Warning! Unreported Input Tax Can Trigger Revenue Corrections: The Hard Lesson Learned by PT SBS at the Tax Court

Indirect VAT Base Corrections: Analyzing the PT SBS Gross-Up Dispute

Value Added Tax (VAT) base corrections based on indirect methods, specifically the gross up of unreported input tax findings, often represent a critical juncture in Tax Court disputes. In the case of PT SBS, the Directorate General of Taxes (DGT) applied a positive correction to business turnover after identifying purchase transactions through invoice confirmation data from counterparties that were not recorded in the Taxpayer’s accounting records.

The Conflict: Gross-Up Methodology vs. Concrete Evidence

The core of the conflict in this case centers on the validity of the gross up method employed by the Defendant. The DGT argued that the existence of unreported taxable goods purchases automatically implies that those goods were subsequently sold without being reported (the "goods out" assumption). Conversely, PT SBS, as the Plaintiff, countered that such corrections were merely analytical and lacked concrete evidence of actual delivery, buyer identity, or cash inflows as mandated by Article 4 of the VAT Law.

Judicial Consideration: The Presumption of Transferred Goods

The Board of Judges, in their legal consideration, emphasized that tax invoice confirmation data from third-party vendors constitutes authentic evidence of purchase transactions. Since the Plaintiff could not prove the physical existence of these goods as inventory in their warehouse, the Judges upheld the legal assumption that the goods had been transferred or delivered to another party. The application of an 8.9% Gross Profit Margin in the gross up method was deemed reasonable.

Implications: The Criticality of Internal Reconciliation

This decision carries significant implications for Taxpayers, particularly regarding the integrity of recording every input tax invoice received. Juridically, this ruling strengthens the tax authority's position in utilizing indirect calculation methods when a Taxpayer’s records are deemed incomplete. The PT SBS case serves as a stark reminder for companies to perform regular reconciliations between internal data and the DGT’s e-Faktur system.

Risk mitigation strategies should focus on strengthening internal control systems over transaction documents to ensure all movement of goods can be legally accounted for.
