The federal government recently put a key piece of their tax platform in place: an increase in the basic personal amount (BPA). This is expected to lower taxes for close to 20 million of us, and eliminate any federal tax liability for almost 1.1 million Canadians.
To deliver on this promise, the government will increase the BPA to $15,000 by 2023. On the face of it, that’s a nice, round, substantial figure, and no doubt many of us will experience tax savings. Still, to give it some proportionality and context, let’s take a closer look to understand how, when, to whom, and to what extent this will provide tax relief.
DEDUCTIONS AND CREDITS
Most non-tax professionals likely don’t pay too much attention to the difference between a tax deduction and a tax credit. Both can reduce a person’s tax bill, but in a very real sense they are applied at opposite ends of the income spectrum.
A deduction reduces the amount on which tax is calculated. Because we have a progressive personal tax system (i.e., higher rates applying to income at higher brackets), a deduction reduces tax exposure at a person’s uppermost or marginal rate.
In terms of tax credits, a non-refundable credit reduces your initially calculated tax due, whereas a refundable credit is more like a subsidy in that it is paid even if you don’t owe tax. In either case, a maximum amount is legislated for a given purpose, against which the appropriate credit rate is applied. With a few exceptions (mainly charitable and political donations), the credit rate most often is at the lowest bracket rate. For federal tax calculations the lowest rate is 15%, but a person’s own income dictates the marginal rate, which may be as much as 33%.
Connecting those dots, a deduction is generally more valuable than a credit.
The most common non-refundable credit is the basic personal amount, sometimes called the basic personal credit.
Either way, it’s referring to the same thing — effectively negating tax on income from zero up to the set level. For instance, when you file your upcoming return for the 2019 taxation year, you’ll claim this credit on your first $12,069 income. At the 15% rate, the value of the credit is $1,810.
While it may seem an obvious point, note that the amount is larger than the credit value, since it is multiplied by the credit rate. Keep this in mind as we turn our attention to the change in the amount, and contemplate the value of that change.
ENHANCED BPA
Over the course of the next four years, the BPA will be bumped beyond its usual inflation indexing until it reaches $15,000 in 2023. The rollout schedule is shown in the first three columns of the table here, reproduced from the Department of Finance backgrounder. The two right-hand columns are my own calculations for the sake of some analysis to follow.
The additional BPA will initially yield $140 in annual tax savings, rising to about $300 in 2023, as featured in official communications. In that last year, the $15,000 amount will equate to a full value for the BPA of $2,250, a 13% improvement over what current indexing would have given.
However, it will be almost four years until early 2024 tax filing when that extra $300 may be claimed. Using the approximate 2% indexing employed by the Department of Finance, that discounts back to about $277 in current dollar value.
To be clear, I’m critiquing, not criticizing; my aim is to couch expectations of the practical implications for individual and household budgets. That last point is especially important, as there are parallel changes to the spousal and eligible dependant amounts, the effect of which will be to double the impact to as much as $600 for families claiming either of those credits.
INCOME CEILING AND TIME HORIZON
Not everyone will enjoy this enhanced BPA. Extra components will be added to the BPA definition to reduce the enhancement as income enters the 29% fourth bracket, until it is eliminated for someone whose income exceeds the 33% top/fifth bracket. For 2020, those thresholds are $150,473 and $214,368. For your curiosity, a $300 loss across this range is a clawback contribution to a marginal effective tax rate of just under 0.5%.
The BPA and brackets will continue to increase each year according to the existing indexation formula, but the BPA enhancement will remain at $15,000 after 2023. This means that the value of the enhancement will continually erode each year thereafter. Using that 2% index factor as a proxy, the BPA would overtake the enhancement by about 2030. Whether this will still be a feature of our tax system a decade from now is anyone’s guess.
