Net capital losses (line 25300)
The maximum amount you can claim on line 25300 is your taxable capital gains (line 12700) for the year. We’ll limit your claim on line 25300 to the amount on line 12700.
When you Check & Optimize your return, we may suggest you claim a lesser amount this year. We’ll carry forward any unused amounts to next year for you. You can change the amount of losses you claim by overriding the value in the “Prior-year net capital losses” row.
Non-capital losses (line 25200)
Your non-capital losses get applied to your return only once the optimizer runs. (If you have a linked partner, this means you’ll need to finish both of your returns before these deductions get added to your own return.) We’ll use up your oldest losses first.
You can change the amount claimed by following the instructions for net capital losses, above.
