Case
G.R. No. L-65773-74
Decision Date
Apr 30, 1987
BOAC, a British airline, contested Philippine tax assessments on ticket sales revenue. The Supreme Court ruled BOAC as a resident foreign corporation, deeming ticket sales income taxable in the Philippines, upholding deficiency taxes for 1968-1971.

Case Summary (G.R. No. 162299)

Petitioner

Commissioner of Internal Revenue, charged with assessing deficiency income taxes against BOAC for fiscal years 1959–1967 and 1968–1971, and denying BOAC’s refund claim and reconsideration requests.

Respondent

British Overseas Airways Corporation, which maintained no flight operations to or from the Philippines but sold tickets through local general sales agents (Warner Barnes & Co., then Qantas Airways) and received ticket proceeds in Philippine currency.

Key Dates

• Initial assessment for 1959–1963: 7 May 1968 (P2,498,358.56)
• Revised assessment for 1959–1967: 16 January 1970 (P858,307.79)
• Assessment for 1968–1971: 17 November 1971 (P549,327.43 plus penalties)
• CTA joint decision reversing CIR: 26 January 1983
• Supreme Court decision: 30 April 1987

Applicable Legal Framework

1987 Philippine Constitution governs income taxation. Tax Code definitions under Section 20 distinguish “resident” and “non-resident” foreign corporations. Section 24(b) prescribes tax rates and bases for resident foreign corporations’ net income from Philippine sources.

Core Issues

  1. Whether BOAC’s ticket-sale revenues in the Philippines constitute Philippine-source income subject to income tax.
  2. Whether BOAC is a resident foreign corporation doing business in the Philippines.
  3. If non-resident, whether BOAC’s Philippine gross income remains taxable at 35%.

Factual Background

BOAC lacked landing rights and did not perform carriage services in the Philippines outside brief temporary permits. Its sole Philippine presence was a general sales agent responsible for issuing tickets, collecting fares, and interline settlement with other carriers.

Proceedings Below

BOAC protested the deficiency assessments, paid under protest, sought refunds, and filed separate petitions before the CTA (Cases 2373 and 2561), which were later tried jointly. The CTA set aside the assessments and denied the refund.

Tax Court’s Ruling

The CTA held that ticket sales were not Philippine-source income since BOAC performed no transport services within the Philippines; accordingly, all assessments were canceled and the refund claim granted.

Revenue’s Contentions

• Ticket proceeds arise from Philippine activity and are Philippine-sourced.
• BOAC’s use of a local agent and continuity of ticket sales constitute “doing business” and render it a resident foreign corporation.
• Alternatively, unperformed services abroad remain taxable if the proceeds originate in Philippine territory.

Resident Foreign Corporation Analysis

Engaging a general sales agent on a continuous basis to sell tickets and allocate fares under IATA rules constitutes “trade or business” in the Philippines. BOAC is therefore a resident foreign corporation liable on net Philippine-source income under Section 24(b)(2).

Characterization of Income

“Gross income” includes all gains from business transactions, explicitly covering proceeds from the sale of transport documents. A ticket embodies mutual contractual obligations—fare payment in the Philippines and carriage abroad—but the sale transaction and payment occur within Philippine territory.

Source of Income Determination

The source is the activity producing the income. Ticket sales in the Philippines, with payments in Philippine currency and enjoyment of government protection, establish a Philippine source. Absence of physical carriage here does not alter the situs of ticket-sale proceeds.

Scope of Enumeration in Section 37

Section 37(a) lists example items of Philippine-source income but is not exhaustive. The broad definition of gross income and the “income from any source whatever” clause encompass ticket-sale proceeds.

Services Rule vs. Sales Rule

Income from services is sourced where
