Excise Tax Exemptions on Petroleum Sold to International Carriers: Key Lessons from Pilipinas Shell

The Supreme Court’s June 2021 ruling in Pilipinas Shell Petroleum Corporation v. Commissioner of Internal Revenue (G.R. No. 211303) is a significant clarification of how excise tax exemptions work for petroleum products sold to international carriers. The case settles a long-standing question about who actually benefits from the tax exemption under Section 135 of the National Internal Revenue Code (NIRC), and when a manufacturer or importer can claim a refund. For businesses engaged in the sale of fuel to international airlines, understanding this decision is crucial for managing tax liabilities and refund claims.

The Facts of the Case

Pilipinas Shell Petroleum Corporation (PSPC) imported over 28 million liters of Jet A-1 fuel in early 2006 and paid excise taxes to the Bureau of Customs totaling more than P104 million. It also purchased locally over 3 million liters from Chevron Philippines, Inc., with the excise tax cost passed on as part of the purchase price. PSPC subsequently sold nearly 25 million liters of this fuel to various international carriers for consumption outside the Philippines.

When PSPC filed a claim for refund of the excise taxes paid on the fuel sold to international carriers, the Bureau of Internal Revenue failed to act on the claim. PSPC elevated the matter to the Court of Tax Appeals (CTA), which denied the refund based on an earlier 2012 ruling that Section 135(a) merely prohibited shifting the tax burden to international carriers rather than granting an exemption to manufacturers.

The Core Issue

The central question was whether PSPC, as the manufacturer and importer of petroleum products later sold to international carriers, could claim a refund of excise taxes under Section 135(a) of the NIRC. This required the Court to determine who actually benefits from the exemption—the manufacturer/importer or the international carrier purchaser.

The Supreme Court's Ruling

The Court ruled in favor of PSPC, partially granting its petition and remanding the case to the CTA for further factual determination. The ruling rested on several key principles.

Excise taxes are property taxes, not taxes on persons. The Court explained that excise taxes are levied on certain articles manufactured or imported for domestic consumption. Liability arises immediately upon importation or when goods come into existence. This means the tax attaches to the property itself, not to the persons who handle it.

The distinction between tax incidence and tax burden. In indirect taxes, the statutory taxpayer (the manufacturer or importer) bears the legal liability to pay the tax, while the economic burden may be shifted to buyers through the pricing of goods. The Court emphasized that when a seller passes on the tax to a buyer, it shifts only the economic burden, not the legal liability. The purchaser does not become the statutory taxpayer.

Section 135 grants an impersonal exemption. The Court clarified that the exemption under Section 135 applies to the petroleum products themselves, not to the enumerated persons. The wording of the provision states that "petroleum products sold to the following are exempt from excise tax," making the exemption impersonal in nature. The enumerated entities merely describe the conditions under which the exemption becomes operative.

The exemption benefits the statutory taxpayer. Since international carriers are not statutory taxpayers for excise tax purposes, they cannot be the beneficiaries of the exemption. Instead, the exemption must benefit the manufacturers or importers who actually bear the legal liability for the tax. Once petroleum products are sold to international carriers, the exemption takes effect, and any excise taxes previously paid become erroneously collected and subject to refund.

Limits on the Refund

The Court imposed an important limitation: PSPC could only claim a refund for the fuel it imported itself. For the fuel purchased from Chevron, PSPC merely bore the economic burden of the tax passed on by Chevron. Since PSPC was not the statutory taxpayer for that fuel, it could not claim the refund. The case was remanded to the CTA to determine the exact composition of the fuel sold to international carriers.

Practical Takeaways

• Manufacturers and importers, not buyers, benefit from the Section 135 exemption. If your company imports or manufactures petroleum products and sells them to international carriers, you may be entitled to a refund of excise taxes previously paid.

• The exemption is impersonal. It attaches to the petroleum products, not to the persons enumerated in Section 135. The exemption becomes operative when the products are sold to international carriers or other exempt entities.

• Only statutory taxpayers can claim refunds. If you merely purchased fuel from another supplier and the excise tax was passed on to you as part of the price, you cannot claim the refund—even if you later sell the fuel to international carriers.

• Document your sources. To successfully claim a refund, you must be able to prove which fuel was directly imported or manufactured by you versus purchased from other suppliers. The Court remanded this case because the records did not clearly show this breakdown.

• Timing matters. The exemption takes effect upon the sale to international carriers. Any excise taxes paid before that sale become erroneously collected and may be recovered under Sections 204 and 229 of the NIRC.
