Article 24 (Non-Discrimination)
U.S. Income Tax Treaty — Technical Explanation - 2003 · 2026-10-03 edition · updated 2026-10-04 · United States
This Article ensures that nationals of a Contracting State, in the case of paragraph 1, and residents of a Contracting State, in the case of paragraphs 2 through 4, will not be subject, directly or indirectly, to discriminatory taxation in the other Contracting State. For this purpose, non-discrimination means providing national treatment. Not all differences in tax treatment, either as between nationals of the two Contracting States, or between residents of the two Contracting States, are violations of this national treatment standard. Rather, the national
94
treatment obligation of this Article applies only if the nationals or residents of the two Contracting States are comparably situated.
Each of the relevant paragraphs of the Article provides that two persons that are comparably situated must be treated similarly. Although the actual words differ from paragraph to paragraph ( e.g., paragraph 1 refers to two nationals “in the same circumstances,” paragraph 2 refers to two enterprises “carrying on the same activities” and paragraph 4 refers to two enterprises that are “similar”), the common underlying premise is that if the difference in treatment is directly related to a tax-relevant difference in the situations of the domestic and foreign persons being compared, that difference is not to be treated as discriminatory (i.e ., if one person is taxable in a Contracting State on worldwide income and the other is not, or tax may be collectible from one person at a later stage, but not from the other, distinctions in treatment would be justified under paragraph 1). Other examples of such factors that can lead to nondiscriminatory differences in treatment are noted in the discussions of each paragraph.
The operative paragraphs of the Article also use different language to identify the kinds of differences in taxation treatment that will be considered discriminatory. For example, paragraphs 1 and 4 speak of “any taxation or any requirement connected therewith which is other or more burdensome,” while paragraph 2 specifies that a tax “shall not be less favorably levied.” Regardless of these differences in language, only differences in tax treatment that materially disadvantage the foreign person relative to the domestic person are properly the subject of the Article.
Paragraph 1
Paragraph 1 provides that a national of one Contracting State may not be subject to taxation or connected requirements in the other Contracting State that are different from, or more burdensome than, the taxes and connected requirements imposed upon a national of that other Contracting State in the same circumstances. As noted above, whether or not the two persons are both taxable on worldwide income is a significant circumstance for this purpose. The 1992 revision of the OECD Model added, after the words “in the same circumstances,” the phrase “in particular with respect to residence,” reflecting the fact that under most countries' laws residents are taxable on worldwide income and nonresidents are not. Since in the United States nonresident citizens are also taxable on worldwide income the Convention, like the U.S. Model, expands the phrase to refer, not to residence, but to taxation on worldwide income.
A national of a Contracting State is afforded protection under this paragraph even if the national is not a resident of either Contracting State. Thus, a U.S. citizen who is resident in a third country is entitled, under this paragraph, to the same treatment in Japan as a citizen of Japan who is in similar circumstances (i.e., who is resident in a third State). The term “national” in relation to a Contracting State is defined in subparagraph 1(j) of Article 3. The term includes both individuals and juridical persons.
Paragraph 2
Paragraph 2 of the Article, like the comparable paragraphs in the U.S. and OECD Models, provides that a Contracting State may not tax a permanent establishment of an enterprise
95
of the other Contracting State less favorably than an enterprise of that first-mentioned State that is carrying on the same activities.
The fact that a U.S. permanent establishment of an enterprise of Japan is subject to U.S. tax only on income that is attributable to the permanent establishment, while a U.S. corporation engaged in the same activities is taxable on its worldwide income is not, in itself, a sufficient difference to deny national treatment to the permanent establishment. There are cases, however, where the two enterprises would not be similarly situated and differences in treatment may be warranted. For instance, it would not be a violation of the non-discrimination protection of paragraph 2 to require the foreign enterprise to provide information in a reasonable manner that may be different from the information requirements imposed on a resident enterprise, because information may not be as readily available to the Internal Revenue Service from a foreign as from a domestic enterprise. Similarly, it would not be a violation of paragraph 2 to impose penalties on persons who fail to comply with such a requirement (see, e.g., sections 874(a) and 882(c)(2)). Further, a determination that income and expenses have been attributed or allocated to a permanent establishment in conformity with the principles of Article 7 (Business Profits) implies that the attribution or allocation was not discriminatory.
Section 1446 of the Code imposes on any partnership with income that is effectively connected with a U.S. trade or business the obligation to withhold tax on amounts allocable to a foreign partner. In the context of the Convention, this obligation applies with respect to a share of the partnership income of a partner resident in Japan, and attributable to a U.S. permanent establishment. There is no similar obligation with respect to the distributive shares of U.S. resident partners. It is understood, however, that this distinction is not a form of discrimination within the meaning of paragraph 2 of the Article. No distinction is made between U.S. and nonU.S. partnerships, since the law requires that partnerships of both U.S. and non-U.S. domicile withhold tax in respect of the partnership shares of non-U.S. partners. Furthermore, in distinguishing between U.S. and non-U.S. partners, the requirement to withhold on the non-U.S. but not the U.S. partner's share is not discriminatory taxation, but, like other withholding on nonresident aliens, is merely a reasonable method for the collection of tax from persons who are not continually present in the United States, and as to whom it otherwise may be difficult for the United States to enforce its tax jurisdiction. If tax has been over-withheld, the partner can, as in other cases of over-withholding, file for a refund.
Paragraph 2 also provides that a Contracting State is not obligated under this paragraph to grant to a resident of the other Contracting State any personal allowances, reliefs, and reductions for tax purposes that it grants to its own residents on account of their civil status or family responsibilities. Thus, if a sole proprietor who is a resident of Japan has a permanent establishment in the United States, in assessing income tax on the profits attributable to the permanent establishment, the United States is not obligated to allow to the resident of Japan the personal allowances for himself and his family that he would be permitted to take if the permanent establishment were a sole proprietorship owned and operated by a U.S. resident, despite the fact that the individual income tax rates would apply.

Paragraph 3
Paragraph 3 prohibits discrimination in the allowance of deductions. When a resident of a Contracting State pays interest, royalties or other disbursements to a resident of the other Contracting State, the first-mentioned Contracting State must allow a deduction for those payments in computing the taxable profits of the resident as if the payment had been made under the same conditions to a resident of the first-mentioned Contracting State. Paragraph 3, however, does not require a Contracting State to give non-residents more favorable treatment than it gives to its own residents. Consequently, a Contracting State does not have to allow nonresidents a deduction for items that are not deductible under its domestic law (for example, expenses of a capital nature).
The term “other disbursements” is understood to include a reasonable allocation of executive and general administrative expenses, research and development expenses and other expenses incurred for the benefit of a group of related persons that includes the person incurring the expense.
The opening part of the paragraph lists provisions of the Convention where the protection it gives for deductions does not apply. These are concerned with transactions involving potential abuse, where it is appropriate for the Contracting States to continue to apply their anti-avoidance safeguards. The paragraph carves out from its coverage the special relationship paragraphs at paragraph 8 of Article 11 (Interest), paragraph 4 of Article 12 (Royalties) and paragraph 3 of Article 21 (Other Income). Neither State is forced to apply the non-discrimination principle in such cases. The exception with respect to paragraph 8 of Article 11 would include the denial or deferral of certain interest deductions under Code section 163(j).
Paragraph 3 also provides that any debts of a resident or enterprise of a Contracting State to a resident of the other Contracting State are deductible in the first-mentioned Contracting State for computing the taxable capital of the resident under the same conditions as if the debt had been contracted to a resident of the first-mentioned Contracting State. Even though, for general purposes, the Convention covers only income taxes, under paragraph 6 of this Article, the nondiscrimination provisions apply to all taxes levied in both Contracting States, at all levels of government. Thus, this provision may be relevant for both Contracting States as it would apply to property taxes imposed at the local level.
Paragraph 4
Paragraph 4 requires that a Contracting State not impose more burdensome taxation or connected requirements on an enterprise of that Contracting State that is wholly or partly owned or controlled, directly or indirectly, by one or more residents of the other Contracting State than the taxation or connected requirements that it imposes on other similar enterprises of that firstmentioned Contracting State. For this purpose it is understood that “similar” refers to similar activities or ownership of the enterprise.
This rule, like all non-discrimination provisions, does not prohibit differing treatment of entities that are in differing circumstances. Rather, a protected enterprise is only required to be treated in the same manner as other enterprises that, from the point of view of the application of
97
the tax law, are in substantially similar circumstances both in law and in fact. The taxation of a distributing corporation under section 367(e) on an applicable distribution to foreign shareholders does not violate paragraph 4 of the Article because a foreign-owned corporation is not similar to a domestically-owned corporation that is accorded nonrecognition treatment under sections 337 and 355.
For the reasons given above in connection with the discussion of paragraph 2 of the Article, it is also understood that the provision in section 1446 of the Code for withholding of tax on non-U.S. partners does not violate paragraph 4 of the Article.
It is further understood that the ineligibility of a U.S. corporation with nonresident alien shareholders to make an election to be an “S” corporation does not violate paragraph 4 of the Article. If a corporation elects to be an S corporation (requiring 75 or fewer shareholders), it is generally not subject to income tax and the shareholders take into account their pro rata shares of the corporation's items of income, loss, deduction or credit. (The purpose of the provision is to allow an individual or small group of individuals to conduct business in corporate form while paying taxes at individual rates as if the business were conducted directly.) A nonresident alien does not pay U.S. tax on a net basis, and, thus, does not generally take into account items of loss, deduction or credit. Thus, the S corporation provisions do not exclude corporations with nonresident alien shareholders because such shareholders are foreign, but only because they are not net-basis taxpayers. Similarly, the provisions exclude corporations with other types of shareholders where the purpose of the provisions cannot be fulfilled or their mechanics implemented. For example, corporations with corporate shareholders are excluded because the purpose of the provision to permit individuals to conduct a business in corporate form at individual tax rates would not be furthered by their inclusion.
Paragraph 5
Paragraph 5 of the Article confirms that no provision of the Article will prevent either Contracting State from imposing the branch-level taxes described in paragraph 9 of Article 10 (Dividends) and paragraph 10 of Article 11 (Interest).
Paragraph 6
As noted above, notwithstanding the specification in Article 2 (Taxes Covered) and subparagraph (d) of paragraph 1 of Article 3 (General Definitions) of taxes covered by the Convention for general purposes, for purposes of providing non-discrimination protection this Article applies to taxes of every kind and description imposed by a Contracting State or a political subdivision or local authority thereof. Customs duties are not considered to be taxes for this purpose.
