Gift Aid Declaration (England & Wales)

Gift Aid is a UK government scheme that enables registered charities and Community Amateur Sports Clubs (CASCs) to reclaim basic-rate Income Tax on donations made by eligible UK taxpayers. The legal basis is found in the Income Tax Act 2007 ss.413–430, which provides that where a qualifying donation is made by an individual who is a UK taxpayer, the charity can reclaim the basic rate of tax (currently 20%) directly from HMRC. Because tax is calculated on the gross donation, the charity effectively receives 25p for every £1 donated — a £1 donation grosses up to £1.25, of which 20% (25p) is reclaimed from HMRC. For the donor, there is no cost beyond the original donation. For higher-rate (40%) and additional-rate (45%) taxpayers, further personal tax relief is available: a higher-rate taxpayer can claim an additional 20% relief through their Self Assessment tax return, and an additional-rate taxpayer can claim 25% additional relief, effectively reducing the net cost of giving significantly. Gift Aid is one of the most tax-efficient ways to donate to charity in the UK. The scheme was introduced by the Finance Act 1990 and significantly reformed by the Finance Act 2000 to remove the minimum donation threshold. Charities must be recognised by HMRC and registered with the Charity Commission under the Charities Act 2011. They must keep records of all Gift Aid declarations for inspection by HMRC for at least six years after the last claim to which the declaration relates.

To make a valid Gift Aid declaration under the Income Tax Act 2007 s.416, a donor must meet two fundamental requirements. First, the donor must be a UK taxpayer — that is, they must pay UK Income Tax and/or Capital Gains Tax during the tax year in which the donation is made. This includes individuals who are employed (paying tax through PAYE), self-employed (paying tax through Self Assessment), or retired (paying tax on pension income, savings interest, or other income above the personal allowance, which is £12,570 for 2024/25). Second, and critically, the total amount of Income Tax and Capital Gains Tax paid by the donor in the relevant tax year must be at least equal to the total amount of Gift Aid that all charities and CASCs will reclaim on the donor's donations in that year. This is the tax paid requirement under s.416(1)(c). If a donor's tax paid falls short of the Gift Aid reclaimed, the donor is personally liable to pay the shortfall to HMRC. This can occur for donors whose income fluctuates, who receive the Marriage Allowance transfer, or who are non-taxpayers incorrectly completing declarations. Donors who are non-taxpayers — for example, those whose income is entirely below the personal allowance — must not make Gift Aid declarations. Completing a Gift Aid declaration as a non-taxpayer is a criminal offence. Overseas donors, including those with dual residency, can make declarations only if they pay sufficient UK Income Tax or CGT to cover the reclaim.

Yes, a Gift Aid declaration can cover past donations as well as future ones, subject to specific time limits set by HMRC under the Income Tax Act 2007 and the Taxes Management Act 1970. When a donor completes a Gift Aid declaration that includes past donations, the charity can reclaim Gift Aid on qualifying donations made in the current tax year and up to four preceding tax years, provided the donor was a UK taxpayer and paid sufficient tax in each of those years. For example, a declaration signed in 2024/25 could potentially cover qualifying donations going back to 2020/21. However, the charity must have records of those past donations — including the date, amount, and method of each donation — to submit a valid claim. The six-year time limit for HMRC claims under s.34 of the Taxes Management Act 1970 applies to Gift Aid reclaims. Importantly, the donor must have been an eligible UK taxpayer during each tax year in which past donations were made. If the donor was a non-taxpayer in any year, Gift Aid cannot be claimed for donations made in that year even under a retrospective declaration. The charity is responsible for verifying the donor's eligibility and for accurately calculating the amount to reclaim. HMRC may audit Gift Aid claims and charities that make incorrect claims face penalties, interest, and repayment obligations. Donors should retain their declaration for their own records and inform the charity promptly if their tax status changes.

Charities holding Gift Aid declarations are data controllers under the UK General Data Protection Regulation (UK GDPR), which is retained in UK law by the European Union (Withdrawal) Act 2018 and supplemented by the Data Protection Act 2018. The charity must process the donor's personal data — including name, home address, and postcode — lawfully, fairly, and transparently under Article 5 UK GDPR. The lawful basis for processing is typically legitimate interests (Article 6(1)(f)) or the performance of a contract (Article 6(1)(b)) where the donation agreement implies the data is required for Gift Aid processing. HMRC requires charities to retain Gift Aid declarations and associated records for at least six years after the last Gift Aid claim to which the declaration relates, in accordance with HMRC Gift Aid guidance and the Taxes Management Act 1970. Charities must not use Gift Aid declaration data for unrelated purposes (such as unsolicited marketing) without a separate lawful basis, such as the donor's explicit consent under the Privacy and Electronic Communications Regulations 2003 (PECR) for electronic marketing. Charities must provide donors with a privacy notice explaining how their data is used, the legal basis, retention period, and the donor's rights under UK GDPR, including the right to access, rectification, and erasure (though erasure rights are limited by the legal obligation to retain records for HMRC). The Information Commissioner's Office (ICO) has published specific guidance for charities on data protection compliance in fundraising contexts.

Yes. The Gift Aid declaration mechanism operates at the basic rate of Income Tax (20%), enabling the charity to reclaim 25p per £1 donated. However, donors who pay Income Tax at the higher rate (40%) or the additional rate (45%) under the Income Tax Act 2007 are entitled to claim further personal tax relief on their Gift Aid donations. For a higher-rate taxpayer donating £100 cash, the grossed-up value of the donation is £125. The charity reclaims £25 (basic rate relief) from HMRC. The higher-rate taxpayer can then claim an additional £25 (the difference between the 40% higher rate and the 20% basic rate, applied to the £125 gross donation) through their Self Assessment tax return under s.520 of the Income Tax Act 2007. This reduces the effective cost of the £100 donation to £75 for the higher-rate taxpayer. For additional-rate taxpayers (45%), the additional relief is £31.25, reducing the effective cost to £68.75. This additional relief must be claimed by the donor through Self Assessment — it is not automatically paid by HMRC. Donors who have ceased filing Self Assessment returns can claim this relief by contacting HMRC directly using form R40 or by phoning HMRC's helpline. It is important that the donor records their Gift Aid donations accurately on their Self Assessment tax return (SA100, Question 5) to confirm the correct relief is applied. Overstating Gift Aid donations to inflate tax relief claims is a criminal offence under the Fraud Act 2006.

A donor may cancel a Gift Aid declaration at any time by notifying the charity in writing. There is no prescribed form for cancellation under the Income Tax Act 2007 or HMRC guidance — a simple letter or email stating that the donor wishes to cancel their Gift Aid declaration is sufficient, provided it clearly identifies the donor and the charity concerned. The cancellation takes effect prospectively from the date the charity receives the written notification — it does not affect Gift Aid already validly claimed on donations made before the cancellation date. This means the charity retains the right to claim (or retain) Gift Aid on all qualifying donations made up to the point of cancellation, subject to the normal time limits. Donors are legally obliged to notify the charity of cancellation in the following circumstances: if they cease to be a UK taxpayer (for example, because their income falls below the personal allowance, they become non-UK resident, or they retire on a low income); if their tax paid in any year is likely to be less than the Gift Aid that will be reclaimed on their donations; or if there is any material change in their tax status. Failure to notify the charity of a change in tax status, resulting in the charity making an invalid Gift Aid claim, does not automatically result in criminal liability for the donor but may require the donor to repay the overpaid tax to HMRC under assessment proceedings.
