Almost all charity shops sell on their unsold textiles (i.e. unfashionable, stained or damaged fabric) to textile processors. Each charity shop saves an average of 40 tonnes of textiles every year, by selling them in the shop, or passing them on to these textile merchants for recycling or reuse. This grosses to around 363,000 tonnes across all charity shops in the UK; based on 2010 landfill tax value at £48 per tonne, the value of textiles reused or passed for recycling by charity shops in terms of savings in landfill tax is £17,424,000 p.a. Gift Aid is a UK tax incentive for individual donors where, subject to a signed declaration being held by the charity, income tax paid on donations can be reclaimed by the charity. Although initially intended only for cash donations, the scheme now (since 2006) allows tax on the income earned by charity shops acting as agent for the donor to be reclaimed.
