Taxpayer Wins Fully: 100% Correction of Affiliated Service Fees Overturned Due to Strong Arm’s Length Principle Evidence

In the context of transfer pricing implementation, Tax Court Decision Number PUT-001999.15/2020/PP/M.IIIA Tahun 2022 establishes an important precedent regarding the validity of intra-group service transactions. The case of PT SI highlights the complexity of proving the benefit test and the Arm’s Length Principle (ALP) in Corporate Income Tax (CIT) disputes, especially when the tax authority unilaterally corrects all affiliated service expenses based on Article 9 paragraph (1) letter f of the CIT Law.

The core conflict originated from a correction of USD 1,200,177.00 on service fees paid by PT SI to affiliated parties (SCorp and S HK) and an independent third party. The Tax Authority (Terbanding) argued that the services did not provide any real or economic benefit (failed benefit test) and that the Taxpayer failed to prove the actual detailed costs (cost base) incurred by the service provider (failed need test). Based on this assumed failure, the Tax Authority corrected the entire expense to zero, treating it as a payment exceeding fair value to shareholders (disguised dividend).

PT SI’s rebuttal centered on compliance with the ALP and Article 18 paragraph (3) of the CIT Law. PT SI presented comprehensive Transfer Pricing Documentation (TP Doc), proving that the services (such as purchasing, sales, and IT/ERP system) were real and vital for business operations. Through an analysis using the Transactional Net Margin Method (TNMM) and a Berry Ratio indicator of 1.92, the Taxpayer demonstrated that their profitability was above the upper quartile of comparable companies, confirming that the service price paid was at arm’s length. Furthermore, PT SI highlighted the Tax Authority’s error in using Article 9 paragraph (1) letter f of the CIT Law to correct transactions with an independent third party, which was a fundamental legal mistake.

The Tax Court Judges, in their deliberation, upheld the Taxpayer's arguments. The Judges were convinced that the Taxpayer had proven the existence of the services and the benefits obtained. The use of the Berry Ratio analysis successfully demonstrated that the transaction was within the arm's length range. Critically, the Judges also affirmed that the correction of the entire expense (100%) for costs that had been proven to be at arm’s length was illogical and inconsistent with the principle of prudence. The Judges' decision to fully grant PT SI’s appeal directly nullified the Tax Authority’s full correction of the service fees.

The implications of this decision for tax practice confirm that robust transfer pricing documentation is the primary line of defense for taxpayers. The ruling serves as a reminder to the tax authority that the rejection of the entire amount of intra-group service expenses must be based on a more thorough analysis of arm’s length pricing, consistent with OECD guidelines, rather than merely rejecting the claim due to a lack of cost details. Taxpayers, especially multinational entities, must ensure their TP Docs include not only comparable analysis but also substantive and detailed evidence of the benefit test and cost allocation.
