Estimated Data is Not Actual Revenue: The Failure of DGT's Extrapolation Correction in Tax Court

VAT Dispute Analysis: Managerial Estimates vs. Audited Realization (PT NSI)

The correction of the VAT Base (DPP) amounting to IDR 5,234,331,026.00 performed by the Respondent was based on the discovery of internal data in the form of a "Summary Sales" excel file, which was deemed to reflect unreported sales. The Respondent applied extrapolation techniques to this data to determine the value of deliveries that should have been subject to VAT, referring to the provisions of Article 4 paragraph (1) and Article 13 paragraph (5) of the VAT Law. However, this method faced a serious challenge in terms of evidentiary weight during the trial when confronted with actual realization data that had been independently audited.

The Conflict: Projections and Budgeting vs. Accounting Reality

The core of the conflict in this dispute centered on the difference between managerial data (sales estimates) and accounting data (actual shipment of goods). The Respondent believed that the "Summary Sales" data was authentic evidence from the Petitioner's internal system indicating hidden income. Conversely, PT NSI as the Petitioner emphasized that the data was merely a projection or budgeting that recorded orders, not actual sales realization. The Petitioner presented a comprehensive reconciliation aligning the data in the VAT Return with the audited Financial Statements, proving that all outgoing goods had been issued Tax Invoices.

Judicial Review: The Superiority of Audited Financial Statements

The Board of Judges opined that in making a correction, the tax authority must rely on competent evidence and in accordance with the actual circumstances as regulated in Article 76 of the Tax Court Law. Based on an in-depth examination of the flow of goods and money, the Board found that the Petitioner successfully proved that the data used by the Respondent was only a sales plan that was not physically realized in the March 2020 Tax Period. The Board of Judges assessed that Financial Statements audited by a Public Accountant with an Unqualified Opinion have higher evidentiary power compared to raw excel data whose actual validity has not been verified.

Implications: Defending Against Presumptive Corrections

The implication of this decision confirms that the use of extrapolation techniques or internal managerial data by the DGT cannot stand alone without verification of the actual flow of goods. This decision serves as an important precedent for Taxpayers to always maintain a strong reconciliation between internal systems and commercial financial statements. The absolute victory of the Petitioner in this case proves that audited accounting documentation and consistent evidence of the flow of goods are the most effective legal defense instruments against presumptive corrections.
