Gift Aid is one of the most valuable tax reliefs available to UK charities. When set up and operated correctly, it adds 25p to every £1 donated at no cost to the donor. This guide covers the mechanics, the obligations and the edges where things go wrong.
What Gift Aid is worth: 25p for every £1 donated
A charity or community amateur sports club (CASC) claims 25p for every £1 donated. The gross donation is the gift divided by (1 minus the 20% basic rate), and the claim is basic-rate tax on that gross. The donor must have paid at least as much UK income tax or capital gains tax in the year as all charities will reclaim on their donations.
The worked example makes the arithmetic plain:
| Step | Amount |
|---|---|
| Donor gives | £100.00 |
| Gross donation (£100 ÷ 0.80) | £125.00 |
| Charity Gift Aid claim (25% of gross) | £25.00 |
| Total received by the charity | £125.00 |
Use the Gift Aid calculator to work out the repayment on any donation amount or batch of donations.
Gift Aid is available to charities recognised by HMRC and to CASCs. It is not available to community interest companies (CICs), which are not charities and receive no charity tax reliefs. See the Gift Aid service page for how we can help you set up and manage your programme.
Who can claim and the HMRC recognition step
Charity Commission registration alone does not deliver Gift Aid. A charity must also be recognised by HMRC before it can make any claim. These are two separate processes. Most newly registered charities apply for HMRC recognition at the same time as or shortly after Commission registration, but recognition can take several weeks and no claim should be made in the intervening period.
CASCs registered with HMRC can also claim Gift Aid on donations. Unincorporated associations, some membership organisations and other bodies may qualify as CASCs but should confirm their status with HMRC before proceeding.
Once recognised, the charity submits repayment claims through HMRC's Charities Online service using form ChR1. Claims can aggregate multiple donors and multiple accounting periods, subject to the record-keeping rules below.
Valid declarations: what they must contain and how long to keep them
A Gift Aid declaration is the donor's written (or oral, if HMRC-approved) confirmation that they want Gift Aid to apply and that they are a UK taxpayer. HMRC requires every declaration to include all of the following:
- The charity's name
- The donor's full name
- The donor's home address (including postcode)
- What donations it covers (the specific gift, all future gifts, or a retrospective catch-all)
- A statement that the donor wants Gift Aid to apply
- The explanation that the donor must pay at least as much UK income tax or capital gains tax as will be reclaimed on their donations in that year
A declaration that omits any of these elements is invalid. Claiming on an invalid declaration means repaying the tax, plus possible interest and penalties.
For a checklist of correct wording and template language, see the blog post on Gift Aid declaration wording.
How long must you keep declaration records?
The retention rule depends on the type of declaration:
- Time-limited declarations (covering a single gift or a defined period): keep for 6 years from the end of the accounting period in which the last donation covered by that declaration was made.
- Enduring declarations (covering all future gifts until the donor cancels): keep permanently, or at least 6 years after the donor cancels or dies.
HMRC can request records at inspection. A charity that cannot produce a declaration for a claimed donation will be required to repay the Gift Aid amount.
Making a claim to HMRC: process overview
Claims are submitted online via HMRC's Charities Online service. The charity logs in, selects the accounting period and uploads a schedule of donors, donation dates and amounts. HMRC typically makes repayment within 5 weeks of a valid online claim, though the actual time varies.
Key operational points:
- You can combine multiple donors and multiple dates in a single claim schedule.
- You must hold a valid declaration for each donor before submitting the claim (not after).
- Aggregated claims (under £500 per donor per tax year) are permitted, reducing the schedule size for high-volume, low-value programmes.
- Corrections to submitted claims are made by submitting an amended claim or an adjustment claim, not by phone.
How far back can a charity claim? HMRC's published guidance does not set out a definitive statutory time limit on the charity side, so treat this as genuinely unsettled rather than assuming a deadline. Do not rely on an informal figure that circulates in sector guidance. If you are catching up on unclaimed Gift Aid from prior years, confirm the applicable deadline directly with HMRC or with an adviser familiar with your specific position before submitting.
The donor tax-paid condition: what happens when it fails
Gift Aid only works if the donor has paid at least as much UK income tax or capital gains tax in the relevant tax year as all charities will reclaim on their donations. This is the donor's responsibility to self-certify in the declaration, but the charity bears the risk if the condition is not met.
Common failure scenarios:
- The donor is a non-taxpayer (for example, a child, a retired person on savings income below the personal allowance, or a spouse whose income is too low).
- The donor's total Gift Aid donations across all charities exceed their total UK tax bill for the year.
- The donor has moved abroad and is no longer a UK taxpayer.
If HMRC discovers that Gift Aid was claimed on donations where the condition was not met, it recovers the tax from the charity, not the donor. The charity's only recourse is to seek reimbursement from the donor, which is rarely practical.
Practical steps to manage this risk: include the tax-paid wording prominently in every declaration; remind donors in your annual Gift Aid communication to notify you if their tax position changes; cancel Gift Aid on donations from donors who inform you they are no longer taxpayers.
Donor benefit limits
A donor cannot receive a material benefit in return for a Gift Aid donation without the benefit being tested against HMRC's value limits. If the benefit exceeds the limit, the entire donation loses Gift Aid, not just the excess. The limits are set by HMRC guidance:
| Donation amount | Maximum benefit value |
|---|---|
| Up to £100 | 25% of the donation |
| Over £100 | £25 plus 5% of the amount above £100 |
| Any amount (annual cap per charity) | £2,500 aggregate in a single tax year |
Examples:
- A £50 donation with a £10 benefit: 25% of £50 = £12.50. Benefit is £10. Limit not breached. Gift Aid intact.
- A £200 donation with a £40 benefit: limit is £25 + 5% of £100 = £25 + £5 = £30. Benefit is £40. Limit breached. No Gift Aid on that donation.
- A donor gives £5,000 and receives £3,000 of benefits in a year: annual cap is £2,500. Entire position must be reviewed.
Value is what the recipient would pay on the open market, not what the charity paid to provide it. Free event tickets, thank-you gifts, membership privileges and advertising space are all potentially caught. If in doubt, value the benefit at its retail price and check against the table.
Higher and additional rate donors: the other side of the claim
The charity's 25p per £1 claim is only part of the Gift Aid story. Donors paying income tax above the basic rate are personally entitled to reclaim the difference between their rate and the basic rate on the gross donation, via Self Assessment or a tax code adjustment.
The worked example from HMRC for a £100 donation:
| Rate | Gross donation | Charity claims | Donor reclaims | Net cost to donor |
|---|---|---|---|---|
| Basic rate (20%) | £125.00 | £25.00 | Nil | £100.00 |
| Higher rate (40%) | £125.00 | £25.00 | £25.00 | £75.00 |
| Additional rate (45%) | £125.00 | £25.00 | £31.25 | £68.75 |
The donor's reclaim is calculated on the gross donation: for a 40% taxpayer, 40% minus 20% = 20% of £125 = £25. For a 45% taxpayer, 45% minus 20% = 25% of £125 = £31.25.
Scottish income tax note: Scottish income tax has its own rate bands (intermediate, higher and top rate) which differ from the rest of the UK. The donor-side reclaim calculation uses Scottish rates for Scottish taxpayers. However, the charity's own claim (25p per £1) is UK-wide and is not affected by where the donor lives or which rate they pay.
Charities can encourage higher-rate donors to claim their personal relief by including a reminder in acknowledgement letters, although the charity cannot make the claim on the donor's behalf.
GASDS: top-up payments on small cash donations
The Gift Aid Small Donations Scheme (GASDS) allows charities to claim a top-up payment equivalent to Gift Aid (25%) on small cash and contactless donations of £30 or less, without needing a Gift Aid declaration from each donor. This is particularly useful for collection boxes, street fundraising, and event buckets.
Use the GASDS calculator to work out the top-up on your eligible donations.
Key rules from HMRC's GASDS guidance:
- Donation cap: Up to £8,000 of donations per tax year are eligible (this is the donations cap, not the claim). The maximum top-up is therefore £2,000 per year (25% of £8,000).
- Per-donation limit: Each individual donation must be £30 or less. Donations above £30 cannot be included in a GASDS claim.
- Matching rule: GASDS donations claimed cannot exceed 10 times the donations on which a Gift Aid claim is made in the same tax year. If the charity claims Gift Aid on £500 of donations in a year, it can include up to £5,000 in GASDS. A charity with no Gift Aid claims in a year cannot make a GASDS claim at all (unless it qualifies under the community buildings rules below).
- Claim deadline: Claims must be made within 2 years of the end of the tax year in which the donations were collected. This is a hard deadline.
- No Gift Aid track record needed for donations collected on or after 6 April 2017.
Community buildings rules
Connected charities and charities that collect donations at community buildings (6 or more charitable events with 10 or more people attending) may be eligible for a separate £8,000 GASDS allowance per qualifying building, on top of the main allowance. These rules are detailed and require careful reading of the HMRC guidance before applying them. See the GASDS rules blog post for an overview and the full HMRC guidance for the definitive rules. Do not estimate entitlement from the high-level description alone.
Retail Gift Aid for charity shops
Charity shops that accept donated goods can operate the retail Gift Aid scheme under HMRC detailed guidance chapter 3, section 3.42. The mechanics are straightforward in principle: the shop acts as the donor's agent when selling donated goods, and the sale proceeds become a Gift Aid donation from the original donor.
HMRC approves two operating methods:
- Standard method: The donor is notified of their goods' sale value and given an opportunity to opt out before the Gift Aid donation is processed. Full donor records are maintained.
- Simplified method: Suitable for high-volume, low-value donations. Donors sign a global retail Gift Aid declaration covering all future shop donations; notifications are sent in aggregate at least once a year; donors can opt out at any time.
Both methods require a valid Gift Aid declaration from the donor (covering their shop donations specifically), correct agency documentation, and proper records. The benefit-limit rules described above do not apply because the donor is not receiving a benefit in the conventional sense: the goods belong to the donor and the shop is selling them on their behalf.
Retail Gift Aid can be a significant revenue stream for shops with a high donation throughput, but the administration requires care. Contact us via the Gift Aid service page if you are setting up or reviewing a retail Gift Aid programme.
When Gift Aid goes wrong
HMRC can open a Gift Aid compliance check at any time. Common triggers include high claim volumes relative to charity size, inconsistent or incomplete records supplied at inspection, and third-party reports. The outcomes range from minor corrections to full repayment demands plus interest and penalties.
The most frequent errors charities encounter:
- Missing or incomplete declarations: The charity cannot produce a valid declaration for every claimed donation. HMRC requires repayment of the Gift Aid on those donations.
- Donor benefit limit breach: Benefits (event tickets, thank-you gifts, membership extras) were not valued at market rate and exceeded the limit for those donations.
- Donor was not a taxpayer: The declaration was signed in good faith but the donor's tax position changed and the charity was not notified.
- Enduring declarations not updated: An old declaration does not include all required elements (for example, it pre-dates the address requirement) and is therefore invalid.
- GASDS matching rule not met: The charity claimed GASDS top-up on more than 10 times its Gift Aid-claimed donations in the same year.
- GASDS 2-year deadline missed: The claim was submitted more than 2 years after the end of the tax year in which the collections were made.
- Unauthorised claimants: A charity with HMRC recognition allows a connected entity (for example, a CIC or trading subsidiary) to be included in its claim. Only HMRC-recognised charities and CASCs can benefit from Gift Aid.
If you discover an overclaim, the correct step is to notify HMRC promptly and make a voluntary adjustment before they discover it. Voluntary disclosure consistently receives more favourable treatment than errors identified under compliance checks.
If your charity has unclaimed Gift Aid for prior years, or you are uncertain whether your current processes are HMRC-compliant, the Gift Aid service page explains how we can review your position and manage the catch-up process.
Frequently asked questions
How much does a charity get from Gift Aid?
A charity receives 25p for every £1 donated, paid directly by HMRC. A £100 donation becomes a £125 gross donation; the charity claims the £25 difference. There is no cost to the donor. See HMRC's Gift Aid page for the official statement.
Do we need a declaration for every donation?
Yes, for standard Gift Aid claims. One declaration can cover multiple future donations from the same donor (an enduring declaration), so you do not need a new form for each gift, but every donor from whom you claim must have a valid declaration on file. The exception is GASDS, where no declaration is needed for small cash or contactless donations of £30 or less.
How long must declarations be kept?
Time-limited declarations: 6 years from the end of the accounting period in which the last covered donation was made. Enduring (open-ended) declarations: permanently, or at least 6 years after the donor cancels or dies. See HMRC's declaration guidance.
What if the donor has not paid enough tax?
HMRC recovers the Gift Aid from the charity, not the donor. The charity's only recourse is to seek repayment from the donor, which is rarely practical. Manage the risk by including clear tax-paid wording in every declaration and reminding donors to notify you if their tax position changes.
Can we claim Gift Aid on donations from a company?
No. Gift Aid is only available on donations from UK individual taxpayers (and certain other structures such as partnerships acting on behalf of individual members). Corporate donations attract a different relief (the company deducts the donation from its profits for corporation tax purposes). HMRC's ChR1 claim form only accepts individual donors.
Can a CIC claim Gift Aid?
No. A community interest company is not a charity and receives no charity tax reliefs. Gift Aid is available only to HMRC-recognised charities and CASCs. See the CIC regulator's guidance for more on how CICs differ from charities.
How far back can a charity claim Gift Aid?
The HMRC guidance does not specify a definitive time limit on charity-side Gift Aid claims (as distinct from the GASDS 2-year deadline). If you are catching up on prior-year unclaimed Gift Aid, confirm the applicable position with HMRC or a specialist adviser before submitting. Do not rely on figures circulating in sector commentary without checking their source.
What is GASDS and do we need declarations for it?
GASDS (Gift Aid Small Donations Scheme) allows a 25% top-up on small cash and contactless donations of £30 or less, up to £8,000 of donations per year, without requiring a Gift Aid declaration. A matching rule applies: GASDS claims cannot exceed 10 times the same year's Gift Aid-claimed donations. Claims must be made within 2 years of the end of the relevant tax year. Use the GASDS calculator and see the GASDS rules blog post for detail.
Do charity shop sales qualify for Gift Aid?
Yes, through the retail Gift Aid scheme. The shop acts as the donor's agent; the sale proceeds of donated goods become a Gift Aid donation from the original donor. A valid retail Gift Aid declaration from the donor is still required, but the scheme avoids the need for a separate Gift Aid form at the time of each donation. Full details are in HMRC chapter 3 guidance (section 3.42).
How do higher-rate donors claim their relief?
Via Self Assessment: the donor declares their Gift Aid donations on their tax return and HMRC calculates the additional relief (the difference between their rate and the 20% basic rate, applied to the gross donation). Alternatively, HMRC can adjust the donor's tax code in-year. The charity cannot make this claim on the donor's behalf, but can remind donors in acknowledgement letters.
What records does HMRC expect at an inspection?
HMRC expects to see a valid Gift Aid declaration for every donation claimed; donation records cross-referenced to declarations; evidence that the donor tax-paid condition was checked; records of any benefits given to donors and the value test applied; and GASDS collection records (dates, amounts, event details if community buildings rules are used). Records should be retained for at least 6 years.
