Statistical Intervals in Transfer Pricing: An Analysis of EET

On February 23, 2026 Asger Kelstrup's article analysing the EET decision was published in Tax Notes International.

In this article for Tax Notes International, Asger Kelstrup examines the Danish Supreme Court’s EET decision on transfer pricing ranges. The Court accepted use of a full range in a gross-margin benchmark where observations were few and comparability defects unproven. The case clarifies that interquartile ranges are a tool to improve comparability defects, not a mandate. The article contrasts the ruling with OECD guidance, reviews the use of a range in Danish and EU case law, and outlines practical takeaways. In short, let functional comparability drive method and metrics, document adjustments transparently, and reserve statistical narrowing for identified defects.
