RE1855 - Gifts of Land, Buildings, Shares & Securities to Charity: amount of the relief

The amount that the donor can deduct in calculating their total income/ profit for tax purposes is the relevant value of the qualifying investment(s) at the date of disposal

Plus any incidental costs of making the disposal - eg broker’s fees,

Less the amount of any consideration received for the disposal or the value of any benefits received by the donor (or any person connected with them) in consequence of the gift.

In most cases that involve a simple gift the relevant value will be the market value of the asset. There is advice on how to work out the relevant value in other situations on the HMRC website at www.hmrc.gov.uk/charities/guidance-notes/chapter5/part1.htm
