Classification of Fund Sources in Unilateral Cash Flow Equalization: PT Berkat Yakin Gemilang Case Study

Cash flow testing is often the tax authorities' ultimate weapon in determining unreported turnover, yet the accuracy of this method depends heavily on the classification of fund sources. In the case of PT BYG, the Respondent (DJP) issued a VAT Base (DPP) correction based on credit mutations in bank statements deemed as taxable services (JKP). The core conflict centered on the Taxpayer's failure to prove that certain inflows were affiliated loans and project guarantee refunds, rather than construction service fees. While the Respondent stood by the assumption of income due to incomplete data during the audit, the Taxpayer provided counter-evidence in court regarding special relationships and operational funding schemes.

The Board of Judges Applies Material Truth Principles to Inter-Company Mutation Entries

The Board of Judges, in their legal consideration, applied the principle of material truth by dissecting each mutation entry. The Judges opined that funds originating from project guarantee liquidations and inter-company loans (with evidence of identical ownership by Mr. Lioni) are substantively not an increase in economic capacity and thus not taxable objects. However, regarding cash deposits claimed to be from the office safe, the Judges rejected the argument due to the absence of valid cash records and a qualified auditor's opinion. This decision reaffirms the necessity of strict financial account separation and rigid cash flow documentation for construction firms to prevent loans from being reclassified as taxable turnover.
