Tax expert Johnny O’Callaghan on understanding Capital Acquisitions Tax and how you can hold on to more of your hard-earned cash
Capital Acquisitions Tax (CAT) is a tax on gifts and inheritances. The amount of gifts and inheritances you can get without paying CAT depends on your relationship to the person you get them from. Relationships are grouped into three categories with different tax-free limits. Each limit applies to the total of all the gifts and inheritances you get from people in that category.

Group A: €400,000 Parent or Foster parent to child, or grandparent to child if parent has died and you are under 18
Group B: €40,000 Sibling to sibling, grandparent to grandchild, aunt or uncle to niece or nephew.
Group C : €20,000 Any relationship that is not covered in Group A or B

Tax expert Johnny O’Callaghan is founder of Ireland's first gift tax planner called taxplanner.ie. The online service is designed to help individuals and families in Ireland navigate the complexities of Capital Acquisitions Tax (CAT).
“The most common inheritance in Ireland is from parents to children, the group threshold for that is €400,000.That’s from both parents, it doesn’t matter if they’re separated you have a €400,000 limit to get tax-free inheritance from your parents over your lifetime. If you inherit any amount over that, you owe 33.3% Capital Acquisitions Tax (CAT) on that amount.
“It sounds like a lot of money, and for some families it is. If you have a large family with five children that’s a combined inheritance wealth of €2million. However if you have an only child, and you own a property in Dublin, with the housing market the way it is, it’s almost impossible to not exceed that limit. That’s something we’re seeing more now as people are generally having smaller families and property values are increasing across the country”.
There are some steps you can take to pass some of your wealth on to family members without chipping away at their tax-free inheritance limit, Johnny explains.
“There is a small gift exemption every year of €3,000 that anyone can give to anyone, regardless of relation. There’s also no limit on how many you can receive or gift each year. So I could gift 100 people €3,000 in a year if I wanted to, and I could also receive €3,000 from 100 people. It would be tax free and it wouldn’t come off any lifetime limits for family gifting.
“It’s important to remember, however, that the €3,000 needs to be paid each year, you can accrue it in your bank account and then try to give a lump sum when they reach a certain age.
“I’ve seen grandparents utilise this too, they set up a credit union account for their grandchild, they pay €3,000 into the account every year and when the child turns 18 they can receive a €118,000 lump sum tax free. That’s far more than the €40,000 gift limit on grandparent to grandchild inheritance”.
When it comes to inheritance one group of society that is particularly vulnerable are unmarried families, warns Johnny. According to the Central Statistics Office, 43% of Irish children were born outside marriage or civil partnerships in 2022. These families are at risk of losing a large portion of their wealth to Revenue as they don’t fall into traditional family inheritance categories.
“Even if you have been cohabiting with your partner for 30 years and you share five children, there is no legal recognition of your relationship, when it comes to inheritance tax. It’s possible that it may be updated in future as it becomes more of an issue as the younger demographic ages.
“For example, if you have a couple who have been living together for 10 years and share three children, if they were married and the husband dies, the wife will inherit everything tax free and be entitled to a window’s pension. If they are unmarried, she can inherit €20,000 worth of assets tax free and the rest is liable to 33.3% tax charge, that includes the house if she is not named on the mortgage”.
