The way that the current Gift Aid scheme is structured means that only about half of the potential GA tax refunds are claimed. This is mainly because the most frequently-used forms of fundraising do not easily lend themselves to collecting Gift Aid declarations. Even major public appeals with masses of television coverage (LiveAid, Comic Relief, DEC’s Tsunami, Christian Aid Week etc) find it difficult to obtain a really substantial proportion tax-effectively.
Research commissioned by HMRC shows that the donors give most often through collecting tins 54%, raffles 52%, buying charity goods 43%, sponsorship 37%, house-to-house 34%, fundraising events 26%, entrance or membership fees 23%, and church collections 20%. These are predominantly spontaneous one-off giving methods for smaller donations, for which charities find it incredibly difficult to collect valid Gift Aid declarations (GADs). Several of these fundraising methods are not voluntary donations (eg raffles) or provide a personal benefit to the donor, so are not eligible for GA. It is estimated that overall about two-thirds of charitable donations comes through these methods, of which perhaps only 10% - 20% are made tax-effectively.
