Beware of Proportional VAT Corrections: Lessons from the Head Office Input Tax Credit Dispute of PT PPI

VAT Dispute: Input Tax Credit for Mixed Activities, Joint Costs at Head Office, and Proportional Recalculation for PT PPI

The Value Added Tax (VAT) dispute between PT Pertamina Power Indonesia (PPI) and the Directorate General of Taxes (DGT) provides a crucial precedent regarding the requirements for Input Tax credit for companies with mixed delivery structures (mixed activities). The focus of the dispute centers on the correction of Input Tax for the February 2021 Tax Period amounting to IDR 180,768,857.00 carried out by the Respondent through a proportional recalculation method. The DGT argued that operational costs at the Head Office are joint costs that support all business units, including units whose deliveries are exempt from VAT, such as electricity sales from the Sei Mangkei Solar Power Plant (PLTS).

Core Conflict: SAP System Accounting Separation vs. Joint Managerial Functions

In its rebuttal, PT PPI emphasized that it had implemented strict accounting separation principles using the SAP system to identify the allocation of each Input Tax with certainty (direct-use). The Petitioner claimed that the Input Tax credited at the Head Office only related to VAT-taxable activities, while Input Tax for exempt business units had been reported separately in Appendix B3 of the VAT Return. However, during the evidence process in court, it was revealed that several tax invoices credited at the Head Office were actually related to the construction of power plants whose future deliveries would be exempt from VAT.

Judicial Resolution: The Imperative Use of PMK 78/PMK.03/2010 Guidelines

The Tax Court Judges provided a legal opinion focusing on the substance of the evidence regarding cost separation. The Assembly assessed that the administrative role of the Head Office is inherently difficult to separate from the managerial functions of all business units. Since the Petitioner could not present accounting data that exclusively proved that the Head Office Input Tax was not used at all for exempt activities, the use of the Input Tax Crediting Calculation Guidelines according to PMK Number 78/PMK.03/2010 became imperative. The Judges ultimately rejected PT PPI's appeal, confirming that the inability to separate costs physically and administratively results in proportional correction.

Implications: Necessity of Material Evidence in ERP Transaction Codification

This decision has serious implications for Taxpayers who have business lines with different VAT treatments. Failure to prove specific Input Tax allocation per transaction will force the use of a proportional formula, which is often financially disadvantageous. In conclusion, companies must ensure that transaction codification in ERP systems is not only accounting-compliant but also supported by material evidence showing that the acquisition of taxable goods/services at the Head Office truly has no role in the operation of units whose deliveries are non-taxable or VAT-exempt.
