Commissioner of Internal Revenue vs. British Overseas Airways Corporation

A foreign corporation maintaining a general sales agent in the Philippines to sell airline tickets is a resident foreign corporation "engaged in trade or business" in the Philippines; consequently, income derived from such ticket sales constitutes income from sources within the Philippines subject to Philippine income tax, because the source of income is the property, activity, or service that produced it—in this case, the sales activity occurring within Philippine territory—regardless of whether the actual carriage of passengers or cargo is performed entirely outside the country.

The case arises from the taxation of international air carriers operating under the Interline Air Transport Association (IATA) system, which allows member airlines to sell tickets covering routes operated by other members. During the relevant assessment periods (1959-1971), international taxation principles regarding the characterization of income from ticket sales—whether as sales of personal property or as compensation for services—remained unresolved, creating uncertainty as to whether such income constituted Philippine-source income subject to territorial tax jurisdiction or foreign-source income exempt from Philippine tax.

• British Overseas Airways Corporation (BOAC) is a 100% British Government-owned corporation organized and existing under the laws of the United Kingdom, engaged in the international airline business as a member-signatory of the Interline Air Transport Association (IATA), which enables member airlines to sell transportation tickets over the routes of other airline members.

• During the periods covered by the disputed assessments (fiscal years 1959 to 1967 and 1968-69 to 1970-71), BOAC had no landing rights for traffic purposes in the Philippines and was not granted a Certificate of Public Convenience and Necessity by the Civil Aeronautics Board, except for a temporary nine-month permit partly in 1961 and partly in 1962; consequently, BOAC did not carry passengers or cargo to or from the Philippines during the relevant assessment periods.

• BOAC maintained a general sales agent in the Philippines—initially Warner Barnes and Company, Ltd., and later Qantas Airways—which was responsible for selling BOAC tickets covering passengers and cargo for international routes (transport between points outside the Philippines).

• The general sales agents engaged in the following activities: selling and issuing tickets; breaking down the whole trip into series of trips corresponding to different airline companies; receiving the fare for the whole trip; and allocating proceeds to the various airline companies on the basis of their participation in the services rendered through the mode of interline settlement as prescribed by the IATA Agreement.

• The CIR assessed BOAC deficiency income taxes for the fiscal years 1959-1967 (in the amount of P858,307.79) and 1968-71 (in the amount of P534,132.08), plus compromise penalties and interest, based on the gross revenue realized from the sales of passage documents in the Philippines.

• BOAC is a resident foreign corporation engaged in trade or business within the Philippines through its general sales agents, making it subject to tax upon its total net income from all sources within the Philippines under Section 24(b)(2) of the National Internal Revenue Code.

• The revenue derived from the sales of BOAC tickets in the Philippines constitutes income from Philippine sources because the source of an income is the property, activity, or service that produced the income; the sale of tickets in the Philippines is the activity that produces the income, and the tickets exchanged hands and were paid for in Philippine currency within Philippine territory.

• Section 37 of the Tax Code, which enumerates items of gross income from sources within the Philippines, is not an exclusive enumeration; the absence of specific mention of income from ticket sales does not render such income exempt from taxation as Philippine-source income.

• The absence of flight operations to and from the Philippines is not determinative of the source of income or the site of income taxation; the test of taxability is the "source," meaning the activity or property that produced the income, not the location where the subsequent transportation service is rendered.

• The dismissal of the appeal in Japan Airlines v. Commissioner of Internal Revenue does not constitute res judicata because that case involved the common carrier's tax (an excise tax on the activity of transportation), whereas the present case involves income tax (a direct tax on income), constituting different subject matters.

• BOAC is not a resident foreign corporation but a non-resident foreign corporation because it had no landing rights in the Philippines, maintained no office or place of business, and was not engaged in trade or business within the country during the relevant periods; it merely maintained a sales agent for off-line ticket sales.

• Income derived from transportation is income for services, and the place where the services are rendered determines the source; since BOAC performed the actual carriage of passengers and cargo entirely outside the Philippines, the income derived is from sources without the Philippines and is therefore not subject to Philippine income tax.

• The sale of tickets is merely incidental to the principal activity of transportation; the true source of the income is the service of carriage, not the sale of the piece of paper (the ticket), which is merely evidence of the contract of carriage.

• The Supreme Court's dismissal for lack of merit of the appeal in Japan Airlines v. Commissioner of Internal Revenue constitutes res judicata by analogy, barring the present assessment, because that case held that the mere sale of tickets without physical carriage does not subject a carrier to the common carrier's tax.

• Alternatively, if BOAC is considered a non-resident foreign corporation, it should only be taxed at 35% of gross income from sources within the Philippines, but since the income is from sources without, no tax is due.

• Procedural Issues: Whether the dismissal of the appeal in Japan Airlines v. Commissioner of Internal Revenue constitutes res judicata, barring the present action for deficiency income tax based on the same factual predicate of ticket sales without landing rights.

• Substantive Issues: (1) Whether BOAC is a resident foreign corporation engaged in trade or business in the Philippines or has an office or place of business therein; (2) Whether the revenue derived by BOAC from sales of tickets in the Philippines for air transportation constitutes income from Philippine sources subject to Philippine income tax; and (3) Whether BOAC is alternatively liable as a non-resident foreign corporation on gross income from sources within the Philippines at the rate of 35%.

• Procedural: The Supreme Court held that the dismissal in Japan Airlines v. Commissioner of Internal Revenue does not constitute res judicata because that case involved the common carrier's tax, which is an excise tax levied on the activity of transportation performed within the Philippines, whereas the present case involves income tax, which is a direct tax on the income of persons and entities derived from any source; since the two cases treat of different subject matters and causes of action, the decision in one does not bar the other.

• Substantive: The Court ruled that BOAC is a resident foreign corporation because maintaining a general sales agent in the Philippines constitutes "engaging in trade or business" requiring continuity of commercial dealings and the performance of acts or functions normally incident to the purpose of its organization as an international air carrier. The Court further held that the income from ticket sales is income from sources within the Philippines because the source of income is the activity that produced it—the sale of tickets occurring within Philippine territory where payments were made in Philippine currency—and not the location where the subsequent transportation service is rendered. The Court ordered BOAC to pay the deficiency income tax for fiscal years 1968-69 to 1970-71 plus 5% surcharge and 1% monthly interest, and denied the claim for refund for the earlier period.

• Source of Income Doctrine — The source of income is defined as the property, activity, or service that produced the income; for income to be considered from sources within the Philippines, it is sufficient that the income is derived from activity within the country, and the physical location of payment or the subsequent performance of services outside the country does not alter the Philippine source of the income generated by the local activity.

• Resident Foreign Corporation Doctrine — A foreign corporation is considered "engaged in trade or business" in the Philippines when it demonstrates continuity of conduct and intention to establish continuous business, such as through the appointment of a local general sales agent performing functions normally incident to and in progressive prosecution of the corporation's business objectives, even in the absence of physical facilities or landing rights in the country.

• Res Judicata in Tax Litigation — The principle of res judicata applies only where there is identity of parties, subject matter, and cause of action; a judicial decision interpreting and applying one type of tax (e.g., excise tax on common carriers) does not bar a subsequent action involving a different type of tax (e.g., income tax) on the same factual transaction because they involve different statutory provisions, legal bases, and governmental interests.

• "The source of an income is the property, activity or service that produced the income."

• "The absence of flight operations to and from the Philippines is not determinative of the source of income or the site of income taxation."

• "The word 'source' conveys one essential idea, that of origin, and the origin of the income herein is the Philippines."

• "In consideration of such protection, the flow of wealth should share the burden of supporting the government."

• "The sale of tickets in the Philippines is the activity that produces the income. The tickets exchanged hands here and payments for fares were also made here in Philippine currency."

• "The site of the source of payments is the Philippines. The flow of wealth proceeded from, and occurred within, Philippine territory, enjoying the protection accorded by the Philippine government."

• Howden & Co., Ltd. v. Collector of Internal Revenue, 13 SCRA 601 (1965) — Cited for the fundamental definition that the source of an income is the property, activity, or service that produced the income, which the Court applied to determine that the ticket sales activity constituted the source.

• The Mentholatum Co., Inc. v. Mangaliman, 72 Phil. 524 (1941) — Cited for the test of what constitutes "doing business" by a foreign corporation, requiring continuity of commercial dealings and arrangements.

• Madrigal and Paternol v. Rafferty, 38 Phil. 414 (1918) — Cited for the definition of income as a "flow of wealth" distinct from capital or principal, supporting the characterization of ticket sale proceeds as taxable income.

• British Trader's Insurance Co., Ltd. v. Commissioner of Internal Revenue, 13 SCRA 719 (1965) — Cited to establish that Section 37 of the Tax Code, enumerating items of Philippine-source income, is not an exclusive enumeration and does not preclude taxation of other income streams derived from activities within the Philippines.

• Manila Gas Corporation v. Collector of Internal Revenue, 62 Phil. 895 (1935) — Cited for the principle that the origin of the income determines its source, reinforcing the holding that income originating from sales activities in the Philippines is Philippine-source income.

• Commissioner of Internal Revenue v. U.S. Lines, Co., 5 SCRA 175 (1962) — Cited to distinguish the common carrier's tax as an excise tax on the business of transportation, which can only be levied when acts are done within Philippine jurisdiction, thereby supporting the rejection of the res judicata argument based on the JAL case.

• Japan Airlines v. Commissioner of Internal Revenue, G.R. No. L-30041 (1969) — Distinguished on the ground that it involved the common carrier's tax (an excise tax), not income tax, and therefore its dismissal did not bar the present income tax assessment against BOAC.

• Section 20(h) and (i) of the National Internal Revenue Code of 1977 — Definitions of "resident foreign corporation" (engaged in trade or business or having an office in the Philippines) and "non-resident foreign corporation" (not engaged in trade or business and no office in the Philippines), which determined the classification of BOAC for tax rate purposes.

• Section 24(b)(2) of the National Internal Revenue Code — Imposes tax on resident foreign corporations upon the total net income received in the preceding taxable year from all sources within the Philippines, the provision under which BOAC was held primarily liable.

• Section 29(3) of the National Internal Revenue Code — Defines gross income inclusively as gains, profits, and income derived from any source whatever, supporting the broad taxation of ticket sale proceeds.

• Section 37(a), (c), and (e) of the National Internal Revenue Code — Enumerate items of gross income from sources within and without the Philippines, including compensation for services performed within (Section 37(a)(3)) or without (Section 37(c)(3)) the Philippines, and provide rules for apportionment of income from transportation services rendered partly within and partly without (Section 37(e)).

• Presidential Decree No. 69 (November 24, 1972) — Amended Section 24(b)(2) to impose a tax of 2.5% on gross Philippine billings of international carriers, which the Court noted mooted the source-of-income conflict for periods subsequent to its promulgation.

• Presidential Decree No. 1355 (April 21, 1978) — Provided the statutory definition of "gross Philippine billings" as including gross revenue realized from uplifts anywhere in the world from passage documents sold in the Philippines.

• Revenue Regulations No. 2, Sections 155, 159, 163, and 164 — Cited in the dissenting opinion regarding rules for sourcing income from services, sales of personal property, and specific utility services (steamship and telegraph/cable), supporting the characterization of transportation as a service sourced where rendered.

• Chief Justice Teehankee — Concurred in the result, emphasizing that while the majority and dissent differed on the characterization of the taxable income (sales versus services), the conflict became moot after November 24, 1972, when Presidential Decree No. 69 imposed a 2.5% tax on gross Philippine billings for international carriers, replacing the net income tax approach and eliminating the practical significance of the source-of-income debate for subsequent taxable periods.

• Justice Feliciano — Dissented from the majority opinion, arguing that the transactions should be characterized as contracts of service (carriage of passengers) rather than sales of personal property; because transportation is a service and the source of service income is the place where the service is rendered (outside the Philippines), and because Section 37(e) of the Tax Code treats transportation income as sourced where the service is performed, the income was derived from sources without the Philippines and was not subject to Philippine income tax; further argued that the ticket is merely evidence of the contract of carriage and the payment represents compensation for the undertaking to transport, making the location of carriage the determinative factor.
