Article II
U.S. Income Tax Treaty — Technical Explanation for Protocol - 2006 · 2026-10-03 edition · updated 2026-10-04 · United States
Paragraph a) of Article II of the Protocol replaces paragraph 1 of Article 4 (Residence) of the Convention. The term "resident of a Contracting State" is defined in subparagraph a) of paragraph 1. In general, this definition incorporates the definitions of residence in U.S. and Finnish law by referring to a resident as a person who, under the laws of a Contracting State, is subject to tax therein by reason of his domicile, residence, place of management, place of incorporation or any other similar criterion. Thus, residents of the United States include aliens who are considered U.S. residents under Code section 7701(b). Subparagraph a) of paragraph 1 also specifically includes the two Contracting States, and political subdivisions, statutory bodies and local authorities of the two States, as residents for purposes of the Convention.
Certain entities that are nominally subject to tax but that in practice are rarely required to pay tax also would generally be treated as residents and therefore accorded treaty benefits. For example, a U.S. Regulated Investment Company (RIC) and a U.S. Real Estate Investment Trust (REIT) are residents of the United States for purposes of the treaty. Although the income earned by these entities normally is not subject to U.S. tax in the hands of the entity, they are taxable to the extent that they do not currently distribute their profits, and therefore may be regarded as "liable to tax." They also must satisfy a number of requirements under the Code in order to be entitled to special tax treatment.
A person who is liable to tax in a Contracting State only in respect of income from sources within that State or capital situated therein or of profits attributable to a permanent establishment in that State will not be treated as a resident of that Contracting State for purposes of the Convention. Thus, a consular official of Finland who is posted in the United States, who may be subject to U.S. tax on U.S. source investment income, but is not taxable in the United States on non-U.S. source income (see Code section 7701(b)(5)(B)), would not be considered a resident of the United States for purposes of the Convention. Similarly, an enterprise of Finland with a permanent establishment in the United States is not, by virtue of that permanent establishment, a resident of the United States. The enterprise generally is subject to

U.S. tax only with respect to its income that is attributable to the U.S. permanent establishment, not with respect to its worldwide income, as it would be if it were a U.S. resident.
Subparagraph b) of paragraph 1 contains an exception to the general rule of paragraph 1 a) that residence under internal law also determines residence under the Convention. The exception applies with respect to a U.S. citizen or alien lawfully admitted for permanent residence ( i.e., a "green card" holder). Under paragraph 1 a), a person is considered a resident of the United States for purposes of the Convention if he is liable to tax in the United States by reason of citizenship. In addition, aliens admitted to the United States for permanent residence (“green card” holders) qualify as U.S. residents under the first sentence of paragraph 1 because they are taxed by the United States as residents, regardless of where they physically reside.
Paragraph 1 b) provides that a U.S. citizen or green card holder will be treated as a resident of the United States for purposes of the Convention, and, thereby entitled to treaty benefits, only if he has a substantial presence (see section 7701(b)(3)), permanent home or habitual abode in the United States. This rule requires that the U.S. citizen or green card holder have a reasonably strong nexus with the United States.
Thus, for example, an individual resident of Mexico who is a U.S. citizen by birth, or who is a Mexican citizen and holds a U.S. green card, but who, in either case, has never lived in the United States, would not be entitled to benefits under the Convention. However, a U.S. citizen who is transferred to Mexico for two years would be entitled to benefits under the Convention if he maintains a permanent home or habitual abode in the United States.
The fact that a U.S. citizen who does not have close ties to the United States may not be treated as a U.S. resident under the Convention does not alter the application of the saving clause of paragraph 4 of Article 1 (Personal Scope) to that citizen. For example, a U.S. citizen who pursuant to the "citizen/green card holder" rule is not considered to be a resident of the United States still is taxable on his worldwide income under the generally applicable rules of the Code.
Subparagraph c) of paragraph 1 of Article 4 of the Convention provides that certain tax-exempt entities such as pension funds and charitable organizations will be regarded as residents of a Contracting State regardless of whether they are generally liable to income tax in the State where they are established. Subparagraph c) applies to legal persons organized under the laws of a Contracting State and established and maintained in that State to provide pensions or other similar benefits pursuant to a plan, or exclusively for religious, charitable, scientific, artistic, cultural, or educational purposes. Thus, a section 501(c) organization (such as a U.S. charity) that is generally exempt from tax under U.S. law is a resident of the United States for all purposes of the Convention.
Paragraph b) of Article II of the Protocol, which replaces paragraph 3 of Article 4 (Residence) of the Convention, addresses dual-residence issues for persons other than

individuals. This provision applies to persons such as trusts, estates, and corporations. If such a person is, under paragraph 1 of Article 4 of the Convention, resident in both Contracting States, the competent authorities shall seek to determine a single State of residence for such person for purposes of the Convention.
If the competent authorities do not reach an agreement on a single State of residence, that person may not claim any benefit accorded to residents of a Contracting State by the Convention. The person may, however, claim any benefits that are not limited to residents, such as those provided by paragraph 1 of Article 24 (NonDiscrimination). Thus, for example, a State cannot discriminate against a dual-resident company.
Dual resident persons also may be treated as a resident of a Contracting State for purposes other than that of obtaining benefits under the Convention. For example, if a dual resident company pays a dividend to a resident of the other Contracting State, the U.S. paying agent would withhold on that dividend at the appropriate treaty rate because reduced withholding is a benefit enjoyed by the resident of the other Contracting State, not by the dual resident company. The dual resident company that paid the dividend would, for this purpose, be treated as a resident of the United States under the Convention. In addition, information relating to dual resident companies can be exchanged under the Convention because, by its terms, Article 26 (Exchange of Information) is not limited to residents of the Contracting States.
