Benguet Corporation v. Central Board of Assessment Appeals

Summary

Benguet Corporation challenged a P11,319,304.00 realty tax assessment on its tailings dam and submerged land, arguing the dam was not a separately assessable improvement but an integral part of the mine. The Supreme Court dismissed the petition, establishing important precedent that mining infrastructure can constitute taxable improvements. The Court held that the tailings dam qualifies as an 'improvement' under the Real Property Tax Code because it is permanent in character, enhances the mine's value and utility, and meets the Civil Code definition of immovable property as a construction adhered to the soil. The decision distinguished cases where facilities were deemed integral to operations, finding that the tailings dam could function independently and exclusively benefited the petitioner. The Court sustained the P50.00 per square meter valuation as reasonable, respecting the expertise of tax assessment agencies. However, penalties were set aside as the Court found Benguet Corporation acted in good faith without intent to evade taxes. This landmark taxation case clarifies the scope of assessable improvements for realty tax purposes in the mining industry.
