Not A Sales Tax
Capital Gains Tax (CGT) is payable when you sell or dispose of an asset for money or money’s worth and have made a gain/profit. This means you do not have to sell an asset for a profit, it means CGT may be payable when you dispose of it either on sale or if you give it away. For example, if you sell shares of a 2nd property, CGT may be payable if the asset has grown in value. Equally, if you dispose of the asset by gifting it to your children and its value at the time of the gift was more than you paid for it, CGT may be payable.
