Why the Tax Office Cannot Simply Guess VAT Turnover Based on Last Year's Data?

Tax Dispute: VAT Correction, Extrapolation Methodology, and Material Evidentiary Standards for PT MRP

The correction of the VAT Base (DPP) for the March 2020 Tax Period against PT MRP was based on an extrapolation method derived from 2018 tax audit findings regarding raw material usage. The Respondent (DGT) believed there were unreported deliveries because the Taxpayer could not detail material usage per item, leading the DGT to use historical variance percentages as the basis for the new tax assessment.

Core Conflict: Validity of Indirect Calculation Methods vs. Independent Tax Periods

The core conflict in this case lies in the validity of using indirect calculation methods (extrapolation) by the tax authorities. The Respondent argued that the lack of clear production data provides the authority to perform estimations. Conversely, the Petitioner emphasized that each tax period is independent, and corrections without evidence of actual cash flow or goods flow in the relevant tax period violate the principles of legal certainty and material evidence.

Judicial Resolution: Standards of Evidence and the Rejection of Cross-Year Assumptions

In its legal consideration, the Board of Judges stated that an extrapolation method jumping across different tax years cannot serve as the sole basis for correction. Pursuant to Article 76 of the Tax Court Law, judges must decide based on at least two sufficient pieces of evidence and the judge's conviction. The absence of concrete evidence, such as account receivables or cash inflows showing shadow sales transactions in March 2020, caused the Respondent's assumptions to fail in court.

Implications: Burden of Proof and the Prevalence of Substantive Justice

The implication of this decision reinforces that the burden of proof regarding unreported income rests with the tax authorities. Taxpayers should not be taxed based on probabilistic assumptions without strong material facts. This ruling serves as an important precedent for manufacturing companies to maintain the integration of production and sales data to counter "yield-based" audits or extrapolations.

In conclusion, the Board of Judges overturned the Respondent's entire correction as it did not meet the evidentiary standards required by Indonesian tax regulations. Substantive justice must prevail over mere administrative estimates that are not based on the reality of transactions.
