Not Revenue, But Loans! How PT GL Won a Billions-Rupiah Cash Flow Dispute in Tax Court

Legal Dispute Analysis: Cash Flow Testing vs. Intercompany Loan Substance

Tax authorities frequently employ indirect methods such as cash flow testing to determine a taxpayer's business turnover. In the case of PT GL, the Respondent made a positive correction to Business Turnover amounting to IDR 373.36 billion based on credit mutations in bank statements, which were deemed unreported sales.

The Conflict: Credit Mutations vs. Intercompany Loans

The core conflict arose when the DGT assumed every incoming fund in the bank statement was an unreported sale:

• Respondent's Position: Argued that large-scale credit mutations without initial explanation were concealed turnover.
• Petitioner's Defense (PT GL): Materially proved that the fund flows were not an increase in economic capability, but rather intercompany loan transactions between affiliates and internal overbookings.

Judicial Review: Consistent and Relevant Supporting Evidence

The Board of Judges emphasized the availability of an airtight audit trail presented by the taxpayer:

1. Documentary Strength: PT GL presented a comprehensive loan list, accounts receivable/payable ledgers, and bank transfer slips consistently showing the nature of the loans.
2. Failure to Prove Delivery: The Board opined that the Respondent could not prove any delivery of goods or services underlying the fund flow as turnover.
3. Verdict: The Board canceled the entire turnover correction as PT GL's evidence was considered more convincing and successfully refuted the tax authority's assumptions.

Implications: Prohibition of Mechanistic Cash Flow Testing

This decision reaffirms the limitations of tax authorities in using indirect testing methods:

• Substance over Form: Cash flow testing should not be performed mechanistically without considering the actual substance of the transaction behind the numbers.
• Defensive Strategy: For taxpayers, the integrity of general ledgers and the documentation of intercompany loan agreements are the primary protections against cash flow audits.

Conclusion: PT GL's victory demonstrates that transparency in fund flows, supported by neat accounting records, can nullify corrections worth hundreds of billions. Cash flow testing must yield to material evidence and actual business logic.
