Tax Refunds for International Carriers: Who Really Owns the Claim?

Silkair (Singapore) Pte. Ltd. learned a hard lesson about Philippine tax procedure and litigation deadlines when its claim for a multi-million peso excise tax refund was denied. The Supreme Court’s 2008 ruling in Silkair (Singapore) Pte., Ltd. v. Commissioner of Internal Revenue (G.R. No. 173594) clarifies who may claim a refund of an indirect tax and underscores the strict rules on legal representation. The case offers practical guidance for foreign carriers and any taxpayer dealing with indirect levies.

The Dispute

Silkair, a Singaporean airline with a Philippine representative office, operated routes connecting Singapore, Cebu, and Davao. Between January and June 2000, it purchased jet fuel from Petron Corporation and paid over ₱4.5 million in excise taxes. Believing it was exempt under the National Internal Revenue Code (NIRC) of 1997 and the Air Transport Agreement between the Philippines and Singapore, Silkair filed for a refund with the Bureau of Internal Revenue. When the BIR failed to act, Silkair took its case to the Court of Tax Appeals (CTA).

The CTA’s Second Division denied the claim. It ruled that the excise tax on petroleum products is imposed on the manufacturer or producer—Petron—not on the buyer. Even if Petron shifted the tax burden to Silkair by adding it to the price, the amount passed on was no longer a tax but part of the purchase price. Only the statutory taxpayer, Petron, could claim the refund.

The Procedural Hurdle

Before the Supreme Court could even reach the merits, it had to settle a procedural question: was Silkair’s appeal to the CTA En Banc filed on time?

The timeline was critical. The CTA Second Division denied Silkair’s motion for reconsideration on September 22, 2005. A copy was received by Silkair’s original counsel, JGLaw, on October 3, 2005. However, a new law firm, the Bengzon Law Firm, had entered its appearance on September 12, 2005, and only received its copy of the resolution on October 14, 2005. JGLaw filed its formal notice of withdrawal on October 13, 2005. Silkair filed its petition for review with the CTA En Banc on November 17, 2005—well beyond the 15-day reglementary period if counted from October 3.

The Supreme Court held that the appeal was indeed filed out of time. Under Section 26, Rule 138 of the Rules of Court, a lawyer’s withdrawal from a case requires the client’s written consent filed in court. Since JGLaw had not yet withdrawn when it received the resolution on October 3, it remained Silkair’s counsel of record. Service upon one counsel of record is service upon all, and notice to counsel is notice to the client. The Court distinguished an earlier case cited by Silkair, noting that the controlling rule is that the counsel of record remains the proper recipient of court notices until formal withdrawal or substitution.

The Merits: Who Is the Statutory Taxpayer?

Despite the procedural dismissal, the Court addressed the substantive issue. Silkair argued that it was exempt from indirect taxes under the Air Transport Agreement, which exempted fuel from customs duties, inspection fees, and other duties or taxes. It cited Maceda v. Macaraig, Jr., where the National Power Corporation’s exemption from all forms of taxes was held to include indirect taxes.

The Court rejected this argument. Under the NIRC, the excise tax on petroleum products is paid by the manufacturer or producer before removal from the place of production. Petron, not Silkair, was the statutory taxpayer. When Petron shifted the tax burden to Silkair, the additional amount became part of the price of the goods—not a tax paid by Silkair.

The Court also clarified that a general exemption from taxes does not automatically include indirect taxes. In Commissioner of Internal Revenue v. Philippine Long Distance Telephone Company, the Court explained that an exemption from indirect taxes requires clear legislative intent. The exemption in the NIRC and the Air Transport Agreement did not contain such a clear grant. Tax exemptions are construed strictly against the taxpayer and liberally in favor of the taxing authority.

Practical Takeaways

• Know who the statutory taxpayer is. For excise taxes on petroleum products, the manufacturer or producer is the one who pays the tax and the only one who can claim a refund. A buyer who merely bears the economic burden has no standing to seek a refund.
• A shifted tax is no longer a tax. When a seller passes on an excise tax to a buyer, the amount becomes part of the purchase price. The buyer cannot claim it as a tax paid.
• Exemptions are narrow. A tax exemption does not extend to indirect taxes unless the law clearly says so. General language about being exempt from taxes or duties is usually not enough.
• Respect the rules on counsel of record. A new lawyer’s entry of appearance does not automatically relieve the old lawyer. Formal withdrawal must be filed in court. Until then, notices served on the old counsel bind the client.
• Deadlines are strict. The 15-day period to appeal a CTA decision runs from receipt by the counsel of record. Missing it is fatal, even if a new lawyer was engaged earlier.
