The continued impact of enhanced mandatory disclosure rules in Canada

It has been over a year since Canada’s enhanced mandatory disclosure rules (MDR) were enacted via Bill C-47 on June 22, 2023. Taxpayers and their advisors are taking steps to address the continued impact of these broadly legislated disclosure requirements.

The MDR regime consists of three types of transactions: reportable transactions, notifiable transactions, and uncertain tax treatment.

The purpose of the MDR is to improve the collection of relevant information to help the Canada Revenue Agency (CRA) effectively and efficiently respond to tax risks through informed risk assessments, audits, and changes to legislation.

The enhanced MDR regime is extremely broad. This regime expanded the previously existing “reportable transactions” requirements and introduced new reporting requirements for “notifiable transactions” and “reportable uncertain tax treatments”.

In general terms, a transaction is considered a reportable transaction if it meets one of the three hallmarks: contingent fee arrangement, confidential protection, or contractual protection, and if one of the main purposes of the transaction is to obtain a tax benefit.

Notifiable transactions include both transactions that the CRA has found to be abusive, and transactions identified as transactions of interest (that is, where more information is required to determine if a transaction is abusive).

The CRA has the authority to designate, with the concurrence of the Minister of Finance, transactions or series of transactions for purposes of the notifiable transaction rules.

To date, the CRA has designated five types of transactions and series of transactions as notifiable, effective November 1, 2023:

• Straddle loss creation transactions using a partnership
• Avoidance of deemed disposal of trust property
• Manipulation of bankrupt status to reduce a forgiven amount in respect of a commercial obligation
• Reliance on purpose tests in section 256.1 to avoid a deemed acquisition of control
• Back-to-back arrangements.

A transaction becomes a notifiable transaction if it is the same or “substantially similar” to the above designated transactions.

An uncertain tax treatment is a tax treatment that an entity used or plans to use in its Canadian income tax filings for which there is uncertainty over whether the CRA will accept the tax treatment as being in accordance with tax law.

In general terms, this filing requirement is imposed on reporting corporations that report an uncertain tax treatment in their audited financial statements either by way of a tax provision or note disclosure in reference to the particular tax issue. These statements are prepared either in accordance with International Financial Reporting Standards (IFRS) or the country-specific Generally Accepted Accounting Principles (GAAP) relevant for public companies listed outside Canada (e.g., U.S. GAAP).
