How Canadian capital gains tax works
In Canada, only a portion of your capital gains is added to your taxable income. This is called the inclusion rate. The current rate for individuals is 50%.
So if you have a $10,000 capital gain and your marginal tax rate is 30%, you'd owe about $1,500 in tax ($10,000 × 50% × 30%), leaving $8,500 after tax.
Adjusted Cost Base (ACB) is what you originally paid, plus any commissions, plus any reinvested distributions. WealthWatch tracks ACB automatically as you buy, sell, and receive distributions, so when you sell, your realized gain is already calculated.
Capital losses can be used to offset capital gains in the same year, carried back 3 years, or carried forward indefinitely. WealthWatch flags superficial losses (where you buy the same security within 30 days) so you don't accidentally disallow your own loss.
