Inheritance Tax Planning in the UK: How to Protect Your Estate in 2026

If you own a home in Barnsley, Sheffield, or anywhere in England and Wales, the question is no longer "will my estate pay inheritance tax?" but "how much, and what can I do about it now?"

This guide walks you through the 2026 thresholds, the changes coming in 2027, and the practical planning steps a qualified estate planning solicitor can take on your behalf.

What is inheritance tax and who pays it?

Inheritance tax (IHT) is a 40% charge on the value of your estate — your property, savings, investments and possessions, minus debts — above certain tax-free thresholds. It is paid by your executors out of the estate before your beneficiaries receive their share.

Two allowances form the foundation of the system:

•Nil Rate Band (NRB): £325,000 per person, available against any asset.

•Residence Nil Rate Band (RNRB): £175,000 per person, available when a qualifying main residence is left to direct descendants (children, grandchildren, stepchildren).

A married couple or civil partnership can combine and transfer these allowances, giving a potential £1 million tax-free threshold when a qualifying home passes to lineal heirs. The standard rate above the threshold is 40%, reduced to 36% if at least 10% of the net estate is left to charity.

The 2026 inheritance tax landscape — what has changed

The November 2025 Autumn Budget extended the freeze on the NRB, the RNRB and the £2 million taper threshold until 5 April 2031. With UK house prices having roughly doubled since the £325,000 NRB was set in April 2009, this fiscal drag is quietly drawing tens of thousands of additional estates into taxable territory every year.

Trust Registration Service data shows 121,000 new trusts were registered in 2024–25 alone, taking the UK total to 835,000 — clear evidence that families are responding to the freeze with proactive trust-based planning.

The single biggest change ahead is the inclusion of pensions in IHT. Finance Act 2026 received Royal Assent on 18 March 2026, and from 6 April 2027, most unused pension funds and pension death benefits will form part of the deceased's estate for IHT purposes. Pensions left to a spouse or civil partner remain exempt, but those passing to children or grandchildren could be hit twice — by IHT at 40% and, if death occurs after age 75, by income tax on withdrawals.

Who is most at risk in 2026?

You are likely to need active inheritance tax planning if any of the following apply:

•You own a home worth more than £400,000, especially in the South East, London commuter belt, or any area where prices have outpaced the threshold freeze.

•Your combined estate (including pension pots) is approaching or exceeds £500,000 as a single person, or £1 million as a couple.

•You own a business, shares in a private company, or AIM-listed investments — reliefs in this area are also under reform.

•You plan to leave assets to anyone other than a spouse or civil partner, such as unmarried partners, children from a previous relationship, or charities.

•You have a pension pot you intended to pass on tax-efficiently — the 2027 changes will substantially alter your options.

Seven practical inheritance tax planning strategies

A qualified estate planning solicitor can combine several of the following tools into a coordinated plan tailored to your family circumstances.

1. Make or update your will. An outdated will is the single most common cause of unintended IHT exposure. Reviewing your will every three to five years — or after any major life event — ensures it reflects current allowances, family structure and the 2027 pension rules.

2. Use a deed of trust or declaration of trust. Placing assets such as a share of the family home into a properly drafted trust can ring-fence value from future care fees and direct it to chosen beneficiaries. Trusts are not a tax-avoidance gimmick; they are an HMRC-recognised tool used by 835,000 UK families.

3. Protective Property Trusts (PPTs). For married couples, a PPT in each partner's will protects their share of the home from being absorbed into the survivor's estate, helping preserve both nil rate bands and shielding against later care costs.

4. Life Insurance written into trust. A life policy written in trust pays out outside the estate, providing liquidity to settle any IHT bill within the six-month HMRC deadline without forcing a property sale.

5. Lifetime gifts and the seven-year rule. Gifts made more than seven years before death generally fall outside the estate. Annual exemptions (£3,000 per year, plus small gifts and gifts from surplus income) can also reduce taxable value significantly over time.

6. Lasting Powers of Attorney (LPAs). A registered LPA does not directly cut IHT, but without one, a family can lose years of planning capacity if a person loses mental capacity. Both Property & Financial Affairs and Health & Welfare LPAs should be registered.

7. Pension review before April 2027. With unused pension funds entering the IHT net, families need to revisit drawdown strategies, expression-of-wish forms, and the order in which different assets are spent. Many people will be better off drawing from their pension earlier and preserving other assets, but the right answer depends on age, health, income needs and beneficiaries. A coordinated review with your solicitor and financial adviser, ideally before the 2027 start date, is now essential to avoid being caught by the new rules without a plan in place.

Why work with an estate planning solicitor rather than a will-writing service?

Online will-writing services are convenient for the simplest cases, but inheritance tax planning is rarely simple. A solicitor regulated by the SRA is accountable for the advice given, insured against errors, and trained to coordinate wills, trusts, LPAs and tax planning as a single strategy.
