Completing Schedule 3

If you sold or disposed of property in 2025 and your taxable capital gains for the year were more than your allowable capital losses, you have to include the difference on line 12700 of your return. To do so, you must calculate your taxable capital gains to report on line 12700 of your return using Schedule 3, Capital Gains or Losses.

For more information on how to calculate and report a capital gain or loss, see Calculating and reporting your capital gains and losses
