HMRC Mandated Income Rules for Trusts

hmrc mandated income trust rules

We explain, in plain terms, how the tax position shifts when trustees direct payments so they go straight to a beneficiary. This matters for who pays the tax and who files the Self Assessment.

We will walk through the key points: what counts as directed payments, how the trust deed wording and entitlement affect outcomes, and where problems often arise. Typical pinch points include bank interest, dividends and rental profits. Timing of payments also changes who reports and who pays tax.

Our aim is to set clear expectations. First identify the trust type and the deed wording. Then confirm whether payments are properly directed to the beneficiary. Finally, complete the right return or returns to avoid penalties and family disputes.

For extra help on life interest arrangements see our guidance on life interest trusts.

Key Takeaways

  • Directed (mandated) payments can move the tax liability from trustees to the beneficiary.
  • Check the trust deed and who is entitled before assuming who pays.
  • Watch bank interest, dividends and rental receipts for common issues.
  • Timing of payment affects Self Assessment obligations.
  • Clear records and prompt returns reduce disputes and penalties.

Understanding mandated income and why HMRC treats it differently

When trustees tell a payer to send money straight to a beneficiary, the path of payment changes. That change can alter who reports the amount for tax purposes and who must pay the tax.

Soft shadows enhance the depth, while a subtle glow from a desk lamp adds a calm ambiance. The overall mood conveys professionalism and trust, reflecting the importance of understanding mandated income in financial management.

What it means in practice

Mandating simply means instructing the payer — such as a bank, investment platform or tenant — to pay the trust’s receipts directly to the person entitled to them. This is most common in interest in possession arrangements where a life tenant has the right to the income as it arises. Because the beneficiary receives the income directly, HMRC treats it as theirs for tax purposes rather than the trustees’.

How reporting and liability change

  • Reporting: The beneficiary includes the mandated amounts on their own Self Assessment return.
  • Payment: The beneficiary pays tax at their own marginal rate, which may be lower than the trust rate of 45%.
  • Bank transfers: A trustee withdrawing cash from the trust account and paying it to the beneficiary is not the same as a valid mandate instruction to the payer. The distinction matters — only a genuine direction to the payer qualifies as mandated income.

Check your trust type first: the tax rules depend on the arrangement

Start by identifying what kind of trust arrangement you have — the tax outcome depends on that single fact. In English and Welsh trust law, the primary classification is how the trust operates: discretionary, bare or interest in possession. Remember, a trust is not a separate legal entity — it is a legal arrangement where the trustees hold legal ownership of the assets on behalf of the beneficiaries.

The atmosphere should be serious yet collaborative, reflecting the importance of understanding trust types and their tax implications. Use a slightly elevated angle to capture the entire scene, emphasizing teamwork and professionalism.

Interest in possession and life interest beneficiaries

An interest in possession trust gives one person — the life tenant — the right to the income from trust assets as it arises. Capital passes to a different beneficiary (the remainderman) when the life interest ends. In everyday terms, one family member receives regular income and another eventually inherits the capital. This is where mandating income is most relevant, because the life tenant has an immediate entitlement to receive income. Trustees of an interest in possession trust pay income tax at the basic rate (20% on non-dividend income, 8.75% on dividends) on behalf of the life tenant.

Accumulation and discretionary arrangements

With discretionary trusts, trustees decide whether to pay out or retain receipts — no beneficiary has a right to any income until trustees exercise their discretion. That usually leaves trustees facing the tax liability at the higher trust rates (45% on non-dividend income, 39.35% on dividends) and the filing duties. Mandating income is far less common with discretionary trusts because no beneficiary has an automatic entitlement. Discretionary trusts are by far the most common trust arrangement in England and Wales, making up the vast majority of family trusts.

Bare trusts and settlor-interested cases

A bare trust treats the beneficiary as the outright owner for tax purposes. The beneficiary reports receipts on their own Self Assessment and can use their personal allowances, personal savings allowance and dividend allowance. The trustee is simply a nominee holding legal title. Under the principle in Saunders v Vautier, a beneficiary of a bare trust who has reached 18 (16 in Scotland) can demand the assets be transferred to them outright at any time. This means bare trusts offer no meaningful asset protection — they cannot protect against care fees, divorce or beneficiary mismanagement.

Settlor-interested arrangements bring the settlor back into the picture under the settlements legislation. This can shift the tax liability to the settlor even if someone else receives the income — for example, where the settlor or their spouse can benefit from the trust. This is one reason why many family trusts are structured so that the settlor is expressly excluded from benefit.

  • Why it matters: the same £1,000 in one arrangement can be reported by trustees (discretionary), in another by the individual beneficiary (bare trust or mandated interest in possession), and in a third by the settlor (settlor-interested trust).

HMRC mandated income trust rules in practice for interest in possession trusts

When a life interest beneficiary receives payments straight from a payer under a valid mandate, the tax paperwork moves with the income.

Capture the scene with a slight depth of field, emphasizing the lawyer and documents while softly blurring the background, enhancing the focus on "interest in possession" trusts.

What changes when income goes directly to the income beneficiary

Where an interest in possession arrangement is in place and the payer has been instructed to send income directly to the life tenant, the beneficiary includes those amounts on their own Self Assessment. They pay tax at their personal marginal rate — which for many retired life tenants may be lower than the 20% basic rate that trustees would otherwise pay. This is one of the practical advantages of mandating: it can reduce the overall tax burden on the family.

What stays with the trustees even when income is mandated

The trustees still hold legal ownership of the trust assets. They must keep accounts, maintain records of the mandate instruction and be satisfied that the income is going to the person properly entitled under the trust deed.

Trustees may still need to: deal with other reporting obligations (such as capital gains), show records to HMRC to resolve queries, and remain responsible for any tax that has not been properly allocated to the beneficiary.

Common reporting outcomes when the beneficiary completes Self Assessment

  • The beneficiary reports the mandated income on their tax return and claims relevant allowances (including the personal savings allowance and dividend allowance where applicable).
  • If a payer reports income to the trust while the beneficiary also reports it personally, HMRC queries can follow — so co-ordination between trustees and the beneficiary is essential.
  • Quarterly distributions from investment managers need clear mandate evidence to avoid reporting mismatches.

Practical example: a distribution paid on 5 April can be treated in either tax year depending on when it is received. Clear dates and bank evidence stop mistakes and reduce the chance of queries or unexpected tax adjustments.

Income tax rates for trusts and the £1,000 standard rate band

We outline the practical effect of the standard rate band and the different rates that apply to dividend-type receipts and other trust income such as bank interest and rent.

A detailed office setting focused on income tax rates for trusts. In the foreground, a large wooden desk features neatly arranged financial documents and a calculator, symbolizing financial planning.

The atmosphere should be serious yet inviting, with a color palette of warm browns, soft greens, and hints of gold, evoking a sense of professionalism and trust. The angle is slightly elevated, providing a comprehensive view of the workspace without any text or distractions.

How the standard rate band works: discretionary and accumulation trusts receive a £1,000 standard rate band. The first £1,000 of income is taxed at the basic rate (20% for non-dividend income, 8.75% for dividends) rather than the higher trust rates. Income above £1,000 is taxed at the trust rate (45%) or dividend trust rate (39.35%). This band is not a tax-free allowance — it simply means the first slice is taxed at basic rate rather than the trust rate. Bare trusts are treated differently; the beneficiary is taxed as the owner using their own personal allowances and tax bands.

Trustees and the dividend allowance

Importantly, trustees do not get the personal dividend allowance that individuals enjoy (currently £500 for individuals). That means dividend-type receipts held by trustees of discretionary and accumulation trusts face trust rates from the first pound above the standard rate band. This is one reason mandating dividend income to a life tenant can be tax-efficient — the beneficiary can use their own dividend allowance.

Applicable rates at a glance

ArrangementDividend-type rateOther income rate (e.g. bank interest, rent)
Discretionary / accumulation (above £1,000 band)39.35%45%
Interest in possession (trustee element)8.75%20%

Multiple trusts and the £1,000 split

If a settlor has created several discretionary or accumulation trusts, the £1,000 standard rate band is divided equally between them. Where there are five or more such trusts, each receives a minimum of £200.

Quick tax year reminder: confirm which tax year receipts fall into. Timing affects the rates, the standard rate band allocation and who should report the tax liability. The UK tax year runs from 6 April to 5 April.

How trustees calculate taxable trust income and handle deductions

A neat breakdown of receipts into categories makes calculating taxable amounts much simpler for trustees.

We first split receipts into clear categories so each type gets the correct tax treatment.

In the foreground, a professional-looking middle-aged man wearing a suit diligently examines the paperwork.

Potted plants and bookshelves filled with legal texts can be seen in the background, suggesting a professional atmosphere. The overall mood conveys focus and precision, capturing the essence of trustees calculating taxable trust income and handling deductions in a serene yet productive environment.

Income types taxed differently

  • Bank/building society interest: taxed at 20% for interest in possession trustees and 45% (above the £1,000 standard rate band) for discretionary trustees. Received gross — no tax deducted at source since April 2016.
  • Dividends: carry the trustee dividend rate of 8.75% for IIP trusts and 39.35% for discretionary trusts (above the standard rate band). Also received gross — no tax credit since April 2016.
  • Rental profits from property: reduced by allowable property expenses (such as repairs, insurance and letting agent fees) before the net profit is taxed at the applicable trust rate.

Management expenses and deductions

Trust management expenses (TMEs) — such as professional trustee fees, accountancy costs and investment management charges — follow specific rules. They are set against income in a particular order: first against non-savings income, then savings income, then dividends. This order matters because it affects the tax pool available when trustees make distributions to beneficiaries.

Trustees should keep bank statements, platform reports and letting agent accounts. A simple allocation schedule helps reconcile different income streams into a single total for the SA900 trust and estate tax return.

  • Keep separate ledgers for interest, dividends and rent.
  • Note which expenses reduce rental profits (property expenses) and which are TMEs set against total trust income.
  • Use the “tax pool” to track how much tax credit is available when making distributions to beneficiaries.

Result: trustees can total taxable items accurately before deciding who reports or pays the tax, and ensure sufficient tax pool exists to cover beneficiary distributions.

How to complete reporting when income is not mandated

Where a payer sends receipts to the trustees rather than directly to a beneficiary, the default position is clear. The trustees must report the income, pay any income tax due and file the SA900 trust and estate tax return.

Trustees’ responsibilities

Trustees must file the SA900 trust and estate tax return. They calculate taxable amounts across each income category, settle the tax bill and keep clear records. Where income is later distributed to beneficiaries, trustees must track the tax pool to ensure they can account for tax already paid.

Providing beneficiary tax information

Trustees must issue R185 (Trust Income) statements so the beneficiary knows the gross amount of income they have received and what tax has already been deducted by the trustees. This is not optional — without an R185, the beneficiary cannot properly complete their own tax return or claim credit for tax paid.

How beneficiaries declare income

A beneficiary reports amounts on the SA107 (Trusts etc.) supplementary pages and enters the gross figure. They then claim credit for tax the trustees have already paid, shown on the R185. This prevents double taxation on the same income.

Grossing up and practical example

If a beneficiary receives £550 net from a discretionary trust, the grossing up works as follows: the trustees paid tax at 45%, so the gross amount was £1,000 (£1,000 × 55% = £550 net). The beneficiary declares £1,000 on their return and claims the £450 as a tax credit. A basic-rate taxpayer (20%) would reclaim £250. A non-taxpayer could reclaim the full £450. A higher-rate taxpayer (40%) would have no further tax to pay, as 45% was already deducted.

Quick trustee checklist

  • Issue annual R185 (Trust Income) statements to each beneficiary who received a distribution.
  • Prepare figures for the SA900 trust and estate tax return.
  • Show gross amounts and tax paid so beneficiaries can complete SA107 accurately.
  • Keep bank evidence, allocation notes and trustee minutes for at least six years (HMRC’s standard retention period).

For specific guidance on bare arrangements, see our note on bare trust inheritance tax.

How to report and pay tax when income is mandated to the beneficiary

If a payer sends receipts directly to the entitled person under a valid mandate, the recipient carries the reporting obligation and any resulting liability.

What to include on Self Assessment

The beneficiary should enter the gross amount received for each source. Use the SA107 (Trusts etc.) supplementary pages for trust-related receipts and match descriptions to bank and platform statements. Where income is received directly from a payer (e.g. bank interest credited to the beneficiary’s account, or dividends paid directly), it may instead go on the relevant standard Self Assessment pages for savings or dividend income.

Include: gross sums, the date you received them, and any tax already deducted so you can claim the credit.

How outcomes differ by taxpayer type

Basic-rate taxpayers may see little extra to pay once allowances apply — and the personal savings allowance (£1,000 for basic-rate taxpayers, £500 for higher-rate taxpayers) can shelter some bank interest entirely.

Higher-rate taxpayers often face more to pay because the additional sums push them further into the 40% band.

Non-taxpayers should still report. If their total income falls within the personal allowance (currently £12,570), they may reclaim any tax deducted.

Practical records to keep

  • Payment dates and gross amounts.
  • Bank evidence and platform distribution statements.
  • A copy of the mandate instruction given to the payer.
  • A short allocation note explaining how each sum relates to the beneficiary’s entitlement under the trust deed.

“Clear allocation notes reduce disputes and make it easier to show what happened if HMRC asks later.”

When to seek advice: get help where trust deed wording is uncertain, payments come from mixed assets (part capital, part income), or there is any question about whether settlements legislation applies. Early advice avoids mistakes and unexpected liability across a tax year.

What to keepWhy it mattersAction
Gross payment recordShows taxable amountEnter on Self Assessment and keep bank evidence
Tax deducted noteAllows credit claimRecord amount and source; attach to return figures
Allocation note and mandate copyResolves family queries and HMRC checksExplain dates, sources and beneficiary entitlement under the trust deed

Special situations that change liability: settlors, spouses and minor children

Some family arrangements quietly shift who carries the tax burden, even when someone else receives the cash. The settlements legislation in UK tax law is designed to prevent income being diverted to a lower-rate taxpayer.

When income is treated as the settlor’s under settlements legislation

Where the settlor or their spouse or civil partner can benefit from the trust, HMRC’s settlements legislation can apply. In these cases the law treats the trust income as the settlor’s for tax purposes, regardless of who actually receives the cash. This is what makes a trust “settlor-interested.”

Practical effect: even if a spouse, civil partner or minor unmarried child gets the income, the settlor may bear the full tax liability and must declare the income on their own Self Assessment.

How trustees account when the settlor is taxable

Trustees pay tax on the income as it arises and file the SA900 trust and estate tax return. They must also provide the settlor with a clear statement showing the gross amounts and the tax paid on their behalf.

What the settlor then does: report the trust income figures on their own Self Assessment and claim credit for the tax the trustees have already paid. If the settlor’s marginal rate is lower than the trust rate, they may be able to reclaim the difference.

“Cashflow and liability do not always match. Clear records prevent family confusion.”

  • Common triggers: the settlor or their spouse/civil partner is included as a potential beneficiary; payments to minor unmarried children of the settlor where income exceeds £100 per year from that settlor’s trust.
  • Trustees’ duty: keep evidence, pay the tax, and issue a statement to the settlor promptly after the tax year.
  • Risk: families often assume the person who receives the cash pays the tax, but liability can remain entirely with the settlor.

Trust Registration Service requirements and deadlines trustees must meet

Registering with the Trust Registration Service (TRS) is a mandatory step that trustees must not overlook. The system exists to increase transparency and help prevent money laundering, in line with the requirements introduced by the 5th Money Laundering Directive. It affects the vast majority of UK express trusts — including many that have no tax liability at all.

Which arrangements need registration

Most UK express trusts must be registered, including discretionary trusts, interest in possession trusts and bare trusts — even where there is no current tax liability. There are limited exemptions (for example, certain pension scheme trusts, charitable trusts already registered with the Charity Commission, and some insurance policy trusts), but trustees should check the scope carefully rather than assuming an exemption applies.

Deadlines and updates

New trusts must register within 90 days of creation. Any changes — for example to trustees, beneficiary details or trust assets — must be updated on the TRS within 90 days. Taxable trusts must also update the register annually by 31 January following the end of the tax year.

Information to prepare

  • Settlor details (name, date of birth, address, National Insurance number or UTR).
  • Trustees names, addresses and contact details.
  • Beneficiary names (or class descriptions where beneficiaries are not yet identified, e.g. “the children and grandchildren of the settlor”).
  • Trust assets and values (required for taxable trusts).

After registration and penalties

Taxable trusts receive a Unique Taxpayer Reference (UTR) for filing the SA900. Non-taxable trusts receive a Unique Reference Number (URN). These identifiers are needed for future returns and correspondence with HMRC.

Penalties can apply for late registration and may increase the longer the delay continues. While HMRC has sometimes taken a pragmatic approach during the initial roll-out, penalties are real and avoidable with prompt action. Importantly, the TRS register is not publicly accessible (unlike Companies House) — only certain persons with a legitimate interest can request information. If you need guidance, see how to register a trust.

How to stay compliant year-on-year as a trustee or beneficiary

We recommend a short, repeatable routine to keep records tidy and risks low. Follow a simple timetable each tax year and you will avoid last-minute stress.

Annual checklist for the tax year

  • Confirm receipts: list all income received by the trust (or mandated to beneficiaries) with gross amounts for the year ending 5 April.
  • Check tax paid: note any tax deducted at source and any tax paid by trustees on the SA900.
  • Issue statements: trustees should send R185 (Trust Income) forms to beneficiaries promptly after 5 April.
  • Store evidence: bank statements, platform reports, mandate instructions and allocation notes for at least six years.
  • Update TRS: check whether any details on the Trust Registration Service need updating and do so within 90 days of any change.

When to register for Self Assessment

If a beneficiary who does not usually file a tax return receives mandated payments or income from a bare trust, they must register for Self Assessment by 5 October after the tax year in which the income arose. Failing to register in time can result in late filing penalties.

When to seek professional advice

Get specialist advice for mixed assets, cross-border elements, unclear trust deed wording, potential settlor-interested issues, or any changes to the trust that might affect who must pay tax. The law — like medicine — is broad: you would not want a generalist handling specialist trust tax work. Early professional help saves time and reduces the risk of costly mistakes.

“Consistent admin protects family assets and keeps the tax return straightforward.”

Conclusion

Confirm the trust arrangement and the payer’s instruction before you assume who bears the tax. First identify the type of trust — interest in possession, discretionary, bare or settlor-interested — and whether receipts pass directly to the named beneficiary under a valid mandate.

Then follow a clear path: check the correct income tax rates, decide who reports, and keep simple, dated records that match bank statements. Good records prevent questions later.

Trustees must remember the £1,000 standard rate band and that dividend allowances do not apply to trustee-held receipts. Beneficiaries receiving mandated payments should use the right Self Assessment pages (SA107 where applicable) and keep evidence to support their figures.

Registering on the TRS and keeping it updated is part of routine housekeeping for all express trusts in England and Wales. If a case feels complicated — mixed income streams, settlor-interested questions, or cross-border elements — get specialist advice early to save time, cost and stress, and to protect your family. England invented trust law over 800 years ago, and the framework remains one of the most powerful tools for protecting family wealth — but only when it is administered correctly.

FAQ

What does it mean to “mandate” trust income to a beneficiary?

Mandating income means the trustees instruct the payer (such as a bank, investment platform or tenant) to pay income from trust assets straight to a named beneficiary rather than to the trustees. The beneficiary then receives the cash directly and is treated by HMRC as having received that income for tax purposes. This most commonly happens with interest in possession arrangements where a life tenant has the right to income from the trust assets as it arises.

How does mandating income change who reports and pays tax?

When income is validly mandated, the beneficiary normally includes that income on their own Self Assessment return and pays any tax due at their personal marginal rate. Trustees still report the trust’s affairs on the SA900, but they can show the mandated amounts. The beneficiary receives relief for any tax already paid by trustees, where applicable. The precise reporting steps depend on the trust type and whether tax has already been deducted at source.

When is mandating typically used in interest in possession arrangements?

It is used where a life tenant has the right to receive regular income from the trust assets, such as rent, bank interest or investment dividends. Trustees mandate the income to ensure the beneficiary gets cash for living costs while trustees retain control of the capital assets. It provides a clear separation of income flows for both practical and tax reasons, and can be more tax-efficient because the beneficiary may pay less tax at their marginal rate than trustees would at the trust rate.

Which trust types change the tax rules I must follow?

Tax treatment depends on the trust arrangement. Interest in possession trusts treat the life tenant as entitled to income, with trustees paying basic-rate tax on their behalf. Discretionary and accumulation trusts tax income at the higher trust rates (45% for non-dividend income, 39.35% for dividends above the £1,000 standard rate band) and distributions are made at trustees’ discretion. Bare trusts tax the beneficiary as the owner, allowing use of personal allowances. Settlor-interested trusts can bring the settlor back into the tax picture under the settlements legislation.

What happens in an interest in possession trust when income is mandated to the beneficiary?

The beneficiary receives cash directly from the payer and includes that income on their own Self Assessment tax return. Trustees record the mandated payment and continue to administer the capital. Trustees may still need to complete the SA900 trust and estate tax return to record the mandate arrangement and any tax already paid, so the beneficiary can claim relief where appropriate.

What parts of trust administration stay with the trustees even when income is mandated?

Trustees retain legal ownership of the trust assets, manage investments, pay trust expenses and fulfil reporting duties including filing the SA900 and registering on the Trust Registration Service. They remain responsible for capital preservation, maintaining the tax pool, and must keep clear records of mandated payments, bank evidence and allocation notes to support tax positions for both trustees and beneficiaries.

How should a beneficiary report mandated income on Self Assessment?

The beneficiary enters the mandated income on their Self Assessment, usually under the SA107 (Trusts etc.) supplementary pages where required. They declare the gross amount and claim credit for any tax already paid by trustees, supported by the R185 statement. Clear evidence from trustees — payment dates, mandate instructions and statements — makes this straightforward when filing.

When does the £1,000 standard rate band apply to trust income?

The £1,000 standard rate band applies to discretionary and accumulation trusts, allowing the first £1,000 of income to be taxed at basic rate rather than the higher trust rates. It is not a tax-free allowance — tax is still payable, just at the lower rate. The band is divided equally between multiple trusts created by the same settlor, with a minimum of £200 per trust where there are five or more.

Are beneficiaries entitled to the dividend allowance on trust dividends?

Trustees cannot use the personal dividend allowance against income taxed at trustee rates. Dividends retained within discretionary or accumulation trusts are taxed at the dividend trust rate of 39.35% (above the standard rate band). However, interest in possession beneficiaries who receive mandated dividend income treat it as their personal income and can use their own dividend allowance (currently £500) and personal tax bands.

How do trustees calculate taxable trust income and allowable deductions?

Trustees total the trust’s income by category — bank interest, dividends, rental profits — then deduct allowable trust management expenses in the correct order (non-savings first, then savings, then dividends). Only qualifying expenses reduce taxable income. Trustees must keep invoices and clear records to justify deductions and track the tax pool, which determines how much tax credit is available when distributions are made to beneficiaries.

What are trustees’ responsibilities when income is not mandated?

Trustees must pay tax due at the applicable trustee rates, file the SA900 trust and estate tax return and issue R185 (Trust Income) statements to beneficiaries showing gross amounts and tax deducted. They remain responsible for collecting and reporting income, paying tax on undistributed amounts, maintaining the tax pool and keeping accurate accounts for each tax year.

How does grossing up work when trustees have paid tax on trust income?

If trustees have deducted tax before paying income to a beneficiary, the beneficiary declares the gross (pre-tax) amount on their return and claims credit for the tax already taken off. For example, a £550 net payment from a discretionary trust (taxed at 45%) represents £1,000 gross — the beneficiary declares £1,000 and claims £450 credit. This prevents double taxation. Trustees should provide clear R185 figures so the beneficiary can claim the correct credit on Self Assessment.

What must a beneficiary include on their Self Assessment when income is mandated?

They must include the gross amount of mandated payments, any tax credited by trustees and details of the trust on the SA107 pages where relevant. They should keep trustee statements (R185), copies of the mandate instruction and bank evidence in case HMRC asks for verification.

How does the tax position differ for basic‑, higher‑ and non‑taxpayers?

The beneficiary’s overall tax position depends on their total taxable income. Basic-rate taxpayers pay tax on mandated income at 20% (or 8.75% for dividends) after any credits and allowances. Higher-rate taxpayers pay the additional amount due at 40% (or 33.75% for dividends). Non-taxpayers may be able to reclaim all tax taken by trustees but must follow the correct claim procedure with supporting evidence such as the R185 and their Self Assessment return.

What records should trustees and beneficiaries keep for mandated payments?

Keep payment dates, bank statements, mandate instructions, allocation notes, trustee minutes and R185 statements. These show the flow of income and support tax positions for both trustees and beneficiaries. HMRC expects records to be retained for at least six years. Good record-keeping simplifies Self Assessment and reduces the risk of queries.

When is income treated as the settlor’s under the settlements legislation?

If the settlor or their spouse or civil partner can benefit from the trust (making it “settlor-interested”), income may be taxed on the settlor rather than the beneficiaries or trustees. This also applies where a settlor’s trust pays income exceeding £100 per year to the settlor’s minor unmarried child. The settlements legislation is designed to prevent income-splitting with lower-rate taxpayers.

How do trustees deal with tax when the settlor is liable?

Trustees must report the position on the SA900 trust and estate tax return and provide the settlor with a clear statement of gross income and tax paid so the settlor can include the income on their own Self Assessment and claim credit for tax already settled by trustees. Clear documentation of why settlor-interested treatment applies is essential to avoid disputes with HMRC or within the family.

Which trusts must register on the Trust Registration Service and when?

Most UK express trusts must register, including discretionary trusts, interest in possession trusts and bare trusts — whether or not they have a current tax liability. This requirement stems from the 5th Money Laundering Directive. Trustees must register within 90 days of the trust being created and update records within 90 days of any changes. The TRS requires information about settlors, trustees, beneficiaries and trust assets.

What information do trustees need for the TRS and what are the penalties for late registration?

Trustees need names, dates of birth, addresses, National Insurance numbers (or UTRs) and details of trust assets and income. Late registration can lead to penalties and potential increased HMRC scrutiny. The TRS register is not publicly accessible, unlike Companies House. Prompt registration and accurate updates reduce risk and demonstrate compliance.

How can trustees stay compliant year‑on‑year?

Follow an annual checklist: record all income received, note tax paid, issue R185 statements to beneficiaries and file the SA900 trust and estate tax return by the deadline (31 January online, 31 October paper). Register or update the TRS when needed and keep clear minutes of trustee decisions. Store all records for at least six years. Seek professional advice for mixed assets, settlor-interested questions or complex arrangements.

When should trustees or beneficiaries get professional advice?

Seek specialist help when trusts mix capital and income, involve settlor-interested rules, have multiple beneficiaries with different entitlements, include cross-border elements, or when large or unusual transactions occur. A solicitor or tax adviser with trust expertise can clarify reporting obligations, reduce errors and help protect family assets for the long term. As with medicine, trust law is a specialist area — a generalist may miss critical details.
