Disputes over Article 23 Income Tax withholding often stem from the Taxpayer's inability to administratively separate the value of materials and services, as mandated by PMK 141/2015. The case of PT TB demonstrates that arguments unsupported by detailed invoices and contracts will result in the rejection of the appeal by the Tax Court's Board of Judges.
The dispute began when the Respondent performed an equalization between the costs in the Petitioner's Financial Statements and the Article 23 Income Tax Returns. The Respondent identified advertising, promotion, and maintenance expenses that had not been subject to tax withholding, leading to the issuance of an Underpayment Tax Assessment Letter (SKPKB). The Petitioner, PT TB, argued that most of these costs were for the purchase of promotional materials—which are not objects of Article 23 Income Tax—and vehicle maintenance costs that were purely for the purchase of spare parts.
In the courtroom, a sharp conflict of arguments ensued. The Respondent insisted that the total value of these costs constituted objects of Article 23 Income Tax because the Petitioner could not specify the service component within them. Conversely, the Petitioner claimed to have applied Article 4 paragraph (2) Final Income Tax for certain transactions and emphasized that the purchase of goods (spare parts) should not be subject to service withholding tax. However, the Petitioner failed to present supporting documents, such as original invoices clearly separating the price of goods and service fees in accordance with tax regulations.
The Board of Judges, in its legal considerations, emphasized the aspect of evidence pursuant to Article 76 of the Tax Court Law. The Judges opined that although the Petitioner provided narrative explanations, the absence of convincing physical evidence during the trial rendered the rebuttal arguments unacceptable. The Judges ruled that cost charging in bookkeeping not supported by evidence of separate material and service values is automatically deemed as an object of Article 23 Income Tax withholding in its entirety.
This decision has serious implications for Taxpayers in managing documentation for other service transactions. Non-compliance in separating bills between materials and services within a single invoice will result in the entire billing value becoming an object of Article 23 Income Tax. For PT TB, this ruling confirms that legal certainty in formal tax law heavily relies on the strength of the documentary evidence presented before the court.
In conclusion, this dispute provides a valuable lesson: tax administration is not merely a formal obligation but the primary line of defense against fiscal corrections. Without detailed invoices and clear contracts, the argument that a transaction is "merely a purchase of goods" will be easily dismantled by tax authorities and rejected by the court.
