Rule of Law:
A foreign tax is creditable under U.S. tax law if its predominant character, determined by its economic substance rather than its form or the foreign government's label, is that of an income tax in the U.S. sense. A tax on actual profits above a defined threshold qualifies as a creditable excess profits tax, even if presented in a formula as a tax on the difference between an actual value and a fictitious, retrospectively calculated value.
Facts:
- During the 1980s and 1990s, the United Kingdom government privatized numerous state-owned companies, including South Western Electricity plc.
- PPL Corporation, a U.S. company, owned a 25% interest in South Western Electricity.
- Many of the newly privatized companies were subject to rate regulations for an initial period, typically four years, during which they increased profits primarily through efficiency gains.
- In 1997, the newly elected U.K. Labour Party government imposed a one-time 23% 'windfall tax' on these privatized companies.
- The tax was calculated using a formula based on the company's total profits during the initial period (P), the length of that period (D), and its initial market sale value, known as flotation value (FV).
- The U.K. government characterized the tax as capturing the difference between the company's actual flotation value and a 'profit-making value,' which was calculated using the company's actual, realized profits from the initial period.
- South Western Electricity was assessed and paid a total windfall tax of £90,419,265.
Procedural Posture:
- PPL Corporation claimed a foreign tax credit on its 1997 U.S. federal income tax return for its share of the U.K. windfall tax.
- The Commissioner of Internal Revenue denied the tax credit.
- PPL challenged the denial in the U.S. Tax Court, which is a court of first instance.
- The Tax Court ruled in favor of PPL, holding that the tax was creditable.
- The Commissioner, as appellant, appealed the decision to the U.S. Court of Appeals for the Third Circuit.
- The Third Circuit reversed the Tax Court's decision, ruling in favor of the Commissioner, as appellee.
- The U.S. Supreme Court granted certiorari to resolve a circuit split on the issue.

Issue:
Does a foreign tax, characterized by the foreign government as a levy on the difference between a company's initial sale value and a retrospectively calculated 'profit-making value,' qualify as a creditable 'income, war profits, or excess profits tax' under Internal Revenue Code § 901 when its economic substance is a tax on realized profits above a certain threshold?
Opinions:
Majority - Justice Thomas
Yes. The U.K. windfall tax qualifies as a creditable excess profits tax because its economic substance, not its form or the foreign government's characterization, is controlling. The court must look to 'economic realities, not legal abstractions,' and the 'predominant character' of the tax is that of an income tax in the U.S. sense. The U.K.'s 'profit-making value' is a 'fictitious value' based entirely on realized net income. By algebraically rearranging the tax formula, the Court demonstrated that it is mathematically and substantively identical to a classic excess profits tax: a tax at a specific rate on profits (P) that exceed a threshold amount derived from the company's flotation value (FV). Because the tax is, in substance, a tax on profits, it satisfies the Treasury Regulations' tests and is creditable under § 901.
Concurring - Justice Sotomayor
Yes. The majority reaches the correct conclusion based on the arguments presented, but the analysis is fragile and becomes questionable when considering all taxpayers subject to the tax. The majority's algebraic rearrangement only works cleanly for the 27 companies that shared the same four-year initial period. For the five 'outlier' companies with different initial periods, the same rearrangement produces wildly different effective tax rates and profit thresholds, making the tax function more like a tax on average profits—a proxy for value—rather than a tax on total income. However, because the Commissioner conceded this point and did not properly raise the 'outlier' argument, it cannot be the basis for the decision, and thus concurring in the judgment is appropriate.
Analysis:
This decision strongly reaffirms the 'substance over form' doctrine within the context of foreign tax creditability, instructing courts to prioritize a tax's economic reality over the labels and formulas used by foreign governments. It establishes a significant precedent that a tax calculated using realized profits as a primary variable is likely to be deemed a creditable income tax, even if framed as something else. The concurrence, however, introduces a crucial caveat, highlighting the unresolved issue of how to apply the 'predominant character' test when a tax's structure affects a minority of taxpayers ('outliers') in a fundamentally different way, a question left for future cases.
