Capital gains can push you into a higher tax bracket, which changes the percentage of tax you pay on your next dollar of income. In Canada, only 50% of your capital gains are taxable (called the inclusion rate), but this amount is added to your other income for the year. If your total income crosses into a higher bracket, your marginal tax rate increases, affecting not just your capital gains but also your salary, investment income, and other earnings. Understanding this relationship helps you plan asset sales strategically and avoid unexpected tax bills. Let's look at how this works and what you can do about it. Your marginal tax rate is the tax rate you pay on the last dollar of income you earn. It's important because it tells you how much tax you'll owe on any new income, including capital gains. Canada's tax system uses progressive tax brackets. The more you earn, the higher your marginal rate. In 2026, depending on your province, marginal rates range from roughly 20% on the first chunk of income to over 50% on income above certain thresholds.
Yes. Capital gains are added to your other income after applying the 50% inclusion rate. If this brings your total income above a bracket threshold, your marginal tax rate increases, and you'll pay tax on the gain at that higher rate.
Your marginal rate is the tax on your last dollar of income; your average rate is total tax divided by total income. When capital gains are added to your income, they're taxed at your marginal rate, not your average rate. This is why understanding your marginal rate matters.
Common strategies include spreading gains across multiple years, holding investments in a TFSA (where gains aren't taxed), offsetting gains with capital losses, making an RRSP contribution to reduce taxable income, or donating appreciated securities to charity instead of selling them.
The 50% inclusion rate makes capital gains more favorable than regular income, but gains can still trigger bracket creep. Only half the gain is added to your income, but even that can push you into a higher bracket if you're already near the threshold.
Use the CRA's tax bracket tables for your province or use a Marginal Tax Rate Calculator to input your expected income. Your rate depends on your total income for the year and where it falls in your province's tax brackets.
