The South Carolina Court of Appeals has ruled in favor of the South Carolina Department of Revenue (SCDOR) in a corporate tax dispute with Tractor Supply Company (TSC). The court's decision, filed on June 17, 2026, confirms that TSC must use combined unitary reporting to calculate its corporate income taxes for the years 2014, 2015, and 2016. This ruling affects TSC's tax obligations and sets a precedent for how multi-state corporations report income in South Carolina.
The case, identified as Appellate Case No. 2024-000013, arose from TSC's challenge to a tax assessment by the SCDOR. The court's ruling is significant as it clarifies the state's approach to corporate income tax reporting, particularly for companies operating in multiple states.
Background
Tractor Supply Company is a retail chain that specializes in farm and ranch supplies. The company generates 99% of its revenue from its retail operations. In 2001, TSC restructured its business, creating two subsidiaries: Tractor Supply Company of Michigan, LLC, and Tractor Supply Company of Texas, LP. This restructuring was partially aimed at reducing TSC's state tax burden.
The South Carolina Department of Revenue conducted audits of TSC in 2006 and 2010. Following the 2010 audit, the Department required TSC to file a combined unitary return for the tax year 2012. However, TSC reverted to separate entity reporting in subsequent years. In 2018, another audit led the Department to conclude that TSC operated within a unitary group and that its previous reporting did not accurately reflect its business activities in South Carolina.
The Department issued a determination stating that TSC owed an additional $1,383,064 in taxes plus interest for the audit period. TSC contested this determination, arguing that the Department had not proven that its separate entity reporting was inaccurate. The case was then brought before the Administrative Law Court (ALC), which ruled in favor of the Department.
The Ruling
The Court of Appeals affirmed the ALC's decision, stating that TSC's use of separate entity reporting did not fairly represent its business activities in South Carolina. The court noted, "the Department proved that TSC's business activity was not fairly represented by utilizing the standard apportionment formula with separate reporting." The ruling was delivered by Judge Curtis.
The court found substantial evidence supporting the Department's claim that TSC had used intercompany transactions to shift income from South Carolina to its subsidiaries, thereby avoiding state taxes. The ALC had previously determined that TSC's reporting practices were misleading and that the Department's requirement for combined unitary reporting was a reasonable alternative method of apportionment.
Impact
This ruling has significant implications for multi-state corporations operating in South Carolina. It reinforces the Department's authority to require combined unitary reporting when separate entity reporting does not accurately reflect a company's business activities. The decision may lead other corporations to reassess their tax reporting strategies, particularly those that utilize similar intercompany transactions to minimize tax liabilities.
The ruling also sets a precedent for how the state interprets its apportionment statutes, potentially influencing future tax assessments and disputes involving corporate entities. It emphasizes the importance of accurately representing business activities in tax reporting and the state's commitment to ensuring fair taxation.
What's Next
Tractor Supply Company may consider appealing the ruling to a higher court, although details on any potential appeal were not available in the court filing. The outcome of this case could influence similar disputes involving other corporations and their tax reporting practices in South Carolina.
