Why the DGT's Cash Flow Tests Frequently Lead to Disputes in the Tax Court? A Case Study of PT SB

Taxpayer compliance examination procedures via gross turnover adjustments, particularly those initiated by the Director General of Taxes (DGT) through cash flow test mechanisms and the reconciliation of Output VAT with Corporate Income Tax (CIT) revenues, frequently serve as a core point of contention in CIT disputes.

In the case study of PT SB (Decision Number PUT-015762.15/2020/PP/M.IVB Year 2025), the Tax Court Panel of Judges ruled to partially grant the tax appeal. This outcome serves as a strong indication that adjustment methodologies relying heavily on cash movement assumptions are not always absolute, and a Taxpayer's verification of non-revenue items can be legally accepted.

The core conflict within this dispute centered upon the interpretation and application of Article 4 paragraph (1) of the Income Tax Law.

The DGT, acting as the Respondent, utilized bank and cash flow testing results to identify credit mutations, which were subsequently assumed to represent unrecorded current-year sales turnover. This operational assumption arose due to a positive variance between the turnover declared by the Taxpayer and the cash inflows recorded in bank accounts, alongside discrepancies detected through Output VAT reconciliations. From the DGT's perspective, these discrepancies constituted a robust indication of additional economic capability that the Taxpayer failed to declare.

Conversely, PT SB, acting as the Appellant, forcefully countered these assumptions by advancing structured accounting arguments.

The Appellant's primary line of argument established that not all cash or bank inflows can be legally categorized as taxable income. They successfully demonstrated that a significant portion of the adjusted variance constituted non-revenue transactions, such as cash collection from accounts receivable that had already been formally recognized as taxable revenue in previous fiscal periods, or bank inflows originating from loan funds, which legally do not qualify as objects of income tax. This evidentiary defense was heavily anchored by a detailed Reconciliation Working Paper explaining the timing differences between VAT recognition (at the time of delivery) and Income Tax recognition (under the Taxpayer's accrual accounting method).

Ultimately, the Panel of Judges adopted a balanced approach by granting the tax appeal in part.

The Court's legal opinion clarified that the burden of proof does not rest solely on the Respondent to verify compliance, but equally requires the Appellant to present a robust counter-evidentiary defense. Consequently, the Respondent's adjustments that lacked adequate explanatory backing or were successfully refuted by authentic source documents from the Appellant (such as formal loan agreements or prior-year sales invoices) were overturned. Conversely, corrections that the Taxpayer failed to adequately reconcile were legally sustained.
