Self Assessment for High-Net-Worth Individuals
When income comes from several directions, a tax return stops being a form and becomes a project. This guide explains what is involved and how to keep it under control.
A complex tax return is rarely complicated because of one large number. It is complicated because salary, dividends, rent, interest, gains and business income all arrive on different timetables, from different sources, with different tax rules. Getting it right is mostly about organisation, timing and making sure each piece is reported once and correctly.
Who this guide is for
This guide is for individuals whose Self Assessment return draws on several sources, for example:
- Company directors and shareholders taking a mix of salary and dividends
- Owners of several rental properties, held personally or alongside a company
- People with significant savings, investment income or share portfolios
- Those who have sold or gifted property, shares or other assets during the year
- Partners in a business, or people with more than one business interest
- Anyone whose income is high enough that allowances begin to be reduced or withdrawn
Bringing multiple income streams together
Each type of income is taxed in its own way and in a particular order, so the rate you pay on one source depends on what else you received. Savings and dividend allowances, the personal allowance and the higher and additional rate bands all interact. At higher income levels, the personal allowance is gradually withdrawn, which can create a much higher effective rate on a slice of income.
The practical point is that no single source can be looked at in isolation. A complete picture of the year (employment, business, property, savings, dividends and gains) is the starting point for an accurate return.
Dividends, salary and business interests
If you own or run a company, the way you take money out affects both your personal and the company’s tax position. Salary, dividends, pension contributions and director’s loan account movements each have different consequences, and the timing of a dividend can decide which tax year it falls into.
- Keep dividend vouchers or board minutes for every dividend declared
- Reconcile any director’s loan account at the company year-end
- Record benefits in kind, such as a company car, so they match the company’s reporting
- Include partnership profit shares and any income from other business interests
We look at remuneration across the company and your personal return together, so the figures are consistent and any decisions are made with the full picture in view.
Property portfolios and rental income
With several properties, the work is in the records: rent received, agent statements, repairs, finance costs and the distinction between a repair and an improvement. Finance costs on residential property are generally given as a basic-rate tax reduction rather than a deduction, which matters more the higher your income.
Jointly owned properties need splitting correctly between owners, and properties held through a company are reported separately from those you own personally. Our landlord’s guide to property records covers the day-to-day records in more detail.
Capital Gains Tax
Selling or gifting property, shares or other assets can create a gain that needs reporting. Residential property disposals usually have a separate, shorter reporting and payment deadline, and gifts to anyone other than a spouse or civil partner are generally treated as if sold at market value.
- Keep purchase documents, improvement costs and selling costs for every asset
- Record acquisition dates and how jointly held assets are owned
- Tell us about planned disposals before they happen, not afterwards
Our Capital Gains Tax guide explains the rules and deadlines in more depth.
Organising your records
The single biggest improvement for a complex return is a simple, consistent system. Keeping documents digitally and grouped by income type through the year saves a great deal of time in January. Our free Self Assessment tax return checklist is a useful starting point for what to collect.
- Annual statements from banks, platforms and investment managers
- Consolidated tax certificates for investment portfolios
- P60s, P11Ds and dividend records from any company you are involved with
- Property income and expense records for each property
- Completion statements for anything bought or sold
- Pension contribution and Gift Aid donation records
Planning for tax payments
Where most of your income is not taxed at source, you are likely to make payments on account in January and July as well as a balancing payment. A large one-off gain or dividend can push up payments on account for the following year, and the first year of significant untaxed income can produce a much larger January bill than expected.
Preparing the return early gives you a clear figure months ahead, time to set funds aside, and the chance to consider whether payments on account should be reduced where income is genuinely expected to fall. We aim to give you clear figures and timings, not surprises.

Make an enquiryWorking with your solicitor or financial adviser
Many people with complex affairs already have a solicitor, financial adviser or investment manager. With your permission, we are happy to coordinate with them so that information flows smoothly: investment statements arrive in time, completion statements are shared, and the tax effect of a proposed transaction is understood before it happens.
We do not provide investment or financial advice, and decisions about investments, pensions or legal structures remain with you and your appropriately qualified advisers.
Matters that may need specialist advice
Some areas carry their own rules and may need separately confirmed specialist advice or a referral. These include:
- Trusts, whether you are a settlor, trustee or beneficiary
- Estates and the administration of an estate
- Domicile and the tax treatment of non-UK assets
- UK tax residence, including years of arrival or departure
- International tax and income or gains taxed in more than one country
If any of these apply, tell us early. We will say plainly whether it is something we can support and, where it is not, recommend that you take appropriate specialist advice.
