What this covers
This handbook is a practical guide to Gift Aid for a small UK charity: what it is and what it is worth, who and what qualifies, the declaration you must hold, how to claim through HMRC, the Small Donations Scheme and retail Gift Aid, the tricky situations that catch charities out, and how to avoid the errors HMRC looks for. Everything is checked against HMRC guidance and reflects the rules as at July 2026.
Gift Aid is the closest thing a UK charity has to free money: with a little paperwork, the taxman adds a quarter to what your donors give, and it costs the donor nothing. Yet a great deal of it goes unclaimed every year, usually because a declaration was not asked for or the records were not kept. This handbook aims to change that — to help you claim everything you are entitled to, correctly, and to stay on the right side of HMRC while you do it.
What Gift Aid is and the current rate
Gift Aid is a UK tax relief that lets a charity or Community Amateur Sports Club reclaim the basic-rate Income Tax a donor has already paid on a donation. Because donations are treated as made after 20% basic-rate tax, a charity can claim an extra 25p for every £1 given — so a £100 Gift Aid donation becomes £125 to the charity, at no extra cost to the donor.
In the tax year to April 2026, HMRC repaid UK charities £1.88 billion in Gift Aid, up 10% on the year before. (Source: HMRC, UK charity tax relief statistics, updated 1 July 2026.) The maths is simple once you see it: the donation is “grossed up” by multiplying by 100/80, so £100 given is treated as £125 before tax, and the charity reclaims the £25 of basic-rate tax. The 25% top-up follows directly from the 20% basic rate of Income Tax, which remains the basic rate for the current 2026/27 tax year.
It is worth being clear about who can use Gift Aid and on what. The relief applies to gifts of money — cash, cheque, card, standing order or online — from individual UK taxpayers to charities and CASCs that HMRC recognises for tax. It does not apply to donations from companies, which claim their own tax relief by deducting gifts from profits, and it does not apply to gifts that are not money, such as goods or shares, though those can attract other reliefs. Gift Aid has been running in its modern form since 2000, so it is well established and consistently applied by HMRC — which means getting the basics right is more than enough to claim with confidence.
There is a bonus for the taxpayer, too. Donors who pay tax at the higher or additional rate can personally reclaim the difference between their rate and the basic rate on their Gift Aided donations, through their tax return — worth over £900 million to donors in the last year. That is their relief to claim, not the charity’s, but it is a useful thing to mention to supporters who pay higher-rate tax. Work out what a donation is worth with the Gift Aid calculator, and note that a CASC can claim Gift Aid in the same way.
Who and what qualifies
You can claim Gift Aid on gifts of money from individuals who pay enough UK Income Tax or Capital Gains Tax to cover the tax reclaimed on all their donations in the year, and who have given you a valid declaration. The gift must be a genuine, freely given donation — not a payment for something. You cannot claim on company donations, payments for goods or services, or gifts where the donor receives a significant benefit in return.
The donor’s tax position is central. Gift Aid reclaims tax the donor has already paid, so the donor must have paid at least as much Income or Capital Gains Tax in the year as every charity and CASC will reclaim on their donations. If they have not, they may have to make up the difference to HMRC, so the declaration includes a statement confirming they understand this. It is the donor’s responsibility, not the charity’s, but you should never encourage someone to Gift Aid a donation if you know they do not pay UK tax.
A helpful way to picture the qualifying conditions is a short mental checklist for each donation: is it a gift of money, from an individual, given freely with nothing significant in return, by someone who pays enough UK tax, and covered by a valid declaration? If every answer is yes, you can almost certainly claim. If any answer is no or ‘not sure’, pause and check before you add it to a claim. Building this check into how you take donations — on the form, at the event, in the database — stops errors before they happen, which is far easier than unpicking them after an HMRC review. Most disallowed claims trace back to a donation that failed one of these tests and was claimed anyway.
Just as important is knowing what does not qualify, because claiming on the wrong things is a common and costly error. Gift Aid cannot be claimed on: payments for goods or services; the price of a raffle or lottery ticket; the cost of attending an event or buying a ticket; a compulsory or minimum payment for entry; donations of goods (though the retail Gift Aid scheme provides a route for donated goods); or donations from companies, which get tax relief a different way. If in doubt about whether a payment is a genuine gift, treat it with caution and check HMRC’s guidance.
The Gift Aid declaration
A valid Gift Aid declaration is what makes a claim legal, and missing or incomplete declarations are the single most common reason charities have to repay Gift Aid after an HMRC check. A valid declaration must give the charity’s name, the donor’s full name and home address, identify the donations it covers, and include the donor’s statement that they have paid enough UK Income or Capital Gains Tax to cover the claim.
Declarations come in two forms. A single declaration covers one specific gift; a multiple, or ‘enduring’, declaration covers donations over a period — typically the past four years and all future gifts until the donor says otherwise. Enduring declarations are far more useful for regular donors, because you do not have to ask again each time. Declarations can be made in writing, online, or verbally — but a verbal declaration, for example over the phone, must be followed by a written record sent to the donor, who then has 30 days to cancel.
Small details on the declaration matter more than they might seem. The donor’s home address is required — not a work address or an email alone — because HMRC uses it to match the donor to their tax record, and a missing or partial address is one of the most common reasons a claim is disallowed. The declaration must also make clear which donations it covers and name your charity correctly. If a donor’s circumstances change — they stop paying enough tax, or change their name or address — they should tell you, and you should update or stop claiming accordingly. A tidy system for capturing and storing declarations, so each one is complete and easy to find, is the foundation of safe claiming.
The practical rules are straightforward. Use HMRC’s model wording as the basis for your form, and never alter the tax statement. Keep every declaration safely for as long as you might need it to support a claim, and make sure you can link each donation to a valid declaration. Asking for a declaration should become a habit at every opportunity — at events, with regular gifts, on your donation form and website. A ready-to-use Gift Aid declaration template, in single and multiple-donation versions, accompanies this handbook.

Claiming Gift Aid
To claim Gift Aid you must be recognised by HMRC as a charity for tax purposes, keep your declarations and donation records, and submit claims through HMRC’s Charities Online service or approved software. For most donations you can claim going back up to four years, so it is worth reviewing older gifts for valid Gift Aid you have not yet claimed before that window closes.
Getting set up is a one-off task. Your charity applies to HMRC to be recognised for tax, which includes confirming that your managers meet the fit and proper persons test, and then enrols for Charities Online. From there you submit a claim by attaching a schedule of your donations — a spreadsheet in HMRC’s format, or a file from your donation software — listing the donors and amounts. Small charities without software can use HMRC’s spreadsheet; larger ones often claim straight from their database.
Claiming need not be onerous once you are set up. Many charities claim in regular batches — monthly or quarterly — which keeps the schedules manageable and the income flowing, rather than leaving one large claim to the end of the year. If you use fundraising or membership software, it can usually produce the claim file directly, matching donations to declarations automatically; if not, HMRC’s spreadsheet does the job for a smaller charity. You can also claim Gift Aid on donations collected through many online giving platforms, though it is worth checking whether the platform claims on your behalf or leaves it to you, so the same donation is neither missed nor claimed twice.
Records are what make claiming safe. Keep your declarations, a record of each donation and how it links to a declaration, and an audit trail HMRC could follow. Keep them for the period HMRC requires — generally several years — because a claim can be checked after it is paid. Claims are usually paid within a few weeks. Doing this well sits alongside your wider compliance record-keeping, covered in the UK Charity Compliance Handbook.
The Gift Aid Small Donations Scheme (GASDS)
The Gift Aid Small Donations Scheme lets you claim a Gift Aid-style top-up on small cash and contactless donations without collecting a declaration — for the loose change in a collection tin, bucket or on a contactless plate, where getting each donor’s details is impractical. The top-up is worth 25% of the donations, up to a yearly limit.
The limits are specific. You can claim the top-up on up to £8,000 of small donations of £30 or less each in a tax year, giving a maximum top-up of £2,000. Qualifying donations must be cash or contactless — cheques, standing orders and bank transfers do not count — and you do not need to know who the donor is. There is also a matching rule: your GASDS claim cannot be more than ten times the amount of ordinary Gift Aid you claim in the same year, so you must be claiming some Gift Aid too.
GASDS is genuinely valuable for charities that take cash. Consider a small charity that collects £2,000 a year in loose change through tins and a contactless plate: under GASDS that is worth up to £500 in top-up, for very little work and no declarations — provided it is also claiming at least £200 of ordinary Gift Aid to satisfy the matching rule. (Illustrative example.) The scheme was designed precisely for the money you can never attach a name to, so it complements ordinary Gift Aid rather than replacing it. If your charity runs collections of any kind, GASDS should be part of your routine claiming, not an afterthought.
A few conditions apply. You must be an established charity already claiming Gift Aid, and you must keep records of the small donations you collect and bank. Separate ‘community buildings’ rules can increase what you can claim if you run activities in more than one building, such as a church with several halls. You claim GASDS through the same Charities Online service as Gift Aid. Because it needs no declaration, GASDS is one of the simplest ways for a small charity to add income from cash collections it could not otherwise Gift Aid.
Retail Gift Aid
Retail Gift Aid lets a charity claim Gift Aid on the money raised from selling a supporter’s donated goods — clothes, books, bric-a-brac in a charity shop. It works because the shop sells the goods as the donor’s agent: the goods remain the donor’s until sold, and the donor then donates the sale proceeds to the charity under Gift Aid. It turns donated-goods income into Gift Aid, but it needs a declaration and some extra administration.
Here is the mechanism. When a supporter brings in goods, they agree that the shop will sell the items on their behalf and make a Gift Aid declaration. After a sale, but before claiming, the charity tells the donor the net proceeds and must give them at least 21 days to respond, so the donor can take the money (less any agreed commission) or confirm they are donating it. Streamlined rules reduce the paperwork: a one-off declaration can cover proceeds of up to £100 a year (or up to £1,000 where shops are run through a trading subsidiary) before the charity has to write to the donor, and HMRC provides template letters for the Standard Method and Methods A and B.
The scheme exists because donated goods themselves cannot be Gift Aided — Gift Aid applies only to gifts of money. Retail Gift Aid gets around this by turning the goods into money first: the shop acts as the supporter’s agent, sells the items, and only then does the supporter donate the cash proceeds, which can be Gift Aided like any other cash gift. This is why the paperwork exists — the declaration, the agency agreement, and the letter telling the donor what their goods raised. It is more involved than a bucket collection, but for a charity with a shop it can lift the value of donated stock by a quarter, which across a year is significant.
Two points matter in practice. Gift Aid is claimed on the sale proceeds after any commission (including VAT on that commission) has been deducted, and the donor must still be a UK taxpayer who has given a valid declaration, exactly as for a cash gift. Retail Gift Aid carries more admin than an ordinary donation, so it suits charities running shops with a system to track goods, sales and donor letters — but for those charities it can add substantially to the value of every bag of donations.
Gift Aid in tricky situations
Some payments need care because the donor gets something in return, or because the payment is not really a gift at all. Gift Aid can only be claimed on genuine gifts of money, and where a donor receives a benefit in return for their donation, the value of that benefit must stay within HMRC’s donor-benefit limits — otherwise the whole payment fails to qualify.
The situations that most often catch charities out are membership subscriptions, events and sponsored challenges. A membership subscription can qualify for Gift Aid if the benefits members receive are within the limits and are not the real reason for paying. The price of an event ticket or a place at a fundraising dinner is not a donation — it is a payment for admission — although a genuine extra gift on top can be. With sponsored challenges, the sponsorship money supporters give is a donation and usually qualifies, but a participant’s own costs, or a payment that merely buys their place, do not. Auctions, raffles and lotteries have their own rules and generally do not qualify.
Split payments are often the practical answer. Where someone pays for a place at a dinner or a sponsored event, you can usually treat the part that covers the actual cost as a non-Gift-Aidable payment, and any genuine extra gift on top as a donation that qualifies — provided you are clear with the supporter about which is which. For events, describe the ticket price and any suggested donation separately. For membership, look hard at what members actually get for their money. The safest approach with anything that mixes payment and gift is to separate the two cleanly, document how you did it, and only claim on the genuine gift.
Behind these examples sit HMRC’s donor-benefit rules, which set out how much a donor can receive in return before Gift Aid is lost — broadly, benefits worth up to 25% of the donation for smaller gifts, tapering for larger ones, subject to an overall cap. The detail is genuinely fiddly, and the thresholds are set by HMRC, so treat this section as a flag to check rather than a formula to apply from memory. When a donation comes with anything in return, confirm the current donor-benefit limits on GOV.UK, or take advice, before you claim.
Common errors and HMRC audits
HMRC can check a charity’s Gift Aid claims and reclaim tax — sometimes with interest and penalties — where a claim turns out to be wrong, so accuracy matters more than volume. The most common errors are missing or invalid declarations, claiming on payments that are not genuine gifts, and claiming for donors who have not paid enough tax to cover the reclaim.
The avoidable mistakes are worth listing plainly: holding no declaration, or one missing the donor’s home address or the tax statement; claiming on event tickets, raffle entries, or payments for goods and services; claiming on donations from companies; failing the GASDS matching rule; and poor records that cannot link a donation to a valid declaration. Almost all of these come down to two habits — asking for a proper declaration every time, and keeping records that tie each claimed donation to one.
It is worth understanding why HMRC checks Gift Aid at all: the relief pays out real public money against declarations the charity holds, so HMRC samples claims to make sure the money is going where it should. A check is not an accusation, and most amount to no more than a request to see some declarations. Charities that keep good records, claim only on genuine gifts, and review their own processes occasionally have little to fear. The charities that come unstuck are usually those that claimed enthusiastically on everything without holding the declarations to back it up — which is why the dull work of record-keeping is the best insurance you can have.
If HMRC does check your claims, a calm, well-documented response is your best protection: produce your declarations and donation records, and show how each claim was supported. Keep those records for the period HMRC requires, make sure your managers continue to meet the fit and proper persons test, and correct any errors you spot yourself rather than waiting to be asked. Treating Gift Aid records with the same care as the rest of your compliance means an audit is an inconvenience, not a crisis.
How much Gift Aid goes unclaimed
A striking amount of Gift Aid is never claimed. Research commissioned by HMRC has estimated that around £560 million of Gift Aid goes unclaimed each year, and the Charities Aid Foundation has found that roughly a quarter of eligible donors do not add Gift Aid when they give. For a small charity, claiming what you are already owed is one of the simplest ways to increase income without asking anyone for more money.
The reasons are mundane. Donors are not asked for a declaration; charities do not keep the records needed to claim; cash collections that could use GASDS are banked without a thought; and higher-rate donors miss the personal relief they could pass back. None of these are hard to fix, but they add up to a lot of money left on the table across the sector year after year. (The £560 million figure is an older estimate and the true number moves with giving levels, so treat it as an indication of scale rather than a precise current total.)
There is a wider point about fairness to your own cause. Every pound of Gift Aid you fail to claim is a pound of public money, already set aside for charities, that your charity simply does not receive — while the donor gave exactly the same. Claiming it is not aggressive or pushy; it is making sure the support your donors intended reaches you in full. Many small charities find that a short push on Gift Aid — a declaration drive among existing supporters, a review of the last four years, and switching on GASDS — adds more to their income than a new fundraising campaign would, and at a fraction of the effort.
The practical steps are the same ones this handbook has set out: ask every eligible donor for a declaration, and use enduring declarations so you only ask once; claim GASDS on your cash and contactless collections; keep clean, linked records so claiming is quick and safe; and review the last four years for anything you have missed before the window closes. CharityIQ can help here — keeping track of declarations and preparing claims grounded in your own records, with a person checking before anything is submitted — but the steps above are free and available to every charity. Start with the Gift Aid calculator to see what your donations are worth.
If you take one thing from this handbook, make it a simple routine. First, get recognised by HMRC for tax and enrolled for Charities Online, if you are not already. Second, ask every eligible donor for a Gift Aid declaration, and use enduring declarations so you only have to ask once — build the ask into your donation form, your website, your events and your thank-you process. Third, keep clean records that link each donation to a valid declaration, and store the declarations somewhere you can find them. Fourth, claim regularly through Charities Online, in monthly or quarterly batches, and add GASDS for the cash and contactless collections you cannot attach a name to. Fifth, once a year, review the last four years for anything you have missed before the four-year window closes, and check any donations that come with a benefit against HMRC’s current rules. None of these steps is difficult, and together they make sure your charity receives every pound it is entitled to, correctly and safely. Gift Aid rewards the organised: the charities that claim the most are rarely those with the most donors, but those that ask for a declaration every time and keep good records. For a small charity, that quiet discipline can add a quarter to a large slice of its voluntary income, year after year, for no extra fundraising at all — which is why it is worth getting right.
