How Mount Pleasant Property Taxes Work
Mount Pleasant is a town within Charleston County. All property tax administration flows through Charleston County offices.

The County Auditor then applies the correct assessment ratio to calculate the taxable value and generates the bill. The County Treasurer collects the payment.

Properties just outside town limits pay only county and school district rates.

Mount Pleasant Assessment Ratios and the Legal Residence Application
South Carolina sets assessment ratios at the state level. Under S.C. Code Ann. Title 12, Chapter 43, owner-occupied primary residences in Mount Pleasant are assessed at 4% of fair market value. Investment properties, second homes, rental units, and commercial parcels are assessed at 6%. Manufacturing properties carry a 10.5% ratio.
The gap between 4% and 6% is especially significant in Mount Pleasant, where property values are higher than the state average. On a home worth $600,000, the taxable value at 4% is $24,000. At 6%, it rises to $36,000. Applied against the combined town-county-school millage rate, this difference can mean over $1,000 per year.
To qualify for the 4% owner-occupied rate, a Mount Pleasant homeowner must file a Legal Residence Assessment Application with the Charleston County Assessor. This filing is not automatic after purchase. New homeowners should submit the application as soon as possible after closing to avoid being assessed at the higher 6% rate while the paperwork is processed. The Assessor will confirm eligibility and update the parcel's records once the application is approved.
Chapter 43 also requires Charleston County to conduct a countywide reassessment every five years. Given Mount Pleasant's fast-growing real estate market, reassessment years can produce noticeable changes in assessed values across town.
Mount Pleasant Property Tax Due Dates and Penalties
Mount Pleasant property taxes are due January 15 of each year. S.C. Code Ann. Title 12, Chapter 45 establishes both the due date and the penalty structure for late payments statewide.
Missing the January 15 deadline adds a 3% penalty. A second penalty of 7% follows at a later threshold. A third penalty of 5% then applies on top of the accumulated balance. For Mount Pleasant property owners with high assessed values, these cumulative penalties can amount to a substantial dollar figure.
Delinquent accounts are governed by S.C. Code Ann. Title 12, Chapter 51. A formal delinquency notice issues on April 1 for accounts that missed January 15. The property owner then has a 12-month redemption window to pay the full balance plus all accrued fees. Acting within the redemption period avoids further escalation of the delinquency process.
Homestead Exemption for Mount Pleasant Seniors and Disabled Owners
Qualifying Mount Pleasant residents can apply for the South Carolina Homestead Exemption. Under S.C. Code Ann. Title 12, Chapter 37, the exemption removes the first $50,000 of fair market value from taxation. Eligible owners must be 65 or older, totally and permanently disabled, or legally blind, and must have been South Carolina residents for at least one full calendar year.
Senior residents who have lived in South Carolina for at least one year and who are 65 or older qualify for the Homestead Exemption on their primary home in Mount Pleasant. The exemption is applied by the Charleston County Auditor's office. Applications must be submitted directly to the Auditor, not the Assessor or the town.
In a high-value market like Mount Pleasant, where the median home price is significantly above the state average, the $50,000 exemption may represent a modest portion of overall value. However, the tax savings are still meaningful, particularly for long-term residents on fixed incomes. The South Carolina Association of Counties at sccounties.org offers additional information on the Homestead Exemption process for all South Carolina counties.
Appealing Mount Pleasant Property Tax Assessments
If you believe the Charleston County Assessor has overvalued your Mount Pleasant property, you have the right to file an appeal. The appeal starts with a written objection to the Assessor submitted within 90 days of receiving the assessment notice. Providing a recent independent appraisal or a list of comparable sales in Mount Pleasant strengthens any objection.
Unresolved disputes can proceed to the Charleston County Board of Assessment Appeals. A final escalation path leads to the South Carolina Administrative Law Court. S.C. Code Ann. Title 12, Chapter 60 establishes the formal framework for these appeals throughout the state. Each step of the appeal requires timely action, so property owners should track deadlines carefully once they file an initial objection.
Investment property owners in Mount Pleasant who are assessed at 6% sometimes appeal on the basis that their property qualifies for a lower ratio. These cases require documentation showing primary occupancy. The Assessor reviews all supporting materials before issuing a determination.
Note: Appeals do not pause the obligation to pay taxes. Property owners should pay their bill on time even while an appeal is pending to avoid late penalties. If the appeal succeeds, an adjustment or refund will follow.
