Understanding the rules, reliefs, and planning strategies that shape what you pass on
Inheritance tax planning is ultimately about control. Control over what you leave behind, who receives it, when they receive it, and how much is lost to tax and administration along the way. For many families, it is also about avoiding uncertainty at a difficult time.

Where rules are changing, we have flagged the scheduled changes and their effective dates.
How inheritance tax works in the UK
Inheritance tax (IHT) is typically charged at 40% on the value of an estate above the available tax-free thresholds. The value of your estate includes property, savings, investments, personal possessions, and certain lifetime transfers, less allowable debts and reliefs.
In practice, many estates pay less than the headline rate because of exemptions, reliefs, and planning. However, the rules are detailed, and the cost of a mistake can be high, especially where gifts, trusts, or business assets are involved.
The latest nil-rate band thresholds
Nil-rate band
The nil-rate band (NRB) is the amount you can leave before IHT applies. It is £325,000.
If you are married or in a civil partnership, unused NRB can usually be transferred to the surviving spouse or civil partner, potentially doubling the threshold to £650,000 on the second death.
Residence nil-rate band
The residence nil-rate band (RNRB) is an additional threshold worth up to £175,000 when a qualifying residence is left to direct descendants (for example, children or grandchildren).
It can also be transferable between spouses or civil partners, which means a couple may have up to £350,000 of RNRB available in addition to the NRB, subject to the rules below.
The £2 million taper
The RNRB is reduced where the net value of the estate exceeds £2 million. The taper reduces the RNRB by £1 for every £2 above £2 million.
This is one of the biggest planning flashpoints for higher-value estates because the effective marginal IHT cost can jump sharply once the taper starts to bite.
Downsizing protection
If you downsized or sold a home (in certain circumstances) and still leave assets to direct descendants, the estate may be able to claim a downsizing addition, so you are not penalised for moving. There are strict conditions and time limits for claims.
The foundations of a good IHT plan
Understand what you own and how it is held
Effective inheritance tax planning starts with clarity. This means understanding not just what assets you own, but how they are owned. Jointly held property, pensions, life policies, business interests, and trusts can all be treated very differently for inheritance tax purposes. Without a clear picture of ownership and beneficiary arrangements, it is easy for well-intended plans to unravel.
Use thresholds and exemptions deliberately
Inheritance tax thresholds and exemptions are most effective when they are used intentionally. Nil-rate bands, residence nil-rate bands, and lifetime exemptions should form part of a coordinated plan rather than being relied on by default. Where allowances are left unused or triggered accidentally, estates often pay more tax than necessary.
Build a gifting strategy you can maintain
Gifting can be one of the most powerful tools in inheritance tax planning, but only if it is sustainable. Gifts that strain day-to-day finances or rely on assumptions about future income often lead to problems. A good gifting strategy is realistic, repeatable, and properly documented, so it can stand up to scrutiny if required.
Align wills and trusts with real intentions
Wills and trust structures should reflect how you actually want your wealth to be used and protected, not just how it looks on paper. This is particularly important where families are blended, beneficiaries are vulnerable, or assets are complex. When legal documents align with real-world intentions, planning becomes both more robust and more flexible.
When these foundations are in place, inheritance tax planning becomes less about reacting to rules and more about managing risk, preserving choice, and adapting to changing family circumstances.
Gifting rules and exemptions
Lifetime gifts are one of the most effective IHT tools because they can reduce the taxable value of your estate. But they are also the area where HMRC disputes are common.
Potentially exempt transfers and the 7-year rule
Most gifts to individuals are potentially exempt transfers (PETs). If you survive seven years from the date of the gift, the gift falls outside your estate for IHT.
If you die within seven years, the gift may become chargeable and can use up your NRB first. If IHT is payable on the gift, taper relief may reduce the tax liability if death occurs between three and seven years after the gift.
Annual and small gift exemptions
Key lifetime exemptions include:
- Annual exemption: up to £3,000 per tax year (and you can carry forward one unused year).
- Small gifts exemption: small gifts to individuals within the rules (commonly used for family gifting).
There are also specific exemptions for wedding or civil partnership gifts and for gifts to charities and certain political parties (rules vary by circumstance).
Normal expenditure out of income
One of the most powerful (and most misunderstood) exemptions is normal expenditure out of income. In broad terms, regular gifts from surplus income can be exempt if they do not reduce the donor’s standard of living and the pattern is evidenced.
The practical takeaway is simple: if you want to rely on this exemption, document it properly. A clear record of income, regular outgoings, and a consistent gifting pattern is often what separates a smooth probate process from a dispute.
Gifts with reservation of benefit
A common trap is giving something away while still benefiting from it. If you give away an asset but still enjoy it, it may be treated as a gift with reservation of benefit (GWR) and pulled back into your estate for IHT.
Recent tribunal commentary continues to show how harshly this can be treated when people “gift” property or assets but continue to use them in substance. In Chugtai v HMRC (2025), HMRC successfully argued that assets placed into trusts many years earlier were still effectively enjoyed by the deceased, bringing them into charge.
Trust structures and when they are used
Trusts are not only about tax. They are also about control, protection, and managing complexity (for example, second marriages, vulnerable beneficiaries, or family businesses).
The tax treatment depends heavily on the trust type and the nature of the assets involved.
Bare trusts
A bare trust is generally transparent for tax. The beneficiary is treated as owning the asset for many purposes. Bare trusts can be useful for straightforward gifting, but they do not provide the same control as other trust types.
Interest in possession trusts
An interest in possession (often called a life interest) trust can provide an income entitlement or right to benefit for one person (for example, a surviving spouse), while preserving capital for others (for example, children from a first marriage).
These are often used to balance family needs and protect long-term intent. The IHT position depends on the structure and timing and requires careful drafting.
Discretionary trusts
Discretionary trusts can offer strong control and flexibility, particularly where family circumstances may change or beneficiaries are young. However, they are usually subject to the relevant property regime, which can create periodic and exit charges depending on value and distributions.
They can also be used as part of a wider plan to manage how wealth is accessed over time, not simply to reduce tax.
Lifetime transfers into trust
Transfers into most trusts (other than certain exempt trusts) are typically chargeable lifetime transfers (CLTs). They can trigger an immediate IHT charge if the value exceeds the available NRB, and they interact with the seven-year framework differently from PETs.
Reliefs that can materially reduce IHT
Spouse and charity exemptions
Transfers to a spouse or civil partner are generally exempt from IHT, and gifts to qualifying charities are exempt. These are often the building blocks of “first death to spouse, second death to children” planning, with careful use of transferable NRB and RNRB.
Business and agricultural relief
Business Property Relief (often referred to as business relief) and Agricultural Property Relief can be highly valuable, but they are complex and under greater scrutiny.
The UK government has published changes scheduled to take effect from 6 April 2026, introducing a new structure for relief and changing how relief applies above certain allowances.
Case law also shows how fact-sensitive these reliefs are. In The Executors of Beresford v HMRC (2024), the tribunal found shares did not qualify as relevant business property in the circumstances considered. More recently, commentary around Boulting v HMRC (2025) has highlighted how relief outcomes can turn on detailed interpretation and facts.
The planning message is consistent: do not assume relief applies just because an asset “sounds” like a business or farm asset. Eligibility and structuring matter.
Pensions and IHT planning
Pensions have historically been a major estate-planning tool because many pension death benefits sit outside the estate in many plans. However, the UK government has announced a measure that would bring most unused pension funds and death benefits within the value of a person’s estate for IHT purposes from 6 April 2027 (subject to legislation and detail).
If you have built an estate plan around pensions as a primary IHT shelter, this is an area to review proactively.
Domicile changes and internationally mobile families
For internationally mobile individuals, the IHT regime has shifted. UK guidance notes that from 6 April 2025, deemed domicile rules were replaced by a new long-term UK resident framework for certain purposes.
If your estate includes overseas assets or you have non-UK family connections, this is a specialist area where small mistakes can lead to significant unexpected exposure.
A practical planning framework
If you want a structured way to approach IHT planning, this sequence is a reliable starting point:
1. Confirm the estate picture
List assets, ownership, beneficiaries, and approximate values. Include pensions, life cover, business interests, and any trusts.
2. Confirm the will, guardianship, and executors
A technically good tax plan fails if the will does not reflect the family reality, or if executors are not able to administer what you intended.
3. Use allowances deliberately
NRB, RNRB, annual exemptions, and income gifting exemptions tend to deliver the highest return on planning time when implemented consistently.
4. Build a gifting strategy you can maintain
A plan that relies on uncomfortable gifting rarely survives contact with real life. Sustainable gifting, properly documented, is usually better than aggressive gifting that creates reservation or affordability risks.
5. Consider trusts where control matters
Trusts are most valuable where they solve real family requirements (protection, second marriages, vulnerable beneficiaries, staged access), with tax treated as one part of the design.
6. Revisit the plan regularly
Estate planning is not set-and-forget. It should be reviewed after major life events and when rules change. Upcoming pension IHT changes from April 2027 are a good example of why.
