Revenue lets anyone give anyone gifts of up to €3,000 in a calendar year with no Capital Acquisitions Tax. Each parent can give €3,000 to a child every year, so two parents can give €6,000. Grandparents can each give €3,000 too.
Gifts within the exemption do not count against the child's lifetime threshold for gifts from their parents, which Budget 2027 raised to €420,000 for gifts taken on or after 7 October 2026. In Revenue's own example, two parents giving €3,000 each a year for 10 years pass on €60,000 with no gift tax and the threshold untouched.
