Canada–United States Tax Convention Act, 1984 — C-10.7 “ARTICLE XXVI A

For the purposes of this Article, a revenue claim is finally determined when the applicant State has the right under its internal law to collect the revenue claim and all administrative and judicial rights of the taxpayer to restrain collection in the applicant State have lapsed or been exhausted. 3 A revenue claim of the applicant State that has been finally determined may be accepted for collection by the competent authority of the requested State and, subject to the provisions of paragraph 7, if accepted shall be collected by the requested State as though such revenue claim were the requested State’s own revenue claim finally determined in accordance with the laws applicable to the collection of the requested State’s own taxes. 4 Where an application for collection of a revenue claim in respect of a taxpayer is accepted (a) By the United States, the revenue claim shall be treated by the United States as an assessment under United States laws against the taxpayer as of the time the application is received; and (b) By Canada, the revenue claim shall be treated by Canada as an amount payable under the Income Tax Act , the collection of which is not subject to any restriction. 5 Nothing in this Article shall be construed as creating or providing any rights of administrative or judicial review of the applicant State’s finally determined revenue claim by the requested State, based on any such rights that may be available under the laws of either Contracting State.
