Illinois courts are now permitting substance-over-form arguments to prevail in state tax disputes. This is important for many taxpayers, both individuals and corporations, not just multinational organizations.
The recent Fourth District decision in PepsiCo, Inc. v. Illinois Department of Revenue offers a useful look at the economic substance doctrine in the Illinois tax context. Not only will the Illinois Department of Revenue disregard corporate form when it concludes a transaction lacks economic substance, courts are willing to permit it.
If you think this case is not new, that’s because it’s not entirely. The same issue was decided last year by the First District Appellate Court. The Fourth District case was paid under the Protest Monies Act and worked its way through the Sangamon County (Springfield) Court system. The First District case went through the Illinois Independent Tax Tribunal, which was then appealed directly to the Appellate Court.
The dispute arose in the combined reporting context and involved Illinois’s “80/20” rule, which allows certain affiliates with predominantly foreign activity to be excluded from an Illinois combined group. PepsiCo argued that one affiliate qualified for the exclusion based on the location of its payroll. The Department of Revenue disagreed, focusing on the role of an affiliated entity that administered expatriate payroll within the corporate group. According to the Department, that entity functioned largely as a conduit rather than an operating business component. If that intermediary were disregarded, the payroll calculation changed and the affiliate no longer qualified for the 80/20 exclusion.
The Fourth District accepted that reasoning. The court examined the operational reality of the entity and concluded its role was largely formal. The entity did not appear to perform meaningful management functions, bear significant risk, or operate with the characteristics typically associated with an independent business activity. In that setting, the court agreed that the Department could look past the intermediary when determining the appropriate tax treatment.
The Fourth District’s decision also sits alongside the earlier First District decision involving the same structure but different tax years. Although the outcomes are consistent, the cases reached the appellate courts through different procedural paths and emphasize slightly different aspects of the analysis.
The First District case involved tax years 2011 through 2013 and arose through the Illinois Independent Tax Tribunal. The Tribunal granted summary judgment in favor of the Department, and the appellate court affirmed. The First District focused primarily on whether PepsiCo Global Mobility (PGM) was actually the employer of the expatriate employees whose payroll PepsiCo attributed to FLNA. Applying common law employment principles, the court concluded that it was the foreign host companies, and not PGN, that controlled the expatriates’ work, supervised them, and bore the economic costs of their employment. Because PGM lacked meaningful control over the employees’ work, the expatriates’ compensation could not be treated as foreign payroll attributable to FLNA.
The Fourth District case involved later tax years (2016 and 2017) and followed a different procedural route. PepsiCo paid the disputed tax under protest and filed suit in Sangamon County. After a bench trial, the circuit court ruled for the Department, and the Fourth District affirmed. While the Fourth District also addressed the employment issue, its analysis placed greater emphasis on the economic substance of PGM itself. The court concluded that PGM functioned largely as a shell entity that existed “on paper” and served primarily as a conduit for expatriate payroll expenses. Because the entity lacked meaningful operational activity and did not function as a genuine economic participant in the underlying business activity, the Department could disregard it when determining FLNA’s 80/20 status.
Despite these differences in emphasis, the two decisions ultimately converge on the same point. Both courts were willing to look beyond the formal corporate structure and examine how the arrangement actually operated in practice. In each case, that inquiry led to the same conclusion: the payroll attributed to PGM could not be used to transform FLNA into an 80/20 company for Illinois tax purposes.
Although the case involves a multinational corporate group, the underlying principle is not limited to large corporations. Many Illinois taxpayers rely on multi-entity structures for legitimate reasons. Closely held businesses commonly separate operating companies from real estate entities. Nonprofits and religious organizations frequently use affiliated entities to carry out specific activities or manage particular assets. Local governments and related organizations often operate through multiple legal entities for governance or liability reasons. And even involving taxpayers without multiple entities, the old adage “don’t let the tax tail wag the dog” still rings true. To better protect on audit, it’s key to have non-business reasons for a structure of decisions.
Although the case involves a multinational corporate group and a combined reporting dispute, the underlying doctrine is not limited to that setting. The economic substance doctrine reflects a broader principle that runs throughout tax law. Courts will not treat the formal structure of a transaction as controlling if the transaction does not reflect meaningful economic activity.
Taxpayers are generally free to arrange their affairs to minimize taxes. But that freedom has limits. When a transaction produces a tax result that is disconnected from the underlying economic reality; that is, when the form of the arrangement does not correspond to what actually occurred, then courts are willing to look past the structure and evaluate the substance of the transaction.
The PepsiCo decisions illustrate how that analysis works in practice. The courts did not simply accept the labels attached to the relevant entities or agreements. Instead, they examined how the arrangement functioned in reality: who exercised control, who bore the economic burden of the activity, and whether the structure had independent significance apart from the tax result it produced.
Those questions are not unique to the combined reporting context. They arise whenever a tax result depends on the formal characterization of a transaction or relationship. When the form of the arrangement does not align with its economic reality, courts may disregard the structure entirely (and these principles may even apply too to the principles of piercing the corporate veil).
The PepsiCo decisions should serve as a reminder of a familiar but sometimes overlooked point. Tax planning can influence how transactions are structured, but the tax result must ultimately reflect the underlying economic substance of the arrangement. When the tax objective becomes the primary driver of the structure, courts may conclude that the transaction lacks independent economic significance.
