Gift Aid in 60 seconds: when to tick the box (and when not to)
Gift Aid is valuable, but it is not a bonus to add to every payment. The key questions are whose money it is and whether you have paid enough UK tax.
Gift Aid lets an eligible charity claim an extra 25p for every £1 you donate, at no extra cost to you. A £20 donation could therefore become £25 for the charity.
The box is valuable, but it is not a general bonus to add to every payment. HMRC's detailed guidance was updated in June 2026. Here is the short version for donors.
Tick the box when all three statements are true
1. It is your own money
The donation must come from you. It can be paid by bank transfer, including an instant bank payment, but you cannot normally apply Gift Aid to money you have collected from friends, family or colleagues and then pass on as one payment.
2. You are making a genuine donation
You are not buying a ticket, entering a raffle, paying for goods or receiving a significant benefit in return. Those payments may still raise important funds, but they are not necessarily Gift Aid donations.
3. You have paid enough UK tax
In the same tax year, you must have paid at least as much UK Income Tax or Capital Gains Tax as all the charities you support will reclaim on your Gift Aid donations.
For a £20 Gift Aid donation, the charity can normally claim £5. If you make several Gift Aid donations during the tax year, consider the total tax reclaimed across all of them.
Leave it unticked in these common situations
- You collected £100 from colleagues and are paying it to the charity in one transaction.
- A parent or friend gave you money to donate on their behalf.
- The payment is for a raffle ticket, event admission, an auction purchase or another good or service.
- You are donating on behalf of a limited company. Company donations follow different tax rules.
- You have not paid enough UK Income Tax or Capital Gains Tax to cover the Gift Aid that charities would reclaim.
Leaving the box unticked does not reduce your original donation. It simply means the charity will not claim Gift Aid on that payment.
What about a message from the whole family?
The message does not decide who owns the money.
If you donate £20 of your own money and write "with love from the whole family", the donation can still qualify if the normal conditions are met. If another family member gave you the £20 to pass on, it is not your own donation and you should not apply Gift Aid in your name.
What happens on Wonderful.org?
When you make an eligible donation through Wonderful.org, you can complete a Gift Aid declaration during the donation journey. Wonderful passes the declaration data to the charity. The charity then makes its own claim directly from HMRC.
Your donation itself is made by instant bank payment and transferred directly to the charity's bank account. Wonderful.org does not deduct a platform or processing fee and does not ask you to add a tip.
If you are unsure
Do not guess. Leave Gift Aid unticked and check the current HMRC guidance, or ask the charity. This is especially important for sponsored events where money has been collected from other people, or where tickets, goods, benefits or challenge costs are involved.
Gift Aid works best when the declaration is accurate. One honest pause can save a charity extra administration later.
The next time you donate, ask two questions: is this my money, and have I paid enough UK tax? If both answers are yes and it is a genuine gift, the Gift Aid box may be right for you.
