📌 Case Digest: Aces Philippines Cellular Satellite Corporation v. Commissioner of Internal Revenue
G.R. No. 226680 | August 30, 2022
===========================
📄 Facts
In 1995, the Philippine Long Distance Telephone Company (PLDT) entered into agreements to build and operate telecommunication gateways in the Philippines. PLDT later transferred its rights to its subsidiary, Aces Philippines Cellular Satellite Corporation (Aces Philippines), which entered into an Air Time Purchase Agreement with Aces Bermuda, a non-resident foreign corporation (NRFC).
Under the agreement, Aces Bermuda provided satellite communications air time (Aces Services) using the “Aces System,” consisting of a satellite in geostationary orbit, a Network Control Center in Indonesia, and terrestrial gateways and terminals located in the Philippines. Aces Philippines paid air time fees based on “Billable Units,” representing actual usage of satellite time for successful calls.
In 2007, the Bureau of Internal Revenue (BIR) audited Aces Philippines and found that in 2006, it paid ₱199,312,169.00 in air time fees to Aces Bermuda without withholding the 35% Final Withholding Tax (FWT). The BIR ruled that the payments constituted income from sources within the Philippines. Aces Philippines protested, arguing that the income was sourced outside the Philippines because signal transmission occurred in outer space and system control was based in Indonesia.

❓ Issues
1️⃣ Whether the satellite air time fee payments to Aces Bermuda constitute income from sources within the Philippines, subject to Final Withholding Tax.
2️⃣ Whether the simultaneous imposition of deficiency and delinquency interest is valid.
-----------------------------
⚖️ Ruling
The Supreme Court DENIED the petition and held that the income was sourced within the Philippines.
1️⃣ Situs of Income
To determine the situs of income, the Court applied a two-step analysis: (a) identify the income-producing activity, and (b) determine the location where such activity is completed. The Court ruled that the income-producing activity was not the mere transmission of signals in outer space, but the successful routing and receipt of calls through terrestrial gateways in the Philippines.
2️⃣ Completion of Service
The service rendered by Aces Bermuda was deemed completed only when the satellite signal reached the Philippine gateways. At the point of transmission in space, the service was merely in progress. Notably, air time fees accrued only when calls were successfully completed and utilized by Philippine subscribers; incomplete or unanswered calls were not billable.
3️⃣ Situs of Activity
The situs of the income-producing activity is the Philippines, as the gateways—essential to the delivery of the service—are located within Philippine territory. The Court emphasized that telecommunications is a state-regulated industry, implicating Philippine sovereignty, and that Aces Bermuda’s business depended on these local facilities.
4️⃣ Final Withholding Tax
As a non-resident foreign corporation earning income from Philippine sources, Aces Bermuda is subject to a 35% final tax on its gross income, which Aces Philippines was required to withhold at source.
5️⃣ Interest on Tax Deficiency
Under the 1997 Tax Code, the simultaneous imposition of deficiency and delinquency interest was allowed. However, with the effectivity of the TRAIN Law (R.A. No. 10963) on January 1, 2018, such simultaneous imposition is no longer permitted. Thus, both interests apply only until December 31, 2017, and from January 1, 2018 onwards, only a single interest rate applies.
===========================
💡 Doctrine
Income is sourced where the income-producing activity is completed, not where preparatory or intermediate acts occur. In telecommunications services, income is sourced in the country where the call is successfully routed and received, even if transmission passes through outer space or foreign control centers.
