The Boomerang Trap of Mining Services: Tax Court Annuls Hundreds of Billions in Corporate Income Tax Correction Due to Exclusive Contract Compliance

The application of the economic substance over form doctrine by the Directorate General of Taxes (DGT) in correcting the Cost of Goods Sold (COGS) and recognizing unrecorded Income from Non-Operating Activities related to mining activities, amounting to Rp57 billion in the PT SBB case, was ultimately overturned by the Tax Court Judges. The cost matching revenue principle asserted by the DGT was invalidated due to the existence of a Mining and Sales of Rocks Agreement which granted the Taxpayer an exclusive right to material supply in exchange for bearing the mining costs, making these expenses an integral part of COGS.

This case stemmed from a Corporate Income Tax (CIT) correction for the 2017 Tax Year. The DGT argued that the mining costs incurred by SBB for PT Pendawa Lestari Perkasa (PLP), the holder of the Mining Business Permit (IUP), should have been borne by PLP itself. Citing the Minerba Law, the DGT deemed SBB's expenditure as payment for mining services that should have been billed to PLP but were not reported. This triggered a Positive Correction of Non-Operating Income amounting to Rp31,061,381,919.00 and a Negative Correction to COGS Purchases of Rp20,880,768,385.00.

The Taxpayer, operating in the concrete industry, vehemently denied providing mining services. SBB presented the 2008 Agreement that obligated SBB to bear mining operational costs as the sole condition for obtaining the exclusive right to all andesite rock yield. SBB also confirmed the absence of any factual evidence, such as invoices or cash inflows, to support a service transaction, and asserted that the company's Business Field Classification (KLU) did not cover mining services.

The Tax Court Judges agreed with SBB. In their legal consideration, the Panel stated that the DGT failed to substantiate its correction. The existing commercial agreement was deemed to clearly prove that the expenditure had a legitimate business purpose and fulfilled the 3M principle (Obtaining, Collecting, Maintaining Income) as a cost of acquisition. Corrections based solely on assumptions and interpretations of sectoral regulations without concrete transaction evidence could not be sustained.

The implication of this decision is critical for companies with back-to-back agreements or prerequisite transactions in their supply chain. It affirms that the validity of an expense and income recognition must be grounded in the economic substance proven through agreements and supporting transaction documents, not merely assumptions of non-fiscal regulatory violations. If contract documents show exclusive benefits gained from bearing a cost, that cost is legitimately part of COGS.

In conclusion, the Panel of Judges annulled the CIT correction related to mining services. This decision sets an important precedent, reminding the DGT to focus not only on the formalities of sectoral regulations but also on the substance of the commercial agreements undertaken by the Taxpayer to conduct its business activities.
