NPC's Real Property Tax Exemption Claim Fails: Ownership and Actual Use Matter

The Supreme Court has ruled that a government-owned and controlled corporation (GOCC) cannot claim real property tax exemptions for facilities it neither owns nor actually, directly, and exclusively uses, even if it assumed the tax obligations under a Build-Operate-Transfer (BOT) agreement. The ruling in National Power Corporation v. Province of Pangasinan (G.R. No. 210191, March 4, 2019) clarifies the limits of tax exemption privileges and reinforces the principle that taxation is the rule and exemption is the exception.

The Case: NPC and the Sual Power Plant

National Power Corporation (NPC) entered into an Energy Conversion Agreement with a private company, CEPA (later Mirant Sual Corporation), for the construction, operation, and maintenance of the Sual Coal-Fired Thermal Power Plant on a BOT basis. Under the agreement, NPC assumed responsibility for paying all real property taxes, and it paid these taxes from 1998 until the first quarter of 2003.

NPC then stopped paying, claiming exemption under the Local Government Code (R.A. No. 7160). Specifically, NPC invoked the provision exempting machineries and equipment actually, directly, and exclusively used by GOCCs engaged in power generation and transmission. NPC also sought classification of the properties as "special" for a lower assessment level, plus depreciation allowances for machinery.

The Central Issue: Legal Personality to Claim Exemption

The Court framed the pivotal question as whether NPC had legal personality and interest to claim these exemptions and privileges. The answer depended on whether NPC was the actual owner or beneficial user of the subject facilities.

The Court examined the BOT agreement and found that the private company, Mirant, owned the power station and all its machinery and equipment until the transfer date. Mirant also had the responsibility to manage, operate, and maintain the plant during the cooperation period. NPC's ownership was merely contingent—it would only vest upon transfer at the end of the BOT term.

Why NPC's Arguments Failed

NPC argued that it had legal interest as project owner and that real property is assessed based on actual use regardless of ownership. The Court acknowledged that a beneficial user may indeed be burdened with real property tax and may have personality to protest an assessment. However, NPC was neither the owner nor the possessor or beneficial user of the facilities.

The Court rejected NPC's characterization of Mirant as a mere service contractor. Under the BOT concept, the private proponent constructs, operates, and manages the facility for its own account, recovering its investment through defined compensation—not as a hired contractor paid upon task completion. Until the transfer date, Mirant was the actual, direct, exclusive, and beneficial owner and user.

The Effect of Assuming Tax Liabilities

The Court gave short shrift to NPC's argument that its contractual assumption of tax liabilities justified its claims. Such an undertaking does not create an exemption. To rule otherwise would allow an exempt entity to extend its privilege to a non-exempt entity, effectively circumventing the law on exemptions. The Court cited its earlier ruling in National Power Corporation v. Province of Quezon (624 Phil. 738 [2010]) on this point.

Practical Takeaways

• Exemption requires actual use. To claim exemption under the Local Government Code, the GOCC must prove it actually, directly, and exclusively uses the machinery and equipment—not merely that the property serves a public purpose.
• BOT arrangements shift tax exposure. In a BOT deal, the private proponent is the owner-user until transfer. A GOCC that assumes tax payments contractually remains liable for those payments but cannot claim the owner's exemptions.
• Contractual assumption is not a tax shield. Agreeing to pay taxes does not confer the legal personality to claim exemptions or privileges belonging to the actual owner-user.
• File exemption claims promptly. Claims for exemption must be supported by documentary evidence filed within a prescribed period from the declaration of the property.
• Local governments' right to collect must be upheld. The Court emphasized that prolonged litigation deprives LGUs of revenues needed for basic services, and their right to collect taxes due must be protected.
