Why Government Benchmark Prices Can Prevail Over Tax Corrections? 

Transfer Pricing Dispute of PT JBG: Application of the CUP Method and Coal Benchmark Price (HPB) Regulations

The application of the Arm's Length Principle (ALP) to affiliated transactions in the coal mining sector often triggers complex interpretative disputes regarding transfer pricing methods between the Respondent and the Taxpayer. In the case of PT JBG, the core conflict centered on the Respondent's use of the Comparable Uncontrolled Price (CUP) method, utilizing external indices (ICI) to adjust coal sales prices to affiliates in Thailand. The Respondent insisted that the Petitioner's selling price was below the market price after quality adjustments, while the Petitioner asserted that the transactions complied with the Coal Benchmark Price (HPB) regulations set by the Ministry of Energy and Mineral Resources as a CCOW (PKP2B) holder.

Legal Resolution of the Board of Judges: Accuracy of Comparable Data and Sectoral Regulatory Constraints

The legal resolution adopted by the Board of Judges emphasized the accuracy of comparable data and the recognition of sectoral regulatory constraints. The Board opined that the Respondent's correction, which relied solely on publication indices without considering specific contracts and the obligation to comply with government pricing, could not be fully upheld. The Board conducted a thorough evaluation of each transaction and found that most of the Petitioner's selling prices were actually within the arm's length range when using more precise comparison parameters. Consequently, this decision reinforces that tax authorities cannot ignore sectoral regulations (such as HPB) and must be more cautious in making adjustments within the CUP method to avoid producing corrections that are estimative and speculative in nature.
