Can anyone claim Gift Aid?

Only registered charities. If you are not yet registered, register first (free, 10 minutes online). Then register for Gift Aid separately with HMRC (also free).

Do donors need to do anything?

Just sign a simple Gift Aid declaration form. For online donations, a checkbox works. Once they sign, you can claim on all their gifts for 4 years backwards.

What if a donor pays tax but we do not know it?

You cannot claim Gift Aid. You must have a signed declaration saying they paid enough tax. Do not guess.

Gift Aid for Small Charities: The Easy Money Left on the Table

For every £80 a UK taxpayer donates, you can claim an extra £20 from the government. Most small charities do not claim it. Here is how.

A donor gives your small charity £80. Invisible to the donor, HMRC transfers an additional £20 to you. This is Gift Aid. Hundreds of small charities are not claiming it.

Why Gift Aid works

The government assumes that 20% of an individual's charitable donation came from tax they paid. So they reimburse the charity 20%, bringing the gift to £100 net for the charity (even though the donor only gave £80).

For a small charity with £5,000 in individual donations per year, Gift Aid adds £1,250. For free.

The small-donations scheme (even easier for tiny charities)

If you are a small charity (under £25k turnover), you can claim up to £300 per month (£3,600/year) via the small-donations scheme. You do NOT need Gift Aid declarations.

You simply declare "We received £500 in small donations this month, so we are claiming £300." HMRC approves it as long as you stay under the limit.

This is perfect for charities that receive cash donations or are still building a donor base.

Registering for Gift Aid: 5 steps

Step 1: Register as a charity (if not already)

Online with the Charity Commission (free, 10 minutes). You get a charity number.

Step 2: Register for Gift Aid with HMRC

Online at HMRC.gov.uk, search "Gift Aid." It asks for your charity number and who signs Gift Aid claims.

Step 3: Create a Gift Aid declaration form

Use the template from HMRC or Charity Commission. It asks: Are you a UK taxpayer? Do you want the charity to claim Gift Aid on your donations? Get them to sign (or tick a box online).

Step 4: Collect signatures

For in-person donors: hand them a form, they sign, you keep it. For online donations: add a Gift Aid checkbox at checkout; if they tick it, you have a record.

Step 5: Submit claims to HMRC

You can claim quarterly or annually. Go to the HMRC online portal, enter your donations (with donor names if over £250), and submit. HMRC pays you within 2-4 weeks.

Practical process: managing Gift Aid as a small charity

Monthly routine

Export donor list from fundraising platform (or manual list).
Check each donor has a Gift Aid declaration on file.
Separate declared donors from non-declared.
Total: X amount from declared donors.
Store safely (you need to keep declarations for 6 years).

Quarterly or annual claim

Log into HMRC online portal.
Enter total donated by Gift Aid donors.
Enter their names and postcodes (for audit trail).
Submit.
Receive payment in 2-4 weeks.

Pro tips to maximize Gift Aid

1. Ask at every opportunity

At events, in email, on your website: "Are you a UK taxpayer? Tick here to boost your gift by 25%."

2. Keep declarations safe

HMRC can audit. If a donor sues or there is a question about their tax status, you need proof they declared. Keep digitally (password-protected) or on file.

3. Do not claim on non-qualifying donations

Gift Aid works on voluntary donations from individual taxpayers. Grants from trusts, government, or people who do not pay enough tax do not qualify. Only claim on donations that qualify.

4. Backdate up to 4 years

If you did not claim Gift Aid in prior years but have declarations on file, you can go back 4 years and claim retroactively. This is a one-time windfall if you never claimed before.

Mistakes to avoid

Claiming on non-taxpayers. Do not assume everyone pays enough tax. If they do not have a declaration, do not claim.
Losing declarations. Keep them organized. A lost declaration means a lost claim later.
Claiming on grants. Grants from trusts and foundations do not qualify. Only individual donations.
Late claims. HMRC has deadlines. Submit quarterly or annually on schedule, not randomly.

Gift Aid is free money from the government. The fact that most charities are not claiming it is baffling. Do it today.

The back-of-envelope calculation

If your small charity has £10,000 annual donations from individuals, and 50% are UK taxpayers who declare Gift Aid:

Declared donations: £5,000.
Gift Aid claimable: £5,000 × 20% = £1,000.
Total income: £11,000 (vs £10,000 without Gift Aid).

That is a 10% boost to fundraising. For free. Do it this week.
