Family Office Tax & Accounting Services UK
Complex family wealth needs more than year-end accounts. It needs clear oversight across personal tax, family companies, trusts, estates, property, international assets and succession.

Pearl Lemon Accountants provides family office tax and accounting services for high-net-worth families, business owners and multi-generational wealth structures across London and the wider UK. We coordinate reporting, tax compliance and long-term family wealth planning across multiple entities, helping you understand exactly what is due, when action is required and where unnecessary exposure may exist.
Whether your family structure includes a trading company in London, a family investment company, UK property, overseas assets or several trusts, we bring the accounting and tax work into one organised framework.
From HMRC filings and Companies House obligations to Self Assessment, IHT, CGT and cross-border reporting, our role is to make complex family finances easier to control.

Family Office Services Built Around Complex Wealth
Your family may have one balance sheet in principle, but HMRC, Companies House, trustees, companies and individual family members often see several separate reporting obligations. We connect those moving parts so tax, accounting and succession decisions can be made with better information.

Keep Personal and Family Tax Under Control
Personal Tax Planning | Capital Gains | Self Assessment | Family Wealth
Different family members can have very different tax positions even when their wealth comes from the same underlying businesses or investments.
We review income, dividends, disposals, investment gains, property interests and family transfers so individual tax positions can be considered alongside the wider family structure.
Our work can include:
- Self Assessment returns
- Income and dividend tax calculations
- Capital Gains Tax reporting
- Family wealth transfers
- Tax-year planning
- Record reconciliation across family entities
- Coordination with solicitors and other specialists
For UK families with significant assets, the value is not simply filing another return. It is understanding how one decision at personal level may affect a trust, family company, estate or later succession plan.

Put Family Companies on Firmer Financial Ground
Family Companies | FICs | Corporation Tax | Shareholders
A family office can quickly become harder to manage when wealth sits across trading companies, investment companies and separate property or holding entities.
We support the accounting and tax requirements of family-owned companies, including family investment companies where appropriate.
Our work may cover:
- Annual accounts
- Corporation Tax
- Dividend reporting
- Director remuneration
- Shareholder transactions
- Inter-company balances
- Bookkeeping oversight
- Companies House requirements
- Family investment company accounting
- Reporting across connected entities
The aim is simple: each company should make sense on its own while still fitting into the family’s wider financial picture.

Plan Earlier for IHT and Intergenerational Transfers
Inheritance Tax | Estates | Succession | Family Wealth
Inheritance Tax planning becomes far harder when action begins only after a major life event.
For the 2026/27 tax year, the standard UK IHT nil-rate band remains £325,000, while the residence nil-rate band remains £175,000 where the qualifying rules are met. The residence band begins to taper for estates above £2 million.
We help families examine their current structure before major transfers take place.
This may include:
- Estate exposure reviews
- Lifetime gifting records
- Trust-related tax reporting
- Business and investment holdings
- Family company interests
- Property ownership
- Succession scenarios
- Coordination with your solicitor
The objective is not aggressive tax reduction. It is informed planning within current UK rules, backed by clean documentation.

Keep Trust Accounting and Reporting Organised
Trust Accounting | Trustees | Beneficiaries | HMRC Reporting
Trusts introduce their own tax, accounting and administrative responsibilities.
We support trustees and family offices with bookkeeping, reporting and tax compliance so distributions, income, gains and beneficiary information remain properly recorded.
Support can include:
- Trust accounts
- Trust tax returns
- Distribution records
- Trustee reporting
- Beneficiary records
- Trust Registration Service requirements
- Income and gains calculations
- Coordination with legal specialists
HMRC’s Trust Registration Service rules continue to change, including amendments introduced in 2026, which makes accurate records and periodic reviews particularly important.

Coordinate UK and Overseas Tax Positions
Cross-Border Tax | Overseas Assets | Residence | International Families
Family wealth rarely stays inside one postcode.
A London-based family might own property overseas, have beneficiaries living abroad, receive foreign investment income or hold trusts and companies connected with several jurisdictions.
We help establish the UK reporting position and coordinate information required for overseas specialists.
Typical issues include:
- Foreign income
- Overseas property
- International shareholdings
- Non-UK trusts
- Residence questions
- Double-tax treaty considerations
- Foreign tax documentation
- International family members
The goal is one clear record of what exists, where it sits and which party is responsible for reporting it.

Create Order Across Wealth, Giving and Succession
Philanthropy | Family Governance | Succession | Reporting
A family office often has responsibilities far beyond an annual tax return.
Charitable giving, family succession, trusts, companies and future generations can all create separate accounting records and decision points.
We help organise the financial information supporting these decisions, including:
- Charitable donations
- Trust and foundation reporting
- Family investment structures
- Succession schedules
- Entity-level accounts
- Family reporting packs
- Tax documentation
- Information for solicitors and trustees
A clearer reporting structure gives principals and family members better visibility before significant decisions are made.
Confidence Matters When the Numbers Are Personal
For family-office work, discretion, communication and clarity matter as much as technical accounting.
Before working with Pearl Lemon Accountants, our reporting across multiple holding companies and trusts was fragmented and difficult to track. Their team introduced a structured system that finally gave us visibility across the entire family portfolio. Deadlines, obligations and responsibilities are now clearly mapped, which has removed a huge amount of internal confusion. Their communication has been consistently precise and professional throughout.
Our family structure spans property investments, operating companies and offshore interests, so we needed more than standard accounting support. The team took time to understand how everything connected before producing any reports, which made a significant difference to accuracy. We now have a far clearer understanding of our tax position and reporting obligations. It has improved how we coordinate with our legal and investment advisers.

Family Office Accounting Across London and the UK
From Mayfair family offices to internationally connected UK families, we support complex structures without turning location into another administrative barrier.
Mayfair Family Offices
We support Mayfair-based principals and family offices managing companies, trusts, investment structures and internationally held assets.
Knightsbridge Families
For families around Knightsbridge with property, investments and overseas interests, we coordinate UK accounting and tax reporting across connected entities.
Kensington Wealth Structures
We work with complex personal, corporate and family arrangements in Kensington where multiple ownership structures require clearer reporting.
Chelsea Business Families
Chelsea-based business owners and multi-generational families can use one accounting relationship to coordinate personal and corporate reporting.
City of London Connections
Where family wealth is connected to City businesses, investment structures or professional firms, we organise the accounting information needed across entities.
Canary Wharf and International Families
For families working between Canary Wharf and overseas financial centres, we help establish the UK reporting position and coordinate cross-border information.
UK tax deadlines do not disappear during Christmas, Boxing Day, Easter or the August bank holiday. Where trustees, solicitors, banks or overseas specialists close for holiday periods, we recommend gathering records earlier so a bank holiday does not become the reason an important filing or family decision is rushed.
Complex Family Structures, Made Easier to Understand
6 Entities Brought Into One Reporting Calendar
A clearer timetable for a multi-entity UK family
The Situation
A hypothetical UK family has records spread across three companies, two trusts and personal property interests. Different bookkeepers, trustees and family members hold different pieces of information.
Accounting Requirement
Create one reporting map showing which records belong to each entity, which returns are required and which external specialist needs each document.
Working Structure
Build an entity register, create a deadline calendar, separate personal and company records, reconcile inter-company balances, record trust distributions, and maintain a document request schedule.
Instead of six separate reporting processes being managed from memory, the family office works from one calendar showing responsibilities, documents and deadlines.
£18m Estate Modelled Before Succession Decisions
Earlier visibility before a major family transfer
The Situation
A hypothetical family wants to transfer wealth gradually rather than leave every decision until death or a business sale.
Accounting Requirement
Build a clear schedule of asset ownership, base values, company interests and previous transfers so the family and its legal specialists can consider succession choices using accurate numbers.
Working Structure
Map asset ownership, record historic gifts, identify family company interests, separate personal and trust holdings, produce tax scenario calculations, provide figures to legal specialists, and review changes each tax year.
The family can discuss succession using a documented asset position rather than assumptions, while legal and tax specialists work from the same underlying figures.
3 Jurisdictions Coordinated Through One UK File
Cross-border reporting without three disconnected conversations
The Situation
A hypothetical internationally connected family receives income and owns assets across three tax jurisdictions.
Accounting Requirement
Establish what information is needed for the UK position and create an annual document flow between the family, UK accountant and overseas specialists.
Working Structure
Record assets by jurisdiction, catalogue foreign income, track taxes paid overseas, maintain treaty-related documentation, set document deadlines, reconcile foreign figures to UK reporting, and retain supporting records.
The UK reporting process has a defined source for every figure, reducing duplicated requests and making cross-border discussions easier to manage.

Personal returns, family companies, trusts and estates are considered as connected parts of the same family structure.

Works Alongside Existing Specialists
We can coordinate accounting information with your solicitor, trustee, wealth manager or overseas tax specialist without pretending one profession can replace another.
UK Tax Numbers Family Offices Should Know
These figures show why ownership structures, estates and investment disposals need regular review rather than last-minute calculations.
| UK Tax Measure | Current Figure | Why It Matters |
|---|---|---|
| Standard Inheritance Tax rate | 40% | Can apply to the taxable portion of an estate after available exemptions and reliefs. |
| IHT nil-rate band | £325,000 | Core nil-rate threshold remains frozen. |
| Residence nil-rate band | £175,000 | May apply when a qualifying home passes to direct descendants. |
| RNRB taper threshold | £2 million | Residence nil-rate band begins reducing for larger estates. |
| Main individual CGT rates | 18% / 24% | Relevant to many taxable disposals depending on the taxpayer's position. |
| Business Asset Disposal Relief rate | 18% from 6 April 2026 | Relevant where qualifying business disposals meet the statutory conditions. |
| Typical trust income exemption | £500 | Most trusts have a small income exemption, subject to the applicable rules. |

Holiday periods also matter. Christmas, Boxing Day, Easter and UK bank holidays can reduce availability at banks, law firms and other institutions, so significant year-end work should not be left until offices begin closing.
