Judicial Verdict: DGT Prohibited from Arbitrary Revenue Estimation Using Cost-to-Revenue Ratios!

Tax Dispute: VAT Timing and Progress Billing Principles for Konsorsium PT. WK - PT. TI

Legal certainty regarding the timing of Value Added Tax (VAT) obligations in the construction industry was reaffirmed through this Tax Court Decision. The dispute centered on the Respondent’s (DGT) correction of the VAT Base for the October 2014 Tax Period, amounting to IDR 22,564,088,084.00, derived from a cost extrapolation method. The Respondent assumed that Konsorsium PT. WK - PT. TI (Petitioner) had unreported deliveries due to a perceived imbalance between project cost realization and the revenue recognized in the financial statements.

Core Conflict: Cost Extrapolation Methodology vs. Progress Certificates

The core of this legal conflict lies in the audit methodology employed by the tax authorities. The Respondent utilized an indirect approach by comparing the total contract value of the DS LNG project against cost realization and extrapolating it proportionally. Conversely, the Petitioner presented an argumentative defense stating that in the construction industry, revenue recognition must strictly adhere to the Progress Billing principle. The Petitioner emphasized that all Tax Invoices were issued based on Progress Certificates approved by the project owner, in compliance with Article 13 paragraph (5) of the VAT Law.

Judicial Consideration: Material Truth and Delivery Evidence

The Board of Judges provided a resolution favoring the material truth of the documents. In their legal consideration, the Board stated that the cost extrapolation method used by the Respondent was speculative and could not supersede authentic evidence such as work progress certificates. The Board emphasized that VAT on construction services is due upon the delivery of services as evidenced by milestones/progress billing or upon receipt of payment. Since the Petitioner successfully demonstrated that all billings were supported by valid invoices and tax invoices, the assumption of hidden deliveries was ruled unproven.

Implications: Precedent for the Construction Sector

The implications of this decision are crucial for taxpayers in the infrastructure and construction sectors. This ruling serves as a strong precedent that the DGT cannot correct turnover solely based on cost ratios without evidence of actual service delivery. The strength of documentation, specifically Progress Certificates and contracts, remains the primary key to winning similar disputes. This serves as a reminder of the critical need for synchronization between accounting revenue recognition and the timing of tax invoice issuance according to VAT regulations.
