How IHT Works

Inheritance tax is charged at 40% on the value of your estate above the nil-rate band (GBP 325,000). The nil-rate band has been frozen since 2009 and will remain frozen until at least 2030. In real terms, adjusted for inflation, it would be approximately GBP 525,000 today.

Married couples and civil partners benefit from the transferable nil-rate band: any unused portion of the first spouse's NRB passes to the surviving spouse, potentially doubling the combined allowance to GBP 650,000. Add the Residence Nil-Rate Band (GBP 175,000 per person when passing a qualifying property to direct descendants) and the combined tax-free amount reaches GBP 1,000,000 for a married couple.

However, the RNRB tapers for estates above GBP 2,000,000, reducing by GBP 1 for every GBP 2 above the threshold. For estates over GBP 2,700,000 the RNRB is completely eliminated.

April 2026: Business Property Relief Reform

Deadline

From 6 April 2026, Business Property Relief is fundamentally changing. The previous regime offered unlimited 100% relief on qualifying business assets. The new regime introduces a GBP 2,500,000 cap at 100% relief (revised up from the initially announced GBP 1,000,000 following significant political backlash in December 2025).

Above the GBP 2,500,000 threshold, only 50% relief applies - meaning an effective IHT rate of 20% on the excess. AIM-listed shares will receive only 50% relief regardless of value, giving a flat effective rate of 20%.

April 2027: Pensions Brought Into IHT

Deadline

From 6 April 2027, unused pension funds will count as part of your estate for IHT purposes. This is arguably the most significant IHT change in decades. Pensions have been the single most effective IHT planning tool - sitting entirely outside the estate, growing tax-free, and passing to beneficiaries free of IHT (though subject to income tax on drawdown).

After April 2027, beneficiaries may face double taxation: IHT on the pension value within the estate, plus income tax when they draw down the inherited pension. For someone with a GBP 1,000,000 pension pot, the combined tax charge could exceed 60% depending on the beneficiary's income tax position.

Death-in-service benefits have been excluded from the change following industry lobbying. Individuals who need to restructure their pension strategy before April 2027 should seek professional advice now - the window is narrowing.

How to Reduce Your IHT Liability

There are several legitimate strategies for reducing IHT. The right combination depends on your specific circumstances, estate composition, and objectives.
