Oil & Gas PE Tax Dispute: BP East Kalimantan Ltd Prevails in 10% Treaty Rate Claim

BP Ltd Branch Profit Tax Dispute: Supremacy of the Indonesia-UK Tax Treaty over Domestic Tax Rates

The Branch Profit Tax (BPT) dispute between BP Ltd and the Director General of Taxation serves as a crucial precedent regarding the supremacy of Double Taxation Conventions (DTC) over domestic regulations in the extractive industry. The conflict originated from the Respondent's adjustment, which applied a 20% Income Tax Article 26 (4) rate on 2013 after-tax profits. The Respondent argued that the Sanga-Sanga Production Sharing Contract (PSC), signed in 1990, must maintain fiscal balance aligned with the 85:15 split, suggesting that applying the treaty rate would disrupt the state's revenue share.

Petitioner's Defense: 10% Preferential Rate Rights and Tax Treaty Supremacy

Conversely, the Petitioner asserted its right to utilize the 10% preferential rate under Article 10 (7) of the Indonesia-UK Tax Treaty. The Petitioner’s argument focused on the fact that the Sanga-Sanga PSC was signed on April 23, 1990, meaning the contract does not fall under the exception in Article 10 (8) of the Treaty, which only protects contract rates signed before December 31, 1983. The Petitioner emphasized that based on Article 1338 of the Indonesian Civil Code and international law principles, ratified treaty provisions must be honored as lex specialis.

Judicial Considerations: Enforcement of Treaty Rates and Legal Certainty for Energy Investors

The Board of Judges, in its legal consideration, agreed with the Taxpayer's position. The Judges ruled that there were no provisions in the Sanga-Sanga PSC explicitly prohibiting the use of generally applicable treaty rates. Since the contract was executed after 1983, the 10% rate cap in the Indonesia-UK Tax Treaty must be upheld. The final verdict granted the appeal in its entirety, confirming that production sharing assumptions in oil and gas contracts cannot automatically override international tax facilities unless specifically regulated in contract clauses or treaty protocols. This decision provides legal protection for oil and gas investors regarding tax rate certainty under international agreements.
