Disputes regarding Article 23 Income Tax withholding frequently stem from interpretative disagreements over the Tax Base (DPP) for service transactions integrated with material procurement. In the legal case of PT PPT, the Respondent issued a significant correction to the Article 23 Income Tax Base for the January 2020 tax period, totaling IDR 387,026,739. This action was based on bank account expense equalization findings.

This legal conflict intensified when the Petitioner provided substantive proof that the separation of service and material values had been explicitly performed from the outset in every invoice and tax invoice issued by the vendor. The Petitioner emphasized that the materials used originated from the vendor's own inventory (stock). Legally, it was impossible for the Petitioner to attach third-party invoices because those transactions were an internal matter of the vendor.

The Tax Court's Board of Judges, in their legal consideration, rejected the Respondent's rigid approach of only recognizing value separation through third-party invoices. The Board opined that primary billing documents (invoices) and tax invoices that clearly list transaction components constitute valid and sufficient evidence under the law. This ruling confirms that Article 23 Income Tax withholding is only mandatory on the pure service value (net).
The ruling strengthens protection for Taxpayers against assumptive equalization corrections. Strategically, Taxpayers must ensure that every cooperation contract and vendor invoice includes a detailed value separation clause. The conclusion of this case is that documentation accuracy at the primary level (invoices and tax invoices) is the most crucial legal defense instrument in winning tax disputes related to withholding and collection objects.
