Different Types of Investment Income and How Each One Is Taxed

Two investments can each pay you $1,000 and leave you with very different amounts after tax. That is because Canada does not tax all investment income the same way. What matters is not only how much you earn, but what kind of income it is.

What $1,000 Leaves You With

Here is the 2026 tax in Alberta on $1,000 of each type of income, at a middle income (about $80,000) and at the top bracket.

Type of income	Tax at about $80,000	Tax at the top bracket	Taxable income reported
Interest	$305	$480	$1,000
Eligible dividends	$102	$343	$1,380
Non-eligible dividends	$222	$423	$1,150
Capital gains	$153	$240	$500
Return of capital	$0 now	$0 now	$0 now

Interest

Interest comes from savings accounts, GICs, bonds and money market funds. It is the simplest and the most heavily taxed: every dollar is added to your income and taxed at your full rate.

On a multi-year GIC, you are generally taxed on the interest each year as it builds, even if you do not receive it until the GIC matures. Your financial institution will send a T5 slip showing the amount. This surprises many people.

Dividends and the Dividend Tax Credit

Dividends are a share of company profits paid to shareholders. The company has already paid corporate tax on that money, so the tax system gives you credit for it through two steps.

1. The gross-up. You report more than you received. A $1,000 eligible dividend is reported as $1,380.
2. The dividend tax credit. You then get a credit that reduces your tax, usually by more than the gross-up added.

Most dividends from large public Canadian companies are eligible dividends, with a 38% gross-up. Dividends from small private corporations are usually non-eligible, with a 15% gross-up and a smaller credit.

Two things to watch. Dividends from foreign companies do not get this treatment and are taxed like interest. And because of the gross-up, a $1,000 eligible dividend counts as $1,380 of income on your tax return, which can reduce income-tested benefits and trigger the OAS clawback sooner. A seemingly low tax rate can hide that cost in retirement.

Capital Gains: Half Is Taxed

A capital gain is the profit when you sell something for more than you paid. If you buy an investment for $10,000 and sell it for $15,000, your gain is $5,000. Only half of it, $2,500, is added to your income. This is called the inclusion rate, and it is 50%. A proposal to raise it was cancelled in 2025.

• You choose the timing. You pay no tax on a gain until you sell, so it can grow untaxed for years.
• Losses help. Capital losses can offset capital gains, in the same year, the three prior years, or any future year.
• Mutual funds pass gains on. A fund that sells at a profit distributes the gain to you, usually in December. You owe tax on it even if you reinvest it and sold nothing yourself.

Return of Capital

Return of capital (ROC) is exactly what it sounds like: some of your own money coming back to you. It is not income, so it is not taxed when you receive it.

It does not disappear, however. It lowers your adjusted cost base (ACB), which is what the tax system treats as the amount you paid. A lower cost means a bigger capital gain when you eventually sell. So return of capital does not eliminate the tax, it postpones it and turns it into a capital gain, which is taxed at the lower rate.

Funds Built to Be Tax-Efficient

Some funds are designed with tax in mind. The goal is not to avoid tax but to control when it arrives, so you are not paying much tax during your high-income working years and can pay it later, often at a lower rate.

T-Series funds. Offered by many fund companies, usually named T5 or T8 for a target yearly payout of about 5% or 8%. They pay you a regular monthly cash flow, largely as return of capital, so the money you receive is mostly not taxed in the year you receive it. Tax is deferred until you sell, or until the ACB reaches zero. They work in a non-registered account and offer no such benefit inside an RRSP or TFSA.

Three cautions apply. Any return of capital is your own money coming back, not investment performance, and the amount you have invested shrinks unless the fund grows faster than it pays out. Once your ACB reaches zero, further return of capital is taxed as a capital gain in the year you receive it. And a T-Series fund may also pay some taxable income, so not every payment is tax-free in the year.

Low-turnover funds. A fund that rarely sells holdings, such as many index funds, tends to pass along fewer capital gains each year, leaving more of the tax until you sell.

Why the Account Matters as Much as the Investment

• TFSA. No tax on any of it, ever, and it does not matter which type of income it is.
• RRSP and RRIF. No tax while invested, but every dollar withdrawn is taxed as regular income, even if it came from capital gains or dividends. The special treatment is lost inside these accounts.
• Non-registered. This is the only place the rules above apply, so it is where the type of income matters most.

That is why interest-paying investments are often held inside registered accounts, and dividend- or capital gain-focused investments can make more sense outside them, once registered room is used. This depends on your own situation, including your retirement income and OAS.

Where to Start

Look at your last tax slips. A T5 shows interest and dividends, a T3 shows what your mutual funds paid you, and a T5008 shows what you sold. If you have non-registered investments, see which type of income they produce and whether a different mix, or a different account, would leave you with more after tax.
