The income tax convention between the United States and the Swiss Confederation, signed May 24, 1951, and proclaimed by the President of the United States on October 1, 1951, subject to the understanding expressed in the protocol of exchange, referred to in this part as the convention, provides as follows, effective for taxable years beginning on or after January 1, 1951:

(a) General. The Internal Revenue Code of 1954 provides in part as follows:

(b) Internal Revenue Code of 1939. Any reference in §§ 509.101 to 509.122 to any provision of the Internal Revenue Code of 1954 shall, where applicable, be deemed also to refer to the corresponding provision of the Internal Revenue Code of 1939.

(c) Effective date of regulations. Pursuant to sections 894 and 7805 of the Internal Revenue Code of 1954, Article XIX of the convention, and other provisions of the internal revenue laws, §§ 509.101 to 509.122 are hereby prescribed effective for taxable years beginning on or after January 1, 1951. All regulations inconsistent herewith are modified accordingly.

(a) Purposes of convention. The primary purposes of the convention, to be accomplished on a reciprocal basis, are to avoid double taxation upon certain items of income derived from sources in one country by residents or corporations or other entities of the other country and to provide for administrative cooperation between the competent tax authorities of the two countries looking to the avoidance of double taxation and the prevention of fiscal evasion.

(b) Exemption from United States tax. The following items of income from sources within the United States are exempt from United States tax for taxable years beginning on or after January 1, 1951, subject to the respective articles of the convention:

(1) Industrial and commercial profits of a Swiss enterprise having no permanent establishment in the United States (Article III);

(2) Income derived by a Swiss enterprise from the operation of ships or aircraft registered in Switzerland (Article V);

(3) Patent and copyright royalties, and other like amounts, including motion picture film rentals, derived by a nonresident alien who is a resident of Switzerland, or by a Swiss corporation or other entity, if such alien, corporation, or other entity has no permanent establishment in the United States (Article VIII);

(4) Compensation, subject to certain limitations, for personal services performed in the United States by a nonresident alien individual who is a resident of Switzerland (Article X);

(5) Compensation and pensions paid by Switzerland to an alien individual, and to a citizen of Switzerland who is also a citizen of the United States, including such items as are from sources without the United States (Article XI);

(6) Private pensions and life annuities paid to a nonresident alien individual who is a resident of Switzerland (Article XI);

(7) Remuneration derived from certain teaching in the United States by a professor or teacher who is a nonresident alien residing in Switzerland (Article XII); and

(8) Dividends and interest paid by a foreign corporation to a nonresident alien who is a resident of Switzerland, or to a Swiss corporation, if such alien or corporation has no permanent establishment in the United States (Article XIV).

(c) Students or apprentices. Remittances received from abroad for the purpose of maintenance or studies by a student or apprentice, a nonresident alien residing in Switzerland, who is temporarily present in the United States under specified circumstances are also exempt from United States tax (Article XIII).

(d) Reduced rates of United States tax. Dividends and interest derived from sources within the United States by a nonresident alien who is a resident of Switzerland, or by a Swiss corporation or other entity, are subject to United States tax at reduced rates, if such alien, corporation, or other entity has no permanent establishment in the United States (Articles VI and VII).

(e) [Reserved]

(f) United States citizens, residents, and corporations. (1) Any citizen of Switzerland who is a resident of the United States is liable to United States tax as though the convention had not come into effect; however, such alien resident of the United States is entitled to the foreign tax credit in accordance with Article XV and is also entitled to the benefits of Article XI (1) and Article XVIII.

(2) A citizen of the United States, even though resident in Switzerland, or a domestic corporation, even though engaged in trade or business in Switzerland through a permanent establishment situated therein, is also liable to United States tax as though the convention had not come into effect but is entitled to the foreign tax credit and, to the extent, applicable, to the benefits of Article XI (1).

(g) Other provisions applicable to Swiss residents and corporations. Except as otherwise expressly provided by the convention, the United States tax liability of a nonresident alien who is a resident of Switzerland, or of a Swiss corporation or other entity, is determined in accordance with the provisions of the Internal Revenue Code of 1954 relating to nonresident alien individuals and foreign corporations.

(a) General. Any term defined in the convention or §§ 509.101 to 509.122 shall have the meaning so assigned to it; any term not so defined shall, unless the context otherwise requires, have the meaning which such term has under the internal revenue laws of the United States.

(b) Specific terms. As used in §§ 509.101 to 509.122—

(1) United States tax. The term “United States tax” means the Federal income taxes, including surtaxes and excess profits taxes, and any other income or profits tax of a substantially similar character imposed by the United States after May 24, 1951.

(2) Swiss tax. The term “Swiss tax” means the federal, cantonal, and communal taxes on income—that is, on total income, earned income, income from property, industrial and commercial profits, etc.—and any other income or profits tax of a substantially similar character imposed by Switzerland after May 24, 1951.

(3) United States. The term “United States” means the United States of America; and, when used in a geographical sense, means the States, the Territories of Alaska and Hawaii, and the District of Columbia.

(4) Switzerland. The term “Switzerland” means the Swiss Confederation.

(5) Permanent establishment—(i) Fixed place of business. The term “permanent establishment” means an office, factory, workshop, warehouse, branch, or other fixed place of business, but does not include the casual and temporary use of merely storage facilities. It implies the active conduct of a business enterprise. The mere ownership, for example, of timberlands or a warehouse in the United States by a Swiss enterprise does not mean that such enterprise, in the absence of any business activity therein, has a permanent establishment in the United States. Moreover, the maintenance within the United States by a Swiss enterprise of a warehouse for convenience of delivery, and not for purposes of display, does not of itself constitute a permanent establishment in the United States, even though offers of purchase have been obtained by an agent therein of the Swiss enterprise and transmitted by him to the Swiss enterprise for acceptance. The fact that a Swiss enterprise maintains in the United States an office or other fixed place of business used exclusively for the purchase for such enterprise of goods or merchandise shall not of itself constitute such fixed place of business a permanent establishment of such enterprise.

(ii) Subsidiary corporation. The fact that a Swiss corporation has a domestic subsidiary corporation, or a foreign subsidiary corporation which is engaged in trade or business in the United States through a permanent establishment situated therein, does not of itself constitute either subsidiary corporation the United States permanent establishment of the Swiss parent corporation.

(iii) Agency. A Swiss enterprise which has an agency in the United States does not thereby have a permanent establishment in the United States, unless the agent has, and habitually exercises, a general authority to negotiate and conclude contracts on behalf of such enterprise or unless he has a stock of merchandise from which he regularly fills orders on its behalf. If the enterprise has an agent in the United States who has power to contract on its behalf, but only at fixed prices and under conditions determined by such principal, it does not thereby necessarily have a permanent establishment in the United States. The mere fact that an agent of a Swiss enterprise—assuming he has no general authority to negotiate and conclude contracts on behalf of his principal—maintains samples, or occasionally fills orders from incidental stocks of goods maintained, in the United States does not of itself mean that such enterprise has a permanent establishment in the United States. The mere fact that salesmen, employees of a Swiss enterprise, promote the sale of their employer's products in the United States or that a Swiss enterprise transacts business in the United States by means of mail order activities does not mean that such enterprise has a permanent establishment in the United States. A Swiss enterprise shall not be deemed to have a permanent establishment in the United States merely because it carries on business dealings in the United States through a commission agent, broker, custodian, or other independent agent, acting in the ordinary course of his business as such.

(6) Enterprise. The term “enterprise” means any commercial or industrial enterprise or undertaking carried on by any person, for example, by an individual partnership, or corporation. It includes such activities as manufacturing, merchandising, mining, processing, banking, and insuring. It does not include the rendition of personal services. Hence, a nonresident alien individual who is resident of Switzerland and who performs personal services is not, merely by reason of such services, engaged in a Swiss enterprise within the meaning of the convention; consequently, his liability to United States tax is not determined under Article III of the convention, if he has not otherwise carried on a Swiss enterprise.

(7) Swiss enterprise. The term “Swiss enterprise” means an enterprise carried on in Switzerland by a nonresident alien individual who is a resident of Switzerland, or by a Swiss corporation or other entity. Thus, an enterprise carried on wholly outside Switzerland by a Swiss corporation is not a Swiss enterprise within the meaning of the convention.

(8) Swiss corporation or other entity. The term “Swiss corporation or other entity” means a corporation or institution or foundation having juridical personality, or a partnership (association “en nom collectif” or “en commandite”), or other association without juridical personality, created or organized under Swiss laws.

(9) United States enterprise. The term “United States enterprise” means an enterprise carried on in the United States by a resident of the United States (including an individual, fiduciary, and partnership) or by a United States corporation or other entity.

(10) United States corporation or other entity. The term “United States corporation or other entity” means a corporation or other entity created or organized under the law of the United States or of any State or Territory of the United States.

(11) Industrial and commercial profits. The term “industrial and commercial profits” means profits arising from industrial, commercial, mercantile, manufacturing, and like activities of an enterprise, including mining, financial and insurance profits. It does not include income in the form of dividends, interests, rents, royalties, or remuneration for personal services. In determining the industrial and commercial profits from sources within the United States of a Swiss enterprise, no profits shall be deemed to arise from the mere purchase of goods or merchandise within the United States by such enterprise. Moreover, in determining such profits of the United States permanent establishment of such enterprise, there shall be allowed as deductions all expenses which are reasonably applicable to the permanent establishment, including executive and general administrative expenses so applicable. See sections 861 through 864, Internal Revenue Code of 1954, and the regulations thereunder.

(12) Commissioner. The term “Commissioner” means the Commissioner of Internal Revenue or his authorized representative.

(13) Director of the Federal Tax Administration. The term “Director of the Federal Tax Administration” means the Director of the Federal Tax Administration (Direktor der eidgenoessischen Steuerverwaltung) of Switzerland.

(a) General. (1) Article III of the convention adopts the principle that an enterprise of one of the contracting States shall not be taxable by the other contracting State upon its industrial and commercial profits unless it is engaged in trade or business in the latter State through a permanent establishment situated therein. Accordingly, a Swiss enterprise is subject to United States tax upon its industrial and commercial profits, to the extent of such profits from sources within the United States, only if it is engaged in trade or business in the United States at some time during the taxable year through a permanent establishment situated therein.

(2) From the standpoint of the United States tax the article has application only to a Swiss enterprise and its industrial and commercial profits from sources within the United States. Thus, a nonresident alien individual who is a citizen of Switzerland, or a Swiss corporation or other entity, carrying on an enterprise which is not Swiss, is subject to tax on such income of such enterprise pursuant to section 871(c) or section 882(a), Internal Revenue Code of 1954, if such alien, corporation, or other entity has engaged in trade or business in the United States at any time during the taxable year, even though it has not had a permanent establishment therein at any time within such year.

(b) No United States permanent establishment. A Swiss enterprise is not subject to United States tax upon its industrial and commercial profits from sources within the United States, nor shall such profits be included in gross income, if it has not at any time during the taxable year engaged in trade or business in the United States through a permanent establishment situated therein. For example, if during the taxable year an enterprise carried on in Switzerland by a nonresident alien individual who is a resident of Switzerland, or by a Swiss corporation, were to sell merchandise, such as watches, dairy products, or liqueurs, in the United States through a commission agent or broker in the United States acting in the ordinary course of his business as such agent or broker, the profits arising from such sale would not be included in gross income and would be exempt from United States tax under Article III of the convention. Similarly, if during the taxable year such enterprise were to secure orders in the United States for such merchandise through its sales agents whose sole function in the United States is sales promotion, the orders being transmitted to Switzerland for acceptance, then the profits arising from such sales would not be included in gross income and would be exempt from United States tax.

(c) United States permanent establishment—(1) General. A Swiss enterprise is subject to United States tax upon its industrial and commercial profits from sources within the United States to the same extent as are nonresident aliens or foreign corporations which are subject to tax pursuant to section 871(c) or section 882(a), Internal Revenue Code of 1954, if such enterprise has at any time during the taxable year engaged in trade or business in the United States through a permanent establishment situated therein. If it is so engaged, it is subject to United States tax upon its entire income from sources within the United States except to the extent otherwise exempt from United States tax.

(2) Allocation of profits. In the determination of the income taxable to such enterprise for purposes of the United States tax, all industrial and commercial profits from sources within the United States shall be deemed to be allocable to the permanent establishment in the United States. Hence, if a Swiss enterprise which has a permanent establishment in the United States at some time during the taxable year were to sell in the United States, through a commission agent therein acting in the ordinary course of his business as such, merchandise which has been produced in Switzerland, the profits arising from such sale would be allocable to the permanent establishment to the extent they are derived from sources within the United States, even though the sale is made independently of the permanent establishment.

(3) Independent basis. The industrial and commercial profits of the permanent establishment in the United States shall be determined as if the establishment were an independent enterprise engaged in the same or similar activities under the same or similar conditions and dealing at arm's length, or on an independent basis, with the enterprise of which it is a permanent establishment.

In effect, Article IV of the convention provides that, if a Swiss enterprise by reason of its control of a United States enterprise imposes on the latter enterprise conditions different from those which would result from normal business relations between independent enterprises, the accounts between the enterprises shall be adjusted in order to ascertain the true taxable income of each enterprise. The purpose is to place the controlled United States enterprise on a tax parity with an uncontrolled United States enterprise by determining, according to the standard of an uncontrolled enterprise, the true taxable income from the property and business of the controlled enterprise. The basic objective of the article is that, if the accounting records do not truly reflect the taxable income from the property and business of the United States enterprise, the Commissioner shall intervene and, by making such distributions, apportionments, or allocations as he may deem necessary of gross income, deductions, credits, or allowances, or of any item or element affecting taxable income, between the United States enterprise and the Swiss enterprise by which it is controlled or directed, shall determine the true taxable income of the United States enterprise. The provisions of section 482 of the Internal Revenue Code of 1954, and the regulations thereunder, shall, insofar as applicable, be followed in the determination of the taxable income of the United States enterprise.

Under Article V of the convention so much of the income from sources within the United States of a Swiss enterprise as consists of earnings derived from the operation of ships or aircraft documented or registered in Switzerland shall not be included in gross income and shall be exempt from United States tax, even though at some time during the taxable year such enterprise has engaged in trade or business in the United States through a permanent establishment situated therein.

(a) General. (1) The rate of United States tax imposed by the Internal Revenue Code of 1954 upon dividends derived from sources within the United States by a nonresident alien individual who is a resident of Switzerland, or by a Swiss corporation or other entity, shall not exceed 15 percent under the provisions of Article VI of the convention, if such alien, corporation, or other entity at no time during the taxable year in which such dividends are derived has a permanent establishment in the United States.

(2) If, for example, a nonresident alien individual who is a resident of Switzerland performs personal services within the United States during the taxable year, but has at no time during such year a permanent establishment within the United States, he is entitled to the reduced rate of tax with respect to dividends derived in that year from United States sources, as provided in Article VI of the convention, even though under the provisions of section 871(c) of the Internal Revenue Code of 1954 he has engaged in trade or business within the United States during such year by reason of his having performed personal services therein.

(b) Dividends paid by related corporation. The rate of United States tax imposed by the Internal Revenue Code of 1954 upon dividends derived from sources within the United States by a Swiss corporation shall not exceed 5 percent under the provisions of Article VI (2) of the convention if:

(1) The Swiss corporation is a shareholder which controls, directly or indirectly, at the time the dividend is paid 95 percent or more of the entire voting power in the corporation paying the dividend;

(2) Not more than 25 percent of the gross income of the paying corporation for the three-year period immediately preceding the taxable year in which the dividend is paid consists of dividends and interest (other than dividends and interest received by such paying corporation from its own subsidiary corporations, if any);

(3) The relationship between the paying corporation and the Swiss corporation has not been arranged or maintained primarily with the intention of securing the reduced rate of 5 percent; and

(4) The Swiss corporation at no time during the taxable year in which such dividends are derived has a permanent establishment in the United States.

The rate of United States tax imposed by the Internal Revenue Code of 1954 upon interest on bonds, securities, notes, debentures, or on any other form of indebtedness, including interest on obligations of the United States, obligations of instrumentalities of the United States, and mortgages and bonds secured by real property, which is derived from sources within the United States by a nonresident alien individual who is a resident of Switzerland, or by a Swiss corporation or other entity, shall not exceed 5 percent under the provisions of Article VII of the convention, if such alien, corporation, or other entity at no time during the taxable year in which such interest is derived has a permanent establishment in the United States.

Royalties and other amounts representing consideration for the right to use copyrights, artistic and scientific works, patents, designs, plans, secret processes and formulae, trademarks, and other like property and rights, including rentals and like payments in respect to motion picture films or for the use of industrial, commercial, or scientific equipment, which are derived from sources within the United States by a nonresident alien individual who is a resident of Switzerland, or by a Swiss corporation or other entity, are exempt from United States tax under the provisions of Article VIII of the convention if such alien, corporation, or other entity at no time during the taxable year in which such items of income are derived has a permanent establishment in the United States.

(a) General. Income of whatever nature derived by a nonresident alien who is a resident of Switzerland, or by a Swiss corporation or other entity, from real property situated in the United States, including gains derived from the sale or exchange of such property, rentals from such property, and royalties in respect of the operation of mines, quarries, or other natural resources situated in the United States, is not exempt from United States tax by the convention. Such items of income are subject to taxation under the provisions of the Internal Revenue Code of 1954 generally applicable to the taxation of nonresident alien individuals and foreign corporations. See Article IX of the convention. Interest derived from mortgages and bonds secured by real property does not constitute income from real property for purposes of this section but is subject to the provisions applicable to interest generally. See § 509.109.

(b) Net basis—(1) General. Notwithstanding the provisions of paragraph (a) of this section, a nonresident alien who is a resident of Switzerland, or a Swiss corporation or other entity, who during the taxable year derives from sources within the United States any income from real property as described in such paragraph may elect for such taxable year to be subject to United States tax on a net basis as though such alien, corporation, or other entity were engaged in trade or business in the United States during such year through a permanent establishment situated therein.

(2) Manner of electing. Such nonresident alien (including an individual, fiduciary, and member of a partnership) shall signify his election to be subject to tax on such a basis by filing Form 104B clearly marked at the top of the first page thereof as follows: “Return of Resident of Switzerland Electing to File on a Net Basis Pursuant to Article IX of Swiss Income Tax Convention”. Such corporation shall signify its election to be subject to tax on such a basis by filing Form 1120 clearly marked at the top of the first page there of as follows: “Return of Swiss Corporation Electing to File on a Net Basis Pursuant to Article IX of Swiss Income Tax Convention”. The election so signified shall be irrevocable for the taxable year for which such election is made. All income from sources within the United States, including gains from the sale or exchange of capital assets or of other property, shall be disclosed on the return so filed. See sections 871 and 882 of the Internal Revenue Code of 1954 and the regulations thereunder.

(a) Exemption from tax. Under Article X of the convention compensation received by a nonresident alien individual who is a resident of Switzerland for labor or personal services, including the practice of the liberal professions and the rendition of services as a director, performed in the United States shall not be included in gross income and shall be exempt from United States tax in either of the following situations:

(1) Swiss employer. Where such individual is temporarily present in the United States for a period or periods not exceeding in the aggregate a total of 183 days during a taxable year beginning on or after January 1, 1951, any compensation received by him (irrespective of when received, if received in taxable years beginning on or after January 1, 1951) for such labor or personal services performed in the United States during such year as an employee of, or under contract with, a nonresident alien (including a nonresident alien individual and fiduciary) who is a resident of Switzerland, or a Swiss corporation or other entity, whether or not such alien, corporation, or other entity is engaged in trade or business within the United States, shall not be included in gross income and shall be exempt from United States tax.

(2) Other employers. Where such individual is temporarily present in the United States for a period or periods not exceeding in the aggregate a total of 183 days during a taxable year beginning on or after January 1, 1951, any compensation received by him (irrespective of when received, if received in taxable years beginning on or after January 1, 1951) for such labor or personal services performed in the United States during such year shall not be included in gross income and shall be exempt from United States tax if such compensation does not exceed $10,000 in the aggregate. Thus, if a nonresident alien individual who is a resident of Switzerland performs personal services in the United States during the taxable year as an employee of a domestic corporation for which he receives compensation of $15,000 in the aggregate, none of such compensation shall be exempt from United States tax even though such individual is present in the United States during such year for a period or periods not exceeding a total of 183 days, since the aggregate compensation received is in excess of $10,000.

(b) Definitions. For purposes of this section, the term “compensation for labor or personal services” shall include, but shall not be limited to, the compensation, profits, emoluments, or other remuneration of public entertainers, such as, stage, motion picture, television, or radio artists, musicians, and athletes. For the allocation or segregation as between sources within, and sources without, the United States in the case of compensation for labor or personal services, see sections 861 through 864, Internal Revenue Code of 1954, and the regulations thereunder.

(c) Exception. The provisions of this section have no application to the income to which Article XI(1) of the convention relates.

(a) General. Under Article XI of the convention any wage, salary, or similar compensation, or any pension, paid by Switzerland or any agency or instrumentality thereof, or by any political subdivisions or other public authorities of Switzerland, to any alien individual (whether or not a resident of the United States) or to any individual who occupies the dual status of a citizen of the United States and a citizen of Switzerland shall not be included in gross income and shall be exempt from United States tax, even though at some time during the taxable year such individual has engaged in trade or business in the United States through a permanent establishment situated therein.

(b) Definition. As used in this section, the term “pensions” means periodic payments made in consideration for services rendered or by way of compensation for injuries received. Under Article XV(2) of the convention the exclusion from gross income, and exemption from United States tax, provided by this section shall not be denied despite the provisions of Article XV. See § 509.118.

(c) Cross reference. For the taxation generally of compensation of alien employees of foreign governments and the consequences of executing and filing the waiver provided for in section 247(b) of the Immigration and Nationality Act, see section 893 of the Internal Revenue Code of 1954 and the regulations thereunder.

(a) General. Private pensions and life annuities derived from sources within the United States and paid to a nonresident alien individual who is a resident of Switzerland shall not be included in gross income and shall be exempt from United States tax, in accordance with Article XI of the convention, even though at some time during the taxable year such individual has engaged in trade or business in the United States through a permanent establishment situated therein.

(b) Definitions. As used in this section, the term “pensions” means periodic payments made in consideration for services rendered or by way of compensation for injuries received; and the term “life annuities” means a stated sum payable periodically at stated times during life, or during a specified number of years, under an obligation to make the payments in return for adequate and full consideration in money or money's worth.

(a) General. Pursuant to Article XII of the convention, a professor or teacher, a nonresident alien who is a resident of Switzerland, who temporarily visits the United States for the purpose of teaching for a period not exceeding two years at any university, college, school, or other educational institution situated within the United States shall, for a period not exceeding two years from the date of his initial arrival in the United States, be exempt from United States tax with respect to his remuneration earned in taxable years beginning on or after January 1, 1951, for such teaching during such period not in excess of two years.

(b) More than two years. The exemption granted by Article XII is applicable to remuneration earned during such part of the individual's visit as does not exceed two years from the date of arrival even though the total period of his presence in the United States may extend beyond two years, provided that during such entire period he may be considered to be temporarily visiting the United States.

(c) Residence. Such exemption shall not apply to the remuneration of an alien who is a resident of the United States or who is not a resident of Switzerland.

(d) Nonresidence presumed. An individual who otherwise qualifies for the exemption from United States tax granted by Article XII shall, for a period of not more than two years immediately succeeding the date of his arrival within the United States for the purpose of such teaching, be deemed to have the tax status of a nonresident alien in the absence of proof of his intention to remain indefinitely in the United States. See section 871 of the Internal Revenue Code of 1954 and the regulations thereunder.

(a) General. Under Article XIII of the convention, a student or apprentice, a nonresident alien who is a resident of Switzerland, who temporarily visits the United States exclusively for the purposes of study or for acquiring business or technical experience shall not include in gross income, and shall be exempt from United States tax with respect to, amounts derived by him in taxable years beginning on or after January 1, 1951, and received during such years from without the United States as remittances for the purposes of his maintenance or studies.

(b) Residence. The exemption shall not apply to remittances received by an alien who is a resident of the United States or who is not a resident of Switzerland.

(a) [Reserved]

(b) Exemption from United States tax. Notwithstanding the provisions of paragraph (a) of this section, Article XIV(1) of the convention provides that dividends and interest paid by any foreign corporation and derived by a nonresident alien who is a resident of Switzerland, or by a Swiss corporation, shall not be included in gross income and shall be exempt from United States tax if such alien or corporation at no time during the taxable year in which such items of income are derived has a permanent establishment in the United States. The exemption so provided shall apply even though the corporation paying the dividends or interest is a resident foreign corporation at the time of payment and without regard to the percentage of its gross income from sources within the United States.

(a) General—(1) Taxable as though no convention. Notwithstanding any other provision of the convention the United States, in determining the United States tax of a citizen or resident of the United States, or of a domestic corporation, may, under Article XV(1)(a) of the convention, include in the basis upon which such tax is imposed all items of income taxable under the revenue laws of the United States, as though the convention had not come into effect. For example, despite the exemption from United States tax granted by Article VIII of the convention with respect to a copyright royalty derived from sources within the United States by a resident of Switzerland, such royalty shall be included in gross income and is subject to United States tax when so derived by a resident of Switzerland who is a citizen of the United States, even though such resident has no permanent establishment in the United States.

(2) Exception. Notwithstanding the provisions of subparagraph (1) of this paragraph, the exclusion from gross income, and exemption from United States tax, granted by Article XI(1) of the convention with respect to wages, salaries, and similar compensation, and pensions, paid by Switzerland or any agency or instrumentality thereof, or by any political subdivisions or other public authorities of Switzerland, shall not be denied. See Article XV(2) of the convention.

(b) Application of credit—(1) General. For the purpose of mitigating double taxation, Article XV(1)(a) of the convention provides that a citizen or resident of the United States, or a domestic corporation, deriving income from sources within Switzerland shall be allowed a credit against the United States tax for the amount of Swiss tax paid or accrued during the taxable year. This credit shall be made in accordance with the provisions of section 131 of the Internal Revenue Code of 1939 as in effect on September 27, 1951, but subject to the provisions of Article XVIII(2) of the convention.

(2) Similar credit requirement. (i) Article XV(1)(a) further provides that, by virtue of the provisions of Article XV(1)(b) of the convention, relating to the exclusion from basis for computing the Swiss tax, Switzerland satisfies the similar credit requirement set forth in section 901(b)(3), Internal Revenue Code of 1954, relating to alien residents of the United States, etc.

(ii) This provision of Article XV(1)(a) shall be taken to mean that, solely by reason of the exclusion granted by it under Article XV(1)(b) and without reference to concessions otherwise made by such country, Switzerland satisfies the similar credit requirement only with respect to taxes paid to Switzerland, and not with respect to taxes paid to another foreign country. Nothing in this subdivision shall be construed, however, to prevent Switzerland from otherwise satisfying the similar credit requirement, in accordance with section 901 of the Internal Revenue Code of 1954 and the regulations thereunder, with respect to taxes paid to another foreign country. Thus, if pursuant to a convention between Switzerland and another foreign country, Switzerland were to exempt from its income taxes the income received from sources within such other foreign country by a United States citizen residing in Switzerland, then Switzerland would, in accordance with such regulations under section 901, satisfy the similar credit requirement of section 901(b)(3) with respect to income taxes paid to such other country by a Swiss citizen residing in the United States.

(a) General. Under Article XVII of the convention, where the taxpayer shows proof that the action of the tax authorities of the United States or Switzerland has resulted, or will result, in double taxation contrary to the provisions of the convention, he is entitled to present the facts to the country of which he is a citizen; or, if he is not a citizen of either country, to the country of which he is a resident; or, if the taxpayer is a corporation or other entity, to the country in which it is created or organized. The article provides that, should the taxpayer's claim be deemed worthy of consideration, the competent authority of the country to which the facts are presented shall undertake to come to an agreement with the competent authority of the other country with a view to equitable avoidance of the double taxation in question.

(b) Manner of filing claim. Such a claim on behalf of a United States citizen, corporation, or other entity, or on behalf of a resident of the United States who is not a Swiss citizen, shall be filed with the Commissioner. The claim shall be set up in the form of a letter addressed to “The Commissioner of Internal Revenue, Washington, D.C.” and shall show fully all facts and laws on the basis of which the claimant alleges that such double taxation has resulted or will result.
