In the most recent financial year, I sold shares and crypto at a loss. In the future, I hope to use these losses to offset future capital gains; however, these gains haven't occurred yet.
My understanding is that capital losses can be held indefinitely, but am I required to declare these losses within the period they were sold, even if they aren't being used to offset any gains during this period?
If I am required to declare them, how would I do so?
Any help is appreciated, thanks in advance.
