The Director General of Taxes (Respondent) issued a correction to the Base for Tax Calculation (DPP) of Article 23 Income Tax for the December 2020 Tax Period amounting to 1,550,055,093 IDR through a cost equalization method found in the General Ledger for the entire year. The tax authority's move to charge the accumulated findings from January to December into a single tax period (December) became the central point of the dispute, considering that the January to November Tax Periods had previously been settled through Nil Tax Assessment Letters (SKPN). PT CPN (Appellant) emphasized that this action violated the principle of legal certainty and formal tax procedures which prioritize the separation of obligations per tax period.
The core of the conflict began when the Respondent considered the Appellant uncooperative for not submitting a response to the SPHP and failing to attend the Final Discussion (Closing Conference). Consequently, the Respondent attributed all potential taxes from 17 expense accounts—including demurrage costs, honorariums already subjected to Article 21 Income Tax, and transactions already reported at branch tax offices (KPP)—into the December Period. The Appellant countered with the argument that formally, the Tax Assessment Letter (SKPKB) was defective because it combined tax objects whose periods were already legally binding via SKPN. Materially, the Appellant presented evidence that these costs were not Article 23 Income Tax objects, such as Import Duties paid to the state and transactions utilizing the Final Income Tax scheme under PP 23/2018.
In its legal consideration, the Board of Judges stated that the Respondent's action of pulling an entire year's worth of corrections into the December Period was legally unjustifiable. The Judges referred to Article 2A of the KUP Law, which stipulates that tax obligations begin when subjective and objective requirements are met within a specific tax period. Such "blanket" charging was deemed to create administrative irregularity and violate the principles of fairness. Furthermore, materially, the Board found that the Appellant successfully proved the substance of each cost with competent documents, while the Respondent was proven negligent in conducting the equalization by ignoring tax reporting data from the Appellant's branches.
The implication of this decision confirms that formal procedures in issuing tax assessment letters are mandatory and cannot be disregarded simply because a Taxpayer is deemed uncooperative during an audit. PT CPN's total victory provides a vital lesson for businesses to consistently perform reconciliations between accounting data and reporting at every location (branch) and to maintain the validity of third-party withholding slips. This decision serves as a strong precedent that cost equalization must not be carried out haphazardly without considering the periodicity of tax periods and the status of previously issued tax assessments.
