Caltex (Philippines) Inc. vs. Central Board of Assessment Appeals and City Assessor of Pasay

The underground gasoline tanks were buried approximately six feet deep and connected by steel pipes to gasoline pumps located under the station shed, with the pumps attached to cement pads imbedded in the pavement.

Caltex retained ownership of the equipment, loaning it to gas station operators under lease agreements requiring return upon demand, while the landowner did not acquire ownership rights to the installed machinery.

The City Assessor of Pasay City characterized the entire assembly of pavement, improvements, and attached machinery as forming the gasoline service station business and assessed an annual realty tax of P4,541.10 on the equipment.

The City Board of Tax Appeals initially ruled the equipment was personal property, but the Central Board of Assessment Appeals reversed this determination, finding the items permanently affixed to the realty and therefore subject to taxation under the Real Property Tax Code.

Petitioner contended that as a lessee of the land, it could not immobilize its machinery by destination, and therefore the equipment remained personal property not subject to realty tax.

Caltex asserted that the definitions of real and personal property in Articles 415 and 416 of the Civil Code should govern the tax classification of the subject equipment.

Petitioner prayed for the setting aside of the Central Board's decision and a declaration that the gas station machinery and equipment constituted personal property exempt from realty tax.

The City Assessor maintained that the equipment was permanently attached and affixed to the tenement, specifically to the pavement and improvements constituting the gas station, through cement pads, steel pipes, and physical connections to the building structure.

The Central Board contended that the Civil Code definitions of real and personal property were inapplicable to tax assessment cases, which are governed by the specific provisions of the Assessment Law and Real Property Tax Code.

Respondents emphasized that the equipment served as appurtenances necessary to the operation of the gas station, without which the business would be useless, and therefore constituted taxable improvements regardless of ownership status or movability in nature.

**Substantive Issues:** Whether machinery and equipment permanently affixed to leased land by a lessee for business purposes constitutes real property subject to realty tax under the Real Property Tax Code and Assessment Law, notwithstanding Civil Code provisions classifying such items as personal property when installed by temporary right-holders.

**Substantive:** The machinery and equipment constitute taxable real property. As appurtenances to the gas station building or shed, permanently attached or affixed to the site or embedded therein, and necessary for the operation of the gas station business, they qualify as "improvements" and "machinery" under Sections 3(k) and (m) and Section 38 of the Real Property Tax Code. The Court distinguished _Davao Saw Mill Co._ (involving execution of judgment), _Board of Assessment Appeals vs. Manila Electric Co._ (involving franchise exemptions for movable poles), and _Mindanao Bus Co._ (repair shop tools), holding that improvements commonly taxed as realty may be considered personalty for other purposes. The Central Board did not commit grave abuse of discretion in upholding the tax assessment.

**Immobilization by Attachment for Taxation** — Machinery and equipment permanently attached or affixed to real estate, embedded in cement or pavement, and connected to building structures, constitute taxable real property under the Real Property Tax Code regardless of whether the owner of the machinery is also the owner of the land.

**Functional Necessity Test for Fixtures** — Equipment that serves as appurtenances necessary to the operation of a business conducted on real property, without which the business establishment would be useless, is considered a taxable improvement attached to the realty.

_"It is a familiar phenomenon to see things classed as real property for purposes of taxation which on general principle might be considered personal property."_

_"We hold that the said equipment and machinery, as appurtenances to the gas station building or shed owned by Caltex (as to which it is subject to realty tax) and which fixtures are necessary to the operation of the gas station, for without them the gas station would be useless, and which have been attached or affixed permanently to the gas station site or embedded therein, are taxable improvements and machinery within the meaning of the Assessment Law and the Real Property Tax Code."_

_"That ruling is an interpretation of paragraph 5 of article 415 of the Civil Code regarding machinery that becomes real property by destination... Here, the question is whether the gas station equipment and machinery permanently affixed by Caltex to its gas station and pavement (which are indubitably taxable realty) should be subject to the realty tax. This question is different from the issue raised in the Davao Saw Mill case."_
