A Landmark Offshore Industry Ruling: Reassessing Final Income Tax on Rig Manufacturing

The dispute over the classification of business activities and the application of Final Income Tax under Article 4(2) has once again become a significant issue in the appeal filed by PT GTI against the Directorate General of Taxes (DGT) regarding the Final Income Tax correction for the Tax Period of February 2019. The case originated when the DGT imposed a positive adjustment to the Tax Base amounting to Rp152,241,327,630.00, which the DGT considered as income derived from the construction of a jack-up rig, thereby subject to Final Income Tax on construction services. This correction triggered a debate over whether the manufacturing of a jack-up rig truly constitutes construction work as defined under tax regulations and construction service laws.

During the audit, the DGT argued that export documents (PEB) and production data indicated construction activities that generated taxable income for PT GTI. However, the DGT also acknowledged that a substantial portion of the supporting documents—such as third-party vendor invoices, cost breakdowns, and other records requested during the audit—were not available. This lack of documentation was used as the basis for maintaining the correction, under the assumption that the values reported in the PEB represented transaction values that reflected income earned by PT GTI.

PT GTI strongly rejected this correction. According to the company, a jack-up rig is an industrial vessel whose manufacturing falls under the regime of industrial fabrication rather than construction services. PT GTI emphasized that the characteristics of jack-up rigs—including their mobile and non-permanent nature—contradict the definition of “construction works” as stipulated under the Construction Services Law. PT GTI further explained that the PEB values did not necessarily represent income, as they may include the value of goods or other components that do not constitute taxable services. The company also asserted that it had provided relevant documents, and the DGT lacked adequate evidence to recharacterize the entire value as the tax base for final tax purposes.

Upon examination, the Tax Court Panel concluded that the DGT failed to demonstrate that the amount of Rp152,241,327,630.00 was income actually earned by PT GTI. The Panel further held that the legal basis applied by the DGT was inappropriate, as the manufacturing of a jack-up rig does not satisfy the elements of construction work under the applicable regulations. Consequently, the evidentiary burden that should have been fulfilled by the DGT was deemed not met.

Based on these considerations, the Tax Court Panel granted the appeal in full and declared that the DGT’s correction of Final Income Tax under Article 4(2) was incorrect, thereby cancelling the entire correction of Rp152,241,327,630.00. This ruling underscores the critical role of proper documentation in final tax disputes and reaffirms that the classification of construction activities is not determined solely by the physical nature of an object, but by how the regulations define the scope of construction work.
