When a tax cut isn't quite what it sounds like
Sometimes it seems like the government instinct to message track everything until it is unrecognizable in human language is an unstoppable force, like some kind of linguistic quicksand. That’s how we get press releases like “Building Canada strong by investing in sewer infrastructure in the District of Saanich.”1
But then we get an occasional ray of light from the good people at Finance Canada, who remind us that it remains possible to publish interesting, useful, and politically neutral information. At least when mandated by law.
One of the first steps the Carney government took after the 2025 election, back in May 2025, was an “affordability package” that included a rate cut for the first personal income tax bracket (up to $57,375 in 2025) from 15% to 14%. That cut was initially introduced through a Ways and Means Motion, and then included in Bill C-4 which eventually received royal assent in March 2026.
That tax rate isn’t only what people pay to the federal government on that chunk of their income, it’s also what’s used to set the value of non-refundable tax credits. So changing the rate means both less tax paid and less tax relief from those credits. So the Parliament of Canada, in their wisdom, introduced a clause in Bill C-4 that requires the Minister of Finance to report on the net impact of these changes together.2
That report was released last week. And it’s a short, clear read about how these changes together affect different policies and different groups of Canadians.
When the tax cut was introduced, the news release said that “the bulk of tax relief will go to those with incomes in the two lowest tax brackets.” This report confirms that - after taking into account the lower value of the tax credits, 80% of the dollar value goes to the first two tax brackets.
That sounds redistributive, until you remember that the 2nd tax bracket goes up to $117K. (The median individual income of all tax filers is around $44K). When you look at it on a per capita basis, the net benefit is much higher for higher earners.
This isn’t some kind of trickery, and it doesn’t make this regressive. It’s just the arithmetic. By nature, someone earning say, that $44K income will be getting that 1% break on $44K of income ($440, before the weaker effect of the credits), while anyone in a higher bracket is getting the full $580.
But it does mean that any case where tax credits are being used as a policy lever, they just got about 7% less effective. The caregiver amounts are now worth $19 million less overall. Tuition amounts are worth $132 million less.
Especially with the a “top up” credit for edge cases, people across all brackets in nearly all situations are going to be paying less tax as a result. But if the effect was going the other way, you know we would gear about how we are building Canada strong and making life affordable for Canadians by increasing the value of these tax credits.
Nothing but respect for the people finding a little joy by pushing through “Atlantic Canadian companies dive into new markets at Aquaculture UK” 🥽
The legislative language is “ The Minister of Finance must prepare a report that outlines the impact of reducing the personal income tax rate provided in paragraph 117(2)(a) of the Income Tax Act on all tax credits that are calculated using the appropriate percentage as defined in that Act.”
