The IDR 20.9 billion positive correction of Cost of Goods Sold (COGS) at PT WB was driven by the Respondent's skepticism regarding the validity of self-generated cash purchase evidence. The tax authority doubted the economic substance of the transactions due to the lack of third-party controls and applied a "matching cost against revenue" method, assuming unreported income from shrimp waste.
The primary conflict centered on compliance with Article 6, Paragraph (1) of the Income Tax Law, where the Respondent argued that internal memos were insufficient to prove expenses for obtaining, collecting, and maintaining income. Conversely, the Taxpayer argued that cash purchases are a necessity in the fishery supply chain in Banjarmasin to maintain fisherman loyalty. Evidence of materiality was reinforced by Domestic Fish Health Certificates from the Quarantine Agency, proving that the volume of goods purchased actually entered the production process.
The Board of Judges provided a progressive legal opinion by recognizing business reality on the ground. The Judges stated that as long as the flow of goods can be physically proven through quarantine authority documents and actual production occurs, the absence of external evidence on purchase memos does not automatically invalidate cost deductibility. The Judges also rejected the assumption of shrimp waste sales because the Respondent failed to prove any actual cash inflows.
The resolution of this case provides legal certainty that testing the materiality of goods flow (substance over form) takes precedence over mere documentary formalities. The implications of this decision emphasize that industry characteristics and local wisdom in transaction patterns must be considered by tax authorities during audits.
In conclusion, PT WB’s victory proves that supporting documentation from other authorities (such as the Quarantine Agency) can serve as very strong key evidence to mitigate risks arising from internal documentation weaknesses in cash transactions.
