Inheritance tax in Ireland affects far more families than many people realise — and for blended families in particular, the rules can come as a genuine shock. Understanding the inheritance tax Ireland categories and how Capital Acquisitions Tax Ireland (CAT) applies to different relationships is essential for anyone thinking about estate planning or protecting the financial future of their loved ones.
At Money Maximising Advisors Limited, our team of expert financial advisers works with families across Dublin, Galway, and throughout Ireland to help them navigate the often complex and emotionally charged area of inheritance tax planning. Whether you’re from a traditional family structure or a blended one, understanding your obligations — and your opportunities — is the first step to protecting what you’ve worked hard to build.
What Is Capital Acquisitions Tax (CAT) in Ireland?
Capital Acquisitions Tax Ireland is the tax payable on gifts and inheritances received above certain tax-free thresholds. When someone receives an inheritance or substantial gift, Revenue assesses whether the value exceeds the applicable threshold based on the relationship between the giver and the recipient. If it does, CAT tax Ireland is applied at a flat rate of 33% on the excess amount.
The key to understanding inheritance tax Ireland is knowing which Irish inheritance tax categories you fall into — because this determines your tax-free threshold and therefore how much tax you may be liable to pay.
What Are the Inheritance Tax Categories in Ireland?
Irish inheritance tax divides beneficiaries into three distinct groups, each with its own tax-free threshold. These Irish inheritance tax categories are known as Group A, Group B, and Group C.
Group A — Parents to Children (Including Certain Step-Children)
Group A has the most generous Irish inheritance tax thresholds and applies primarily to inheritances from a parent to a child. The current Group A threshold is €335,000 (as of 2024). This means a child can inherit up to €335,000 from a parent entirely free of CAT tax Ireland.
Importantly, in some circumstances, a foster child, an adopted child, or even a stepchild may qualify for Group A thresholds — but this depends on specific legal and factual criteria. This is one of the areas where specialist inheritance tax Ireland advice is absolutely essential.
Group B — Relatives (Siblings, Nieces, Nephews, Grandchildren, etc.)
Group B applies to a broader range of family relationships, including brothers, sisters, nieces, nephews, grandchildren, and lineal ancestors other than parents. The Group B threshold is €32,500 — considerably lower than Group A, which can result in significant CAT tax Ireland liabilities for beneficiaries in this category.
For large estates, beneficiaries falling into Group B can face substantial tax bills. Proactive estate planning with the right Irish inheritance tax strategy can help mitigate this considerably.
Group C — All Others
Group C covers everyone who doesn’t fall into Groups A or B — including non-family beneficiaries, close friends, and in many cases, cohabiting partners who are not married or in a civil partnership. The Group C threshold is just €16,250.
This is particularly relevant for blended families and non-traditional family structures, where the relationships between beneficiaries and the deceased may not align neatly with the legal categories Revenue uses.

Inheritance Tax for Blended Families in Ireland
Blended families — those involving step-parents, stepchildren, and half-siblings — face some of the most complex inheritance tax Ireland scenarios. The inheritance tax on stepchildren Ireland rules, in particular, can create unexpected and significant tax liabilities.
Do Stepchildren Pay Inheritance Tax in Ireland?
This is one of the most frequently asked questions we receive. The answer depends on whether the stepchild has been legally adopted. In general:
- A legally adopted stepchild is treated as a natural child and qualifies for the Group A threshold of €335,000
- A non-adopted stepchild is generally treated as a stranger in blood (Group C) and would only have a threshold of €16,250
- In some cases, a stepchild who was treated as a child of the household may be able to make a case for Group A treatment — but this is fact-specific and requires careful legal and financial advice
The difference in Irish inheritance tax thresholds between Group A and Group C is enormous — €335,000 versus €16,250 — meaning the tax implications of a step-relationship can be extremely significant. For families with blended structures, this is an area that should never be left unaddressed.

How Much Can You Inherit Tax-Free in Ireland?
To summarise the Irish inheritance tax thresholds currently in place:
- Group A (parent to child, in most cases): €335,000
- Group B (siblings, nieces/nephews, grandchildren, lineal ancestors): €32,500
- Group C (all others, including most step-relationships and non-family): €16,250
It’s important to note that these thresholds are lifetime cumulative limits. If someone received a gift or inheritance previously, those amounts are counted against the same threshold when calculating future CAT tax Ireland liability.
Strategies to Reduce Inheritance Tax in Ireland
The good news is that with proper planning, there are effective and entirely legal strategies to reduce inheritance tax Ireland exposure. These include:
Section 72 and Section 73 Life Insurance Policies
Revenue-approved life insurance policies specifically designed to cover Capital Acquisitions Tax Ireland liabilities on death. The proceeds are payable tax-free to beneficiaries, provided the policy meets Revenue criteria.
Annual Small Gift Exemption
Each year, a person can receive gifts of up to €3,000 from any individual entirely free of CAT. Used consistently over time, this exemption can meaningfully reduce the size of a taxable estate.
Business and Agricultural Relief
Qualifying business and agricultural assets may attract 90% relief from CAT tax Ireland, significantly reducing the taxable value of these assets in an estate.
Spousal Exemption
Transfers between spouses and civil partners are exempt from inheritance tax Ireland — but this does not apply to cohabiting couples, which can create challenges in blended family situations.
