Inheritance tax (IHT) is charged at 40% on the value of your estate above £325,000 when you die — potentially one of the largest tax bills your family will face. However, with careful planning, it is often possible to significantly reduce or even eliminate an IHT liability through entirely legal strategies. The key is to start planning early — many of the most effective strategies require time to work.

The Pension Planning Urgency: Act Before April 2027

Currently, unused defined contribution pension pots pass outside your estate for IHT purposes — making them one of the most tax-efficient inheritance planning vehicles available. From April 2027, the government will bring unused pension pots within the IHT framework. This creates an important planning window in 2026: consider whether your current pension drawdown strategy is optimal, whether to take more pension income now (leaving other assets to grow), and whether a pension trust arrangement is appropriate. Take independent financial advice before making significant changes.

Life Insurance Written in Trust: The Often-Forgotten Strategy

A whole-of-life insurance policy written in trust sits outside your estate — the payout goes directly to your beneficiaries without forming part of your estate and without going through probate. This means: no 40% IHT on the payout, faster payment (bypasses probate which can take months or years), and the funds are available immediately to pay the IHT bill on the rest of the estate. Writing a policy in trust is free of charge and takes 15–20 minutes. It does not affect your premiums. Most people with life insurance policies have never done this — ask your insurer for a trust deed form.

Frequently Asked Questions

How can I avoid inheritance tax legally in the UK?

Legal IHT reduction strategies include: making gifts during your lifetime (£3,000/year annual exemption, gifts out of income), contributing to pensions (outside your estate), writing life insurance in trust, using trusts for wealth transfer, leaving assets to your spouse (exempt), donating to charity (reduces IHT to 36% if 10%+ of estate), and using business or agricultural property relief if you own qualifying assets.

Do pensions avoid inheritance tax in the UK?

Currently (2026), defined contribution pension pots are outside your estate for IHT purposes — making them one of the most tax-efficient assets to pass on. However, from April 2027, the government has announced that unused pension pots will be brought within the IHT net. This makes urgent pension planning decisions important in 2026 — consider whether to take pension income now or leave the pot to grow.

What is the nil-rate band for inheritance tax UK 2026?

The IHT nil-rate band (NRB) is £325,000 per person for 2026-27 — frozen until 2031. Married couples and civil partners can combine allowances, giving up to £650,000. If the family home is left to direct descendants, the Residence Nil-Rate Band (RNRB) adds up to £175,000 per person (£350,000 per couple) — bringing the potential combined threshold to £1 million.

Does giving to charity reduce inheritance tax?

Yes — two ways. First, gifts to UK-registered charities are completely exempt from IHT. Second, if you leave at least 10% of your 'net estate' (the chargeable estate after deducting the nil-rate band) to charity, the IHT rate on the rest of your estate is reduced from 40% to 36%.

What is business property relief for IHT?

Business Property Relief (BPR) provides 50–100% relief from IHT on qualifying business assets. Unincorporated businesses and shares in unquoted companies qualify for 100% relief. Shares in AIM-listed companies previously qualified for 100% BPR, but from April 2026, this has been restricted to 50% relief — an important change for investors holding AIM shares as an IHT planning strategy.
