The United States–Canada income tax treaty was signed on September 26, 1980. It has been amended by protocols signed June 14, 1983, March 28, 1984, March 17, 1995, and July 29, 1997.

The United States has entered into a bilateral income tax treaty with Canada primarily to reduce or eliminate double taxation of income of residents of the treaty countries. With respect to the US taxation of foreign persons of a treaty country, treaties operate to reduce or eliminate double taxation principally as follows:

  • Exemption from or reduced rates of US withholding tax generally are provided for gross dividends, interest, and royalties received as investment income from US sources; and
  • The business income of a foreign corporation or other foreign enterprise is not subject to taxation by the United States unless attributable to a permanent establishment of the foreign enterprise in the United States.

A permanent establishment generally is an office or other fixed place of business. However, a permanent establishment generally does not include a fixed place of business in the United States used only for certain activities, including:

  • The use of facilities for the purpose of storage, display, or the delivery of goods
  • The maintenance of a stock of goods or merchandise for the purpose of storage, display, or delivery
  • The purchase of goods or merchandise or the collection of information
  • Advertising, the supply of information, scientific research, or similar auxiliary activities.

A foreign enterprise from a treaty country generally is not deemed to have a permanent establishment in the United States merely because that enterprise carries on business in the United States through a broker, general commission agent, or any other independent agent.

Treaties also provide special rules for the income taxation of shipping and transport activities, real property, independent personal services, dependent (e.g., employee) personal services, pensions and annuities, foreign government employees, and foreign teachers, students and business apprentices.

Treaties generally contain non-discrimination articles, which provide that nationals (generally corporations and citizens) of one country will not be subject to taxation by the second country that is different or more burdensome than the taxation to which the nationals of the second country are subjected in the same circumstances.

Another purpose of treaties is to prevent tax evasion. To this end, treaties establish procedures for the exchange of information between the treaty partners.

Generally, treaty provisions will override federal domestic law. Exceptions exist regarding the US taxation of gains on the disposition of US real property interests and regarding the imposition of the branch profits tax in treaty shopping situations.

Disclosure of Treaty-Based Return Positions

Any taxpayer taking a tax return position where a US treaty overrides or modifies an Internal Revenue law must disclose that position in a tax return. Such a return position will need to be disclosed if the tax liability reported on the taxpayer's return differs from the tax liability that would have been reported if the treaty did not exist. Also, taxpayers that otherwise would not be required to file a US return must now file a return to disclose return positions based on treaty provisions. For example, any foreign corporation claiming exemption from US tax on its US business income as a result of having no permanent establishment in the United States will now have to disclose that position in a tax return.

Failure to comply with these reporting requirements may result in separate penalties for each failure to disclose a position. The penalty is $10,000 for each failure for a corporation. However, the penalties may be waived if the taxpayer makes an affirmative showing of lack of wilful neglect.
