Discretionary Trusts Explained
A UK Guide to Flexible Trust Planning
What is a Discretionary Trust?
A discretionary trust is a flexible legal arrangement in which trustees hold assets for a group of people — the beneficiaries. What sets it apart from other trusts is that no single beneficiary has a fixed right to the income or capital. Instead, the trustees have the discretion to decide who benefits, how much they receive, and when. That flexibility is what makes the discretionary trust one of the most widely used structures in UK estate planning.
FAQs: Discretionary Trusts
How a Discretionary Trust Works in Practice
Like all trusts, it rests on three roles, set out in a legal document called the trust deed:
-
The Settlor — the person who provides the assets (money, property or shares) to establish the trust.
-
The Trustees — the legal owners responsible for managing the assets. They must act in the beneficiaries' best interests and are guided by the settlor's letter of wishes.
-
The Beneficiaries — a defined "class" of people (for example, "my children and grandchildren") who may benefit at the trustees' discretion.
The letter of wishes is an important feature: it isn't legally binding, but it tells the trustees how the settlor would like them to exercise their discretion, providing guidance without locking the trust into rigid terms.
Five Reasons Families Use Dicretionary Trusts
Flexibility is the headline benefit, but most families set one up for specific protection or planning reasons:
-
Protecting Vulnerable Beneficiaries: This arrangement is ideal for situations where a family member may not be able to manage a large sum directly due to age, disability, or personal circumstances, as the trustees control how and when the funds are released.
-
Asset Protection From Third Parties: Because no beneficiary has a fixed entitlement, the trust fund is generally better protected from claims arising in a beneficiary's divorce or bankruptcy.
-
Inheritance Tax Planning: Moving assets into trust can reduce the value of your taxable estate over time, though the trust itself falls within the "relevant property" regime and may face periodic charges (see below).
-
Generational Wealth Planning: You can provide for several generations without the assets being spent all at once by a single heir.
-
Continuing Influence After Death: A discretionary trust lets you shape how your wealth is used long after you're gone – supporting specific goals such as education or first-home deposits.
A Note On Tax
Discretionary trusts sit within the relevant property regime, which means they can be subject to their own inheritance tax charges: typically a charge on each ten-year anniversary and "exit charges" when capital leaves the trust. They also have their own income tax and capital gains tax treatment. These charges are manageable and often modest relative to the protection a trust provides, but they're a key reason discretionary trusts should be set up and reviewed with professional advice. Tax treatment depends on circumstances and may change.
The Trustees' Administrative Duties
Running a trust is a genuine legal responsibility. Trustees must, among other things:
-
Register the Trust: Most UK trusts must be registered with HMRC's Trust Registration Service (TRS).
-
Meet Regularly: Trustees should meet at least annually to review the trust's objectives and the beneficiaries' changing needs.
-
Keep Accurate Records: This includes formal minutes of decisions and detailed financial accounts for tax purposes.
Because these duties are ongoing and the consequences of getting them wrong can be significant, many trustees choose to appoint a professional adviser to support them — which is where we can help.
Understanding the Trust Registration Service (TRS)
The TRS is HMRC's online register of trusts, introduced under anti-money-laundering rules. Trustees must gather specific information and meet strict deadlines. The following is a practical overview — not a substitute for advice on your particular trust.
Getting Set Up
Before registering, trustees should nominate a lead trustee as the main point of contact with HMRC (though all trustees remain equally responsible in law). You'll need the trust deed and any letter of wishes to hand to confirm the trust's exact name and creation date, and you'll need to classify the trust as either taxable (liable to IHT, CGT, income tax or SDLT) or non-taxable (an express trust with no current UK tax liability).
The Information Required
HMRC requires detailed information on the trust's "beneficial owners" — settlors, trustees and beneficiaries — typically including full names and dates of birth, National Insurance numbers for UK residents (or passport and address details for non-residents), and nationality and country of residence. Where beneficiaries aren't individually named, the class must be described exactly as it appears in the deed (for example, "the settlor's grandchildren").
Additional Detail for Taxable Trusts
Taxable trusts must also disclose information about the trust fund — the total value of assets at registration, details of any UK land or property, shareholdings, and any business interests the trust owns or controls.
Key Deadlines
A new trust must generally be registered within 90 days of being created. You must also report any subsequent change — such as a new trustee, a change of address, or naming a beneficiary — within 90 days. For taxable trusts, trustees must additionally confirm the register is up to date each year by 31 January, even if nothing has changed.
Penalties
HMRC can charge a penalty of up to £5,000 for failing to register or keep the register updated. In practice, HMRC generally issues a warning first and does not penalise an innocent first offence; the £5,000 charge is aimed at deliberate or repeated non-compliance. Even so, trustees are personally liable for any penalty, so prompt, accurate registration matters. (TRS rules and deadlines can change, so always check the current HMRC guidance or take advice.)
