Is Construction Certification Stronger Than the New Law? Analysis of the Taxpayer’s Defeat in the Final Income Tax Dispute over Submarine Cable Installation

Taxation of Service Income: BUT NC vs. DJP and the Construction Services Dispute

The taxation system for service income in Indonesia frequently triggers disputes, particularly when there is an intersection between Article 23 Income Tax (Non-Final) on installation/equipment services and Article 4 paragraph (2) Final Income Tax on Construction Services. The case of BUT NC versus the Director General of Taxes (DJP) highlights this crucial dilemma within the context of telecommunication infrastructure projects. The core dispute revolves around the negative correction of the Taxable Base (DPP) for Article 23 Income Tax for January 2020, where the DJP reclassified the payment for submarine cable installation (Submarine Cable Services) to a subcontractor as Construction Services, subject to Final Income Tax. This divergence stems from interpreting the definition of "Construction Work" and the legal weight given to the latest Construction Law versus derivative tax regulations.

The Core Conflict: Equipment Installation vs. Construction Definition

The core conflict is divided into two distinct argumentative positions. On one side, BUT NC argues that the service provided—the installation of submarine telecommunication cables—is essentially an equipment installation service, which is explicitly covered by Article 23 Income Tax as per Minister of Finance Regulation (PMK) Number 141/PMK.03/2015. Furthermore, BUT NC employed the lex posterior principle, referencing Law Number 2 of 2017 on Construction Services (UU 2/2017), which defines construction solely as activities resulting in "a building," asserting that submarine cables do not meet the criteria of a permanent structure. Conversely, the DJP insisted that the payment was subject to Final Income Tax. Their argument was supported by the contract scope, which included the element of "construction," and the formal evidence of a Large Qualification (B2) Business Entity Certificate (SBU) held by the subcontractor, PT ITI, for telecommunication network construction implementation services. The DJP also cited the Minister of Public Works Regulation, which specifically includes submarine cable laying services in the construction classification (code EL005).

Resolution and the Weight of Sectoral Regulations

In its resolution, the Tax Court, by a majority vote, rejected BUT NC's appeal. The judicial opinion gave high weight to sectoral regulation and the formality of the service provider's SBU. The Court held that the Ministry of Public Works and Housing (PUPR) has the authority to define construction criteria, and referencing the PUPR Minister Regulation, submarine cable laying services are classified as construction. Since PT ITI possessed a Large Qualification SBU for the relevant service type, the payment received by PT ITI was legally subject to Final Construction Income Tax (3% rate according to PP 51/2008). This decision effectively superseded BUT NC's lex posterior argument based on UU 2/2017.

Implications for Taxpayers and Formal Due Diligence

An analysis of this decision indicates that in disputes involving the overlap between installation and construction services, the formal aspect, such as the service provider's possession of a Construction Business Entity Certificate (SBU), becomes the key determinant for the Tax Court, even when a potential conflict with the newer Construction Law exists. The implication for Withholding Taxpayers is the need for extremely rigorous due diligence on the formal qualifications of every vendor. Taxpayers must look beyond the physical substance of the work and adhere to PUPR sectoral classification and contractor certification status. This ruling sets a precedent that SBU formality can shift the Income Tax treatment from Non-Final (Article 23) to Final (Construction Tax).

Conclusion: The Dominant Role of SBU in Withholding Strategy

In conclusion, this case serves as a vital reminder for companies, particularly in the telecommunication infrastructure sector, that technical sectoral regulations (PUPR) play a dominant role in classifying the type of service, which subsequently determines the Income Tax treatment. A secure withholding strategy must be grounded in the vendor's SBU. The dispute also reflects an urgent need for the harmonization of tax regulations, especially PP 51/2008, with the latest Construction Services Law to minimize potential reclassification disputes.
