We explain the HMRC Trust Register in plain English. It is the official route to record who benefits from a trust and, when needed, to obtain a Unique Taxpayer Reference (UTR) via the Trust Registration Service (TRS).
Our aim is to make the process feel manageable. We set out what matters for British homeowners and families, and why banks, insurers and financial providers may ask for proof that a trust is on the register before they will act on the trustees’ instructions.
Even if a trust pays no tax, registration may still be required. The rules changed significantly after the implementation of the Fifth Money Laundering Directive in October 2020, and deadlines now carry real consequences — including financial penalties and anti-money laundering concerns.
We introduce the key players — settlors, trustees and beneficiaries — and explain the practical information you must supply. We also outline what happens after registration, how to keep the record up to date, and the common mistakes that cause delay.
Key Takeaways
- The TRS is the single route for trust registration and obtaining a UTR (for taxable trusts) or URN (for non-taxable trusts).
- Registration can be required even when no tax is due — most UK express trusts must now be registered.
- Banks and financial providers routinely demand proof of TRS registration before acting on trustees’ instructions.
- Deadlines matter — late filings can lead to penalties starting at £100 and rising for deliberate non-compliance.
- We break the process into clear steps so you can avoid common delays and stay compliant.
Understanding the Trust Registration Service and why it exists
We explain what the Trust Registration Service does and who it protects. The TRS was introduced in 2017 for taxable trusts, then expanded significantly under the Fourth and Fifth Money Laundering Directives. From 6 October 2020, most UK express trusts — whether taxable or not — must be registered on the TRS. This includes the vast majority of lifetime trusts and will trusts that families set up to protect their homes and assets.
The TRS is HMRC’s central record of beneficial ownership. It holds information on the settlor (the person who created the trust), the trustees (who manage the trust assets), beneficiaries, key dates and sometimes the nature of the trust assets. A registered TRS entry will show either a UTR for taxable trusts or a URN for non-taxable ones.
Organisations such as banks, investment providers and solicitors’ firms routinely ask for TRS evidence and your URN or UTR. Under anti-money laundering regulations, they must check beneficial ownership details against HMRC records and report any material discrepancies. That is why accuracy matters: a simple change of trustees, a property transaction or even a withdrawal from a trust bank account can be paused until the financial institution sees the correct, up-to-date TRS details.
- Central purpose: improve transparency around beneficial ownership and prevent the misuse of trust arrangements to hide assets or launder money.
- What is held: names, dates of birth, addresses, beneficiary details and sometimes a description of the trust assets.
- Practical effect: providers may delay or refuse transactions until they see current TRS proof — having your URN or UTR ready avoids unnecessary hold-ups.
It is worth emphasising that unlike Companies House, the TRS register is not publicly accessible. Information is only shared with regulated entities and law enforcement in specific circumstances. This is an important distinction for families who value privacy — your trust details are not visible to the general public.
Who must register on the HMRC Trust Register
We break the scope down so you can quickly spot whether you need to act. There are three broad groups to check: trusts with a UK tax liability, most UK express trusts even if non-taxable, and overseas trusts with a UK connection.
UK and non-UK trusts with a UK tax liability
If a trust has any UK tax liability — whether income tax (currently 45% for non-dividend trust income, 39.35% for dividends), capital gains tax (24% on residential property, 20% on other assets), inheritance tax (40% on the taxable estate above the nil rate band), stamp duty land tax (SDLT), land transaction tax (Wales), or land and buildings transaction tax (Scotland) — it must be registered on the TRS. That applies regardless of whether the trust is UK-resident or established overseas.
Non-taxable UK trusts that still need registration
Many families assume no tax means no paperwork. That is not the case. Since the Fifth Money Laundering Directive came into force, most UK express trusts in existence on or after 6 October 2020 must be registered on the TRS, even when they have no current tax liability. This catches the majority of family trusts — including discretionary trusts set up to protect the family home — that many people assumed were “under the radar.” England invented trust law over 800 years ago, and the TRS is the first time the government has required comprehensive registration of these arrangements.
Overseas trusts brought into scope
An overseas trust must be registered on the TRS if it has at least one UK-resident trustee, if it enters into a business relationship with a UK-regulated entity (for example, a bank, investment provider or solicitors’ firm), or if it acquires UK land or property. Overseas trusts with a UK tax liability must also register.
Trusts created from 1 September 2022 onwards must be registered within 90 days of creation. Significant changes — such as a new trustee appointment or a change of beneficiaries — must also be notified within 90 days of the event.
- Typical events requiring an update: appointment or resignation of a trustee, addition of new beneficiaries, changes to the settlor’s or trustees’ contact details, or a significant change in the trust assets.
- If you are unsure whether your trust needs registration, check early — failing to register can lead to penalties and may cause banks and providers to freeze transactions involving the trust.

Trusts that are excluded from registration and common grey areas
There are clear exclusions and a few grey areas that commonly confuse families. We summarise the typical categories below and highlight where you should check further or seek specialist advice.
Common exclusions include UK-registered pension schemes, registered charities, trusts holding life insurance policies that only pay out on death or critical illness, and pilot trusts holding £100 or less that were created before 6 October 2020 (provided no further assets are added). Trusts imposed or varied by court order and statutory trusts arising from joint property ownership (such as a co-ownership trust of land) are also typically outside scope.
Special family examples: bereaved minor trusts, trusts for vulnerable beneficiaries (such as disabled person’s trusts), Child Trust Funds and Junior ISAs are often excluded. Will trusts where the personal representatives distribute all assets to the beneficiaries within two years of the deceased’s death are also generally outside the registration requirement.
| Exclusion | Typical example | When action may still be needed |
|---|---|---|
| Pensions & charities | Workplace pension; registered charity fund | Only if the trust has a separate UK tax liability not covered by the pension or charity’s own registration |
| Children’s accounts | Junior ISA; Child Trust Fund | An investment portfolio held on bare trust for a minor often requires registration — the Junior ISA and CTF exemptions are narrow |
| Pilot trust / small asset rule | Trusts created before 6 October 2020 holding £100 or less | Becomes registerable if further assets are added or the trust acquires a tax liability |
One area that commonly causes confusion is bare trusts. A parent holding a child’s bank account may fall within an exclusion, but a portfolio or property held on bare trust for a minor usually requires registration. It is also worth understanding that bare trusts offer no inheritance tax (IHT) planning benefit — the beneficiary is treated as owning the assets outright for tax purposes. Under the principle in Saunders v Vautier, once the beneficiary reaches 18 (16 in Scotland), they can collapse the trust entirely and demand the assets. Bare trusts also cannot protect assets against care fees or divorce. If there is any UK tax liability, the exclusions do not apply, and a failure to register can result in penalties.

What you need before you register a trust with HMRC
Getting the right information together first makes the online process far quicker and reduces costly errors. Gather your core documents and check all names, dates and details against the trust deed before you start the TRS registration.
Core details HMRC expects
We advise collecting the following before you begin:
- The trust’s full name and date of creation (as stated in the trust deed).
- Full details for each trustee and the settlor — including full names, dates of birth, National Insurance numbers (where available), addresses and contact details.
- Beneficiary identities — either named individuals with their personal details, or a description of the class of beneficiaries (for example, “all children and grandchildren of the settlor”) as set out in the trust deed. Discretionary trusts — the most common type of family trust in England and Wales — typically define beneficiaries as a class rather than naming specific individuals.
Lead trustee role and joint liability
The lead trustee is the main point of contact for HMRC and the TRS. They are responsible for keeping login credentials and reference numbers safe, and for completing filings on time.
However, all trustees remain jointly and severally liable for the accuracy of the TRS record and any penalties that arise from non-compliance. One trustee handling the administration does not remove responsibility from the others — this is a shared legal obligation. Remember, a trust is a legal arrangement, not a separate legal entity — the trustees are the legal owners of the trust property and bear personal responsibility for compliance.
When to appoint an agent
Consider appointing an agent when there are multiple beneficiaries, overseas connections, frequent changes to trust details, or where the trustees are not comfortable navigating the online system. A specialist agent — such as a solicitor or trust administration firm — can reduce mistakes and speed up the registration process. At MP Estate Planning, we handle TRS registration as part of our trust setup service, so the trust is registered correctly from day one.
| Task | Who provides the information | Why it matters |
|---|---|---|
| Identity details | Settlor & trustees | Must match the trust deed exactly — discrepancies cause delays |
| Beneficiary list or class description | Trustees (from the trust deed) | Shows who benefits and satisfies anti-money laundering requirements |
| Details of anyone who can direct or influence the trustees | Trustees / settlor | HMRC requires disclosure of any person with significant control or influence over the trust |
How to register, claim and manage your trust on the TRS
We guide you through the online steps so the process feels straightforward and your trust records stay secure and up to date.
Setting up Government Gateway access as an organisation
Create a Government Gateway organisation account — this is necessary because the trustees act collectively on behalf of the trust. It is important to understand that a trust is a legal arrangement, not a separate legal entity with its own legal personality. The trustees are the legal owners of the trust property and act in that capacity, which is why the Government Gateway account is set up as an “organisation” representing the body of trustees. Keep your Gateway ID, password and chosen security method safe and accessible to the lead trustee.
Only the lead trustee — or their appointed agent — can claim the TRS record. If you use an agent to act on behalf of the trustees, you must provide clear written authority for them to do so.
Submitting registration and obtaining a UTR or URN
Complete the online registration form on the Trust Registration Service. Once HMRC processes the submission, they will issue either a URN (for non-taxable trusts) or a UTR (for taxable trusts). For taxable trusts, HMRC posts a letter containing the UTR to the lead trustee’s correspondence address. Non-taxable registrations typically receive their URN more quickly through the online system.
Claiming, safekeeping and avoiding lockouts
Claiming links the registered TRS record to the lead trustee’s Government Gateway account, giving them ongoing access to update and manage the trust’s details. When claiming, you must match your personal details exactly to those held by HMRC — any discrepancy in name spellings, dates of birth or addresses will block the process.
Three incorrect login attempts can trigger a 30‑minute lockout. Keep your URN or UTR in a secure location and share a copy with your solicitor or agent to avoid delays in future trust administration.
- Tip: Store your URN/UTR with your trust deed and other estate planning documents in a secure but accessible location.
- Tip: Present your TRS registration evidence (including the URN or UTR) when dealing with banks and financial providers — this significantly reduces hold-ups on transactions.

How to stay compliant after registration
A few simple habits will keep you compliant and avoid unnecessary penalties. Make a yearly plan and diary key dates so the burden does not fall on a single trustee at short notice. Registration is not a one-off event — the TRS is a living record that must be kept up to date for the life of the trust, which can last up to 125 years under current English and Welsh law.
Reporting changes within 90 days
Any material change — new trustee appointments, trustee resignations, beneficiary additions, changes of address or contact details, or significant changes to the trust assets — must be updated on the TRS within 90 days of the event. The same 90-day rule applies when a new trust is created and first becomes registerable.
Annual review and declaration for taxable trusts
Taxable trusts require an annual review and declaration. Even if nothing has changed during the year, the trustees must make a formal annual declaration confirming that the TRS details remain correct, usually by 31 January following the end of the tax year. Failing to submit this declaration can result in a penalty — even if no tax is actually owed.
How TRS updates link to the SA900 trust tax return
The TRS record and the trust and estate tax return (SA900) must be kept consistent. Where the trust is liable to income tax or capital gains tax, the trustees must file the SA900 and ensure the TRS record is up to date when completing the return. Discrepancies between the two — for example, different trustee names or different asset descriptions — can trigger HMRC enquiries and delay the processing of the return.
Deliberate failure to keep TRS details updated can result in penalties of up to £5,000 per trustee, plus potential anti-money laundering consequences.
| Action | Deadline | Who acts |
|---|---|---|
| New trustee appointment | Within 90 days of the appointment | Lead trustee or appointed agent |
| Beneficiary change | Within 90 days of the change | Trustees (jointly responsible) |
| Annual declaration (taxable trusts) | By 31 January following the end of the tax year | Trustees or appointed agent |
Practical tip: Keep one secure folder — physical or digital — containing your URN/UTR, a copy of the trust deed, the names and contact details of all current trustees, and a note of key diary dates for annual declarations and potential 10-year periodic charges. For discretionary trusts subject to the relevant property regime, the maximum 10-year periodic charge is 6% of trust property above the nil rate band (currently £325,000) — for most family homes held in trust, this works out at zero or very little. That single folder saves time and significantly reduces the risk of missed deadlines.
Conclusion
A few simple steps now can save your family significant time and trouble later.
Most UK express trusts — and many overseas trusts with a UK connection — are now within scope of the TRS. It pays to check whether your trust needs registration rather than assume the older, narrower rules still apply.
The process is straightforward: identify whether you must register, gather your trust deed and identity details for all relevant parties, choose a lead trustee, then complete the online registration so you can prove the trust’s status to banks and financial providers when they ask.
Keep your URN or UTR safe and accessible. That reference number speeds up dealings with HMRC, banks, solicitors and investment providers — and avoids holds on trust assets when your family most needs access. Trust assets bypass probate entirely, meaning trustees can act immediately on the settlor’s death without waiting for a Grant of Probate — but only if the TRS record is up to date and the reference number is to hand.
Non-compliance can trigger an initial penalty of £100, escalating for continued or deliberate failure, with potential anti‑money‑laundering consequences on top. Small annual checks and a 90-day diary habit prevent much bigger problems down the line.
If you are unsure whether your trust is in scope, speak to a solicitor who specialises in trust law or an experienced agent who handles trust registration — getting it right first time is far easier than correcting errors later. As Mike Pugh often says, “Plan, don’t panic.” At MP Estate Planning, we handle TRS registration as part of our trust setup process, so our clients’ trusts are compliant from the moment they are created.
