The death of a shareholder in a private company can create significant tax, commercial, and succession challenges for family businesses and owner-managed companies.
It’s surprising how many private companies have never thought about what happens if one of the shareholders died.
Beyond the immediate emotional and operational shock, the transfer of shares on death can trigger “CAT” (Capital Acquisitions Tax) liabilities, valuation disputes, and uncertainty around the future ownership and control of the business.
The remaining shareholders may also wonder if the company can “look after” the family of the deceased shareholder and what the tax consequences/reliefs may be.
Waiting until the event has already happened is an interesting time to be trying to scramble for answers.
So, What Happens to Shares When a Shareholder Dies?
When a shareholder dies, their shares do not automatically pass to the surviving shareholders. This seems to be a common misconception. The shares form part of the deceased’s estate.
This means the shares will pass either:
- under the terms of their will, or
- under the rules of intestacy where no will exists.
This means surviving shareholders may suddenly find themselves in business with spouses, children, or extended family members who know nothing about the business and were never intended to be involved.
Equally, beneficiaries may inherit shares that are valuable on paper, but difficult to convert into immediate cash.
Common Succession Planning Options
Share Buy-Backs
One of the most common succession solutions is a share buy-back.
Under a share buy-back arrangement, the company purchases the deceased shareholder’s shares from the estate. This can:
- provide liquidity to beneficiaries,
- avoid fragmented ownership,
- allow surviving shareholders to retain control,
- prevent unwanted third parties becoming shareholders.
From a tax perspective, however, careful structuring is essential.
A share buy-back may either be treated:
- as a capital transaction, or
- as an income distribution.
Where the statutory conditions are satisfied, including a so called “trade benefit test”, capital treatment may apply, potentially producing a more favourable tax outcome. Where those conditions are not met, the proceeds may instead be taxed as a dividend at significantly higher rates.
Shareholder Agreements & Pre-Emption Rights
It would always be recommended to have a Shareholders’ Agreement, and particularly so where shareholders are not spouses or immediate family members.
Many Shareholders’ Agreements contain pre-emption provisions or cross-purchase arrangements which provide surviving shareholders with the option to acquire the deceased shareholder’s shares before they pass to third parties or beneficiaries.
These arrangements may be funded through shareholder protection or key person policies, depending on whether the arrangement is structured personally between shareholders or through the company.
However, careful legal and tax drafting is essential to ensure that such arrangements do not themselves create unintended tax consequences.
Passing Shares to Family Members
In some cases, shares simply do pass to spouses or family who retain ownership.
While this preserves family wealth and continuity, it can create governance problems where ownership becomes increasingly fragmented over generations.
Special CAT Rules for Private Companies
Where shares in a private company pass on death, the valuation rules become highly relevant.
Section 27 of CATCA 2003 governs the valuation of shares in private companies including those controlled by the donee or successor for capital acquisitions tax purposes.
The legislation contains anti-avoidance provisions designed to prevent taxpayers from reducing CAT valuations through artificially fragmented shareholdings.
A “private company” for these purposes is broadly a company:
- under the control of not more than five persons, and
- not a company falling within Section 431 TCA 1997.
The legislation adopts a broad definition of “control”.
A person may control a company where they are entitled to:
- more than 50% of voting rights,
- control of the board,
- more than 50% of dividends,
- or 50% or more of the issued share capital.
Why Section 27 Matters (a lot)
Ordinarily, minority shareholdings attract valuation discounts because they lack control and marketability.
However, Section 27 can override these normal valuation principles.
When shares are inherited, the legislation requires the inherited holding to be aggregated with:
- the beneficiary’s existing shares,
- shares held by relatives,
- shares held by partners in a partnership.
If, after aggregation, the beneficiary and connected persons effectively control the company, the inherited shares may be valued as part of a controlling interest rather than as a minority holding.
This can significantly increase the taxable value for CAT purposes.
The definition of “relative” under the legislation is very extensive. Many family businesses are therefore unintentionally caught by these aggregation rules.
Example: Increased CAT Valuation on Death
Consider a private company with the following ownership:
- A — 10%
- B (A’s father) — 30%
- C (B’s cousin) — 30%
- D (C’s wife) — 30%
The value of A’s 10% holding as a minority interest is €55,000.
The value attributable to the 10% holding if it were part of a controlling shareholding however would be €90,000.
A dies and leaves their 10% shareholding to B.
B already has their own 30% and they’ve also now just inherited another 10% from A. But Section 27 requires aggregation with relatives. Under the wide CAT definition of “relative”, the holdings of B’s cousin and the cousin’s spouse are also taken into account.
As a result, the inherited shares are treated as part of a controlling interest and the taxable value is €90,000 not €55,000.
CAT is calculated on the higher valuation due to Section 27.
Contrast with Capital Gains Tax
To make it somewhat confusing, the CAT rules differ significantly from the position for CGT (Capital Gains Tax) under Section 548 TCA 1997.
For CGT purposes:
- minority discounts generally apply to the individual shareholding,
- there is no equivalent aggregation with relatives.
This distinction is important because advisers cannot assume that a valuation acceptable for CGT purposes will also apply for CAT.
Business Relief
Although Section 27 may increase the underlying valuation of inherited shares, Business Relief can still significantly reduce the CAT exposure.
The Section 27 valuation rules continue to apply before Business Relief is calculated but, where available, Business Relief reduces the taxable value of qualifying business assets by 90%.
Business Relief obviously has its own criteria and conditions so again, it’s important that this is discussed with a tax advisor.
Supporting the Family Following the Death of a Shareholder
A common question following the death of a shareholder is how the surviving shareholders or the company can provide immediate support to the deceased shareholder’s spouse or family, and how to do so tax efficiently.
Certain payments made on death may qualify for favourable income tax treatment under Section 201 TCA 1997. However, the rules are highly technical, and careful structuring is essential to ensure that the intended support for the family does not create unintended tax consequences for either the company or the family.
While the available reliefs can be generous, these arrangements must be properly structured, planned, and reported in order to achieve the intended tax treatment.
The Importance of Early Planning
The death of a shareholder can destabilise even well-run private companies if succession planning has not been addressed in advance.
The tax reliefs available can be extremely valuable, but they are also highly technical and easy to get wrong.
Proper planning in advance can make an enormous difference at an already difficult time.
