ARTICLE XXVI

U.S. Income Tax Treaty — Canada Technical Explanation - 1980 · 2026-10-03 edition · updated 2026-10-04 · United States

Mutual Agreement Procedure

Paragraph 1 provides that where a person considers that the actions of one or both of the Contracting States will result in taxation not in accordance with the Convention, he may present his case in writing to the competent authority of the Contracting State of which he is a resident or, if he is a resident of neither Contracting State, of which he is a national. Thus, a resident of Canada must present to the Minister of National Revenue (or his authorized representative) any claim that such resident is being subjected to taxation contrary to the Convention. A person who requests assistance from the competent authority may also avail himself of any remedies available under domestic laws.

Paragraph 2 provides that the competent authority of the Contracting State to which the case is presented shall endeavor to resolve the case by mutual agreement with the competent authority of the other Contracting State, unless he believes that the objection is not justified or he is able to arrive at a satisfactory unilateral solution. Any agreement reached between the competent authorities of Canada and the United States shall be implemented notwithstanding any time or other procedural limitations in the domestic laws of the Contracting States, except where the special mutual agreement provisions of Article IX (Related Persons) apply, provided that the competent authority of the Contracting State asked to waive its domestic time or procedural limitations has received written notification that such a case exists within six years from the end of the taxable year in the first-mentioned State to which the case relates. The notification may be given by the competent authority of the first-mentioned State, the taxpayer who has requested the competent authority to take action, or a person related to the taxpayer. Unlike Article IX, Article XXVI does not require the competent authority of a Contracting State to grant unilateral relief to avoid double taxation in a case where timely notification is not given to the competent authority of the other Contracting State. Such unilateral relief may, however, be granted by the competent authority in its discretion pursuant to the provisions of Article XXVI and in order to achieve the purposes of the Convention. In a case where the provisions of Article IX apply, the provisions of paragraphs 3, 4, and 5 of that Article are controlling with respect to adjustments and corresponding adjustments of income, loss, or tax and the effect of the Convention upon time or procedural limitations of domestic law. Thus, if the provisions of paragraph 2 of Article XXVI do not independently authorize such relief.

Paragraph 3 provides that the competent authorities of the Contacting States shall endeavor to resolve by mutual agreement any difficulties or doubts arising as to the interpretation or application of the Convention. In particular, the competent authorities may agree to the same attribution of profits to a resident of a Contracting State and its permanent establishment in the other Contracting State; the same allocation of income, deductions, credits, or allowances between persons; the same determination of the source of income; the same characterization of particular items of income; a common meaning of any term used in the Convention; rules, guidelines, or procedures for the elimination of double taxation with respect to income distributed

by an estate or trust, or with respect to a partnership; or to increase any dollar amounts referred to in the Convention to reflect monetary or economic developments. The competent authorities may also consult and reach agreements on rules, guidelines, or procedures for the elimination of double taxation in cases not provided for in the Convention.

The list of subjects of potential mutual agreement in paragraph 3 is not exhaustive; it merely illustrates the principles set forth in the paragraph. As in the case of other U.S. tax conventions, agreement can be arrived at in the context of determining the tax liability of a specific person or in establishing rules, guidelines, and procedures that will apply generally under the Convention to resolve issues for classes of taxpayers. It is contemplated that paragraph 3 could be utilized by the competent authorities, for example, to resolve conflicts between the domestic laws of Canada and the United States with respect to the allocation and apportionment of deductions.

Paragraph 4 provides that each Contracting State will endeavor to collect on behalf of the other State such amounts as may be necessary to ensure that relief granted by the Convention from taxation imposed by the other State does not enure to the benefit of persons not entitled to such relief. Paragraph 4 does not oblige either Contracting State to carry out administrative measures of a different nature from those that would be used by Canada or the United States in the collection of its own tax or which would be contrary to its public policy.

Paragraph 5 confirms that the competent authorities of Canada and the United States may communicate with each other directly for the purpose of reaching agreement in the sense of paragraphs 1 through 4.
