Setting up a trust in the UK is one of the most effective ways to protect family assets, plan for inheritance tax, and secure your beneficiaries’ financial future. Whether you are arranging your estate, providing for a vulnerable relative, or passing wealth to your children, choosing the right type of trust is critical.

This guide explains the main types of UK trusts, how to set up a trust step by step, the legal and tax framework you need to know, and how to avoid common pitfalls. At Target Accounting UK, our chartered tax advisers have helped hundreds of families and business owners structure trusts that meet HMRC compliance requirements and deliver long-term tax efficiency.

Key Takeaways

• A trust is a legal arrangement where trustees hold and manage assets on behalf of beneficiaries, governed by a written trust deed.
• The main UK trust types include discretionary trusts, bare trusts, interest in possession trusts, accumulation trusts, mixed trusts, and trusts for vulnerable beneficiaries.
• Setting up a trust involves selecting beneficiaries, choosing trustees, identifying assets, drafting a trust deed, and registering with the HMRC Trust Registration Service (TRS) where required.
• Trusts and trustees are taxed separately from individuals, with their own income tax, capital gains tax, and inheritance tax rules.
• Professional advice is strongly recommended because trust law and tax rules are complex and getting it wrong can be costly.

Overview of Trusts in the UK

A trust is a legal arrangement where one party (the settlor) transfers assets to another party (the trustees) to hold and manage on behalf of named individuals or groups (the beneficiaries). Trusts are widely used for estate planning, protecting family wealth, providing for minors or vulnerable adults, and managing how assets are distributed after death.

Three parties are involved in every UK trust:

• Settlor – the person who creates the trust and transfers assets into it.
• Trustees – the legal owners of the trust assets, responsible for managing them in line with the trust deed and UK tax law.
• Beneficiaries – the people who benefit from the trust, either by receiving income or capital.

The trust deed is the central legal document. It sets out the terms, the powers of the trustees, the rights of the beneficiaries, and how the trust must be administered. A trust can be created during the settlor’s lifetime (a lifetime trust) or established through a will (a will trust) that takes effect on death.

Choosing the right trust structure depends on your goals, the needs of your beneficiaries, and the tax position of your estate. The next sections explain each type in detail.

Discretionary Trusts

A discretionary trust gives the trustees full discretion over how, when, and to whom income and capital are distributed from a defined class of potential beneficiaries. No beneficiary has a fixed entitlement until the trustees decide to make a payment.

Key features:

• Trustees decide which beneficiaries receive distributions and how much.
• Beneficiaries have no automatic right to income or capital.
• Useful for families with changing financial needs or to protect assets from divorce, bankruptcy, or means-tested benefit assessments.
• Falls within the relevant property regime for inheritance tax, including 10-year periodic charges and exit charges when capital leaves the trust.

Tax treatment:

• Trust income is taxed at the trust rate of 45% on non-dividend income and 39.35% on dividend income (the dividend trust rate remains the additional rate).
• Income tax is not charged where the trust’s total income is £500 or less in a tax year, although where a settlor has created multiple trusts this £500 de minimis is divided.
• Trustee Capital Gains Tax annual exempt amount is £1,500 (half the individual allowance).
• When trustees distribute income to a beneficiary, the payment carries a 45% tax credit, which a basic-rate or non-taxpaying beneficiary can reclaim from HMRC.

Discretionary trusts are particularly effective for grandparents wanting to fund education for future grandchildren, or business owners passing on shares while retaining control through the trustees.

Bare Trusts

A bare trust (also called an absolute trust or simple trust) is the most straightforward structure. Assets are held in the name of the trustee, but the beneficiary has an absolute right to both the capital and any income. The beneficiary can demand the assets outright once they reach age 18 in England, Wales, and Northern Ireland (16 in Scotland).

Key features:

• The beneficiary is fixed and cannot be changed once the trust is created.
• Trustees hold legal title only; they must follow the beneficiary’s instructions once they reach the age of majority.
• Commonly used by parents and grandparents to hold investments or cash for children.

Tax treatment:

• Income and gains are treated as the beneficiary’s, not the trustees’.
• The beneficiary uses their own personal allowances, including the Capital Gains Tax annual exempt amount, dividend allowance, and savings allowance.
• Anti-avoidance rule: if a parent settles a bare trust for their own minor unmarried child and the income from that gift exceeds £100 in a tax year, the income is taxed on the parent rather than the child.

Bare trusts are simple, transparent, and tax-efficient, which is why they remain popular for straightforward family gifts.

Interest in Possession Trusts

In an interest in possession trust (also called a life interest trust), the named beneficiary, known as the life tenant, has an immediate right to the income from the trust assets, or to enjoy the assets (for example, living rent-free in a property), for life or for a defined period. The capital usually passes to other beneficiaries, called the remaindermen, when the life interest ends.

Key features:

• The life tenant receives all trust income as it arises.
• Capital is preserved for the remaindermen, often a spouse first, then children.
• Frequently used in second-marriage situations to provide for a surviving spouse while protecting capital for children from a previous relationship.

Tax treatment:

• Most lifetime transfers into an interest in possession trust created on or after 22 March 2006 are treated as chargeable lifetime transfers for inheritance tax and fall within the relevant property regime (subject to 10-year and exit charges).
• Trustees pay income tax at the basic rate (20%) on non-dividend income and the dividend ordinary rate on dividend income; the life tenant then receives the income with a tax credit and pays any further tax due at their personal marginal rate.
• On the death of a life tenant of an immediate post-death interest (IPI) trust created by will, the trust assets form part of the life tenant’s estate for inheritance tax purposes.

The 2006 Finance Act significantly changed the tax treatment of these trusts, so always seek advice before creating one today.

Accumulation Trusts

An accumulation trust allows the trustees to accumulate income within the trust rather than distributing it to beneficiaries each year. The accumulated income is added to the capital and may be paid out later, in line with the trust deed.

Key features:

• Trustees can build up income inside the trust until beneficiaries need it.
• Useful where beneficiaries are minors or where their financial circumstances may change.
• Often combined with discretionary powers, creating an accumulation and discretionary style structure.

Tax treatment:

• Treated as a relevant property trust: income above the £500 de minimis is taxed at 45% (39.35% on dividends).
• Trustee CGT annual exempt amount is £1,500.
• When income is later distributed, beneficiaries receive a 45% tax credit and can reclaim any excess if their own marginal rate is lower.

Accumulation trusts are well suited to long-term planning, especially for younger beneficiaries who do not yet need access to funds.

Mixed Trusts

A mixed trust combines two or more trust types within a single arrangement. For example, part of the trust may be set up as an interest in possession for a surviving spouse, while another part operates as a discretionary trust for the children.

Key features:

• Each portion of the trust is taxed according to its specific type.
• Offers flexibility for blended families or estates with different generations of beneficiaries.
• Requires careful drafting and ongoing administration to keep each element compliant.

Mixed trusts are powerful but more complex, so administration costs and trustee responsibilities tend to be higher.

Trusts for Vulnerable Beneficiaries

A trust for a vulnerable beneficiary (sometimes called a disabled person’s trust) qualifies for special tax treatment under Schedule 1A of the Finance Act 2005. A vulnerable beneficiary is either:

• A disabled person who is entitled to qualifying benefits such as Attendance Allowance, Personal Independence Payment, the daily living component of Adult Disability Payment in Scotland, or the higher or middle rate care component (or higher rate mobility component) of Disability Living Allowance, or
• A bereaved minor under 18 who has lost a parent.

Tax advantages:

• Trustees can elect for the trust’s income tax and capital gains tax to be calculated as if the income and gains arose directly to the vulnerable beneficiary, often producing a much lower tax liability.
• The CGT annual exempt amount is £3,000 (the full individual rate) instead of the £1,500 standard trustee allowance.
• Trusts that meet the qualifying conditions are exempt from the 10-year periodic inheritance tax charges that apply to most relevant property trusts.
• Means-tested benefits and care costs are generally protected because the assets are owned by the trust, not the beneficiary.

A vulnerable beneficiary election (form VPE1) must be filed jointly by the trustees and the beneficiary to claim these reliefs.

How to Set Up a Trust in the UK: Step-by-Step

Setting up a trust is a structured legal process. Each step has tax and legal consequences, so professional guidance is essential.

Step 1: Define Your Objectives

Decide what you want the trust to achieve. Common goals include reducing inheritance tax, protecting assets for minors, providing for a disabled relative, ring-fencing a property, or controlling business succession.

Step 2: Choose the Right Type of Trust

Match your objectives to the right structure. A bare trust suits simple gifts to children, a discretionary trust offers maximum flexibility, and a vulnerable beneficiary trust delivers tax savings for disabled relatives.

Step 3: Identify Beneficiaries and Assets

List the beneficiaries (named individuals or a class such as “my grandchildren”) and the assets going into the trust. Assets can include cash, shares, investment portfolios, life insurance policies, residential or commercial property, and business interests.

Step 4: Appoint Trustees

You need at least one trustee to create a valid trust, although it is usually best practice to appoint at least two and no more than four trustees. Trustees should be people you trust completely, ideally a mix of family members and a professional such as a solicitor or accountant.

Step 5: Draft the Trust Deed

The trust deed is a binding legal document that sets out:

• The settlor, trustees, and beneficiaries.
• The assets being settled.
• Trustee powers, duties, and any restrictions.
• Distribution rules and the trust’s duration.

A solicitor or specialist tax adviser should draft the deed to ensure it is enforceable and tax-efficient.

Step 6: Transfer Assets into the Trust

Once the deed is signed, assets must be legally transferred into the trustees’ names. For property, this means a Land Registry transfer; for investments, a re-registration with the platform or registrar.

Step 7: Register with HMRC

Most UK trusts must register with the HMRC Trust Registration Service (TRS). Express trusts that hold assets, generate income, or trigger UK tax liabilities must register, generally within 90 days of creation. Failure to register can result in penalties.

Step 8: Manage Ongoing Compliance

Trustees must:

• File a Trust and Estate Tax Return (SA900) each year if the trust has income or gains to report.
• Issue an R185 (Trust Income) certificate to beneficiaries who receive distributions.
• Keep accurate records of income, distributions, and decisions.
• Update the TRS within 90 days of any material change to the trust details.

Cost of Setting Up a Trust

Setting up a trust in the UK typically costs between £1,000 and £10,000+, depending on complexity, asset value, and whether ongoing administration services are included. Larger or cross-border arrangements can cost considerably more.

Benefits of Setting Up a Trust

A well-structured trust can deliver significant advantages:

• Inheritance tax planning – assets gifted into certain trusts can fall outside your estate after seven years, potentially saving 40% inheritance tax.
• Asset protection – trust assets are separate from the settlor’s personal estate, shielding them from creditors, divorce settlements, and care fees in many cases.
• Control over distribution – you can decide who benefits, when they benefit, and under what conditions.
• Provision for vulnerable family members – preserves means-tested benefits while ensuring financial security.
• Privacy – unlike wills, trust details are generally not made public.
• Business succession – shares held in trust can pass smoothly between generations without disrupting company control.

Acting as a Trustee: Duties and Responsibilities

Being a trustee is a serious legal role with fiduciary duties. Trustees must:

• Act honestly, in good faith, and in the best interests of the beneficiaries.
• Follow the trust deed and applicable law (Trustee Act 2000).
• Avoid conflicts of interest and never profit personally from the trust without express authority.
• Invest trust assets prudently, taking advice where needed.
• Keep accurate records, accounts, and minutes of decisions.
• File tax returns and meet HMRC reporting deadlines.

Trustees can be held personally liable for breaches of trust, so professional advice is highly recommended, particularly for larger or more complex trusts.

How and When a Trust Ends

A trust can come to an end in several ways:

• Beneficiary becomes absolutely entitled – for example, when a bare trust beneficiary reaches the age of majority.
• Trust period expires – modern trusts often have a maximum duration of up to 125 years under the Perpetuities and Accumulations Act 2009.
• All assets distributed – once the assets have been paid out, the trust ceases to exist.
• Trustees exercise a power to wind up – if the deed permits.

Before closing a trust, trustees must settle any outstanding tax (income tax, CGT, IHT exit charges), distribute remaining assets, deregister from the TRS, and keep records for at least 12 years.

Common Mistakes to Avoid When Setting Up a Trust

• Failing to register with the HMRC Trust Registration Service within 90 days.
• Choosing the wrong type of trust for your goals.
• Appointing only one trustee, which creates risk if they die or lose capacity.
• Not updating the trust deed or TRS after major life events such as marriage, divorce, or bereavement.
• Overlooking the seven-year rule on lifetime gifts into trust.
• Ignoring annual compliance: trust returns, 10-year charges, and TRS updates.

Frequently Asked Questions

What is the main purpose of setting up a trust in the UK?

The main purpose of a trust is to hold and manage assets on behalf of someone else, typically to protect family wealth, plan for inheritance tax, provide for vulnerable relatives, or control how and when assets are distributed.

How much does it cost to set up a trust in the UK?

Setting up a trust usually costs between £1,000 and £10,000, depending on complexity, asset type, and the legal advice required. Ongoing administration and tax filing fees apply each year.

How many trustees do I need?

You need at least one trustee to create a valid trust, but appointing two to four trustees is recommended. This provides continuity if one trustee resigns, dies, or loses capacity, and ensures decisions are properly considered.

Do I have to register my trust with HMRC?

Yes, most express UK trusts must register with the Trust Registration Service within 90 days of being created, even if there is no tax liability. Penalties apply for late or non-registration.

What is the difference between a discretionary trust and a bare trust?

In a discretionary trust, the trustees decide which beneficiaries receive payments and when. In a bare trust, the named beneficiary has an absolute right to the assets and income, and gains the legal entitlement at age 18 (16 in Scotland).

How are trusts taxed in the UK?

Discretionary and accumulation trusts pay income tax at 45% on non-dividend income and 39.35% on dividends, with a £500 de minimis exemption. Trustees also have a Capital Gains Tax annual exempt amount of £1,500, rising to £3,000 for trusts with a vulnerable beneficiary. Bare trusts are taxed on the beneficiary, while interest in possession trustees pay basic-rate tax and the life tenant accounts for any further liability.

Can a trust reduce my inheritance tax bill?

Yes, gifting assets into certain trusts during your lifetime can remove them from your estate after seven years, potentially saving 40% inheritance tax. The exact saving depends on the trust type, the value gifted, the available nil-rate band, and your overall estate planning strategy.

Can I be a trustee of my own trust?

Yes, settlors can act as trustees of their own trust, but this can create tax complications, especially with settlor-interested trusts where the settlor or their spouse can benefit. Speak to a tax adviser before taking this approach.
