Implications of Burden of Proof: Tax Court Rejects Tax Base Correction Based Solely on Raw Material Flow Testing

The Tax Court's decision clearly highlights the failure of tax authorities to uphold substantive tax principles, particularly in the context of VAT in the manufacturing sector. This dispute involves PT SB, which appealed against the correction of the VAT Tax Base made by the Directorate General of Taxes (DGT). The core of the dispute revolves around the methodology for determining Output VAT, where the DGT attempted to increase the VAT DPP based solely on the results of the physical flow test of raw materials for yarn, which were claimed as unreported sales of Taxable Goods (BKP). The Panel of Judges' decision, which granted the appeal in its entirety, sets an important precedent regarding the limits of the authority to correct VAT.

The dispute arose when the Directorate General of Taxes (DGT), through an audit, conducted a flow of goods test on PT SB's yarn raw materials for the August 2018 Tax Period. The auditor suspected an unaccounted-for yarn discrepancy (shortage) in production and inventory reports, and unilaterally assumed this discrepancy was the sale of Taxable Goods (BKP) subject to VAT but not yet reported. Consequently, the DGT issued a correction to the VAT Taxable Goods (DPP). PT SB vehemently denied the correction. PT SB's crucial argument was that VAT is a consumption tax levied on the delivery of BKP/JKP supported by a valid Tax Invoice. Output VAT cannot be calculated solely on the difference in physical stock of raw materials, as this falls within the scope of calculating the Cost of Goods Sold (HPP) in Income Tax, not determining the VAT Taxable Goods (DPP). Furthermore, PT SB successfully demonstrated that the DGT's flow of goods calculation contained an error regarding the difference in yarn usage, which was actually nil.

In its legal considerations, the Panel of Judges explicitly upheld the principle of burden of proof. The Panel stated that the Directorate General of Taxes, as the party making the correction, is obliged to prove the truth and validity of the correction with facts and a strong legal basis. After reviewing the evidence from both parties, the Panel believed that the Directorate General of Taxes failed to provide concrete evidence of the delivery of the corrected BKP (such as the buyer's identity, the transaction date, or the Tax Invoice that should have been issued). The absence of valid sales evidence rendered the correction to the VAT DPP baseless. The Panel also affirmed that the counter-calculation presented by PT SB, which showed a zero difference in thread usage, was presented in full, thus further convincing the Panel's view. Thus, the Panel of Judges was confident in granting the entire appeal.
