Lawsuit Won! PT KAL Successfully Cancelled Billions in Tax Collection Letters as DGT Violated PPh 25 Installment Procedures

PT KAL Lawsuit: Legal Flaws in Issuing STP Without a Formal Installment Determination Decision

This dispute focuses on the validity of the issuance of a Tax Collection Letter (STP) for underpayment of Income Tax Article 25 installments, carried out unilaterally by the Defendant without following the assessment procedures stipulated in tax regulations. PT KAL, as the Plaintiff, faced a tax bill of IDR 3.2 billion for the October 2022 Tax Period, even though the company had reported a fiscal loss in the previous Annual Tax Return, resulting in zero installments for the current year. The core issue lies in whether the Defendant could directly issue an STP based on a unilateral recalculation without first issuing a Decision on the Determination of Tax Installment Amount in accordance with Article 25 paragraph (6) of the Income Tax Law juncto KEP-537/PJ/2000.

The Conflict: Self-Assessment vs. Unilateral Official Assessment

The conflict began when the Defendant recalculated PT KAL's loss compensation and concluded that there was an obligation for PPh 25 installments of IDR 3.1 billion per month. On the other hand, the Plaintiff emphasized that according to the self-assessment principle, the valid installment amount is the one stated in the Corporate Income Tax Return as long as there is no official assessment changing it. The Plaintiff argued that the Defendant's action of directly issuing an STP without a formal determination decision was an abuse of authority and violated the taxpayer's procedural rights.

Judicial Consideration: Administrative Formality as a Prerequisite for Collection

The Board of Judges, in its legal considerations, emphasized that although the Defendant has the official assessment authority to change the amount of PPh 25 installments if there is remaining loss compensation, this authority is not automatic. Such authority must be manifested in a legal product in the form of a Decision on the Determination of Income Tax Article 25 Installment Amount notified to the Taxpayer. Without such a decision letter, the installment amount calculated by the Taxpayer in the tax return (which was Nil) remains considered legally correct and binding. Therefore, the issuance of the STP based on an installment that had not been officially determined was declared legally flawed.

Implications: Limits of Discretion in Changing Tax Obligations

This legal resolution provides significant implications for tax practice, where the discretionary power of the tax authority must remain subject to the principles of legal certainty and administrative formalities. This ruling confirms that appeal letters or internal research cannot replace the function of an official decision letter in changing a taxpayer's self-assessment obligation. For taxpayers, PT KAL's victory serves as a strong precedent for challenging administrative actions by tax authorities that ignore formal procedural stages in determining current tax burdens.

In conclusion, the Board of Judges canceled the STP because the Defendant was proven not to have carried out the formal installment determination procedure. This case serves as a reminder for tax authorities to maintain administrative order and for taxpayers to be more observant of procedural aspects in every legal product issued by the tax authority.
