Case Summary (G.R. No. 171383)
Key Dates
Transactions at issue: purchases of aviation jet fuel from Petron for use on international flights from 1 January 1999 to 31 December 1999, divided into two periods: 1 January–30 June 1999 and 1 July–31 December 1999. Court of Tax Appeals (CTA) decisions denying Silkair’s refund claims: 20 October 2005 and 5 January 2006; Supreme Court consolidated review and decision rendered in 2008. Applicable constitutional framework: 1987 Philippine Constitution (decision date is post-1990).
Applicable Law and Treaties
Primary statutory provisions: NIRC (1997) provisions on excise taxes — Section 129 (definition of excise tax), Section 130 (filing/payments by manufacturers before removal), Section 135 (exemptions for petroleum products sold to international carriers and exempt entities), Section 148(g) (specific excise on aviation jet fuel at P3.67 per liter), and Section 204(c) (claim for refund/credit requirements). International instrument: Article 4 of the Air Transport Agreement between the Philippines and Singapore, providing exemption from customs duties, inspection fees and other duties or taxes for fuel and other supplies introduced into or taken on board by a designated airline of the other Contracting Party.
Statement of Facts
Silkair purchased aviation jet fuel from Petron for its international flights during 1999. Invoices and delivery receipts showed that P3.67 per liter was charged as excise tax and remitted to the BIR. For the two six-month periods petitioned, the amounts allegedly paid (through Singapore Airlines Ltd. and remitted by Petron) were P4,239,374.81 (Jan–Jun 1999) and P4,831,224.70 (Jul–Dec 1999). Silkair formally filed claims for refund/issuance of tax credit certificates asserting exemption under Section 135 of the NIRC and Article 4 of the Air Agreement.
Petitioner’s Contentions
Silkair asserted that (1) it was an exempt international carrier under Section 135 and the Air Agreement and thus entitled to a refund of excise taxes paid in error; (2) the economic reality was that Silkair paid the excise because Petron merely remitted amounts billed to Silkair, so denying Silkair the right to seek refund would make recovery contingent on Petron’s actions and potentially deprive Silkair of property; (3) a tax exemption is a personal privilege of the grantee and should not be rendered useless by a rule that only the seller/manufacturer may claim refunds; and (4) equities and substance over form support allowing the exempt grantee to obtain refund when the seller has passed the charge to it.
Respondent’s Contentions
The Commissioner of Internal Revenue maintained that excise taxes on petroleum products are indirect taxes imposed by law on manufacturers/producers (Petron), who are the statutory taxpayers. As an indirect tax, the economic burden may be shifted to purchasers, but legal liability remains with the manufacturer; hence, only Petron, as the person statutorily liable and who filed excise tax returns and remitted payment, is entitled to claim any refund under Section 204(c). The BIR’s administrative position and later Revenue Regulations (e.g., RR No. 3-2008) also require manufacturers to pay excise taxes on removal and then, subject to procedures, claim refund or credit if exemptions apply.
CTA Rulings — Core Findings
The Court of Tax Appeals (En Banc) held that the excise tax on petroleum products is an indirect tax imposed on the manufacturer (Petron) and collected upon removal. Although Petron may shift the economic burden to purchasers (Silkair) by itemizing the tax in invoices, such shifting transfers burden but not statutory liability. Under the NIRC and prevailing jurisprudence, the statutory taxpayer — the person on whom the law imposes the tax and who paid it — is the proper claimant for refund. The CTA therefore denied Silkair’s refund claims and suggested that Silkair should have presented valid exemption certificates to Petron prior to purchase so Petron would not have passed on the tax.
Issue Presented to the Supreme Court
Whether Silkair, as an exempt international carrier, is the proper party to claim a refund or tax credit for excise taxes reflected in the invoices for aviation jet fuel and remitted by Petron, despite the statutory imposition and payment of the excise tax by Petron as manufacturer.
Supreme Court Ruling and Legal Reasoning
The Supreme Court affirmed the CTA. It reiterated the fundamental distinction between direct and indirect taxes: an indirect tax (such as an excise) is legally imposed on a specific person (the manufacturer) but may have its economic burden shifted to others (buyers). The Court emphasi

- General Terms & Conditions (Supply Contract) clause 11.3: If Buyer is entitled to purchase fuel free of taxes, Buyer shall timely deliver to Seller a valid exemption certificate for such purchase.
- Evidence in record:
- Aviation Delivery Receipts and Invoices that show P3.67 per liter excise tax separately billed (numerous exhibits enumerated in the rollo and CTA rollo).
Petitioner’s Contentions and Legal Theories
- Petitioner's central contention: It is exempt from payment of excise taxes under Section 135 of the NIRC and under Article 4 of the Air Agreement; therefore it is entitled to a refund or issuance of tax credit certificate for excise taxes it paid.
- Petitioner asserts practical reality: Although Petron remitted the excise tax to the BIR, petitioner in reality paid the tax as reflected in invoices and delivery receipts; thus petitioner should be able to claim recovery directly from the BIR.
- Argument on rights and equity:
- If only Petron may claim refund, petitioner’s right to recover would depend wholly on Petron’s actions, which are not under petitioner’s control; delay or inaction by Petron would bar petitioner’s claim and deprive petitioner of property.
- Holding that only the seller can claim the refund would nullify the tax exemption granted to petitioner by statute and treaty.
- Tax exemptions are personal privileges of the grantee; an exemption granted to a buyer cannot be availed of by the seller. Therefore, the seller (Petron) cannot legally claim the refund in lieu of the grantee (Silkair).
- Reliance on precedent and principle:
- Cites Maceda v. Macaraig, Jr. and a quoted opinion of the Secretary of Justice to argue that
