The extrapolation method is often a key tool for tax authorities when encountering bookkeeping deemed inadequate during field audits. In the CV GC dispute, the Respondent established a VAT Base correction for the November 2018 period using a technique that generalized daily findings across the entire period. The core conflict focused on the validity of using such indirect methods compared to the real evidence of daily transaction records and bank statements held by the Taxpayer.
The Respondent argued that cash inflows in bank accounts reflected hidden sales, justifying extrapolation under PER-04/PJ/2012. Conversely, the Taxpayer contended that their telecommunications business involves agent balance deposits, where funds are received before the actual delivery of goods, meaning they cannot be immediately recognized as VAT-taxable turnover in the current period.
The Board of Judges, in their resolution, emphasized the principle of material truth. The judges ruled that extrapolation must not be applied arbitrarily if the Taxpayer can provide more detailed supporting evidence for transactions. The evidence test revealed that a significant portion of the Respondent's correction lacked physical proof of goods or services delivered. Consequently, this decision reinforces that cash flow data (cash basis) does not automatically form the basis for VAT unless accompanied by proof of delivery (accrual basis).
In conclusion, CV GC's partial victory offers a crucial lesson for high-cash-turnover businesses to maintain rigorous bank reconciliation systems. Formal compliance is insufficient; the ability to reconstruct the link between cash inflows and delivery status is the primary defense against audits based on indirect methods.
