Taxation and Finance South Carolina 4 Minutes Read ยท published March 08, 2026 Flag of South Carolina

Mount Pleasant, South Carolina requires businesses and certain sellers to follow state and local rules for sales, use, and excise taxes. This guide explains which taxes typically apply in Mount Pleasant, who enforces them, how to register and remit, common compliance risks, and practical steps to contest assessments or obtain exemptions. It covers state-administered sales and use tax, local option taxes that affect transactions in Charleston County, and municipal business licensing or excise measures enforced by Town departments.

Overview of Applicable Taxes

South Carolina sales and use tax is administered by the South Carolina Department of Revenue and applies to retail sales of tangible personal property and certain services; local option and hospitality-type excise taxes may also apply within Mount Pleasant. Businesses should register for state sales tax accounts and check local licensing requirements before opening or expanding operations.

Key distinctions:

  • State sales and use tax - administered by South Carolina DOR.[3]
  • Local option taxes and municipal excise (e.g., accommodations, hospitality) - may apply depending on location within Charleston County and local ordinances.[1]
  • Business license/privilege taxes or permit fees - issued and enforced by Town departments; registration required for most commercial activities.[2]
Start registration early: state and local registrations can have separate timelines and requirements.

Penalties & Enforcement

Enforcement involves state and municipal authorities depending on the tax. The South Carolina Department of Revenue enforces state sales and use tax collection and assessment; Town of Mount Pleasant departments enforce municipal licenses, hospitality taxes, and local ordinances. Where the municipal code sets penalties, the code or department page is the controlling instrument and should be consulted directly.[1]

  • Monetary fines: specific fine amounts for municipal tax or license violations are not specified on the cited municipal code page and must be confirmed with the ordinance or department cited below.[1]
  • State sales tax penalties: the South Carolina DOR publishes civil penalties and interest schedules for late payment and underreporting; consult the DOR for exact percentages and computation methods.[3]
  • Escalation: first, repeat, and continuing offences and escalation steps are governed by the specific ordinance or state statute and are not specified on the cited municipal page where a consolidated schedule is absent.[1]
  • Non-monetary sanctions: orders to cease operations, license suspension or revocation, permit denials, seizure of taxable goods, and referral to court are enforcement options used by municipal or state authorities.
  • Enforcers and complaint pathways: South Carolina DOR handles state sales/use matters; Town of Mount Pleasant Finance/Business License and By-law Enforcement handle municipal licensing and local excise compliance. Official department contact pages provide complaint forms and reporting instructions.[2][3]
  • Appeals and review: appeal routes vary by authority. For DOR assessments, administrative protest procedures and appeal to the Administrative Law Court or Tax Court apply per DOR guidance; time limits are set by statute and DOR rules. For municipal assessments or license decisions, check the ordinance or department for appeal deadlines, which are often short and specified in the controlling instrument or notice (if not specified on the cited page, contact the department directly).[3][1]
If you receive an assessment, note the appeal deadline on the notice and act promptly.
