South Carolina Road Reform Bill Draws Tax Increase Charges from Oconee County Official
Why It Matters
A South Carolina road infrastructure bill moving through the General Assembly is drawing sharp criticism from a prominent county official who argues the legislation amounts to a double tax burden on residents — requiring them to pay the existing state gas tax while also authorizing local governments to raise additional taxes to maintain roads transferred from state to county control.
The debate highlights a broader tension between state-level fiscal management and the responsibilities being pushed onto local governments, with real consequences for South Carolina taxpayers and the condition of roads across the state.
What Happened
Matthew Durham, Chairman of Oconee County Council and founder of Oconee County Conservatives, published a commentary on April 29, 2026, arguing that S. 831 — also known as H. 5071 and referred to as the SCDOT Modernization Act — is not road reform but a tax increase dressed in policy language.
The South Carolina General Assembly’s House Ways and Means Committee merged the two versions of the bill on April 1 and advanced it to the House floor. The legislation would transfer state-maintained roads to county governments — roads Durham says the state has neglected for decades despite collecting a gas tax raised specifically in 2017 to maintain them.
Under the bill, the state would retain gas tax revenue while counties would assume maintenance liability. To help cover those costs, the legislation would allow counties to impose a second transportation penny sales tax, doubling the current cap, and permit counties to raise property taxes above the millage cap for expenses tied to the transferred roads.
Durham also raised concerns about a provision under Section 15 of the bill, which would require counties to obtain SCDOT approval for speed limits and weight restrictions on roads they own and fund — leaving the same state bureaucracy that failed to maintain the roads in a position of ongoing operational control.
By the Numbers
Key figures from the legislation and its context:
- The South Carolina gas tax was raised in 2017 specifically to fund maintenance of state roads.
- The bill would allow counties to impose a second transportation penny sales tax, doubling the existing cap.
- A System Realignment Fund is created under the bill but carries no dedicated or guaranteed funding.
- At least four lawmakers — Representatives Micah Caskey, Kevin Hardee, Bill Whitmire, and Adam Duncan — have either voted against the bill in committee or withdrawn their support.
- Two alternative measures, H. 5331 and H. 5362, have been proposed as competing approaches that do not include new taxing authority.
Zoom Out
The dispute in South Carolina reflects a pattern seen in several states where aging infrastructure burdens are shifted from state agencies to county and municipal governments without corresponding funding guarantees. Critics in multiple states have raised concerns that such transfers create unfunded mandates that ultimately fall on local property taxpayers.
South Carolina has faced ongoing scrutiny over how transportation dollars are managed at the state level. A separate debate has emerged over utility cost responsibilities tied to data centers, adding to a wider conversation in the state about who bears the financial weight of public infrastructure — and whether Columbia is exercising adequate fiscal discipline before seeking new revenue.
Durham argues that the state’s problem is not insufficient revenue but insufficient accountability, pointing to continued appropriations for non-essential projects alongside growing gas tax and federal infrastructure receipts. South Carolina recently secured a $63 million tobacco settlement payment, underscoring that the state is not without financial resources.
What’s Next
The bill now awaits action on the House floor, where Durham and other opponents are calling on lawmakers to make substantive changes before any final vote. Durham outlined three specific demands: remove the new county-level taxing authority, require that guaranteed funding follow any road transferred to counties, and make the program genuinely voluntary with enforceable taxpayer protections.
If those changes are not made, Durham urged lawmakers to vote against the measure entirely and begin the process over. Supporters of the bill have argued the state cannot sustain its current road maintenance responsibilities, though opponents contend that argument does not justify authorizing new layers of local taxation without structural accountability reform at the state level.
