How Is Inheritance Tax Calculated In Ireland

Estimate your potential Capital Acquisitions Tax (CAT) liability in Ireland

How is Inheritance Tax Calculated in Ireland? (2024 Guide)

In Ireland, inheritance tax is known as Capital Acquisitions Tax (CAT), which also covers gifts. The calculation depends on three key factors: the value of the inheritance, your relationship to the deceased, and any previous gifts/inheritances you’ve received from them.

1. Understanding the Three Tax-Free Thresholds (Group A, B, C)

Ireland operates a group-based threshold system where your relationship to the deceased determines your tax-free allowance:

Group	Relationship	Tax-Free Threshold (2024)	Tax Rate
Group A	Child (including adopted/stepchild), parent (if inheriting from child)	€335,000	33%
Group B	Brother, sister, niece, nephew, grandchild, grandparent	€32,500	33%
Group C	Other relatives, non-relatives	€16,250	33%

Important Note: Spouses and civil partners are completely exempt from inheritance tax in Ireland, regardless of the amount inherited.

2. How Previous Gifts Affect Your Threshold

The tax-free threshold is a lifetime limit. If you’ve received previous gifts or inheritances from the same person since December 5, 1991, these amounts are deducted from your current threshold.

Example: If you’re a child (Group A) who previously received €100,000 from your parent, your remaining threshold would be €235,000 (€335,000 – €100,000).

3. Special Rules for Agricultural and Business Property

Ireland offers relief for inherited agricultural land and business assets:

• Agricultural Relief: Reduces the taxable value by 90% (effectively taxing only 10% of the value)
• Business Relief: Reduces the taxable value by 90% for qualifying business assets
• Dwelling House Exemption: May apply if you inherit a home you’ve lived in for 3+ years and continue living there

4. Step-by-Step Calculation Process

1. Determine the market value of all inherited assets (cash, property, investments)
2. Identify your group (A, B, or C) based on your relationship
3. Subtract any previous gifts from your threshold
4. Calculate taxable amount = (Inheritance value) – (Remaining threshold)
5. Apply 33% tax rate to the taxable amount
6. Subtract any reliefs (agricultural, business, etc.)

5. When and How to Pay

Inheritance tax must be paid by October 31 of the year following the inheritance (or by the “valuation date” if later). Payment options include:

• Direct payment to Revenue
• Installment payments (for certain property inheritances)
• Using the inherited assets to cover the tax

Late payment penalties: Interest accrues at 0.0219% per day (8% per annum) on unpaid tax.

6. Recent Changes and Future Outlook

The 2024 thresholds represent a €10,000 increase from 2023 for Group A (from €325,000 to €335,000). Historical threshold changes:

Year	Group A Threshold	Group B Threshold	Group C Threshold
2024	€335,000	€32,500	€16,250
2023	€325,000	€32,500	€16,250
2020	€335,000	€32,500	€16,250
2015	€225,000	€30,150	€15,075

7. Common Mistakes to Avoid

• Forgetting previous gifts: Even small gifts count toward your threshold
• Undervaluing property: Revenue may challenge valuations below market rate
• Missing deadlines: Late payments trigger immediate penalties
• Ignoring reliefs: Many fail to claim agricultural/business reliefs
• Not keeping records: You’ll need documentation for all transactions

Frequently Asked Questions

Q: Do I pay inheritance tax on my parent’s home if I lived with them?

A: Possibly not. The Dwelling House Exemption may apply if:

• You lived in the home for 3+ years before the inheritance
• You don’t own/part-own another residential property
• You continue living there for 6+ years after inheritance

Q: What happens if I can’t pay the inheritance tax?

A: Revenue offers installment arrangements for property inheritances where the tax exceeds 20% of the property’s value. You’ll need to apply and may need to provide security.

Q: Are life insurance payouts subject to inheritance tax?

A: Yes, unless the policy is written under Section 72 (where the deceased paid premiums and the beneficiary is a spouse, civil partner, or child under 21).
