Once completed, Form NR73 or NR74, as applicable, should be mailed to the address given above or faxed to (613) 941-2505. In most cases, the CCRA will be able to provide an opinion regarding a taxpayer's residence status from the information recorded on the completed form. This opinion is based entirely on the facts provided by the taxpayer to the CCRA in Form NR73 or NR74, as applicable, therefore, it is critical that the taxpayer provide all of the details concerning his or her residential ties with Canada and abroad. This opinion is not binding on the CCRA and may be subject to a more detailed review at a later date and supporting documentation may be required at that time.
¶ 25. An individual who is a resident of Canada for purposes of the Act is a resident of Canada for purposes of paragraph 1 of the Residence Article of any modern tax treaty between Canada and another country; such an individual may also be a resident of the other country for purposes of the same paragraph in the same treaty. In this situation, the Residence Article in the tax treaty will provide "tie breaker rules" to determine in which country the individual will be resident for purposes of the other provisions of the treaty. If, at any time, such "tie breaker rules" apply and it is determined that an individual is a resident of another country for purposes of a tax treaty between Canada and that country, then subsection 250(5) of the Act will deem the individual to be a non-resident of Canada for purposes of the Act (see ¶ 24). "Permanent Home" and "Center of Vital Interests" Tests
¶ 26. "Tie-breaker rules" are found in paragraph 2 of Article IV of most modern income tax treaties. Usually, these rules rely first on a "permanent home" test to resolve the residence issue. Generally, the "permanent home" test provides that an individual is resident for purposes of the treaty in the country in which the individual has a permanent home available to him or her. A "permanent home" (as that term is used in income tax treaties) may be any kind of dwelling place that the individual retains for his or her permanent (as opposed to occasional) use, whether that dwelling place is rented or purchased or otherwise occupied on a permanent basis. Therefore, an individual may have two permanent homes while living outside Canada (for example, a dwelling place rented by the individual abroad and a property owned by the individual in Canada that continues to be available for his or her use, such as a home that is not leased to a third party on arm's length terms and conditions as described in ¶ 6) and the "permanent home" test will not result in a residency determination. Where this is the case, the "tie-breaker rules" of most treaties then refer to the "center of vital interests" test. The "center of vital interests" test requires a close examination of the individual's personal and economic ties with each country in question, in order to determine with which country those ties are closer. The personal and economic ties to be examined are similar to those used in determining factual residence for purposes of Canadian income tax (see especially ¶s 4 to 9). There are other tests that will apply if the "center of vital interests" test is inconclusive.
