Add a Checkbox to Opt In to the UK Gift Aid Tax-Incentive on Membership Checkout.
About the Add On
Gift Aid allows individuals who are subject to UK income tax to complete a simple, short declaration that they are a UK taxpayer (Wikipedia, 2015). If you dont know what Gift Aid is – you probably dont need this. This Add On allows you to add a checkbox to membership checkout so customers can opt in to Gift Aid.
