PT Tembaga Mulia Semanan Tbk Successfully Overturns VAT Correction Based on Vague Extrapolation Methods

Tax Dispute: VAT Extrapolation Method and Export Evidence Validity

The tax authority imposed a VAT Tax Base (DPP) correction of IDR 197,957,713.00 using an extrapolation method during a re-examination, sparking a dispute over material substance. The dispute centers on the legality of using sales data extrapolation and the evidentiary weight of Export Declaration (PEB) documents as primary evidence for 0% rated deliveries.

Core Conflict: Extrapolation Assumptions vs. Tangible Export Data

The core conflict arose when the Respondent applied extrapolated findings to the December 2012 Tax Period, assuming unreported sales. Conversely, the Taxpayer strongly rebutted this, arguing that all deliveries were exports supported by valid PEB documents, cash flow evidence, and consistent accounting records, thus rendering the extrapolation method legally and materially groundless.

Judicial Consideration: Failure to Meet Evidentiary Standards

The Board of Judges, in its consideration, stated that the Respondent failed to provide detailed transaction data or concrete evidence to support the extrapolation figures. On the other hand, the Taxpayer successfully demonstrated data consistency between export documents and tax reporting. Consequently, the Board overturned the entire correction, citing a failure to meet the tax law's evidentiary standards requiring tangible material proof.

Analysis and Implications: Defense Against Arbitrary Corrections

This decision emphasizes that extrapolation methods cannot be arbitrarily used as a basis for correction without verifiable transaction details. For Taxpayers, this victory highlights the critical importance of maintaining formal documents like PEB and synchronized cash flow evidence as a primary defense against re-examination corrections.
