Charitable giving legislation introduced in 2000 allows personal tax relief when you donate shares, securities and 'real property' (land and buildings) to charity. When you do this you could benefit from tax relief as follows:
Income tax relief
If you are a higher rate taxpayer and you give us shares worth £20,000, you will get a tax saving equal to 40% of £20,000, or £8,000. If you are a basic rate taxpayer you could claim 20% of £20,000, or £4,000.
Capital gains relief
Gifts of shares to a charity are exempt from capital gains tax. If, for example, you had already used up your annual capital gains allowance and you give us shares worth £20,000 that originally cost you £5,000, your tax saving would be 40% of £15,000 or £6,000.
Gifts of appreciated securities can therefore give both income and capital gains tax benefits, and may allow you to make a significant gift at minimal cost to you.
