Quick answer
Most trusts in England and Wales must register with HMRC’s Trust Registration Service, typically within 90 days of creation or when they first become liable for UK tax. Trustees are generally responsible for registration, even if the trust has no tax to pay—particularly for express trusts and those holding assets worth more than £500 annually. Key trigger points include when a trust becomes liable for income tax, when it holds UK property, or when settlors pass assets (such as life insurance policies or investments) into trust. While trusts with a nil rate band of £325,000 (gov.uk — Inheritance Tax) may have no inheritance tax bill, they still typically need registering. Failure to register within the required timeframe may result in penalties. This guide explains who must register with HMRC, when deadlines apply in 2026/27, and what common scenarios require immediate action.

We know handling family affairs can feel daunting. We’ll walk you through the essentials so you can act with confidence as a trustee.
Most trusts must be listed on the Trust Registration Service and trustees are usually responsible for that step. We explain who must register and when, using plain language and clear examples.
We cover the two main routes: trusts that become liable for UK tax, and many express trusts that still need registering even with no tax to pay. We flag common moments people stumble — passing property to children, holding investments, or placing a life policy in trust.
Expect a simple checklist to decide if you need to register before you spend hours on the service. We also outline deadlines and what “within days” means so you can avoid trouble later.

Understanding trust registration in the UK and why it matters
For the 2026/27 position, see our reference guide on this topic for further information from the MP Estate Planning UK editorial team.
Deciding how to hold property for loved ones can seem complex. We explain the basics in plain terms so you can act with confidence.
What a trust is and who’s involved
A trust is simply a legal container that holds money, investments or property for someone else’s benefit. A settlor sets it up. Trustees manage the assets. Beneficiaries receive the benefits.
Trustees can change over time. When they do, records need updating. That keeps everything clear for those who inherit and for the relevant services that monitor compliance.
What the trust registration service is used for
The trust registration service is an online government record. It helps tax officials and anti-money laundering teams see who controls assets and who benefits. It is about transparency, not only tax collection.
Everyday situations that often need attention
Common triggers include a family home held for children, a share portfolio set aside for grandchildren, or a life policy placed in trust.
| Situation | Typical asset | Who acts | Why it matters |
|---|---|---|---|
| Family provision | Property | Trustees | Keeps ownership clear for beneficiaries |
| Inheritance planning | Investments | Trustee | Aids tax and legal transparency |
| Life cover | Policy in trust | Trustees | Speeds payout to named beneficiaries |
When a trust must be registered because it is liable for UK tax
Three rule changes you may need to consider (2026/27)
1. Pensions become subject to IHT from 6 April 2027. Most unused defined-contribution pension pots currently sit outside the estate for IHT — that ends on 6 April 2027 (gov.uk policy paper). HMRC estimates around 10,500 estates will face IHT for the first time as a result.
2. Business and agricultural property reliefs capped at £2.5m per person from 6 April 2026. Above the cap, only 50% relief applies — effective IHT of 20%. AIM shares dropped to 50% relief and do not use the £2.5m allowance (Saffery — APR/BPR reforms).
3. The NRB, RNRB and £2m taper threshold are frozen until 5 April 2031 following the 2024 and 2025 Budgets (gov.uk — NRB and RNRB freeze). With inflation, more estates will be pulled into IHT each year — a process commonly called “fiscal drag.”
Tax events can turn a simple family arrangement into something you must report. Below we list the common triggers that usually mean you must register a trust on the online service.
Tax triggers that mean you need to register
We’ll set out the practical “tax triggers” that usually mean you must register a trust—this is the clearest route into TRS for many trustees.
Capital Gains Tax, Income Tax and Inheritance Tax
Income tax can arise from interest, dividends or rent paid into the arrangement. When that happens, trustees often need to record the details.
Capital gains tax usually follows a sale. For example, selling shares or a second property that makes a gain will commonly mean the trust must be recorded.
Inheritance tax issues occur in longer-term plans. Gifts into the arrangement or death-related transfers can create a charge and a need to register.
Stamp duty taxes and land transactions
Property deals can trigger stamp duty rules. In England and Northern Ireland this is SDLT. Scotland uses LBTT and Wales uses LTT.
Any land or property transaction that creates a tax liability will usually push the trust into the register.
Registering to claim tax relief
“Sometimes you register not because you owe tax, but so the trust can claim relief properly.”
| Trigger | Typical tax | What it means |
|---|---|---|
| Income from assets | Income tax | Must register if trust receives taxable income |
| Sale of asset | Capital gains tax | Register when gains create a charge |
| Property purchase/sale | SDLT / LBTT / LTT | Record required for land-related tax events |
| Claiming relief | Various | Registration may be needed to claim relief |
If you are unsure whether you need register trust, our guide on register trust explains the steps and when to act.
hmrc trust registration rules for non-taxable and express trusts
A deliberately set-up arrangement can carry duties even if no tax is due. After the october 2020 rule change, many non-taxable trusts still need recorded details. We explain what that means in plain language.
What “non-taxable trust” means in practice
An non-taxable trust is one that does not currently owe UK tax. That does not always remove the duty to report.
Often the settlement holds money for grandchildren or investments with no immediate charge. Even then, trustees may need register details on the online service.
What an “express trust” is and why it is often registrable
An express arrangement is deliberately created by a settlor, typically in a deed. It can be set up during lifetime or take effect on death.
Because of the deliberate nature of the creation, most express trusts must be listed even with no tax to pay. Don’t assume “no tax” means no paperwork.
Lifetime versus will-created arrangements
Lifetime settlements start when someone is alive. Will-created ones begin on death. The timing affects when you need registered and the deadline to act.
| Type | Typical example | When action is needed |
|---|---|---|
| Non-taxable express | Money for grandchildren | Often on creation |
| Lifetime settlement | Investment account set aside | At time of creation |
| Will-created | Property held after death | When estate is settled |
Trusts that do not need to be registered
Not every arrangement called a trust has to appear on the government list. We will summarise the common exclusions so you can quickly see if your arrangement is outside the rules.
Court and statutory arrangements
Arrangements imposed by a court or created by law never need listing. These are outside the online filing system by design.
Pensions, life policies and short-term death benefits
UK-registered pension scheme arrangements are excluded. Certain life and retirement policies also fall outside the rules.
Death benefits that are paid out within two years usually do not need listing either.
Everyday exemptions
- UK-registered charities and charitable arrangements;
- Co-ownership by tenants-in-common holding property;
- Will-related arrangements that hold estate assets for up to two years;
- Bereaved-children and 18–25 funds, and some financial or commercial arrangements.
| Category | Typical example | Why it is excluded |
|---|---|---|
| Court/Statutory | Court-ordered support | Created by law, not registrable |
| Pension schemes | Occupational pension fund | Covered by pension rules |
| Short-term death benefits | Death payout within 2 years | Paid quickly to beneficiaries |
| Named products | Child Trust Fund, VCT | Not a true private arrangement |
If you are still unsure whether your arrangements need registered, ask a solicitor or adviser before you act. We can help you check the details and avoid unnecessary steps.
Non-resident trusts and UK connections that can trigger registration
When assets span countries, simple decisions can have unexpected consequences for trustees. We explain the key UK links that can pull a non-resident arrangement into the online service.
When a non-resident trust must register due to UK income
If the arrangement receives UK-source income, it can become chargeable. Examples include rent from UK property, dividends from UK companies or interest from UK accounts.
Even occasional UK income can mean you must register. Gather clear details on the payer, amounts and dates before you start.
When UK assets create a registration requirement
Ownership of UK land or property is a common trigger. Sales, rentals or labelled UK land assets usually require the trustees to act.
We advise trustees with overseas family links to check property holdings, investments and any UK bank accounts early.
- Define your non-resident status and list UK income sources.
- Confirm any UK land or property and collect deeds or tenancy details.
- Prepare extra cross-border details — addresses, ID and beneficiary connections.
| Trigger | Typical example | Action needed |
|---|---|---|
| UK income | Rent, dividends | Must register if taxable |
| UK assets | Land, property | Record details and act promptly |
When in doubt, seek professional advice. Non-resident scenarios often need careful paperwork. A short call with an adviser can prevent costly mistakes.
Registration deadlines and key dates trustees need to know
Clear dates keep trustees calm and compliant when plans change. Below we set out the main dates and what acting “within days” really means in practice.
Deadlines for trusts created after october 2020
If a trust created after october 2020 becomes liable for tax, trustees normally have 90 days from that event to complete registration.
How timing worked for older non-taxable trusts and the 2022 deadline
Non-taxable trusts created on or before 6 october 2020 had to be registered by 1 September 2022 where they were not excluded.
If you missed that date and are unsure, act promptly and seek advice rather than wait.
What “within days” means in practice
Within days means don’t leave updates until year-end accounts. Treat the online record as an ongoing compliance file.
Quick examples that need action within days: a new trustee appointed, a beneficiary detail change, or the trust suddenly becoming liable for tax after receiving income or selling an asset.
| Event | Deadline | Action |
|---|---|---|
| Trust created after october 2020 | 90 days from taxable event | Register details and update records |
| Non-taxable trust (creation on/before 6 october 2020) | By 1 September 2022 | Confirm if excluded or register |
| Change of trustee or beneficiary | Within days of change | Update online record promptly |

How to register a trust on HMRC’s Trust Registration Service
Plan ahead: appoint one main contact and collect the essential papers before you log on.
Before you start: appointing a lead trustee and gathering information
We recommend one lead trustee as the main point of contact. This person handles the Government Gateway login and supplies ID details.
Gather basic information first: the arrangement name, date of creation and whether it is express. Collect names, dates of birth, contact details and country of residence for settlors, trustees and beneficiaries.
Setting up the right Government Gateway account
Open a Government Gateway account for an organisation, not a personal login. That avoids access problems later and keeps the record linked to the right entity.
The details you’ll need and declaring land or property
Prepare details about assets, including any UK land or property. Provide clear addresses, dates of purchase and values where asked.
Lead trustees normally give National Insurance numbers and any UTR they hold. Accuracy matters — errors slow the process.
Submitting the form and what happens next
Complete the online form in one sitting if possible. After submission, taxable arrangements often receive a UTR in about 15 working days. Non-taxable entries get a URN you can view via the service.
What to do if you cannot register online
If you cannot use the online route, contact the government helpline and explain the problem. They will advise an alternative process so you can still meet your duties.
For a simple step-by-step guide to register a trust online, follow our short walkthrough.
After registration: keeping the trust compliant and avoiding penalties
Keeping the record current is a small ongoing task that saves trustees large headaches.
Keeping TRS details up to date
Trustees are responsible for updating the online file whenever things change. New trustees, a change of trustee address, altered beneficiary details or shifts in assets all need attention.
Commonly forgotten updates:
- Adding or removing a trustee;
- Changing beneficiaries’ contact information;
- Reporting the sale or purchase of land or other significant assets.
Using the UTR to report income and gains
The arrangement’s UTR is used to report any taxable income and capital gains to the tax office. Use it when you complete trust accounts or submit returns.
Penalties and when to get advice
“Deliberate failures or long delays can lead to fines, assessed case‑by‑case and sometimes reaching several thousand pounds.”
Penalties depend on whether an omission was accidental or deliberate. Good records and prompt updates protect trustees. If you are unsure — for example after a property sale, cross‑border income, or a family dispute — speak to a solicitor or tax adviser without delay.
Conclusion
Let’s pull together the main points so you leave with a clear plan.
Most arrangements will need to be listed, though a short set of exclusions removes some from the online list. The two main reasons you must act are clear: tax liability—such as capital gains tax or stamp duty taxes—and the broader rule that many express arrangements still require a record even if no tax is due.
Common triggers are changes in assets, holding UK property, or steps taken after a person’s death. Keep a simple habit: update details as they change and avoid last‑minute scrambling.
If you are unsure whether your arrangement is excluded or you have complex assets or cross‑border issues, speak to a solicitor or tax adviser. For a practical walkthrough on registering, see our guide to registering a trust in Britain.
FAQ
What does "HMRC trust registration" mean and who must register?
It’s the requirement to tell the government about a legal arrangement where someone holds assets for others. We must register when the arrangement is liable for UK tax, or when rules for express settlements or certain non-taxable trusts apply. Trustees usually handle the registration.
Who are the key people involved in a trust?
A trust normally has a settlor who creates it, trustees who manage assets and beneficiaries who benefit. Trustees carry the responsibility to keep records and to register when needed.
What is the Trust Registration Service used for?
It’s the online service to record details of the arrangement, the people involved and taxable events. It also issues identifiers such as a reference number used for tax returns and communications.
When does a trust need registering because of tax?
You must register if the arrangement is liable for Income Tax, Capital Gains Tax or Inheritance Tax in the UK. Common triggers include income from investments, gains on sold assets and taxable lifetime gifts.
How do capital gains and income tax affect the need to register?
If the arrangement realises gains or receives taxable income and is liable to pay tax, registration is required so those amounts can be reported and taxed correctly.
Do land or property transactions create a registration duty?
Yes. Stamp duty land tax, land and buildings transaction tax (Scotland) or land transaction tax (Wales) can make the arrangement reportable, especially where UK land is held or transferred.
Can I register to claim tax relief?
You can use the service to register where tax reliefs apply. Registration helps ensure trustees can make proper claims and provide HMRC with the necessary information.
What is a non-taxable arrangement in practice?
Some arrangements never create a UK tax liability, such as certain pension schemes or short-term death benefits. These can be outside the need to register, though some express arrangements still require entry.
What is an express arrangement and why might it still be registrable?
An express arrangement is a deliberately created settlement with documented terms. Even if it currently has no tax to pay, it may need recording because it can be traced and identified by authorities.
Are lifetime-created arrangements treated differently from those in a will?
Yes. Arrangements created during a lifetime can trigger immediate duties. Will-based arrangements often have specific transitional rules and short windows where registration may not be required.
Which arrangements do not need registering?
Court-imposed arrangements, some statutory bodies and clearly excluded products such as many occupational pensions and qualifying life policies are outside the service. Certain co-ownership and short-term will provisions may also be exempt.
What about charitable arrangements and co-ownership?
Charitable arrangements with recognised status are generally exempt. Simple co-ownership where people hold property together (tenants in common) is usually not a registrable arrangement, provided it doesn’t operate as a settlement.
When must non-resident arrangements register because of UK connections?
If a non-resident arrangement receives UK income or holds UK property, trustees may need to register. The connection is what matters, not the trustees’ country of residence.
What are the deadlines for arrangements created after 6 October 2020?
New arrangements created after that date generally require prompt registration once they meet the test for tax liability or the express rules. Trustees should act quickly to avoid late penalties.
How do timing rules work for older non-taxable arrangements?
Certain older arrangements had set deadlines to enter details. If the arrangement remained non-taxable but became reportable later, trustees must register within a specified number of days from the change.
What does “within days” mean when circumstances change?
It means you must update the record promptly — usually within 30 days of becoming liable or of a significant change. Acting quickly reduces the risk of penalties.
How do we start the online registration process?
Appoint a lead trustee, gather identity and asset details, and set up an appropriate Government Gateway organisation account. Then complete the online form with the required people and asset information.
What documents and details are needed to register?
You’ll need names and dates of birth for trustees, settlors and beneficiaries, descriptions of assets including UK land, and any relevant tax references. Accurate contact details are essential.
How do we declare UK land or other reportable assets?
Provide clear descriptions, ownership shares and dates of acquisition. If land is involved, include the address and any transaction details that show tax liability.
What happens after submitting the registration?
You receive a reference number to use on tax returns. Keep records and update the service whenever trustees change or beneficiary details evolve.
What if we cannot register online?
Contact the service helpline for guidance. In some circumstances an agent or adviser can register on your behalf, or HMRC can provide alternative arrangements.
How should trustees keep details up to date?
Review the record regularly and update within the required timeframes when trustees, beneficiaries or assets change. Timely updates prevent mistakes and possible fines.
How is the reference number used for reporting income and gains?
The reference links the arrangement to tax returns and payments. Use it when reporting income, capital gains or claiming reliefs so HMRC can match records.
What penalties apply for late or deliberate failure to register or update?
Penalties vary by severity. Late or missing entries can lead to fines; deliberate withholding of information may trigger larger penalties. Honest mistakes are treated more leniently if corrected swiftly.
When should we speak to a solicitor or tax adviser?
Seek advice if the arrangement is complex, involves cross-border assets, major property or large investments, or if you face potential penalties. Professional help protects the family and reduces risk.
What happens if a trust is not registered — consequences and practical risks for trustees
Missing a Trust Registration Service deadline is not simply an administrative oversight. HMRC treats late or absent registration as a compliance failure, and the consequences can affect trustees personally. More broadly, in our experience, an unregistered trust often signals wider gaps in how the arrangement is being managed — gaps that registration itself can prompt trustees to address.
HMRC penalties for late or missing registration
Where a trust is required to be registered and is not, HMRC may issue financial penalties. Under the current penalty framework, a first offence typically attracts a fixed penalty of £100, rising to £200 for a second late-registration failure. Where HMRC determines that a failure was deliberate, the position becomes considerably more serious: daily penalties may apply, and in cases involving unpaid tax, a surcharge of up to 5% of the tax at stake can be added on top. You can review HMRC’s published approach to Trust Registration Service penalties via GOV.UK’s Trust Registration Service guidance. Penalties aside, an unregistered taxable trust may also face practical difficulties — for example, delays in obtaining a Unique Taxpayer Reference, which is generally required before a self-assessment return can be filed.
Registration deadlines trustees should keep in mind
For new taxable trusts created on or after 6 April 2021, registration must typically be completed within 90 days of the trust becoming liable to tax — or within 90 days of creation where that is the trigger. Pre-existing non-taxable express trusts were generally required to have registered by 1 September 2022. Trustees who are uncertain whether their trust fell into a registrable category before that date should take specific advice, as HMRC’s approach to late registration in borderline cases may depend on the individual facts.
Registration as a prompt to review the whole arrangement
Our team encourages trustees to treat TRS registration not as a one-off compliance exercise but as an annual touchpoint to look at the trust more holistically. Is the Letter of Wishes still current? Does the trust structure still serve the settlor’s original purpose? Was the trust deed drafted in a way that reflects how the family’s circumstances have since changed? These are questions a government guidance page will not raise — but they are often the most valuable ones. Registration, in this sense, may be the moment a trustee realises the arrangement needs a fuller review.
Common questions about UK trust registration
Does a trust have to be registered in the UK?
In many cases, yes — though the answer depends on the type of trust and whether it has any UK tax liabilities. Broadly, any UK trust that incurs a liability to Income Tax, Capital Gains Tax, Inheritance Tax, Stamp Duty Land Tax or other specified taxes must register with HMRC’s Trust Registration Service. Beyond taxable trusts, most express trusts — those deliberately created by a settlor, as opposed to arising by operation of law — are also generally required to register even if they have no current tax liability, unless a specific exemption applies. Certain arrangements, such as bare trusts holding a single premium life policy and trusts holding pension death benefits, may be exempt. If you are unsure whether a particular arrangement needs to register, a regulated tax adviser or solicitor can assess the specific facts.
What happens if a trust is not registered?
Trustees who miss a registration deadline may face fixed penalties starting at £100 for a first offence and £200 for a second. Where HMRC regards a failure as deliberate, daily penalties and a surcharge of up to 5% of any tax at stake may also apply. Practically, an unregistered taxable trust may be unable to obtain the Unique Taxpayer Reference needed to file tax returns, which can create compounding compliance problems. Timely registration is generally the simplest way to avoid these difficulties.
Is there a register of trusts in the UK?
Yes. The Trust Registration Service, operated by HMRC, is the central register for trusts with a UK nexus. It is not, however, a public register in the same way that Companies House is. Access to trust information held on the TRS is restricted: it is available to HMRC, certain law enforcement bodies, and — in limited circumstances — to third parties who can demonstrate a legitimate interest. You can read about access rights on GOV.UK’s Trust Registration Service guidance page.
How to find if a trust exists?
There is no straightforward public-facing search tool that allows a member of the public to look up whether a specific trust has been registered. If you are a trustee or a potential beneficiary trying to establish whether a trust exists, the most reliable routes are typically to examine the original trust deed or will, speak with the solicitor who drafted the arrangement, or — where a family member has died — review the estate administration papers. Beneficiaries do have certain rights to information about a trust under general trust law, though the scope of those rights can vary depending on the nature of the trust. A solicitor experienced in trust and probate matters can advise on the specific position.
How much does it cost to register a trust in the UK?
Registering a trust with HMRC’s Trust Registration Service is free of charge — there is no government fee for the registration itself. However, the process requires detailed information about the trust, its assets, the settlor, all trustees, and the beneficial class, and many trustees engage a solicitor or accountant to handle registration on their behalf. Professional fees for that work will vary depending on the complexity of the trust and the adviser instructed.
Closing a trust on the TRS — what must trustees do?
When a trust winds up, trustees are generally required to notify HMRC via the Trust Registration Service and update the register to reflect that the trust has come to an end. This typically involves confirming the date on which the trust ceased and ensuring all tax obligations have been met before the record is closed. Failing to update the register when a trust ends can leave trustees with ongoing compliance obligations they believe they have discharged. HMRC’s guidance on closing a trust registration is covered within the broader Manage your trust’s registration guidance on GOV.UK. Our team would recommend taking professional advice at the point of winding up to ensure the closure is recorded correctly and that no outstanding tax or reporting obligations remain.
