Changes to Mandatory Disclosure: know your obligations under the proposed new rules

Farris' Christopher Ellett and Trevor Shum detail upcoming changes to the Income Tax Act

As part of the 2021 federal budget, the government proposed expanding the existing “reportable transactions” rules in section 237.3 of Canada’s Income Tax Act (the “ITA”), introducing a new category of “notifiable transactions”, extending the normal reassessment period, and expanding and increasing penalties for non-compliance with reporting rules, among other proposals (collectively, the “Mandatory Disclosure Proposals”).

The draft legislation to implement the Mandatory Disclosure Proposals was released on February 4, 2022. On August 9, 2022, the Department of Finance released amended draft legislation (the “Amended Proposals”). The Amended Proposals are open for comment until September 30, 2022. Under the Amended Proposals, the application date of the new rules will be the beginning of 2023.

With the Mandatory Disclosure Proposals, the government also released rules for reporting of uncertain tax positions set out in the 2021 federal budget. Those rules are not covered in this article.

Proposed Changes to Reportable Transaction Obligations

The existing reportable transaction rules apply when the transaction constitutes an avoidance transaction and two of the three following hallmarks are present, which in general terms are:

  1. a promoter or advisor is entitled to receive contingent fees on the transaction;
  2. a promoter or advisor obtains confidential protection with respect to the transaction; and
  3. the taxpayer or certain other persons (including a promotor or advisor) receives contractual protection if the transaction does not achieve the intended tax benefit.

Under the Mandatory Disclosure Proposals and Amended Proposals, a transaction would be reportable if it can reasonably be concluded that one of the main purposes of entering into the transaction is to obtain a tax benefit (a lower threshold than the current “avoidance transaction” requirement) and only one generic hallmark must be present. The Amended Proposals clarify the circumstances in which the confidentiality protection in the second hallmark can trip the reportable transaction threshold to situations where the confidentiality protection covers the tax treatment of the transaction. The Amended Proposals also attempt to clarify that the contractual protection that is contemplated in the third hallmark should not capture normal commercial transactions.

New Notifiable Transaction Obligations

The Mandatory Disclosure Proposals introduce reporting for transactions that the Canada Revenue Agency (“CRA”) has found to be abusive, and transactions identified as transactions of interest (i.e., potentially abusive in CRA’s view). A notifiable transaction is defined as a transaction that is the same or substantially similar to a transaction designated by the Minister of Finance (the “Minister”) The Minister has initially designated six types of transactions, which in general terms are:

  1. manipulating Canadian-controlled private corporation status to avoid anti-deferral rules that apply to investment income;
  2. creating loss straddle transactions using a partnership;
  3. avoiding the 21-year deemed disposition of trust property;
  4. manipulating bankruptcy status to reduce a forgiven amount relating to a commercial obligation;
  5. relying on certain purpose tests to avoid a deemed acquisition of control; and
  6. using back-to-back arrangements to circumvent the thin capitalization rules and Part XIII withholding tax.

The Amended Proposals left these rules largely the same but provide that the reporting obligations shall generally not apply to banks, insurance companies and credit unions who do not know that the transaction is a notifiable transaction.

Reporting Obligations and Returns

The Mandatory Disclosure Proposals and Amended Proposals require each taxpayer entering into a notifiable or a reporting transaction or any other person who enters into such a transaction for the benefit of the taxpayer to fulfil certain reporting obligations.

For notifiable transactions, these reporting obligations also apply to all advisors or promoters in respect of the transaction. For reportable transactions, these reporting obligations apply to all advisors or promoters who receive a contingent fee based on tax benefits obtained under the transaction or the number of taxpayers who participate in the transaction, or an advisor or promoter who receives a fee in connection with contractual protection provided in the transaction. However, under the Amended Proposals for both notifiable and reportable transactions, persons who only provide clerical or secretarial services with respect to the planning will not have a reporting obligation.

Unlike under the existing rules for reportable transactions, a single report on behalf of all persons obliged to report will no longer be acceptable. Although in some instances, a return filed in respect of a notifiable transaction by an employer or another partner in the partnership will deem all other employees and partners to have also reported.

Under one’s notifiable and reportable transactions obligations, reporting consists of filing an information return setting out detailed information about the expected tax benefits, ITA provisions relied on, and other information including who else may be required to notify CRA under these rules.

Taxpayers, advisors, and promoters who have an obligation to file an information return, must do so within 45 days from the earlier of the date the taxpayer becomes contractually obligated to enter into the transaction or the day the taxpayer enters into the transaction. An exception will apply for reporting information subject to solicitor-client privilege.

Harsher Penalties

The Mandatory Disclosure Proposals contain significant penalties for taxpayers, advisors, and promoters who fail to report or file. For advisors and promoters the penalties are up to the fees charged for the matter plus $110,000.

In addition, the normal reassessment period will not commence until the reporting obligations in respect of a transaction are met. Therefore, if any reporting obligations in respect of a transaction are not met, then the normal reassessment period could be extended indefinitely.

Impetus for the Mandatory Disclosure Proposals

The government identified lack of timely, comprehensive and relevant information on aggressive tax planning strategies to be one of the main challenges faced by tax authorities worldwide and stated that early access to this information allows tax authorities to respond quickly to tax risks through informed risk assessments, audits and changes to legislation. It believes the current rules are not sufficiently robust.

Impact on Tax and Non-tax Advisors

The Mandatory Disclosure Proposals contain lower reporting and filing thresholds than the existing rules, and therefore will oblige advisors to report in instances where aggressive tax planning is not intended and may even apply to routine transactions. While the Amended Proposals attempt to clarify some aspects of the original proposals, the results are mixed. Tax advisors must be aware of the Mandatory Disclosure Proposals and Amended Proposals and review their transactions to ensure their own reporting obligations are met, but also to ensure that all the relevant parties have fulfilled their reporting obligations as well.

Certain non-tax advisors may be required to report or disclose even where their work is not directly tied to providing a tax benefit but is connected to a notifiable transaction or a reportable transaction. These advisors may find it difficult to determine their reporting obligations without knowledge of other transactions involved and/or assistance from tax advisors. Aside from exposure to penalties, non-reporting could substantially prejudice their clients’ interests by delaying the start of limitation periods on tax return assessments. At the same time, unnecessary reporting by advisors may also expose their clients to additional scrutiny by the CRA.

Concerns Raised

Several concerns have been raised by tax practitioners and other stakeholders, best detailed by the Joint Committee on Taxation of the Canadian Bar Association and CPA Canada (the “Joint Committee”) in their April 5, 2022, submission. Their submission identifies several concerns regarding the draft legislation as it pertains to the reportable transactions rules and the requirement to report notifiable transactions. A theme throughout their submission is the concern that the proposed rules are too broad, and will capture transactions or series of transactions that would not be considered aggressive tax planning. In addition, they noted that the rules were unclear as to what constitutes a reportable or notifiable transaction. As a consequence, this will increase administration and costs for both the CRA and taxpayers in a way that does not provide valuable incremental information to the CRA.

The Amended Proposals tweak some of the earlier proposed rules in order to addresses some of the concerns raised by the Joint Committee and others, however fall short of addressing the more substantive issues raised.

Specific Concerns with the Proposed Reportable Transaction Amendments

Under the current rules, the definition of an “avoidance transaction” excludes transactions that may reasonably be considered to have been undertaken or arranged primarily for bona fide purposes other than to obtain the tax benefit, thereby excluding transactions that are primarily commercial in nature. The new test will extend to any transaction if it may reasonably be considered that one of the main purposes of the transaction, or of a series of transactions of which the transaction is a part, is to obtain a tax benefit. According to the Joint Committee, this change is significant and somewhat problematic in that it does not differentiate between permissible and aggressive tax benefits. As a consequence, routine tax planning will be captured.

Furthermore, the new test has concerning implications for series of transactions, as it means that an individual, tax motivated transaction has the potential to make an entire series of transactions reportable regardless of the importance of the individual transaction to the series as a whole or the scope of tax benefit provided by the individual transaction. However, it will be difficult for advisors to identify or otherwise know that an innocuous transaction, that is not an avoidance transaction itself, also forms part of a series of transactions that includes an avoidance transaction. This is particularly concerning where an advisor only deals with a subset of the transactions. The Amended Proposals mitigate multiple reporting obligations among employees and partners of the same advisor, with respect to notifiable transactions, however that deeming provision does not apply to reportable transactions. 

The Joint Committee accurately notes the key problem with the proposed definition of an avoidance transaction is the lack of a “materiality” element to the test. The lower threshold purpose test will lead to a reporting requirement in many situations, even where the tax benefit is insignificant. Accordingly, the Joint Committee recommends that a de minimis test or other filter be applied in an effort to reduce overbreadth and exclude minor transactions. This approach is suggested in light of concerns about the administrative burden the proposed legislation will place on tax authorities as well as the compliance burden on taxpayers, especially smaller businesses.

Specific Concerns with the Proposed New Notifiable Transactions

The Joint Committee also raises concerns with regard to the implementation of “notifiable transactions” in the proposed legislation. A sample notifiable transaction list was released alongside the draft legislation, however, there is uncertainty regarding implementation of the new rules in terms of when they will come into effect as well as when and how new notifiable transactions will be designated and publicised.

If advice provided on transactions entered into in early 2023 would be captured by these provisions, given that the new legislation will apply to transactions entered into after 2022, advisors may be faced with a reporting requirement even if the said transaction was not a notifiable transaction when the advice was provided.

The use of the phrase “substantially similar” in the definition of a notifiable transaction in proposed paragraphs 237.4(2)(a) and (b) will also lead to confusion in determining what needs to be reported. The Joint Committee’s recommendation is for careful and consistent drafting that clearly describes the tax avoidance issue and tax consequences, along with additional guidance to be provided from a practical perspective for each designated transaction. There is also a need for a formal updated list of notifiable transactions and a process to inform tax advisors and the public of any changes.

Additional Concerns Applicable to Both Regimes

The 45-day deadline for reporting is a very short window and does not fall within the typical compliance time frame for reporting to CRA. Returns are filed within a fixed period after a year-end and most elections accompany the return. Having one-off transaction reporting throughout the year will lead to missed deadlines and increase the costs of professional services.

The proposed implementation date does not provide the reasonable amount of time required to comply with these rules. Some taxpayers will also automatically be in breach of the rules when they become law, which could lead to further commercial consequences for taxpayers.

The Joint Committee also critiqued the broad definition of an “advisor” under both sets of proposed rules. As defined under the proposed legislation, it casts an extremely wide net, and some “advisors” may not realize that they will have a requirement to report, but will nevertheless be subject to a potential penalty if they fail to do so. Some transactions may involve multiple advisors employed by different firms or companies, leading to uncertainty between them as to which elements of the work may create reporting requirements, whether individual elements of the plan have been implemented at all, and other challenges. These types of circumstances will also lead to the unnecessary requirement for multiple reporting. The original rules for reportable transactions placed the reporting requirement at the firm level as opposed to on individual employees. The Amended Proposals revert to firm level reporting for notifiable transactions but not for reportable transactions. The Joint Committee accurately notes that the new legislation may give rise to inconsistencies due to the different knowledge levels of each advisor.

Timeline for Implementation

The Amended Proposals extended application of these changes to transactions entered into after 2022, which gives additional time for implementation. A second consultation period following the Amended Proposals is open until September 20th, 2022.

Key Takeaways

Advisors must be aware of these proposed reporting and disclosure requirements and adjust their processes accordingly. Failure to properly report carries significant penalties and may prejudice clients’ limitation periods for tax assessments.

Advisors implementing or assisting in the implementation of any transactions should confirm with the client’s tax advisor as to whether the transaction is a reportable transaction or a notifiable transaction.

Businesses or individuals that intend to undertake transactions for tax planning purposes should be aware that many of their transactions will be reported to the CRA and may be subject to additional scrutiny. Where they undertake a reportable or notifiable transaction, there will likely be additional compliance costs associated with complying with their reporting obligations.
