Victory at the Tax Court: Why Tax Auditor's Extrapolation Methods Can Be Overturned by Judges?

VAT Base Correction and the Extrapolation Dispute

The tax dispute involving PT TTI originated from the Respondent's correction of the VAT Base for the January 2019 Tax Period amounting to IDR 1,246,368,106.00 using an extrapolation method. The Respondent based the correction on findings of delivery note differences deemed as unreported deliveries, yet this step was taken without the support of concrete flow of goods and flow of money evidence for each corrected transaction.

The Core Conflict of Extrapolation Validity

The core of the conflict in this case centers on the validity of the extrapolation method used by the tax authority in determining the actual delivery value. The Respondent argued that the Taxpayer's inability to prove all delivery documents during the audit granted the auditor authority to extrapolate the potential annual sales. Conversely, PT TTI firmly denied this, stating that the discrepancy was merely a system administrative error or product samples that are not VAT objects, and emphasized that extrapolation lacks a strong legal basis in the VAT Law for determining taxes due.

Legal Opinion of the Tax Court Judges

The Tax Court Judges, in their resolution, provided a crucial legal opinion for Taxpayer certainty. The Judges emphasized that in the context of contentious jurisdiction, the burden of proof for the validity of the correction lies with the Respondent. Since the Respondent was unable to detail each corrected delivery unit through flow of goods and money tests, the extrapolated figures were considered unilateral estimates that do not reflect the actual situation as mandated by Article 13 paragraph (5) of the VAT Law.

The Implication and Legal Risks of the Decision

The implication of this decision reaffirms that extrapolation methods in VAT audits carry a high legal risk of being overturned if not accompanied by detailed material transaction evidence. For Taxpayers, this decision serves as an important reminder of the importance of synchronizing internal delivery documents with Tax Invoice reporting. Legally, the Panel of Judges has maintained the integrity of formal and material law by not justifying tax assessments based solely on mathematical assumptions without physical evidence of delivery.

In Conclusion

In conclusion, the Panel of Judges granted PT TTI's entire appeal and canceled the Respondent's entire correction. This proves that the strength of material evidence remains the commander in the resolution of tax disputes in Indonesia.
