With UK inheritance tax charged at 40% on estates above the £325,000 nil-rate band, wealthy families face a real challenge in passing on what they have built. The freeze on the nil-rate band, confirmed in the November 2025 Budget to run until April 2031, means more estates fall into the IHT net every year as property and investment values rise.

Older planning routes have lost some of their shine. Discretionary trusts attract an immediate 20% IHT charge on transfers above the nil-rate band and face 10-year anniversary charges of up to 6%. From April 2026, business property relief and agricultural property relief are also being capped, which narrows another popular route for shielding family wealth.

That is why the family investment company (FIC) has become one of the most talked-about structures in UK inheritance tax planning. A FIC lets the founders keep day-to-day control of family assets, move future growth into the next generation, and benefit from corporation tax rates rather than personal income tax rates on investment returns. This guide walks through how a FIC works, when it makes sense, and what to watch out for.

Key Takeaways

A family investment company is a UK private limited company set up to hold and grow family wealth. It is most commonly used by families with estates above £2 million who want a structured, tax-efficient way to pass assets to children and grandchildren without giving up control.

The mechanics are simple in principle. Parents fund the company, usually with cash or a director’s loan, and take voting shares. Non-voting shares are issued or later gifted to children. Those gifts are treated as potentially exempt transfers (PETs), which fall out of the donor’s estate completely if the donor survives seven years.

Profits inside the FIC are taxed at corporation tax rates. Most pure investment FICs pay the flat 25% main rate, though this is still often lower than the personal income tax rates the founders would otherwise pay on investment income. Most UK and overseas dividends received by a UK company are exempt from corporation tax, which avoids double taxation on portfolio income.

FICs avoid the upfront 20% lifetime IHT charge and the 10-year anniversary charges that apply to discretionary trusts. They also offer more flexibility on control and distribution. The trade-off is cost. Setup typically starts at around £5,000, with ongoing accountancy and legal fees, so FICs only really pay off for substantial estates.

What is a Family Investment Company

A family investment company is a private limited company incorporated under the Companies Act 2006, owned by family members, and used to hold investments such as cash, shares, bonds, and property. Unlike a trading company, its purpose is wealth management and intergenerational transfer rather than carrying on a business.

FICs gained ground after the 2006 trust changes brought immediate IHT charges on most lifetime transfers into trust. They sit somewhere between outright gifts and trust structures, offering corporate governance instead of trustee discretion.

A FIC can be set up as a private limited company, which files accounts at Companies House, or in some cases as an unlimited company, which avoids public filing of detailed accounts but loses the protection of limited liability. Most families choose the limited company route because the privacy benefit of an unlimited company rarely outweighs the personal exposure to debts.

The investment portfolio is the engine of the structure. A typical FIC holds a mix of cash, listed equities, fixed income securities, and sometimes commercial or buy-to-let property. The directors, usually the founders, manage the portfolio and decide when to declare dividends.

What makes a FIC different from an ordinary investment company is the deliberate share structure. Founders hold voting shares (often called A shares) that give them control over the board. Children and grandchildren hold non-voting shares (typically B and C shares) that carry rights to dividends and capital growth but no say in how the company is run.

How Family Investment Companies Work for IHT Planning

The IHT efficiency of a FIC comes from two things: structuring share classes carefully, and using the seven-year PET rule on share gifts.

The founders usually subscribe for voting A shares and put cash into the company, either as paid-up share capital or as an interest-free director’s loan. Cash funding is preferred because moving assets that have already grown in value into the company can trigger capital gains tax at the point of transfer. Director’s loans are popular because the founder can later draw the money back out of the company tax free as loan repayments, providing a clean source of retirement income.

Non-voting shares for the next generation can be issued at incorporation or gifted later. When parents gift these shares to adult children outright, the transfer is a PET. If the donor survives seven years from the date of the gift, the value of the gift drops out of their estate completely. Die within seven years and the gift becomes chargeable, although taper relief reduces the IHT due if death occurs between three and seven years after the gift. Note that gifts of shares into a discretionary trust do not qualify as PETs and may attract an immediate 20% IHT charge if they exceed the available nil-rate band, which is one reason direct gifting is the more common route.

This is where the structure earns its keep. Once the gifts are made, all future growth on the gifted shares belongs to the children, not the parents. The donor’s estate is effectively frozen at the value of the company at the time of the gifts, and decades of compounding returns sit safely outside the IHT net.

The different share classes also let directors target dividends. They can pay dividends only on certain share classes in a given year, which means income can be directed to the family member with the lowest marginal tax rate. A child at university, for example, may be able to receive dividends within their personal allowance and dividend allowance. Anti-avoidance rules such as the settlements legislation can apply where dividends are paid to a minor child of a settlor, so directing income to children under 18 needs careful advice.

Tax Benefits and Considerations

The tax case for a FIC rests on the gap between corporation tax rates and personal tax rates, plus the IHT savings on share gifts.

For the financial year starting 1 April 2026, corporation tax sits at 19% on profits up to £50,000, 25% on profits above £250,000, and at an effective marginal rate of 26.5% on the slice between those two thresholds. There is an important catch for FICs, however. Most pure investment FICs are classified as Close Investment Holding Companies (CIHCs) under section 18N CTA 2010, which means the small profits rate and marginal relief do not apply. A CIHC pays the full 25% main rate on all its profits, regardless of size. Property letting to unconnected third parties is a permitted purpose that takes a company out of CIHC status, but a FIC that just holds shares, bonds, or properties let to family members will normally be a CIHC.

Even at the flat 25% rate, the FIC can still beat personal ownership for a higher or additional rate taxpayer. A family member personally receiving £100,000 of investment income could pay 40% or 45% in income tax. The FIC pays 25% inside the company, and the family then has flexibility on when and how to draw the after-tax profits out.

Dividend income received by the FIC from UK and most overseas companies falls within the dividend exemption in Part 9A CTA 2009, so it is generally exempt from corporation tax. This avoids the double layer of tax that would otherwise apply on portfolio dividends. Withholding tax suffered on overseas dividends or interest can usually be credited against any UK corporation tax liability under double tax treaties.

Capital gains realised inside the FIC are taxed at corporation tax rates rather than personal CGT rates. For assets held since before 1 January 2018, indexation allowance can still be claimed for the period up to 31 December 2017, when the allowance was frozen. This can reduce the taxable gain on long-held shares or property significantly.

A FIC can also claim a corporation tax deduction for interest on loans used for the company’s investment business, which is not always available to individuals. This is one reason families sometimes prefer to fund a FIC with bank borrowing rather than equity for property purchases.

The director’s loan repayment route is one of the most attractive features for the founders themselves. Money lent to the FIC can be repaid in cash over many years without any further tax charge, providing a tax-free income stream alongside the IHT planning.

A FIC sits within the UK corporation tax regime, so good record keeping, accurate annual accounts, and timely CT600 filings are essential. Cutting corners here is the fastest way to undo the tax benefits of the structure.

Inheritance Tax Advantages

The IHT benefits of a FIC are immediate as well as long term. There is no upfront IHT charge when the company is incorporated and funded with cash, and no charge when shares are gifted directly to family, provided those gifts fall within the donor’s available reliefs and exemptions or qualify as PETs.

The PET mechanism is the heart of the strategy. Share gifts that survive the seven-year period become exempt from IHT, regardless of how much those shares have grown in the meantime. Even if the donor dies within seven years, taper relief reduces the IHT payable if death occurs between three and seven years after the gift, so the structure still offers some protection.

Unlike discretionary trusts, FICs do not face 10-year anniversary charges, which can take up to 6% of trust capital above the nil-rate band every decade. Avoiding these recurring charges can preserve hundreds of thousands of pounds for a substantial family over a generation.

Staged gifts of small share parcels each year let families use the £3,000 annual exemption per donor, the £250 small gift exemption, and the normal expenditure out of income exemption. Combined with the seven-year clock, this turns wealth transfer into a steady drip rather than a single chargeable event.

It is also important to avoid creating a gift with reservation of benefit. If the donor continues to derive a benefit from the gifted shares (for example, by receiving dividends on them or retaining rights that look economic rather than purely administrative), HMRC can treat the gift as still part of the donor’s estate, undoing the IHT benefit entirely.

Corporation Tax Treatment

Most pure investment FICs are CIHCs, so the headline corporation tax rate is the 25% main rate on all profits. This is the single most misunderstood aspect of FICs and one to flag with any adviser at the planning stage.

Rental income from property held inside the FIC is taxed at corporation tax rates. Mortgage interest is fully deductible at company level, unlike for individual buy-to-let landlords who only get a basic-rate tax credit. For higher rate taxpayers running a portfolio, this difference alone can justify a corporate structure.

Capital gains are taxed at corporation tax rates with the benefit of indexation allowance up to December 2017. For property and shares held for many years, this can make a meaningful difference to the effective tax rate on disposal.

The dividend allowance for individual shareholders has been £500 since 6 April 2024 (down from £1,000 in 2023/24 and £2,000 before that). From 6 April 2026, dividend tax rates also rose by 2 percentage points: 10.75% at the basic rate, 35.75% at the higher rate, and 39.35% at the additional rate (unchanged). With the allowance squeezed and rates higher, distribution planning across multiple shareholders matters more than ever.

Comparison with Discretionary Trusts

The FIC versus discretionary trust question is one of the bigger choices in modern UK estate planning. Both can move wealth out of an estate, but they work very differently.

Control is the clearest difference. The founders of a FIC can keep all the voting rights and run the board for as long as they wish. With a discretionary trust, settlors hand assets and decision-making to trustees, who must act in the beneficiaries’ interests rather than the settlor’s.

The upfront tax cost also differs. A FIC incurs no IHT entry charge on cash funding or on PET share gifts to individuals. A discretionary trust funded above the nil-rate band attracts an immediate 20% lifetime IHT charge on the excess.

Ongoing tax is another point of contrast. Discretionary trusts face 10-year anniversary charges of up to 6% on the value above the nil-rate band, plus exit charges when capital is paid out. FICs face no equivalent periodic IHT charges.

Distribution flexibility tips in favour of FICs because directors can declare dividends only on the share classes they choose, allowing income to flow to family members on lower marginal rates. Trusts can do similar planning, but only within the trustees’ fiduciary duties and the terms of the trust deed.

Privacy is one area where trusts come out ahead. A limited company FIC must file accounts at Companies House and disclose persons with significant control. Trusts are registered with HMRC under the Trust Registration Service but the contents are not publicly searchable in the same way.

Cost is the practical filter. FICs typically need professional setup and ongoing accounting, often running into several thousand pounds a year. For estates close to the nil-rate band, that overhead rarely makes sense.

When FICs Are Most Suitable

A FIC is not the right answer for every wealthy family. It works best in a narrow set of conditions.

Estate size is the first filter. As a rough guide, FICs become viable when the family wealth being planned around is comfortably over £2 million, excluding the main home. Below that level, the legal and accounting costs eat into the tax savings.

Control matters too. Founders who want to direct investment strategy, decide on dividends, and influence how the next generation is brought into the family wealth typically prefer the corporate route over a trust. FIC founders can sit as directors and hold voting shares for life.

Income-generating portfolios suit FICs particularly well. Buy-to-let portfolios, dividend-paying share portfolios, and other regular income streams benefit from corporation tax rates and from the ability to retain profits inside the company for further investment.

Long planning horizons help. The seven-year PET clock and the gradual accumulation of growth in the children’s shares mean the structure rewards families who think in decades, not months.

Family dynamics also matter. FICs work best where the next generation is engaged, where succession is reasonably clear, and where the founders are happy to bring children onto the share register early. Where relationships are fragile or succession is uncertain, the rigidity of a fixed share structure can be a drawback rather than an advantage.

Potential Drawbacks and Limitations

FICs are not without their costs and risks, and a clear-eyed view of these matters before committing.

Setup and running costs are the most obvious. A basic FIC typically costs from around £5,000 to set up properly, with bespoke share rights and shareholders’ agreements pushing the figure higher. Annual costs cover accounts, the corporation tax return, Companies House filings, and often legal advice on share transfers and dividends.

Double taxation can become an issue when profits leave the company. Corporation tax is paid inside the FIC, and shareholders then pay dividend tax when distributions are made. For many families this is fine because the founders rely on director’s loan repayments and the next generation receives modest dividends within their allowances, but it is not automatically more efficient than personal ownership.

Capital gains tax can be triggered on funding. Putting an existing share portfolio or buy-to-let property into a FIC counts as a disposal at market value, which can crystallise large gains. Cash funding avoids this, but for families who already hold significant assets personally, the CGT cost of moving them in can be substantial. Stamp duty and Stamp Duty Land Tax can also apply to in-specie transfers of shares or property.

Business property relief and agricultural property relief do not apply to FIC shares, because investment companies do not qualify. From April 2026, even direct holdings of qualifying business and agricultural property are restricted to 100% relief on the first £1 million combined, with 50% relief above that. The November 2025 Budget confirmed the £1 million allowance is transferable between spouses and civil partners, giving couples up to £2 million between them. Families with genuine trading businesses or farms need to weigh whether moving those assets into a FIC would forfeit valuable reliefs.

Annual Tax on Enveloped Dwellings (ATED) applies to UK residential property worth over £500,000 held inside a company, unless a relief applies (such as the let-to-third-parties relief). ATED charges run from a few thousand pounds a year for properties just over the threshold to over £200,000 for the most expensive homes. This usually rules out using a FIC to hold the family home.

Compliance is ongoing. Annual accounts, corporation tax returns, confirmation statements, the PSC register, and the Trust Registration Service if any shares are held in trust all need attention.

Flexibility is more limited than with a discretionary trust. Once shares are gifted, they belong to the recipient. If circumstances change, restructuring is possible but rarely simple.

Key Implementation Considerations

Getting the structure right at the outset is far cheaper than fixing it later.

Professional advice is essential. Corporation tax, capital gains tax, IHT, dividend tax, ATED, stamp duty, and the CIHC rules all interact. A specialist tax adviser working alongside a corporate solicitor is usually money well spent.

Share class design is the heart of the structure. The articles of association need to spell out voting rights, dividend rights, capital rights on a winding up, and transfer restrictions (often through a shareholders’ agreement and pre-emption rights). Poorly drafted articles can lock the family into an unhelpful position for years.

Timing of share gifts pays off. Spreading gifts across multiple tax years uses annual exemptions, keeps each gift’s seven-year clock independent, and reduces the impact of any one of those clocks failing.

Funding methodology has knock-on effects. Cash and director’s loans avoid CGT on entry but tie up liquidity. Asset transfers may suit families who hold assets with little embedded gain or who can use rollover or holdover reliefs.

Integration with the wider plan matters. Wills, lasting powers of attorney, pensions, and any existing trusts should all be reviewed at the same time so the FIC complements rather than conflicts with the rest of the estate plan.

Investment policy inside the FIC should be set deliberately. Asset allocation, risk tolerance, and any ESG or family values should be documented, with a clear understanding of how the corporate tax treatment of different income types affects after-tax returns.

Recent Developments and Future Outlook

The landscape around FICs continues to shift, and several recent changes are worth flagging.

The November 2025 Budget extended the freeze on the nil-rate band and residence nil-rate band to April 2031. With property and investment values continuing to rise, this means more families will be drawn into IHT planning each year, and structures like FICs will keep gaining attention.

From April 2026, business property relief and agricultural property relief are capped. Only the first £1 million of combined qualifying business and agricultural property attracts 100% relief, with 50% relief above that. The £1 million allowance is now transferable between spouses, giving married couples up to £2 million combined. This is a significant change for farming families and owners of family businesses, and it is one of the main drivers behind renewed interest in FICs as part of a wider wealth strategy.

From April 2027, most unused pension funds and death benefits are due to be brought into the IHT net for the first time. Pensions have traditionally been one of the cleanest IHT shelters, and that change alone is likely to push more families towards corporate and trust structures.

The corporation tax rate of 25% (with the 19% small profits rate where it applies) is set to remain unchanged in the financial year beginning 1 April 2026. The government has confirmed an intention to cap the main rate at 25% for the duration of the current Parliament.

Dividend tax rates rose from 6 April 2026. Basic rate dividend tax is now 10.75% (up from 8.75%), the higher rate is 35.75% (up from 33.75%), and the additional rate stays at 39.35%. The dividend allowance remains £500. Combined, these changes raise the cost of extracting profits from any company, which makes director’s loan repayments and timing of dividends across multiple family shareholders more important than before.

HMRC scrutiny of FICs has been steady rather than dramatic. A dedicated HMRC unit looking at FICs was disbanded in 2021 after concluding there was no evidence of widespread non-compliance, but ordinary compliance activity continues. Genuine commercial substance, properly drafted articles, accurate accounts, and arm’s-length dealings remain the best defence.

Looking forward, the safest assumption is that thresholds will keep being squeezed and reliefs trimmed. FICs that are built for flexibility, with clean documentation and a clear commercial rationale, are best placed to weather future changes.

FAQ

Q: What is the minimum estate size where a family investment company becomes worthwhile?

A: As a working rule, FICs become economic for families with planning wealth above £2 million, excluding the main home. Setup costs typically start around £5,000 and ongoing fees can run to several thousand pounds a year, so smaller estates are usually better served by simpler planning such as outright gifts, life policies, and use of the nil-rate bands.

Q: Can existing companies be converted into family investment companies?

A: Yes. Existing investment or trading companies can be re-papered as FICs with new articles, share classes, and a shareholders’ agreement. The reorganisation itself can have CGT and stamp duty implications, and care is needed if the company qualifies for business property relief that would be lost on a switch to investment activity.

Q: How long does it take to set up a family investment company?

A: Typically four to eight weeks, including drafting bespoke articles, incorporating at Companies House, opening bank accounts, and putting the funding in place. More complex structures with multiple share classes, asset transfers, or a trust layer can take longer.

Q: Can family investment company shares be held in trust?

A: Yes. Shares for minor children, vulnerable beneficiaries, or future generations are often held in a trust to combine the FIC’s control benefits with the protection a trust offers. The trust will have its own tax profile and reporting obligations, and a transfer of shares into a trust above the available nil-rate band can attract an immediate 20% IHT charge, so the layered structure needs careful design.

Q: What happens if the donor dies within seven years of gifting shares?

A: The PET fails and becomes chargeable. The gift’s value at the date it was made is added back into the donor’s estate for IHT purposes. Taper relief can reduce the tax on gifts made between three and seven years before death, but it only reduces the tax on the gift itself, not on the rest of the estate.

Q: Are there any restrictions on what investments a family investment company can hold?

A: A FIC can hold most investments, including cash, listed shares, bonds, collective investments, and property. UK residential property over £500,000 brings ATED into play unless a relief applies, which usually rules out holding the family home. Most pure investment FICs are CIHCs, which means the 25% main rate of corporation tax applies on all profits, with no access to the small profits rate.

The family investment company has earned its place as one of the most useful tools in UK inheritance tax planning. For families with the wealth to justify the cost, a properly designed FIC offers a rare combination of control, tax efficiency, and a clear path for transferring wealth to the next generation. The structure is not a shortcut, and the benefits depend on careful design and disciplined ongoing management, but for the right family it remains one of the strongest options available under current UK law.
