Gift Aid is a UK government scheme that allows registered charities to reclaim the basic-rate income tax (20%) on donations made by UK taxpayers. Because you have already paid 20% tax on the money before donating, HMRC returns this to the charity — boosting a £1 donation to £1.25 at no extra cost to you. You authorise this by signing a Gift Aid declaration.

How much extra does Gift Aid add to a donation?

Gift Aid adds 25p for every £1 donated — a 25% boost to the charity from HMRC. This is because the 20% basic-rate tax paid on the donation equals 25p per 80p net donation (20/80 = 25%). So a £100 donation becomes £125 for the charity with no additional cost to you. Higher-rate and additional-rate taxpayers can also claim the difference between the basic rate and their higher rate through Self Assessment.

Can higher-rate taxpayers claim additional Gift Aid relief?

Yes. If you pay income tax at 40% or 45%, you can claim the difference between your tax rate and the basic rate (20%) through your Self Assessment return. For a higher-rate (40%) taxpayer, Gift Aid on a £100 donation gives the charity £125, and the donor can claim an additional £25 in tax relief via Self Assessment — making the net cost of the donation just £75. For additional-rate (45%) taxpayers, the donor's claim is £31.25 per £100 donated.

Who is eligible to use Gift Aid?

You are eligible to Gift Aid a donation if you are a UK taxpayer who has paid (or will pay) at least as much in income tax or Capital Gains Tax in the current tax year as the charity will reclaim on your donations. The amount reclaimed by the charity is 25p per £1. If you donate £100, HMRC pays the charity £25 — so you must have paid at least £25 in UK tax in the same year.

Gift Aid 2026/27 — How It Works for Donors, Higher-Rate Taxpayers & Charities

Gift Aid is the UK government’s scheme for boosting charitable donations at no extra cost to the donor. When you tick the Gift Aid box, the charity can reclaim the basic-rate income tax (20%) you paid on the donated money from HMRC — turning a £1 donation into £1.25 for the charity. For 2026/27, higher-rate taxpayers can also claim the additional 20% relief on top through Self Assessment, effectively reducing the net cost of their donation significantly.

Quick answer: Ticking Gift Aid when you donate costs you nothing extra — the charity receives 25p more per £1. If you pay 40% or 45% income tax, you can also claim back an additional 20% or 25% of the donation through your Self Assessment return. Always check the eligibility box before signing.

How Gift Aid Works: The Numbers

Scenario	Donor Pays	Charity Receives	HMRC Contributes
Without Gift Aid	£100	£100	£0
With Gift Aid (basic rate taxpayer)	£100	£125	£25
With Gift Aid (higher rate, 40% — after SA claim)	£75 net	£125	£25 (charity) + £25 (donor)
With Gift Aid (additional rate, 45% — after SA claim)	£68.75 net	£125	£25 (charity) + £31.25 (donor)

“Net” cost for higher-rate taxpayers reflects the additional relief claimed via Self Assessment.

Gift Aid Eligibility: Who Can Use It

You can Gift Aid your donations if:

You are a UK taxpayer — this means you pay income tax, Capital Gains Tax, or both in the current UK tax year
You have paid (or will pay) enough tax to cover what the charity reclaims — specifically, your total UK tax for the year must be at least 25% of the total donations you Gift Aid. If you over-donate relative to your tax liability, you may owe HMRC the shortfall
The donation goes to a registered UK charity — not to a community group, crowdfunding, or private individual

Important edge cases:

Scotland: Scottish taxpayers pay the Scottish Rate of Income Tax (SRIT), but Gift Aid still reclaims at the UK basic rate (20%). Scottish higher-rate taxpayers (41%) claim the 21% difference between their rate and 20% via their return
Non-UK income: If your income is mainly from sources not subject to UK tax (foreign pensions, overseas earnings), you may not be eligible
Pensioners: State Pension alone does not count as taxable income for Gift Aid purposes — you need to have paid actual tax in the year

How to Gift Aid a Donation

Step 1: Sign a Gift Aid declaration

When you make a donation, tick the Gift Aid box (online, on a form, or verbally) and confirm you are a UK taxpayer. This serves as your Gift Aid declaration. You can make a standing declaration with a charity that covers all past and future donations.

Step 2: The charity claims from HMRC

The charity (or a fundraising platform) submits a claim to HMRC and receives the additional 25p per £1 donated. This usually happens within 3–5 weeks of your declaration.

Step 3: Higher-rate taxpayers claim via Self Assessment

If you pay 40% or 45% income tax, claim the additional relief on your Self Assessment return. Enter the total amount of Gift-Aided donations on your return — the software or HMRC will calculate the additional relief automatically.

You can also request a self-assessment adjustment if you do not normally file SA: Contact HMRC and they can adjust your PAYE tax code to give you the relief through payroll.

Gift Aid and Self Assessment

When you file Self Assessment, you enter your total Gift Aid donations for the year. This does two things:

Extends your basic-rate band: Gift Aid donations extend the basic-rate band by the gross donation amount — meaning more of your income is taxed at 20% rather than 40%, effectively giving you the higher-rate relief
Reduces your income tax bill: The additional relief flows through to your tax calculation

Worked example — higher-rate taxpayer:

James earns £80,000 and donates £1,000 per year to charity with Gift Aid.

Charity receives: £1,000 + £250 (HMRC reclaim) = £1,250
James’s Self Assessment claim: £1,000 × 20% = £200 additional relief (the difference between 40% and 20% on the gross £1,250 donation)
Net cost of James’s £1,000 donation: £1,000 − £200 = £800

Carrying Back Gift Aid to the Previous Tax Year

You can elect to carry back Gift Aid donations made in 2026/27 to the 2025/26 tax year. This is useful if:

You had a higher income in 2025/26 and would get more relief
You made a large donation near the start of 2026/27 but want relief sooner

The election must be made before you file your 2025/26 Self Assessment return (by January 31, 2027).

Payroll Giving: An Alternative to Gift Aid

Payroll giving (also called Give As You Earn or GAYE) allows employees to donate directly from pre-tax salary through their employer’s scheme. This provides immediate tax relief at your marginal rate without requiring Gift Aid declarations or Self Assessment claims — the donation comes out before PAYE is applied.

Payroll giving gives the same effective relief as Gift Aid + Self Assessment claim, but is simpler and immediate. Ask your employer if they operate a payroll giving scheme.

Gift Aid and Other Reliefs

Gift Aid can be combined with:

Marriage Allowance — transfer unused personal allowance to spouse
ISA contributions — ISA and Gift Aid are independent reliefs
Pension contributions — pension contributions and Gift Aid both reduce taxable income

You cannot use Gift Aid for gifts to foreign charities (unless HMRC-recognised), political parties, or personal fundraising campaigns.

Gift Aid is one of the UK’s most efficient charitable giving tools — the charity receives 25% more than you donate, and higher-rate taxpayers also reclaim additional personal relief. If you regularly donate to charities and haven’t been Gift-Aiding or claiming via Self Assessment, this is a simple change that benefits both you and the organisations you support.
