Gift Aid is an easy way to help your charity maximise the value of its donations, as you can reclaim tax from HM Revenue & Customs (HMRC) on its 'gross' equivalent - its value before tax was deducted at the basic rate. This is 20% from 6 April 2008. You can work out the amount of tax you can reclaim by dividing the amount donated by four. This means that for every £1 donated, you can claim an extra 25 pence.
