Why DGT's Equalization Corrections Are Void if Formal Procedures Are Violated? 

PT KMP Tax Dispute: Compliance with Tax Procedural Law and the Validity of Consolidated SKPKB

The tax dispute between PT KMP and the Directorate General of Taxes (DGT) highlights the critical importance of compliance with tax procedural law and the principle of due process of law. The Respondent issued an Article 4(2) Income Tax correction for the December 2021 period using tax equalization techniques over a fiscal year, yet consolidated the entire tax potential into a single Underpayment Tax Assessment Notice (SKPKB) for the December period.

Two Dimensions of Conflict: Material Purchases vs Fatal Formal Defect

The core of the conflict in this case involves two dimensions: formal and material. Materially, the DGT argued that mutations in the Assets Under Construction (ADP) account constituted Construction Service objects that had not been withheld. Conversely, PT KMP asserted that the transactions were purely material purchases from hardware stores, involving no provision of services. However, this material debate became secondary upon the discovery of a fatal formal defect: the DGT issued the December SKPKB to accommodate corrections that actually spanned the entire year.

Judicial Evaluation: Adherence to Operational Regulations and Tax Periodization

In its legal considerations, the Board of Judges emphasized that while the KUP Law grants the DGT authority to determine taxes due, the exercise of such authority must adhere to operational regulations, specifically Article 3 paragraph (3) of PMK-183/PMK.03/2015. This regulation mandates that a separate assessment notice must be issued for each tax period if tax potential is identified in different periods. The Board ruled that merging a year’s worth of tax potential into a single year-end tax period violates the principle of legal certainty.

Protection of Taxpayer Rights and Precedents for Equalization Methods

An analysis of this decision shows that the Board of Judges prioritized the protection of taxpayer rights against arbitrary administrative actions. By nullifying the correction on formal grounds, the Board reaffirmed that procedural validity is an absolute prerequisite before material truth is tested. For PT KMP, this ruling provides legal certainty and cancels the entire assessed tax burden. For general tax practice, this case serves as a strong precedent that equalization methods must not disregard the boundaries of tax periodization in the issuance of tax assessments.

In conclusion, PT KMP’s victory demonstrates that the strength of procedural law arguments is often the primary determinant in litigation disputes. Taxpayers must be vigilant in observing the consistency between the audit period and the assessment documents issued by the authorities.
