Frozen allowances and major reforms to business reliefs and pensions are reshaping estate planning across Wales.
A Quiet Tax Change With Wider Consequences
UK inheritance tax has been quietly transformed over the past two years. Measures announced in the Autumn Budget 2024 are now taking effect, with restrictions on Business Property Relief and Agricultural Property Relief applying since 6 April 2026. Most unused pension funds and pension death benefits will be included in taxable estates from 6 April 2027.
The nil-rate band remains at £325,000, and the residence nil-rate band at £175,000, both frozen through the 2030 to 2031 tax year. HMRC recorded a record £8.5 billion in inheritance tax receipts during 2025 to 2026. The Office for Budget Responsibility expects receipts to reach £15 billion by 2030 to 2031.
Why More Families Are Revisiting Their Plans
Inheritance tax is generally charged at 40 per cent on the taxable value of an estate above the available allowances. The nil-rate band remains £325,000 per person, while the £175,000 residence nil-rate band may apply when a qualifying home passes to direct descendants. Where all available bands transfer between spouses or civil partners, a qualifying couple may pass on up to £1 million without inheritance tax.
The main nil-rate band has remained unchanged since 2009, with both thresholds now frozen through the 2030 to 2031 tax year. HMRC recorded £8.5 billion in inheritance tax receipts during 2025 to 2026, while the Office for Budget Responsibility expects receipts to continue rising. The landscape has also become more complex following the April 2026 restrictions on Business Property Relief and Agricultural Property Relief, with most unused pension funds and pension death benefits due to enter taxable estates from April 2027. For Welsh families whose estates may include homes, farms, owner-managed businesses, investments and pension savings, these changes have made existing arrangements increasingly important to review.
McCarthy Wealth, a trading style of Clarity Wealth Management LLP, provides estate and lifestyle planning from its trading address in Caerphilly to clients across Wales and the wider UK. The firm, which has published guidance on using a trust for inheritance tax planning, is authorised and regulated by the Financial Conduct Authority under Firm Reference Number 575252. According to Adam McCarthy at McCarthy Wealth, inheritance tax conversations among Welsh families have shifted meaningfully in both tone and urgency as the effects of frozen thresholds and the restrictions on Business Property Relief and Agricultural Property Relief become clearer in practical estate planning decisions.
Business and Farm Relief No Longer Work as Before
Business Property Relief has long covered qualifying trading businesses, partnerships and unquoted shares, commonly subject to two years’ ownership.
Under the rules applying from 6 April 2026, the combined allowance for 100 per cent Business Property Relief and Agricultural Property Relief is £2.5 million. Qualifying value above that amount generally receives 50 per cent relief, producing an effective inheritance tax rate of up to 20 per cent on the excess. Unused allowance may transfer to a surviving spouse or civil partner.
For £3 million of qualifying business property, £2.5 million may receive full relief. The remaining £500,000 receives 50 per cent relief, leaving £250,000 potentially taxable. At 40 per cent, that could mean £100,000 before other allowances or exemptions.
Certain qualifying AIM shares now receive 50 per cent rather than 100 per cent relief. Welsh farming families and business owners whose succession plans relied on the former rules, therefore, have reason to review their calculations.
Pensions Enter the Estate From April 2027
Unused pension funds have historically sat outside the estate in many circumstances.
HMRC’s May 2026 technical note confirms that, from 6 April 2027, most unused pension funds and pension death benefits will be included in the estate for inheritance tax. Death-in-service benefits from registered pension schemes remain outside the measure.
This does not automatically make earlier withdrawals appropriate. It means pension nominations, retirement income, other assets, and potential inheritance tax exposure need to be considered together. Plans based on pensions remaining outside the estate will no longer reflect the general position from April 2027.
Trusts Remain Useful, but the Rules Are Complex
A trust separates legal ownership from the benefit intended for beneficiaries. Depending on its structure, it may help control when assets pass or reduce an estate over time.
The seven-year rule is often associated with outright lifetime gifts, but it does not apply identically to every trust. Transfers into some trusts can face inheritance tax on entry. Relevant-property trusts may also face ten-yearly and exit charges, alongside possible income tax and capital gains tax.
Gift with Reservation of Benefit rules can keep an asset within the estate where the donor continues to benefit from it. Pre-Owned Asset Tax may also apply.
Bare, discretionary, and interest-in-possession trusts operate differently, while loan and gift trusts serve more specific purposes. Trusts are not shortcuts or guaranteed tax savings. Proper legal, tax, and financial advice is required.
Planning Conversations Are Becoming More Urgent
“The tone of inheritance tax conversations has shifted noticeably over the past eighteen months. Families and business owners are asking how the April 2026 relief changes and the 2027 pension rules will interact with wills, gifting and trusts. Starting earlier allows more time to understand the trade-offs, while regular reviews matter because the legislation has changed quickly.”
A Useful Review Starts With the Whole Estate
A practical review begins with current valuations for property, business interests, investments, pensions, life policies, and valuable possessions. Wills and existing trusts should be checked against current law, family intentions, and the suitability of trustees.
Timing matters. The £3,000 annual gifting exemption and the seven-year treatment of some larger gifts can be relevant, but affordability, record-keeping and continued access to assets should not be overlooked.
Gifting, trusts, pensions, business relief, and life insurance should be considered together. Family conversations can clarify intentions.
Complex estates may require coordinated input from an adviser at an FCA-authorised firm, a solicitor, a STEP-qualified estate practitioner and a tax accountant. Even recent arrangements may benefit from periodic review.
Earlier Planning Preserves More Choices
Inheritance tax planning in 2026 is more complex than it was three years ago. Frozen allowances, record receipts, the April 2026 relief restrictions, and the April 2027 pension reform have changed the questions Welsh families need to ask.
Trusts can form part of a wider plan where they have a clear legal and family purpose. They are not a shortcut, a guarantee, or suitable for every estate.
UK inheritance tax has been quietly changing. The Welsh families and business owners who address it early tend to have the widest range of planning options. Those who wait tend to have the fewest.
This article is for general information only and does not constitute financial, tax, legal, or investment advice. The value of investments and pensions can go down as well as up, and you may not get back the amount you invested. Past performance is not a reliable indicator of future results. Tax treatment depends on individual circumstances and may change in the future. UK inheritance tax rules, including the nil rate band, residence nil rate band, Business Property Relief, Agricultural Property Relief and the treatment of pensions, are subject to legislation and may change. Anyone considering estate planning, including the use of trusts, should take advice from a qualified financial adviser, solicitor, and tax accountant appropriate to their circumstances.
