Economic Substance in Turnkey EPC Contracts and Masterlist Facilities: CSTS JO VAT Dispute

Tax disputes worth billions of rupiah often arise from differing interpretations between tax authorities and taxpayers regarding Value Added Tax (VAT) treatment in national strategic projects, specifically concerning Masterlist facilities. The case of CSTS JO against the Directorate General of Taxes (DGT) serves as a crucial case study on how the economic substance of Engineering, Procurement, and Construction (EPC) contracts must take precedence over mere administrative formalities. The core conflict began when the Respondent (DGT) made a positive correction to the VAT Tax Base (DPP) for December 2022 amounting to IDR 50.4 billion, arguing that the delivery of imported goods using the Masterlist facility (VAT not collected) should still be subject to VAT as it was considered part of the gross contract value delivered to the VAT Collector (B Ltd.).

The Respondent's Accounting Classification Challenge and the Petitioner's Rebuttal

The Respondent argued that CSTS JO did not meet the criteria for pure reimbursement because it recorded the goods as inventory and revenue in its books. However, the Petitioner (CSTS JO) provided a strong rebuttal by referring to specific upstream oil and gas industry regulations and a series of previous DGT rulings stating that for turnkey contracts, the value of Masterlist goods in the name of the project owner is not a VAT Base for the contractor. The Petitioner successfully demonstrated precise reconciliation evidence between import declaration documents (PIB), approved Masterlist facilities, and the values deducted from billings to B.

In Its Legal Considerations the Tax Court Judges Assert Substance Over Form

In its legal considerations, the Tax Court Panel of Judges emphasized the principle of substance over form. The Panel assessed that since this was an integrated project, the change in the form of goods after the construction process is natural and should not be used as a reason to deny the "VAT not collected" facility. Furthermore, the audit results on the counterparty (B) showed consistent compliance, where there were no objections from the collector regarding the tax invoice mechanism issued by the Petitioner. This legal resolution ended with the cancellation of all the Respondent's corrections, confirming that taxpayer rights to state facilities must be protected as long as material evidence is accountable. The implication of this decision provides legal certainty for EPC contractors that the mechanism of deducting Masterlist values from the VAT Base is legally valid and cannot be corrected solely based on accounting account classifications as long as the substance of the transaction is clear.
