The Cross-Check Data Dispute: Does Your Counterparty's Expense Automatically Constitute Taxable Service Delivery for You?

Tax Ruling: VAT Base Adjustments and the Limits of Data Synchronization (Bank KBI Tbk Case)

The tax dispute between PT Bank KBI Tbk and the Directorate General of Taxes (DGT) highlights a crucial issue regarding the application of Article 4 paragraph (1) letter c of the VAT Law concerning the provision of Taxable Services. The primary focus of this case lies in the validity of the adjustment to the VAT Base (DPP) for the October 2018 tax period, amounting to IDR 14,708,096,547, which the Respondent initiated solely based on external data synchronization—specifically, expenses recorded by counterparties—without being supported by concrete cash flow evidence on the Petitioner’s side.

The Core Conflict: Substance Over Form vs. Third-Party Data

The core conflict arose when tax authorities identified service expenses recorded by the Petitioner’s counterparties that were not reported as deliveries in the Petitioner's VAT returns. The Respondent argued that based on Article 12 paragraph (3) of the KUP Law, such data serves as evidence of taxes owed but not paid. Conversely, the Taxpayer countered vigorously, stating that tax reporting must be based on actual transactions (substance over form). The Petitioner emphasized that the external data contained administrative errors and did not reflect actual service deliveries during the relevant period.

Judicial Consideration: The Burden of Proof on the Respondent

In its legal considerations, the Board of Judges emphasized that in an evidentiary dispute, the burden of proof rests with the Respondent to accurately demonstrate the existence of the adjusted tax object. Through a thorough evidence examination process, the Board identified that some of the data used by the Respondent was irrelevant to the tax period in dispute or consisted of transactions reported in different periods. This proves that tax information system data synchronization cannot serve as the sole basis for adjustments without further verification of the substance.

Implications: The Need for Material Validation

The implications of this decision reaffirm that Taxpayers have the right to challenge adjustments based on third-party data assumptions. This "Partially Granted" verdict provides a valuable lesson for the banking sector to consistently strengthen reconciliation documentation. Although the Board overturned part of the adjustment, the remainder was upheld because the Taxpayer could not provide sufficiently strong supporting evidence, demonstrating that the completeness of transaction supporting documents remains the primary key to winning tax litigation.

Conclusion

In conclusion, the accuracy of data within the DGT information system still requires material validation. Taxpayers are advised to mitigate risks through regular reconciliations to avoid data discrepancies that could potentially trigger similar disputes in the future.
