Strategy in Facing Transfer Pricing Adjustments: Why the Median Point is Fairer Than the Third Quartile?

Transfer Pricing Dispute: TNMM Methodology, Interquartile Range, and Multiple-Year Data Analysis for PT SIWS

The transfer pricing dispute regarding PT SIWS focused on testing the arm’s length nature of operational profits through the Transactional Net Margin Method (TNMM) for the 2021 Fiscal Year. The tax authority (Respondent) made a significant adjustment by setting the arm’s length point at the Third Quartile (Q3) and using single-year comparable data, triggering a drastic difference in transaction value.

Core Conflict: Comparability Parameters and COVID-19 Specific Factor Adjustments

The main conflict lay in the difference of comparability parameters, where the Taxpayer maintained the use of multiple-year data (2018-2020) and specific factor adjustments (SFA) due to the COVID-19 pandemic and new product line costs. The Tax Court, in its decision, took a middle ground by rejecting the SFA but strictly overturning the Respondent's use of the Q3 point.

Judicial Resolution: Shifting from Third Quartile (Q3) to Median (Q2)

The legal resolution established that the Median point (Q2) of 3.81% is a more accurate reflection of market conditions, given that the Respondent failed to prove the Taxpayer's position as a dominant market leader. This decision reaffirms the importance of consistency in using multiple-year data to mitigate economic fluctuations and the need for a strong argumentative basis when determining a point within the arm’s length range.
