The dispute arose when the Respondent issued a positive correction to the VAT Tax Base (DPP) for the February 2017 tax period against PT LVI using cash flow testing techniques. The Respondent identified incoming funds in the bank account that were not reported as business turnover in the VAT Return. The tax authorities argued that any incoming cash balance whose source cannot be thoroughly proven constitutes taxable income. However, PT LVI asserted that the funds were reimbursements from customers due to technical failures in the e-Faktur system that prevented the issuance of credit notes, thereby creating an undue VAT burden.
The core of this legal conflict lies in proving the nature of the incoming funds and applying the substance over form principle. The Respondent insisted on using an annual pro-rata method to determine monthly tax bases, an approach considered administratively weak as it fails to consider the specific timing of tax liability. On the other hand, PT LVI successfully demonstrated that the e-Faktur system anomaly, marked by "Tax Invoice Not Found" notifications, was a technical fact acknowledged by the tax authorities' own officers during the trial. The incoming funds were purely compensation for losses resulting from the system's inability to process electronic returns.
The Tax Court Judges, in their consideration, stated that cash flow testing must not ignore material facts on the ground. The Panel assessed that general ledger evidence and court testimony cumulatively confirmed the funds as reimbursement rather than the delivery of Taxable Goods or Services. The final verdict granted the appeal in its entirety, emphasizing that cash flow equalization methods must be supported by concrete transaction evidence and cannot be performed unilaterally through pro-rata distribution if month-specific evidence is available.
The implications of this decision serve as an important precedent for Taxpayers facing systemic hurdles in tax information technology infrastructure. This ruling reaffirms that e-Faktur system failures should not jeopardize the constitutional rights of Taxpayers. Companies must ensure that correspondence documentation regarding system errors and reimbursement agreements are well-maintained as mitigation evidence for future audits.
