What's New

Under Revenue Procedure 2014-55, 2014-44 I.R.B. 753, available at, there are new procedures for electing to defer U.S. tax on undistributed income from certain Canadian retirement plans (including RRSPs and RRIFs). Form 8891 is no longer required to make the election or to report distributions or earnings on undistributed income. Revenue Procedure 2014-55 also provides guidance concerning information reporting with respect to interests in certain Canadian retirement plans. For more information, see Tax-deferred plans under Pensions, Annuities, Social Security, and Alimony, later.


This publication provides information on the income tax treaty between the United States and Canada. It discusses a number of treaty provisions that most often apply to U.S. citizens or residents who may be liable for Canadian tax.

Treaty provisions are generally reciprocal (the same rules apply to both treaty countries). Therefore, Canadian residents who receive income from the United States may also refer to this publication to see if a treaty provision affects their U.S. tax liability.

This publication does not deal with Canadian income tax laws; nor does it provide Canada's interpretation of treaty articles, definitions, or specific terms not defined in the treaty itself. For questions regarding Canadian taxation, contact the Canada Revenue Agency at

The United States–Canada income tax treaty was signed on September 26, 1980. It has been amended by five protocols, the most recent of which generally became effective January 1, 2009. In this publication, the term “article” refers to the particular article of the treaty, as amended.
