Winning VAT Disputes: Why the Tax Office's Extrapolation Method Failed in Tax Court?

The Tax Authorities Indirect Methods and Data Extrapolation in VAT Returns

The tax authorities often employ indirect methods such as accounts receivable testing and data extrapolation to determine unreported delivery of goods or services in VAT Returns. However, this approach demands high data accuracy and a thorough consideration of timing differences in accounting. The dispute between PT II (Appellant) and the Director General of Taxation (Appellee) in Decision Number PUT-014821.16/2019/PP/M.IVB serves as a significant precedent regarding the limitations of using extrapolation methods to determine the VAT Taxable Base.

The Core of the Conflict Centered on the VAT Base Correction

The core of the conflict in this case centered on the VAT Base correction for March 2017 amounting to IDR 1,968,918.423.00. The Appellee argued that based on the results of accounts receivable reconciliation and the use of an extrapolation formula, there were taxable deliveries that should have been self-collected but remained unreported. The Appellee based this correction on Article 13 paragraph (1) of the KUP Law, which authorizes the determination of tax due based on audit findings. On the other hand, PT II strongly refuted these findings, stating that all deliveries had been properly documented with Tax Invoices. The discrepancies found by the auditor were claimed to be a result of the auditor's failure to accurately identify opening and closing receivable balances, as well as the inclusion of cash receipts unrelated to deliveries within the specific tax period.

The Tax Court Judges Legal Opinion Emphasizing the Validity of Evidence

The Tax Court Judges provided a legal opinion emphasizing the validity of evidence. The Judges viewed the extrapolation method used by the Appellee as presumptive and unsupported by actual goods flow evidence or transaction documents to prove unreported deliveries. During the trial, PT II successfully presented comprehensive evidence, including General Ledgers, bank statements, and reconciliations proving that the difference was purely a cut-off issue. The Judges reaffirmed that the burden of proof for unreported tax objects lies with the Appellee, and since the Appellee failed to prove the existence of actual goods/services flow beyond what was reported, the correction had to be overturned.

The Implication of This Decision Confirms Accounts Receivable Testing Limitations

The implication of this decision confirms that accounts receivable testing cannot stand alone without being supported by valid physical evidence of transactions or goods flow. For Taxpayers, this victory highlights the crucial importance of maintaining tidy General Ledger documentation and the ability to perform independent reconciliations between cash flow, receivables, and VAT reporting. This ruling serves as a reminder to tax authorities that the use of indirect audit techniques must not ignore the legal facts regarding the timing of tax liability and the material truth of transactions.
