Who this is for: For founders with significant retained profits or investment assets who are weighing up how to hold and govern family wealth.
A family investment company (FIC) and a discretionary trust are both used to hold wealth outside the founder's personal estate. They are not interchangeable. They solve different problems and create different obligations.
The family investment company
A FIC is a private limited company, typically with multiple share classes, designed to hold investments and accumulate wealth. The founder typically holds voting shares (retaining control) while other family members hold the new share class (receiving the benefit of future appreciation).
The advantages of a FIC are control, flexibility, and corporate tax rates on investment returns. The founder can retain full voting control while transferring economic value to the next generation. Investment returns are taxed at 25% corporation tax rather than 45% income tax or 20% CGT.
The disadvantage is that a FIC does not automatically remove value from the founder's estate for IHT purposes. If the founder holds voting shares that have economic value, those shares form part of their estate.
The discretionary trust
A discretionary trust removes assets from the founder's estate immediately on transfer, subject to the seven-year rule for IHT. The trustees (which can include the founder) have discretion over how the trust assets are distributed to the beneficiaries.
The advantages of a trust are IHT efficiency and asset protection. Assets held in trust are outside the founder's estate. They are protected from personal creditors and from divorce proceedings.
The disadvantage is that a trust is subject to the relevant property regime, which imposes a 10-year anniversary charge of up to 6% on the value of the trust assets, and an exit charge when assets leave the trust. For large trusts, these charges can be significant.
The structure that uses both
A SAFO typically combines a FIC and a trust. The FIC holds the trading company shares and investment assets, providing control and corporate tax rates. The trust holds the shares in the FIC, removing the economic value from the founder's estate.
The founder retains control through their role as director of the FIC and trustee of the trust. The economic value passes to the next generation through the trust structure.
The question is not which structure is better. It is which problem you are solving and which structure solves it.
| FIC | Discretionary Trust | SAFO (combined) | |
|---|---|---|---|
| IHT efficiency | Limited | High | High |
| Founder control | Full | Discretionary | Full |
| Tax on investment returns | 25% CT | 45% income / 20% CGT | 25% CT |
| Asset protection | Limited | High | High |

Both Are Growth-Layer Tools
A family investment company and a trust are both Growth-layer tools. The comparison between them is a legitimate question. It is also a question that assumes the choice between them is the most important decision.
The Expansion layer is the constitutional architecture that governs how either structure functions across generations, the governance framework, the decision-making structure, and the succession plan that determines how the family functions as a capital-owning unit rather than just as a collection of beneficiaries or shareholders.
The choice between a FIC and a trust is a Growth-layer decision. The constitutional architecture above it is the Expansion-layer decision. Most families make the first decision. The ones who retain the most capital across generations make both.
