Family Investment Companies for Property Portfolios: What They Actually Shield From IHT

Family investment companies get talked about as a neat alternative to trusts, and for the right portfolio they are — but "put it in a FIC and the Inheritance Tax problem goes away" is not how they actually work. A FIC does not remove a portfolio's existing value from your estate on day one. What it does is redirect where future growth lands, and give parents a company-law route to keep control while the next generation builds up value they never technically owned in the first place. Understood on those terms, it is one of the more useful structures available to landlords with portfolios that have real headroom left to grow.

What a family investment company actually is

Strip away the planning label and a FIC is an ordinary UK limited company, subject to the same Companies House and Corporation Tax rules as any other. What makes it a "family investment company" is the way the share capital and governance are built: rather than one class of ordinary shares, a FIC typically has several classes — often called alphabet shares (A, B, C and so on) — with different rights attached to each. Parents, or a trust they control, usually hold voting shares that carry control over the company but limited or no entitlement to future capital growth. Children, grandchildren, or a trust for their benefit, hold non-voting growth shares that carry little immediate value but stand to receive the increase in the company's worth over time.

The company then holds and manages the family's property portfolio in the normal way — collecting rent, paying expenses, funding new acquisitions, and selling properties as the strategy requires — just as any property investment company would, covered in more detail in our guide to buying property through a limited company.

How the IHT mechanics actually work

This is the part that gets glossed over. A FIC does not, by itself, take existing wealth out of your estate. If you sell your personally-owned portfolio to a FIC, or transfer it in, the value of what you receive back — shares, or a director's loan account — is still yours and still inside your estate. There is no shortcut around that.

What a FIC changes is what happens next. Because the growth shares are held by the next generation from the point the company starts trading, any increase in the portfolio's value from that point forward builds up in shares the parents never owned, rather than in an asset sitting in the parents' estate waiting to be taxed on death. Over a portfolio's working life, that future growth can be substantial — often larger than the value locked in at the point the structure was set up — which is where the real IHT benefit sits.

Existing value can be moved out over time too, through two main routes:

• Gifting voting or growth shares to the next generation, which is a potentially exempt transfer — falling out of the estate entirely if you survive seven years, on the same taper basis as any other lifetime gift.
• Repaying director loans. Where parents funded the company by lending it money rather than subscribing for shares, the company can repay that loan over time, moving cash back into the parents' hands (and, if it isn't spent, back into their estate — so this route needs pairing with spending or further gifting to actually reduce IHT exposure).

FIC vs trust: the comparison that actually matters

Trusts and FICs get compared constantly, and the honest answer is that they solve overlapping but not identical problems.

• Trusts offer more flexibility about who ultimately benefits and by how much, decided by trustees potentially years after the trust is set up. Against that, a relevant property trust carries its own IHT regime: an immediate charge where the transfer into trust exceeds the settlor's available nil-rate band, plus a periodic charge roughly every ten years and exit charges when capital leaves the trust — both capped at a maximum effective rate, but a real, recurring cost a FIC simply does not have.
• FICs have no periodic charge. In exchange, "who owns what" is fixed by the share structure at the outset, and while share classes and rights can be varied later, doing so is a formal company law exercise, not a trustee decision made quietly. What a FIC does offer that a trust doesn't is a familiar, transparent governance framework — voting shares, a board, statutory accounts — that many families and their advisers find easier to run day to day than a trust.
• The two are not mutually exclusive. A common structure has a discretionary trust holding the growth shares in a FIC, combining the FIC's absence of a periodic charge on the company itself with the trust's flexibility over which family members ultimately benefit and when.

The Corporation Tax trade-off

A FIC pays Corporation Tax on rental profits and on any gain when a property is sold, at the standard company rates — 19% up to £50,000 of profit, 25% above £250,000, with marginal relief tapering between the two. For a portfolio owner paying higher or additional rate income tax personally, and facing Section 24's restriction on mortgage interest relief covered in our guide to Section 24, the company rate is often meaningfully lower on income left inside the structure.

The trade-off is extraction. Profits taken out of a FIC as dividends or salary are taxed again on the recipient, and the same profit-extraction question that applies to any property company — covered in our guide to extracting profit from a property company — applies equally here. A FIC works best as a long-term holding vehicle for wealth that doesn't need to be drawn out regularly, not as a substitute for a portfolio that's meant to fund current living costs.

Where FICs fall short

They are not a fit for every portfolio:

• No Business Property Relief. A property letting business is, for IHT purposes, treated as "wholly or mainly" an investment activity, not a trading one, whether it's held personally or through a FIC. That means a FIC holding buy-to-let property does not attract Business Property Relief simply by virtue of being a company — the same restriction that applies to the personal ownership route covered in our guide to Inheritance Tax planning for landlords.
• ATED exposure. If a FIC owns UK residential property worth over £500,000 and it isn't let out on a genuinely commercial basis to an unconnected tenant, the Annual Tax on Enveloped Dwellings can apply — see our guide to ATED for how that charge works and the reliefs available for bona fide letting businesses.
• Set-up and running costs. Getting the share structure, articles of association and shareholders' agreement right needs proper legal and tax input, and the company then carries ongoing accounting, filing and governance costs that a personally-held portfolio doesn't. For a modest portfolio with limited growth prospects, those costs can outweigh the IHT benefit.
• Loss of control if shares are gifted outright. Gifting growth shares directly to adult children means they own them outright, with all the usual risks — divorce, creditors, or simply a change of mind about how the money should be used — that direct gifts always carry. This is usually managed with carefully drafted articles and, often, a trust holding the growth shares rather than individuals.

Who a FIC actually suits

The clearest fit is a portfolio landlord or developer with substantial existing wealth, a portfolio expected to keep growing significantly, and family members they want to benefit from that future growth without handing over full control today. It is far less compelling for a portfolio near the end of its growth phase, for owners who need to draw most of the rental income as personal spending, or for anyone unwilling to take on the legal and accounting cost of running a proper company structure. As with incorporation more generally — see our guide to incorporation relief for landlords — the right answer depends heavily on the specific portfolio, not a general rule of thumb.

Common questions

What is a family investment company?

An ordinary UK limited company, usually with more than one class of share, set up to hold and grow family wealth such as a property portfolio. Parents typically retain voting shares and control, while children or a family trust hold non-voting growth shares, so future increases in value accrue outside the parents' estate from the outset.

How does a family investment company reduce Inheritance Tax?

It does not remove existing wealth from your estate immediately. It redirects future growth into shares the next generation has held from the start, so increases in the portfolio's value after that point sit outside the parents' estate. Existing value can also be moved out over time by gifting shares or repaying director loans.

Does a family investment company pay Corporation Tax on rental income?

Yes, at standard company rates on both rental profits and gains on sale, rather than an individual's income tax and CGT rates. This is often lower for higher-rate taxpayers, but profits taken out as dividends or salary are taxed again on the recipient.

What's the difference between a family investment company and a trust for IHT planning?

A discretionary trust carries its own IHT regime, including periodic charges roughly every ten years, in exchange for more flexibility over who ultimately benefits. A FIC has no periodic charge but fixes ownership through its share structure at the outset, with changes handled as a formal company law exercise.
