Switzerland: double taxation agreement, Article 21: Other income
(1) Items of income of a resident of a Contracting State, wherever arising, not dealt with in the foregoing Articles of this Convention, other than income paid out of trusts, shall be taxable only in that State.
(2) The provisions of paragraph (1) shall not apply to income other than income from immovable property as defined in paragraph (2) of Article 6, if the recipient of such income, being a resident of a Contracting State, carries on business in the other Contracting State through a permanent establishment situated therein, or performs in that other State independent personal services from a fixed base situated therein, and the right or property in respect of which the income is paid is effectively connected with such permanent establishment or fixed base. In that case, the provisions of Article 7 or Article 14, as the case may be, shall apply.
(3) Where, by reason of a special relationship between the resident referred to in paragraph 1 and some other person, or between both of them and some third person, the amount of the income referred to in that paragraph exceeds the amount (if any) which would have been agreed upon between them in the absence of such a relationship, the provisions of this Article shall apply only to the last-mentioned amount. In such a case, the excess part of the income shall remain taxable according to the laws of each Contracting State, due regard being had to the other applicable provisions of this Convention.
(4) The provisions of this Article shall not apply in respect of any items of income referred to in paragraph 1 if paid under, or as part of, a conduit arrangement.
