Inheritance tax tips for UK estates: 2026 guide

Hands sorting UK inheritance tax documents on desk

TL;DR:

  • Inheritance tax charges 40% on estates above the tax-free threshold, which can be reduced through planning.
  • Using allowances, exemptions, gifting strategies, and reliefs can significantly lower the tax bill before 2027 legislative changes.

Inheritance tax (IHT) is a tax charged on the value of your estate above a set tax-free threshold when you die. The standard rate is 40%, and with property values rising across the UK, more families find themselves caught in the IHT net than ever before. The good news is that the law provides a range of legitimate inheritance tax tips, strategies, and exemptions that can significantly reduce what HMRC takes from your estate. This guide covers the most effective approaches for 2026, including critical changes coming in april 2027 that every estate planner needs to know about now.

1. Understand your inheritance tax allowances first

The foundation of any effective IHT strategy is knowing exactly how much you can pass on tax-free. For the 2026/27 tax year, the Nil Rate Band is £325,000 and the Residence Nil Rate Band (RNRB) is £175,000. Together, these give an individual a total tax-free threshold of £500,000, provided the main home passes to direct descendants such as children or grandchildren.

Married couples and civil partners can combine their allowances. This means a couple can pass up to £1,000,000 to their children entirely free of IHT. That is a significant planning advantage that many families do not fully use.

The Nil Rate Band is frozen until at least april 2031. That freeze effectively increases the proportion of estates subject to IHT each year as property and asset values rise. Knowing this makes early planning more urgent, not less.

  • The Nil Rate Band: £325,000 per person
  • The Residence Nil Rate Band: £175,000 per person (direct descendants only)
  • Combined couple allowance: up to £1,000,000
  • RNRB tapers away for estates above £2,000,000

Pro Tip: If your estate is close to the £2,000,000 threshold, the RNRB starts to reduce by £1 for every £2 above that figure. Gifting assets before death can bring your estate below this threshold and preserve the full RNRB.

2. Use the spouse exemption fully

Transfers between spouses and civil partners are fully exempt from IHT, regardless of the amount. This is the most straightforward IHT reduction tool available, and it requires no forms or applications. Both parties must be UK-domiciled or long-term UK residents for the exemption to apply in full.

Crucially, any unused Nil Rate Band or Residence Nil Rate Band from the first spouse to die transfers automatically to the surviving spouse. This is what allows couples to reach the £1,000,000 combined threshold. You do not need to claim this during the first death, but the executors of the surviving spouse’s estate must make the claim when the time comes.

If you are separated or divorced, this exemption no longer applies. Signaturelaw advises clients going through separation to review their inheritance planning after divorce as a matter of priority, since the tax consequences can be significant.

3. Make use of annual gift exemptions

Every individual can give away £3,000 per tax year completely free of IHT. This is called the annual gift exemption. If you did not use it last year, you can carry it forward once, allowing a gift of up to £6,000 in a single year.

In addition, the small gift exemption allows you to give up to £250 to any number of recipients each year, with no IHT consequence. You cannot combine the £250 exemption with the £3,000 allowance for the same person, but you can use both for different recipients.

Wedding and civil partnership gifts also carry their own exemptions: £5,000 from a parent, £2,500 from a grandparent, and £1,000 from anyone else. These exemptions are per event, not per year, and the gift must be made before or on the day of the ceremony.

4. Understand Potentially Exempt Transfers and the 7-year rule

A Potentially Exempt Transfer (PET) is any gift you make to another individual above the annual exemptions. The gift becomes fully exempt from IHT if you survive for seven years after making it. If you die within seven years, the gift may be brought back into your estate for IHT purposes.

Taper relief reduces the tax charge on gifts made between three and seven years before death. The tax rate reduces progressively: gifts made three to four years before death attract 32%, reducing to 8% for gifts made six to seven years before death, and 0% after seven years.

One important detail that many people miss: taper relief only applies once the total value of gifts exceeds the Nil Rate Band. If your gifts are smaller than £325,000, taper relief does not reduce your tax bill at all. Gifts are offset against the Nil Rate Band starting with the earliest gifts first.

  1. Make the gift as early as possible to start the seven-year clock.
  2. Keep a written record of every gift, including the date, amount, and recipient.
  3. Do not assume taper relief will help if your total gifts are below £325,000.
  4. Consider life insurance written in trust to cover any potential IHT liability during the seven-year period.

Pro Tip: HMRC can challenge gifts if records are poor. Keep a simple spreadsheet or letter confirming each gift. Your executors will thank you, and it protects your beneficiaries from unexpected tax bills.

5. Use regular gifts from surplus income

This is one of the most underused and powerful exemptions in UK tax law. Regular gifts out of surplus income are immediately exempt from IHT, with no seven-year wait required. The gifts must be habitual, made from income rather than capital, and must not reduce your own standard of living.

This exemption can cover school fees paid for grandchildren, monthly contributions to a family member’s savings account, or life insurance premiums paid on behalf of a child. The key is that the payments are regular and documented.

HMRC requires clear evidence that the gifts come from surplus income. You should keep records showing your annual income, your normal expenditure, and how the gifts fit within what remains. A simple annual summary prepared each april is sufficient for most estates.

6. Explore Business Property Relief and Agricultural Property Relief

Business Property Relief (BPR) and Agricultural Property Relief (APR) can reduce the IHT value of qualifying assets significantly. Historically, both reliefs offered 100% exemption on qualifying assets. From 6 april 2026, a combined 100% relief cap of £2,500,000 per person applies. Value above this cap receives 50% relief rather than full exemption.

The cap is transferable between spouses, giving couples a combined threshold of £5,000,000 before the 50% rate applies. This is still a substantial relief, but farming families and business owners with larger asset values need to plan carefully.

Relief type Qualifying assets Relief rate (up to £2.5m) Relief rate (above £2.5m)
Business Property Relief Unlisted shares, trading businesses, AIM shares 100% 50%
Agricultural Property Relief Farmland, farm buildings, certain farmhouses 100% 50%

AIM-listed shares also qualify for BPR at 50% relief above the cap. Agricultural relief must be applied before business relief where both apply to the same asset, and the caps apply proportionally across all qualifying assets.

7. Donate to charity to reduce your IHT rate

Leaving at least 10% of your net estate to a UK-registered charity reduces your IHT rate from 40% to 36%. The net estate is calculated after deducting the Nil Rate Band and other exemptions. This means the charitable gift effectively costs less than it appears, because the tax saving offsets part of the donation.

For example, if your taxable estate is £500,000, a donation of £50,000 to charity reduces the IHT rate on the remaining £450,000 from 40% to 36%. The tax saving on the lower rate partially compensates for the charitable gift. Many estate planners find this an appealing way to support causes they care about while reducing the overall tax burden on their family.

8. Write life insurance policies in trust

A life insurance policy written in trust passes outside your estate and does not add to the value subject to IHT. The payout goes directly to your named beneficiaries without going through probate, which also means faster access to funds. This does not reduce the IHT bill itself, but it provides the liquidity your family needs to pay it without selling assets under pressure.

Policies not written in trust form part of your estate and attract IHT at 40%. The difference in outcome for your beneficiaries can be substantial. Setting up a trust around an existing policy is straightforward and does not require a solicitor in every case, though professional advice is recommended for larger policies.

9. Check who inherits your main home

The Residence Nil Rate Band only applies when your main home passes to direct descendants. Direct descendants include children, stepchildren, adopted children, and grandchildren. Leaving your property to a sibling, a friend, or a non-direct relative disqualifies the RNRB entirely, adding up to £175,000 back into your taxable estate.

This is a common and costly mistake. If your current will leaves your home to someone who is not a direct descendant, you should review it now. A straightforward amendment to your will can preserve this allowance and save your estate up to £70,000 in tax. Signaturelaw’s guide on how to write a will explains how to structure beneficiary arrangements correctly.

10. Plan now for the April 2027 pension changes

This is the most significant IHT change in a generation. From 6 april 2027, many unused pension funds and death benefits will be included in your estate for IHT purposes. Currently, pension pots sit entirely outside the estate, making them a popular tool for passing wealth to the next generation tax-efficiently.

The change means that estates with large pension funds could face a substantially higher IHT bill than they currently anticipate. Pension death-in-service benefits may remain excluded, but this is subject to confirmation from HMRC.

  • Review the size of your pension pot and how it affects your total estate value.
  • Consider drawing down pension funds earlier and gifting surplus income to reduce the estate.
  • Reassess existing wills and gifting plans in light of the new rules.
  • Seek professional advice before april 2027 to restructure where possible.
  • Do not assume your current estate plan remains optimal after the change.

Estate planning should anticipate the pension inclusion by reassessing other assets and gifting strategies now. Waiting until 2027 leaves little time to act, particularly given the seven-year rule on PETs.

Key takeaways

What I have learned about inheritance tax planning after years of estate work

Most people treat inheritance tax as something to deal with later. That instinct is understandable. Nobody wants to think about their own death, and the rules feel complicated. But the cost of delay is real and measurable.

The single most underrated strategy I see overlooked is the regular gifts from surplus income exemption. Families focus on the annual £3,000 allowance and the seven-year rule, but they miss the fact that consistent, documented gifts from income carry no seven-year risk at all. A grandparent paying school fees regularly, or a parent contributing monthly to a child’s savings, can move substantial wealth out of the estate with no IHT exposure whatsoever. The only requirement is good record-keeping, and yet most families never do it.

The upcoming pension changes also concern me more than most people realise. Pension pots have been used for decades as a clean way to pass wealth outside the estate. From april 2027, that changes. Estates that look manageable today could face a very different picture in two years. The time to review is now, not when the rules have already changed.

My honest view is that no single strategy is enough on its own. The families who protect the most wealth are the ones who combine allowances, gifting, reliefs, and professional advice into a consistent plan reviewed every few years. Signaturelaw’s estate planning guide for UK families is a good starting point if you want to understand how these strategies fit together.

FAQ

What is the inheritance tax threshold in the UK for 2026?

The standard Nil Rate Band is £325,000 per person. With the Residence Nil Rate Band of £175,000, individuals can pass up to £500,000 tax-free, and couples up to £1,000,000, provided the main home passes to direct descendants.

How does the 7-year rule work for gifts?

Gifts made to individuals become fully exempt from IHT if you survive seven years after making them. Taper relief reduces the tax rate on gifts made between three and seven years before death, but only where total gifts exceed the Nil Rate Band.

Will my pension be subject to inheritance tax?

Currently, pension funds sit outside your estate for IHT purposes. From 6 april 2027, many unused pension funds and death benefits will be included in the estate, making early planning essential for those with significant pension savings.

Does leaving money to charity reduce inheritance tax?

Leaving at least 10% of your net estate to a UK-registered charity reduces the IHT rate from 40% to 36% on the remainder of the taxable estate, which can result in a meaningful overall saving.

What happens if I leave my home to someone who is not a direct descendant?

The Residence Nil Rate Band of £175,000 does not apply. Your estate loses this allowance entirely, which could increase the IHT bill by up to £70,000. Reviewing your will to name direct descendants as beneficiaries of the property resolves this.
