UK Inheritance Tax 2026: Thresholds & How to Reduce It

The two thresholds that shield most estates

Every person in the UK gets a nil-rate band of £325,000 — the amount of their estate that passes tax-free. It's been frozen at that figure since 2009, and the freeze runs until 2030, which quietly means house price inflation keeps dragging more estates into tax every year.

On top of that, the residence nil-rate band adds £175,000, but only when three conditions are met: the estate includes a home, the home passes to direct descendants (children, grandchildren, stepchildren), and the total estate is under £2 million (it tapers above that). Meet all three and a single person's tax-free total is £500,000.

For a married couple or civil partners who leave everything to each other, unused allowances transfer to the surviving partner. Two full nil-rate bands (£650,000) plus two residence bands (£350,000) means a couple can pass on £1 million before a penny of inheritance tax is due — as long as the family home goes to the children.

Margaret's £600,000 estate, line by line

Back to Margaret. She was widowed, so she inherited her husband's unused nil-rate band — but let's walk through her estate as a single person's to show the mechanics clearly:

1. Total estate: £600,000 (house £460,000 + savings £110,000 + belongings £30,000) 2. Nil-rate band: £325,000 at 0% → £0 tax 3. Residence nil-rate band: her home passes to her children → £175,000 at 0% → £0 tax 4. Tax-free total: £500,000 5. Taxable amount: £600,000 − £500,000 = £100,000 6. Inheritance tax at 40%: £40,000

Her children split £560,000 between them. The effective tax rate on the whole estate was 6.7%, not 40% — because the headline rate only applies above the thresholds.

One detail worth knowing: if Margaret had left 10% of her net estate to charity, the rate on the rest would have dropped from 40% to 36%. Charitable bequests reduce the bill twice — the gift itself is exempt, and the rate falls.

Run your own figures through the UK Inheritance Tax (IHT) & Nil-Rate Band Calculator to see exactly where your estate sits against the two bands.

The 7-year rule: how gifts escape tax

Gifts you make during your lifetime are potentially exempt transfers (PETs). Survive seven years after making one and it's completely outside your estate — no tax at all. Die within seven years and the gift is added back, with taper relief reducing the tax on a sliding scale:

• Death within 3 years: 40% on the gift
• 3–4 years: 32%
• 4–5 years: 24%
• 5–6 years: 16%
• 6–7 years: 8%
• After 7 years: 0%

Two common misunderstandings. First, taper relief only reduces the tax rate on the gift, not the gift's value — and it only helps once the gift itself exceeds the nil-rate band. Second, the £3,000 annual gift allowance is separate: you can give away £3,000 each tax year with no 7-year clock at all, plus unlimited small gifts of £250 per person, plus £5,000 to a child on their wedding day.

The traps that catch families

The gift with reservation rule is the big one. Give your house to your children but keep living in it rent-free, and HMRC treats the gift as never having happened. It stays in your estate. The only clean ways round it: move out, or pay your children a genuine market rent for the rest of your life.

Business and farm assets get reliefs of their own — up to 100% on qualifying business property — but from April 2026 the first £1 million of combined agricultural and business assets keeps full relief and anything above gets 50%. If the family wealth is a farm or a company, this changed recently and deserves fresh advice.

And watch the pension change coming in April 2027: unspent pension pots will count inside estates for inheritance tax. Right now they're outside it, which made pensions a popular IHT shelter. That shelter is closing — another reason to review plans before the deadline.

What actually reduces the bill

In order of how much they usually save:

Use both spouses' bands. The single biggest lever for couples is making sure the first death's allowances transfer. If the first partner left everything to the survivor, both nil-rate bands and both residence bands survive. A will review after the first death is essential.

Gift early, gift often. The 7-year clock rewards early action. A £100,000 gift to a child at 60 that survives to 67 saves £40,000 of tax. The same gift at 76 is a gamble.

Write life insurance in trust. A £200,000 life policy written in trust sits outside your estate and — crucially — pays out quickly, giving your family cash to settle the tax bill before probate. Without it, families sometimes have to sell the house to pay HMRC.

Spend the tax-free bits. Pensions (drawn before 2027), ISAs (transferable to a spouse), and the annual gift allowances are all use-it-or-lose-it. A couple giving £6,000 a year for 20 years moves £120,000 out of their estate with zero risk.

Dying without a will: intestacy

Everything above assumes a valid will exists. Without one, the intestacy rules decide who gets what — and they don't care about your wishes. A surviving spouse gets the first £322,000 of the estate plus personal belongings, then half of the remainder; the children split the other half. An unmarried partner gets nothing automatically, however long you've been together.

Intestacy also wastes allowances. The residence nil-rate band needs the home to pass to direct descendants — intestacy usually achieves that for children, but for unmarried couples or blended families it can easily fail. A will costs £150–£300 and takes an afternoon. Dying without one costs your family months of probate delays and potentially tens of thousands in lost allowances. There is no cheaper financial product in existence.

The verdict: should you worry?

If your estate is under £500,000 as an individual (or £1 million as a couple with a home going to the kids), inheritance tax is mostly a paperwork exercise — valuations, probate, and filing, but little or no tax. Between those figures and about £750,000, simple steps like the 7-year gifts and a charity bequest usually handle it. Above that, or where the wealth sits in a business, a farm, or overseas assets, professional advice pays for itself many times over.

The frozen thresholds are the silent story: £325,000 hasn't moved since 2009 while average house prices have roughly doubled. More families are being pulled in every year without any law changing. Check where you stand now rather than assuming you're below the line.
