Donating to charity shouldn’t cost you more than it needs to. Gift Aid is a simple UK government scheme that lets charities reclaim tax on your donations — and if you’re a higher rate taxpayer, you can claim back extra tax too.
The result: a £100 donation costs you just £75, while the charity gets £125. Here’s how it works and how to make sure you’re using it properly.
What Is Gift Aid?
Gift Aid is a scheme that lets registered UK charities reclaim the basic rate tax you’ve already paid on your donation. When you donate £1, the charity can claim an extra 25p from HMRC — so your £1 becomes £1.25 at no extra cost to you.
The charity reclaims the 20% basic rate tax that was deducted from the money before you donated it. Since basic rate tax is 20% on 80% of income (the gross amount), that works out to 25% of the net donation.
How It Works in Practice
| Your Donation | Tax the Charity Claims | Total Received by Charity | Your Cost (Basic Rate) | Your Cost (Higher Rate) |
|---|---|---|---|---|
| £10 | £2.50 | £12.50 | £10 | £7.50 |
| £50 | £12.50 | £62.50 | £50 | £37.50 |
| £100 | £25 | £125 | £100 | £75 |
| £500 | £125 | £625 | £500 | £375 |
Gift Aid Tax Relief: Who Benefits?
Basic Rate Taxpayers
If you pay basic rate Income Tax (20%), Gift Aid doesn’t give you any extra tax relief personally. But the charity benefits — they get 25p more for every £1 you donate. You simply donate from your post-tax income, and the charity reclaims the tax.
Higher Rate Taxpayers
If you pay higher rate Income Tax (40%), you can claim back the difference between the basic rate (20%) and the higher rate (40%) on the gross donation. That’s an extra 25p for every £1 you donate.
Example: £500 donation
| Step | Calculation |
|---|---|
| You donate | £500 |
| Charity reclaims (25%) | £125 |
| Total received by charity | £625 |
| You claim back (20% of gross) | £125 |
| Your actual cost | £375 |
You give £500, the charity gets £625, and you get £125 back through Self Assessment. Your net cost is £375.
Additional Rate Taxpayers
If you pay additional rate Income Tax (45%), you can claim back the difference between the basic rate and additional rate — that’s 25% of the gross donation, same as higher rate taxpayers. The extra relief beyond basic rate is capped at 25p per £1 donated.
Gift Aid Rules
To use Gift Aid, you must meet these conditions:
For the Donor
- You must be a UK taxpayer
- You must have paid enough UK Income Tax and/or Capital Gains Tax to cover the amount the charity will reclaim
- The donation must be your own money — not from a company, trust, or third party
- You must make a Gift Aid declaration (the charity will provide this)
For the Donation
- The donation must be to a registered UK charity
- It must be a genuine gift — not a payment for goods or services
- It can be a one-off or regular donation
- There’s no minimum or maximum amount
The Gift Aid Declaration
Every charity you donate to must have a Gift Aid declaration from you. This is usually a simple form or tick box that confirms:
- You are a UK taxpayer
- You understand that if you pay less Income Tax and/or Capital Gains Tax than the amount of Gift Aid claimed, it’s your responsibility to pay the difference
- You want the charity to treat your donation as Gift Aid
You only need to make the declaration once per charity — it covers all future donations unless you cancel it.
What Happens If You Don’t Pay Enough Tax?
If you claim Gift Aid but haven’t paid enough tax to cover it, HMRC will contact you and ask you to repay the difference. For example, if you donate £1,000 and the charity claims £250 in Gift Aid, you need to have paid at least £250 in UK tax that year.
How to Claim Gift Aid
If You’re a Basic Rate Taxpayer
You don’t need to do anything extra. The charity reclaims the tax automatically once you’ve made a Gift Aid declaration. There’s nothing to claim on your Self Assessment.
If You’re a Higher or Additional Rate Taxpayer
You can claim the extra relief in one of two ways:
Option 1: Self Assessment
When you complete your Self Assessment tax return, include your Gift Aid donations in the relevant section. HMRC will adjust your tax code or refund the difference.
Option 2: Contact HMRC Directly
If you don’t file a Self Assessment return, you can contact HMRC directly to claim the relief. Call the Income Tax helpline or write to HMRC with details of your donations.
Keeping Records
Keep a record of:
- How much you donated to each charity
- The date of each donation
- The Gift Aid declaration (the charity should keep a copy, but keep your own records too)
HMRC can ask for evidence if they query your claim.
Gift Aid on Investments
Gift Aid isn’t limited to cash donations. You can also benefit from charitable giving through certain investments.
Charitable Trusts
If you invest in a charitable trust, you can claim Gift Aid on your investment. The trust reclaims the basic rate tax, and you can claim higher rate relief on your Self Assessment.
Shares and AIM Stocks
Donating shares to charity is tax-efficient:
- You don’t pay Capital Gains Tax on shares donated to charity
- The charity can sell the shares without paying CGT
- You can claim Gift Aid on the market value of the shares
- Higher rate taxpayers can claim additional relief
To donate shares, transfer them to the charity’s account or use a share donation scheme.
Payroll Giving
Some employers offer payroll giving schemes, where donations are taken from your salary before tax. This means:
- You get immediate tax relief at your highest rate
- The charity receives the gross amount
- No need to claim through Self Assessment
Gift Aid and Inheritance Tax
Gifts to registered charities are exempt from Inheritance Tax (IHT). There’s no limit and no seven-year rule — they’re immediately outside your estate.
Additionally, if you leave at least 10% of your estate to charity in your will, the IHT rate on the rest of your estate drops from 40% to 36%.
Example:
| Scenario | Estate Value | Charity Gift | Taxable Estate | IHT at 40% | IHT at 36% | Total IHT |
|---|---|---|---|---|---|---|
| No charity gift | £500,000 | £0 | £175,000 | £70,000 | — | £70,000 |
| 10% to charity | £500,000 | £50,000 | £125,000 | — | £45,000 | £45,000 |
Leaving £50,000 to charity saves your estate £25,000 in IHT.
Worked Example: Higher Rate Taxpayer
Sarah earns £60,000 and pays higher rate tax. She donates £200 to her local hospice.
| Item | Amount |
|---|---|
| Donation | £200 |
| Charity reclaims (25% of gross) | £50 |
| Total received by hospice | £250 |
| Sarah claims back (20% of gross) | £50 |
| Sarah’s actual cost | £150 |
Sarah claims the £50 relief on her Self Assessment return. The hospice receives £250. Sarah’s net cost is £150.
Common Mistakes
1. Not Making a Declaration
If you don’t complete a Gift Aid declaration, the charity can’t reclaim the tax. Always tick the Gift Aid box or fill in the form.
2. Claiming Without Paying Enough Tax
If you’re a higher rate taxpayer but your total tax bill is less than the Gift Aid claimed across all your donations, you’ll have to repay the difference to HMRC.
3. Forgetting to Claim Higher Rate Relief
Many higher rate taxpayers forget to include Gift Aid donations on their Self Assessment. This leaves money on the table — potentially hundreds of pounds per year.
4. Donating Company Money
Gift Aid only applies to personal donations. If you donate from a company account, the company can claim corporation tax relief instead, but you can’t claim Gift Aid personally.
5. Not Keeping Records
HMRC may ask for evidence of your donations. Keep receipts, bank statements, and copies of Gift Aid declarations.
Charities That Benefit Most from Gift Aid
All registered UK charities benefit, but smaller charities especially rely on Gift Aid. Consider:
- Local hospices and hospitals
- Community groups and food banks
- Environmental and conservation charities
- Educational and research charities
- Medical research charities
Many charities now offer online donation forms with built-in Gift Aid declarations — making it quick and easy to ensure they claim the full amount.
