How to claim Gift Aid correctly 

Gift Aid boosts every eligible donation; it also creates personal responsibilities for donors and strict process duties for charities. Done well, Gift Aid adds 25p for every £1 donated; done badly, it risks clawback, penalties, or wasted income that could have reached your cause.  

Gift Aid today: the rules that shape every claim 

Gift Aid only applies when a UK-recognised charity or CASC receives a voluntary gift from an individual and holds a valid declaration for that donor. The declaration must name the charity, record the donor’s full name and home address, identify the gift or gifts covered, and confirm that the donor has paid enough UK Income Tax or Capital Gains Tax to cover the reclaim. If the donor has not paid enough tax, HMRC will look to the donor for the shortfall. The donor’s first responsibility, therefore, is to ensure that they have paid (or will pay) sufficient tax to cover the claim – and then to ensure that the documentation is completely correctly, and copies retained in case of HMRC enquiry These are the foundations of how to claim Gift Aid correctly. If the donor has not paid sufficient tax to cover the claim, it will be up to them and not the charity to pay the shortfall to HMRC. 

It is important to note a recent change – from April 2024, non-UK charities and CASCs no longer qualify for UK charitable tax reliefs, which means donations to EU or EEA charities do not attract UK Gift Aid. That change followed a transition period and is now embedded in policy; it affects donors with cross-border giving patterns and any charity that previously relied on EEA recognition.  

Declarations and record-keeping: small details that protect your claim 

A declaration stands until cancelled if it covers ongoing gifts; if a donor changes their name or address, the charity can note the change and keep the original declaration on file. Most charities must keep Gift Aid records for six years after the end of the accounting period they relate to; enduring declarations should be kept permanently while gifts continue. Clear records make it easier to show how to claim Gift Aid correctly should HMRC ask questions later.  

Take care when you’re receiving something of value in return 

A donation must be a genuine gift. If a donor receives more than permitted level of benefits in return, the payment will not qualify as a Gift Aid donation. Since April 2019, the rules have allowed benefits of up to 25% on the first £100 and 5% on the balance above that, capped at £2,500. In some cases, charities can split the payment, treating part of a payment as the purchase of the benefit and the remainder as a Gift Aid donation, provided this is clearly documented. This can apply to membership packages, event tickets, or auctions. For large complex donations, it is always best to seek professional advice.  

Higher-rate relief and Self-Assessment: don’t leave money behind 

Charities reclaim at the basic rate, but donors who pay income tax at the 40% higher rate or 45% additional rate can further relief through Self-Assessment or a PAYE code change. Donors who fall into Scottish rates should check that they have paid enough UK-wide tax to support claims across all their gifts.  

Carry-back elections: timing that rewards planning 

A donor can treat gifts as if they were made in the previous year, but only if the claim appears in the original return for that earlier year – so the gift will normally have to be made before 31 January when the tax return is due for submission. HMRC will not accept a first claim or an increased claim through an amended return; this rule catches many donors who try to optimise late. If carry-back matters, plan early and file the original return with the full claim in place.  

Waived refunds and loan repayments: when a “no-refund” becomes a gift 

Where donors waive ticket refunds or loan repayments to help a charity, HMRC has confirmed that such waivers can qualify for Gift Aid if formal requirements are met and records are kept. This route proved valuable during event cancellations and remains part of the landscape.
