Winning in Tax Court: How PT TTI Rebutted DGT’s Accounts Receivable Extrapolation Correction

VAT Base Correction and the Accounts Receivable Flow Test

Tax authorities frequently employ the accounts receivable flow test to identify unreported taxable supplies, yet methodological weaknesses lacking physical inventory evidence can lead to a taxpayer's victory in court. The dispute between PT TTI and the Directorate General of Taxes (DGT) regarding a VAT base correction for the April 2019 period amounting to IDR 1.24 billion serves as a critical case study on the limits of using extrapolation methods in tax audits. The conflict originated from audit findings suggesting a discrepancy between reported sales and the results of a receivable flow reconciliation.

The Core Conflict of Extrapolation Methods

The Respondent (DGT) maintained the correction, arguing that the Petitioner failed to provide data aligning the receivable flow with the turnover reported in the tax returns. The auditors utilized extrapolation techniques to conclude that certain taxable supplies remained uncollected. Conversely, PT TTI firmly rebutted this by demonstrating fundamental errors in the auditor's determination of beginning and ending receivable balances. The Petitioner argued that the discrepancy was merely a matter of cut-off timing in accounting records rather than hidden taxable objects.

Legal Consideration and Judicial Conviction by the Board of Judges

The Board of Judges, in their legal consideration, emphasized that judicial conviction must be based on at least two valid pieces of evidence as per Article 76 of the Tax Court Law. The judges viewed the Respondent's receivable flow test as an indirect method unsupported by physical goods flow evidence confirming the actual delivery of Taxable Goods. In contrast, the Petitioner successfully presented solid documentary evidence, including general ledgers, invoices, and bank statements, validating their receivable flow. The Board's decision to grant the appeal in its entirety reinforces the principle that tax corrections cannot rely solely on mathematical assumptions without tangible transaction evidence. This implies that taxpayers must strengthen their receivable reconciliation documentation when facing audits involving indirect testing methods.
