Tax relief for charities and donors is expected to be worth £3bn in the tax year 2009/10, according to provisional figures from HM Revenue & Customs.
The figures predict the total amount of relief up to the end of the tax year. Tax relief for charities is expected to be worth about £2.37bn, and tax relief for donors is predicted to be about £680m.
HMRC expects the total value of tax relief to remain unchanged from the previous year, and to be only £40m more than the year before that.
The largest tax relief for charity is business rate relief, worth £1.09bn.Gift Aid and transitional relief repayments are predicted to be worth £951m, down from £967m in 2008/09.
Individual givers are expected to receive relief of £290m on inheritance tax and £290m in money returned to higher-rate taxpayers under Gift Aid.
Charities should also receive VAT relief worth £200m and stamp duty land tax relief worth £140m.
Hannah Terrey, head of policy and public affairs at the Charities Aid Foundation, said the figures were similar to those collected by her own organisation. But she added: "There is a lot more tax out there that charities would be able to reclaim."
