Trusts, Wills & Inheritance Tax: A Complete Guide

Estate planning is the process of organising your financial affairs so that your wealth passes to the people you choose, in the most tax-efficient way possible, and with the legal safeguards that protect your family if circumstances change. Without a plan, the default rules of intestacy and the tax system will decide what happens instead — often not what you would have chosen.

Why Inheritance Tax Planning Matters

Inheritance Tax (IHT) is charged at 40% on the value of your estate above the nil-rate band — currently £325,000 per person. For many families, especially those who own property in the UK, this threshold is reached more easily than expected. There are, however, several legitimate strategies available to reduce the IHT your estate will pay.

Key IHT Thresholds (2026/27)

• Nil-Rate Band (NRB): £325,000 per person. Any estate value above this is subject to 40% IHT.
• Residence Nil-Rate Band (RNRB): An additional £175,000 when passing your main home to direct descendants (children or grandchildren).
• Transferable allowances: Unused NRB and RNRB from a deceased spouse or civil partner can be transferred, potentially shielding up to £1,000,000 in a couple’s combined estate.

The Role of a Will

A valid will is the foundation of any estate plan. Without one, your estate is distributed according to the intestacy rules — rules that may not reflect your wishes at all. For example, unmarried partners receive nothing under intestacy, regardless of the length or nature of your relationship.

A well-drafted will specifies exactly who receives what, names executors to administer your estate, and can include instructions about specific gifts, charitable donations, and care arrangements for minor children. It should be reviewed whenever your circumstances change significantly — marriage, divorce, the birth of children, or a major change in assets.

How Trusts Work in Estate Planning

A trust is a legal arrangement in which assets are held by trustees for the benefit of named beneficiaries. Trusts serve several purposes in estate planning:

• Control: Assets in a trust are managed by trustees according to your instructions — you can specify when and how beneficiaries receive them.
• Protection: Trust assets are generally protected from beneficiaries’ creditors or relationship breakdowns.
• Tax efficiency: Depending on the type of trust and how it is structured, assets within it may fall outside your taxable estate after seven years.

Common types include discretionary trusts, bare trusts (often used for children), and life interest trusts (often used following a second marriage). The right trust structure depends entirely on your circumstances, goals, and the needs of your beneficiaries.

The Seven-Year Rule and Gifting

One of the most widely used IHT planning strategies is gifting during your lifetime. Gifts made more than seven years before death are generally exempt from IHT. Gifts made within seven years may still be subject to tax, but on a tapered basis — the closer to seven years, the smaller the potential tax charge.

There are also annual exemptions: you can give up to £3,000 per year entirely free of IHT, in addition to gifts from your regular income, small gifts to individuals, and wedding gifts within set limits.

Business and Agricultural Property Relief

Business Property Relief (BPR) and Agricultural Property Relief (APR) can reduce the IHT value of qualifying business or agricultural assets by 50–100%. These reliefs are particularly valuable for family business owners and farmers, but the qualifying conditions are complex and should be assessed with professional advice.

When to Seek Professional Advice

Estate planning involves law, tax, and financial planning simultaneously — areas that overlap but require different expertise. A financial adviser working alongside a solicitor can help you take a joined-up approach: ensuring your will, trusts, pension nominations, and investment structures all work together towards the same goal.
