The implementation of Article 26A paragraph (4) of Law Number 6 of 1983 concerning General Provisions and Tax Procedures (KUP Law) has become a critical issue challenging the principle of searching for substantial truth in Indonesian tax disputes. The PPh Article 21 (Withholding Tax) dispute between PT TBSM and the Directorate General of Taxes (DJP) at the Tax Court level clearly highlights how failure to comply with formal documentation requirements can lead to the rejection of an appeal, even if the PT TBSM claims to hold the substantial truth. This case resolves a dispute over a PPh Article 21 object correction of Rp. 623,706,801.00 which resulted in an underpayment tax assessment (SKPKB) that must be fully paid.
The conflict originated during the tax audit where the DJP performed the correction using the equalization technique between the total wage costs expensed by PT TBSM in its income statement and the PPh Article 21 object reported in the PPh 21 periodic Tax Return. A material difference was found that could not be substantiated with detailed documentation during the audit. The DJP argued that PT TBSM's failure to provide the requested books, records, and/or documents in detail during the audit, as mandated by KUP Law Article 26A paragraph (4), provides a legal basis for DJP to reject considering new evidence, such as the wage recapitulation, that was only submitted during the objection stage. Conversely, PT TBSM insisted that the correction was not due PPh 21 because the contract worker wages were individually below the Non-Taxable Income (PTKP) threshold, and requested the Panel of Judges to use Articles 69, 76, and 78 of the Tax Court Law to accept the evidence in pursuit of substantial truth.
The Tax Court Panel of Judges explicitly reinforced the DJP's position, stating that the DJP's action to reject considering new evidence at the objection stage was appropriate and compliant with KUP Law Article 26A paragraph (4). The Panel considered that this norm aims to encourage Taxpayers to be cooperative and formally compliant at the audit stage. Consequently, the Panel also ruled not to consider the same evidence newly submitted during the appeal hearing. Thus, the Panel concluded that without any admissible evidence to substantiate the PPh Article 21 equalization difference, the DJP's correction was legally justified, and decided to reject PT TBSM's appeal.
This decision sends a powerful message to the Taxpayer community and tax law practitioners: procedural compliance at the audit stage is the primary prerequisite (procedural law) for advancing a substantial defense (substantive law) at the litigation stage. The implication of this decision for general tax practice is that Taxpayers must be proactive and ensure that all documents requested by the Tax Auditor, especially those related to equalized costs, are submitted completely and in detail. Taxpayers' failure in the PPh Article 21 documentation administration, particularly concerning contract workers below PTKP, carries a high risk of total correction if the formal aspect of evidence submission is not met, regardless of the substantive tax truth.
This case illustrates that the pursuit of substantial truth in the Tax Court can be obstructed by violations of formal compliance during the audit. Taxpayers must strengthen their tax risk management strategy by ensuring that documentation systems, especially for contract labor costs, are always ready, complete, and fully submitted upon audit, to avoid the rejection of evidence that ultimately leads to the rejection of the tax appeal.
