ARTICLE XXI
U.S. Income Tax Treaty — Canada Technical Explanation - 1980 · 2026-10-03 edition · updated 2026-10-04 · United States
Exempt Organizations
Paragraph 1 provides that a religious, scientific, literary, educational, or charitable organization resident in a Contracting State shall be exempt from tax on income arising in the other Contracting State but only to the extent that such income is exempt from taxation in the Contracting State in which the organization is resident. Since this paragraph, and the remainder of Article XXI, deal with entities that are not normally taxable, the test of "resident in” is intended to be similar - but cannot be identical - to the one outlined in paragraph 1 of Article IV (Residence). Paragraph 3 provides that paragraph 1 does not exempt from tax, income of a trust, company, or other organization from carrying on a trade or business, or income from a "related person" other than a person referred to in paragraph 1 or 2.
Paragraph 2 provides that a trust, company, or other organization that is resident in a Contracting State constituted and operated exclusively to administer or provide employee benefits or benefits for the self-employed under one or more funds or plans established to provide pension or retirement benefits or other employee benefits is exempt from taxation on dividend and interest income arising in the other Contracting State in a taxable year, if the income of such, organization is generally exempt from taxation for that year in the Contracting State in which it is resident. In addition, a trust, company, or other organization resident in a Contracting State and not taxed in a taxable year in that State shall be exempt from taxation in the other State in that year on dividend and interest income arising in that other State if it is constituted and operated exclusively to earn, income for the benefit of an organization described in the preceding sentence. Pursuant to paragraph 3 the exemption at source provided by paragraph 2 does not apply to dividends or interest from carrying on trade or business or from a "related person," other than a person referred
to in paragraph 1 or 2. The term "related person" is not necessarily defined by paragraph 2 of Article IX (Related Persons).
Paragraph 4 provides an exemption from U.S. excise taxes on private foundations in the case of a religious, scientific, literary, educational, or charitable organization which is resident in Canada but only if such organization has received substantially all of its support from persons other than citizens or residents of the United States.
Paragraph 5 provides that contributions by a citizen or resident of the United States to an organization which is resident in Canada and is generally exempt from Canadian tax are treated as charitable contributions, but only if the organization could qualify in the United States to receive deductible contributions if it were resident in (i.e., organized in) the United States. Paragraph 5 generally limits the amount of contributions made deductible by the Convention to the income of the U.S. citizen or resident arising in Canada, as determined under the Convention. In the case of contributions to a college or university at which the U.S. citizen or resident or a member of his family is or was enrolled, the special limitation to income arising in Canada is not required. The percentage limitations of Code section 170 in respect of the deductibility of charitable contributions apply after the limitations established by the Convention. Any amounts treated as charitable contributions by paragraph 5 which are in excess of amounts deductible in a taxable year pursuant to paragraph 5 may be carried over and deducted in subsequent taxable years, subject to the limitations of paragraph 5.
Paragraph 6 provides rules for purposes of Canadian taxation with respect to the deductibility of gifts to a U.S. resident organization by a resident of Canada. The rules of paragraph 6 parallel the rules of paragraph 5. The current limitations in Canadian law provide that deductions for gifts to charitable organizations may not exceed 20 percent of income. Excess deductions may be carried forward for one year.
The term “family” used in paragraphs 5 and 6 is defined in paragraph 2 of the Exchange of Notes accompanying the Convention to mean an individual's brothers and sisters (whether by whole or half-blood, or by adoption), spouse, ancestors, lineal descendants, and adopted descendants. Paragraph 2 of the Exchange of Notes also provides that the competent authorities of Canada and the United States will review procedures and requirements for organizations to establish their exempt status under paragraph 1 of Article XXI or as an eligible recipient of charitable contributions or gifts under paragraphs 5 and 6 of Article XXI. It is contemplated that such review will lead to the avoidance of duplicative administrative efforts in determining such status and eligibility.
The provisions of paragraph 5 and 6 generally parallel the rules of Article XIII D of the 1942 Convention. However, paragraphs 5 and 6 permit greater deductions for certain contributions to colleges and universities than do the provisions of the 1942 Convention.
