Judges Overturn Revenue Correction Based Solely on Extrapolation Assumptions

Cancellation of VAT Output Correction Based on Extrapolation Methods: The Demand for Micro-Transaction Evidence Accuracy

Tax authorities cannot determine tax liability based solely on extrapolation methods without the support of concrete and valid micro-transaction evidence. This dispute focuses on the correction of VAT Output for PT PZU based on assumed motor vehicle sales volumes, which was subsequently fully overturned by the Tax Court's Board of Judges.

Case Origin: Audit of February 2015 Tax Period and Vehicle Registration Data Discrepancies

The case originated when the Respondent (DGT) conducted an audit of PT PZU for the February 2015 tax period. The Respondent believed there were unreported vehicle deliveries based on external vehicle registration data. Using an extrapolation method, the Respondent concluded there was a turnover discrepancy and assessed additional VAT Output. Conversely, the Taxpayer asserted that every unit leaving the dealership had a Tax Invoice issued and reported in the tax returns, rejecting the extrapolation results which failed to account for order cancellations and administrative timing differences.

The Core Legal Conflict: Burden of Proof and Objective Audit Standards Under Article 12 KUP Law

The core of this legal conflict lies in the burden of proof and audit methodology. The Respondent relied on extrapolated macro data without dissecting the cash flow or document trail per transaction. The Taxpayer argued that Article 12 paragraph (3) of the KUP Law requires tax assessments to be based on objective audit results, rather than mere statistical assumptions.

Judicial Deliberation: Inadequacy of Statistical Assumptions and Material Evidence Requirements

In its legal considerations, the Board of Judges stated that the extrapolation method used by the Respondent was inadequate to prove the actual delivery of Taxable Goods. The Judges emphasized that to correct turnover, the Respondent should have presented specific evidence of cash flow or goods flow for each unit deemed unreported. As the Respondent failed to provide such material evidence, the Board of Judges decided to grant the Taxpayer's appeal in its entirety.

Ruling Implications: Clear and Convincing Evidence for Validating External Comparisons

The implication of this decision reinforces that legal certainty in taxation requires clear and convincing evidence. For taxpayers, this victory provides a precedent that audit results relying solely on rough external data comparisons without factual verification can be annulled in court.
