The Nullification of Non-Service Component Testing for WHT Article 23 Tax Base Correction: An Examination of the Substance Over Form Principle

The material and substantive evidence in the equalization dispute, specifically concerning Income Tax Article 23 (WHT Article 23), arose from the case of PT AI. In its findings, the Directorate General of Taxes (DGT) based its correction solely on the mathematical difference between the expense account in PT AI’s General Ledger (GL) and the Declared Tax Base (DPP) value reported in the WHT Article 23 Periodic Tax Return (SPT Masa) for the September 2016 tax period. The DGT did this without considering the complexities of cost recognition and the timing of tax accrual. This gave PT AI an opportunity to challenge the tax authority’s inability to specifically prove the service transactions that had not been subject to withholding, ultimately leading to the nullification of the Underpaid Tax Assessment Letter (SKPKB) for WHT Article 23 amounting to Rp9,022,733,270.00.

This dispute centered on the differing interpretations of the "gross amount" for WHT Article 23 and the issue of burden of proof. The DGT adhered to Article 1 paragraph (5) of the Minister of Finance Regulation Number 141/PMK.03/2015, which granted the DGT the right to enforce withholding on the full gross amount if PT AI failed to clearly segregate non-service components—such as cost reimbursement or material purchases—from the service fees. The DGT maintained its correction, arguing that PT AI had failed to fulfill the request for detailed evidence during the objection stage.

Nevertheless, PT AI presented a structured defense by outlining three key factors that caused the discrepancy, none of which were components subject to WHT Article 23: (1) Non-object components, such as purchases of goods and reimbursements, which were initially mixed in the service accounts but were successfully segregated and proven by PT AI during the hearing. (2) Timing differences between the recording of expenses in the GL and the time the WHT Article 23 became due; the tax was proven to have been withheld and reported in the subsequent tax period. (3) Foreign exchange differences (forex difference) used in bookkeeping (BI exchange rate) versus the rate used in the tax audit calculation (Minister of Finance Decree rate at year-end).

The material arguments articulated by PT AI were considered and explicitly approved by the Tax Court Panel of Judges in the issued ruling. The Panel proceeded to cancel the entire WHT Article 23 Declared Tax Base (DPP) correction imposed by the DGT. This cancellation was based on the Panel’s assessment that a correction relying solely on an equalization difference, without supporting evidence specific to each transaction, disregarded the substantive facts presented by PT AI. By accepting PT AI's systematic counter-reconciliation, the Panel concluded that PT AI had successfully discharged the reverse burden of proof.

This ruling underscores the critical importance for Taxpayers to maintain highly detailed accounting systems and documentation. This includes clear segregation between service and non-service costs (such as materials or reimbursement), as well as accurate recording of the timing of WHT Article 23 withholding, in order to prevent arbitrary corrections based purely on assumption.
