Internal CUP Warnings! PT BEU Wins Transfer Pricing Dispute Against the DGT 

PT BEU Transfer Pricing Dispute: Application of the CUP Method and Comparability of Related-Party Transactions

Tax authorities frequently exercise their authority under Article 18 paragraph (3) of the Income Tax Law to adjust related-party transactions by applying the Comparable Uncontrolled Price (CUP) method. In the case of PT BEU, the Respondent imposed an operating revenue correction of IDR 4.93 billion after comparing the sale price of products to an affiliated distributor against the price sold to a single independent buyer. The Respondent argued that the significant price disparity proved a lack of arm's length compliance, which eroded the national tax base through transfer pricing mechanisms inconsistent with the Arm's Length Principle (ALP).

Core Conflict: Objectivity of Comparable Data and Volume Disparities

The core of the conflict centers on the objectivity of the comparable data used in the comparability analysis. The Respondent used a transaction with DB as the sole comparable, whereas the Petitioner emphasized that the transaction amounted to only 3 kg and was purely incidental. In contrast, transactions with PT IJ (affiliate) were routine, with volumes reaching tens of thousands of kilograms. The Petitioner contended that pursuant to PER-32/PJ/2011, highly minuscule and non-routine transactions cannot serve as a benchmark to evaluate the fairness of primary transactions that possess vastly different functional and risk profiles.

Judicial Ruling: High Comparability Standards and Adjustments in the CUP Method

The Board of Judges, in its resolution, provided a firm legal opinion that the application of the CUP method requires a very high level of comparability or accurate adjustments for existing differences. The Board assessed that the volume difference—thousands of times greater between the affiliate and independent transactions—created a price distortion that could not be ignored. Since the Respondent failed to prove that the transactions were substantially comparable and did not perform adjustments for differences in function and volume, the Board of Judges ruled to vacate the Respondent's entire correction.

Key Implications: Internal CUP Usage and Transfer Pricing Documentation

The implications of this decision provide legal certainty for taxpayers that the use of internal comparables (internal CUP) must not be conducted arbitrarily. This ruling reinforces the importance of in-depth comparability analysis, particularly regarding aspects of quantity and transaction frequency. For tax practitioners, this case serves as a precedent that robust Transfer Pricing Documentation (TP Doc) must be able to distinguish between retail/incidental transactions and commercial distribution transactions to avoid corrections that lack a basis in economic reality.
