Annexation Tax Comparison Calculator

The Tax Comparison Calculator will calculate the difference between your current Charleston County tax bill and what your tax bill would be if annexed into the Town of Mount Pleasant. The taxes and fees levied against unincorporated parcels are reflected in the first column for Charleston County. The taxes and fees levied against parcels annexed into the town are reflected in the second column for Town of Mount Pleasant.

Please have a copy of your current tax bill, or go to the Charleston County Tax Assessor's website to find the required information needed. If you need help using the calculator or the Charleston County Tax Assessor's website, please contact the Charleston County Auditor's office at (843)958-4200.
