Countering Tax Corrections Without Direct Sales Evidence: Lessons from the PT SBS Case

Indirect Audit Methods & The Gross-Up Function: Analyzing PT SBS’s Unreported Turnover

Unreported business turnover often becomes a complex dispute due to the scarcity of direct transaction data. In the dispute between PT SBS and the Directorate General of Taxes (DGT), the tax authority employed the gross-up technique on discovered Input VAT to calculate potential Value Added Tax (VAT) that remained uncollected. The Defendant applied Article 2 letter h of PMK-15/PMK.03/2018, which permits the calculation of gross turnover through "other methods" when the taxpayer's records are deemed unreliable.

The Conflict: One-Sided Assumptions vs. Third-Party Confirmation

The core conflict centered on the Plaintiff's argument that such corrections were merely assumptions or one-sided analysis. The Plaintiff emphasized that the DGT failed to prove the existence of physical delivery to specific buyers, which is an absolute requirement for VAT imposition under Article 4 paragraph (1) of the VAT Law. However, the Defendant refuted this defense by presenting confirmation evidence from third-party suppliers who validated that the purchase transactions were indeed carried out by the Plaintiff, despite not being recorded in their tax returns.

Judicial Consideration: The Validity of Goods-Flow Testing

The Board of Judges, in its legal consideration, affirmed that indirect methods through goods-flow testing and ratio techniques are legally valid. The Judges reasoned that since the Plaintiff could not concretely prove that the Input VAT data belonged to another party or resulted from identity theft, the goods were legally presumed to have been controlled and subsequently delivered by the Plaintiff.

Implications: The Power of Third-Party Data

This decision carries significant implications for taxpayers to be more diligent in managing Input VAT and to recognize that the DGT has the authority to estimate business turnover based on third-party data. Bookkeeping transparency remains the ultimate key to avoiding corrections based on indirect calculation methods, which often result in substantial tax liabilities.

The final ruling rejected the Plaintiff's lawsuit entirely because the evidence submitted by the Defendant was considered stronger and met the evidentiary standards in tax procedural law.
