Decoding Tax Treaties: Philippines Clarifies Most Favored Nation Clause in Royalty Taxation

The Supreme Court's 1999 decision in Commissioner of Internal Revenue v. S.C. Johnson and Son, Inc. (G.R. No. 127105) settled an important question in Philippine international tax law: when can a taxpayer invoke the "most favored nation" (MFN) clause in a tax treaty to claim a lower withholding tax rate on royalties? The case clarifies that the clause is not a simple invitation to pick the lowest rate available in any treaty—it requires that the taxes be paid under "similar circumstances."

The Dispute: Which Tax Rate Applies to Royalties?

S.C. Johnson and Son, Inc., a Philippine domestic corporation, entered into a license agreement with its U.S. parent company, S.C. Johnson and Son, USA. Under the agreement, the Philippine subsidiary paid royalties for the use of trademarks, patents, and technology. The company withheld and remitted the 25% tax on these royalty payments from July 1992 to May 1993, totaling about P1.6 million.

The company later claimed a refund of roughly P963,000, arguing that the royalties should have been taxed at only 10%. This claim was based on the MFN clause in the RP-US Tax Treaty (paragraph 2(b)(iii)), which allows the Philippines to impose the lowest rate of tax that it grants to residents of a third state on "royalties of the same kind paid under similar circumstances." The company pointed to the RP-West Germany Tax Treaty, which imposes only a 10% rate on royalties for the use of patents, trademarks, and similar property.

The Court of Tax Appeals and the Court of Appeals both sided with the taxpayer, interpreting the phrase "paid under similar circumstances" to refer to the payment of royalties, not the payment of taxes. The Commissioner of Internal Revenue appealed to the Supreme Court.

The Issue: "Paid Under Similar Circumstances"

The central question was whether the phrase "royalties of the same kind paid under similar circumstances" in the RP-US Tax Treaty referred to the circumstances of paying the royalties themselves, or to the circumstances of paying the tax on those royalties.

The taxpayer argued that since the phrase "to a resident of a third state" follows the word because the relief-from-double-taxation provisions differ materially. Therefore, the taxpayer could not invoke the 10% rate granted to German residents.

The Strict Standard for Tax Refunds

The Court also emphasized that tax refunds are in the nature of tax exemptions and must be construed strictly against the claimant. The burden of proof rests on the taxpayer claiming the exemption, who must justify the claim by the clearest grant of law. Since S.C. Johnson failed to prove that the taxes were paid under similar circumstances, its refund claim failed.

Practical Takeaways

• The MFN clause in a tax treaty is not a "race to the bottom." A taxpayer cannot simply cite a lower rate in any other Philippine tax treaty without showing that the tax treatment is comparable.
• The key comparison is the overall tax burden, including how the residence state provides relief from double taxation. A matching credit provision in one treaty can be a decisive difference.
• Taxpayers claiming treaty benefits must be prepared to prove that their situation falls squarely within the treaty's terms, including any conditions attached to concessional rates.
• The decision underscores the importance of reading treaty provisions in context and in light of their purpose, not just their literal wording.
• Claims for tax refunds are strictly construed; ambiguity will generally be resolved against the taxpayer.
