The tax dispute between PT MMS and the Directorate General of Taxation (DGT) highlights the necessity of material evidence in the Value Added Tax (VAT) self-assessment system, specifically regarding corrections to the Tax Base (DPP) derived from third-party data. The Respondent applied a positive correction to the VAT Tax Base for the October 2020 period amounting to Rp2,160,628,827.00, utilizing external confirmation from the counterparty, PT Indosat Tbk, which included Article 23 Income Tax withholding evidence and Input Tax Invoices converted via a gross-up method.
The core conflict arose when the Respondent maintained that the counterparty's expense reporting served as authentic proof of service delivery by PT MMS for which VAT had not been collected. Conversely, PT MMS categorically denied the existence of these transactions, arguing that the company never issued invoices or Output Tax Invoices to the counterparty. PT MMS emphasized that the absence of cash inflows to the corporate bank accounts and the lack of delivery notes (goods flow) proved that the third-party data did not represent actual economic reality.
In its legal considerations, the Board of Judges adopted a split stance on the two correction components. Regarding the correction based on Article 23 withholding tax, the Board upheld the correction as it was deemed strong evidence of income receipt. However, regarding the correction based on the counterparty's Input Tax Invoices totaling Rp1,543,036,513.00, the Board overturned the decision. The Board asserted that the mere existence of a Tax Invoice, without supporting evidence of valid cash flow and goods flow, cannot serve as a basis for determining the delivery of taxable goods or services.
The implications of this decision reaffirm the principle that material truth in tax law supersedes the formal truth of administrative systems. For taxpayers, the PT MMS case serves as a crucial lesson to consistently align internal data with third-party reporting and strengthen reconciliation documentation. This ruling also serves as a warning to tax authorities that using gross-up methods and external data without substantive verification of cash flows often fails to withstand judicial scrutiny.
In conclusion, although the Respondent has the authority to make corrections based on third-party data, the burden of proof regarding the occurrence of delivery must still meet the "flow of goods and flow of money" standard. PT MMS's partial victory proves that consistent accounting documentation can invalidate presumptive corrections.
