If the same event results in a charge to CGT and CAT (gift/inheritance tax), then the CGT can be set against the CAT.
This means that if you gift the land to someone and you have to pay CGT and they have to pay CAT, then you reduce the CAT bill by the CGT paid. If you claim this relief, the person getting the property will have to keep it for two years.
If you are selling the land directly and passing the proceeds to your children, bear in mind that children can get gifts or inheritances of up to almost €500,000 from their parents before they have to pay CAT.
