The form is supposed to be completed and signed by the contributor and returned to the receiver of the donation. They must keep these documents for six years after they have claimed the gift aid. The contributor must be an individual and the receiver must be recognized as a charity organization or as a community amateur sports club (CASC) for tax purposes. There are two types of Gift Aid Forms. Despite the fact that their contents are quite similar they are supposed to be used in different situations. The choice of which document to use will depend on whether the giving party would like to Gift Aid one contribution or several of them. Charity Gift Aid Declaration Single Donation. This kind of Gift Aid Declaration is supposed to be used when the contributor agrees to Gift Aid a single donation they have made to the receiver designated in the declaration. Charity Gift Aid Declaration Multiple Donation. Contributors can use this form if they want to Gift Aid the donation they have made and all of their future donations to this receiver. The form can also be used if the contributor wishes to Gift Aid the donation they have made during the last several years to this receiver.
