Understanding Inheritance Tax: Essential Planning Strategies for Larger Estates

Most people who own a larger estate already know inheritance tax is coming for it. What stops them acting isn’t apathy. It’s the sense that the rules are impenetrable, and that doing anything about them means clever financial footwork they’d rather not risk.

The good news is that the most effective inheritance tax planning strategies are not exotic. They’re ordinary, they’re written into the legislation on purpose, and they mostly come down to knowing what counts, when to act, and what paperwork to keep.

A Quick Recap: Where the Inheritance Tax Thresholds Stand (2026/27)

The standard nil-rate band is £325,000. It has been frozen at that figure since 2009, and the 2024 Autumn Budget confirmed the freeze runs until April 2030.

Leave a qualifying home to your children or grandchildren and you may also get the residence nil-rate band of £175,000. A married couple or civil partners who combine and transfer both allowances can shelter up to £1 million. Anything above your available threshold is taxed at 40%.

That standard band hasn’t moved since 2009. The residence band has sat at £175,000 since 2020. Property prices have not been so obliging. The result is that families who’d never describe themselves as wealthy, particularly homeowners in the south of England, are now squarely inside the net. If you want the basics first, start with our beginner’s guide to inheritance tax.

Strategy 1: Regular Gifts from Income

Ask most people about gifting and they’ll mention the £3,000 annual exemption or the seven-year rule. Those are covered in our guide on common mistakes to avoid. But if you have a good salary or a comfortable pension, the most powerful exemption in the UK tax system is one almost nobody uses: normal expenditure out of income.

Under Section 21 of the Inheritance Tax Act 1984, a gift is exempt immediately. No seven-year wait, no taper, nothing. You just have to satisfy three tests:

• The gift was part of a normal, habitual pattern of giving.
• It came out of surplus income, not capital.
• You were left with enough income to maintain your usual standard of living, without cutting back or dipping into savings.

Income vs Capital: The Distinction That Decides It

Everything turns on how the money is classified. Income means your net salary, profits from a trading business, net rental income, UK dividends and contractual pension payments. Capital means savings accounts, the proceeds of selling shares or property, and anything sitting in an ISA.

Take £10,000 out of a savings account and give it to your child, and it’s a capital gift on the seven-year clock. Give them £10,000 that accumulated in your current account from monthly pension payments, and it can be exempt from the moment it lands.

The rule scales well. Paying a grandchild’s school fees directly to the school each term qualifies. So does a standing order helping a child with their mortgage.

The Paper Trail

Here’s the catch. The exemption is claimed after your death, by your executors, who have to prove to HMRC that the gifts were regular and that you could afford them. They’ll be filling in Form IHT403, which wants a year-by-year breakdown of your net income against your actual living costs.

What to do: don’t make these gifts in random amounts whenever it occurs to you. Set up a standing order, label it something unambiguous like “Monthly Allowance out of Surplus Income”, and keep a running spreadsheet of income against household spending.

You’re building evidence for someone who will never get to ask you what you meant.

Strategy 2: Business Property Relief and Agricultural Property Relief

If you own a business, a share of a partnership, or farmland, two reliefs matter more than anything else: Business Property Relief (BPR) and Agricultural Property Relief (APR). For decades they let qualifying businesses and farms pass down tax-free. The 2024 Autumn Budget changed that, and after the allowance was raised in December 2025 the new rules took effect on 6 April 2026.

What Still Qualifies

BPR reduces the value of qualifying business assets for IHT. How much depends on what you own and how:

• 100% relief: a sole trader business, an active interest in a partnership, or shares in an unquoted trading company. Since 6 April 2026 this rate applies only up to the £2.5 million allowance described below.
• 50% relief: controlling shareholdings in a fully listed company, or land, buildings and machinery you own personally but which are used by a business you control or are a partner in. Since 6 April 2026 this also covers shares not listed on a recognised stock exchange, most significantly those quoted on AIM. Those attract 50% relief in every case and don’t draw on the £2.5 million allowance at all.

You must have owned the asset for at least two years before death. The company also has to be genuinely trading. If it mainly holds investments, deals in land, or manages a share portfolio, it counts as an investment company and gets nothing. APR works on similar lines for agricultural land, pasture, woodland, farmhouses and farm buildings.

The £2.5 Million Allowance

This is the change that matters. Combined BPR and APR now share a £2.5 million allowance per person, or £5 million for a couple.

Below £2.5 million, full 100% relief still applies. Above it, relief halves to 50%. Since IHT is charged at 40%, halving the relief means business and farming wealth above £2.5 million is effectively taxed at 20%.

Picture a family engineering firm worth £3 million, owned outright by one parent:

• First £2,500,000: 100% relief, taxable value £0, tax due £0.
• Remaining £500,000: 50% relief, taxable value £250,000, tax due £100,000.

Before April 2026 that business would have passed on with an IHT bill of nothing. Now the family faces £100,000 in cash, due on death, assuming the nil-rate bands are already used up by the house and savings. For the official position, see the GOV.UK Business Property Relief guidance and the statutory framework in the Finance Act on Legislation.gov.uk.

What to do: if your business or land is worth more than £2.5 million, look at the ownership structure now. Splitting shares between spouses to use two separate £2.5 million allowances, £5 million between you, or moving ownership early through lifetime gifts, can be the difference between a handover and a forced sale.

Strategy 3: Life Insurance Written in Trust

When an estate is large but illiquid, a house, private company shares, land, the hard part isn’t working out the tax. It’s finding the cash. Inheritance tax is generally due within six months of the end of the month of death, and probate rarely gets released until a good chunk of it is paid.

That’s the trap a whole-of-life policy is built for. It pays a fixed lump sum on death, whenever that comes, as long as you keep up the premiums.

There’s a mistake here that’s easy to make and expensive to fix: leaving the policy in your own name. Do that and the payout falls into your estate, inflates the taxable value, and gets taxed at 40%.

The money you bought to pay the tax bill has just increased the tax bill.

Writing It in Trust

The fix is to write the policy in trust from the start, or assign it into an absolute or discretionary trust later. That puts it legally outside your estate.

On death, the insurer pays your trustees directly. Because the trust sits outside the estate, the money reaches your beneficiaries tax-free and without waiting for probate. They get liquid cash exactly when the bill lands, which is what stops a house being sold in a hurry at a discount.

Run the numbers. Say you and your spouse have an estate of £1.5 million. After combining your standard and residence nil-rate bands, £1 million is sheltered, leaving £500,000 taxable and a bill of £200,000.

Set up a joint-life, second-death policy in trust paying out £200,000, and when the second of you dies the insurer hands your family exactly £200,000. They pass it straight to HMRC. Your £1.5 million estate arrives intact.

This doesn’t shrink the tax. It funds it from outside.

Premiums depend on age, health and lifestyle, but for someone in their fifties or sixties in good health, the total cost is usually a fraction of the bill it settles.

What to do: check any life insurance or death-in-service benefit you already hold. If it isn’t in trust, ask your provider or a solicitor for a trust deed and get it assigned.

Strategy 4: The Charitable Legacy, Where 10% Saves You 4%

Any gift to a registered UK charity in your will is completely exempt from inheritance tax. That much is well known. Less well known is what happens when you give a meaningful share.

Leave at least 10% of your net estate, meaning what’s left after all nil-rate bands, reliefs and exemptions, to charity, and the rate on the rest of your taxable estate falls from 40% to 36%. On a larger estate, that 4% applies across the whole taxable balance, which makes a substantial gift cost your family far less than you’d expect.

Here’s the arithmetic. Take an individual with a £1.5 million estate and a £500,000 allowance, the £325,000 standard band plus the £175,000 residence band, leaving £1 million taxable.

Scenario A: Nothing to Charity

• Taxable estate: £1,000,000
• Rate: 40%
• Tax due: £400,000
• Family receives: £1,500,000 − £400,000 = £1,100,000 (£600,000 of the taxable portion)

Scenario B: 10% of the Net Estate to Charity

• Charitable gift: £100,000
• Remaining taxable estate: £900,000
• Rate: 36%
• Tax due: £324,000
• Charity receives: £100,000
• Family receives: £1,500,000 − £100,000 − £324,000 = £1,076,000 (£576,000 of the taxable portion)

What That Actually Means

Scenario A leaves the family £1,100,000. Scenario B leaves them £1,076,000.

Giving £100,000 to charity cost them £24,000. The other £76,000 came out of HMRC’s share.

What to do: the wording matters more than the number. Because asset values move, your will should say “10% of my net estate as defined for inheritance tax purposes” rather than naming a cash sum. A fixed figure that turns out to be 9.4% on the day misses the 36% rate entirely.

Strategy 5: The Deed of Variation

It’s natural to assume that once someone dies, their tax position is fixed. It isn’t. A Deed of Variation lets the beneficiaries of an estate change how the assets are distributed after the death, whether the estate passed under a will or under the intestacy rules.

To work for tax purposes it has to be in writing, executed within two years of the death, and signed by every beneficiary giving something up. It also needs a declaration that it’s intended to have retrospective effect for inheritance tax and capital gains tax under Section 142 of the Inheritance Tax Act 1984, with nobody being paid to sign.

When It Earns Its Keep

This is the safety net for when a relative dies without having planned, or with a will that stopped reflecting reality years ago. Two situations come up repeatedly:

• Generation skipping. A parent dies and leaves £500,000 to their 55-year-old child, who already owns a house and has an estate of their own. Accepting it just moves the problem forward a generation and makes it bigger. A Deed of Variation lets that child redirect the £500,000 straight to their own children. The law treats it as though the grandparent had left it to the grandchildren from the start.
• Rescuing the spousal exemption. Where someone leaves assets directly to children from a first marriage and triggers an immediate bill, the beneficiaries can redirect those assets back to a surviving stepparent. That brings them under the 100% spousal exemption, defers the tax, and buys the family time to do the job properly.

One warning. A Deed of Variation is a repair, not a plan. It needs unanimous agreement from everyone giving something up, and if one sibling won’t sign, it collapses.

What to do: if you’ve inherited money you don’t need, or you’re administering an estate with an obvious structural problem, take advice quickly. The two-year clock starts on the date of death, and the drafting has to be exact.

Strategy 6: Generation Skipping and Family Investment Companies

Above roughly £2 million, gifting and insurance stop being enough on their own. At that level you’re not managing a single tax bill, you’re managing what the tax does to the same money over decades.

The Compounding Problem

Assets that pass from grandparent to parent, then parent to child, get hit with 40% at each step. A £1 million asset taxed twice over thirty years is worth a fraction of what it started as. Generation skipping, where assets pass by will or lifetime trust straight to grandchildren, breaks that loop so the wealth is taxed once instead of twice.

Family Investment Companies

A Family Investment Company is a private limited company set up to hold family wealth, typically a property portfolio or a block of investments. It’s an alternative to a discretionary trust, which is constrained by tax charges on the way in.

The parents put capital or assets in and take voting shares, keeping control of decisions, investments and dividends for life. Children or grandchildren get non-voting shares that capture future growth. The growth then accrues inside shares the younger generation already owns, rather than inflating the parents’ estates, while the parents still run the thing.

Loan Trusts and Discounted Gift Trusts

If you know you have a problem but can’t afford to hand over capital you might need later, two structures offer a middle path:

• Loan trusts. You lend money to a trust rather than giving it away. The trust invests it. You can call the loan back whenever you need it, but the growth belongs to the trust and stays outside your estate.
• Discounted gift trusts. You gift into a trust but keep a fixed income for life. HMRC values that retained income stream against your life expectancy and discounts the gift accordingly, cutting your exposure straight away.

What to do: these carry real ongoing compliance, accounting and reporting costs. SimpleLPA can put the foundation in place, a clear, legally valid will designed to solicitor standards, but FICs and discounted gift trusts need a qualified financial adviser or chartered tax specialist alongside it.

Your Inheritance Tax Planning Action Plan, by Estate Size

£500K to £1M: Get the Basics Right

At this level the money is won by not wasting allowances:

• Have a valid, current will, so intestacy never gets a say.
• Structure it so both partners use their full £325,000 nil-rate bands and £175,000 residence nil-rate bands.
• If you own your home jointly, consider a Property Protection Trust will. If the surviving partner later needs residential care, it ring-fences at least half the home’s value for your children instead of the local authority. That works because the survivor never inherits your half, so it was never theirs to be assessed on. Signing your home over to your children while you are alive is a different thing entirely and can be treated as deliberate deprivation of assets. Our guide to understanding basic wills and ppt wills covers how it works.
• Use the £3,000 annual gifting allowance and £250 small gifts to draw down cash steadily.

£1M to £2M: Start Actively Reducing

Baseline exemptions alone will leave a real bill here:

• Set up regular gifts out of surplus income, with standing orders and records from day one.
• Take out a whole-of-life policy in trust sized to the projected bill on the second death.
• Decide whether a 10% charitable legacy fits your values, and cut your rate to 36% if it does.
• Complete pension death benefit nominations. Unused pension pots are unusually tax-efficient today, but from April 2027 they come into your estate for IHT. Our breakdown of how the 2027 pension changes affect your inheritance tax explains what shifts.

£2M+: Structure It

Past £2 million, exposure accelerates because the residence nil-rate band starts to taper. For every £2 of estate value above £2 million, you lose £1 of the £175,000 band.

The taper bites on the estate at the second death. A surviving spouse holding a fully transferred allowance and an estate over £2 million triggers it, and the relief disappears entirely at £2.35 million for an individual, or £2.7 million with a transferred allowance.

• Watch the £2 million line. If you’re just over it, lifetime gifts that bring your net estate under £2 million restore the full band and can save your family up to £140,000.
• If you own a business or farm, revisit the structure now that the £2.5 million combined BPR/APR allowance applies.
• Look at Family Investment Companies, generation-skipping arrangements or discounted gift trusts to freeze growth and move wealth down the line.

Whichever tier you’re in, the first rule of inheritance tax planning is the same: start now. Most of these strategies need time to work, and a paper trail can’t be assembled in a hurry.

The One Thing to Do Today

Every strategy here rests on the same foundation: a clear, legally binding, up-to-date will.

Die without one and the intestacy rules take over. They distribute your estate by a rigid formula that takes no interest in tax efficiency at all. They can send assets to people you’d never have chosen, waste your spouse’s exemptions, lose your residence nil-rate band, and produce a bill that a basic plan would have avoided entirely.

It’s worth putting LPAs alongside it, too. A will handles what happens after you die. An LPA handles what happens if you’re still here but can’t make decisions, which is the gap most estate plans forget.

Writing a proper will doesn’t have to be expensive or grim:

• Basic Will (£10): for straightforward individual estates. More on our wills page.
• Mirror Will (£17.50): for couples with matching wishes.
• Property Protection Trust Will (£99): for shielding your home from care fees and protecting allowances.
• Crypto Will (£25): for passing on digital assets and keys safely.

Frequently Asked Questions

How much can I give away each year without paying inheritance tax?

You have a £3,000 annual exemption, and if you didn’t use last year’s you can carry it forward for one year. On top of that you can give £250 per person per tax year to as many different people as you like. And you can make unlimited regular gifts of any size out of surplus income, as long as they follow a consistent pattern and don’t dent your standard of living.

What’s the 7-year rule for inheritance tax?

A large one-off gift above your annual allowances is a Potentially Exempt Transfer. Survive seven years and it drops out of your estate completely. Die within seven years and it comes back into the calculation and can be taxed at up to 40%, though taper relief reduces the tax if you survive between three and seven years.

Can I put my house in my children’s names to avoid IHT?

Rarely, because of the Gift with Reservation of Benefit rules. If you sign the house over but carry on living there without paying full market rent, HMRC ignores the transfer and counts the whole property in your estate anyway. Gifting a home early also creates capital gains tax exposure, and risks falling foul of the deliberate deprivation of assets rules if you later need care funding.

Does a pension count towards inheritance tax?

Not at the moment. Unused pension funds can generally pass to your beneficiaries free of inheritance tax, which makes them one of the most tax-efficient places to hold wealth. That changes from April 2027, when unused pension funds come into your estate and are taxed at the standard rates.

What’s Business Property Relief?

Business Property Relief cuts the taxable value of qualifying trading business assets or unlisted company shares by 100% or 50%, provided you’ve held them for at least two years. Plan around the £2.5 million allowance for combined 100% business and agricultural relief, which leaves business wealth above that line effectively taxed at 20%. AIM-quoted shares sit outside the allowance altogether and get 50% relief in every case.

Is inheritance tax planning legal?

Yes. What’s described here is tax avoidance: using the exemptions, reliefs and allowances Parliament wrote into the legislation, for the purpose Parliament wrote them. That’s a different thing entirely from tax evasion, which means hiding assets or misstating their value to deceive HMRC.
