Excise Tax Exemption for International Carriers: A Landmark Ruling on Refunds

The Supreme Court has affirmed that oil companies are entitled to refunds or tax credits for excise taxes paid on petroleum products sold to international carriers. The ruling in Commissioner of Internal Revenue v. Pilipinas Shell Petroleum Corporation (G.R. No. 180402, February 10, 2016) resolves a long-standing question about who bears the burden of excise tax when selling fuel to international airlines and shipping lines. The decision reinforces the Philippines' commitment to international agreements and provides clear guidance for businesses in similar situations.

The Facts of the Case

Pilipinas Shell Petroleum Corporation sold and delivered petroleum products to various international carriers of Philippine and foreign registry for use outside the Philippines from November 2000 to March 2001. A portion of these sales came from its own tax-paid inventories, while another portion was sourced from Petron Corporation under a loan or borrow agreement.

Pilipinas Shell filed claims for refund or credit of excise taxes paid on these sales, totaling over P49 million. When the Bureau of Internal Revenue (BIR) failed to act on the claims, Pilipinas Shell brought the matter to the Court of Tax Appeals (CTA). The CTA granted the claim but reduced the amount to P39,305,419.49, disallowing the portion sourced from Petron since Pilipinas Shell was not the proper party to claim that amount.

The Core Issue

The central question was whether a local manufacturer or seller of petroleum products could claim a refund of excise taxes paid on products sold to international carriers, which are exempt from such taxes under the National Internal Revenue Code (NIRC).

The Commissioner of Internal Revenue argued that excise taxes are levied on the manufacturer or producer, regardless of the purchaser. Under this view, the exemption granted to international carriers merely meant the manufacturer could not pass on the tax to the buyer—but the manufacturer still had to shoulder it.

The Supreme Court's Ruling

The Supreme Court denied the CIR's petition and affirmed the refund. In doing so, it applied the doctrine of stare decisis, following its earlier ruling in Commissioner of Internal Revenue v. Pilipinas Shell Petroleum Corporation (G.R. No. 188497).

Initially, the Court had sided with the CIR in that earlier case, ruling that the exemption under the NIRC only allowed international carriers to purchase petroleum products without the excise tax component as an added cost. However, upon reconsideration, the Court reversed itself.

The Court recognized that denying refunds to domestic manufacturers would have serious implications for the Philippines' commitments under the Chicago Convention, which established the legal framework for international civil aviation. While Article 24(a) of the Convention addresses customs duties on fuel retained on board aircraft, the exemption of airlines from national taxes on fuel has become a standard element of bilateral air service agreements between countries.

The Court reasoned that if oil companies were forced to absorb the excise tax, they would either stop selling to international carriers or raise prices—both outcomes that would harm the Philippine economy and tourism industry. Worse, the government risked retaliatory action under several bilateral agreements.

The Court held that Pilipinas Shell, as the statutory taxpayer directly liable to pay the excise tax on its petroleum products, was entitled to a refund or credit of excise taxes paid for products sold to international carriers, which are exempt under the NIRC.

The Nature of Excise Tax

The Court also cited its ruling in Chevron Philippines, Inc. v. Commissioner of Internal Revenue (G.R. No. 210836), which applied the same principle. There, the Court emphasized that excise tax is a tax on property, not on the person. Therefore, an exemption from excise tax must be construed in favor of the petroleum products on which the tax was initially imposed, rather than limited to the buyer.

Practical Takeaways

• Oil companies can claim refunds for excise taxes paid on petroleum products sold to international carriers, provided they are the statutory taxpayers who directly paid the tax.
• The exemption follows the product, not just the buyer. Since excise tax is a tax on property, the exemption under the NIRC applies to the petroleum products themselves when sold to exempt entities.
• International agreements matter in tax interpretation. Philippine courts will consider commitments under international conventions and bilateral agreements when interpreting tax exemptions.
• Keep proper documentation. Claims must be filed within the prescriptive period, and taxpayers should be prepared to prove that sales were made to qualified international carriers.
• The ruling applies to similar situations. The same principle was extended to sales to tax-exempt entities like the Clark Development Corporation, showing broad application beyond international carriers.
