Cash Flow Audit Alert! How PT BYG Secured a Win on Affiliate Loans but Lost on Cash Deposit Verification at the Tax Court.

Legal Dispute Analysis: Cash Flow Testing and the Integrity of Internal Records (PT BYG)

The dispute originated when the Respondent made a positive VAT base correction for the January 2016 period amounting to IDR 1,821,875,000 against PT BYG. The basis for the correction was the discovery of credit mutations in bank statements that were not reported as turnover in the VAT returns, assuming these represented consideration for the delivery of Taxable Services.

The Conflict: Affiliate Loans vs. Unexplained Vault Deposits

PT BYG contested this assumption, detailing that the funds consisted of:

• Interest-free loans from affiliates (Lioni Group) to bolster bank liquidity for tender requirements.
• Cash deposits from the office vault.

The Petitioner argued that under Article 18 (4) of the Income Tax Law, special relationships allow for interest-free loans, meaning such mutations are not automatically considered turnover.

Judicial Review: The Material Truth Test

The Board of Judges conducted a Material Truth Test with differing outcomes for the disputed amounts:

1. Validated Loans (Appeal Granted): Regarding the IDR 20,000,000 inflow, the Judges found synchronized cash flow evidence and were convinced the transactions were genuine debts.
2. Vault Deposits (Appeal Denied): Regarding the IDR 1,801,875,000, the Judges ruled that the Petitioner failed to provide authentic evidence, such as daily vault cash books. Without clear source-of-fund documentation, these deposits remained categorized as unreported taxable deliveries.

Implications: The Necessity of Rigid Documentation

The Board's decision to partially grant the appeal offers a crucial lesson: the burden of proof in cash flow disputes relies heavily on the integrity of internal documents. Bank statement mutations must be supported by orderly daily cash records to distinguish between loans, capital injections, or taxable deliveries.

Conclusion: The Board upheld the majority of the cash deposit correction due to the Petitioner's weak internal documentation, highlighting the necessity for rigid cash document management for construction companies facing audits.
