Charitable Giving and Inheritance Tax

Charitable giving is one of the few areas of estate planning where doing good and cutting tax pull in exactly the same direction. Every pound you leave to a registered charity is a pound that never touches inheritance tax, and if you are generous enough, your gift can lower the rate of tax paid on everything else you leave behind.

This guide explains how the charity exemption works, how the reduced 36% rate is triggered, the difference between giving in your lifetime and giving in your will, and the practical steps to get the wording right so your wishes actually take effect. It is information, not personal advice: the figures are 2026/27 UK rules, and a good plan depends on your own circumstances.

How charitable gifts escape inheritance tax

Inheritance tax in the UK is charged at 40% on the value of your estate above your tax-free thresholds. For 2026/27 the nil-rate band is £325,000 per person, with a further residence nil-rate band of up to £175,000 where a home passes to direct descendants, both frozen until 2030. A married couple or civil partners can combine unused allowances to shelter up to £1m between them. You can read the full mechanics in our complete guide to inheritance tax planning, and check the current figures in what is the inheritance tax threshold.

Alongside the exemption for gifts between spouses and civil partners, there is a second unlimited exemption: gifts to qualifying charities. Anything you leave to a UK-registered charity (and certain EU and other qualifying charities) is deducted from your estate before inheritance tax is worked out. There is no cap. Leave £50,000 to a cancer charity and your taxable estate falls by £50,000; leave your entire estate to charity and there is no inheritance tax to pay at all.

Gifts to community amateur sports clubs, national museums, universities and certain heritage bodies can qualify on the same basis. The charity must be recognised by HMRC: a quick way to confirm is that it will have an HMRC charity reference or be on the Charity Commission register.

The reduced 36% rate: leave 10%, cut the rate

The rules go further than a simple exemption. If you leave at least 10% of your “net estate” to charity, the rate of inheritance tax on the rest of that part of your estate drops from 40% to 36%. This is sometimes called the reduced rate or the 10% rule, and it was designed to encourage larger legacies.

The “net estate”, HMRC calls it the baseline amount, is not the whole value of what you own. It is the value of the relevant part of your estate after subtracting the available nil-rate band, any reliefs (such as business or agricultural relief) and any other exemptions, but before deducting the charitable gift itself. You compare your charitable legacy against that baseline; if it clears 10%, the lower rate applies.

The elegant consequence is that once you are giving anywhere near 10%, giving the full tenth can cost your other heirs almost nothing, because the tax saving on the rest of the estate largely offsets the extra gift. It is one of the rare situations where being more generous barely dents what your family receives.

A worked example

Suppose a single person dies with a taxable estate of £700,000 after using their £325,000 nil-rate band, so the baseline amount for the 10% test is £375,000. The table shows what happens as the charitable legacy rises.

Look at the last two rows. Increasing the gift from £15,000 to £37,500, an extra £22,500 to charity, leaves the family with exactly the same £541,000, because crossing the 10% threshold cuts the tax bill by more than the extra donation. The charity is £22,500 better off at no further cost to the heirs. Below 10%, by contrast, every pound given simply reduces what the family receives, so the 10% line is the point worth aiming for if a charitable legacy appeals to you.

These numbers are illustrative and ignore the residence nil-rate band, which would change the baseline. This is why the reduced rate rewards careful arithmetic; our guide to reducing inheritance tax legally sets the charity rules alongside the other main levers.

The three components of your estate

The 10% test is not always applied to your whole estate as one lump. For the reduced rate, an estate is divided into up to three separate “components”: the survivorship component (jointly owned assets passing automatically), the settled property component (assets held in certain trusts) and the general component (everything else that passes under your will). The 10% test is applied to each component in turn.

That sounds fiddly, and it can be, but there is a useful feature. Executors can make an election to merge components so that a single charitable gift is measured against the combined baseline, which sometimes tips an estate over the 10% line that would otherwise fall short in one component. Because the interaction between components, trusts and the residence nil-rate band gets technical quickly, this is a classic point at which regulated advice earns its keep.

Ways to give

There are several ways to build charitable giving into your plan, and they are not mutually exclusive. Most people combine a will legacy with some lifetime giving.

• 1

  A legacy in your will

  The most common route. A pecuniary legacy is a fixed sum; a specific legacy is a particular asset; a residuary legacy is a share of whatever is left after other gifts. Residuary gifts flex with your estate and are often used to hit the 10% figure.

• 2

  Lifetime gifts of cash

  Donations made while you are alive leave your estate immediately and can attract Gift Aid, boosting the charity’s receipt and your own income tax position.

• 3

  Gifts of shares or land

  Giving qualifying shares, securities or land to charity can secure income tax relief and exempt the gift from capital gains tax, as well as removing the value from your estate.

• 4

  A charitable trust or foundation

  For larger or ongoing giving, a donor-advised fund or family foundation lets you commit capital now and direct grants over time. This is more involved and usually warrants professional and legal advice.

• 5

  Payroll Giving

  Regular donations straight from gross pay give immediate tax relief at your marginal rate, though these do not affect your estate directly.

Lifetime giving and Gift Aid

Gifts you make during your lifetime and gifts you leave in your will are both exempt from inheritance tax, but they carry different extra benefits. A lifetime cash donation under Gift Aid lets the charity reclaim basic-rate tax, adding 25p to every pound you give. If you pay income tax at the higher or additional rate, you can claim the difference between your rate and the basic rate through your tax return, so a £1,000 gift can cost a higher-rate taxpayer as little as £750 while the charity receives £1,250.

A legacy in your will, by contrast, cannot use Gift Aid, but it is the route that unlocks the reduced 36% inheritance tax rate. It also keeps the money available to you during your lifetime, an important comfort, since giving capital away permanently is not the right move if it leaves you short later on.

From April 2027 unused pension funds are due to be drawn into the inheritance tax net, which makes charitable and estate planning matter for many more families than before. If a larger slice of your wealth will now be taxable on death, the case for building a charitable strategy, and reviewing the whole plan, is stronger. Investments can fall as well as rise, and this is information rather than personal advice.

Getting the wording right

Good intentions fail on bad drafting. A charity can change its name or merge, so a well-drafted will names the charity, its registered charity number and a clause allowing the gift to pass to a successor body. If you are aiming for the reduced rate, the wording matters even more: a fixed cash legacy may drift below 10% if your estate grows, whereas a clause expressed as “such sum as equals 10% of my baseline amount for the purposes of the reduced rate” keeps you on the right side of the threshold automatically. The Institute of Legacy Management and STEP publish model clauses that solicitors use for exactly this.

Because the sums are large and the rules interlock with trusts, the residence nil-rate band and the coming pension changes, most people benefit from professional help.
