Trust & Estate Accounts and Tax

Trusts & deceased estates · Specialist team

When the numbers matter most.

Whether you are a trustee with quarterly returns due, or an executor working through a deceased estate, the tax and accounts side gets technical fast. We handle it carefully, accurately, and with the human touch the situation deserves.

Two specialist areas, one calm pair of hands

Trusts and estates sit at the technical end of UK tax. Each trust type — bare, interest-in-possession, discretionary, accumulation, settlor-interested, vulnerable beneficiary, will trust — has its own income tax, CGT and IHT rules, plus the Trust Registration Service to feed every year. Get any of it wrong and trustees become personally liable.

Deceased estates are equally technical and a lot more emotional. Executors have to file the IHT account, manage income tax and CGT during the administration period, prepare estate accounts for the beneficiaries, and keep everything documented in case anyone asks questions later. We have done it dozens of times. We will do the work, explain what is happening at every stage, and handle the unpleasant correspondence with HMRC so you do not have to.

FAQ

Common questions

I have just become a trustee. What do I need to do?
First, register the trust with HMRC via the Trust Registration Service if it is not already. Most trusts (including most will trusts) need to be on the TRS. We will register, then set up annual filings so you never miss a deadline.
What is a 10-year anniversary charge?
For most discretionary trusts, IHT is charged at up to 6% of the trust value every 10 years. The calculation is fiddly because it uses historic nil-rate band figures. We do the maths and file the IHT100.
Do beneficiaries pay tax on what they receive from a trust?
It depends on the trust type. From discretionary trusts, beneficiaries get a 45% tax credit and may reclaim some via self-assessment. From IIP trusts, income flows through with a basic rate credit. We explain the position to each beneficiary in plain English.
I am the executor of an estate. Where do I start?
Get the death certificate, list the assets and liabilities at the date of death, and call us. We will help you decide between the simplified IHT account and the full IHT400, value the estate, manage any income or gains during administration, and produce estate accounts for the beneficiaries.
How long does an estate take to wrap up?
Simple estates: 6 to 12 months. Complex estates with property, investments, business assets or overseas elements: 12 to 24 months. We will give you a realistic timetable on the first call so you can manage expectations with the family.
