Gift Aid for Charity Events: A UK Fundraiser's Guide

What Gift Aid is and why it matters for events

Gift Aid is a UK tax relief scheme that lets charities reclaim 25p for every £1 donated by a UK taxpayer. That means a £100 donation becomes £125 at no extra cost to the donor. For a charity running fundraising events, Gift Aid can add thousands of pounds in additional income across a single evening — money that would otherwise stay with HMRC.

The scheme works because UK taxpayers have already paid income tax (or capital gains tax) on their donations. Gift Aid lets the charity claim back the basic rate of tax the donor already paid. Higher-rate taxpayers can also claim back the difference between their tax rate and the basic rate on their personal tax return — so both parties benefit.

For event fundraisers, the question is never whether Gift Aid matters. It clearly does. The question is which payments at your event actually qualify — and that distinction trips up more organizations than any other part of the process.

Which event payments qualify for Gift Aid

This is where most confusion starts. Not every pound that changes hands at a charity event is a donation, and Gift Aid applies only to genuine donations — payments where the donor receives nothing (or nothing significant) in return.

Payments that qualify

• Straightforward donations: Cash donations, text-to-give gifts, and online donations made at the event. The donor gives money and receives nothing tangible in return. These qualify for Gift Aid as long as a valid declaration is in place.
• Sponsored event participation: If someone runs a 5K or takes part in a challenge event and collects sponsorship, those sponsorship payments are donations to the charity and can carry Gift Aid — provided each sponsor completes a declaration.
• Voluntary top-ups: If a guest at your event voluntarily adds a donation on top of an auction purchase or ticket price, that voluntary portion can qualify — but only if it is clearly separated from the payment for goods or services.

Payments that do not qualify

• Event tickets: If the ticket price covers entry to a dinner, gala, or concert, the attendee is receiving something in return (the event experience). That payment is not a donation and does not qualify for Gift Aid.
• Auction purchases: When a bidder wins an item at auction, they are buying something. The payment is consideration for goods, not a donation. (There is a narrow exception for the portion above fair market value — more on that below.)
• Raffle tickets: The purchase of a raffle ticket is a payment for the chance to win a prize. It is not a donation. Gift Aid does not apply.
• Goods and services: Anything purchased at a charity shop, merchandise stall, or food and drink counter at the event.

The underlying principle is simple: if the donor receives a benefit in return for their payment, it is not a donation for Gift Aid purposes. HMRC applies a "benefit threshold" — if the value of benefits received exceeds certain limits relative to the donation, the entire payment is disqualified.

The Gift Aid declaration

A Gift Aid declaration is the formal statement a donor makes confirming they are a UK taxpayer and authorizing the charity to claim Gift Aid on their donation. Without a valid declaration, the charity cannot make a claim — no matter how clearly the payment is a donation.

What the declaration must include

HMRC requires every Gift Aid declaration to contain:

• The donor's full name
• The donor's home address (including postcode) — HMRC uses this to verify the donor's tax status
• A statement that the donor wants the charity to treat the donation (and, optionally, all future and/or past donations) as Gift Aid donations
• A statement that the donor is a UK taxpayer and understands they must pay enough income tax and/or capital gains tax to cover the amount reclaimed by all charities they donate to
• The name of the charity

The declaration can cover a single donation or be an ongoing declaration covering all future (and past four years of) donations to the same charity. For events, an ongoing declaration is ideal — it means donors who give again later are automatically covered without filling out another form.

When to collect it

The declaration can be collected before, during, or after the donation is made. At events, the practical moment is at the point of donation — during the checkout or giving process. The key is making it frictionless enough that donors actually complete it, rather than skipping past it because the form is too long or the queue is too slow.

Record keeping

Charities must keep Gift Aid declarations and donation records for at least six years after the tax year the donation was made. HMRC can audit your claims, and if you cannot produce the declaration, you may have to repay the Gift Aid you claimed.

How to collect Gift Aid at events

The collection method makes a significant difference to your Gift Aid claim rate. Charities that rely on paper forms at busy events consistently report lower completion rates than those using digital collection.

Paper forms

The traditional approach: printed declaration forms at donation stations, on tables, or handed out by volunteers. Paper works, but it has real drawbacks at events. Forms get lost. Handwriting is illegible. Donors skip the address field because the queue is moving. Volunteers forget to hand them out during the busiest moments of the evening. The result is missed claims — often on the largest donations of the night.

Digital collection at checkout

The more reliable approach: collect the Gift Aid declaration as part of the digital donation or checkout flow. When a donor gives online, via a mobile bidding platform, or through a text-to-give system, the declaration is built into the payment process. The donor ticks a box, confirms their address, and the data is captured cleanly — no paper to chase, no handwriting to decipher.

Digital collection also makes ongoing declarations practical. A donor who completes a declaration through your platform is covered for future donations without repeating the process. That compounds the value over time.

Gift Aid and raffles

This is one of the most common points of confusion at charity events, so it is worth stating plainly: Gift Aid does not apply to raffle ticket purchases.

When someone buys a raffle ticket, they are paying for the chance to win a prize. That is a purchase, not a donation. It does not matter that the raffle is run by a charity or that the proceeds go to a good cause — the payment is consideration for entry into a prize draw, and HMRC does not treat it as a qualifying donation.

This applies to all forms of prize draws, lotteries, and raffles. If the buyer receives (or has the chance to receive) something in return, the payment is not a Gift Aid-eligible donation.

However, if you run a raffle alongside other fundraising activities at your event, the separate donations guests make during the same evening — to a paddle raise, a text-to-give campaign, or a straight cash donation — can still qualify for Gift Aid. The key is keeping raffle purchases and donations separate in your records.

Gift Aid and auction items

Auction purchases are more nuanced than raffles, but the default position is the same: the purchase price of an auction item is not a donation for Gift Aid purposes because the bidder receives goods in return.

There is a narrow exception. If a bidder pays more than the fair market value (FMV) of an item, the amount above FMV could potentially be treated as a donation — and that portion might qualify for Gift Aid. For example, if an item has a fair market value of £200 and the winning bid is £350, the £150 above FMV might be claimable.

In practice, this is difficult to apply at scale because:

• You need a defensible FMV for every item, established before the auction
• You need to clearly separate the "purchase" portion from the "donation" portion in your records and receipts
• The donor needs to complete a Gift Aid declaration specifically for the donation portion
• HMRC scrutinizes these claims carefully

For silent auctions and live auctions alike, the safest approach is to treat auction proceeds as non-Gift-Aid income and focus your Gift Aid efforts on the genuinely separate donations at the event — paddle raises, direct giving, and text-to-give appeals. If you want to pursue the above-FMV route, consult HMRC guidance and consider getting advice from a qualified tax advisor before submitting claims.

How momoGood handles Gift Aid at events

momoGood's events and auctions platform includes built-in Gift Aid collection that meets HMRC requirements. When a UK donor makes a donation through the checkout flow — whether at a gala, a silent auction, or an online fundraising campaign — the Gift Aid declaration and address capture are part of the process.

Here is what that looks like in practice:

• HMRC-compliant declaration: The Gift Aid declaration text meets HMRC's requirements and is presented at the point of donation. Donors confirm with a single action — no separate form, no paper to chase.
• Address capture: The donor's home address (required by HMRC to verify taxpayer status) is collected as part of checkout. No address means no valid claim, so the platform captures it at the moment the donor is already engaged.
• Automatic for every UK event: Gift Aid collection is available for every event on the platform. Your team does not need to configure it separately or build custom forms — it is part of the standard donor experience.
• Clean records: Every declaration is stored digitally alongside the donation record. When it is time to submit your Gift Aid claim to HMRC, the data is already organized — donor name, address, donation amount, date, and declaration status.

The goal is to remove the friction that causes charities to miss Gift Aid claims at busy events. When the declaration is embedded in the giving flow rather than sitting on a clipboard at the back of the room, completion rates go up — and so does the 25% top-up your charity receives.

Common Gift Aid mistakes at events

These are the errors that cost charities the most money, and they are all avoidable:

• Not collecting declarations at all. Some event teams assume they can sort out Gift Aid after the event. By then, donors have left, contact details are incomplete, and follow-up emails go unanswered. Collect declarations at the point of donation.
• Claiming Gift Aid on raffle tickets. Raffle ticket purchases are not donations. Claiming Gift Aid on them is incorrect and can trigger an HMRC audit and repayment demands.
• Claiming Gift Aid on auction purchases. The full purchase price of an auction item is not a donation. Only the portion above fair market value might qualify, and even that requires careful documentation.
• Missing the address. A Gift Aid declaration without the donor's home address is invalid. HMRC needs the address to verify taxpayer status. If your form or checkout flow does not capture it, your claim will fail.
• Not keeping records. Declarations and donation records must be kept for at least six years. Losing a box of paper forms or failing to export digital records before switching platforms can void years of claims.
• Assuming corporate donations qualify. Gift Aid applies to donations from individuals, not companies. Corporate sponsorships and business donations follow different tax rules.
• Forgetting the donor's responsibility. The declaration must make clear that the donor needs to have paid enough UK income tax or capital gains tax to cover the Gift Aid claimed by all charities they donate to. If a donor is not a taxpayer (or has not paid enough tax), the charity should not claim on their gift.

Making Gift Aid work at your next event

Gift Aid is straightforward when you know which payments qualify and you collect declarations at the right moment. The 25% uplift is significant — across a fundraising event raising £20,000 in eligible donations, that is an additional £5,000 from HMRC at no cost to your donors.

The practical steps are clear: separate donations from purchases in your event accounting, collect HMRC-compliant declarations as part of your digital giving flow, and keep your records clean. Focus your Gift Aid efforts on the payments that genuinely qualify — direct donations, paddle raises, and text-to-give gifts — and treat auction and raffle income as what it is: event revenue, not Gift Aid-eligible donations.
