Gift Aid and Legacies UK: What Charities and Donors Need to Know
Quick answer
Gift Aid does not apply to charitable legacies — charities cannot reclaim tax on gifts made through a will. However, charitable legacies are 100% exempt from inheritance tax under IHTA 1984, and leaving 10% or more of the net estate to charity reduces the IHT rate on the rest from 40% to 36%.
How Gift Aid Works — and Why It Cannot Apply to Legacies
Gift Aid is one of the most valuable tax reliefs available to UK charities. Under the scheme, a UK charity can reclaim basic-rate income tax from HMRC on cash donations made by UK taxpayers — adding 25p to every £1 donated at no additional cost to the donor. Higher and additional-rate taxpayers can also claim additional relief via self-assessment, reducing their effective cost of giving further.
The mechanism requires a Gift Aid declaration: a written confirmation from the donor that they are a UK taxpayer and that they authorise the charity to reclaim the basic-rate tax paid on the donation. This is a statement from a living, taxpaying individual — it is inherently a lifetime mechanism.
A legacy is a gift made in a will, which takes effect at death. At that point:
- The donor is deceased and cannot provide a declaration.
- The gift comes from the estate, not from the donor’s income as a taxpayer.
- The legal framework — HMRC’s Gift Aid rules — has no mechanism for a post-mortem claim in respect of a testamentary gift.
This is a common misconception among both donors planning their wills and charity fundraising teams. A bequest is not eligible for Gift Aid. However, as explained below, charitable legacies attract a different and equally powerful tax relief: the full IHT exemption.
Inheritance Tax Exemption for Charitable Legacies
Under section 23 of the Inheritance Tax Act 1984, any gift to a qualifying charity on death is completely exempt from inheritance tax. There is no monetary cap on the exemption — unlike the nil-rate band (£325,000) or residence nil-rate band (£175,000), the charitable exemption has no ceiling. A legacy of £5 million to charity attracts no IHT.
The practical effect is that a charitable legacy is fiscally neutral to your estate. Instead of the Treasury receiving 40% of the gift in IHT, the charity receives 100% of it. For the donor, the cost is the same — the question is only whether the money goes to the charity or to HMRC.
For a charity to qualify for the exemption under s.23 IHTA 1984, it must meet HMRC’s definition of a charity for tax purposes. In practice, this means:
- All UK-registered charities qualify automatically.
- Community Amateur Sports Clubs (CASCs) registered with HMRC also qualify for Gift Aid on lifetime donations but not for the s.23 IHT exemption on legacies — only charities proper qualify.
- Non-UK charities may qualify under post-2010 provisions, subject to HMRC case-by-case assessment.
The 10% Charitable Legacy Discount: Reducing IHT to 36%
Since 6 April 2012, estates that leave at least 10% of their “baseline amount” (broadly, the net taxable estate after the nil-rate band but before charitable deductions) to charity benefit from a reduced IHT rate of 36% rather than 40% on the remainder of the taxable estate. This is governed by Schedule 1A to the Inheritance Tax Act 1984 (inserted by Finance Act 2012).
The calculation involves identifying “components” of the estate — the general estate, the surviving spouse’s share (under joint tenancy survivorship), and nominated assets (life insurance, pension death benefits written in trust). The 10% test applies separately to each component. In practice, most estates where this relief is relevant involve only the general estate component.
- Estate value: £700,000
- Nil-rate band: £325,000 (assume no RNRB for simplicity)
- Baseline amount: £700,000 − £325,000 = £375,000
- 10% threshold: £37,500
- Without charitable legacy: IHT = 40% × £375,000 = £150,000
- With £37,500 charitable legacy: charitable legacy is IHT-exempt; remaining taxable estate = £375,000 − £37,500 = £337,500; IHT at 36% = £121,500.
The charity receives £37,500; IHT reduces by £28,500. Net cost of charity gift: £9,000.
The saving can be meaningful: in the example above, leaving £37,500 to charity costs the estate only £9,000 after the IHT saving — the Treasury effectively contributes £28,500 of the charitable gift.
Lifetime Charitable Giving: Where Gift Aid Does Apply
While Gift Aid cannot be used for legacies, it is extremely valuable during life. A basic-rate taxpayer donating £100 to charity under Gift Aid enables the charity to claim £25 from HMRC — the charity receives £125. A higher-rate taxpayer (40% rate) donating £100 can additionally claim back the difference between higher and basic rate tax (20% of the gross donation = £25) via self-assessment — reducing their net cost of giving to £75 for a £125 benefit to the charity.
Seven-year rule: Lifetime gifts to charity do not use up the nil-rate band and are not potentially exempt transfers (PETs). They are immediately exempt from IHT, regardless of when the donor dies — there is no seven-year survival requirement for charitable donations.
Payroll Giving allows employees to donate from gross salary before income tax, making it more tax-efficient than Gift Aid for higher-rate taxpayers who might not file self-assessment returns.
Structuring Charitable Gifts in Your Will
The two main approaches to charitable legacies are specific (fixed sum) and residuary (a share of what remains after other gifts). Each has different implications:
| Type | Example wording | Advantages | Disadvantages |
|---|---|---|---|
| Specific legacy | “£10,000 to Cancer Research UK” | Certainty for the charity; simple to understand | Does not grow with estate; may be eroded by inflation; must be updated |
| Residuary legacy | “25% of my residuary estate to the RNLI” | Grows with estate; automatically qualifies for 10% discount; no need to update | Amount uncertain until estate is administered; charity cannot plan on exact sum |
For the 10% IHT discount, a residuary legacy expressed as a percentage of the net estate will automatically adjust to meet the 10% threshold if the estate grows. A fixed cash legacy may fall short of the threshold if the estate value changes. If the 10% discount is important to your planning, a residuary percentage legacy of at least 10% is the more reliable approach.
Frequently Asked Questions
Can a charity claim Gift Aid on a legacy left in a will?▼
No. Gift Aid is a scheme under the Finance Act 1990 and subsequent legislation that allows UK charities to reclaim basic-rate income tax (currently 25p for every £1 donated) on cash donations made by UK taxpayers. Gift Aid applies only to lifetime gifts — it cannot be claimed on legacies (charitable bequests in a will). This is because Gift Aid requires a Gift Aid declaration from a living donor confirming they are a UK taxpayer and authorising the charity to reclaim the tax. A deceased person cannot make such a declaration, and the charity has no mechanism to reclaim tax from the estate under Gift Aid.
Is a charitable legacy exempt from inheritance tax?▼
Yes — completely. Under section 23 of the Inheritance Tax Act 1984, any gift to a qualifying charity (one registered with HMRC for IHT purposes — in practice, this includes all UK registered charities and many non-UK charities that qualify under the Finance Act 2010 cross-border charity provisions) is fully exempt from inheritance tax. There is no cap. A £1 million legacy to charity attracts no IHT whatsoever. The effect is that leaving money to charity in a will does not cost your estate — the charity receives the full value, and the amount is deducted from the estate before the IHT calculation.
Does leaving 10% of my estate to charity reduce inheritance tax for the rest?▼
Yes. Under the Finance Act 2012, if a person leaves at least 10% of their net estate (broadly, the estate value after the nil-rate band and other reliefs but before charitable deductions) to qualifying charities, the IHT rate on the rest of the taxable estate is reduced from 40% to 36%. This is sometimes called the 'charitable legacy IHT discount'. For an estate of, say, £600,000 with a £325,000 nil-rate band (taxable estate: £275,000), the threshold is 10% of £275,000 = £27,500. If at least £27,500 is left to charity, the remaining £247,500 is taxed at 36% (saving £9,900 versus the 40% rate). The saving can be substantial — and the combined effect of the IHT discount and the charity's own IHT exemption means the Treasury and the charity both benefit.
What is payroll giving and how does it differ from Gift Aid?▼
Payroll Giving (sometimes called Give As You Earn) is a scheme run through HMRC-approved Payroll Giving Agencies that allows employees to donate to charity directly from their gross salary before income tax is deducted. Because the donation is taken from pre-tax pay, the tax relief is applied at source — a higher-rate taxpayer donating £100 through payroll giving effectively costs them only £60 (since £40 income tax is not paid). This is more generous than Gift Aid for higher and additional-rate taxpayers, who would otherwise need to claim the additional relief via self-assessment. Payroll Giving is available only during life and from employment income — it has no interaction with legacies or estate planning.
What is the difference between a specific charitable legacy and a residuary charitable legacy?▼
A specific legacy is a fixed cash amount or named item given to a charity ('I give £10,000 to Cancer Research UK'). A residuary legacy gives the charity a share of the residue — what remains after all debts, costs, and specific gifts have been paid ('I give 25% of my residuary estate to the RNLI'). Both are fully IHT-exempt. The practical difference for estate planning is that a residuary legacy automatically increases in value with the estate — if your estate grows, the charity's share grows too. It also requires no updating when your circumstances change. A specific cash legacy, by contrast, may be eroded by inflation and does not automatically reflect growth in the estate. Many estate planners recommend residuary legacies to charity for long-term charitable giving strategies.
Can I leave a legacy to an overseas charity?▼
Under English law, a legacy to a non-UK charity can still qualify for the IHT exemption under section 23 of the Inheritance Tax Act 1984, provided the overseas charity meets HMRC's qualifying conditions. Since Finance Act 2010, charities established in the EU, Norway, Iceland, and Liechtenstein could qualify — but following Brexit, the rules have been subject to change. As of 2026, HMRC applies a case-by-case analysis to non-UK charities, focusing on whether the charity would meet the UK statutory definition. In practice, major international charities recognised in multiple jurisdictions generally qualify, but it is essential to verify the specific charity's IHT-qualifying status with a solicitor or HMRC before relying on the exemption in a will.
