A new study from the Fraser Institute is pushing back against a long-standing narrative in Canadian public discourse: that the country’s richest households aren’t pulling their weight at tax time. The numbers, researchers say, tell a strikingly different story.
According to the report, the top 20 percent of income-earning families in Canada households bringing in more than $270,472 annually are responsible for 65.3 percent of all personal income taxes collected and 58.3 percent of total tax revenue across the country. That’s while accounting for roughly half of all family income earned nationally, at 49.5 percent.
In other words, Canada’s highest earners are paying out at a rate that is nearly 16 percentage points higher than what their income share alone would suggest a gap the report’s authors describe as a clear indicator of how steeply progressive the Canadian tax system already is.
“The idea that top earners don’t pay their ‘fair share’ of taxes ignores the evidence that these families pay a disproportionately large share of the total tax bill,” said Jake Fuss, director of fiscal studies at the Fraser Institute and co-author of the report. “Canadians should be aware that the country’s tax system is already progressive, and calls to raise taxes further on top earners can have unintended economic consequences.”
The report breaks down the earnings-versus-taxes relationship across five income brackets, offering a detailed picture of who pays what.
At the lower end of the scale, families earning between $0 and $63,068 the bottom fifth of earners contribute just 1.7 percent of total tax revenue, while representing 4.3 percent of all family income. Moving up the ladder, households earning between $63,089 and $111,354 account for 9.3 percent of total income but contribute 6.5 percent in taxes.
The middle tier families earning between $111,355 and $171,298 contributes 12.7 percent of taxes while earning 14.6 percent of income. The second-highest bracket, covering incomes from $171,299 to $270,472, pays 20.8 percent of taxes against a 22.3 percent income share.
The top 20 percent stands alone as the only group that contributes a share of taxes exceeding its share of income and by a substantial margin.
The study also revisits what happened the last time the federal government moved to increase taxes on high earners. When the higher 2016 income tax rate was announced in 2015, many top earners moved quickly to shift their income forward into the prior tax year to avoid the new rate a legal but significant behavioural response.
As a result, average reported income among top earners spiked in 2015 and then fell sharply in 2016. Beyond that timing manoeuvre, affected taxpayers also turned to tax planning, income shifting, and other avoidance strategies to limit their exposure to the new rate.
The authors argue this pattern demonstrates that tax hikes on high-income earners don’t always generate the anticipated revenue and can sometimes backfire economically.
Internationally, Canada’s tax rates on high earners are already among the steepest in the developed world. The report notes that Canada holds the fifth-highest combined personal income tax rate among the 38 member countries of the Organisation for Economic Co-operation and Development (OECD).
This ranking, the report’s authors warn, has real consequences for the country’s ability to attract and retain skilled professionals. Doctors, scientists, senior managers, and software engineers all highly mobile in today’s global labour market may increasingly look south of the border or to other nations with more favourable tax environments.
“Raising taxes on high-income earners in particular renders Canada a less appealing destination for highly skilled workers,” the report states, framing competitiveness not just as an economic concern but as a long-term talent and innovation challenge for the country.
The Fraser Institute’s findings are likely to add fresh fuel to an ongoing and often heated debate about tax equity in Canada. Proponents of higher taxes on top earners argue that wealth concentration justifies a larger contribution, while critics including the report’s authors say the focus should be on what earners actually pay relative to what they earn.
The report makes the case that framing tax fairness around income share is the appropriate standard, and by that measure, Canada’s top earners are already bearing a heavier load than any other group.
Whether that framing resonates with policymakers and the public remains to be seen but the data, at minimum, complicates the popular assumption that the wealthy are getting off easy.
