Assumption-Based Taxes Fail in Court: Why Palm Oil Production Estimates Cannot Be the Sole Basis for Tax Corrections?

PT TSS Revenue Dispute: Production Flow Testing vs. Factual Evidence

The revenue dispute of PT TSS originated from the Respondent's move to make a positive correction of IDR 48.15 billion using the production flow testing method. The Respondent assumed unreported Fresh Fruit Bunch (FFB) production by referring to land area data in the Land and Building Tax (PBB) documents and an average industry yield standard of 20-25 tons per hectare. However, this estimation method was strongly opposed by the Taxpayer, who stated that actual field production depends heavily on plant conditions and maintenance, not just administrative land area.

Evidence Validity and Data Consistency

The core of the conflict lies in the validity of the evidence used. The Respondent relied solely on productivity assumptions without conducting physical observations or having evidence of hidden real sales transactions. On the other hand, PT TSS successfully demonstrated data consistency between daily harvest reports, sales invoices, and confirmations from the counterparty (PT FB), showing that all harvests were correctly reported and taxed.

Judicial Deliberation and Legal Protection

The Board of Judges, in its legal consideration, emphasized that tax corrections must be based on competent evidence, as regulated in Article 12 paragraph (3) of the KUP Law. The Board assessed that the Respondent's method of using yield estimates from PBB data without evidence of actual goods delivery was inappropriate. This decision provides legal protection for Taxpayers against arbitrary or unilateral corrections without a strong basis of transaction evidence. The implication is that tax authorities must prioritize primary transaction document evidence rather than mere mathematical projections in determining business turnover.
