Net capital losses can only be claimed against net capital gains in a year. So if you have gains this year then yes, you can claim your losses against this income but you cannot claim more than what is allowed.
So you might want to run Review and in the Tax-Saving Opportunities it will tell you how much, if any, losses from previous years can be applied against current year gains. If you have no current year gains then the amount will continue to be carried forward to be applied in a future year.
