On 25 June 2020, the Irish Revenue published an eBrief No. 124/20 on a Tax and Duty Manual part 19-02-05 related to treatment of capital losses. This manual describes the principles of allowable losses, and clarifies that where an allowable loss arises in a chargeable period and there is no chargeable gain against which it may be offset in that chargeable period, there is no requirement for a person to include the loss in a tax return for the chargeable period in which the loss arises. All the rules used in computing gains apply in computing losses.
