What is a discretionary trust?
A discretionary trust is a flexible legal arrangement where assets such as property, cash, or investments are placed under the control of appointed trustees. The trustees hold and manage these assets for a specified group of potential beneficiaries.
Unlike fixed trusts, no individual beneficiary has an absolute legal right to the trust’s income or capital. Instead, the defining feature of a discretionary trust is that the trustees retain total discretion over how, when, and to whom distributions are made. While the settlor names the class of potential beneficiaries, the ultimate decision-making power rests entirely with the trustees. Settlors often accompany the trust deed with a non-binding ‘letter of wishes’ to guide the trustees’ choices.
What is a letter of wishes?
A letter of wishes is a confidential, non-legally binding document which accompanies a will or a trust. While a will sets out the formal legal instructions for how your estate should be distributed, a letter of wishes provides your trustees with detailed guidance on how you would like them to exercise their discretion and carry out your intentions.
Although it does not alter or override the legal terms of a will or trust deed, it allows you to express your reasoning and personal preferences.
Key roles in a discretionary trust
Setting up a discretionary trust involves three core roles: the settlor, the trustees, and the beneficiaries. Each party plays a distinct legal role in how the trust is established, managed, and distributed:
- Settlor: The individual who creates the trust and transfers assets into it.
- Trustees: The legal owners responsible for holding and managing the trust assets.
- Beneficiaries: The individuals, group of people, or entities designated to benefit from the trust assets.
Can a discretionary trust have only one beneficiary?
No. For a discretionary trust to function legitimately under UK law, there must be a pool or ‘class’ of multiple potential beneficiaries (e.g., naming other children, grandchildren, extended family, or charities alongside a primary disabled beneficiary).
This gives trustees a genuine selection over whom to distribute to, satisfying the requirement for trustee discretion. You can then use your letter of wishes to ask the trustees to prioritise the needs of your primary beneficiary.
How does a discretionary trust work?
A discretionary trust can be created during your lifetime (Lifetime Discretionary Trust) or written into your will to take effect upon death (Discretionary Will Trust). The structure operates through a sequence of defined legal steps:
- The settlor creates the trust: The settlor transfers assets into the trust structure during their lifetime or via instructions in their will.
- Trustees manage the estate: Trustees assume legal ownership and are bound by fiduciary duties to manage and invest the trust assets in the best interests of the beneficiaries.
- Trustees exercise discretion (guided by a letter of wishes): The trustees decide which beneficiaries receive payouts, how much they receive, and when distributions occur. While they retain ultimate legal control, they refer back to the settlor’s letter of wishes to align their choices with the settlor’s original intentions.

What are the benefits of a discretionary trust?
A discretionary trust offers an unmatched degree of flexibility and asset protection, making it one of the most effective structures in estate planning & asset distribution. By utilising this legal structure, settlors can safeguard assets for future generations while remaining adaptable to unpredictable family developments.
- Adaptable to changing circumstances: Gives trustees full discretion over when and how much income or capital to distribute, allowing them to adapt to beneficiaries’ changing needs or financial circumstances.
- Protecting vulnerable beneficiaries: Ideal for safeguarding family members who may be unable to manage large sums independently, such as those with learning difficulties, health conditions, addiction issues, or young and inexperienced relatives.
- Protecting means-tested benefits: As trust assets are not legally owned by any single beneficiary, funds held in a discretionary trust generally don’t affect a disabled or vulnerable beneficiary’s entitlement to means-tested state benefits or local authority care funding. It also shields vulnerable relatives from the risk of financial exploitation by third parties.
- Asset protection from third-party claims: Assets are generally shielded from claims arising from divorce, financial hardship, or bankruptcy.
- Preserving family wealth across generations: Allows settlors to pass capital safely to grandchildren or future generations, keeping family wealth protected within the structure rather than risking direct loss.
- Effective tax planning: Using structures like a nil-rate band discretionary trust can help reduce your inheritance tax bill while keeping your wealth fully protected.
What are the disadvantages of a discretionary trust?
Although establishing a discretionary trust provides robust asset preservation and adaptable wealth management, it also involves statutory duties, continuous administrative oversight, and taxation considerations that require detailed evaluation.
- Loss of direct control over assets: Settlors must hand over absolute ownership and management of assets to the designated trustees. You rely entirely on the trustees to exercise their discretion appropriately and in accordance with your letter of wishes.
- Administrative burden and trustee responsibilities: Running a discretionary trust involves ongoing statutory duties, including maintaining accurate trust accounts and completing annual tax returns.
- Higher ongoing tax rates: Income retained within a discretionary trust is subject to the trust rate of tax, such as 45% for additional rate income and 39.35% for dividend income.
- Potential for beneficiary disputes: Asset distributions can occasionally cause family friction or disagreements among beneficiaries.

What are the discretionary trust tax implications?
Discretionary trusts offer trustees complete discretion over how income and capital are allocated; HMRC subjects them to a distinct tax regime. In most circumstances, discretionary trusts fall under the relevant property regime for inheritance tax and attract the highest marginal rates for income tax and capital gains tax.
Discretionary trust inheritance tax
Discretionary trusts are governed by the relevant property regime, triggering IHT liabilities at three key points:
- Entry charges: Lifetime transfers above the settlor’s Nil Rate Band (£325,000) incur an immediate 20% charge.
- 10th anniversary charges: Net asset values exceeding the Nil Rate Band are taxed at up to 6% every ten years.
- Exit charges: Distributing capital to beneficiaries between 10-year anniversaries incurs a proportional charge capped at 6%.
Discretionary trust income tax
Trustees are responsible for paying income tax on income generated by trust assets (such as rent or dividends):
- Trust rates: Total trust income over £500 is taxed at the top rates: 39.35% for dividends and 45% for non-dividend income.
- Distributions: Distributed income carries a 45% tax credit, allowing lower-rate beneficiaries to reclaim tax from HMRC.
Discretionary trust capital gains tax
This applies when trustees sell, transfer, or dispose of trust assets that have increased in value:
- CGT rates: Chargeable gains above the allowance are taxed at 24%.
- Exempt allowance: Trustees receive half of an individual’s annual tax-free exemption.
- Holdover relief: CGT can be deferred on transfers into or out of the trust using Section 260 TCGA 1992 relief.
While discretionary trusts involve administrative tax duties, strategic planning such as utilising Nil Rate Bands can significantly reduce the overall tax burden. For expert legal advice, contact our specialist wills and probate solicitors.

Discretionary trust FAQs
What is a nil rate band discretionary trust?
A nil rate band discretionary trust is a tax-planning arrangement most commonly set up in a person’s will or established during their lifetime. It directs an amount up to the tax-free threshold (currently £325,000) into a trust, rather than passing it directly to family members. The trustees can then manage and distribute these funds for selected beneficiaries, such as a spouse, children, or grandchildren.
Since the introduction of the transferable nil rate band in 2007, the primary purpose of a nil rate band discretionary trust has shifted from pure tax avoidance to asset protection and long-term estate management.
A nil rate band discretionary trust can be set up in two ways:
- Discretionary will trust: Takes effect on death, redirecting up to £325,000 into the trust to protect assets against risks like remarriage, sideways disinheritance, or care costs.
- Lifetime discretionary trust: Established while the settlor is alive. Qualifying as a Chargeable Lifetime Transfer (CLT), funding up to £325,000 avoids an immediate 20% lifetime inheritance tax charge, provided the settlor survives seven years from the transfer date to fall outside their estate.
Are discretionary trusts tax efficient?
While discretionary trusts were heavily used for tax mitigation in the past, changes to inheritance tax rules, such as the transferable spouse allowance, and higher trust tax rates mean they are no longer primarily tax-reduction tools. Today, their main value lies in asset protection, flexibility, and safeguarding funds for specific family members.
Can a discretionary trust be dissolved?
Yes, a discretionary trust can be dissolved, a process legally referred to as winding up or terminating the trust. Under UK trust law, dissolution typically occurs when the trustees exercise their legal powers of appointment to distribute all remaining trust capital and income to the beneficiaries.
Should I set up a discretionary trust in my will or during my lifetime?
A lifetime trust takes effect immediately, making it ideal for early succession planning, asset protection, or supporting a relative right away. A discretionary will trust takes effect only after your death, which works well for distributing an estate among complex or blended families.
Can a beneficiary also serve as a trustee?
Yes, a beneficiary can legally act as a trustee. However, appointing at least one independent, non-beneficiary trustee is strongly recommended to maintain objective decision-making and avoid potential conflicts of interest over payouts.
Can I place residential property into a discretionary trust?
Yes, property can be placed in trust. Trustees can also permit a beneficiary to live in the home under a “right to occupy” arrangement, keeping the property secure without transferring direct legal ownership to the occupant.
What legal rights do beneficiaries have?
Beneficiaries do not have an automatic right to receive trust income or capital. Their only legal right is to be properly considered by the trustees whenever distributions are evaluated.
How long can a discretionary trust remain open?
Under the Perpetuities and Accumulations Act 2009, discretionary trusts established in the UK can run for up to 125 years. Trustees can also choose to close or wind up the trust earlier if all assets are distributed.
What happens if a trustee dies or steps down?
Trust deeds contain formal provisions for replacing trustees due to resignation, incapacity, or death, allowing remaining trustees or settlors to appoint replacements and ensure seamless continuity.
Can trustees decide to exclude a beneficiary?
Yes. Provided trustees act in good faith and follow the directions set out in the trust deed, they hold the legal authority to withhold distributions or exclude specific potential beneficiaries from a payout.
