In the context of self-assessment system enforcement, Tax Court Decision Number PUT-004194.16/2021/PP/M.XVIIIA Tahun 2025 provides a crucial affirmation regarding the validity of using third-party data, specifically the Land and Building Tax Object Notification Letter (SPOP PBB), as the basis for correcting the Value Added Tax Base (DPP PPN). This case involving PT LSS stems from a derivative correction of Corporate Income Tax (PPh Badan) Turnover, where the tax authority (Terbanding) employed an indirect method to establish undeclared potential turnover. The VAT payable was calculated based on the assumed potential production of Fresh Fruit Bunches (TBS) derived from the plantation area according to SPOP, then compared against the turnover reported by the Taxpayer. This dispute highlights the tension between the Taxpayer's formal obligation to cooperate and the Examiner's right to issue a jabatan (ex officio) assessment.

The Core Conflict of the Dispute

The core of this conflict centered on the Appellant's failure to provide primary books, records, and documents, especially the real Production Reports, as a form of cooperation. Relying on Article 28 of the General Provisions and Tax Procedures Law (UU KUP) and examination guidelines, the Tax Authority argued that this failure mandated the use of an indirect method to test the reasonableness of the turnover, which was justified by using SPOP PBB data with a reasonable productivity assumption. The Appellant strongly refuted this, stating that SPOP is merely an estimated potential and not a realization of actual sales that form the basis of VAT.

Legal Considerations and Resolution by the Panel of Judges

However, the Panel of Judges decisively rejected the Appellant's arguments. In its legal consideration, the Panel deemed the Appellant to have failed to substantiate its claims by not presenting real production data nor convincingly demonstrating that actual production was lower than the SPOP estimate. Furthermore, the Panel strengthened the Tax Authority's position by using the fact that the Appellant did not file an appeal against 11 Final PPh Article 4 paragraph (2) Underpayment Tax Assessment Letters (SKPKB) that were based on the exact same turnover correction. This action by the Appellant was interpreted as implicit agreement with the corrected turnover value, which subsequently solidified the legitimacy of the VAT Base correction. This decision clearly emphasizes that in cases of inadequate Taxpayer documentation, the validity of ex officio tax assessment will be upheld.
