Charleston County Advances $4.25 Billion Sales Tax Proposal for November Ballot

CHARLESTON, S.C. — Under new leadership, the Charleston County Council is moving forward with a proposal to place a 25-year, half-cent transportation sales tax on the November 2026 ballot, an initiative projected to raise $4.25 billion for infrastructure, public transit, and land preservation projects. The effort is being spearheaded by County Council Chairman Joe Boykin, who was elected to the leadership post in a 5-4 party-line vote on January 6. Boykin has made the passage of the sales tax referendum his top priority, aiming to succeed where a similar effort failed in 2024. For small and mid-sized companies in Charleston County, the proposed half-cent sales tax presents a classic trade-off. On one hand, improved infrastructure directly addresses major operational headaches like supply chain delays and employee commute times. On the other, any sales tax increase can impact consumer behavior and adds a layer of complexity to financial reporting. The proposed tax is a renewal of an existing half-cent levy first approved by voters in 2004, which is set to expire. The South Carolina General Assembly allows counties to use this funding mechanism for transportation and land conservation. According to a draft proposal advanced by the council, the estimated $4.25 billion in revenue would be allocated among three primary categories: road and infrastructure projects, public transit, and the Greenbelt program for land preservation. Boykin has emphasized a more inclusive and transparent process this time around, citing a significant increase in public engagement. “Between the 2024 engagement and what we have so far in 2026, we’ve already more than doubled the number of folks that have engaged us on this sales tax, which is extremely encouraging and exciting,” Boykin said in March. He stated that this feedback from residents, municipalities, and other stakeholders was used to shape the draft proposal and prioritize projects. This is precisely the kind of local fiscal development where proactive financial management becomes critical for businesses. Companies must ensure their point-of-sale and accounting systems are correctly configured to handle the tax if it passes, avoiding costly errors. In our experience, navigating the patchwork of state and local tax obligations is a significant challenge for many businesses. Our tax preparation and compliance services are designed to help clients manage these complexities, ensuring they remain compliant without diverting focus from their core operations. A significant development in the current proposal is the inclusion of the Charleston Battery Extension project, a major seawall initiative aimed at mitigating chronic flooding on the peninsula. The project, which Cogswell has called one of the city's highest priorities, is slated to receive $225 million from the sales tax revenue. Its eligibility was confirmed by an April 9 opinion from the South Carolina Attorney General’s office, which concluded that flood control is an “integral part of transportation operation” and thus a valid use of the funds. This ruling removed a key uncertainty that had previously clouded the project's funding prospects. The need for such infrastructure is underscored by data showing that about 70 percent of the city’s major tidal flooding events have occurred in the last 10 years, with projections showing these events could triple over the next 25 years. The economic impact is direct, with key thoroughfares like Lockwood Drive and East Bay Street having been closed over 1,200 times in the past five years due to flooding. Business and real estate groups, including the Charleston Trident Association of Realtors (CTAR), have been actively involved in supporting the referendum's passage. The group noted that the tax renewal is essential for funding congestion mitigation, roadway improvements, and the infrastructure necessary to sustain economic growth in the region. Both neighboring Dorchester and Berkeley counties successfully reauthorized their own transportation sales taxes in 2024. Ultimately, business owners should view this not just as a tax issue, but as a strategic one. The long-term economic health of the county, fueled by these infrastructure projects, could create significant growth opportunities. Companies that plan for both the immediate compliance burden and the future benefits will be best positioned to thrive.

With the draft allocations and a preliminary project list now public, the county council will continue to gather feedback before finalizing the referendum language. The council must formally vote to place the measure on the ballot for voters to decide its fate in the November general election.
