Family Investment Companies (FICs) are no longer a “niche planning idea”.

In the UK, they have matured into a mainstream, highly flexible structure for intergenerational wealth planning — and, in our experience, they are increasingly being considered as a core pillar of estate planning for families with significant investable assets.

This article provides an institutional overview of why FICs have become so prominent, what typically drives their adoption, and where the real technical and practical pressure points sit (especially when clients want to use existing assets or restructure an existing investment company).

Why FICs have become the estate planner’s “modern weapon of choice"

Two forces have pushed FICs firmly into the mainstream.

First, the long-term impact of the post-2006 trust tax environment.

The inheritance tax (IHT) profile of discretionary trusts (entry charges in certain cases, periodic charges, and exit charges) has made many trust-based solutions less attractive for larger wealth transfers, particularly when weighed against a FIC’s ability to support long-term compounding with governance control retained by the founder.

Second, increasing market confidence following HMRC’s risk review focus. HMRC’s dedicated FIC unit (created in 2019) was later disbanded, with HMRC indicating it found no evidence that FICs were correlated with non-compliance and that FICs would be treated as “business as usual”. This matters because it signals that the structure itself is not inherently suspect — although, of course, any individual implementation still needs to be robust and correctly documented.

What a Family Investment Company actually is.

A “FIC” is not a special legal regime. It is typically a private company limited by shares, designed with tailored share classes and governance to separate (i) control and (ii) economic benefit across generations.

In practice, founders commonly retain voting/control shares (often with limited economic rights), while children and/or grandchildren hold non-voting shares that carry the economic participation. The design intent is to support long-term wealth transfer while preserving a clear governance structure and family safeguards.

The tax and economic logic: corporation tax, dividends, compounding (and the “double tax” reality)

The attraction of a corporate wrapper is often driven by (a) the corporation tax environment on investment profits and (b) the ability to retain returns inside the company to compound over time, rather than suffering personal tax drag annually. The dividend position can be particularly relevant for equity-heavy portfolios.

That said, any institutional overview must be honest about the “double layer” issue: company profits may be taxed in the company, and then taxed again when extracted by shareholders (typically via dividends). This is why FICs are frequently most effective as long-horizon structures where value is retained and compounded, and where founder loans (where appropriate) can provide a tax-efficient method of drawing capital back over time.

Funding a FIC with existing assets: where plans succeed (and where friction appears)One of the most common questions we receive is: “Can I build a FIC using assets I already own?”

Sometimes, yes — but the answer is rarely “just transfer everything in”. Transferring existing investments into a company can crystallise capital gains tax (CGT) on a market value disposal. For property, the position can be more complex again, with stamp duty land tax (SDLT) potentially in play (and additional regimes potentially relevant depending on facts).

This is precisely where modelling and sequencing matter. In many cases, funding via cash/director’s loan is the cleanest starting point, while any transfer of existing appreciated assets requires careful cost/benefit analysis against the long-term IHT and compounding objectives.

Converting an existing investment company into a FICA significant number of families already hold investments through corporate vehicles (often formed for property or investment administration reasons). In some cases, it can be more efficient to restructure the existing company into a FIC-style governance and share-class framework than to create a brand-new vehicle and “move” assets across.

However, share reclassifications, bespoke articles, shareholder agreements, and the tax analysis around any reorganisation must be managed carefully. This is not an area where “template” structures are appropriate.

A critical caution: share valuations and the “growth share” trap.

FICs can be extremely effective — but they must be correctly valued and properly implemented. A recurring risk area is the temptation to treat certain share classes (for example, shares with restricted current rights but exposure to future growth) as having “nil” value. HMRC’s valuation approach is market-based, and undervaluations can create serious exposure (including extended enquiry windows if relevant returns are not correctly made).

Professional valuation and specialist advice are not optional add-ons in this space; they are core risk controls.
