Understanding Canada's tax system is
critical for Canadian investors. As the saying goes, it's not what you make, but rather what you keep. The difference between making and keeping is mostly income tax!
Our tax system is progressive, and differentiates type of income. It is also affected by your home province. Let's take a look at all of these...
Before starting, this is not an exhaustive treatment of the topic of taxes - there are entire sites dedicated to that topic. We are providing only a basic overview to help inform investment decisions.
What is Progressive Taxation?
Progressive taxation means that your income tax rate rises as your income increases. It is actually one of the least understood attributes of the Canadian tax system.
Look at the chart at the top of this page. It shows the tax rates for residents of BC during the 2025 tax year. This chart was produced by Boat Harbour Investments Ltd. and taken from the
taxtips.ca website. We recommend that site to look up more detailed rules than we can cover here, and for rates for your province.
The chart shows that BC residents earning less than $49,279 have to pay 20.06% in income taxes. For incomes between $49,279 and $57,375, the rate increases to 22.70%. This is because of provincial tax rates increasing at incomes above $49,279. At that income level, the federal portion of taxes rises 5.5%, increasing the total rate to 28.2%.
So, a BC resident having a taxable income of $55,000 this year would calculate income tax payable as:
20.06% of $49,279 = $9,885.36 plus
22.7% of $8,096 =$1,837.79, plus
28.2% of $5,721 = $1,613.22
for a total of $13,336.37
This highest rate (here 28.2%) is called your
Marginal Tax Rate (MTR). Every extra dollar of income earned accumulates tax payable at this rate.
How is my Paycheque Deduction Calculated?
Payroll software takes the gross amount of a paycheque, and multiplies it by the number of scheduled paycheques in a year. If, for example, you are paid every 2 weeks, the gross is multiplied by 26. The standard Personal Tax Credits are subtracted. The calculated number is your estimated taxable income. Payroll calculates your tax payable on that income level, and divides it by the number of paycheques. That's your regular deduction.
Then you work overtime. It seems like you end up paying mostly tax with the extra income. That's because the calculation is duplicated, with a higher income per paycheque. Working 8 hours of overtime weekly at $25 an hour would give an extra $5000 annual income. This extra income is taxed at the highest MTR calculated above. It's possible that the extra income could put you in a higher tax bracket. That higher rate would then be applied to the overtime portion of your weekly cheque!
As an extra tip, consider filling in the payroll form every year claiming additional deductions. The ideal tax time result is not having a big return. Getting a large return means that you leant your money to the government interest-free throughout the year.
Other Forms of Income
Income from interest bearing assets is taxable at the individual's MTR. The same applies to most other types of income, including rentals. The exceptions are eligible Capital Gains and Dividends from eligible Canadian Corporations described below.
There are a few watch outs to consider for average Canadians. Some examples of these follow:
Capital Gains from the sale of your own home are not taxable. The exception to this rule is if the CRA determines that renovating houses for short term profit is your occupation. In this case, the increase in the home's value is treated as business income.
Buying and selling of bonds can be treated like investing in stocks, if the bonds are not held long-term. Trading in bonds generates capital gains and losses. Buying a bond to hold it for the duration of the bond implies purchasing a known cash payout over a known period of time. The CRA determines this to be an interest bearing investment, not a Capital one.
Capital Gains
Capital Gains and Losses are defined as the gains or losses from the sale of capital assets. They are given preferential tax treatment as the government wants to reward Canadians who invest in the economy.
Capital gains are included in income at a 50% rate for the first $250k in gains. Above that level, the "inclusion" rate rises to 66.6% starting in 2026.
There are additional benefits for those who are significant investors in small Canadian corporations.
Dividends
Dividends are quarterly or annual payments a company makes to the shareholders. Distributing profits as dividends is one way to increase the perceived value of owning the company's shares.
One of the principles of the Canadian tax system is that the same income should not be taxed twice. Dividends come from after tax income generated by the company, so the company has already paid taxes on the income. The tax rate for company income is substantially lower than any individual's MTR.
There is a complex calculation applied to dividend payments intended to approximate the amount of taxes already paid by the company. The net result is that dividends are taxed significantly less than other forms of income, other than capital gains.
Summary
This introduction to the tax system provides a conceptual understanding, allowing the investor to consider the tax implications of an investment strategy.
