A SAP Currency Input Error Led to a Rp27 Billion Tax Correction for PT TDASI: How Did the Judges Rule?

Tax Court Dispute: PT TDASI Equalization Case

Tax corrections based solely on equalization techniques without the support of concrete transaction evidence often become a weak point in Tax Court disputes. The case of PT TDASI serves as a clear example where a technical error in the accounting system (human error) triggered a massive correction amounting to tens of billions of rupiah. This dispute centers on whether the results of expense equalization in financial statements can automatically be established as a tax object without clear identification of the specific income recipient.

Background of the Conflict and System Input Error

The conflict began when the Respondent performed an equalization between the Article 23 Income Tax objects reported in the Tax Return (SPT) and the Repair & Maintenance - IT expense accounts. The Respondent found a significant discrepancy and immediately designated it as the Tax Base (DPP) for Article 23 Income Tax. However, PT TDASI strongly disputed this by explaining a currency input error in the SAP system—where a Rupiah transaction was entered as USD—causing the value to inflate automatically by the system. PT TDASI asserted that reversal journals had been made and the actual transaction value was very small, while also protesting the Respondent's action of accumulating a full year's worth of potential tax into a single tax period (June 2017).

Considerations of the Board of Judges

In its consideration, the Board of Judges emphasized that tax authorities must possess sufficient competent evidence before making a correction, in accordance with applicable audit standards. After examining the journal evidence and audited financial statements, the Board concluded that the Petitioner's argument regarding the system input error was correct. The Judges held that equalization is merely an initial detection tool and cannot replace primary transaction evidence. This ruling reinforces the need for authorities to be meticulous in distinguishing between administrative accounting account balances and the actual taxable event (taatbestand).

Implications for Taxpayers

The implication of this decision for Taxpayers is the vital importance of maintaining the integrity of accounting system data and the ability to present a clear audit trail when input errors occur. Legally, this judgment strengthens the Taxpayer's position that tax corrections must not be based on mere assumptions or indirect approaches if they are not supported by material facts regarding the flow of income to a third party.
