A SAP Currency Input Error Led to a IDR 27 Billion Tax Correction for PT TDASI: How Did the Judges Rule?

Equalization vs. Human Error: Analyzing the PT TDASI Income Tax Article 23 Dispute

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.

The Conflict: SAP System Currency Error and the June 2017 Accumulation

The conflict began when the Directorate General of Taxes (DJP) performed an equalization between the Income Tax Article 23 objects reported in the Tax Return (SPT in Indonesian) and the Repair & Maintenance - IT expense accounts. The DJP found a significant discrepancy and immediately designated it as the Tax Base (DPP in Indonesian) for Income Tax Article 23. 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 DJP's action of accumulating a full year's worth of potential tax into a single tax period (June 2017).

Judicial Resolution: Distinguishing Accounting Balances from Taxable Events

In its consideration, the Panel of Judges emphasized that DJP 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 Panel concluded that PT TDASI'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 DJP to be meticulous in distinguishing between administrative accounting account balances and the actual taxable event (taatbestand).

Strategic Implications: Data Integrity and Clear Audit Trails

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.
