Excise Tax on Petroleum: Who Bears the Burden When International Carriers Are Involved

The Supreme Court’s 2012 ruling in Commissioner of Internal Revenue v. Pilipinas Shell Petroleum Corporation (G.R. No. 188497) settles a recurring question in Philippine excise taxation: when a local oil company sells petroleum products to international carriers, who bears the excise tax burden? The answer has significant implications for manufacturers, sellers, and tax-exempt buyers alike.

The Facts of the Case

Pilipinas Shell Petroleum Corporation, a local petroleum manufacturer, filed claims for refund or tax credit with the Bureau of Internal Revenue (BIR) covering excise taxes it paid on sales and deliveries of gas and fuel oils to various international carriers during the periods October 2001 to June 2002. The total claims amounted to over P100 million.

When the BIR failed to act on these claims, Shell elevated the matter to the Court of Tax Appeals (CTA). The CTA initially ruled in Shell's favor, relying on the provision of the National Internal Revenue Code (NIRC) that exempts petroleum products sold to international carriers from excise tax. The CTA reasoned that the exemption attached to the goods themselves, making the excise tax erroneously collected and therefore refundable.

The Commissioner of Internal Revenue appealed, arguing that the exemption was granted to the international carriers as buyers, not to the manufacturers or producers of the petroleum products.

The Issue

The central question before the Supreme Court was whether a local manufacturer or producer of petroleum products is exempt from paying excise tax on products it sold to international carriers, and consequently, whether it is entitled to a refund of the excise taxes it had paid.

The Ruling

The Supreme Court reversed the CTA's decision and denied Shell's claims for refund. The Court held that the excise tax exemption under the NIRC provision on petroleum products sold to international carriers is conferred on international carriers who purchase petroleum products for their use or consumption outside the Philippines—not on the manufacturers or producers who sell those products.

Excise Tax Attaches to the Manufacturer

Under the NIRC, excise taxes attach to petroleum products once they are produced or manufactured. The tax must be paid by the manufacturer, producer, or person having possession of the goods before their removal from the place of production. This means there can be no outright exemption from excise tax payment at the point of removal, even if the products are ultimately destined for international carriers.

Distinguishing the Nature of the Exemption

The Court made a crucial distinction between two types of exemptions:

• One type exempts certain goods based on their nature and quality, without regard to who buys them.
• The other type exempts petroleum products based on who buys them—specifically, international carriers and other tax-exempt entities.

Because the exemption for petroleum products sold to international carriers focuses on the buyer's status, the exemption cannot be invoked by the manufacturer or seller. The Court applied the principle from Philippine Acetylene Co., Inc. v. Commissioner of Internal Revenue (G.R. No. L-19707, 1967): a tax exemption enjoyed by the buyer cannot be the basis of a claim for tax exemption by the manufacturer or seller.

The Nature of Excise Tax as an Indirect Tax

The Court emphasized that excise tax is an indirect tax—one that is paid by the manufacturer but can be shifted to the buyer as part of the selling price. However, because international carriers are exempt from the tax, manufacturers cannot pass on the excise tax burden to them. Instead, the manufacturer must absorb the cost.

Practical Takeaways

• Oil companies cannot claim refunds for excise taxes paid on petroleum products sold to international carriers. The exemption belongs to the carriers, not the manufacturers.
• The tax burden stays with the manufacturer. Since international carriers are exempt, oil companies must absorb the excise tax cost rather than adding it to the selling price.
• Tax refunds are strictly construed. Claims for refund are treated as claims for exemption and must be based on clear and unequivocal statutory authority. Vague inferences or equitable arguments will not suffice.
• Know the distinction in exemptions. Whether an exemption attaches to the goods themselves or to the buyer matters greatly in determining who may claim the benefit.
• Plan accordingly. Manufacturers selling to tax-exempt buyers should factor the excise tax into their pricing strategy, knowing they cannot shift this cost to exempt purchasers.
