Challenging Unilateral Tax Assessments: PT SB Prevails in VAT Dispute Over Flawed Inventory Data 

VAT Dispute of PT SB: Reversal of VAT Base Correction Based on Speculative Material Flow Methods

The implementation of material flow tests by tax authorities often serves as a critical tipping point in determining the material truth of taxable deliveries. In the case of PT SB, the Respondent issued a VAT Base (DPP) correction amounting to IDR 2,088,613,554.00 using an indirect method approach, alleging unreported physical inventory discrepancies.

The Core Conflict: Yarn Movement Extrapolation vs. Commingled Tax Periods and Ignored WIP Balances

The conflict originated when the Respondent extrapolated yarn movement data for the May 2018 tax period. The Respondent claimed that 308.48 bales of yarn left the warehouse without being recorded as official sales. Conversely, PT SB argued that the Respondent's calculation contained fundamental errors by commingling transaction data between different tax periods and ignoring the existence of work-in-process (WIP) balances and legitimate third-party purchases.

Judges' Legal Deliberations: Inaccurate Inventory Assumptions and Legally Flawed Source Data

The Board of Judges, in its legal deliberations, discovered that the Respondent had included purchase data from PT TTI and PT PIT that administratively and factually only occurred in June 2018. Furthermore, the Respondent's assumptions regarding subcontracting (maklon) receipts from PT AIC were not supported by valid delivery notes or official reports. This inaccuracy rendered the material flow formula legally flawed as it failed to reflect the actual physical reality of the inventory.

Ruling Implications: Burden of Proof Shifts and the Critical Importance of Synchronized Warehouse Documents

This ruling underscores that the use of indirect methods in tax audits must not be speculative. When a Taxpayer can present more credible counter-evidence, such as Input Tax Invoices and consistent inventory movement reports, the burden of proof shifts to the Respondent to maintain data accuracy. The Respondent's failure to prove the validity of its data sources resulted in the total reversal of the correction by law.

In conclusion, PT SB's victory serves as a vital precedent on the importance of synchronizing warehouse operational data with financial reporting. Taxpayers are advised to maintain strict integrity of daily movement documents to mitigate the risk of adjustments based on inaccurate material flow assumptions by tax auditors.
