GASDS Rules: The Gift Aid Small Donations Scheme Explained

The Gift Aid Small Donations Scheme (GASDS) lets your charity claim a 25% top-up on small cash and contactless donations without needing a Gift Aid declaration from each donor. It was designed for collection buckets, church plate, and contactless payment terminals where asking every donor to sign a form is simply not practical.

What GASDS lets your charity claim

GASDS pays a top-up equivalent to the Gift Aid rate of 25p for every £1 of qualifying donation. Your charity can claim on up to £8,000 of donations per tax year, which produces a maximum top-up of £2,000. No declaration is required from the donor. The scheme is available to charities and community amateur sports clubs (CASCs) that are recognised by HMRC for Gift Aid purposes.

The official HMRC guidance for the scheme is at gov.uk/claim-gift-aid/small-donations-scheme and gov.uk/guidance/claiming-a-top-up-payment-on-small-charitable-donations.

Which donations qualify

A donation qualifies for GASDS when it meets all three conditions:

• The amount is £30 or less. Each individual donation must be £30 or less. A £31 donation does not qualify at all; there is no partial claim on the first £30.
• It is paid in cash or by contactless payment. This includes coins, notes, contactless card transactions, and contactless device payments (such as a phone tap). Direct debits, cheques, and online bank transfers do not qualify.
• No Gift Aid declaration is attached. If a donor gives you a declaration, claim Gift Aid in the normal way instead. GASDS is the route when no declaration exists.

You do not need to identify individual donors. Aggregate your qualifying cash and contactless totals for the tax year and claim on that figure.

For the rules on Gift Aid itself, including declarations and the 25p-per-£1 mechanics, see the Gift Aid complete guide.

The annual limit and what the top-up is worth

Your charity can claim GASDS on up to £8,000 of qualifying donations per tax year. At the 25% top-up rate, that produces a maximum top-up of £2,000 per year. These figures are set by HMRC and apply per charity (or per community building where the community buildings rules apply).

Use the GASDS calculator to work out your claim quickly.

A worked example:

Qualifying donations collected	Top-up at 25%
£2,000	£500
£5,000	£1,250
£8,000 (maximum)	£2,000 (maximum top-up)
£10,000 (over the cap)	£2,000 (still capped at the £8,000 base)

The matching rule: why you need some Gift Aid claims too

GASDS is not a free-standing scheme. There is a matching rule: the donations on which you claim GASDS in a tax year cannot exceed 10 times the donations on which you claim Gift Aid in the same year.

This means you need at least some Gift Aid-eligible donations with proper declarations to support your GASDS claim. If your Gift Aid claim falls, so does your GASDS ceiling.

Worked example (taken directly from HMRC guidance):

Gift Aid donations (with declarations)	Maximum GASDS base (10x)	Maximum GASDS top-up (25%)
£100	£1,000	£250
£500	£5,000	£1,250
£800 or more	£8,000 (scheme cap)	£2,000 (maximum)

The direction matters: it is GASDS limited by Gift Aid, not the other way around. A charity that collects £8,000 in bucket donations but only has £50 of Gift Aid-eligible donations that year is limited to a GASDS claim on £500 (10 times £50).

Note: for donations collected on or after 6 April 2017, your charity does not need a prior Gift Aid track record to use GASDS. You just need to be making Gift Aid claims in the same year.

Community buildings and connected charities

Where qualifying events take place in a community building, additional £8,000 GASDS allowances can become available to connected charities or for particular buildings. The conditions include requirements around the number of events (at least 6 per year) and the number of people attending (at least 10 per event).

The community buildings rules add significant complexity and the sub-rules interact in ways that are easy to misread. The right approach is always to work through the HMRC guidance page directly: gov.uk/guidance/claiming-a-top-up-payment-on-small-charitable-donations. Do not try to estimate or apportion the allowances without reading that guidance carefully for your exact situation.

If the connected-charity or community-buildings position is not straightforward for your organisation, this is a good point to take professional advice. See the Gift Aid service page for how we help charities with GASDS and Gift Aid claims.

How to claim and the 2-year deadline

GASDS claims are submitted through HMRC's Charities Online service (the same portal used for Gift Aid). You can include GASDS alongside a Gift Aid claim or submit it separately.

The critical constraint is the 2-year deadline: claims must be made within 2 years of the end of the tax year in which the donations were collected. Miss the window and the top-up is lost.

For example, donations collected in the 2023/24 tax year (ending 5 April 2024) must be claimed by 5 April 2026. Charities that run annual Gift Aid claims often bundle GASDS in the same submission, which is good practice and avoids the risk of letting a year drop off.

Steps to prepare a claim:

1. Total your qualifying cash and contactless donations for the tax year (each £30 or less).
2. Confirm your Gift Aid donations for the same year. Your GASDS base cannot exceed 10 times that figure.
3. Apply the lower of: your actual qualifying total, the 10x matching ceiling, and the £8,000 scheme cap.
4. Submit via Charities Online. The 25% top-up is paid directly to the charity.

GASDS vs Gift Aid: when each applies

	Gift Aid	GASDS
Declaration needed?	Yes, from each donor	No
Per-donation limit	None	£30 or less
Annual cap on base	None	£8,000 of donations
Maximum annual top-up	No cap	£2,000
Top-up rate	25p per £1 donated	25p per £1 donated
Eligible payment types	Any (bank transfer, card, cash, cheque with declaration)	Cash and contactless only
Depends on other scheme?	No	Yes: matching rule ties GASDS to Gift Aid claims
Claim deadline	Check current HMRC guidance	2 years from end of tax year

The two schemes complement each other. Where a donor has given a declaration, claim Gift Aid in the usual way (there is no upper limit on Gift Aid claims). Reserve GASDS for the donations where a declaration was not practical. Together, they maximise what your charity recovers from HMRC on donations from UK taxpayers.

Common failure modes

These are the mistakes that most often result in lost GASDS claims or HMRC repayment demands:

• Letting the 2-year window close. The deadline is firm. A charity that has never claimed GASDS but has been collecting bucket donations for several years can only recover the two most recent tax years. Earlier years are gone.
• No Gift Aid claims in the same year. If you do not make any Gift Aid claims in a tax year, the matching rule leaves your GASDS ceiling at zero. You cannot claim GASDS that year.
• Including donations over £30. A single contactless donation of £32 does not qualify. Amounts above £30 must be excluded from the GASDS total, not rounded down.
• Including non-qualifying payment types. Online donations, bank transfers, cheques and direct debits do not qualify even if the donor did not provide a declaration. Only cash and contactless count.
• Swapping the matching rule figures. The rule is GASDS base limited by 10 times the Gift Aid donation total, not the other way around. Check which direction your records support before you prepare the claim.
• Claiming GASDS without HMRC recognition. Your charity must be HMRC-recognised for Gift Aid before it can use GASDS. Charity Commission registration alone is not sufficient (see gov.uk/charities-and-tax).

If your charity has missed GASDS years or is unsure whether its records support a claim, the Gift Aid service covers claim preparation and back-year recovery.
