.C. legal residents, and only for the primary residence.
