How to Register a Trust with HMRC

If you have been asked to act as a trustee for a family member, or you have set up a trust to protect money or property for someone else, you may have been told that you now need “to register a trust with HMRC”. For many people, this instruction comes with very little explanation, and the terminology alone can feel overwhelming.

It is extremely common for trustees to ask:

How do I register a new trust with HMRC?
Do you need to register a trust with HMRC if there is no tax to pay?
What is the trust registration process?
How do you register a trust with HMRC correctly and on time?

This guide answers all of those questions in plain English. It explains how UK trust registration works, when registration is required, how to use the Trust Registration Service (TRS), and what your responsibilities are after registration. It also explains when professional support can be valuable, and why many trustees choose to work with Every Step Financial Services for clarity and peace of mind.

Summary

This guide explains how to register a trust with HMRC using the Trust Registration Service (TRS). It covers what a trust is, who must register, which trusts are exempt, and the expanded post-2021 rules that mean many non-taxable trusts must now be registered. You will learn the trust registration process step by step, including deadlines, the information required, what happens if you miss the deadline, and your ongoing duties as a trustee. It also explains when to seek professional help and how Every Step Financial Services can support trustees with UK trust registration and wider financial planning.

What Is a Trust?

A trust is a legal arrangement where assets are held and managed by one person or group of people for the benefit of someone else. It is often used to protect money, control how it is used, or ensure it is passed on at the right time.

A simple way to understand a trust is to think of it as a secure box with rules attached.

One person puts assets into the box. This person is called the Settlor.
One or more people are responsible for looking after the box and following the rules. These people are the Trustees.
One or more people will benefit from what is in the box, either now or in the future. These people are the Beneficiaries.

For example, a grandparent may place money into a trust for a grandchild. The grandparent is the settlor, the parent may act as trustee, and the child is the beneficiary. The trust sets out when and how the money can be used.

Trusts are commonly used for:

Children and grandchildren
Vulnerable or disabled beneficiaries
Estate and inheritance planning
Holding property or investments

Once a trust exists, the trustees take on legal responsibilities, including deciding whether the trust must be registered with HMRC.

Why Trusts Must Be Registered with HMRC

You may wonder why a private family arrangement needs to be reported to HMRC at all. The reason is transparency and accountability.

UK law now requires HMRC to maintain a central register of trusts. This helps prevent the misuse of trusts for tax evasion, money laundering, or hiding assets. It also allows HMRC to monitor whether trusts generate taxable income or gains.

Registering a trust does not automatically mean tax is due. In many cases, no tax will ever be payable. Registration simply tells HMRC that the trust exists and who is involved.

The official system used for this purpose is the Trust Registration Service (TRS). This is the only way to register a trust with HMRC and forms part of your legal duties as a trustee.

Trust registration is often best considered alongside wider planning, such as financial planning and inheritance strategies.

Does Your Trust Need to Be Registered?

This is one of the most important questions trustees ask: do you need to register a trust with HMRC?

The rules changed significantly in recent years, and many trusts that previously did not need to be registered now fall within scope.

Trusts that usually must be registered

You will normally need to register your trust if it:

Has a UK tax liability, such as Income Tax, Capital Gains Tax, or Inheritance Tax
Holds UK land or property
Was created by a will and continues for more than two years after death
Was created after September 2021 and does not fall under a specific exemption

Crucially, a trust may need to be registered even if it has no tax to pay. This is the part that often surprises trustees.

Simple arrangements such as bare trusts holding investments for children may still require UK trust registration.

Common exemptions

Some trusts are excluded from registration, including:

Junior ISA and child bank account arrangements
Certain life insurance policy trusts that pay out within two years
Trusts for disabled persons meeting specific criteria
Will trusts wound up within two years of death

If you are unsure, professional confirmation can prevent mistakes. Many trustees choose to book a consultation to avoid registering unnecessarily or missing an obligation.

Trust Registration Deadlines Explained

Once you know you must register, the next key question is timing.

For most trusts, the deadline is 90 days from the date the trust is created or becomes registerable. This date is often referred to as a trigger event.

For example:

If a trust is created and funded on 1 March, the 90-day clock starts on that date.
The paperwork delay does not extend the deadline.

Trusts created by a will generally have a longer timeframe, typically up to two years from the date of death.

Missing the deadline does not automatically mean severe penalties, but it does create unnecessary risk and stress.

Information You Need Before Registering

Registering a trust is much easier if you gather all the information in advance.

Details about the trust

Trust name
Date created
Type of trust

Details about the people involved

For the settlor, all trustees, and all beneficiaries:

Full name
Date of birth
National Insurance number (or address if unavailable)

Details about trust assets

Cash amounts
Property addresses
Investment descriptions

Lead Trustee

One trustee must be appointed as the Lead Trustee. This person acts as the main contact with HMRC and receives correspondence, including the Unique Taxpayer Reference (UTR).

This role does not give extra authority, but it carries administrative responsibility.

Step-by-Step: How to Register a Trust with HMRC

If you are asking “how do you register a trust with HMRC?” or even searching “how do i register a trust with hmrc”, the process follows these steps:

Access the Trust Registration Service on the GOV.UK website
Sign in or create a Government Gateway account
Claim the trust by entering identifying details
Complete sections for the settlor, trustees, beneficiaries, and assets
Review and submit the registration

After submission, HMRC will issue a Unique Taxpayer Reference (UTR) by post to the lead trustee.

This confirms that the trust is officially registered.

What Happens If You Miss the Deadline?

Many trustees worry about penalties if they register late. In practice, HMRC often takes a proportionate approach.

First-time, non-deliberate failures may result in reminders or small fixed penalties
Deliberate or repeated failures can lead to more serious consequences

The best approach is always to register as soon as possible, even if late.

Ongoing Responsibilities After Registration

Registering a trust is not a one-off task. Trustees must keep the Trust Registration Service up to date.

You must update HMRC within 90 days if:

Trustees change
Beneficiaries change
Personal details change
Trust assets change materially

This ongoing duty is an important part of trustees’ responsibilities in the UK.

DIY or Professional Support?

Some trustees are comfortable completing UK trust registration themselves, particularly for simple trusts. Others prefer reassurance.

You should strongly consider professional help if:

The trust holds property or business assets
Any party is a non-UK resident
The trust forms part of estate or inheritance tax planning
You are unsure whether registration is required

Trusts often interact with wider matters such as savings and investments, retirement planning, and inheritance tax considerations.
