Head Office Input Tax May Not Be Fully Creditable for Mixed Supplies

Tax Ruling: Mixed Supplies and the Implementation of the Pro-Rata VAT Mechanism (PT PPI Case)

The tax dispute between PT PPI and the Directorate General of Taxes (DGT) highlights the complexity of implementing Article 9, paragraph (5) of the VAT Law regarding Input Tax credits for entrepreneurs with mixed supplies. The central focus of this case is the interpretation of joint costs at the Head Office used to support business units with different VAT statuses: taxable supplies and VAT-exempt supplies.

The Core Conflict: Joint Costs and the Crediting of Input Tax

The core of the conflict began when the DGT made a positive correction to PT PPI's Head Office Input Tax for the December 2021 Tax Period, amounting to IDR 313,384,140.00. The tax authority argued that since PT PPI operates a electricity sales business line that is VAT-exempt (PLTBg Sei Mangkei) alongside taxable PLTS rental services, the Input Tax on general Head Office operational costs cannot be fully credited. The DGT applied a proportionality formula in accordance with PMK 78/2010, asserting that these costs could not be definitively separated. Conversely, PT PPI insisted that they had implemented systematic separate bookkeeping within their SAP system, whereby only Input Tax related to taxable units was credited.

Judicial Consideration: Testing the "Direct-Use" Principle

The Tax Court Judges, in their legal considerations, emphasized that proving "separate bookkeeping" requires more than just a systematic claim; it must be reflected in actual field usage. The judges found evidence during the trial that certain Head Office expenses were still substantially related to the infrastructure development of the exempt business unit. Since PT PPI could not provide detailed evidence that these Head Office costs were 100% for taxable supplies, the Panel supported the DGT's decision to apply proportional recalculation to ensure fairness to the state and legal certainty for the taxpayer.

Implications and Conclusion

The implications of this ruling serve as a stern warning for companies with diverse supply structures to be more meticulous in classifying Input Tax from the procurement stage. Failure to prove a direct link between Input Tax and taxable supplies will force taxpayers to submit to a pro-rata mechanism, which often disadvantages the company's cash flow position. In conclusion, the Panel's firm stance demonstrates that the "direct-use" principle in VAT remains the primary instrument for testing the validity of Input Tax credits.
