Warning! Internal Documents Alone Aren’t Strong Enough to Fight Million-Rupiah Tax Corrections.

Tax Dispute: Cost of Goods Sold Correction, Competent Evidence Standards, and Tin Ore Purchases for CV BAM

The Directorate General of Taxes (DGT) performed a significant correction on the Cost of Goods Sold regarding tin ore purchases worth IDR 40.6 billion, as they were deemed unsupported by competent evidence under Article 6, Paragraph (1) of the Income Tax Law. Upon audit, it was discovered that the supporting documents consisted only of internal cash out vouchers and receipts lacking clear seller identities, and were not accompanied by valid third-party invoices or tax invoices.

Core Conflict: Internal Documentation vs. Formal Third-Party Proof

The core of the conflict lies in the differing standards of proof between the Taxpayer and the tax authorities. The Petitioner (CV BAM) argued that such internal documents are customary in the business practice of collecting tin ore from local communities. Conversely, the Respondent asserted that without clear counterparty identities and valid physical evidence, these costs cannot be categorized as deductible expenses for obtaining, collecting, and maintaining income. Furthermore, the Respondent highlighted that CV BAM’s primary contract with PT Timah Tbk was for transportation services, not goods trading, rendering the purchase costs substantively irrelevant.

Judicial Resolution: Matching Cost Against Revenue and Business Logic

In its deliberation, the Board of Judges agreed with the Respondent. The Judges emphasized the "matching cost against revenue" principle, where claimed expenses must directly relate to reported income. Given that the work order (SPK) was for transporting residual processing materials, massive tin ore purchases were deemed business-illogical. Additionally, large cash transactions without clear seller identities were considered a violation of the arm’s length principle and fair business practices.

Implications: Alignment of Documentary Formality and Economic Substance

The analysis of this decision shows that documentary formality and economic substance must align. The DGT's victory in this case reaffirms that taxpayers cannot rely solely on self-generated internal documents for material transactions. The implication for other taxpayers is the necessity of ensuring every expense is supported by verifiable external evidence.

In conclusion, the Board of Judges rejected the appeal because the Petitioner failed to provide convincing and competent evidence during the trial. This ruling serves as a stark reminder of the importance of orderly tax administration and compliance with the substance of registered business activities.
