Income Tax Act

Clause 17


Section 241 prohibits the use or communication of taxpayer information except as authorized. Subsection 241(4) permits a government official to communicate taxpayer information for limited purposes.

New paragraph 241(4)(u) authorizes the communication of certain taxpayer information to an official of the Department of Industry, solely for the purpose of the verifying and validating data required to be filed by certain private corporations under section 21.21 of the Canada Business Corporations Act in relation to the corporate beneficial ownership registry. Specifically, the information that may be provided under paragraph (u) is information on shareholdings and corporate ownership structures of private corporations reported to the Canada Revenue Agency through schedules 9 and 50 of the T2 Corporation Income Tax Return.

This amendment comes into force on a day to be fixed by order of the Governor in Council.
