Commissioner of Internal Revenue v. Court of Appeals
REITERATIONFacts
The Antecedents: Atlas Consolidated Mining and Development Corporation (ACMDC) was assessed by the Commissioner of Internal Revenue (CIR) for deficiency ad valorem percentage and fixed taxes, including increments, for the taxable years 1975 and 1976. The initial assessments amounted to P12,391,070.51 for 1975 and P13,531,466.80 for 1976. ACMDC protested these assessments, arguing that in computing the ad valorem tax on copper, refining and smelting charges should be deducted from the London Metal Exchange (LME) price, in addition to freight and insurance charges. The CIR contended that only freight and insurance were deductible under the law. Procedural History: ACMDC's protests were denied, leading it to file two separate petitions for review with the Court of Tax Appeals (CTA), which were consolidated. The CTA ruled that ACMDC was not liable for deficiency ad valorem taxes on copper and silver for 1975 and 1976, sustaining ACMDC's theory on deductions. However, the CTA found ACMDC liable for P1,572,637.48 in surcharges for late payment of ad valorem taxes on silver, gold, and pyrite, and for deficiency manufacturer's sales tax and contractor's tax. Both parties appealed to the Court of Appeals (CA). The CA, in CA-G.R. SP No. 25945, dismissed the CIR's petition, affirming the CTA's decision on the ad valorem tax computation. In CA-G.R. SP No. 26087, the CA modified the CTA's decision, further reducing ACMDC's liability by deleting certain surcharges related to silver, gold, and pyrite. The Petition: Two petitions for review on certiorari were filed with the Supreme Court. In G.R. No. 104151, the CIR questions the CA's affirmation of the CTA's ruling that smelting and refining charges should be deducted from the LME price in computing the ad valorem tax on copper. In G.R. No. 105563, ACMDC argues it is not liable for any deficiency tax assessments, specifically challenging the surcharges on silver, gold, and pyrite, and disputing liability for manufacturer's sales tax and contractor's tax. The Supreme Court consolidated these two cases for joint adjudication.
Issue(s)
Whether smelting and refining charges should be deducted from the London Metal Exchange (LME) price of copper wire bar in computing the ad valorem tax on copper concentrates. Whether ACMDC is liable for the 25% surcharge for alleged late filing of notice of removal or late payment of the ad valorem tax on silver, gold, and pyrite extracted during 1976. Whether ACMDC is liable for manufacturer's sales tax for 1975 on grinding steel balls allegedly borrowed by its competitor. Whether ACMDC is liable for contractor's tax and surcharge on the alleged lease of personal property during 1975 and 1976.
Ruling
The Supreme Court affirmed the Court of Appeals' decision in G.R. No. 104151, upholding the deduction of smelting and refining charges. The Court modified the Court of Appeals' decision in G.R. No. 105563 by exempting ACMDC from the payment of manufacturer's sales tax, surcharge, and interest for 1975, but upheld the assessment for contractor's tax.
Ratio Decidendi
On the deductibility of smelting and refining charges for ad valorem tax on copper: The Court held that the ad valorem tax is a severance tax imposed on the privilege of extracting minerals from the earth, computed on the actual market value of the mineral in its condition at the time of removal. While Section 246 of the Tax Code prohibits deductions from "gross output" except for ocean freight and insurance when sold abroad under CIF terms, this prohibition applies when the tax base is the value of the mineral at the mine site. In this case, ACMDC used the LME price of manufactured copper wire bar as a reference due to the absence of a market price for copper concentrate. Therefore, to approximate the actual market value of the copper concentrate at the mine site, all expenses incurred after its removal, including smelting and refining charges, must be deducted. The Court reiterated its ruling in Cebu Portland Cement Co. vs. Commissioner of Internal Revenue that when the market value of the finished product is used as the tax base, processing and manufacturing expenses must be deducted to arrive at the value of the raw mineral at the mine site. On the surcharge for late payment of ad valorem tax on silver, gold, and pyrite: The Court found ACMDC liable for the 25% surcharge. While ACMDC argued that the exact quantities of silver and gold could only be determined after smelting and refining, and pyrite after flotation, the Court noted that ACMDC's own assay reports estimated the commercial quantities of these minerals. The testimony of ACMDC's metallurgist indicated that laboratory testing determined the grades of copper, gold, and silver, and these assay reports were used as the basis for ad valorem tax payment. The Court found no merit in ACMDC's claim that pyrite was not removed from the mine site, as evidence showed deliveries to other companies and ACMDC had previously declared and paid ad valorem tax on pyrite for the same period, making it estopped from raising the issue later. On manufacturer's sales tax: The Court agreed with ACMDC that it was not liable for manufacturer's sales tax. The definition of a "manufacturer" under Section 194(x) of the Tax Code requires that the alteration of raw materials be for the purpose of sale or distribution to others, not for the manufacturer's own use or consumption. ACMDC produced grinding steel balls primarily for its own use, and the lending of these balls to other mining companies was considered an isolated transaction or accommodation, not an engagement in business with a view to profit. On contractor's tax: The Court found ACMDC liable for contractor's tax on the lease of its personal properties (plane, motor boat, dump truck). The evidence showed a series of transactions with substantial rental income reported for 1975 and 1976, indicating a habitual engagement in the leasing business, thus subjecting it to the contractor's tax. The Court also emphasized that tax assessments are presumed correct and the burden of proof is on the taxpayer to show otherwise.
Main Doctrine
The ad valorem tax on minerals is computed on the actual market value of the mineral in its condition at the time of removal from the earth, before substantial chemical or manufacturing processing. If the market value of the finished product is used as a base, expenses of processing and manufacturing must be deducted to approximate the value of the raw mineral at the mine site. A manufacturer's sales tax is imposed on persons engaged in the sale, barter, or exchange of articles, requiring continuity of action and profit motive, not merely isolated transactions or accommodations.
