PT HAU's Victory Against Incorrect Tax Assessments Through Article 36 KUP Procedures.

Legal Analysis: PT HAU Lawsuit Against Incorrect Tax Assessment

The Director General of Taxes Decision Number KEP-00066/NKEB/WPJ.16/2025 became the primary object of dispute in a lawsuit filed by PT HAU regarding the rejection of an application for the reduction of an incorrect tax assessment. This dispute originated when the Defendant rejected the Plaintiff's application based on Article 36 paragraph (1) letter b of the KUP Law concerning a Corporate Income Tax Underpayment Assessment (SKPKB) for the 2017 Tax Year, claiming that the research procedure had met formal requirements despite the Plaintiff's contestation of the tax calculation's validity.

Core Conflict and Material Research Obligations

The core of the conflict in this case lies in the differing interpretations of the depth of material research obligations by the tax authorities in responding to a taxpayer's application. The Defendant argued that the rejection decision was based on internal data considered valid, while the Plaintiff emphasized the existence of substantive defects in the original tax assessment calculation that were not carefully considered by the Defendant during the administrative process. The Plaintiff stressed that the taxpayer's right to obtain corrections for incorrect assessments is a statutory mandate that must be executed with the principle of due diligence.

Tax Court Resolution and Burden of Proof

The Tax Court Judges, in their resolution, stated that the function of Article 36 paragraph (1) letter b of the KUP is not merely an administrative formality but a corrective instrument for material inaccuracies. During the trial, the Defendant was found unable to present strong supporting evidence to maintain its original correction. Conversely, the Plaintiff successfully proved that the basis of the calculation in the SKPKB contained clear errors. The judges emphasized that the burden of proof regarding the correctness of an assessment lies with the tax authorities when its legal basis is materially tested in a lawsuit hearing.

Legal Certainty and Precedents

The implication of this decision confirms that any administrative decision rejecting a taxpayer's application for the annulment of an incorrect assessment can be overturned if it is not accompanied by comprehensive legal considerations. This ruling serves as an important precedent for taxpayers to continue striving for substantive justice through lawsuits if administrative applications at the Regional Tax Office level are rejected without adequate material research. Legal certainty in taxation demands the accuracy of fiscal data as the primary basis for tax imposition.

In conclusion, the Panel of Judges granted the Plaintiff's entire lawsuit and annulled the Defendant's decision. This victory proves that legal protection for taxpayers against incorrect assessments is available through solid evidence in court.
