Is inheritance tax different in Northern Ireland?
No. Inheritance tax is one of the few parts of estate law that is genuinely UK-wide. The Inheritance Tax Act 1984 applies in Northern Ireland exactly as it does in England, Wales and Scotland, HM Revenue & Customs collects it from Belfast estates as it does from Birmingham ones, and every threshold on this page is the same on both sides of the Irish Sea.
What is different in Northern Ireland is everything around the tax: the court that grants probate, the forms the tax is reported on, and the kind of assets Northern Ireland estates tend to hold. This guide covers the UK rules first and the Northern Ireland specifics after.
The thresholds in 2026
| Allowance | Amount | Notes |
|---|---|---|
| Nil-rate band | £325,000 | Every estate. No tax on the first £325,000. |
| Residence nil-rate band | up to £175,000 more | Only where a home passes to children (including adopted, foster or step-children) or grandchildren. Takes the threshold to £500,000. |
| Married couples and civil partners | up to £1 million combined | Whatever the first to die does not use passes to the survivor, so a couple leaving a home to children can shelter £1m. |
| Estates over £2 million | residence band tapers away | The extra £175,000 is only available in full where the estate is under £2 million. |
| Rate above the threshold | 40% | Charged only on the part above the allowances. |
| Reduced rate | 36% | Where at least 10% of the net estate is left to charity. |
The £325,000 figure has not moved since 2009 and is currently frozen until April 2031, which is why more ordinary estates drift into the tax each year without anyone changing the rules.
Who actually pays it
Fewer people than fear it. Anything left to a spouse or civil partner is exempt however large, and so is anything left to charity. An estate only pays tax when what it leaves to everyone else, added together, exceeds the allowances. For a married couple who own a home and leave it to their children, that is £1 million between them before a penny is due.
The people caught are typically the widowed owner of a house who has no spouse left to leave it to, the person who never married and so has no exemption to use, and the farming or business family whose land is worth far more than it earns. Northern Ireland has more than its share of the third group, which is why the next section matters more here than it does in most of England.
Farms and family businesses: the rules that changed in April 2026
Agricultural property relief and business property relief used to take qualifying farmland and trading businesses out of inheritance tax entirely. From 6 April 2026 that changed. HMRC’s reform gives each estate a £1 million allowance on the combined value of property qualifying for 100% agricultural or business relief; above that, relief drops to 50%, so the excess is effectively taxed at 20% rather than 40%. Shares traded on markets designated “not listed” (such as AIM) now get 50% relief in all cases, and the option to pay in ten interest-free annual instalments is extended to all agricultural and business property.
For a Northern Ireland farm that has been in the family for generations, this is the single biggest inheritance-tax question there is, and it is not one a Will alone can answer. What a Will can do is make sure the farm passes to the people who will keep farming it, so that the relief is claimed on land that stays in use, and that the instalment option is available to the executors rather than forced into a sale. Anyone with a farm or business over £1 million should take specialist tax advice on lifetime planning; ClearLegacy does not give tax advice and a Will is not a tax plan.
Gifts and the seven-year rule
You can give away what you like while you are alive. Gifts to individuals fall out of your estate completely if you survive them by seven years; die sooner and they are counted back in, with taper relief reducing the tax on gifts made between three and seven years before death. Small gifts, the £3,000 annual exemption, wedding gifts and regular gifts out of surplus income are exempt outright. If you give away your home and carry on living in it without paying a market rent, HMRC treats it as though you still own it.
Pensions from April 2027
Most pension funds currently sit outside the estate and pass by nomination rather than under the Will. From 6 April 2027 unused pension funds are brought within inheritance tax. They will still pass by nomination, but their value will count towards the threshold, which will pull some Northern Ireland estates over the line that are under it today.
How inheritance tax is reported when you apply for probate in Northern Ireland
This is where the process differs from England and Wales. Inheritance tax must be dealt with with HMRC before the Probate Office in Belfast or Londonderry will issue a grant.
- Excepted estates (broadly, estates under the threshold or passing to a spouse or charity): for deaths on or after 1 January 2022 there is no separate HMRC form. Instead you give details of the assets, and the extra information HMRC needs, on the Northern Ireland Estate Summary Form NIPF7 that goes in with your probate application.
- Everything else: you complete HMRC’s full account, form IHT400, and pay any tax due, and only then apply for the grant using NIPF1 (where there is a Will) or NIPF2 (where there is not).
Tax is normally payable by the end of the sixth month after the death, and interest runs after that whether or not the grant has been issued. Our probate guide covers the Northern Ireland forms, fees and offices in detail.
What a Will can and cannot do about inheritance tax
A Will cannot change the thresholds. It can make sure you use them. Three things a Northern Ireland Will does that intestacy does not:
- It keeps the spouse exemption whole. Under Northern Ireland’s intestacy rules a surviving spouse with no children does not take everything if a parent or sibling survives — they take £450,000 and half the rest, and the relatives take the other half. That half is not spouse-exempt, so an estate that would have paid nothing under a Will can pay tax under intestacy. Our intestacy guide sets out the shares.
- It can secure the residence nil-rate band by leaving the home to children or grandchildren, which intestacy may not do.
- It can leave 10% to charity and bring the rate on the rest down from 40% to 36%.
A Will is the first step, not the last
ClearLegacy makes Wills for Northern Ireland, drafted under the 1994 Order, for £69 (£99 for Mirror Wills). We do not give tax advice and we do not offer estate planning — for a farm or business over £1 million, see a specialist as well.

Frequently asked questions
Is inheritance tax different in Northern Ireland?
No. The Inheritance Tax Act 1984 applies across the whole UK, so the £325,000 nil-rate band, the £175,000 residence allowance, the 40% rate and the spouse and charity exemptions are identical in Northern Ireland. What differs is the probate process: tax is reported to HMRC before the Probate Office in Belfast or Londonderry issues a grant, using form NIPF7 for excepted estates or IHT400 otherwise.
What is the inheritance tax threshold in Northern Ireland in 2026?
£325,000 for every estate, rising to £500,000 where a home passes to children or grandchildren and the estate is under £2 million. A married couple or civil partners can combine their allowances to £1 million. The £325,000 figure is frozen until April 2031.
Do farms in Northern Ireland pay inheritance tax?
From 6 April 2026 the first £1 million of combined agricultural and business property in an estate gets 100% relief and anything above that gets 50% relief, so the excess is effectively taxed at 20%. The tax on that property can be paid in ten interest-free annual instalments. Before April 2026 qualifying farmland was relieved in full.
Does a Will reduce inheritance tax in Northern Ireland?
A Will cannot change the thresholds, but it can make sure they are used. It keeps everything to a spouse exempt where Northern Ireland's intestacy rules would give parents or siblings a share; it can direct the home to children so the residence allowance applies; and leaving 10% of the net estate to charity cuts the rate on the rest from 40% to 36%.
Who pays the inheritance tax on an estate in Northern Ireland?
The estate does, through the executor or administrator, before the assets are distributed. Beneficiaries do not normally pay tax on what they inherit, though they may pay income tax or capital gains tax on what the inheritance earns afterwards.
When does inheritance tax have to be paid?
By the end of the sixth month after the death. Interest runs from then whether or not probate has been granted, which is why the HMRC account is dealt with before the Northern Ireland probate application rather than after.
Are pensions subject to inheritance tax in Northern Ireland?
Most pension funds currently pass by nomination outside the estate and are not taxed. From 6 April 2027 unused pension funds are brought within inheritance tax across the UK, including Northern Ireland.
Which form do I use to report inheritance tax when applying for probate in Northern Ireland?
For an excepted estate where the death was on or after 1 January 2022, no HMRC form is needed: the asset details and inheritance tax information go on the Northern Ireland Estate Summary Form NIPF7 with the probate application. Where tax is due or full details are needed, HMRC's form IHT400 is completed first.
