The UK inheritance tax landscape is shifting beneath families’ feet. The nil-rate band has been frozen at £325,000 since 2009—seventeen years without adjustment for inflation. The residence nil-rate band adds £175,000 for qualifying properties, but tapers away for estates above £2 million. The result: IHT now catches families who would never consider themselves wealthy.

What Changes in 2026 and 2027

From April 2026, Business Property Relief and Agricultural Property Relief are capped at 100% for the first £2.5 million of combined value (raised from an initial £1 million cap in December 2025), with only 50% relief on the excess. The unused allowance transfers between spouses, meaning a couple can shelter up to £5 million. Business owners above these thresholds who assumed BPR would shelter their estates now face a fundamentally different calculation. A single founder with a £6 million business faces approximately £700,000 in IHT where previously there was none.

From April 2027, unspent pension pots will be included in estates for IHT purposes. This is the single largest expansion of the IHT base in a generation—suddenly, retirement savings that were previously exempt become taxable at 40% above the threshold.

The Seven-Year Clock

These changes create urgency. The families who act now—transferring assets into properly structured irrevocable discretionary trusts—start their seven-year clock. Those who wait lose options with every passing month. The mathematics are simple: a transfer made today reaches the seven-year mark in 2033. A transfer delayed until next year does not clear until 2034. Every month of delay costs a month of protection.

Architecture Over Avoidance

The deeper question is not how to avoid a tax. It is how to build an architecture that serves your family across generations, with IHT efficiency as one natural consequence of genuine stewardship. The trust that exists solely to reduce tax is brittle—it invites scrutiny from HMRC and collapses under legislative change. The trust that exists to embody your family’s values, with tax efficiency built into its structure, endures.

With the UK divorce rate at approximately 42%, care home fees consuming the average family home’s equity in four to five years, and IHT thresholds frozen indefinitely, the question is not whether you can afford to set up a trust. It is whether you can afford not to.

Grace can walk you through your options before the April deadlines.
