Family Investment Companies Vs Trusts:
Choosing the Right Structure for Long-Term Family Wealth
For families looking to hold and pass on substantial wealth across generations, the choice between a Family Investment Company and a trust shapes everything that follows. Here's how the two structures compare — and how to think about which fits.
For most of the twentieth century, the discretionary trust was the default structure for holding substantial family wealth. From the early 2000s – particularly after the 2006 reforms to the trust tax regime – a different structure has become increasingly common in advised cases: the Family Investment Company, or FIC.
A FIC is a private limited company set up to hold family wealth. Shares are held by family members (or trusts for their benefit), and the company holds investments — typically shares, property, or other appreciating assets. The structure looks corporate; its function is dynastic.
The choice between the two is not a choice between modern and old-fashioned. It is a choice between two genuinely different tools, each suited to different family circumstances.
How a FIC Actually Works
A FIC is a private limited company incorporated under standard UK company law, governed by its articles and a shareholders' agreement that can be tailored in detail. The family typically funds the company by way of loan – repayable over time, rather than being a chargeable transfer for IHT.
Shares can be structured in classes — voting, non-voting, income, growth — allowing founders to retain control while passing economic benefit to the next generation. Children and grandchildren receive growth shares that capture future appreciation outside the founders' estates, while the founders retain authority through voting shares and directorships.
Over time, as the loan is repaid and growth accumulates in the next generation's shares, wealth transfers gradually and tax-efficiently – without the front-loaded charges that affect lifetime transfers into discretionary trusts.
The Key Differences
Control
In a FIC, founders retain meaningful control through shareholding and directorships even after substantial value has passed to the next generation. In a trust, the settlor typically gives up control at settlement.
Tax Treatment
A FIC is taxed under corporation tax rules. A discretionary trust is taxed at trust rates on income and capital gains, with its own entry and periodic and exit IHT charges. For substantial wealth held over decades, the cumulative position can differ significantly.
Flexibility for Circumstance
The trustees' discretion to respond to unpredictable events is the trust's defining strength. The FIC distributes according to shareholdings, not discretion – it is more predictable and less responsive.
Privacy
A trust can be largely private. A FIC files public accounts at Companies House.
Administrative Burden
Both structures require serious ongoing administration. Neither is light. The right question is not "which requires less work" but "which produces a workload the family is best equipped to sustain."
Where Do Each Fit Better
FIC
Where founders want to retain control while passing economic benefit outwards. Where wealth is primarily investment-based and held long-term. Where the family is comfortable with corporate governance. Where the wealth involved justifies the running costs. The family gradually brings the next generation into the management of family wealth through shareholding and eventual directorship.
Trust
Where beneficiaries are vulnerable, young, or in unstable circumstances. Where flexibility to respond to unpredictable events matters. Where privacy is a priority. Where qualifying business or agricultural property is involved — particularly post-April 2026. Where the family's circumstances are likely to involve significant intra-family disagreement, and the trustees' independent judgment can hold the structure together.
Hybrid Structures
In many advised cases, the answer is not "FIC or trust" but "both". A FIC can be owned, in part, by a discretionary trust—combining corporate efficiency at the asset level with trust protection and flexibility at the shareholding level. These structures are more complex to design and administer and require advisers comfortable across company law, trust law, and tax. For families whose wealth justifies the complexity, the combined approach often produces outcomes neither tool achieves alone.
Where This Leaves Things
The wrong question is "which structure is best." The right question is "which structure best fits the family we actually are, the wealth we actually hold, and the future we actually intend to build." The answer earns its place when the analysis points to it. It loses its place when the structure is chosen for fashion, adviser preference, or imitation of what other families have done.
