Why Cost Equalization Alone is Not Enough to Charge Taxpayers?

PT KI Tax Dispute: Positive Correction on Article 23 Income Tax Objects via Cost Equalization Mechanism

The Director General of Taxation (DGT) issued a positive correction of IDR 1,676,705,050 for Article 23 Income Tax objects for the March 2018 tax period of PT KI through a cost equalization mechanism, leading to a dispute at the Tax Court. The conflict originated from the Respondent's findings, which compared cost balances in the General Ledger with the Article 23 Tax Returns, where the discovered discrepancy was considered an unreported tax object. The Respondent insisted that during the objection process, the Taxpayer failed to provide adequate details to refute the assumption, thus the correction was maintained to secure state revenue based on Article 12 paragraph (3) of the KUP Law.

Applicant's Rebuttal: Cost Components Reality, Regulatory Exclusions, and USD Bookkeeping Impact

PT KI, as the Applicant, strongly refuted this method by presenting concrete evidence during the court hearings. The Taxpayer's main argument focused on the fact that the equalization difference was not an Article 23 Income Tax object but consisted of driver's salary components (part of vehicle rental costs), apartment rentals subject to Final Income Tax Article 4 paragraph (2), and goods/material purchases which are regulatory excluded from Article 23 objects under PMK 141/PMK.03/2015. Furthermore, there were elements of accrued expenses and exchange rate differences arising because the company's bookkeeping used US Dollars (USD) while tax reporting used IDR, making nominal figure comparisons irrelevant without technical adjustments.

Judicial Considerations: Board of Judges Overturns Global Equalization Due to Lack of Specific Transaction Tracing

The Board of Judges, in its legal consideration, emphasized that the burden of proof for the correctness of the adjustment lies with the Respondent. The Judges assessed that the Respondent did not perform a detailed transaction-by-transaction trace and merely relied on global equalization techniques for a single tax period (March 2018) regarding the full-year cost difference. The Board opined that since the Applicant had submitted the required documents during the audit, the Respondent should have been able to specifically prove each corrected item as a tax object, rather than relying on numerical assumptions. Based on supporting evidence such as invoices and Final Tax withholding slips presented by the Taxpayer, the Board concluded that the Respondent's correction lacked a strong factual basis.

Strategic Implications: Equalization as an Initial Analytical Tool and Reinforcement of Substance Over Form

The Board of Judges' decision to fully grant the appeal sends a strong message to tax authorities and practitioners. This ruling reaffirms that equalization is merely an initial analytical tool and not absolute proof of an outstanding tax liability. For Taxpayers, this victory demonstrates the critical importance of robust documentation and neat account separation between tax-exempt and non-tax-exempt objects during audits. The implication is that tax audits must return to the corridor of substance over form and meticulous document tracing to ensure fairness for the Taxpayer.
