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.

Big win for Alberta and Canada: Statement from Premier Smith

Premier Danielle Smith issued the following statement on the April 2, 2025 U.S. tariff announcement:
“Today was an important win for Canada and Alberta, as it appears the United States has decided to uphold the majority of the free trade agreement (CUSMA) between our two nations. It also appears this will continue to be the case until after the Canadian federal election has concluded and the newly elected Canadian government is able to renegotiate CUSMA with the U.S. administration.
“This is precisely what I have been advocating for from the U.S. administration for months.
“It means that the majority of goods sold into the United States from Canada will have no tariffs applied to them, including zero per cent tariffs on energy, minerals, agricultural products, uranium, seafood, potash and host of other Canadian goods.
“There is still work to be done, of course. Unfortunately, tariffs previously announced by the United States on Canadian automobiles, steel and aluminum have not been removed. The efforts of premiers and the federal government should therefore shift towards removing or significantly reducing these remaining tariffs as we go forward and ensuring affected workers across Canada are generously supported until the situation is resolved.
“I again call on all involved in our national advocacy efforts to focus on diplomacy and persuasion while avoiding unnecessary escalation. Clearly, this strategy has been the most effective to this point.
“As it appears the worst of this tariff dispute is behind us (though there is still work to be done), it is my sincere hope that we, as Canadians, can abandon the disastrous policies that have made Canada vulnerable to and overly dependent on the United States, fast-track national resource corridors, get out of the way of provincial resource development and turn our country into an independent economic juggernaut and energy superpower.”

Canada may escape the worst as Trump declares America’s economic independence with Liberation Day tariffs

MxM News
Quick Hit:
On Wednesday, President Trump declared a national emergency to implement a sweeping 10% baseline tariff on all imported goods, calling it a “Declaration of Economic Independence.” Trump said the tariffs would revitalize the domestic economy, declaring that, “April 2, 2025, will forever be remembered as the day American industry was reborn.”
Key Details:
-
The baseline 10% tariff will take effect Saturday, while targeted “reciprocal” tariffs—20% on the EU, 24% on Japan, and 17% on Israel—begin April 9th. Trump also imposed 25% tariffs on most Canadian and Mexican goods, as well as on all foreign-made cars and auto parts, effective early Thursday.
-
Trump justified the policy by citing foreign trade restrictions and long-standing deficits. He pointed to policies in Australia, the EU, Japan, and South Korea as examples of protectionist barriers that unfairly harm American workers and industries.
-
The White House estimates the 10% tariff could generate $200 billion in revenue over the next decade. Officials say the added funds would help reduce the federal deficit while giving the U.S. stronger leverage in negotiations with countries running large trade surpluses.
Diving Deeper:
President Trump on Wednesday unveiled a broad new tariff policy affecting every imported product into the United States, marking what he described as the beginning of a new economic era. Declaring a national emergency from the White House Rose Garden, the president announced a new 10% baseline tariff on all imports, alongside steeper country-specific tariffs targeting longstanding trade imbalances.
“This is our Declaration of Economic Independence,” Trump said. “Factories will come roaring back into our country — and you see it happening already.”
The tariffs, which take effect Saturday, represent a substantial increase from the pre-Trump average U.S. tariff rate and are part of what the administration is calling “Liberation Day” for American industry. Reciprocal tariffs kick in April 9th, with the administration detailing specific rates—20% for the European Union, 24% for Japan, and 17% for Israel—based on calculations tied to bilateral trade deficits.
“From 1789 to 1913, we were a tariff-backed nation,” Trump said. “The United States was proportionately the wealthiest it has ever been.” He criticized the establishment of the income tax in 1913 and blamed the 1929 economic collapse on a departure from tariff-based policies.
To underscore the move’s long-anticipated nature, Trump noted he had been warning about unfair trade for decades. “If you look at my old speeches, where I was young and very handsome… I’d be talking about how we were being ripped off by these countries,” he quipped.
The president also used the moment to renew his push for broader economic reforms, urging Congress to eliminate federal taxes on tips, overtime pay, and Social Security benefits. He also proposed allowing Americans to write off interest on domestic auto loans.
Critics of the plan warned it could raise prices for consumers, noting inflation has already risen 22% under the Biden administration. However, Trump pointed to low inflation during his first term—when he imposed more targeted tariffs—as proof his strategy can work without sparking runaway costs.
White House officials reportedly described the new baseline rate as a guardrail against countries attempting to game the system. One official explained the methodology behind the reciprocal tariffs: “The trade deficit that we have with any given country is the sum of all trade practices, the sum of all cheating,” adding that the tariffs are “half of what they could be” because “the president is lenient and he wants to be kind to the world.”
In addition to Wednesday’s sweeping changes, Trump’s administration recently imposed a 25% tariff on Chinese goods tied to fentanyl smuggling and another 25% on steel and aluminum imports—revoking previous carve-outs for countries like Brazil and South Korea. Future tariffs on semiconductors, pharmaceuticals, and raw materials such as copper and lumber are reportedly under consideration.
Trump closed his remarks with a message to foreign leaders: “To all of the foreign presidents, prime ministers, kings, queens, ambassadors… I say, ‘Terminate your own tariffs, drop your barriers.’” He declared April 2nd “the day America’s destiny was reclaimed” and promised, “This will indeed be the golden age of America.”
