Taxpayer Wins Case! Tax Court Annuls VAT DPP Correction Based on Erroneous Average Price Testing Methodology

The tax dispute involving CV GC and the Director General of Taxes (DGT) highlights the complexities of determining the Value Added Tax (VAT) Tax Base (DPP), particularly in the trading sector characterized by high price fluctuations. The core conflict centered on a VAT DPP correction of IDR4,991,708,354, which the DGT based on comparing the unit price between sales issued with e-Invoices (typically wholesale) and sales summarized in simplified VAT invoices (retail). The Tax Court ruled that this correction contradicted the business judgement rule as stipulated in PSAK 23 (Statement of Financial Accounting Standards).

Core Conflict: Unreported Turnover Assumptions vs. Market Price Realities (True Price)

The DGT argued that the systematic price difference indicated unreported business turnover. The correction was performed because the Taxpayer was deemed unable to formally substantiate claims of discounts or supplier cashback that affected the final selling price, leading the DGT to invoke its correction authority under Article 12(3) of the KUP Law. Conversely, the Taxpayer firmly maintained that the reported selling price was the actual price received after accounting for incentives and the differing market conditions between retail and wholesale.

Judicial Resolution: Audit Methodology Hierarchy and the Scope of Statistical Testing

The Tax Court explicitly stated in its Decision that the audit method used by the DGT—comparing average prices over a year—was an indirect method that should not have been utilized. The DGT is bound by the audit hierarchy; if proper books and records are available, the direct method must be prioritized. The Court judged that testing the average price for highly volatile products like mobile phones was irrelevant and invalid, as it ignored justifiable business dynamics such as discounts. Consequently, the Court ruled to cancel this unit price correction, reinforcing the legal protection for legitimate business practices under tax law.
