The Nil Rate Band: Your Inheritance Tax Threshold Explained
4 minute read
Understanding the nil rate band is key to knowing how much tax your estate may pay.
If you have ever looked into inheritance tax, you will almost certainly have come across the phrase “nil rate band”. It is one of the most important concepts in the whole subject, and understanding how it works is essential to understanding your estate’s inheritance tax position. Yet for something so fundamental, it is often misunderstood or only partially understood by people who are trying to plan their estates.
This guide explains what the nil rate band is, what it is currently worth, how it interacts with gifts made during your lifetime, how it can be doubled for married couples, and why its long freeze at the same level matters more and more as time goes on.

What Is the Nil Rate Band?
The nil rate band is the amount of your estate that can pass to your beneficiaries on your death without attracting inheritance tax. Think of it as a tax-free allowance that sits at the bottom of your estate. The value of your estate up to the nil rate band threshold is charged to inheritance tax at 0%. Everything above that threshold is generally charged at 40%.
The nil rate band is not just a threshold on death. It also applies to certain lifetime transfers, particularly gifts made into trusts that are classified as chargeable lifetime transfers. For those transfers, any amount above the available nil rate band over a rolling seven-year period is subject to inheritance tax at a lifetime rate of 20%. We cover how lifetime gifts interact with the nil rate band in more detail below.
The nil rate band is a personal allowance. Every individual in England and Wales has their own nil rate band, regardless of whether they are married, in a civil partnership, or single. It cannot be given to someone else or combined with another person’s allowance during your lifetime. However, as we explain in the section on married couples, an unused portion of the nil rate band can be transferred to a surviving spouse or civil partner after death.
What Is the Current Nil Rate Band Threshold?
The nil rate band is currently set at £325,000 per person. This means that the first £325,000 of a person’s estate passes free of inheritance tax on death. Any value above this figure is taxed at 40%, subject to any further exemptions, reliefs, or additional allowances that may apply.
The current threshold of £325,000 has been in place since April 2009. It has not moved in over fifteen years. The government has legislated that the nil rate band will remain frozen at £325,000 until at least April 2028, subject to future Budget decisions.
Why the Freeze Matters
A fixed threshold in a world of rising asset values has a significant practical consequence. Because the nil rate band does not increase with inflation or property prices, the proportion of estates that exceed it grows larger every year, even when those estates have not grown in real terms.
A person who owned a modest home worth £200,000 in 2009 and had modest savings may well have had an estate comfortably within the nil rate band at that time. The same property, now worth £350,000 or more in many parts of England and Wales, pushes the estate above the threshold even if nothing else has changed. Each year that the threshold remains fixed while property values and savings rise, more and more families find themselves in the inheritance tax net for the first time.
This is why inheritance tax is no longer a concern only for the very wealthy. It is increasingly relevant to middle-income homeowners with modest savings who have not previously had reason to think carefully about their estate planning.
Key figure: The nil rate band has been frozen at £325,000 since 2009 and is set to remain there until at least April 2028. As property values rise, more estates are drawn into the inheritance tax threshold each year.

The Spousal Exemption and the Transferable Nil Rate Band
For married couples and civil partners, the inheritance tax rules include two significant advantages that can substantially increase the amount that can pass to the next generation free of tax.
The Spousal Exemption
The first is the spousal exemption. Transfers between spouses and civil partners are generally fully exempt from inheritance tax, both during lifetime and on death. When the first partner in a couple dies, any assets that pass to the surviving partner are not subject to inheritance tax, regardless of their value. This exemption applies automatically and does not need to be claimed in any particular way, though it must be accounted for correctly in the estate administration.
It is worth noting that the spousal exemption only applies to transfers that actually pass to the spouse or civil partner. If part of the estate on the first death passes to children or other beneficiaries, that portion is not covered by the exemption and may be subject to inheritance tax in the usual way.
The Transferable Nil Rate Band
The second advantage for married couples is the transferable nil rate band. When the first partner dies and leaves everything (or a substantial portion of their estate) to the surviving partner, their own nil rate band may be entirely or partially unused. The unused portion is not lost. Instead, it can be transferred to the surviving partner and used in addition to their own nil rate band on the second death.
The transfer is calculated as a percentage of the nil rate band rather than as a fixed cash amount. This is an important detail. If the first partner to die had an unused nil rate band of 100% (meaning they left everything to their spouse and used none of their nil rate band), then 100% of whatever the nil rate band is worth at the time of the second death is transferred. So if the nil rate band has increased by the time of the second death, the surviving spouse benefits from the higher figure.
In practical terms, this means a married couple or civil partnership can have a combined nil rate band of up to £650,000 available on the second death, based on the current threshold of £325,000 per person. This can make a very significant difference to the amount of inheritance tax payable when the surviving partner eventually dies.
Key point: A married couple or civil partners may have up to £650,000 of nil rate band available on the second death, provided the first partner’s allowance was not used at the first death.
This Does Not Apply to Unmarried Couples
The transferable nil rate band and the spousal exemption are available only to married couples and civil partners. They do not extend to cohabiting couples or unmarried partners, regardless of how long they have been together or how established their relationship is. For couples who are not married, each partner’s estate is assessed on its own merits, with no ability to transfer the unused nil rate band between them. This is one of the most significant inheritance tax disadvantages of not being married, and it is a point that often comes as a surprise to people who have been in long-term relationships outside of marriage.
How Lifetime Gifts Can Reduce the Nil Rate Band
The nil rate band is not reserved solely for use on death. It can also be used up during a person’s lifetime, and this is one of the aspects of inheritance tax that most people find surprising and counterintuitive.
Many lifetime gifts do not use the nil rate band at all. The annual exemption of £3,000 per year, small gifts of up to £250 per person, wedding gifts, and gifts made from surplus income are all immediately exempt from inheritance tax and have no effect on the nil rate band. Similarly, outright gifts from one individual to another (known as potentially exempt transfers) do not use the nil rate band at the time the gift is made, though they may do so later if the donor dies within seven years.
The nil rate band is used by chargeable lifetime transfers: gifts that attract inheritance tax at the time they are made. The most common example is a transfer into a discretionary trust. When you make such a transfer, the available nil rate band over the previous seven years is applied first. Any amount of the transfer that falls within the remaining nil rate band is tax-free. Any excess above the nil rate band is taxed at 20% during your lifetime.
Lifetime Transfers Are Accounted for Before the Death Estate
The key rule to understand is that when calculating inheritance tax on your death estate, any chargeable lifetime transfers made in the seven years before death are taken into account first and applied against the nil rate band in chronological order. Only after those transfers have been set off against the nil rate band is the remaining allowance (if any) applied to the death estate itself.
If your lifetime transfers in the seven years before death have used up the entire £325,000 nil rate band, none of it remains to offset the value of your estate on death. The result is that a larger proportion of your estate is taxed at 40%. In the most extreme cases, where large chargeable transfers have exhausted the nil rate band entirely, your death estate may face a full 40% tax charge from the first pound.
This interaction between lifetime giving and the nil rate band on death is one of the more technically complex aspects of inheritance tax, and it is an area where it is easy to make expensive mistakes without proper advice.

The Seven-Year Rule and the Nil Rate Band
The seven-year rule is one of the most important concepts in lifetime gift planning, and it has a direct bearing on how the nil rate band is applied.
When you make a potentially exempt transfer (an outright gift to another individual), that gift is not charged to inheritance tax at the time it is made. If you survive for seven years, the gift becomes fully exempt and falls entirely outside your estate. It no longer uses any of your nil rate band and has no further effect on your inheritance tax position.
However, if you die within seven years of making the gift, the position changes. The gift is brought back into account and treated as part of your taxable estate for the purposes of calculating inheritance tax. It is applied against the nil rate band in chronological order alongside any other transfers made within the seven-year window. If the gift uses up some or all of the nil rate band, less of that allowance remains to offset the value of the death estate.
Taper Relief Does Not Restore the Nil Rate Band
A common misunderstanding is that taper relief reduces the amount of a failed gift that counts against the nil rate band. This is not correct. Taper relief reduces only the rate of inheritance tax that is payable on the excess above the nil rate band, where the gift was made between three and seven years before death. It does not reduce the value of the gift that is set against the nil rate band.
To illustrate this: if you made a gift of £400,000 five years before your death, and your nil rate band is £325,000, the gift uses up the full nil rate band. The remaining £75,000 is the taxable excess. Taper relief at the five-to-six year rate (a 60% reduction) would reduce the tax on that £75,000 from £30,000 to £12,000. But the nil rate band has still been fully consumed by the gift, and none of it remains available to offset your death estate. Your death estate is therefore taxed at 40% from the first pound.
This distinction matters enormously in practice. Taper relief is often assumed to reduce the impact of a failed gift on the nil rate band. It does not. It only reduces the tax rate on the excess.
Gifts Fall Outside the Estate After Seven Years
Once a gift has been made for more than 7 years, it falls entirely outside the estate and no longer uses any nil-rate band. This is the goal of lifetime gifting as a planning strategy: to make gifts early enough that they outlast the seven-year window, freeing up the nil rate band to be applied in full against the death estate.
For this reason, the timing of gifts is critical. A gift made at sixty-five has a strong chance of surviving the seven-year window. A gift made at eighty-two, after a serious diagnosis, is much less likely to do so, and the planning value may be limited or lost entirely.
What This Means for Your Estate Planning
The nil rate band is not a static or simple concept. Its interaction with lifetime gifts, with the death estate, with the spousal exemption, and with the seven-year rule creates a layered picture that requires careful thought. For people who are approaching the threshold, or who have already exceeded it, understanding how the nil rate band works in their specific circumstances is the starting point for any meaningful estate planning.
Your will plays a central role in this. How your estate is structured, who benefits from it, and in what order, can all affect how the nil rate band is applied and how much of your estate ultimately passes to the people you intend to benefit. A will that has not been reviewed recently, or that was drafted without attention to inheritance tax, may not be making the most of the allowances available to you.

Frequently Asked Questions
What is the nil rate band for inheritance tax?
The nil rate band is the amount of a person’s estate that is charged to inheritance tax at 0%. It acts as a tax-free threshold. For the 2024/25 tax year, the nil rate band is £325,000 per person. Anything above this figure is generally charged to inheritance tax at 40% on death.
What is the current nil rate band threshold?
The nil rate band is currently £325,000 per person. It has been frozen at this level since April 2009 and is legislated to remain at £325,000 until at least April 2028.
Can married couples combine their nil rate bands?
Yes. When the first partner in a married couple or civil partnership dies and leaves their estate to the surviving partner, their unused nil rate band can be transferred to the survivor. This means the surviving partner can have up to £650,000 of nil-rate band available on the surviving partner’s death, based on the current threshold. The transfer is calculated as a percentage of the nil rate band rather than a fixed cash sum.
What happens to the nil rate band if I make large gifts during my lifetime?
Certain lifetime gifts, particularly transfers into discretionary trusts, are set against the nil rate band over a rolling seven-year period. If those transfers use up the nil rate band before death, less (or none) of it remains available to offset the death estate. Lifetime transfers are always applied to the nil rate band before the death estate is calculated.
Does the seven-year rule affect the nil rate band?
Yes. If you make a gift and die within seven years, the gift is brought back into account and applied against the nil rate band in the order in which it was made. If the gift uses up the nil rate band, none of it remains available to offset the death estate. Gifts made more than 7 years before death fall outside the estate entirely and do not use any nil-rate band.
What is taper relief, and how does it affect the nil rate band?
Taper relief reduces the rate of inheritance tax payable on the excess of a failed gift above the nil rate band, where death occurs between three and seven years after the gift was made. It does not reduce the value of the gift that is applied against the nil rate band. The nil rate band is still fully used by the gift, even where taper relief applies to the excess.
Why has the nil rate band been frozen for so long?
The nil rate band was set at £325,000 in April 2009 and has not been increased since. This is a government policy decision, and the threshold has been legislated to remain frozen until at least April 2028. The practical effect of the freeze is that more estates are drawn into the inheritance tax net each year as property values and savings increase, even though the threshold itself has not moved.
Does the nil rate band apply to lifetime gifts?
Yes, in part. Small gifts, gifts to spouses, and gifts that qualify as exempt do not use the nil rate band. But chargeable lifetime transfers, such as transfers into most types of trust, are assessed against the nil rate band over a rolling seven-year period. Any transfer above the available nil rate band is subject to inheritance tax at the lifetime rate of 20%.
What is the difference between the nil rate band and the residence nil rate band?
The nil rate band (£325,000) applies to all estates. The residence nil rate band (currently £175,000) is an additional allowance available when a person leaves their home to their direct descendants, such as children or grandchildren. The two can be combined, meaning an individual may have up to £500,000 of combined threshold, or up to £1 million for a married couple. The residence nil rate band is subject to a tapered reduction for estates worth more than £2 million.
Do I need a will to use my nil rate band effectively?
A will does not increase the nil rate band, but a well-drafted will can ensure that the available allowances are used as effectively as possible. Without a will, the intestacy rules determine how your estate is distributed, and this may not make the best use of your nil rate band or your spouse’s transferable allowance. A will drafted with inheritance tax in mind gives you control over how the thresholds are applied and who ultimately bears the cost of any tax.
