Good afternoon, Chair Gould and members of the committee.
Thank you for the opportunity to speak today. As a tax researcher, I conduct behavioural tax research in which I design surveys and experiments grounded in psychology theories to understand how individuals make tax-related decisions, including income tax reporting decisions. I would like to share with you some findings from three of my research projects.
The first project, completed in 2023, investigates how the general public responds when they learn that wealthy individuals go unpunished after engaging in aggressive tax avoidance using tax havens. The general public perceives aggressive tax behaviour as tax evasion. I designed an experiment using a scenario based on the KPMG Isle of Man tax scheme, which may be familiar to you. I was simply interested in knowing whether observers' tax compliance intentions would differ if a wealthy tax evader was punished versus unpunished. The results showed that observers' tax compliance intentions increased when a tax evader was punished versus unpunished. Put differently, failure for a tax authority to punish what members of the general public perceive to be an unfair tax violation in a tax haven setting has a negative impact on everyday taxpayers' compliance attitudes.
Members of the general public tend not to understand the distinction between aggressive tax avoidance and tax evasion. To them, the perception is that wealthy taxpayers are doing something wrong and are getting an unfair advantage by paying less taxes than they should. Thus, for everyday taxpayers who have opportunities to engage in tax reporting non-compliance, such as from side hustles or upselling World Series tickets, there are negative spillover effects on them from media stories about tax havens in which perpetrators of egregious tax avoidance schemes go unpunished.
A second project I did, completed in 2021, analyzed a 10-year sample of all media conviction notices published by the Canada Revenue Agency, or CRA. For purposes of this presentation, I will simply note that there were zero reported convictions for offshore tax evasion. That number may have changed a little bit since then, but not by much.
A third project I have recently started required me to make an access to information request from the Public Prosecution Service of Canada, or PPSC. I requested records about the charges laid by the PPSC relating to the Income Tax Act from January 2010 through May 2025. High-level findings from this data reveal that only about one-third of the charges laid by the PPSC relate to tax evasion in some form, in section 239 of the Income Tax Act. The remaining charges are for failure to file a tax return, in section 238 of the Income Tax Act.
The number of charges overall have dropped from a high of 2,397 in 2010 to only 43 in 2023 and to 47 in 2024. Furthermore, the average number of days from tax evasion charges to sentencing is well over 2,000, and in some cases exceeds 3,000, depending on the specific provision in section 239. Thus, it can take many years for a tax evasion case, almost all of which could be domestic tax evasion, to work its way through the court system.
The takeaway from these three projects is as follows: prosecution in Canada for tax evasion is uncommon, and for offshore tax evasion appears to be virtually non-existent; prosecuting tax evasion is a very slow process; and prosecutions for tax evasion appear to have dropped drastically in recent years, which raises serious questions about the CRA's enforcement efforts. Exacerbating the situation is that the general public's perception of a lack of punishment for offshore tax evasion can have negative influences on domestic tax compliance, which is arguably a bigger issue than offshore tax evasion.
Whilst on sabbatical in 2023, I had the opportunity to work part time at the CRA in their audit, evaluation and risk branch. Overall, I was very impressed with the agency. Thus, my comments should not be misconstrued as an implied criticism of the CRA or the PPSC. Enforcement activities related to offshore tax havens require a delicate balancing act between limited enforcement resources and the risk of setting an unfavourable precedent under common law if a prosecution were to be unsuccessful.
Finally, Canada, like other countries, uses deterrence as one approach to improve tax compliance. Another approach, and one that I think Parliament might be advised to consider, is to reduce the incentives for using offshore tax havens. If incentives for using tax havens could be reduced, offshore tax activities would be curtailed and thus offshore tax non-compliance would be curtailed. Currently, corporations and high-income individuals have incentives to use tax havens because tax rates in Canada are much higher than tax rates in tax havens.
