Stamp Duty is not chargeable on inheritances of property. The Capital Acquisitions Tax (CAT) code includes group thresholds, below which no CAT is liable. The indexed group thresholds applying to an inheritance by a grandchild for 2007 is €49,682 (Group B). However, in the case of a minor child of a deceased child (under 18 years on the date of the inheritance), a higher threshold of €496,824 (Group A) applies. Any other gifts or inheritances that might have been received within the same group by an individual since 5 December 1991 are also taken into account when applying the thresholds for the purposes of calculating CAT. If the total value of all inheritances and gifts received since this date is above the relevant threshold, then a 20% CAT will apply on the difference.
