UNITED STATES MODEL TECHNICAL EXPLANATION ACCOMPANYING THE UNITED STATES MODEL INCOME TAX CONVENTION OF NOVEMBER 15, 2006

Article 22 and the anti-abuse provisions of domestic law complement each other, as

U.S. Income Tax Treaty — Technical Explanation -2006 · 2026-10-03 edition · updated 2026-10-04 · United States

Article 22 effectively determines whether an entity has a sufficient nexus to the Contracting State to be treated as a resident for treaty purposes, while domestic anti-abuse provisions ( e.g., business purpose, substance-over-form, step transaction or conduit principles) determine whether a particular transaction should be recast in accordance with its substance. Thus, internal law principles of the source Contracting State may be applied to identify the beneficial owner of an item of income, and Article 22 then will be applied to the beneficial owner to determine if that person is entitled to the benefits of the Convention with respect to such income.

Paragraph 2

Paragraph 2 has six subparagraphs, each of which describes a category of residents that are entitled to all benefits of the Convention.

It is intended that the provisions of paragraph 2 will be self executing. Unlike the provisions of paragraph 4, discussed below, claiming benefits under paragraph 2 does not require advance competent authority ruling or approval. The tax authorities may, of course, on review, determine that the taxpayer has improperly interpreted the paragraph and is not entitled to the benefits claimed.

Individuals -- Subparagraph 2(a)

Subparagraph (a) provides that individual residents of a Contracting State will be entitled to all treaty benefits. If such an individual receives income as a nominee on behalf of a third country resident, benefits may be denied under the respective articles of the Convention by the requirement that the beneficial owner of the income be a resident of a Contracting State.

Governments -- Subparagraph 2(b)

Subparagraph (b) provides that the Contracting States and any political subdivision or local authority thereof will be entitled to all benefits of the Convention.

Publicly-Traded Corporations -- Subparagraph 2(c)(i)

Subparagraph (c) applies to two categories of companies: publicly traded companies and subsidiaries of publicly traded companies. A company resident in a Contracting State is entitled to all the benefits of the Convention under clause (i) of subparagraph (c) if the principal class of

2006 U.S. Model Technical Explanation

  • 65

its shares, and any disproportionate class of shares, is regularly traded on one or more recognized stock exchanges and the company satisfies at least one of the following additional requirements: first, the company’s principal class of shares is primarily traded on one or more recognized stock exchanges located in the Contracting State of which the company is a resident; or, second, the company’s primary place of management and control is in its State of residence.

The term “recognized stock exchange” is defined in subparagraph (a) of paragraph 5. It includes (i) the NASDAQ System and any stock exchange registered with the Securities and Exchange Commission as a national securities exchange for purposes of the Securities Exchange Act of 1934; (ii) [certain exchanges located in the other Contracting State]; and (iii) any other stock exchange agreed upon by the competent authorities of the Contracting States.

If a company has only one class of shares, it is only necessary to consider whether the shares of that class meet the relevant trading requirements. If the company has more than one class of shares, it is necessary as an initial matter to determine which class or classes constitute the "principal class of shares". The term “principal class of shares” is defined in subparagraph (b) of paragraph 5 to mean the ordinary or common shares of the company representing the majority of the aggregate voting power and value of the company. If the company does not have a class of ordinary or common shares representing the majority of the aggregate voting power and value of the company, then the “principal class of shares” is that class or any combination of classes of shares that represents, in the aggregate, a majority of the voting power and value of the company. Although in a particular case involving a company with several classes of shares it is conceivable that more than one group of classes could be identified that account for more than 50% of the shares, it is only necessary for one such group to satisfy the requirements of this subparagraph in order for the company to be entitled to benefits. Benefits would not be denied to the company even if a second, non-qualifying, group of shares with more than half of the company's voting power and value could be identified.

A company whose principal class of shares is regularly traded on a recognized stock exchange will nevertheless not qualify for benefits under subparagraph (c) of paragraph 2 if it has a disproportionate class of shares that is not regularly traded on a recognized stock exchange. The term “disproportionate class of shares” is defined in subparagraph (c) of paragraph 5. A company has a disproportionate class of shares if it has outstanding a class of shares which is subject to terms or other arrangements that entitle the holder to a larger portion of the company’s income, profit, or gain in the other Contracting State than that to which the holder would be entitled in the absence of such terms or arrangements. Thus, for example, a company resident in the other Contracting State meets the test of subparagraph (c) of paragraph 5 if it has outstanding a class of “tracking stock” that pays dividends based upon a formula that approximates the company’s return on its assets employed in the United States.

The following example illustrates this result.

Example. OCo is a corporation resident in the other Contracting State. OCo has two classes of shares: Common and Preferred. The Common shares are listed and regularly traded on the principal stock exchange of the other Contracting State. The Preferred shares have no voting rights and are entitled to receive dividends equal in amount to interest payments that OCo

  • 66

receives from unrelated borrowers in the United States. The Preferred shares are owned entirely by a single investor that is a resident of a country with which the United States does not have a tax treaty. The Common shares account for more than 50 percent of the value of OCo and for 100 percent of the voting power. Because the owner of the Preferred shares is entitled to receive payments corresponding to the U.S. source interest income earned by OCo, the Preferred shares are a disproportionate class of shares. Because the Preferred shares are not regularly traded on a recognized stock exchange, OCo will not qualify for benefits under subparagraph (c) of paragraph 2.

The term "regularly traded" is not defined in the Convention. In accordance with paragraph 2 of Article 3 (General Definitions), this term will be defined by reference to the domestic tax laws of the State from which treaty benefits are sought, generally the source State. In the case of the United States, this term is understood to have the meaning it has under Treas. Reg. section 1.884-5(d)(4)(i)(B), relating to the branch tax provisions of the Code. Under these regulations, a class of shares is considered to be "regularly traded" if two requirements are met: trades in the class of shares are made in more than de minimis quantities on at least 60 days during the taxable year, and the aggregate number of shares in the class traded during the year is at least 10 percent of the average number of shares outstanding during the year. Sections 1.8845(d)(4)(i)(A), (ii) and (iii) will not be taken into account for purposes of defining the term "regularly traded" under the Convention.

The regular trading requirement can be met by trading on any recognized exchange or exchanges located in either State. Trading on one or more recognized stock exchanges may be aggregated for purposes of this requirement. Thus, a U.S. company could satisfy the regularly traded requirement through trading, in whole or in part, on a recognized stock exchange located in the other Contracting State. Authorized but unissued shares are not considered for purposes of this test.

The term “primarily traded” is not defined in the Convention. In accordance with paragraph 2 of Article 3 (General Definitions), this term will have the meaning it has under the laws of the State concerning the taxes to which the Convention applies, generally the source State. In the case of the United States, this term is understood to have the meaning it has under Treas. Reg. section 1.884-5(d)(3), relating to the branch tax provisions of the Code. Accordingly, stock of a corporation is “primarily traded” if the number of shares in the company’s principal class of shares that are traded during the taxable year on all recognized stock exchanges in the Contracting State of which the company is a resident exceeds the number of shares in the company’s principal class of shares that are traded during that year on established securities markets in any other single foreign country.

A company whose principal class of shares is regularly traded on a recognized exchange but cannot meet the primarily traded test may claim treaty benefits if its primary place of management and control is in its country of residence. This test should be distinguished from the “place of effective management” test which is used in the OECD Model and by many other countries to establish residence. In some cases, the place of effective management test has been interpreted to mean the place where the board of directors meets. By contrast, the primary place

2006 U.S. Model Technical Explanation

  • 67

of management and control test looks to where day-to-day responsibility for the management of the company (and its subsidiaries) is exercised. The company’s primary place of management and control will be located in the State in which the company is a resident only if the executive officers and senior management employees exercise day-to-day responsibility for more of the strategic, financial and operational policy decision making for the company (including direct and indirect subsidiaries) in that State than in the other State or any third state, and the staff that support the management in making those decisions are also based in that State. Thus, the test looks to the overall activities of the relevant persons to see where those activities are conducted. In most cases, it will be a necessary, but not a sufficient, condition that the headquarters of the company (that is, the place at which the CEO and other top executives normally are based) be located in the Contracting State of which the company is a resident.

To apply the test, it will be necessary to determine which persons are to be considered “executive officers and senior management employees”. In most cases, it will not be necessary to look beyond the executives who are members of the Board of Directors (the “inside directors”) in the case of a U.S. company or the members of the [ ] in the case of the other Contracting State. That will not always be the case, however; in fact, the relevant persons may be employees of subsidiaries if those persons make the strategic, financial and operational policy decisions. Moreover, it would be necessary to take into account any special voting arrangements that result in certain board members making certain decisions without the participation of other board members.

Subsidiaries of Publicly-Traded Corporations -- Subparagraph 2(c)(ii)

A company resident in a Contracting State is entitled to all the benefits of the Convention under clause (ii) of subparagraph (c) of paragraph 2 if five or fewer publicly traded companies described in clause (i) are the direct or indirect owners of at least 50 percent of the aggregate vote and value of the company’s shares (and at least 50 percent of any disproportionate class of shares). If the publicly-traded companies are indirect owners, however, each of the intermediate companies must be a resident of one of the Contracting States.

Thus, for example, a company that is a resident of the other Contracting State, all the shares of which are owned by another company that is a resident of that State, would qualify for benefits under the Convention if the principal class of shares (and any disproportionate classes of shares) of the parent company are regularly and primarily traded on a recognized stock exchange in that Contracting State. However, such a subsidiary would not qualify for benefits under clause (ii) if the publicly traded parent company were a resident of a third state, for example, and not a resident of the United States or the other Contracting State. Furthermore, if a parent company in the other Contracting State indirectly owned the bottom-tier company through a chain of subsidiaries, each such subsidiary in the chain, as an intermediate owner, must be a resident of the United States or the other Contracting State in order for the subsidiary to meet the test in clause (ii).

Tax Exempt Organizations -- Subparagraph 2(d)

Subparagraph 2(d) provides rules by which the tax exempt organizations described in paragraph 2 of Article 4 (Resident) will be entitled to all the benefits of the Convention. A pension fund will qualify for benefits if more than fifty percent of the beneficiaries, members or participants of the organization are individuals resident in either Contracting State. For purposes of this provision, the term "beneficiaries" should be understood to refer to the persons receiving benefits from the organization. On the other hand, a tax-exempt organization other than a pension fund automatically qualifies for benefits, without regard to the residence of its beneficiaries or members. Entities qualifying under this rule generally are those that are exempt from tax in their State of residence and that are organized and operated exclusively to fulfill religious, charitable, scientific, artistic, cultural, or educational purposes.

Ownership/Base Erosion -- Subparagraph 2(e)

Subparagraph 2(e) provides an additional method to qualify for treaty benefits that applies to any form of legal entity that is a resident of a Contracting State. The test provided in subparagraph (e), the so-called ownership and base erosion test, is a two-part test. Both prongs of the test must be satisfied for the resident to be entitled to treaty benefits under subparagraph 2(e).

The ownership prong of the test, under clause (i), requires that 50 percent or more of each class of shares or other beneficial interests in the person is owned, directly or indirectly, on at least half the days of the person’s taxable year by persons who are residents of the Contracting State of which that person is a resident and that are themselves entitled to treaty benefits under subparagraphs (a), (b), (d) or clause (i) of subparagraph (c) of paragraph 2. In the case of indirect owners, however, each of the intermediate owners must be a resident of that Contracting State.

Trusts may be entitled to benefits under this provision if they are treated as residents under Article 4 (Residence) and they otherwise satisfy the requirements of this subparagraph. For purposes of this subparagraph, the beneficial interests in a trust will be considered to be owned by its beneficiaries in proportion to each beneficiary's actuarial interest in the trust. The interest of a remainder beneficiary will be equal to 100 percent less the aggregate percentages held by income beneficiaries. A beneficiary's interest in a trust will not be considered to be owned by a person entitled to benefits under the other provisions of paragraph 2 if it is not possible to determine the beneficiary's actuarial interest. Consequently, if it is not possible to determine the actuarial interest of the beneficiaries in a trust, the ownership test under clause i) cannot be satisfied, unless all possible beneficiaries are persons entitled to benefits under the other subparagraphs of paragraph 2.

The base erosion prong of clause (ii) of subparagraph (e) is satisfied with respect to a person if less than 50 percent of the person’s gross income for the taxable year, as determined under the tax law in the person’s State of residence, is paid or accrued to persons who are not residents of either Contracting State entitled to benefits under subparagraphs (a), (b), (d) or clause (i) of subparagraph (c) of paragraph 2, in the form of payments deductible for tax

2006 U.S. Model Technical Explanation

  • 69

purposes in the payer’s State of residence. These amounts do not include arm’s-length payments in the ordinary course of business for services or tangible property. To the extent they are deductible from the taxable base, trust distributions are deductible payments. However, depreciation and amortization deductions, which do not represent payments or accruals to other persons, are disregarded for this purpose.

Paragraph 3

Paragraph 3 sets forth an alternative test under which a resident of a Contracting State may receive treaty benefits with respect to certain items of income that are connected to an active trade or business conducted in its State of residence. A resident of a Contracting State may qualify for benefits under paragraph 3 whether or not it also qualifies under paragraph 2.

Subparagraph (a) sets forth the general rule that a resident of a Contracting State engaged in the active conduct of a trade or business in that State may obtain the benefits of the Convention with respect to an item of income derived in the other Contracting State. The item of income, however, must be derived in connection with or incidental to that trade or business.

The term “trade or business” is not defined in the Convention. Pursuant to paragraph 2 of Article 3 (General Definitions), when determining whether a resident of the other Contracting State is entitled to the benefits of the Convention under paragraph 3 of this Article with respect to an item of income derived from sources within the United States, the United States will ascribe to this term the meaning that it has under the law of the United States. Accordingly, the U.S. competent authority will refer to the regulations issued under section 367(a) for the definition of the term “trade or business.” In general, therefore, a trade or business will be considered to be a specific unified group of activities that constitute or could constitute an independent economic enterprise carried on for profit. Furthermore, a corporation generally will be considered to carry on a trade or business only if the officers and employees of the corporation conduct substantial managerial and operational activities.

The business of making or managing investments for the resident’s own account will be considered to be a trade or business only when part of banking, insurance or securities activities conducted by a bank, an insurance company, or a registered securities dealer. Such activities conducted by a person other than a bank, insurance company or registered securities dealer will not be considered to be the conduct of an active trade or business, nor would they be considered to be the conduct of an active trade or business if conducted by a bank, insurance company or registered securities dealer but not as part of the company’s banking, insurance or dealer business. Because a headquarters operation is in the business of managing investments, a company that functions solely as a headquarters company will not be considered to be engaged in an active trade or business for purposes of paragraph 3.

An item of income is derived in connection with a trade or business if the incomeproducing activity in the State of source is a line of business that “forms a part of” or is “complementary” to the trade or business conducted in the State of residence by the income recipient.

2006 U.S. Model Technical Explanation

A business activity generally will be considered to form part of a business activity conducted in the State of source if the two activities involve the design, manufacture or sale of the same products or type of products, or the provision of similar services. The line of business in the State of residence may be upstream, downstream, or parallel to the activity conducted in the State of source. Thus, the line of business may provide inputs for a manufacturing process that occurs in the State of source, may sell the output of that manufacturing process, or simply may sell the same sorts of products that are being sold by the trade or business carried on in the State of source.

Example 1. USCo is a corporation resident in the United States. USCo is engaged in an active manufacturing business in the United States. USCo owns 100 percent of the shares of FCo, a corporation resident in the other Contracting State. FCo distributes USCo products in the other Contracting State. Since the business activities conducted by the two corporations involve the same products, FCo's distribution business is considered to form a part of USCo's manufacturing business.

Example 2. The facts are the same as in Example 1, except that USCo does not manufacture. Rather, USCo operates a large research and development facility in the United States that licenses intellectual property to affiliates worldwide, including FCo. FCo and other USCo affiliates then manufacture and market the USCo-designed products in their respective markets. Since the activities conducted by FCo and USCo involve the same product lines, these activities are considered to form a part of the same trade or business.

For two activities to be considered to be “complementary,” the activities need not relate to the same types of products or services, but they should be part of the same overall industry and be related in the sense that the success or failure of one activity will tend to result in success or failure for the other. Where more than one trade or business is conducted in the State of source and only one of the trades or businesses forms a part of or is complementary to a trade or business conducted in the State of residence, it is necessary to identify the trade or business to which an item of income is attributable. Royalties generally will be considered to be derived in connection with the trade or business to which the underlying intangible property is attributable. Dividends will be deemed to be derived first out of earnings and profits of the treaty-benefited trade or business, and then out of other earnings and profits. Interest income may be allocated under any reasonable method consistently applied. A method that conforms to U.S. principles for expense allocation will be considered a reasonable method.

Example 3. Americair is a corporation resident in the United States that operates an international airline. FSub is a wholly-owned subsidiary of Americair resident in the other Contracting State. FSub operates a chain of hotels in the other Contracting State that are located near airports served by Americair flights. Americair frequently sells tour packages that include air travel to the other Contracting State and lodging at FSub hotels. Although both companies are engaged in the active conduct of a trade or business, the businesses of operating a chain of hotels and operating an airline are distinct trades or businesses. Therefore FSub's business does not form a part of Americair's business. However, FSub's business is considered to be

2006 U.S. Model Technical Explanation

  • 71

complementary to Americair's business because they are part of the same overall industry (travel) and the links between their operations tend to make them interdependent.

Example 4. The facts are the same as in Example 3, except that FSub owns an office building in the other Contracting State instead of a hotel chain. No part of Americair's business is conducted through the office building. FSub's business is not considered to form a part of or to be complementary to Americair's business. They are engaged in distinct trades or businesses in separate industries, and there is no economic dependence between the two operations.

Example 5. USFlower is a corporation resident in the United States. USFlower produces and sells flowers in the United States and other countries. USFlower owns all the shares of ForHolding, a corporation resident in the other Contracting State. ForHolding is a holding company that is not engaged in a trade or business. ForHolding owns all the shares of three corporations that are resident in the other Contracting State: ForFlower, ForLawn, and ForFish. ForFlower distributes USFlower flowers under the USFlower trademark in the other State. ForLawn markets a line of lawn care products in the other State under the USFlower trademark. In addition to being sold under the same trademark, ForLawn and ForFlower products are sold in the same stores and sales of each company's products tend to generate increased sales of the other's products. ForFish imports fish from the United States and distributes it to fish wholesalers in the other State. For purposes of paragraph 3, the business of ForFlower forms a part of the business of USFlower, the business of ForLawn is complementary to the business of USFlower, and the business of ForFish is neither part of nor complementary to that of USFlower.

An item of income derived from the State of source is “incidental to” the trade or business carried on in the State of residence if production of the item facilitates the conduct of the trade or business in the State of residence. An example of incidental income is the temporary investment of working capital of a person in the State of residence in securities issued by persons in the State of source.

Subparagraph (b) of paragraph 3 states a further condition to the general rule in subparagraph (a) in cases where the trade or business generating the item of income in question is carried on either by the person deriving the income or by any associated enterprises. Subparagraph (b) states that the trade or business carried on in the State of residence, under these circumstances, must be substantial in relation to the activity in the State of source. The substantiality requirement is intended to prevent a narrow case of treaty-shopping abuses in which a company attempts to qualify for benefits by engaging in de minimis connected business activities in the treaty country in which it is resident ( i.e., activities that have little economic cost or effect with respect to the company business as a whole).

The determination of substantiality is made based upon all the facts and circumstances and takes into account the comparative sizes of the trades or businesses in each Contracting State the nature of the activities performed in each Contracting State, and the relative contributions made to that trade or business in each Contracting State. In any case, in making each determination or comparison, due regard will be given to the relative sizes of the economies in the two Contracting States.

2006 U.S. Model Technical Explanation

  • 72

The determination in subparagraph (b) also is made separately for each item of income derived from the State of source. It therefore is possible that a person would be entitled to the benefits of the Convention with respect to one item of income but not with respect to another. If a resident of a Contracting State is entitled to treaty benefits with respect to a particular item of income under paragraph 3, the resident is entitled to all benefits of the Convention insofar as they affect the taxation of that item of income in the State of source.

The application of the substantiality requirement only to income from related parties focuses only on potential abuse cases, and does not hamper certain other kinds of non-abusive activities, even though the income recipient resident in a Contracting State may be very small in relation to the entity generating income in the other Contracting State. For example, if a small U.S. research firm develops a process that it licenses to a very large, unrelated, pharmaceutical manufacturer in the other Contracting State, the size of the U.S. research firm would not have to be tested against the size of the manufacturer. Similarly, a small U.S. bank that makes a loan to a very large unrelated company operating a business in the other Contracting State would not have to pass a substantiality test to receive treaty benefits under Paragraph 3.

Subparagraph (c) of paragraph 3 provides special attribution rules for purposes of applying the substantive rules of subparagraphs (a) and (b). Thus, these rules apply for purposes of determining whether a person meets the requirement in subparagraph (a) that it be engaged in the active conduct of a trade or business and that the item of income is derived in connection with that active trade or business, and for making the comparison required by the "substantiality" requirement in subparagraph (b). Subparagraph (c) attributes to a person activities conducted by persons “connected” to such person. A person (“X”) is connected to another person (“Y”) if X possesses 50 percent or more of the beneficial interest in Y (or if Y possesses 50 percent or more of the beneficial interest in X). For this purpose, X is connected to a company if X owns shares representing fifty percent or more of the aggregate voting power and value of the company or fifty percent or more of the beneficial equity interest in the company. X also is connected to Y if a third person possesses fifty percent or more of the beneficial interest in both X and Y. For this purpose, if X or Y is a company, the threshold relationship with respect to such company or companies is fifty percent or more of the aggregate voting power and value or fifty percent or more of the beneficial equity interest. Finally, X is connected to Y if, based upon all the facts and circumstances, X controls Y, Y controls X, or X and Y are controlled by the same person or persons.

Paragraph 4

Paragraph 4 provides that a resident of one of the States that is not entitled to the benefits of the Convention as a result of paragraphs 1 through 3 still may be granted benefits under the Convention at the discretion of the competent authority of the State from which benefits are claimed. In making determinations under paragraph 4, that competent authority will take into account as its guideline whether the establishment, acquisition, or maintenance of the person seeking benefits under the Convention, or the conduct of such person’s operations, has or had as one of its principal purposes the obtaining of benefits under the Convention. Benefits will not be granted, however, solely because a company was established prior to the effective date of a

2006 U.S. Model Technical Explanation

  • 73

treaty or protocol. In that case a company would still be required to establish to the satisfaction of the Competent Authority clear non-tax business reasons for its formation in a Contracting State, or that the allowance of benefits would not otherwise be contrary to the purposes of the treaty. Thus, persons that establish operations in one of the States with a principal purpose of obtaining the benefits of the Convention ordinarily will not be granted relief under paragraph 4.

The competent authority's discretion is quite broad. It may grant all of the benefits of the Convention to the taxpayer making the request, or it may grant only certain benefits. For instance, it may grant benefits only with respect to a particular item of income in a manner similar to paragraph 3. Further, the competent authority may establish conditions, such as setting time limits on the duration of any relief granted.

For purposes of implementing paragraph 4, a taxpayer will be permitted to present his case to the relevant competent authority for an advance determination based on the facts. In these circumstances, it is also expected that, if the competent authority determines that benefits are to be allowed, they will be allowed retroactively to the time of entry into force of the relevant treaty provision or the establishment of the structure in question, whichever is later.

Finally, there may be cases in which a resident of a Contracting State may apply for discretionary relief to the competent authority of his State of residence. This would arise, for example, if the benefit it is claiming is provided by the residence country, and not by the source country. So, for example, if a company that is a resident of the United States would like to claim the benefit of the re-sourcing rule of paragraph 3 of Article 23, but it does not meet any of the objective tests of paragraphs 2 and 3, it may apply to the U.S. competent authority for discretionary relief.

Paragraph 5

Paragraph 5 defines several key terms for purposes of Article 22. Each of the defined terms is discussed above in the context in which it is used.
