HMRC Trust Tax Payment Process: A Clear Guide for Trustees

We write for trustees who want a calm, clear route from “what do we owe?” to “paid and evidenced”. We explain obligations in plain language. Our aim is to reduce worry and avoid last-minute rushes.

As an experienced team, we set out what trustees must do: check whether there is a UK liability, register with the Trust Registration Service (TRS) if required, complete the SA900 trust tax return when needed, and meet the key 31 January deadline for online filing and payment.

We flag the two main areas most trustees encounter: income tax on income arising within a trust, and Inheritance Tax (IHT) charges under the relevant property regime for discretionary trusts. We also show how the tax year timetable works in practice and why leaving matters late adds stress and cost.

Later sections use real examples, like Helen and Graeme, to make figures practical. For now, take comfort: simple steps, good records and clear communication with beneficiaries cut the risk of HMRC enquiries.

Key Takeaways

• Trustees must check liabilities and register with the TRS within 90 days of the trust being created.
• File the SA900 trust tax return and meet the 31 January online deadline.
• Two main areas: income tax on trust income (45% on non-dividend income, 39.35% on dividends) and IHT charges under the relevant property regime.
• Keep clear records to reduce the chance of HMRC enquiries.
• Practical examples later will show how to work the numbers.

Understanding what “trust tax” covers in the UK

We split what a trustee must watch into two practical areas: the yearly income tax side and the Inheritance Tax (IHT) charges that arise at certain events under the relevant property regime. Understanding both — and how they differ — is the foundation of confident trust administration.

Income tax vs Inheritance Tax charges on trusts

Income tax deals with money the trust receives each year — bank interest, dividends, rental income. Discretionary and accumulation trusts have a standard rate band of £1,000 (the first £1,000 of income is taxed at the basic rate before the trust rate applies). Above this, non-dividend income is taxed at 45% and dividend income at 39.35%. Trustees must also account for capital gains tax (CGT) on any disposals of trust assets — currently 24% on residential property and 20% on other assets, with an annual exempt amount at half the individual level (currently £1,500).

Separately, discretionary trusts and other trusts within the relevant property regime face entry charges, ten-yearly periodic charges and exit charges for IHT purposes. These are event-driven rather than annual, and are reported on form IHT100. The two regimes — annual income tax and event-driven IHT — run on completely different timetables and use different forms, so it is important to track both.

Key parties and terms

We keep language simple. The settlor creates the trust and puts assets into it. Trustees hold and manage those assets — they are the legal owners. In English law, a trust is not a separate legal entity in the way a company is; instead, it is a legal arrangement where the trustees hold legal title to the assets for the benefit of others. A beneficiary receives income or capital when the trustees exercise their powers to make a distribution. In a discretionary trust, no beneficiary has a right to anything — the trustees have absolute discretion, and that discretion is what makes these trusts so effective for asset protection.

Why the type matters

The type of trust you administer drives the tax rates, the filing requirements and the key dates you must meet. The SA900 trust tax return covers income and capital gains. Form IHT100 covers IHT events such as entry charges, ten-year anniversaries and exit charges. Identifying the trust type at the outset — by reading the trust deed carefully — prevents errors that can be costly to correct later.

• Common trust assets: the family home, cash, investment portfolios and buy-to-let property.
• Where a trust arises from a will (a will trust), the trust’s tax position may tie into the wider estate administration and the personal representatives’ obligations during the administration period.
• Keep records you can produce if HMRC opens an enquiry — England invented trust law over 800 years ago, and HMRC has had centuries to refine how it taxes them.

For guidance on protecting property and how these rules link to wills, see our practical estate guide at protect your property in trust.

Identify your trust type and its tax position before you pay tax

Pin down the type of trust at the outset — it shapes everything else. The trust type determines your reporting obligations, the tax rates that apply and whether the relevant property regime applies for IHT purposes. In the UK, trusts are primarily classified as either lifetime trusts (created during the settlor’s lifetime) or will trusts (arising on death), and then by how they operate: discretionary, bare or interest in possession.

Accumulation or discretionary trusts

These are by far the most common type of trust used in UK estate planning — accounting for the vast majority of family trusts. Trustees have absolute discretion over whether to accumulate or distribute income and capital. No beneficiary has a right to anything — that discretion is what makes these trusts so effective for protection against care fees, divorce, bankruptcy and family disputes. Discretionary trusts can last up to 125 years under English and Welsh law.

Why it matters for tax: retained income is taxed at the trust rate (45% on non-dividend income, 39.35% on dividends). These trusts sit within the relevant property regime for IHT, so entry charges, ten-year periodic charges and exit charges may apply. However, for many family trusts holding assets below the nil rate band (currently £325,000, frozen until at least April 2031), these IHT charges are often zero.

Interest in possession trusts

A beneficiary with a right to receive income as it arises (the “life tenant”) changes the income tax position significantly. The life tenant is treated as receiving the income for income tax purposes and reports it on their own Self Assessment return at their marginal rate — not the 45% trust rate. This is common in will trusts, where a surviving spouse receives income from the estate during their lifetime, with the capital passing to children on the spouse’s death (protecting against sideways disinheritance). Post-March 2006 interest in possession trusts are generally treated as relevant property for IHT unless they qualify as an immediate post-death interest (IPDI) or a disabled person’s interest.

Bare trusts

Here the beneficiary is absolutely entitled to the trust assets — the trustee is merely a nominee. The beneficiary is treated as the owner for income tax and CGT purposes, and reports income and gains at their own rates. Bare trusts sit outside the relevant property regime. Since the beneficiary can collapse the trust once they reach 18 (under the principle in Saunders v Vautier), bare trusts offer no asset protection, cannot protect against care fees or divorce, and are not IHT-efficient. They are the simplest form of trust but provide the least planning benefit.

Assets, income and what you hold

Different income streams — bank interest, dividends, rental property income — follow different rates and reliefs. Match each income type to your trust type before you file. For example, a discretionary trust receiving rental income pays 45% on the net rental profit above the standard rate band, whereas the life tenant of an interest in possession trust reports rental income at their own marginal rate. If the trust holds a residential property that is sold, CGT applies at 24% (with the trust’s annual exempt amount currently £1,500). Holdover relief may be available when assets are transferred into or out of certain trusts, deferring any immediate CGT charge.

Quick year-end checks: confirm the trust type by reviewing the trust deed, list income by source, and note any distributions made. If you have mixed assets, historic additions or are unsure about the trust’s classification, seek specialist advice — the law, like medicine, is broad, and trust taxation is a specialist area.

HMRC trust tax payment process: a step-by-step overview

We give a simple four-step map you can reuse each year. Follow it to move from uncertainty to a clear, evidenced outcome.

Step 1: Confirm whether the trust has a UK tax liability for the tax year (6 April to 5 April). Check income against the £1,000 standard rate band and review whether any distributions were made. Consider whether any trust assets were disposed of, triggering a potential CGT liability. If in doubt, note the figures and seek brief specialist advice.

Step 2: Register with the TRS or confirm existing registration and ensure you have the correct Unique Taxpayer Reference (UTR). All UK express trusts — including bare trusts — must be registered on the TRS within 90 days of creation following the implementation of the 5th Money Laundering Directive. The UTR is essential for HMRC to match your return and payment to the correct trust. Importantly, the TRS register is not publicly accessible (unlike Companies House), so registration does not compromise your privacy.

Step 3: Prepare figures and complete the correct return. Collect bank interest certificates, dividend vouchers, rental schedules and details of any trust expenses before you start the SA900. Keeping tidy source documents reduces errors and rework. If assets were sold during the year, gather acquisition costs, disposal proceeds and dates for the CGT calculations.

Step 4: Pay the amount due by the deadline and keep evidence. Bank confirmations, payment references and trustee minutes showing who approved the payment all matter. Store these alongside the return for the relevant tax year.

“Plan backwards from key dates — 31 January matters for online Self Assessment — and keep good records to avoid late charges. Plan, don’t panic.”

• Quick summary: check liability, confirm TRS registration, prepare and file the SA900 return, then pay and evidence the amount.
• Remember that IHT events (entry charges, ten-year charges, exit charges) follow different rules and timing to annual income tax returns — they are reported on form IHT100 and have their own separate deadlines.

Registering the trust with the Trust Registration Service (TRS)

Start by checking whether the trust must appear on the TRS — registration is now mandatory for virtually all UK express trusts, and completing it early makes future compliance far simpler.

When registration is required

Since the implementation of the 5th Money Laundering Directive, all UK express trusts must register on the TRS within 90 days of creation — even if they have no tax liability. This includes bare trusts, discretionary trusts and interest in possession trusts. Trusts with a UK tax liability must also register to obtain a UTR for filing the SA900. The TRS register is not publicly accessible (unlike Companies House), so registration does not compromise your privacy or expose the details of your family arrangements.

What information you will need

Gather clear information before you start. Typical details include:

• Settlor name, date of birth, National Insurance number and address
• Full trustee names, dates of birth, contact details and National Insurance numbers (you need a minimum of two trustees)
• Beneficiary or class of beneficiary identities (named individuals or a description of the class — for discretionary trusts, a class description such as “the children and remoter issue of the settlor” is acceptable)
• The date the trust was created and a summary of the assets held

How the TRS links to ongoing compliance

Once registered, the trust receives a Unique Taxpayer Reference (UTR) that links all returns, correspondence and payments. Keep the registration up to date — any change of trustees, addition of beneficiaries or material change in assets means you must update the TRS entry within 90 days so HMRC has the current picture. Failing to update can lead to penalties and complications when you file returns or make payments.

Common stumbling blocks

Missing National Insurance numbers for beneficiaries, unclear settlor details or incomplete asset summaries often slow registration. Prepare the information in advance, store it securely and note which trustee approved each update in the trust minutes. If beneficiaries are minors or do not have National Insurance numbers yet, note their full names and dates of birth — you can update the NI numbers later.

“A correct TRS registration reduces HMRC queries and makes later filings easier. Get it right first time — it saves hours down the line.”

Gather the numbers HMRC expects at the end of the tax year

Collecting neat, dated figures as the tax year closes on 5 April makes filing straightforward and reduces HMRC queries later.

Income sources to capture

List each source of income with dates and totals. Capture bank interest (gross), dividends, rental property receipts (with a breakdown of allowable expenses) and any other income the trust received during the tax year running from 6 April to 5 April. If the trust holds multiple properties, break each one out separately — HMRC expects income and expenses to be identifiable by source.

Tracking assets and allowed costs

Keep a clear ledger of trust assets and separate capital movements from income. Mixing the two creates avoidable errors that can trigger HMRC enquiries.

Record invoices and administration costs. Trustee expenses, professional fees (such as accountancy or legal fees for trust administration), insurance and property maintenance are commonly allowable deductions. Save bills, receipts and notes that explain each cost. Note that trust management costs are deductible against income, but capital expenses (such as property improvements as opposed to repairs) are not.

Recording distributions

Note every distribution to each beneficiary. Record the date, amount and whether you treated it as income or capital at the time. For discretionary trusts, income distributions carry a 45% tax credit that the beneficiary can reclaim if they pay tax at a lower marginal rate. The distinction between income and capital is fundamental — getting it wrong can cause problems for both the trust and the beneficiary on their own Self Assessment return.

Supporting documents and dates

Keep bank statements, completion statements for property transactions, dividend vouchers and trustee minutes. Accurate dates speed up checks and reduce follow-up questions from HMRC. HMRC can enquire into a trust return, so having a complete, dated file is your best defence.

“A tidy numbers pack makes the end of the tax year a tidy file rather than a scramble. Not losing the family money provides the greatest peace of mind above all else.”

Practical checklist: build a running totals sheet that reconciles total income against bank entries and supporting documents. If you need guidance on registering or related steps, see our short guide to registering a trust as a trustee for UK families at register a trust as a trustee.

Calculate income tax due on trust income (rules, rates and allowances)

A quick sense-check of receipts and allowable costs often shows whether the trust has a liability. Start by listing gross interest, net rental profit and any dividends for the year. Note the £1,000 standard rate band — the first £1,000 of trust income is taxed at the basic rate (20% for non-dividend income, 8.75% for dividends) before the trust rate kicks in.

How the standard rate band interacts with taxable income

The £1,000 standard rate band is shared equally between trusts created by the same settlor. If one settlor created four trusts, each gets a £250 standard rate band. Income above the standard rate band is taxed at the trust rate: 45% for non-dividend income and 39.35% for dividend income. If total income is modest and expenses are significant, the liability may be small. Many family trusts that hold only the family home and generate no income (for example, the settlor occupies the property) will have no income tax liability at all.

Different rates by income type and trust type

Rates depend on both the income type and the trust type. For discretionary and accumulation trusts, the key rates are:

• Non-dividend income (interest, rent): 45% (above the standard rate band)
• Dividend income: 39.35% (above the standard rate band)

Interest in possession trusts are different — the life tenant reports the income at their own marginal rate, which may be 20%, 40% or 45% depending on their personal circumstances. Bare trusts are transparent: the beneficiary is treated as receiving the income directly and reports it at their own rates.

Worked example: interest and property income

Example: a discretionary trust receives gross bank interest of £600 and net rental income (after allowable expenses) of £4,400, giving total income of £5,000. The first £1,000 is taxed at the basic rate of 20% = £200. The remaining £4,000 is taxed at 45% = £1,800. Total income tax due: £2,000. Record this calculation clearly alongside supporting documents so that if HMRC queries the return, you can demonstrate exactly how the figure was reached.

When beneficiaries must report income

If trustees of a discretionary trust distribute income to beneficiaries, the distribution carries a 45% tax credit. Beneficiaries must include the gross distribution on their Self Assessment return. A basic-rate taxpayer can reclaim the difference between 45% and 20%, which means they receive a meaningful refund. A higher-rate taxpayer (40%) would also be entitled to a partial reclaim. Provide each beneficiary with an R185 (Trust Income) certificate showing the amount, the date and the tax credit, so they can report correctly and claim any refund due.

“Keep simple records and give beneficiaries a clear R185 certificate each year — it saves everyone time and avoids last-minute chasing when Self Assessment deadlines approach.”

For trustees’ wider responsibilities see trustees’ tax responsibilities.

Complete and submit the Trust and Estate Tax Return (SA900)

The SA900 brings together income, capital gains and distribution details in one formal return. This is the form trustees use to report what the trust received during the tax year (6 April to 5 April) and how income was allocated or distributed. Complete it with care — accuracy reduces follow-up HMRC enquiries.

What the SA900 covers: income, gains and distributions

The SA900 captures: bank interest, dividends, rental receipts, capital gains and records of distributions to beneficiaries. Capital gains within trusts are taxed at 24% for residential property and 20% for other assets, with an annual exempt amount currently at half the individual level (currently £1,500). The return links individual items to the overall figures so HMRC can reconcile entries. If the trust disposed of assets during the year, a supplementary capital gains schedule is needed alongside the main return.

Online filing timeline and the key 31 January deadline

File online by 31 January following the end of the tax year. For example, the 2024/25 tax year (ending 5 April 2025) must be filed by 31 January 2026. Late submission triggers an automatic £100 penalty, with further penalties accruing after 3 months, 6 months and 12 months. We recommend an internal calendar with milestones: draft figures by October, review in November, final checks in December and submit by mid-January to allow a buffer. If you file on paper rather than online, the deadline is earlier — 31 October — so online filing gives you significantly more time.

Common mistakes that delay processing or trigger penalties

These errors cause problems:

• Mismatched totals between supplementary schedules and the main SA900 return.
• Missing distribution details or unclear treatment of a payment as income or capital.
• No asset disposal summaries to support capital gains figures.
• Wrong UTR or missing TRS registration reference.
• Failing to issue R185 certificates to beneficiaries, leading to their returns being incorrect too.

“A tidy file and a simple calendar cut the chance of penalties. Plan, don’t panic.”

Before you submit — quick checklist:

Follow the checklist and keep a copy of the submitted SA900 and all supporting information. That makes answering any HMRC enquiry straightforward and keeps trustees confident the return reflects the year’s position accurately.

Make the payment to HMRC correctly and on time

Choosing how and where to send funds is as important as knowing the amount due. We focus on payment methods, references and simple records so the payment matches the return and everyone stays confident.

Choosing the right payment method and reference

Use the correct HMRC bank account and include the trust’s UTR as the payment reference. If you send money without the correct reference, it can sit unallocated at HMRC while they try to match it. That delays clearance and can generate unnecessary interest charges — even though you have paid on time.

Faster Payments (online bank transfer), BACS or CHAPS all work. Confirm the receiving account details shown on HMRC’s official guidance pages and use the trust’s UTR as the payment reference. Note that cheque payments take longer to clear and the deadline is earlier — allow extra time. Direct Debit is also available if set up in advance through HMRC’s online services.

Request a reference before sending money

If a UTR is needed but not yet available (for example, if TRS registration is still being processed), our practical rule is: request first, pay after. Contact HMRC’s trusts helpline and wait for the UTR to be issued.

Paying before you have the reference means the payment may arrive at HMRC without the information they need to allocate it to your trust’s account. That creates unnecessary complications and can result in penalty notices being issued even though funds have been received.

What happens if you miss the deadline

Missing the 31 January payment deadline means interest starts to run immediately on the overdue amount. Interest is calculated daily at HMRC’s prevailing rate. If payment is more than 30 days late, a 5% surcharge applies on the amount still outstanding. Further surcharges follow at 6 months and 12 months.

Contact HMRC early if you think you will miss the deadline. They may agree a Time to Pay arrangement, which can prevent surcharges if you act proactively. Being upfront with HMRC is always better than ignoring the problem — they deal with thousands of trustees and will usually work with you if you communicate honestly.

Simple records every trustee should keep

Keep these items for your file:

• Bank confirmation or screenshot showing the date, amount and payment reference;
• The UTR used as the payment reference;
• A short entry in the trustee minutes recording the payment decision and approval — this evidences proper governance.

“A correct reference beats a hurried transfer every time.”

Paying Inheritance Tax charges for discretionary and relevant property trusts (IHT100)

When discretionary trusts hold capital, IHT charges under the relevant property regime can apply and trustees must watch timing closely. These charges are entirely separate from the annual income tax return and have their own deadlines, forms and calculation methods.

Transfers into a discretionary trust are treated as chargeable lifetime transfers (CLTs). Values above the settlor’s available nil rate band (currently £325,000, frozen since 2009 and confirmed frozen until at least April 2031) face a 20% entry charge on the excess. For example, Helen transferred £400,000 into a discretionary trust; with a £325,000 nil rate band the taxable excess was £75,000, giving an entry charge of £15,000. Trustees report this on form IHT100, and payment falls due within six months after the end of the month in which the transfer was made. For most families putting their home into trust — with the average home in England worth around £290,000 — the entry charge is zero because the transfer falls within the nil rate band.

Seven-year rule and further liability

If the settlor dies within seven years of the CLT, the transfer is reassessed at the full death rate of 40% (with credit for the 20% already paid). Taper relief may reduce the tax — but crucially, taper relief only applies where the CLT exceeds the nil rate band. The taper works as follows: 0–3 years: 40%, 3–4 years: 32%, 4–5 years: 24%, 5–6 years: 16%, 6–7 years: 8%. If the settlor survives the full seven years, no further IHT charge arises on the CLT. Keep records of exact transfer dates and values to make any later recalculation straightforward.

Note that the seven-year rule for CLTs into discretionary trusts works differently from the potentially exempt transfer (PET) rules that apply to outright gifts to individuals. Transfers into discretionary trusts are CLTs — they are immediately chargeable at the lifetime rate, not PETs.

Ten-year periodic charges and exit charges

At each ten-year anniversary a periodic charge is due. The maximum effective rate is 6% of the trust property value above the available nil rate band. For many family trusts holding a property valued below the nil rate band, this charge is zero — and will remain zero for as long as the trust assets stay below that threshold.

Exit charges apply when capital leaves the trust between ten-year anniversaries. The exit charge is proportionate to the last periodic charge — typically well under 1% of the value distributed. As Mike Pugh puts it: “10% of 6% is 0.6% — less than 1%.” Within the first ten years (before any periodic charge has been calculated), trustees use a formula based on the hypothetical entry charge and the number of complete quarters since the trust was created.

“Check for exit charges before you distribute — the numbers and forms matter. But for most family trusts, the charges are modest or nil.”

For practical guidance on protecting family assets and understanding IHT planning, see our guide to secure your family’s future.

Handling distributions to beneficiaries without creating avoidable tax problems

A short, clear distribution note saves beneficiaries hours when they complete their Self Assessment return. Prepare one for every payment that shows the amount, the date and whether it was paid from income or capital.

Income vs capital distributions and why the distinction matters

The label matters because it changes how a beneficiary reports the receipt and how the trust’s position is shown on the SA900.

Income distributions from a discretionary trust carry a 45% tax credit and must appear on the beneficiary’s Self Assessment. The beneficiary receives an R185 certificate. A basic-rate taxpayer can reclaim the difference between 45% and 20% — that is a 25% refund on the gross amount, which can be significant. A higher-rate taxpayer (40%) can also reclaim 5%. Capital distributions from a discretionary trust are not subject to income tax, though they may trigger exit charges under the relevant property regime and could affect the beneficiary’s CGT position if the trust transferred chargeable assets to them rather than cash.

Providing beneficiaries with the information they need for their tax returns

Give each beneficiary a short summary — ideally an R185 (Trust Income) certificate for income distributions — that includes: amount, date, nature (income or capital) and the tax credit rate applied. For capital distributions, a simple letter confirming the amount, date and that it was a capital payment is sufficient.

“A one-page R185 certificate avoids last-minute chasing and reduces errors on the beneficiary’s tax return.”

Planning distributions around key dates to reduce complexity

Consider timing distributions to fall cleanly inside a single tax year (6 April to 5 April). That keeps calculations simple and avoids splitting the same distribution across two returns. If a beneficiary is likely to move between tax bands (for example, retiring mid-year), timing the distribution to fall in the year when their marginal rate is lowest maximises the refund they can claim on the 45% tax credit.

• Document the distribution decision in trustee minutes — this evidences the trustees exercised proper discretion, which is essential for a discretionary trust.
• Keep one file with distribution records, R185 certificates and supporting receipts.
• Send the yearly summary to beneficiaries well before the 31 January filing deadline so they have time to include the figures on their own return.

Conclusion

Focus on the essentials: confirm liability, gather clear information, complete the right return and keep proof of every action.

Remember the two timelines you juggle: the annual income tax filing route with its key 31 January deadline, and the event-driven IHT deadlines under the relevant property regime (typically due within six months of the event). Check the trust deed to confirm which rules and rates apply to your trust.

Good records protect trustees. Save supporting documents, keep a distributions log with R185 certificates and retain proof of submission and payment. Small date differences or prior transfers can change the outcome, as our worked examples show. The nil rate band has been frozen at £325,000 since 2009 and is confirmed frozen until at least April 2031 — so more families are affected by these charges than ever before, making accurate compliance all the more important.

If your trust spans many years, involves property or complex distributions, seek specialist help so you can act with confidence. The law — like medicine — is broad, and trust taxation is a specialist area. Trusts are not just for the rich — they’re for the smart. Getting the administration right is part of that.
