Nieces and nephews sit in an awkward spot under UK inheritance tax law. They are close family but HMRC does not treat them that way. The result is that estates leaving money to a niece or nephew often pay more tax than equivalent estates leaving the same money to a child, sometimes by six figures.
The rules changed materially on 6 April 2026. Business Property Relief and Agricultural Property Relief were capped for the first time, a 10-year instalment option was extended to business assets, and the interaction between all these reliefs got more complex. If your will or estate plan has not been reviewed since then, it is worth doing that now.
This guide covers every threshold and relief that matters for 2026/27, with worked examples and a specific section on what has changed for family businesses. For a broader overview of how UK inheritance tax works, see our inheritance and trust tax guide.
How HMRC Classifies Nieces and Nephews
HMRC defines direct descendants as children, grandchildren, stepchildren, adopted children, and foster children. Nieces and nephews however close the relationship are not on that list.
In practice, this means one thing: they cannot use the Residence Nil Rate Band (RNRB). That is the extra £175,000 allowance available when a home is passed to a direct descendant. Lose it, and your nil rate band drops from £500,000 to £325,000. For a widowed aunt or uncle, the difference can be as much as £700,000 in estate value sitting outside any tax-free threshold.
2026/27 IHT Thresholds at a Glance
| IHT Allowance | Amount (2026/27) | Available to Nieces / Nephews? |
|---|---|---|
| Nil Rate Band (NRB) | £325,000 | Yes |
| Residence Nil Rate Band (RNRB) | £175,000 | No — direct descendants only |
| Transferable NRB (married couples) | Up to £650,000 combined | Yes (if aunt/uncle widowed) |
| Transferable RNRB (married couples) | Up to £350,000 combined | No |
| APR/BPR 100% relief cap (per person) | £2,500,000 | Yes, if the business qualifies |
| APR/BPR 50% relief above cap | No upper limit on 50% portion | Yes — effective 20% rate |
| APR/BPR couple combined allowance | Up to £5,000,000 | Yes |
Worth knowing: Both the NRB (£325,000) and the RNRB (£175,000) are frozen until at least April 2030.
House prices are not frozen. Every year the freeze continues, more estates cross the taxable threshold without any real increase in wealth.
The Nil Rate Band £325,000
The first £325,000 of your estate property, cash, investments, personal belongings, all of it is free from inheritance tax. Anything above that is taxed at 40%.
If you are widowed, your late spouse’s unused nil rate band transfers to you. That brings the combined threshold up to £650,000. For more on how this works in practice, see HMRC’s guidance on passing on a home.
Worked Example
A single aunt dies leaving £500,000 to her nephew. The first £325,000 is tax free. The remaining £175,000 is taxed at 40%. The nephew receives £430,000 and HMRC collects £70,000 from the estate before he sees a penny.
Residence Nil Rate Band. Why It Does Not Apply
On top of the £325,000 NRB, there is an extra £175,000 allowance called the Residence Nil Rate Band. It applies when you leave your main home to a direct descendant. A single person can shelter up to £500,000 this way; a married couple up to £1,000,000.
Nieces and nephews cannot access it. Full stop. It does not matter how the will is written. If the beneficiary is a niece or nephew rather than a child or grandchild, the £175,000 disappears.
Taper Warning: The RNRB tapers away for larger estates. Above £2,000,000, it reduces by £1 for every £2 of estate value and is fully gone at £2,350,000 (single) or £2,700,000 (couple).
If the estate is large, do not assume the full RNRB is available even for beneficiaries who would otherwise qualify.
Leaving a Family Business to Nieces 2026 IHT Rules
Before April 2026, a qualifying family business or farm could pass to anyone including a niece or nephew completely free of inheritance tax, with no cap on the value. That is no longer the case.
From 6 April 2026, Business Property Relief (BPR) and Agricultural Property Relief (APR) have a ceiling. The relief structure now works like this:
The New Relief Structure
- 100% relief applies to the first £2.5 million of combined qualifying APR and BPR assets per individual.
- Above £2.5 million, only 50% relief applies the effective IHT rate on that excess is 20% (40% standard rate, halved by the 50% relief).
- Married couples and civil partners can transfer unused allowance between them, protecting up to £5 million combined including where the first death occurred before 6 April 2026.
- AIM-listed shares no longer attract 100% relief. They now get 50% in all cases. Our BPR guide explains the qualifying rules in detail.
Note: The 20% effective rate above the cap is better than the 40% rate on ordinary assets. But on a £5 million business passed to a niece by a single owner, the tax bill above the cap can still exceed £250,000. That needs planning.
For the government’s full policy statement, see the HMRC announcement on the £2.5m threshold increase.
Does the Beneficiary Being a Niece Affect the Relief?
No. BPR and APR relief is calculated based on the type of asset, not who receives it. Your niece inheriting a qualifying trading business gets the same relief as a child would. The restriction that applies to nieces losing the RNRB is completely separate from BPR/APR.
To qualify for BPR, the business must be a trading business, not mainly investment-based. Qualifying assets include shares in unquoted trading companies, partnership interests, and business assets used in the trade. The deceased must have owned the asset for at least 2 years before death.
For APR, the land or property must be used for agricultural purposes. Both owner-occupied and tenanted farmland can qualify: 2 years if the owner occupies it, 7 years if it is let.
Worked Example Business Left to a Niece
An uncle dies in 2026/27 leaving a qualifying trading business worth £4,000,000 to his niece. No surviving spouse.
| Business value | Detail | Amount |
|---|---|---|
| Family business passed to niece | £4,000,000 | |
| APR/BPR 100% cap | First £2.5m fully exempt | −£2,500,000 |
| Remaining value | Above the £2.5m cap | £1,500,000 |
| 50% relief on rest | Half of £1.5m is exempt | −£750,000 |
| Taxable business value | After all BPR relief | £750,000 |
| NRB applied | Standard nil-rate band | −£325,000 |
| Net taxable estate | £425,000 | |
| IHT at 40% | Tax bill on net taxable estate | £170,000 |
| Effective rate | £170k on a £4m business | ~4.25% |
Without the NRB, the bill would have been £300,000. A trust structure or lifetime gifting plan could reduce it further but either approach requires advice before the event, not after. Talk to our inheritance tax planning specialists to model your specific situation.
Trust Structures and the Transitional Rules
Where a business exceeds £2.5 million in value, placing assets into a discretionary trust during your lifetime moves them out of your estate subject to the 7-year rule. Each trust set up before 30 October 2024 carries its own £2.5 million BPR/APR allowance. Trusts created after that date share a single £2.5 million cap if the same person created multiple trusts.
Transitional Rule: If you gifted qualifying BPR or APR assets on or after 30 October 2024 and die on or after 6 April 2026 within the 7-year window, that gift eats into your £2.5 million allowance retroactively.
Get advice before making business gifts. The sequencing matters and the transitional rules are strict.
Paying IHT in Instalments 10 Year Option
When a taxable estate includes a business or agricultural property, the executor does not have to pay the full IHT bill within six months of death. There is a legal right to spread payments over 10 annual instalments instead.
From 6 April 2026, this option was extended to cover all assets eligible for BPR or APR, not just property. For a family inheriting a business they want to keep running, this can mean the difference between a forced sale and an orderly succession. The HMRC consultation confirmed this extension applies to all APR/BPR qualifying assets.
How It Works
- Who can use it Any executor of an estate with qualifying business assets, agricultural property, or certain unlisted shares.
- Payment schedule IHT split into 10 equal annual payments. First payment is due six months after the end of the month in which death occurred.
- Interest HMRC charges interest on the outstanding balance throughout, linked to the Bank of England base rate. The interest is not tax deductible.
- Early repayment Allowed at any time with no penalty. If the asset is sold, the remaining balance becomes due immediately.
Note: On a £170,000 IHT bill, the 10-year option works out to roughly £17,000 a year plus interest.
Worth modelling the total interest cost before committing. If there is liquidity in the estate, paying early usually works out cheaper overall.
Lifetime Gifting What You Can Give Now
Several gifting allowances let you move money to nieces and nephews during your lifetime without it counting as part of your estate. HMRC’s rules on gifts and inheritance tax set out the full conditions.
Annual Exemption £3,000
Up to £3,000 per tax year can be given away entirely free of IHT, to anyone, in any combination. Unused allowance carries forward by one year only. So the maximum you can give using this route in a single year is £6,000.
Small Gifts £250 per person
You can give £250 per person to as many people as you like each tax year. You cannot combine this with the annual exemption for the same person in the same year.
Wedding Gift £1,000
Aunts and uncles can give a tax-free wedding gift of up to £1,000 to a niece or nephew on their marriage or civil partnership. Parents can give up to £5,000 and grandparents up to £2,500.
The 7 Year Rule Larger Gifts
Larger gifts are classed as Potentially Exempt Transfers (PETs). They are free of IHT if you survive for 7 years from the gift date. If you die within 7 years, the gift is added back into your estate. The tax rate reduces year by year under taper relief.
- 3–4 years before death: 32%
- 4–5 years: 24%
- 5–6 years: 16%
- 6–7 years: 8%
- 7+ years: 0%
Using Trusts to Pass Assets Outside the Estate
A discretionary trust moves assets out of your estate while you keep some say over how and when they are distributed to beneficiaries, including nieces and nephews. For a detailed breakdown, see our inheritance and trust tax overview.
- Assets in trust are generally outside your estate after 7 years, subject to the PET rules.
- Discretionary trusts face a 10-year periodic charge of up to 6% on trust value above the NRB, and an exit charge when assets are distributed.
- A bare trust hands full entitlement to the beneficiary at age 18 simpler, but the trustee has no control over timing.
- Trusts set up before 30 October 2024 each hold their own £2.5 million BPR/APR allowance.
Trust structures have compliance costs and HMRC reporting obligations. Get legal and tax advice before setting one up.
Write a Will Everything Else Depends on It
None of the planning in this guide does anything without a valid will. Without one, intestacy rules take over and under those rules, nieces and nephews inherit nothing unless every spouse, child, parent, and sibling has predeceased.
A will directs your estate to the people you choose. It also lets you structure gifts in a way that makes best use of BPR/APR, NRB, and trust arrangements. Review it after major life events and certainly after April 2026 if you own a business. See the government’s guidance on making a will for the basic requirements.
Action point: If your will was drafted before April 2026 and includes a family business, get it reviewed.
The new BPR/APR cap changes how business assets should be structured in a will, particularly for married couples who want to use both the £2.5m allowances.
Common Mistakes
- Assuming the RNRB applies It never does for nieces and nephews, regardless of what the will says.
- Missing the 7-year clock on gifts Large gifts made close to death pull straight back into the taxable estate.
- Not checking BPR eligibility Investment heavy companies and some holding structures do not qualify. Do not assume they do. See our BPR guide for the qualifying conditions.
- Missing the instalment election deadline it must be made on the IHT400 within the filing window. There is no retrospective route.
- Outdated wills post April 2026 the new BPR/APR cap changes the optimal drafting approach, particularly for married business owners wanting to use both allowances.
- Ignoring the RNRB taper estates above £2 million need to check this, especially where the deceased was widowed.
Commonly Asked Questions
Do nieces and nephews pay inheritance tax in the UK?
Not directly. Inheritance tax is paid by the executor of the estate, not the beneficiary. But the tax comes out of the estate before the niece or nephew receives anything. So it reduces what they actually inherit. The estate pays 40% on everything above £325,000 (the nil rate band), and nieces and nephews cannot access the extra £175,000 RNRB that applies when a home is left to a child or grandchild.
How much can I leave to a niece or nephew tax free in 2026/27?
A single person can leave up to £325,000 with no IHT at all. If you are widowed and your late spouse’s nil rate band is available, that rises to £650,000. You cannot use the RNRB to push it higher. If the estate includes a qualifying business or farm, the first £2.5 million of those assets also attracts 100% relief. So the total tax-free amount can be significantly higher for business owners.
Can a niece or nephew ever benefit from the Residence Nil Rate Band?
No. HMRC definition of direct descendants for RNRB purposes is fixed by statute. It covers children, grandchildren, stepchildren, adopted children, and foster children. Nieces and nephews are not included, and there is no workaround. The only way to access the RNRB when a niece or nephew is involved is to leave the property to a qualifying beneficiary (such as a child) and use other assets to benefit the niece or nephew.
What is the 7-year rule and does it apply to nieces and nephews?
Yes, it applies. Any cash gift you make during your lifetime to a niece or nephew is a Potentially Exempt Transfer (PET). If you survive for 7 years after making it, the gift is completely free of IHT. If you die within 7 years, the gift is added back into your estate. The rate of tax on it reduces the longer you survived after the gift from 40% (within 3 years) down through taper relief to 0% (after 7 years).
How does the new BPR/APR cap affect leaving a business to a niece in 2026?
From 6 April 2026, only the first £2.5 million of qualifying business or agricultural assets attracts 100% IHT relief. Value above that gets 50% relief, creating an effective 20% IHT rate on the excess. Previously there was no cap at all. A niece inheriting a £4 million trading business would now face a tax calculation on the £1.5 million above the cap. With BPR at 50%, that leaves £750,000 taxable before the standard NRB reduces it further. See the worked example above.
Can I pay the IHT in installments when a business is left to a niece?
Yes. From 6 April 2026, the executor of an estate containing BPR or APR qualifying assets can elect to pay the inheritance tax in 10 equal annual installments. Interest accrues on the outstanding balance. The election must be made on the IHT400 within the original filing deadline. It cannot be claimed retrospectively. If the business is sold before all instalments are paid, the full remaining balance becomes due immediately.
Do I need a will to leave money to my niece or nephew?
Yes. Without a valid will, the UK intestacy rules apply and under those rules, nieces and nephews inherit nothing unless your spouse, children, parents, and siblings have all died first. A will is the only way to guarantee your estate reaches your chosen beneficiaries. It also allows you to structure gifts in a way that makes best use of tax reliefs and allowances.
What happens under intestacy if I have no children?
If you die without a will, your estate passes under a strict legal hierarchy. Your spouse or civil partner receives the first £322,000 and half of everything above that. The remaining half goes to your children. If you have no children, your spouse or civil partner gets everything. Only if you have no spouse and no children does the estate pass to parents, then siblings, then nieces and nephews. Intestacy provides no control over who receives what or when.
Speak to IBISS & CO
The April 2026 changes to BPR and APR are still new, and many existing wills and estate plans were not drafted with them in mind. If you own a business, rent out farmland, or hold AIM shares and you want a niece or nephew to benefit the tax position looks different to how it did two years ago.
