UK Inheritance Tax Reliefs & Estate Planning: Gifts, Trusts & BR (2025/26)

Accounting › Country Tax Guides › UK Tax

UK Inheritance Tax planning uses gifts, reliefs and structures to reduce the 40% charge on death. This guide explains the seven-year gift rule, the annual exemptions, Business and Agricultural Relief, the role of trusts and charitable giving, and how to plan an estate efficiently — while noting which reliefs are under review.

How does the seven-year gift rule work?

Gifts you make during your lifetime generally fall outside your estate for IHT if you survive seven years after making them — these are ‘potentially exempt transfers’. If you die within seven years, the gift may be taxable, but taper relief reduces the tax on gifts made between three and seven years before death. Surviving the full seven years removes the gift from IHT entirely.

This rule is the cornerstone of lifetime IHT planning: giving assets away early, while you’re healthy, can move substantial value out of your taxable estate. The key risk is the seven-year survival requirement, which is why such gifts are often made well in advance. Keeping clear records of gifts and their dates is essential for the executors who must later account for them.

What annual gift exemptions are available?

Several gifts are exempt immediately, without needing the seven-year survival. You can give away £3,000 a year (the annual exemption), make small gifts of up to £250 per person to any number of people, give wedding gifts within set limits, and make regular gifts out of surplus income that don’t affect your standard of living. Gifts to spouses and charities are fully exempt.

These exemptions let you reduce your estate steadily and safely. The £3,000 annual exemption can be carried forward one year if unused, and the gifts-out-of-income exemption is particularly powerful for those with pension or investment income exceeding their needs. Used consistently over years, these allowances transfer meaningful value out of an estate without any seven-year risk.

What are Business Relief and Agricultural Relief?

Business Relief (BR) can reduce the IHT value of qualifying business assets — such as shares in an unquoted trading company or an interest in a business — by up to 100%, removing them from the taxable estate. Agricultural Relief works similarly for qualifying farmland and agricultural property. Both are powerful reliefs that have historically allowed family businesses and farms to pass on without a crippling IHT charge.

However, these reliefs are subject to reform, with changes announced that will limit the full relief available on larger amounts of qualifying business and agricultural assets. Anyone relying on BR or Agricultural Relief in their estate planning should check the current rules carefully and seek advice, as the landscape is shifting and the relief may be less generous than in the past.

How do trusts help with estate planning?

Trusts let you transfer assets out of your estate while retaining some control over how they’re used and who benefits. Putting assets into certain trusts can, after the seven-year period, remove them from your IHT estate, while protecting beneficiaries who are young, vulnerable, or whom you don’t want to give outright control. Different trust types have different IHT treatments and their own charges.

Trusts are a sophisticated tool with their own tax rules, including potential entry, ten-yearly and exit charges, so they need careful structuring and professional advice. They’re particularly useful for larger estates, for providing for children or grandchildren over time, and for keeping assets within a family. Used appropriately, they combine IHT efficiency with control and protection.

How does charitable giving reduce IHT?

Gifts to charity are entirely exempt from IHT, and leaving at least 10% of your net estate to charity reduces the IHT rate on the rest from 40% to 36%. This means charitable bequests can benefit the cause, reduce the tax, and in some cases leave beneficiaries little worse off than if no gift had been made — a genuinely tax-efficient form of giving.

For the charitably inclined, structuring a will to meet the 10% threshold is a way to support good causes while cutting the overall tax. The calculation of the 10% test is specific and worth getting right, as falling just short loses the reduced rate. Charitable giving is one of the few IHT strategies that benefits both the giver’s chosen causes and their other heirs.

How does life insurance fit into IHT planning?

A life insurance policy written in trust pays out directly to beneficiaries on death, outside the taxable estate, providing a lump sum to meet an IHT bill. This is valuable where an estate is illiquid — for example, mostly tied up in a home — so heirs can pay the tax without having to sell assets quickly or at a loss.

Writing the policy in trust is the crucial step; a policy not in trust would itself form part of the estate and could increase the IHT bill. For families with a predictable IHT liability and limited liquid assets, this is a practical, widely used solution that ensures the tax can be paid smoothly while preserving the estate’s key assets for the next generation.

How should I approach estate planning?

Effective estate planning combines a well-drafted will that captures the available allowances, a programme of lifetime gifting within the exemptions and the seven-year rule, use of relevant reliefs, and structures like trusts or life insurance where appropriate. It should be reviewed regularly, as both your circumstances and the rules — including the BR and Agricultural Relief reforms — change.

Because IHT planning blends tax, legal and family considerations, and because the reliefs are evolving, professional advice is usually worthwhile for estates likely to face a charge. Starting early gives the seven-year rule and gifting strategies time to work. Done well, estate planning can substantially reduce or eliminate IHT, ensuring more of what you’ve built passes to the people and causes you care about.

What records should be kept for IHT planning?

Good IHT planning depends on clear records: dates and values of lifetime gifts, evidence that regular gifts came from surplus income, documentation of trusts and their funding, and details of assets qualifying for Business or Agricultural Relief. Executors must account for gifts in the seven years before death, so contemporaneous records make their task — and the IHT calculation — far easier.

Without records, valuable exemptions can be lost and executors may struggle to substantiate the position to HMRC. Keeping a simple log of gifts, their dates and the exemption relied on, alongside copies of relevant documents, protects the planning you’ve done. This record-keeping is an unglamorous but essential part of ensuring your estate plan actually delivers the IHT savings intended.

How do pensions fit into IHT planning?

Pensions have historically sat outside the taxable estate for IHT, making them a valuable way to pass wealth to the next generation, though the treatment of pensions on death is an area of announced reform. Drawing other assets first while preserving pension funds has been a common strategy, but the changing rules mean this needs reviewing against current legislation.

Because pension and IHT rules interact and are both subject to change, coordinating retirement drawdown with estate planning is increasingly complex. The general principle — using the most tax-efficient assets for spending and passing on the rest efficiently — remains, but the specifics are shifting. Anyone with significant pension wealth should review how it fits their estate plan against the latest rules and any announced reforms.

Why start estate planning early

The most powerful IHT strategies — the seven-year gift rule, regular gifting out of income, and funding trusts — all work better the earlier they start, because they need time to take effect. Beginning estate planning in good health and well before it’s needed gives gifts time to fall out of the estate and lets a consistent gifting programme transfer substantial value safely.

Leaving planning until late in life limits the options, as the seven-year rule and gradual gifting can’t be compressed. With the nil-rate band frozen and reliefs under reform, the case for starting early is stronger than ever. Reviewing your estate periodically, drafting a will that captures the allowances, and beginning a gifting strategy in good time are the foundations of effective, low-stress IHT planning.

Common estate-planning mistakes to avoid

Common IHT planning errors include leaving planning too late for the seven-year rule to work, failing to write life insurance in trust, not keeping records of gifts, relying on Business or Agricultural Relief without checking the reforms, and giving away assets you may later need. Each can undermine the plan or create unintended problems.

Avoiding them means starting early, structuring policies and gifts correctly, documenting everything, reviewing reliefs against current rules, and keeping enough wealth for your own security. Because estate planning blends tax, legal and personal factors, and because the rules are changing, regular review with professional advice ensures the plan keeps working as intended and adapts to reform as it comes.

How do gifts and CGT interact in estate planning?

Lifetime gifts can have a CGT dimension as well as an IHT one. Giving away an asset that has risen in value — like shares or a second property — is a disposal for CGT and can trigger a gain, even though the aim was to reduce the estate for IHT. Gift Hold-Over Relief can defer the CGT on gifts of certain business assets, but for many assets the CGT must be considered.

This interaction means estate planning has to balance IHT and CGT together. A gift that saves IHT might create a CGT charge now, and the best route depends on the asset, the values involved and the donor’s circumstances. Considering both taxes when planning lifetime gifts — rather than focusing on IHT alone — is essential to avoid an unexpected CGT bill undermining the estate plan.
