Capital Acquisitions Tax — CAT — is the Irish name for inheritance and gift tax. At 33%, it is one of the higher rates in Europe, and it has the potential to place a significant burden on the transfer of a family business or a family farm from one generation to the next.
The issue is not theoretical. I regularly encounter situations where a business owner has spent three or four decades building something valuable, and the prospect of that asset being significantly eroded by a 33% tax charge on passing it to their children creates real distress. In some cases, the tax bill on a business inheritance forces the recipient to sell part of the business — or assets outside it — simply to fund the tax liability. That is not the outcome any business founder wants.
The good news is that there are reliefs available that, properly structured and planned for in advance, can dramatically reduce or eliminate the CAT exposure on a family business transfer. The frustrating caveat is that these reliefs require preparation — some of the key conditions take years to satisfy — and they cannot be retrofitted at the point of death or at the eleventh hour.
How CAT Works
Capital Acquisitions Tax applies to inheritances (transfers on death) and gifts (transfers during life). The tax is charged on the beneficiary — the person receiving the inheritance or gift — not on the estate or the person giving it.
The tax is calculated on the taxable value of the benefit received, after deducting the applicable tax-free threshold. There are three thresholds, set by reference to the relationship between the disponer (the person making the gift or leaving the estate) and the beneficiary:
Group A — €400,000 (approximately — this figure is adjusted periodically; verify the current threshold). This applies to benefits taken by a child from a parent, and to certain benefits from a grandparent to a grandchild where the child’s parent has predeceased.
Group B — €40,000 (approximately). This applies to benefits from a sibling, niece, nephew, grandparent, or grandchild (other than the Group A grandchild scenario).
Group C — €20,000 (approximately). This applies to all other relationships — including gifts or inheritances from unrelated parties.
The threshold is a lifetime aggregate — meaning it is the total amount receivable from all benefits within the same group over the beneficiary’s lifetime. Once the threshold is exhausted, all further benefits are taxed at 33%.
For a child inheriting a family business worth €1.5 million from a parent, the first €400,000 is free of CAT. The remaining €1.1 million is taxed at 33% — a CAT liability of €363,000. Without reliefs, that is the bill.
With Business Relief or Agricultural Relief properly in place, the position can be dramatically different.
Business Relief
Business Relief is the most significant CAT mitigation tool for family business succession. It provides an 90% reduction in the taxable value of relevant business property — meaning a business worth €1.5 million is valued at only €150,000 for CAT purposes after Business Relief. The CAT on €150,000 after the Group A threshold is applied may be zero or very small.
For Business Relief to apply, the property must be “relevant business property” — broadly, shares in an unquoted trading company, or assets used in a sole trader business or partnership. The business must have been owned by the disponer for at least two years before the gift or inheritance.
The beneficiary must also retain the business property for a minimum period (six years) after the gift or inheritance and must not dispose of it during that period without reinvesting the proceeds in qualifying replacement property. If the clawback conditions are triggered — the beneficiary sells the business within six years — the relief can be partially or fully withdrawn.
Business Relief does not apply to investment companies, property holding companies, or businesses that have a significant non-trading element. The “wholly or mainly trading” test for the company, and the two-year ownership period for the disponer, are the key qualifying conditions.
Agricultural Relief
For farm businesses and agricultural land, Agricultural Relief provides the same 90% reduction in taxable value, subject to its own qualifying conditions. The key requirements are that the property is agricultural property (land, livestock, farm buildings, machinery) and that the beneficiary is a “farmer” — broadly, that at least 80% of their assets after the gift consist of agricultural property.
Agricultural Relief is particularly important in a county like Louth, where significant agricultural land values can create large CAT exposures without relief.
The Interaction of CGT and CAT
One aspect that confuses many families planning a business transfer is the interaction between CAT (inheritance and gift tax, on the beneficiary) and CGT (Capital Gains Tax, potentially on the disponer on a lifetime gift).
Where a business is transferred by way of a gift during the owner’s lifetime, the owner may be treated as disposing of the business for CGT purposes at market value — potentially triggering a CGT liability. If the transfer qualifies for Retirement Relief (as I’ve covered in my guide to Capital Gains Tax for SME owners), that CGT liability may be eliminated. But both taxes need to be considered simultaneously in any lifetime transfer plan.
On death, there is no CGT charge for the deceased — the estate passes assets at probate value without CGT. The beneficiary takes the asset at that value for CGT purposes, meaning the gain accrued during the deceased’s lifetime is effectively extinguished. This “CGT uplift on death” makes death transfers more CGT-efficient than lifetime gifts in many cases — but CAT applies regardless.
The optimal structure for a family business transfer depends on the relative values of the CGT and CAT reliefs available, the ages and health of the parties, and the family’s specific financial circumstances. There is no universal answer, and the planning should be done with full professional advice.
Why Planning Must Start Early
The conditions for both Business Relief and Retirement Relief include minimum ownership and involvement periods — two years for Business Relief, ten years for Retirement Relief. These are not satisfied by restructuring the business the year before a transfer.
Similarly, the Group A CAT threshold is a lifetime aggregate. If a parent has already made significant gifts to a child during their lifetime, those gifts erode the threshold available when the business is eventually transferred. Understanding the cumulative CAT exposure requires tracking all benefits received since 5 December 1991 (the relevant date for the current CAT system).
Other planning considerations — will drafting, shareholder agreements, life assurance to fund CAT liabilities, business structuring to ensure the qualifying conditions are met — all require time to implement properly. Business Relief and Retirement Relief are among the most valuable tax reliefs that Irish business owners regularly miss, and both require advance preparation.
The businesses I see where succession planning has worked well are the ones where the conversation started when the founder was in their fifties. The ones I see where it has gone badly are the ones where the conversation started with a phone call from a solicitor. For more on succession tax planning and related topics, see our taxation guides.
