With the right planning, many UK families can dramatically reduce — or even eliminate — their Inheritance Tax bill. Here’s how.
Every year, thousands of ordinary UK families are hit with an unexpected and entirely avoidable tax bill. Inheritance Tax — charged at a brutal 40% on estates above a set threshold — raised a record £7.5 billion for the Government in the 2023/24 tax year alone. And with house prices increasing across the country, more and more families are being dragged into the IHT net.
Quick Facts: What You Need to Know
Before we dive in, here are the key numbers every family should know:gov+2
- 40% — the rate of Inheritance Tax charged on everything above your allowance
- £325,000 — the Nil Rate Band (NRB): the tax-free allowance every individual gets
- £175,000 — the Residence Nil Rate Band (RNRB): an extra allowance when you leave your home to children or grandchildren
- £500,000 — the total tax-free allowance for a single person who qualifies for both bands
- £1,000,000 — what a married couple or civil partners can potentially pass on tax-free by combining their allowances
- Seven years — how long you typically need to survive after making a gift for it to fall completely outside your estate
- £3,000 — the annual gifting allowance every individual has, every tax year
- £250 — the small gift limit you can give to any number of individuals each year
- Spouse exemption — assets passed between spouses or civil partners are completely free of IHT
1. Gifting During Your Lifetime
One of the simplest strategies is also the most overlooked: give money away while you’re alive.
Every individual can give away up to £3,000 per year completely free of IHT — that’s £6,000 for a couple. If you didn’t use last year’s allowance, you can carry it forward for one year only, meaning a couple could give away up to £12,000 in a single tax year.
You can also give £250 to as many different people as you like each year, with no IHT implications. Wedding gifts have their own special allowances too: £5,000 to a child, £2,500 to a grandchild, and £1,000 to anyone else.
What about larger gifts? Bigger gifts are treated as Potentially Exempt Transfers (PETs). This means if you survive for seven years after making the gift, it falls completely out of your estate. Die within seven years and IHT may still be due — but at a tapered rate the closer you get to seven years.
Example: A grandparent gives £50,000 to their adult grandchild today. If they survive seven years, that £50,000 is entirely outside the estate. Not a penny of IHT to pay on it.
2. Gifts From Surplus Income
This is one of the most powerful IHT exemptions in the UK tax code — and most people have never heard of it.
If you regularly give money away from your income (not your savings), those gifts can be completely exempt from IHT — immediately, with no seven-year wait.
To qualify, three conditions must be met:
- The gifts must form part of your normal expenditure (regular, not one-off)
- They must come from income, not capital or savings
- They must not reduce your standard of living
This can be remarkably powerful for retirees with a good pension, rental income, or investment income that exceeds their day-to-day needs. Someone giving away £1,000 per month from a surplus pension could remove £12,000 a year from their estate — completely exempt from IHT, year after year.
The golden rule: keep records. HMRC will want evidence that the gifts were regular, came from income, and didn’t affect your lifestyle.
3. Using Trusts: Protection and control
If you want to move money out of your estate but aren’t ready to hand a large cash lump sum to a younger relative, a Trust might be the answer. Think of a trust as a “separate entity” where you place assets for someone else to look after until the time is right.
The Nil Rate Band (NRB) Trust
This is a classic strategy used to “lock in” your £325,000 tax-free allowance.
- How it works: Instead of leaving everything to a spouse (which is tax-free but can make the survivor’s estate very large), you leave an amount up to the £325,000 limit into a trust when the first partner passes away.
- The Benefit: The assets in that trust—and any future growth on them—are technically outside the surviving spouse’s estate. If that £325,000 grows to £500,000 over ten years, that extra £175,000 of growth is completely shielded from the 40% tax man.
The Loan Trust: Keep the capital, give away the growth
A Loan Trust is perfect for those who want to reduce their tax bill but are worried they might need their money back one day.
- How it works: You “loan” a sum of money (say £100,000) to a trust rather than gifting it. Because it is a loan, you can demand the original £100,000 back at any time.
- The Benefit Any investment growth on that money belongs to the trust, not you.
- The Result: The growth is immediately outside your estate. It’s a way to “freeze” the value of your assets while your heirs benefit from the future upside.
Bare Trusts: Simple and Direct
These are the most basic types of trusts, often used for children’s savings.
- How it works: Assets are held by trustees (usually parents) for a beneficiary. Once the child turns 18 (or 16 in Scotland), they have an absolute right to the money.
- The Benefit: It is treated as a “Potentially Exempt Transfer,” meaning if you live for 7 years, the whole amount is tax-free.
Discretionary Trusts: The Ultimate Control
If you have a large family or are worried about how a beneficiary might spend their inheritance, this gives you maximum flexibility.
- How it works: The trustees have the power to decide who gets what and when. No single beneficiary has a right to the assets.
- The Benefit: It protects assets from being “lost” to a beneficiary’s divorce, bankruptcy, or poor spending habits.
Interest in Possession Trusts: Providing an Income
Commonly used in “second marriage” scenarios to protect both a spouse and children.
- How it works: A beneficiary (often a surviving spouse) is given the right to the income (or the right to live in a house) for the rest of their life.
- The Benefit: When they pass away, the capital is then passed automatically to the “remainderman” (usually your children).
Trusts come with their own tax rules — including potential charges every ten years and on exit — and the law in this area is genuinely complex. Always take professional advice before setting one up.
4. Life Assurance Written in Trust
Here’s a practical solution many families overlook: you can’t always avoid IHT, but you can plan to pay it without forcing your your beneficiaries to sell assets quickly.
A whole-of-life insurance policy pays out a lump sum on death. If that policy is written in trust, the payout goes directly to your beneficiaries — it doesn’t form part of your estate, so it isn’t taxed itself.
The proceeds can then be used to settle the IHT bill immediately, without your children having to sell the family home, a business, or an investment portfolio under time pressure.
Example: A couple calculate they’ll have an IHT bill of roughly £80,000. They take out a joint whole-of-life policy for £80,000, written in trust for their children. The premium is a manageable monthly sum. When the second partner dies, the policy pays out directly to the children — who use it to settle the tax bill in full.
5. The Residence Nil Rate Band
The Residence Nil Rate Band (RNRB) is worth up to £175,000 per person — potentially £350,000 for a couple. But it only applies when you leave your main home to a direct descendant — a child, stepchild, adopted child, or grandchild.
Combined with the standard NRB, this gives a single person a £500,000 tax-free allowance, and a couple up to £1,000,000.
What If You’ve Downsized?
Many people worry that selling their home and moving to a smaller property — or into care — means losing this allowance. The good news is that downsizing provisions protect your entitlement.
Even if you’ve sold your home, moved somewhere smaller, or moved into a care home, your estate may still claim the RNRB — provided equivalent assets (of the same value as the “lost” allowance) pass to direct descendants. There is no time limit: the downsizing can have happened years before death.
Keep records. HMRC requires detailed evidence of the original property, its value, and what happened to the proceeds.
Watch Out: The £2 Million Taper
The RNRB starts to taper away once your estate exceeds £2 million — at the rate of £1 for every £2 above that threshold. At £2.35 million, the RNRB disappears entirely for a single person. This makes planning even more critical for larger estates.
6. Investing for Your Family: Business Relief (BR)
If you have spare capital and don’t want to give it away yet, Business Relief (BR) is one of the most effective ways to “shelter” money from Inheritance Tax without losing access to it.
Historically, this was used to prevent family businesses from being broken up to pay tax bills. Today, ordinary investors can use it too.
How it Works: The “Two-Year” Rule
Unlike the 7-year rule for gifts, most BR-qualifying investments only need to be held for two years to become eligible for relief. If you hold them at the time of your death, they can be passed on with significant tax savings.
The New 2026 Rules
As of April 2026, the rules have changed to focus on helping smaller estates:
- 100% Relief on the First £2.5 Million: You (and your spouse) each have a £2.5 million allowance. Any qualifying business assets up to this amount can be passed on completely tax-free.
- 50% Relief on the Excess: If your business assets are worth more than £2.5 million, the amount above the limit gets 50% relief. This means you only pay an effective tax rate of 20% on that extra portion.
- Transferable Allowance: Just like the Nil Rate Band, any unused part of this £2.5 million can be passed to a surviving spouse, giving couples a potential £5 million shield for business assets.
AIM Shares: The 2026 Change
Many people use AIM (Alternative Investment Market) shares inside an ISA to get IHT relief.
- Before 2026: These could often be 100% tax-free.
- Now: From April 2026, all AIM shares receive a flat 50% relief. This means they are effectively taxed at 20% upon death, regardless of whether you are under the £2.5 million cap.
Note: Business Relief is “high risk.” You are investing in smaller or unquoted companies that can be volatile. This is a strategy for those who are comfortable with investment risk in exchange for the tax benefit.
Example: A Couple With a £1.2 Million Estate
Let’s put it all together with a simple, realistic example.
Starting position:
| Asset | Value |
|---|---|
| Family home | £700,000 |
| Pension, Investments and savings | £500,000 |
| Total estate | £1,200,000 |
Without planning:
Assuming both partners have died and both sets of allowances (£650,000 NRB + £350,000 RNRB) are claimed, the combined tax-free allowance is £1,000,000.pricemann+1
- Taxable estate: £1,200,000 − £1,000,000 = £200,000
- IHT bill: £200,000 × 40% = £80,000
With planning — gifting £200,000 over time:
If the couple gift £200,000 to children over the years (using annual allowances, PETs, or income gifts), the estate reduces to £1,000,000.
- Taxable estate: £1,000,000 − £1,000,000 = £0
- IHT bill: £0
Alternatively, if they cannot gift that sum but take out a whole-of-life policy for £80,000 written in trust, their heirs receive the full payout tax-free to settle the bill — with no assets needing to be sold.
Action Plan: Do This Now
- Work out the value of your estate — home, savings, investments, life policies, pension death benefits, and any other assets
- Check your allowances — how much NRB and RNRB is available to you, and whether your spouse’s unused allowance can be transferred
- Start annual gifting early — use your £3,000 allowance every year; carry forward any unused amount from the previous year
- Track gifts from income carefully — keep a simple spreadsheet or letter each tax year documenting regular income gifts
- Consider life insurance in trust — if a tax bill is likely, a whole-of-life policy written in trust can protect your heirs from a rushed asset sale
- Review every few years — your estate value, personal circumstances, and the tax rules all change over time
Warning: What to Watch Out For
- Seven-year rule — gifts made within seven years of death can still attract IHT. Taper relief helps, but doesn’t eliminate the risk.
- Loss of control — once an asset is given away, it’s gone. You can’t take it back if circumstances change
- Trust complexity — trusts have their own periodic and exit charges; they are not a “set and forget” solution
- The £2 million taper — larger estates lose the RNRB above this threshold, making planning even more important
- Poor record-keeping for income gifts — without clear records, HMRC can challenge whether gifts truly came from surplus income
- Deprivation of assets rules — if gifts are made primarily to avoid care home fees rather than IHT, local authorities may still take them into account
