In 2025, property taxes in Mount Pleasant, South Carolina, are based on assessed property values determined by the Charleston County Assessor’s Office. The assessed value is typically lower than the market value, which helps moderate tax bills despite rising real estate prices. Mount Pleasant has a median property tax rate around 0.38%, resulting in a median tax bill of about $2,001 annually. Homeowners’ tax bills vary widely depending on neighborhood, property size, and improvements, with the 25th percentile around $1,384 and the 75th percentile near $3,178. Tax bills in some high-value areas can reach over $5,000.
2025 is also a reassessment year for Charleston County, impacting Mount Pleasant. Properties are reassessed every five years to reflect the current market value, which has risen significantly in recent years, with some areas seeing property values increase by 71% or more since the last reassessment. However, a 15% cap on tax increase limits dramatic tax hikes for homeowners for this reassessment cycle. If homeowners believe their property assessment is incorrect, they can file objections with the Assessor’s Office to dispute the valuation.
The town of Mount Pleasant recommends a millage rate of 43.3 mills for FY 2025, which is a factor in calculating the final tax bill. Various exemptions and credits may also apply to reduce tax liabilities, including homestead exemptions and sales tax credits.
