The tax dispute between PT MMS and the Directorate General of Taxes (DGT) highlights the utilization of third-party data as the sole basis for Value Added Tax (VAT) corrections. The DGT corrected the Taxable Base (DPP) for VAT on self-collected deliveries for the July 2020 tax period by IDR 182,202,959, based on Article 23 Income Tax withholding slips and Input Tax Invoices from PT IT. The primary polemic revolves around whether unilateral recording by a counterparty automatically constitutes material evidence of a taxable delivery for the taxpayer under audit.
The core of the conflict in this case is divided into two distinct evidentiary aspects. First, a correction of IDR 12,722,727 derived from Article 23 withholding slips. The DGT insisted that the reporting by PT IT in its Tax Return served as authentic evidence of a transaction, whereas PT MMS denied it, claiming they never received an invoice or any cash inflow. Second, a correction of IDR 169,480,231 based on Input Tax Invoices allegedly issued by PT IT. PT MMS emphasized that they never credited those invoices and there was no physical evidence of goods or services delivered to support them.
The Tax Court Judges provided different resolutions for these two items. Regarding the Article 23 withholding correction, the Court upheld the DGT's correction because official confirmations from the counterparty's Tax Office and a direct response from PT IT stated the transaction was "Present." The Court argued that reporting in a Tax Return carries significant legal responsibility. However, for the tax invoice correction of IDR 169,480,231, the Court overturned the DGT's decision. This was because the DGT failed to prove the existence of the transaction through cash flow and commodity flow testing, as mandated by KEP-754/PJ./2001, coupled with data uncertainty from PT IT itself.
Analysis of this decision indicates that although third-party data (confirmation) holds a strong position, it is not absolute if not supported by other material corroborating evidence. The implications of this ruling reinforce that tax authorities must conduct in-depth testing of physical and financial flows before determining tax liabilities, especially when a taxpayer consistently denies the transaction's existence. This decision serves as an important precedent for taxpayers to proactively reconcile counterparty data to mitigate the risk of unilateral tax assessments.
