VAT Base (DPP in Indonesian) corrections based solely on account receivable tests from bank statements without evidence of goods or services delivery have lost their legal legitimacy. In the dispute between PT BNP and the Directorate General of Taxes (DJP), the tax authority performed an ex-officio assessment by assuming every cash inflow in the bank account was taxable income subject to VAT. The core issue arose when the DJP failed to detail the types of transactions occurring, violating the principle of materiality.
The DJP's argument centered on PT BNP's failure to provide accounting documents during the audit, making indirect methods the only way to determine tax potential. The DJP equalized findings from the Corporate Income Tax audit and applied them proportionally to VAT periods. However, PT BNP firmly stated that cash inflows do not always reflect the delivery of Taxable Goods or Services, which is a mandatory requirement for VAT under Article 4 paragraph (1) of the Indonesian VAT Law (UU PPN).
The Panel of Judges provided a fundamental and technical resolution. The Judges stated that "Business Turnover" in the context of Income Tax is substantively different from "Delivery" in VAT. Without details on what was delivered, to whom, and when, bank account inflows cannot be forced as a basis for VAT. The DJP's failure to prove transaction details meant the correction was not based on sufficient competent evidence.
This decision reaffirms that the burden of proof regarding the existence of a tax object remains with the DJP, even if the Taxpayer is deemed uncooperative. For businesses, this ruling provides legal protection against "assumptive taxation" often used by auditors through equalization methods. In conclusion, PT BNP's victory reinforces the supremacy of material evidence. Taxpayers are advised to maintain the integrity of cash flow supporting documents to explain every account mutation, ensuring legal certainty against ex-officio assessments.
