Making trust planning tax-efficient for families 

As family structures and asset portfolios become more complex, estate planning increasingly involves more than the straightforward transfer of wealth. In some circumstances, introducing structure around how assets are held and distributed is just as important as reducing tax exposure. Trust planning provides one such framework. 

Trusts are long-established legal arrangements that allow assets to be managed on behalf of chosen beneficiaries. They can introduce flexibility, protection and oversight, and in appropriate cases, play a meaningful role in managing inheritance tax exposure. They are not a universal solution and do bring ongoing responsibilities. When properly structured, however, they can form an integral part of a considered long-term plan. 

What a trust does in practical terms 

A trust separates legal ownership from benefit. 

When assets are placed into trust, trustees become the legal owners and are responsible for managing those assets in accordance with the terms of the trust deed. The beneficiaries are the individuals who may benefit from the trust, either by receiving income, capital or both. 

This distinction allows the person creating the trust, known as the settlor, to introduce structure around how and when wealth is accessed. Instead of transferring assets outright, the settlor defines the framework within which trustees make decisions. 

Trusts can be created during lifetime or under a Will to take effect on death. The objectives and tax consequences may differ depending on which route is chosen. 

Why families consider trusts 

Tax is often part of the conversation, but it is seldom the only factor. 

Trusts are commonly used where: 

• Beneficiaries are young. 
• A beneficiary may be financially inexperienced or vulnerable. 
• There is concern about future divorce or creditor claims. 
• A second marriage creates competing interests between a surviving spouse and children from a previous relationship. 
• The family wishes to retain flexibility rather than fixing entitlements in advance. 

For example, a discretionary trust gives trustees the ability to decide which beneficiaries receive funds and when. This flexibility can be valuable where circumstances are likely to change over time, or where equal division would not be appropriate at every stage. 

A life interest trust, by contrast, might allow a surviving spouse to receive income from assets during their lifetime, while preserving the underlying capital for children. This structure can provide security for one generation while safeguarding inheritance expectations for the next. 

Other arrangements, such as bare trusts, operate differently. In a bare trust, the beneficiary has an immediate and absolute entitlement to the assets, even if they are held by trustees until a particular age. In substance, this is closer to an outright gift, but with administrative oversight. 

The choice of trust determines both the level of control retained and the tax treatment that applies. 

How inheritance tax applies to trusts 

When assets are placed into most types of lifetime trust, the transfer is measured against the individual’s available inheritance tax allowance, commonly referred to as the nil rate band. This allowance is currently £325,000 per person. It represents the amount that can be transferred, either during lifetime or on death, before inheritance tax becomes payable. 

If the value of assets transferred into trust exceeds the available nil rate band, an immediate inheritance tax charge may arise on the excess, typically at a rate of 20 per cent. Where the value transferred falls within the available allowance, there may be no upfront tax charge. However, that does not mean the trust falls outside the inheritance tax regime altogether. 

Many lifetime trusts fall within what is known as the relevant property regime. Under this framework, inheritance tax is assessed at intervals rather than only on death. Broadly, a charge can arise on each ten-year anniversary of the trust’s creation, calculated by reference to the value of the trust fund at that time. Additional charges may apply when capital is distributed to beneficiaries between those ten-year anniversaries. 

The rate of these periodic and exit charges is lower than the 40 per cent rate that applies to estates on death, and in many cases the effective rate is significantly lower. Nevertheless, they form part of the long-term cost of using a trust and should be factored into planning from the outset. 

Trusts established under a Will operate differently. Assets passing into certain types of trust on death may use the deceased’s available nil rate band and, in some cases, benefit from spousal exemption if structured appropriately. The interaction between Will trusts and inheritance tax allowances can be particularly relevant in second marriage situations or where asset protection is a priority. 

It is also important to consider the gift with reservation rules. If an individual places assets into trust but continues to benefit from them, for example by living in a property without paying full market rent, those assets may remain within their estate for inheritance tax purposes despite the transfer. The effectiveness of trust planning therefore depends on genuine separation of benefit. 

Trust planning can help manage inheritance tax exposure by removing assets, and future growth on those assets, from the settlor’s estate. However, the tax outcome depends on the structure chosen, the value transferred and the settlor’s wider estate planning position. It should always be approached as part of a coordinated strategy. 

Ongoing responsibilities and compliance 

Establishing a trust creates a continuing legal relationship. It is not simply a document that sits alongside a Will or lifetime plan. 

Trustees assume fiduciary duties. They must act in the best interests of the beneficiaries, exercise independent judgement and avoid conflicts of interest. Where investments are involved, trustees are required to consider suitability and diversification. This often involves taking appropriate professional advice and reviewing investment performance periodically. 

Administrative responsibilities are equally important. Most express trusts must be registered with HMRC’s Trust Registration Service, and details must be kept up to date. Trustees may be required to file annual tax returns if the trust receives income or realises capital gains. Income tax and capital gains tax may be payable at rates that differ from personal rates, and distributions to beneficiaries may carry tax consequences that need to be understood. 

From an inheritance tax perspective, accurate record-keeping is not optional. The value of assets at the time they are transferred into trust must be recorded carefully, as this forms the baseline for calculating future ten-year charges. Trustees should retain documentation of valuations, distributions and significant decisions throughout the life of the trust. When ten-year anniversaries arise, the trust fund must be valued and any inheritance tax charge calculated and reported. 

Where records are incomplete or administration has been informal, trustees may face difficulty reconstructing historic values or justifying tax calculations. This can lead to delay, additional professional costs and potential exposure to interest or penalties. 

For these reasons, the choice of trustee should be made with care. Some families appoint trusted relatives. Others involve a professional trustee to provide continuity, regulatory oversight and impartial decision-making. In many cases, a combination of family and professional trustees offers balance. 

Trust planning offers flexibility and protection, but it carries responsibility. Understanding that balance at the outset helps ensure the trust operates as intended over the long term. 

A structured and considered strategy 

Trusts remain an established and legitimate part of inheritance tax planning. Used well, they introduce governance, protection and flexibility, and in appropriate cases help manage long-term tax exposure while bringing clarity to intergenerational wealth planning. 

That value depends on careful design and ongoing oversight. The tax framework is deliberate. The reporting obligations are real. And the importance of thorough, consistent record-keeping cannot be overstated. When incorporated into a broader estate planning strategy and maintained with proper review and documentation, trusts can provide stability, protection and long-term reassurance for families navigating complex financial and personal considerations.
