Mount Pleasant, South Carolina Sales Tax Rate

An affluent suburban town across the Cooper River from Charleston, connected by the iconic Arthur Ravenel Jr. Bridge (one of the longest cable-stayed bridges in the Western Hemisphere). One of the fastest-growing municipalities in South Carolina. The economy is a mix of retail (Mount Pleasant Towne Centre, shopping centers), healthcare (East Cooper Medical Center), and professional services. Many residents commute to Charleston. Shem Creek is a famous waterfront dining and shrimping destination. Boone Hall Plantation is one of the most-visited historic plantations in the area.

The combined sales tax rate in Mount Pleasant is 9.000%, composed of the South Carolina state rate of 6.000% plus a local portion of 3.000%.

The formula to calculate sales tax for any purchase:

For a $150.00 purchase in Mount Pleasant: tax is $13.50 ($150.00 × 0.09000), total is $163.50.

Visitor spending around Arthur Ravenel Jr. Bridge and Shem Creek flows straight through the 9.000% combined rate — on dining, retail, entertainment, and ground transportation alike. For Mount Pleasant operators, that makes visitor volume a direct driver of sales tax remittance, and it makes getting the rate right on every channel (POS, online booking, mobile ordering) a compliance issue, not a rounding detail.

A room night in Mount Pleasant usually carries more than the 9.000% combined sales tax: most South Carolina lodging markets layer a separate occupancy or lodging tax on top. The exact stack is set locally — confirm the current schedule with Charleston County before publishing rates.

Three charges typically sit on top of the 9.000%: an occupancy tax on the room, a short-term-rental tax that many cities now make the platform collect rather than the host, and any convention-centre or tourism-district assessment covering Arthur Ravenel Jr. Bridge. None of the three is set by South Carolina — which is why a rate that is correct in Mount Pleasant can be wrong one town over. How each is levied and who remits it is worked through in the short-term rental and lodging tax guide rather than restated here.

Admissions taxability is one of the sharpest state-by-state splits: many states tax tickets at the full combined rate — which in Mount Pleasant means 9.000% on top of face value — while others do not tax admissions at all. Before pricing tickets to Arthur Ravenel Jr. Bridge, verify South Carolina's admissions rules.

• Ticket taxability depends on South Carolina's admissions rules — never assume the general rate applies
• Bundled packages (ticket + meal + merchandise) may require allocation
• Non-profit venues may qualify for exemptions — verify with Charleston County

Business events in Mount Pleasant cluster around Boone Hall Plantation, and the spend they generate is squarely taxable. What visiting teams and their finance departments should expect:

• Food, beverage and AV hire billed by the venue carry the full 9.000%, so a five-figure catering line arrives with $900 of tax on every $10,000 of it.
• Booth and exhibit materials shipped in tax-free from another state do not escape — they land as South Carolina use tax at the same rate, self-assessed by whoever brought them in.
• Per diems and receipts diverge here: a meal per diem is not a taxable supply, but an actual restaurant receipt from Mount Pleasant already includes the tax, and expensing both ways in one trip is how the reconciliation breaks.

Retailers working the visitor trade near Arthur Ravenel Jr. Bridge and Shem Creek should implement:

The one that actually bites is address-level rate verification. A visitor-trade business sits close to a municipal boundary far more often than a suburban one does, and Mount Pleasant's 9.000% stops applying at a line that is not always visible from the street — the address-level rate guide covers how to resolve it. Everything else here is configuration: tourism-district surcharges set in the POS, and receipts that show the state and local components separately so a visitor claiming a refund can read what they paid.

Mount Pleasant shoppers and businesses routinely cross into Charleston, North Charleston, Isle of Palms and beyond — and in South Carolina, the combined rate can change at those lines. The tracked neighbors — Charleston, North Charleston — currently share Mount Pleasant's 9.000% combined rate, so the delivery address matters less for rate than for sourcing documentation here.

• Charleston (adjacent W across bridge): combined rate 9.000% — see the Charleston page
• North Charleston (12 mi NW): combined rate 9.000% — see the North Charleston page
• Isle of Palms (5 mi E): outside our tracked South Carolina city set — verify its current combined rate before invoicing deliveries there
• Sullivan's Island (3 mi SE): outside our tracked South Carolina city set — verify its current combined rate before invoicing deliveries there
• Georgetown (30 mi NE): outside our tracked South Carolina city set — verify its current combined rate before invoicing deliveries there

Deliveries are taxed by the destination rules South Carolina applies, not by where the store sits — when an order ships across one of these city lines, re-check the rate for the exact address.

Since South Dakota v. Wayfair, a seller with no premises, staff or stock anywhere near Mount Pleasant can still be required to register in South Carolina and charge 9.000% on what it ships here — presence stopped being the trigger and volume took over. The thresholds that decide it are in the table below; what they do not tell you is that crossing them obliges you to collect at the buyer's local rate, not a state average, which is why Mount Pleasant and its neighbours have to be priced separately. The registration mechanics and the trailing-twelve-month counting rules are in the economic nexus guide.

Audit & Compliance Warning: Because combined tax rates combine state and local tax components, calculating tax based purely on ZIP codes can lead to errors. Many ZIP codes span multiple municipal boundaries with differing rates. For precise auditing, always use address-level geo-lookup.
