Net capital losses can be carried forward to future tax years if you have no capital gains to offset in the same year.

You cannot deduct a net capital loss directly from your income, but you can carry it forward and deduct it from capital gains in later income years.
There is no time limit on how long you can carry forward a net capital loss.
You must apply your capital losses against your capital gains in the order in which you made them. You can't choose not to apply capital losses against capital gains if you have them, however, you can choose which capital gains to deduct your losses from.
