Revenue lets anyone receive gifts worth up to €3,000 from any one person in a calendar year with no Capital Acquisitions Tax. It applies per giver and per receiver, every year, and it does not use up the receiver's lifetime threshold.
That adds up. Two parents can give a child €6,000 a year. Two parents can give €12,000 a year to a son or daughter and their partner. Two grandparents giving €3,000 each to four grandchildren pass on €24,000 a year, and €240,000 over ten years, without touching a threshold.
