HMRC Trust and Estates Edinburgh office responsibilities and what this team typically handles
This office handles routine administration and any tax matters that flow from an estate after someone’s death, or from a trust — whether a lifetime trust set up during the settlor’s life or a will trust that takes effect on death. We explain, in clear terms, the main areas you will meet and why cases sometimes move between teams.
Trust and estate tax touchpoints: Income Tax, Capital Gains Tax and Self Assessment links
Every estate or trust can trigger several taxes at different stages. You may see Income Tax on rent, savings interest or dividends received by the estate or trust, Capital Gains Tax (CGT) when an asset is sold or transferred, and Self Assessment reporting when the trust or estate needs to submit a return.
For trusts specifically, trustees must file an SA900 trust and estate tax return each year if the trust has taxable income or gains. Trust income is taxed at 45% on non-dividend income (the trust rate) and 39.35% on dividends, with the first £1,000 taxed at the basic rate. CGT on trust disposals is charged at 24% on residential property and 20% on other assets, with the annual exempt amount currently set at half the individual level (currently £1,500 for trustees). These rates apply regardless of whether the trust is a discretionary trust, a bare trust or an interest in possession trust — though the way the tax burden falls on trustees versus beneficiaries differs depending on the trust type.
We often see cases passed between HMRC teams. That happens when a file covers PAYE, Self Assessment or specific compliance checks. A property sale might need CGT work, while ongoing rental income requires Income Tax handling. If an estate is still in administration, income received during that period has its own tax treatment before it is distributed to beneficiaries. Inheritance tax (IHT), it is worth noting, is handled by a separate HMRC team — not the Trust and Estates Edinburgh office — so IHT queries should be directed to HMRC’s IHT helpline or the Inheritance Tax team at their own postal address.
When you should follow the address on your HMRC letter rather than a generic office address
Use the contact details on any letter you receive. That is usually the fastest route. Letters often start compliance actions or set deadlines. Using a generic contact can slow a reply or cause you to miss an important deadline.
If you have lost the letter, check the category of your query: Self Assessment, PAYE/NIC, trust returns, or complaints. If unsure, note key dates (such as the tax year end, date of death, date the trust was created, or any asset disposal dates) and the type of income or gain before you call or write. For trust-related queries, have the trust’s own UTR to hand — this is separate from any individual’s UTR. If you are a trustee acting in that capacity, you should be able to find the trust UTR on any previous SA900 return or on the Trust Registration Service (TRS) record.
HMRC Trust and Estates Edinburgh address, contact and where to send your enquiry
Before you post or call, gather the key identification details that let HMRC staff find your file quickly.
Have the relevant National Insurance number, the trust or estate UTR, the tax year in question, and key dates to hand. These include the date of death (for estate administration), the date the trust was created (shown on the trust deed), and any disposal dates for CGT purposes. Missing dates slow an enquiry considerably. If an estate is in administration and a Grant of Probate (or Letters of Administration in an intestacy) has been issued, have that reference available too.
Before you write or call: have your National Insurance number and key dates to hand
We suggest copying reference numbers onto every form you submit. Use recorded delivery for urgent or time-sensitive papers. If a specific HMRC office has written to you, reply to that office — not a general line. For trust queries, always quote the trust UTR (which is a separate reference from any individual’s Self Assessment UTR).
Common postal routes
| Service | Purpose | Postal details | When to use |
|---|---|---|---|
| Self Assessment (general enquiries) | Assessment queries, filing help | Self Assessment, HM Revenue and Customs, BX9 1AS, United Kingdom | Use for returns and general assessment questions — including estate Self Assessment returns |
| Change of details | Update personal or contact info | HM Revenue and Customs – Self Assessment, PO Box 4000, Cardiff, CF14 8HR | Send address or name changes here — for example, notifying HMRC of a new personal representative following a death |
| Employer and NI routes | Employer enquiries, NI contributions, PAYE payments | PT Operations North East England, BX9 1BX / BX9 1AN; HMRC Direct, BX5 5BD | Payroll, contributions queries and payment issues |
Practical tip: keep copies of all forms, write the reference on each page and post with a tracked service. If you act as an agent for a trust or estate, see our guidance on registering a trust as an agent. Remember that all UK express trusts — including bare trusts — must be registered with HMRC’s Trust Registration Service (TRS) within 90 days of creation, following the requirements of the 5th Money Laundering Directive. The TRS register is not publicly accessible (unlike Companies House), so registration does not expose your family’s trust arrangements to the public.
Telephone numbers, phone and accessibility options for HMRC trust and estate enquiries
When you need to call HMRC about a trust or estate tax matter, knowing the right phone route saves time and stress.
Finding the correct contact
Match your issue to the correct telephone line: Self Assessment lines for returns (including SA900 trust returns), National Insurance or PAYE lines for contributions and payroll, or the number shown on any HMRC letter if it is case‑specific. Trust and estate queries often have a dedicated helpline number — check the GOV.UK trusts page for the most up-to-date number, as HMRC periodically updates its contact details.
What you’ll be asked and what to have ready
- Identity checks: name, date of birth and National Insurance number where relevant. For trust calls, the trust name and UTR.
- Reference details: Unique Taxpayer References, the reference on any HMRC letter, or any National Insurance number linked to the case.
- Key dates: tax year in question, date of death (for estates), date the trust deed was executed, or disposal dates for CGT assessment purposes.
Calling as an agent requires authority. HMRC will ask for client consent or formal agent authorisation (such as a 64-8 form already on file). If you are a trustee acting on behalf of the trust, confirm your role and have the trust deed reference available. It is worth noting that a trust is a legal arrangement, not a legal entity with its own separate personality — the trustees are the legal owners of the trust property and act on behalf of the trust in all dealings with HMRC.
If you are redirected, asked to write in, or told to use the contact on your letter, follow that route. Ask for reasonable adjustments or relay services if you need them — HMRC provides these as standard.
We recommend calling at quieter times (early morning or mid-afternoon tend to have shorter waits) and keeping notes of the call reference number to speed any follow‑up.
Complaints, debt management and escalation routes (BX9 complaint addresses)
If you need to escalate a problem with HMRC’s handling of a trust or estate matter, there are clear postal routes for complaints and debt management that you should use.
When to complain: use a complaint for delays, poor communication or repeated errors in handling your trust or estate matter. If you need a technical review or want to appeal a tax assessment, follow the formal appeal route instead (you normally have 30 days from the date of the assessment to lodge an appeal). Keep the focus on the service failure and the effect on you, the trust or the estate.
Income Tax and PAYE complaints
PAYE and Self Assessment Complaints, HM Revenue and Customs, BX9 1AB. Use this for Income Tax or Self Assessment service failures and PAYE reporting problems — including cases where estate income has been incorrectly assessed or where a trust’s SA900 return has been mishandled.
National Insurance and employer complaints
NIC and EO Complaints, HM Revenue and Customs, BX9 1AA. Send employer or National Insurance complaints here — for example, where income records or employer payment queries affect the estate administration or where a deceased person’s NI record needs correcting.
Debt management complaints
Debt Management Complaints, HM Revenue and Customs, BX9 1JT. If collection action or a payment plan relating to an estate or trust liability is causing hardship, explain the impact clearly and ask for a halt or review while you provide supporting documents. Executors and trustees have personal liability for unpaid tax on the estate or trust they administer, so getting this resolved promptly is essential.
Compliance check or enquiry complaints
Customer Compliance Complaints, HM Revenue and Customs, BX9 2AB. Use this for complaints about how a compliance check or enquiry into a trust or estate was handled. Keep the complaint factual and stick to process and treatment — HMRC’s own Charter sets out the standards you can expect.
Keep copies of timelines, letters and reference numbers. State clearly what outcome you want and by when.
If you are an agent, note that the online complaints form requires sign‑in via Government Gateway and cannot be used by an agent directly. You must either ask the taxpayer (or personal representative) to submit the online form, or write to the relevant BX9 unit yourself. Include timelines, forms submitted, reference numbers and a clear description of the problem and the resolution you are seeking.
If the complaint is not resolved to your satisfaction, you can escalate to the Adjudicator’s Office, and ultimately to the Parliamentary and Health Service Ombudsman via your MP.

Conclusion
We recommend a simple rule: use the contact shown on any official HMRC letter, or select the correct category from the routes above if you have no letter to hand.
Start by confirming the office to which you will send forms. If you must post, use the BX9 routes or the Cardiff PO Box noted in this guide. That gets papers to the right team quickly and avoids unnecessary delays in the administration of the trust or estate.
Prepare the relevant National Insurance number, trust or estate UTR, key dates and clear references before you call or write. Have copies of all forms and note posting dates. Track replies to avoid repeat enquiries.
It is worth remembering that trust and estate tax obligations sit alongside the wider question of inheritance tax planning. The inheritance tax nil rate band has been frozen at £325,000 per person since 2009 — and is confirmed frozen until at least April 2031. With the average home in England now worth around £290,000, more families than ever are being caught by the 40% IHT charge on estates above the threshold. If you are administering an estate or acting as a trustee, understanding how Income Tax, CGT and IHT interact is essential — and often benefits from specialist advice. As we often say at MP Estate Planning, trusts are not just for the rich — they’re for the smart. England invented trust law over 800 years ago, and proper planning remains one of the most effective ways to protect your family’s wealth.
Next step: keep a simple checklist, use tracked post, and ensure agent authority is in place for complaints or sensitive enquiries. This helps speed assessment, payment and any Capital Gains Tax or Income Tax queries. If you need to register a trust with HMRC’s Trust Registration Service, remember the 90-day deadline from the date the trust was created — this applies to all UK express trusts, including bare trusts.
