The Problem of Corporate Tax Rate Hikes

Why it’s nearly impossible to avoid causing more harm than good
Are Canadian corporations paying their share? Well, what is their share? And before we go there, just how much are Canadian corporations paying?
According to Statistics Canada, in the second quarter of 2024 the federal government received $221 billion from all income tax revenues (excluding CPP and QPP). Provincial governments took in another $104 billion, and local (municipal) governments got $21 billion. Using those numbers, we can (loosely) estimate that all levels of government raise somewhere around $1.38 trillion annually.

If you’re curious (and I know you are), that means taxes cost each man, woman, and child in Canada $33,782 each year. Trust me: I feel your pain.
Based on Statistics Canada data from 2022 (the latest comparable data available), we can also say that roughly ten percent of those total revenues come from corporate taxes at both the federal and provincial levels.
Keep that 10:90 corporate-to-personal tax revenue ratio in mind. Because what if raising the corporate tax rate by, say, five percent ends up driving businesses to lay off even one percent of workers? Sure, you’ll take in an extra $7 billion in corporate taxes, but you might well lose the $12 billion in personal income taxes those laid-off workers would have paid.
How Much Should Corporations Pay?
Ok. So how should we calculate a business’s fair share? Arguably, a single dollar’s worth of business activity is actually taxed over and over again:
- When a corporation earns revenue, it’s taxed on its profits.
- Any remaining profit may be distributed to shareholders in the form of dividends. Shareholders, of course, will pay income tax on those dividends.
- Corporations pass on part of the tax burden to consumers through higher prices. When consumers pay those higher prices, a part of every dollar they spend is indirectly taxed through the corporation’s price adjustments.
- Employee wages paid from after-tax corporate profits are taxed yet again.
- Shareholders may eventually realize capital gains when they sell their shares. These gains are, naturally, also taxed.
I guess the ideal system would identify a corporate tax rate that takes all those layers into account to ensure that no single individual’s labor and contribution should carry an unreasonable burden. I’ll leave figuring out how to build such a system to smart people.
Does “Soaking Rich Corporations” Actually Work?
Do higher corporate taxes actually improve the lives of Canadians? Spoiler alert: it’s complicated.
Government policy choices generally come with consequences. From time to time, those will include actual solutions for serious problems. But they usually leave their mark in places of which lawmakers were initially barely aware existed.
Here’s where we get to explore some of those unintended consequences by comparing economic performance between provinces with varying corporate tax rates. Do higher rates discourage business investment leading to lower employment, economic activity, and incoming tax revenues? In other words, do tax rate increases always make financial sense?
To answer those questions, I compared each province’s large business tax rate with four economic measures:
- Gross domestic product per capita
- Business gross fixed capital formation (GFCF – the money businesses invest in capital improvements: the higher the GFCF, the more confidence businesses have in their long-term success)
- Private sector employment rate
- My own composite economic index (see this post)
Using four measures rather than just one or two gives us many more data points which reduces the likelihood that we’re looking at random statistical relationships. Here are the current provincial corporate tax rates for large businesses:
If we find a significant negative correlation between, say, higher tax rates and outcomes for all four of those measures, then we’d have evidence that higher rates are likely to have a negative impact on the economy (and on the human beings who live within that economy). If, on the other hand, there’s a positive correlation, then it’s possible higher taxes are not harmful.
When I ran the numbers, I found that the GDP per capita has a strong negative correlation with higher tax rates (meaning, the higher the tax rate, the lower the GDP). GFCF per capita and the private sector employment rate both had moderately negative correlations with higher taxes, and my own composite economic index had a weak negative correlation. Those results, taken together, strongly suggest that higher corporate tax rates are indeed harmful for a province’s overall economic health.
Here’s a scatter plot that illustrates the relationship between tax rates and the combined outcome scores:
Alberta, with the lowest tax rate also has the best outcomes. PEI, along with New Brunswick and Nova Scotia, share the high-tax-poor-outcome corner.
I guess the bottom line coming out of all this is that the “rich corporations aren’t paying their share” claim isn’t at all simple. To be taken seriously, you’d need to account for:
- The true second-order costs that higher corporate taxes can impose on consumers, investors, and workers.
- The strong possibility that higher corporate taxes might cause more harm to economies than they’re worth.
- The strong possibility that extra revenues might just end up being dumped into the general pool of toxic government waste.
Or, in other words, smart policy choices require good data.

Federal government’s accounting change reduces transparency and accountability

From the Fraser Institute
By Jake Fuss and Grady Munro
Carney’s deficit-spending plan over the next four years dwarfs the plan from Justin Trudeau, the biggest spender (per-person, inflation-adjusted) in Canadian history, and will add many more billions to Canada’s mountain of federal debt. Yet Prime Minister Carney has tried to sell his plan as more responsible than his predecessor’s.
All Canadians should care about government transparency. In Ottawa, the federal government must provide timely and comprehensible reporting on federal finances so Canadians know whether the government is staying true to its promises. And yet, the Carney government’s new spending framework—which increases complexity and ambiguity in the federal budget—will actually reduce transparency and make it harder for Canadians to hold the government accountable.
The government plans to separate federal spending into two budgets: the operating budget and the capital budget. Spending on government salaries, cash transfers to the provinces (for health care, for example) and to people (e.g. Old Age Security) will fall within the operating budget, while spending on “anything that builds an asset” will fall within the capital budget. Prime Minister Carney plans to balance the operating budget by 2028/29 while increasing spending within the capital budget (which will be funded by more borrowing).
According to the Liberal Party platform, this accounting change will “create a more transparent categorization of the expenditure that contributes to capital formation in Canada.” But in reality, it will muddy the waters and make it harder to evaluate the state of federal finances.
First off, the change will make it more difficult to recognize the actual size of the deficit. While the Carney government plans to balance the operating budget by 2028/29, this does not mean it plans to stop borrowing money. In fact, it will continue to borrow to finance increased capital spending, and as a result, after accounting for both operating and capital spending, will increase planned deficits over the next four years by a projected $93.4 billion compared to the Trudeau government’s last spending plan. You read that right—Carney’s deficit-spending plan over the next four years dwarfs the plan from Justin Trudeau, the biggest spender (per-person, inflation-adjusted) in Canadian history, and will add many more billions to Canada’s mountain of federal debt. Yet Prime Minister Carney has tried to sell his plan as more responsible than his predecessor’s.
In addition to obscuring the amount of borrowing, splitting the budget allows the government to get creative with its accounting. Certain types of spending clearly fall into one category or another. For example, salaries for bureaucrats clearly represent day-to-day operations while funding for long-term infrastructure projects are clearly capital investments. But Carney’s definition of “capital spending” remains vague. Instead of limiting this spending category to direct investments in long-term assets such as roads, ports or military equipment, the government will also include in the capital budget new “incentives” that “support the formation of private sector capital (e.g. patents, plants, and technology) or which meaningfully raise private sector productivity.” In other words, corporate welfare.
Indeed, based on the government’s definition of capital spending, government subsidies to corporations—as long as they somehow relate to creating an asset—could potentially land in the same spending category as new infrastructure spending. Not only would this be inaccurate, but this broad definition means the government could potentially balance the operating budget simply by shifting spending over to the capital budget, as opposed to reducing spending. This would add to the debt but allow the government to maneuver under the guise of “responsible” budgeting.
Finally, rather than split federal spending into two budgets, to increase transparency the Carney government could give Canadians a better idea of how their tax dollars are spent by providing additional breakdowns of line items about operating and capital spending within the existing budget framework.
Clearly, Carney’s new spending framework, as laid out in the Liberal election platform, will only further complicate government finances and make it harder for Canadians to hold their government accountable.

Carney poised to dethrone Trudeau as biggest spender in Canadian history

From the Fraser Institute
By Jake Fuss
The Liberals won the federal election partly due to the perception that Prime Minister Mark Carney will move his government back to the political centre and be more responsible with taxpayer dollars. But in fact, according to Carney’s fiscal plan, he doesn’t think Justin Trudeau was spending and borrowing enough.
To recap, the Trudeau government recorded 10 consecutive budget deficits, racked up $1.1 trillion in debt, recorded the six highest spending years (per person, adjusted for inflation) in Canadian history from 2018 to 2023, and last fall projected large deficits (and $400 billion in additional debt) over the next four years including a $42.2 billion deficit this fiscal year.
By contrast, under Carney’s plan, this year’s deficit will increase to a projected $62.4 billion while the combined deficits over the subsequent three years will be $67.7 billion higher than under Trudeau’s plan.
Consequently, the federal debt, and debt interest costs, will rise sharply. Under Trudeau’s plan, federal debt interest would have reached a projected $66.3 billion in 2028/29 compared to $68.7 billion under the new Carney plan. That’s roughly equivalent to what the government will spend on employment insurance (EI), the Canada Child Benefit and $10-a-day daycare combined. More taxpayer dollars will be diverted away from programs and services and towards servicing the debt.
Clearly, Carney plans to be a bigger spender than Justin Trudeau—who was the biggest spender in Canadian history.
On the campaign trail, Carney was creative in attempting to sell this as a responsible fiscal plan. For example, he split operating and capital spending into two separate budgets. According to his plan’s projections, the Carney government will balance the operating budget—which includes bureaucrat salaries, cash transfers (e.g. health-care funding) and benefits (e.g. Old Age Security)—by 2028/29, while borrowing huge sums to substantially increase capital spending, defined by Carney as anything that builds an asset. This is sleight-of-hand budgeting. Tell the audience to look somewhere—in this case, the operating budget—so it ignores what’s happening in the capital budget.
It’s also far from certain Carney will actually balance the operating budget. He’s banking on finding a mysterious $28.0 billion in savings from “increased government productivity.” His plan to use artificial intelligence and amalgamate service delivery will not magically deliver these savings. He’s already said no to cutting the bureaucracy or reducing any cash transfers to the provinces or individuals. With such a large chunk of spending exempt from review, it’s very difficult to see how meaningful cost savings will materialize.
And there’s no plan to pay for Carney’s spending explosion. Due to rising deficits and debt, the bill will come due later and younger generations of Canadians will bear this burden through higher taxes and/or fewer services.
Finally, there’s an obvious parallel between Carney and Trudeau on the inventive language used to justify more spending. According to Carney, his plan is not increasing spending but rather “investing” in the economy. Thus his campaign slogan “Spend less, invest more.” This wording is eerily similar to the 2015 and 2019 Trudeau election platforms, which claimed all new spending measures were merely “investments” that would increase economic growth. Regardless of the phrasing, Carney’s spending increases will produce the same results as under Trudeau—federal finances will continue to deteriorate without any improvement in economic growth. Canadian living standards (measured by per-person GDP) are lower today than they were seven years ago despite a massive increase in federal “investment” during the Trudeau years. Yet Carney, not content to double down on this failed approach, plans to accelerate it.
The numbers don’t lie; Carney’s fiscal plan includes more spending and borrowing than Trudeau’s plan. This will be a fiscal and economic disaster with Canadians paying the price.
