Quick answer
HMRC trust penalties in England and Wales typically stem from failures to register with the Trust Registration Service (TRS) or file required information, with fixed penalties of £5,000 commonly applied for missed deadlines. Most UK trusts must register if they hold assets or generate income, though some exceptions apply—notably trusts with capital under £1,000 and certain bare trusts. Since the TRS launched in 2017, trustees face penalties for late registration, failure to update relevant information, or non-compliance with anti-money-laundering checks. Penalties may increase if breaches persist, and HMRC can pursue further action. The good news is that most penalties are avoidable through timely registration, accurate record-keeping, and prompt responses to HMRC correspondence. This guide explains how HMRC trust penalties work in 2026/27, practical steps to prevent them, and how to resolve penalties if they’ve already been issued.
Last reviewed: 24 May 2026 by the MP Estate Planning editorial team. Jurisdiction: England and Wales. Scotland and Northern Ireland have different probate and intestacy rules; the IHT thresholds are UK-wide.
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.”
We help trustees protect family assets without legalese. Since 2017 the Trust Registration Service (TRS) has made registration and reporting part of life for most UK trusts. The TRS supports tax reporting and anti‑money‑laundering checks, and a missed duty can lead to a fixed £5,000 penalty in some cases.
We will explain what these charges are, why they happen, and how trustees can avoid an expensive surprise. Our aim is practical and friendly. Many people become trustees through family duty, not training, so our guidance stays simple.
Good compliance means knowing if a trust must register, gathering the right details, and keeping records up to date. Penalties usually stem from missed deadlines, late updates, or ignoring correspondence. If you already have a problem, we set out clear next steps and how to challenge a charge where it feels unfair.

Trust Registration Service requirements trustees must meet
Most family arrangements need checking for registration — it’s easier than it sounds. We set out what the register is, who must sign up and the dates you should diarise.
What the registration service is and why it exists
The trust registration service is an online register run to improve tax transparency and support anti-money‑laundering checks. It helps authorities spot where a tax charge may arise and where further checks are needed.
Which arrangements must register
The vast majority of UK arrangements and settlements are affected. Taxable cases always need recording. Since 2020 (5MLD) many non-taxable trusts also fall within scope unless specifically excluded.
Key deadlines and time limits
Registration generally had to happen within 90 days of creation for new arrangements. Older cases were expected to be on the register by 1 September 2022. Taxable entries need an annual confirmation by 31 January and all changes updated within 90 days.
| Type | Must register? | Key deadline | Ongoing duty |
|---|---|---|---|
| Taxable | Yes | Within 90 days | Annual return by 31 January |
| Non-taxable (most) | Often | Within 90 days or by 1 September 2022 | Update changes within 90 days |
| Excluded (Schedule 3A) | No | N/A | Keep records to show exclusion |
If you’re unsure whether an arrangement must register, use our practical registering guide to check dates and the exact requirement. We recommend diarising the relevant date and updating details within days of any change.
How to prevent hmrc trust penalties through timely trust registration and updates
Start by checking whether your arrangement must be on the register or is safely excluded — that single check saves time and worry.
Check whether your trust is excluded or must register
Confirm eligibility first. This avoids wasted effort and reduces the risk of a failure register issue.
Gather the trust details the TRS expects
Collect the names, dates, addresses, tax references and asset summary in one place. Having full details avoids repeated stops in the registration process.
Set up access using an Organisation Government Gateway ID
Use an Organisation ID, not an Individual ID. In practice you may need a separate Organisation ID for each trust you manage.
Register a trust on the online portal and record the submission date
Complete the online registration, save a PDF copy and note the submission date. That date matters if a question arises later.
Keep TRS information accurate by updating changes within 90 days
Any change of trustee, beneficiary, assets or address should trigger an update within 90 days. For taxable trusts, plan the annual confirmation by 31 January each year.
Avoid common non-compliance triggers
“Act quickly on changes and keep one clear file — it stops most nudge letters.”
Common causes of a compliance letter include long gaps since creation, missing updates after a change and inconsistencies with tax filings. Make TRS maintenance a simple household routine and you will reduce risk.
How HMRC applies trust penalties and what to do if you receive a penalty notice
A posted penalty starts a strict timetable — knowing each step protects you and other trustees.
What counts as an offence
We treat an offence as one of three things: failing to register when required, registering late, or not updating service details after a change.
How the fixed £5,000 charge can arise
The charge can be £5,000 per offence. Decisions are taken on a case‑by‑case basis, so repeated failures risk multiple fines.
When a charge may not be imposed
If the failure was not deliberate and you correct the details within the time limit set, a charge may not be applied.
Immediate steps when a notice arrives
- Confirm exactly what the notice says is missing.
- Update the online service and save proof of the change.
- Keep dated evidence and tell co‑trustees straight away.
Challenge and payment routes
Request a review within 30 days with supporting information. HMRC usually replies in about 45 days and the penalty is not payable during a review. If needed, appeal to the independent tribunal within 30 days.
“Act quickly, correct the record and keep evidence — that often resolves the case.”
Practical payment options include Faster Payments, BACS/CHAPS, Direct Debit, card or cheque. Trustees are personally liable, so keep proof of settlement for your records.
Conclusion
Small acts now — register, update, diarise — stop small problems becoming major ones.
Most family trusts need attention under the registration service. The simple message is clear: register on time, update within 90 days of any change, and diarise the 31 January annual declaration for taxable cases.
Keep TRS details accurate and break the process into steps. Treat the register like a home safety check: verify who is named, record the facts, and update them when things change.
We recommend our step‑by‑step guide to registering a trust if you need a calm, practical route through the registration service. Act now to protect the people the arrangement was set up to help.
FAQ
What is the Trust Registration Service and why does it exist?
The Trust Registration Service is an online register set up to record details of many UK arrangements that hold assets for others. It helps ensure transparency for tax and anti-money‑laundering purposes. We recommend registering early so the correct records exist for inheritance tax and other liabilities.
Which UK arrangements must register, including taxable and non‑taxable ones?
Many settlements need registration. Taxable arrangements — those with a liability for income tax, capital gains tax or inheritance tax — must register. Some non‑taxable arrangements also need listing when they have UK tax implications or specified features. We can check your situation if you are unsure whether your arrangement is excluded.
What are the key deadlines, including the 90‑day rule and the September 2022 cut‑off?
If an arrangement becomes registrable, details should be submitted within 90 days of the event that creates the requirement. There was a notable compliance date in September 2022 affecting some earlier non‑taxable arrangements; those required review and possible late registration. Missing deadlines increases the risk of enforcement action.
How do we check whether our arrangement is excluded or must register?
Start by confirming the type of arrangement and any tax liabilities it has. Simple family trusts for estate planning may still need to register. We run through key questions with trustees — assets, beneficiaries and tax position — to give a clear answer.
What details are needed when gathering information for registration?
You will need the arrangement’s name, start date, settlor or settlors, trustees’ details, beneficiaries or class descriptions, any protectors, and the assets held. We also collect tax‑related information and documents to support the entries.
How do we set up correct access using an Organisation Government Gateway ID?
Access is usually via an Organisation Government Gateway ID or an existing agent authorisation. One trustee should set up the organisation ID and assign the service to the person registering. We can guide you through creating the ID and linking the right users to avoid access delays.
How do we register an arrangement on the online portal and record the submission date?
Use the online portal to complete the registration form and upload supporting details. When you submit, note the confirmation reference and the submission date. Keep a screenshot or download the acknowledgment for your records — it proves timely compliance.
How should we keep registration information accurate and update changes within 90 days?
Any significant change — trustee appointments, beneficiary changes, or changes to asset location — should be updated within 90 days. Assign someone to receive correspondence and set calendar reminders so updates are made promptly.
What ongoing duties apply for taxable arrangements, including the 31 January annual declaration?
Taxable arrangements must complete an annual declaration by 31 January each year where required. This confirms whether liability remains. Trustees must also keep records and supply further information if asked.
What common triggers lead to compliance notices and enforcement?
Late registrations, missing updates, incomplete details and ignoring reminder letters are frequent triggers. Failure after a nudge letter raises the chance of a fixed penalty or further action. Staying organised prevents most issues.
What counts as an offence and how can a fixed penalty arise?
An offence generally occurs when required information is not provided, is false or is not updated within allowed time limits. A fixed penalty — often a set sum — can be issued where trustees fail to comply and no reasonable excuse is accepted.
When might a penalty not be charged, such as for non‑deliberate failures?
If a failure is not deliberate and trustees correct the mistake promptly, enforcement may be waived. HM Revenue & Customs may accept reasonable excuses like serious illness or postal issues. Keep evidence and act quickly to mitigate risk.
How should we respond to a posted penalty notice and what action should we prioritise?
Read the notice immediately, confirm whether the facts are correct, and correct any missing information right away. If you dispute the notice, follow the review process within the stated time. If the details are right, arrange payment or seek advice about mitigation.
What challenge routes exist, including requesting an HMRC review within 30 days?
You can ask for an internal review if you disagree with a penalty. That request typically must be made within 30 days. Provide supporting documents and a clear explanation. If unsatisfied, you can appeal to the tax tribunal within the allowed time frame.
How does an appeal to the tax tribunal work and what happens during the appeal window?
An appeal is a formal request for judicial review. During the window, you submit grounds and evidence. Proceedings can include written submissions and a hearing. Outcomes range from cancellation to reduction of the charge. Legal or specialist advice helps.
What practical points should trustees know about paying a penalty and personal liability?
Trustees are responsible for meeting liabilities linked to their duties. Some penalties can become the personal responsibility of individual trustees if the arrangement’s funds are insufficient. Keep records, seek professional help and prioritise resolving issues to limit personal exposure.
What happens if a trust is not registered — and which trusts are exempt
Consequences beyond the penalty charge itself
The £5,000 fixed penalty cap under Schedule 55 of the Finance Act 2009 is the figure most trustees focus on, but in our experience the downstream consequences of non-registration can be considerably more disruptive than the charge itself. A trust that has not been registered on the Trust Registration Service (TRS) will not hold a valid Unique Reference Number, which means trustees may be unable to demonstrate compliance to banks, conveyancers, or other obliged entities when those third parties carry out their own anti-money laundering checks. This can, in practice, delay or block property transactions, bank account openings, and the administration of a deceased settlor’s estate at probate.
There is also an inheritance tax dimension that government guidance does not make explicit. Where a trust holds property and the trust has not been registered, HMRC may scrutinise the wider IHT position of the estate more closely on a related grant of probate or on a ten-year anniversary charge. Non-registration does not in itself create an IHT liability, but it can trigger a fuller enquiry at a time when trustees are already under pressure. Trustees should also be aware that obliged entities — solicitors, accountants, estate agents — are required under the Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2017 to collect and verify TRS registration information before providing certain services. A missing registration therefore places a practical burden on professional advisers as well as on the trustees themselves.
Which trusts are exempt — a practical self-test against Schedule 3A exclusions
Not every arrangement that uses the word “trust” must register. Schedule 3A of the Money Laundering Regulations 2017 sets out the exclusions, and a number of them are genuinely broad. Trusts that are typically excluded include: statutory trusts arising on intestacy; trusts used solely to hold a single life insurance policy or retirement policy and that pay out only on death, terminal illness, or disability; co-ownership arrangements over a jointly owned property where the legal and beneficial owners are identical; trusts that are already registered with HMRC in another capacity (for example, a registered pension scheme); and certain charitable trusts registered with the Charity Commission.
In practice, the most common self-test question our team encounters is whether a bare trust holding a child’s savings account needs to register. In most cases, if the arrangement was created solely to hold a cash deposit and there is no written trust instrument, it will fall outside the scope of a registrable express trust — but trustees should take qualified legal advice before relying on that exclusion, because the facts matter considerably. Trusts that hold UK land, trusts with UK tax consequences, and discretionary family trusts will generally need to register regardless of whether they have been formally documented by deed.
Trustees of non-taxable trusts that were in existence before 6 October 2020 should note that the extended registration deadline was 1 September 2022. That date has passed, and any trust that missed it may already be in a position of retrospective non-compliance. HMRC’s published guidance suggests that it may exercise discretion over penalties where there is a reasonable excuse and the failure is corrected promptly, but there is no guarantee that discretion will be applied in every case.
Declaration of trust versus trust deed — the legal distinction for property-holding arrangements
A declaration of trust and a trust deed are both instruments that create or evidence a trust, but they serve different functions and the distinction matters for registration and Land Registry purposes. A declaration of trust is typically a unilateral statement by a person who holds property confirming the terms on which they hold it — most commonly used where co-owners of a property wish to record their respective beneficial shares. A trust deed, by contrast, is generally a bilateral document executed between a settlor and one or more trustees, transferring assets into trust and setting out the administrative and beneficial provisions.
For property-holding arrangements in England and Wales, a declaration of trust that alters beneficial ownership is generally not registrable at HM Land Registry as a matter of course — the legal title need not change. However, if the declaration creates a trust that otherwise meets the TRS registration criteria (for example, because it is an express trust holding UK land), registration on the TRS will still be required. The two registration systems operate independently, and satisfying one does not satisfy the other. Trustees who hold property under any form of written arrangement should take professional advice to confirm whether both obligations apply to their specific circumstances.
Common questions about HMRC trust registration and penalties
What trusts are exempt from HMRC registration?
A number of trust arrangements fall outside the TRS registration requirement under the Schedule 3A exclusions to the Money Laundering Regulations 2017. These typically include trusts holding a single life or protection policy, statutory trusts arising on intestacy, bare co-ownership arrangements where legal and beneficial title align, and trusts already registered with the Charity Commission or as a registered pension scheme. The exclusions are fact-specific, and trustees should not assume an arrangement is exempt without checking the precise terms of the instrument against the published exclusions. HMRC’s own guidance on types of trust provides a useful starting point, but it does not substitute for advice on a specific arrangement.
What happens if a trust is not registered?
If a registrable trust is not registered, the trustees risk a penalty of up to £5,000 per offence under Schedule 55 of the Finance Act 2009 — though this is a maximum, not an automatic charge. HMRC may exercise discretion where there is a reasonable excuse and the breach is remedied quickly. Beyond the penalty, unregistered trusts may find that obliged entities such as solicitors and banks are unable to act for them without a valid TRS Unique Reference Number, which can materially delay property transactions and estate administration. There may also be heightened HMRC scrutiny of connected inheritance tax returns.
What is the difference between a trust deed and a declaration of trust?
A trust deed is generally a document executed between a settlor and trustees to transfer assets into a new trust and govern its operation. A declaration of trust is typically a statement by a current legal owner confirming the basis on which they hold an asset for another — most often used for co-owned property where the beneficial shares need to be recorded. Both can create binding trust arrangements, but the appropriate instrument depends on the nature of the asset and the relationship between the parties. Either may trigger TRS registration obligations if the underlying arrangement meets the registration criteria.
What happens with a declaration of trust?
Once executed, a declaration of trust is legally binding and evidences the beneficial ownership of the asset in question. For a property, this means the stated shares will generally govern how sale proceeds or rental income are divided, and HMRC may refer to it when assessing capital gains tax or income tax. If the declaration creates an express trust over UK land, registration on the TRS is likely to be required within 90 days of the trust coming into existence — or, where a registrable change occurs such as a change in the beneficiary class or the death of a trustee, within 90 days of that event. Failure to update the TRS within that window is itself a potential source of non-compliance, separate from the original registration obligation.
What is the difference between a trust and a declaration of trust?
A trust is the legal arrangement itself — the relationship under which one person holds an asset for the benefit of another. A declaration of trust is the written instrument that creates or evidences a particular type of trust, usually where the legal owner is also confirming they hold property for others. Not every trust will be recorded in a declaration; some arise by operation of law, by will, or by a formal deed. The distinction matters in practice because HMRC’s TRS registration requirement applies to express trusts — those deliberately created — and the form of the document used to create the trust does not change whether the registration obligation applies. Trustees who are uncertain about the status of any arrangement they administer should consider seeking qualified legal advice before concluding that registration is unnecessary.
