How to Register a Trust With HMRC: Step-by-Step Guide

register trust with hmrc

We’ll walk you through the essentials. Most UK trusts must be listed on the Trust Registration Service (TRS). That means trustees need to give accurate details online and keep them up to date.

There is no fee to use the TRS. The process protects family assets and helps avoid delays or penalties when dealing with tax or property matters.

We explain how to decide if your trusts need registration, how to gather the right information, and how to submit details on the TRS. We also cover what happens after submission, such as receiving a URN or UTR and why you should store those safely.

Our aim is to make this simple. We write in plain language, offer real-life priorities for homeowners, and point to practical steps. If you want extra help, an agent or adviser can assist you.

Key Takeaways

  • Most trusts must use the TRS and trustees usually handle registration.
  • TRS is free; you only need accurate information and key details.
  • After submission you receive a URN or UTR — keep these safe.
  • Registering helps protect assets and avoids unnecessary penalties.
  • You can choose professional help if the process feels complex.

What the Trust Registration Service is and why it matters

Think of the trust registration service as the central record where TRS lists who runs a trust and what it holds. The online system keeps a clear trust register so decisions about assets are easier and faster.

The middle ground includes a large whiteboard with flowcharts outlining steps of trust registration. The background shows an office with large windows allowing natural sunlight to flood in, reflecting a bright and inviting atmosphere. The scene is captured from a slightly elevated angle, enhancing the sense of collaboration and seriousness. Warm lighting adds a professional yet welcoming feel, emphasizing the importance of trust registration in a business context.

How TRS supports compliance and protects beneficiaries

TRS helps meet anti‑money laundering rules and keeps a public‑sector record that safeguards beneficiaries. That clarity reduces disputes and speeds up dealings over property or tax.

“Keeping accurate details prevents delays and protects those who benefit.”

Key roles: settlor, trustees, beneficiaries and the lead trustee

A settlor puts assets into the arrangement. Trustees manage assets day to day. Beneficiaries receive benefit under the settlement.

The lead trustee is the main contact for TRS and usually updates the online record. Mistakes often happen when dates, beneficiary details or trustee contacts are wrong. Solicitors or accountants can act as agents, but trustees remain responsible for accurate information and prompt registration.

  • Keep records short and accurate.
  • Check names, dates and contact details before you submit.
  • Use a professional if you are unsure, but stay in charge.

Do you need to register your trust with HMRC?

The simplest rule of thumb: most express settlements in the UK now need a TRS entry.

Express trust means the settlor created it on purpose, usually by deed or will. Many such trusts must be listed even if there is no immediate tax charge.

Since September 2021, many non-taxable trusts also fall under the rule. In practice this means a family arrangement holding assets can still need registered status despite no Income Tax, Capital Gains Tax or IHT now.

The middle ground features a laptop displaying financial graphs, symbolizing careful financial planning. In the background, a well-organized bookshelf filled with legal textbooks and binders conveys a sense of expertise and professionalism. Soft, natural light filters through a nearby window, creating an inviting and focused atmosphere. The entire scene evokes trust, responsibility, and diligence, emphasizing the importance of properly registering a trust for financial clarity and compliance.

Common exemptions exist. Examples include some will-based trusts kept only for up to two years after death and certain charitable arrangements. Non-UK settlements may also need a record if they hold UK property, receive UK income or have UK business relationships.

  • Check how the arrangement was created — deed or will wording usually signals an express trust.
  • If unsure, ask a solicitor or tax adviser — trustees remain responsible for accuracy.
  • For agent help, see our guide on acting as an agent.

Deadlines, timing and penalties for late registration

Timing matters: knowing when the 90‑day clock starts can save trustees from penalties.

The 90‑day window usually runs from the day the trust is created or the day it stops being excluded. For non‑taxable arrangements created after 6 October 2020, action is required within 90 days.

There is also an historic cutoff: non‑taxable trusts created on or before 6 October 2020 should have been listed by 1 September 2022. That date still matters if you are checking older records.

What happens if the deadline is missed

HMRC can follow up with compliance checks and requests for information. Delays can look like inaction even if nothing obvious has occurred.

If officials judge the failure deliberate, a fixed penalty may follow. Fines can reach £5,000 depending on the case.

Practical checklist for trustees

  • Note the date the trust was created.
  • Confirm whether it is taxable or excluded.
  • Diarise the 90‑day deadline and any historic dates.
  • Keep information and details accurate — late updates risk exposure too.

Information you need before you start the trust registration

Before you begin the online form, gather the key facts so one sitting is enough to finish the process. This saves time and lowers the risk of mistakes.

Core trust details HMRC asks for

Have the formal name, the exact date the arrangement was created and the trust type ready. These three items determine how the record is set up and what follow‑up is needed.

Assets and property to note

List assets held, including UK land, any home and investments. Be clear about ownership: whether the asset is fully held, mortgaged or jointly owned.

Soft natural lighting filters in through a window, casting gentle shadows, creating a focused and professional atmosphere. The overall mood is one of responsibility and clarity, reinforcing the importance of accurate record-keeping in financial matters.

Personal details for people involved

Provide full names, dates of birth, contact details and country of residence for trustees, the settlor and beneficiaries. Matching spellings and dates matters for later checks.

Lead trustee essentials and taxable trusts

The lead trustee needs a National Insurance number and a reliable contact email or phone. For taxable trusts, have extra tax identifiers and account details ready so the record links to ongoing reporting.

Practical tip: keep a secure paper and digital file of the final details. For a broader look at benefits, see our short guide on unlock the benefits of a UK.

How to set up a Government Gateway account for trust registration

Before you begin the TRS form, set up a Government Gateway account correctly. This is the first practical step and it stops later delays.

Soft, diffused lighting creates a calm and productive mood, while the camera angle is slightly above eye level for a dynamic perspective. The overall composition emphasizes clarity, professionalism, and the digital aspect of government registration processes.

Why use an organisation account, not a personal one

For TRS access you must choose an organisation government gateway account. You are acting on a trust’s behalf, so the service expects an account that represents an organisation rather than a private person.

This keeps the record professional and avoids identity checks failing because personal details do not match the trust’s details.

Security codes, login details and keeping access safe for trustees

During setup you receive a time‑limited email access code and a Government Gateway ID. You may also get security codes by text or phone. Have the lead trustee’s email and mobile ready before you start.

Store the gateway account ID, password and recovery details in a secure place. Treat them as part of the trust’s core records so changes in trustees do not cause lockouts.

  • Set up an organisation government gateway account using the lead trustee’s contact details.
  • Keep the email and phone used for codes active and accessible to authorised persons.
  • Avoid mixing personal accounts and organisation accounts to prevent identity checks failing.

How to register trust with HMRC using the TRS

We guide you through the online TRS journey so you can complete the application confidently.

The composition is vibrant yet professional, capturing the essence of trust management.

Starting the TRS application and choosing the right category

Begin by logging into your organisation Government Gateway account and opening the TRS. Select the correct category: express, discretionary, life interest or other types that match the settlement.

Tip: choose taxable or non‑taxable correctly. That choice affects subsequent questions and whether a UTR will follow.

Entering trustees, settlor and beneficiary details accurately

Enter every trustee’s full name, date of birth, nationality and contact details. Add the settlor and any beneficiaries, matching spellings to supporting documents.

A small error here causes delays later. Double‑check names, dates and addresses before you progress.

Adding trust assets and confirming UK property information

List key assets and show values where requested. For UK property, give the full address and clarify ownership share or mortgage status.

Trust assets often include the family home. Make this clear so future dealings run smoothly.

Submitting the declaration and what happens immediately after submission

When you submit, the lead trustee confirms the details are true. The system shows an online confirmation and a reference screen.

HMRC may follow up by post or email if they need further information. Keep records of the submission screen and any confirmations.

What you receive from HMRC and expected timescales

After successful registration you receive either a URN for non‑taxable arrangements or a UTR for taxable ones.

For taxable trusts, expect a UTR to arrive typically within 15 working days. Hold these references safely — they are needed for future filings and claims.

StepWhat to enterWhy it matters
Choose categoryTrust type and taxable statusDetermines form path and identifiers issued
PeopleTrustees, settlor, beneficiaries detailsMust match documents to avoid checks
AssetsList trust assets and UK property detailsEnsures correct valuation and future claims
DeclarationLead trustee confirms accuracyTriggers confirmation and HMRC processing

After registration: claim, maintain, update and close the trust record

A registered entry still needs an active claimant: only the lead trustee can claim and manage it on the TRS. Claiming links the record to a lead contact so updates and filings can be made.

How the lead trustee claims a registered record

The lead trustee must use the URN or UTR and complete identity checks in the account. Details must match the original entry exactly to avoid delays.

Keeping details up to date

Trustees must update TRS within 90 days of changes. That includes adding a new trustee, changing addresses or altering beneficiary information.

Annual duties for taxable arrangements

Taxable trusts need a declaration by 31 January each year to confirm information is correct. If the trust has income or gains, an SA900 may be required.

Using an agent and closing the record

An authorised agent can act on behalf of the lead trustee. Even so, trustees remain responsible for accuracy.

When assets are fully distributed, the lead trustee should close the entry and save the final declaration and closure date for records.

“Keep the lead trustee’s contact details and references safe — they unlock control and future filings.”

Conclusion

Final checklist: confirm whether you must enter a settlement on the TRS, gather the correct information, set up an organisation account, complete the online form and store the URN or UTR securely.

Keep the record current. Update details within 90 days of any change. Meet annual declarations where tax applies to avoid penalties.

If anything feels unclear — especially about exemptions, non‑UK links or taxable reporting — consider professional services or an authorised agent to reduce mistakes.

We aim to make this manageable. With a clear plan and good records, most families can register and manage trusts confidently and protect beneficiaries for the long term.

FAQ

What is the Trust Registration Service and why does it matter?

The Trust Registration Service (TRS) is a government digital service for recording details about certain trusts. It helps ensure compliance with tax rules and protects beneficiaries by keeping clear records of who controls and benefits from assets. Using the service means trustees meet legal duties and make it easier to resolve tax or inheritance questions.

How does TRS support compliance and protect beneficiaries?

TRS keeps a central record of a trust’s key facts, such as trustees, settlors and beneficiaries. That transparency reduces fraud, helps HM Revenue & Customs check tax liabilities, and makes it simpler for families to prove entitlement. It also provides an official reference when dealing with banks or solicitors.

Who are the key roles in a trust and what do they do?

The main people are the settlor who creates the arrangement, trustees who manage the assets, and beneficiaries who receive benefit. One trustee usually acts as lead trustee and handles dealings with the service. Each role has clear responsibilities to protect assets and meet reporting duties.

Which arrangements normally need to be listed on the TRS?

Most UK express arrangements where assets are held for beneficiaries must be recorded. This includes many lifetime and will trusts, as well as those that receive UK income or gains. Taxable arrangements always need attention; non-taxable arrangements may still require details if created after 2021.

Do non-taxable arrangements created after 2021 have to be recorded?

Yes. New rules mean many non-taxable arrangements created since 2021 must be entered onto the TRS. If you’re unsure, check whether the arrangement meets the criteria for having identifiable beneficiaries or UK connections.

What common exemptions are there from the TRS requirement?

Certain will trusts that only come into effect on death, some small family arrangements, and many charitable structures can be exempt. Specific exclusions apply, so trustees should review the guidance or seek advice before assuming an exemption.

Do non-UK arrangements with UK connections need to be recorded?

If an arrangement has UK elements — such as UK assets, trustees in the UK or beneficiaries resident here — it may fall under the service rules. Cross‑border situations often need specialist advice to establish reporting responsibilities.

When must trustees complete the TRS entry after creating a taxable arrangement?

Trustees usually have 90 days from the date the arrangement becomes chargeable to provide the required information. Acting promptly avoids late penalties and simplifies future tax reporting.

What might happen if trustees miss the 90‑day period?

HM Revenue & Customs can charge penalties, issue compliance notices and, in serious cases, open enquiries. Early action and contact with HMRC can often reduce penalties, so trustees should not delay.

What penalties should trustees be aware of?

Penalties can vary with the nature and duration of the delay. Fixed fines and escalated charges are possible, with significant maximums for serious or persistent failures. Clear records and timely updates help avoid these costs.

What trust details are needed before starting an entry on the TRS?

You’ll need the arrangement’s name, date it was created, and the type of arrangement. Also prepare details of assets such as UK land and investments, plus the roles and personal information for trustees, settlors and beneficiaries.

What asset and property information should be ready?

Provide values and descriptions of assets held, including UK property, bank accounts and investments. HMRC asks for precise details about locations and the nature of the holdings to determine tax connections.

What personal details are required for trustees, settlors and beneficiaries?

HMRC typically asks for full names, dates of birth, nationalities, addresses and sometimes National Insurance numbers for UK residents. Accurate details help avoid future queries and make claims by the lead trustee straightforward.

What does the lead trustee need to provide?

The lead trustee should supply contact information and, where applicable, a National Insurance number. They act as the primary point of contact for HMRC and must keep other trustees informed of any changes.

Do taxable arrangements need extra information?

Yes. Taxable arrangements require additional details about income, gains and tax liabilities. Trustees should keep records of income and transactions to support annual declarations and any returns.

How do we set up a Government Gateway account for use with the TRS?

You set up a Government Gateway account online and choose an organisation account if acting on behalf of a trust. This account gives secure access to TRS and other services and must be managed carefully to protect sensitive data.

Why use an organisation account rather than a personal one?

An organisation account allows multiple authorised users to act on behalf of the arrangement and meets HMRC access requirements. It separates personal details from trust administration and improves security.

How should trustees keep login details and security codes safe?

Use strong, unique passwords and store security codes in a secure place. Limit access to authorised trustees and change credentials promptly if someone leaves. Regularly review access to reduce the risk of unauthorised changes.

How do we begin the TRS application and choose the right category?

Start by selecting the trust type that best matches your arrangement — for example, discretionary, bare beneficiary or life interest. Accurate categorisation matters because it determines which information HMRC requires.

How should trustees enter details of trustees, settlors and beneficiaries?

Enter all names and required personal data exactly as shown on official documents. If beneficiaries are unnamed classes, use the category descriptions and provide as much detail as possible to reflect the arrangement’s intentions.

What about adding assets and confirming UK property information?

List each asset clearly, stating location and value. For UK property, include addresses and any title details. This information helps HMRC judge tax status and ensures the record is complete.

What happens immediately after submission of the TRS entry?

After you confirm the declaration, HMRC processes the details and issues identifiers. Keep a copy of the confirmation and the unique reference number for future correspondence.

What references do we receive from HMRC after submitting details?

For non-taxable arrangements you receive a Unique Reference Number (URN). For taxable arrangements HMRC issues a Unique Taxpayer Reference (UTR). Keep these safe; they allow the lead trustee to claim and manage the record.

How long does it take to receive a UTR for taxable arrangements?

HMRC usually issues a UTR within about 15 working days, though it can vary. If you haven’t heard after a reasonable period, contact HMRC to check the status.

How does the lead trustee claim an arrangement on the TRS using a URN or UTR?

The lead trustee logs into the service, selects the option to claim an existing record, and enters the URN or UTR. This links the organisation account to the arrangement so the trustee can manage and update details.

When must details be updated on the TRS after changes occur?

Trustees must update most changes within 90 days. This includes changes to trustees, beneficiaries, addresses or assets. Timely updates ensure accuracy and reduce the risk of penalties.

What annual responsibilities do trustees of taxable arrangements have?

Taxable arrangements usually require an annual declaration by 31 January and the reporting of income and gains. Trustees may also need to complete specific tax returns such as the SA900 where applicable.

How do trustees report arrangement income and gains?

Trustees report taxable income and gains through the appropriate HMRC channels and include details on the annual declaration. Keeping clear records throughout the year makes this process straightforward.

How can an arrangement be closed on the TRS once assets are distributed?

Once the assets are fully distributed and obligations are met, the lead trustee can apply to deregister the record via the service. Provide final details of distributions and the date the arrangement ended.
