Income Tax Article 26 and DTAA: When Is an Underpaid Tax Assessment Notice (SKPKB) Canceled? Insights from the PT CI Court Decision

The implementation of Income Tax Article 26 (PPh Pasal 26), which governs the withholding tax on Non-Resident Taxpayers' (WPLN) income, often results in disputes, especially when taxing rights are contested against the provisions of a Double Taxation Agreement (DTA). The case study from Tax Court Decision Number PUT-005055.13/2024/PP/M.XIIIB Tahun 2025 involving PT CI illustrates the complexity of reconciling domestic and international tax regulations. The central dispute revolves around the PPh Article 26 correction for the September 2021 tax period imposed by the Directorate General of Taxes (DGT), which was based on the rejection of DTA benefits due to issues of formality and substance.

The core conflict in this case is the contention between the Petitioner's claim that the income paid to the WPLN constitutes Business Profits and should not be taxable in Indonesia (as the WPLN does not have a Permanent Establishment or PE), versus the DGT's argument that the domestic rate of 20% should apply. The DGT insisted on the domestic rate because the Petitioner was deemed to have failed to meet the DTA's administrative requirements, particularly regarding the validity of the DGT Form (Certificate of Domicile). The DGT argued that formal defects in the DGT Form (such as failure to fill in the beneficial owner section or late submission) automatically nullify the WPLN's right to DTA benefits, thus reverting the taxing right to the domestic PPh Law.

The Tax Court Judges, in their legal consideration, adopted a middle ground by testing each transaction separately. In principle, the Panel acknowledged the Petitioner's right to DTA benefits, but this was made strictly conditional on meeting the formal DGT requirements and proving the substance of the income. The Judges examined the evidence presented by the Petitioner. Consequently, a portion of the PPh Article 26 correction was nullified (Partially Granted) because the Panel concluded that certain DGT Forms were valid and the corresponding transactions genuinely met the criteria for Business Profits under the relevant DTA. Conversely, the remaining corrections were upheld because the DGT's alleged formal deficiencies were considered substantial enough to justify the application of the 20% domestic rate.

The implication of this ruling underscores that in PPh Article 26 disputes, the Taxpayer's success largely depends on maintaining formal compliance with DTA requirements from the outset of the transaction. Minor flaws in the DGT Form can be used as grounds by the tax authority to deny DTA application, forcing the Taxpayer to face the 20% domestic rate. Therefore, Taxpayers must implement strict verification procedures for every DGT Form received. This decision serves as a crucial guideline: PPh Article 26 litigation demands layered proof, encompassing not only the formality of the DGT but also the substantive documentation of the transaction (income classification and proof of no PE).
