Claiming Tax Interest Promises: Why PT LI Failed to Secure Interest Compensation Despite Winning the Appeal?

PT LI Tax Dispute: Right to Interest Compensation and the Non-Retroactive Principle

A tax administrative dispute regarding the right to interest compensation re-emerged in the Tax Court proceedings, involving PT LI against the Directorate General of Taxes. The core conflict centered on the Defendant's refusal to issue a Decision Letter for Interest Compensation (SKPIB) for VAT overpayments arising from a 2022 Appeal Decision. The tax authorities insisted that the application did not meet the criteria of Article 27B paragraph (2) of the Omnibus Law and PMK 18/PMK.03/2021, given the Taxpayer's initial tax return status as Overpayment Carried Forward (Compensation) rather than a refund request, coupled with the absence of any overpayment amount agreed upon during the Final Discussion of Audit Results.

PT LI’s Defense: Lex Prasepito Principle and Old KUP Law Claims

Conversely, PT LI constructed its argument by prioritizing the legal principle of lex prasepito, demanding the application of the old Article 27A of the KUP Law, which provided a fixed rate of 2% per month. The Taxpayer argued that since the original legal event (the issuance of the Tax Assessment Letter/SKPKB) occurred in 2018, the new restrictive rules in the Omnibus Law should not be applied retroactively. They emphasized that a victory at the appeal level should automatically trigger the right to time-value compensation for funds previously held by the state treasury.

Judicial Analysis: Defining the Time of Legal Entitlement

The Board of Judges, in its legal consideration, dissected deeply the timing of the legal entitlement. The Judges opined that the relevant "legal event" for granting interest compensation is not the audit date, but the issuance date of the Appeal Decision that caused the overpayment. Since the Appeal Decision was issued in December 2022, Article 27B of the Omnibus Law must legally be applied. Furthermore, substantively, the judges confirmed that the interest compensation mechanism is only granted for overpayments arising from the payment of assessments under appeal, but it must strictly adhere to the formal requirements in the implementing regulations in effect when the right was born.

Ruling Implications: Differentiating Compensation and Refund Status

The implication of this decision reinforces that Taxpayers must be meticulous in distinguishing between Overpayment Compensation and Refund status in relation to potential future interest compensation. This verdict serves as an important precedent that the non-retroactive principle cannot be used absolutely if a new right emerges after a regulatory change. For practitioners, this case is a reminder that winning the tax substance at the appeal level does not spontaneously guarantee the acquisition of interest compensation if the administrative requirements in the transitional regulations are not cumulatively met.
