ARTICLE IX

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

Related Persons

Paragraph 1 authorizes Canada and the United States, as the case may be, to adjust the amount of income, loss, or tax payable by a person with respect to arrangements between that person and a related person in the other Contracting State. Such adjustment may be made when arrangements between related persons differ from those that would obtain between unrelated persons. The term "person" encompasses a company resident in a third State with, for example, a permanent establishment in a Contracting State.

Paragraph 2 provides that, for the purposes of Article IX, a person is deemed to be related to another person if either participates directly or indirectly in the management or control of the other or if any third person or persons participate directly or indirectly in the management or control of both. Thus, if a resident of any State controls directly or indirectly a company resident in Canada and a company resident in the United States, such companies are considered to be related persons for purposes of Article IX. Article IX and the definition of“related person” in paragraph 2 may encompass situations that would not be covered by provisions in the domestic laws of the Contracting States. Nor is the paragraph 2 definition controlling for the definition of "related person" or similar terms appearing in other Articles of the Convention. Those terms are defined as provided in paragraph 2 of Article III (General Definitions).

Paragraph 3 provides that where, pursuant to paragraph 1, an adjustment is made or to be made by a Contracting State, the other Contracting State shall make a corresponding adjustment to the income, loss, or tax of the related person in that other State, provided that the other State agrees with the adjustment and, within six years from the end of the taxable year of the person in the first State to which the adjustment relates, the competent authority of the other State has been notified in writing of the adjustment. The reference to an adjustment which "is made or to be made" does not require a Contracting State to formally propose an adjustment before paragraph 3 becomes pertinent. The notification required by paragraph 3 may be made by any of the related persons involved or by the competent authority of the State which makes or is to make the initial adjustment. The notification must give details regarding the adjustment sufficient to apprize the competent authority receiving the notification of the nature of the adjustment. If the requirements of paragraph 3 are complied with, the corresponding adjustment will be made by the other

Contracting State notwithstanding any time or procedural limitations in the domestic law of that State.

Paragraph 4 provides that in a case where the other Contracting State has not been notified as provided in paragraph 3 and if the person whose income, loss, or tax is being adjusted has not received notification of the adjustment within five and one-half years from the end of its taxable year to which the adjustment relates, such adjustment shall not be made to the extent that the adjustment would give rise to double taxation between the United States and Canada. Again, the notification referred to in this paragraph need not be a formal adjustment, but it must be in writing and must contain sufficient details to permit the taxpayer to give the notification referred to in paragraph 3.

If, for example, the Internal Revenue Service proposes to make an adjustment to the income of a U.S. company pursuant to Code section 482, and the adjustment involves an allocation of income from a related Canadian company, the competent authority of Canada must receive written notification of the proposed IRS adjustment within six years from the end of the taxable year of the U.S. company to which the adjustment relates. If such notification is not received in a timely fashion and if the U.S. company does not receive written notification of the adjustment from the IRS within 5-1/2 years from the end of its relevant taxable year, the IRS will unilaterally recede on the proposed section 482 adjustment to the extent that this adjustment would otherwise give rise to double taxation between the United States and Canada. The Internal Revenue Service will determine whether and to what extent the adjustment would give rise to double taxation with respect to income arising in Canada by examining the relevant facts and circumstances such as the amount of foreign tax credits attributable to Canadian taxes paid by the U.S. company, including any carry-overs and credits for deemed paid taxes.

Paragraph 5 provides that neither a corresponding adjustment described in paragraph 3 nor the canceling of an adjustment described in paragraph 4 will be made in any case of fraud, willful default, neglect, or gross negligence on the part of the taxpayer or any related person.

Paragraphs 3 and 4 of Article IX are exceptions to the "saving clause" contained in paragraph 2 of Article XXIX (Miscellaneous Rules), as provided in paragraph 3(a) of Article XXIX. Paragraphs 3 and 4 of Article IX apply to adjustments made or to be made with respect to taxable years for which the Convention has effect as provided in paragraphs 2 and 5 of Article XXX (Entry Into Force).
