STSM013010 - Introduction to Stamp Duty on shares and Stamp Duty Reserve Tax (SDRT): Stamp duty rates: Stamp Duty - the standard rate
A transfer on sale of stock or marketable securities is subject to a 0.5% Stamp Duty charge, calculated by reference to the amount or value of the consideration paid.
Where the amount or value of the consideration for the sale is £1,000 or under, no 0.5% Stamp Duty charge will apply if the instrument contains a certificate of value (para 1(3A) of Sch.13 to FA1999). A certificate of value is a statement that the transaction effected by the instrument does not form part of a larger transaction or series of transactions in respect of which the amount or value, or aggregate amount or value, of the consideration exceeds that amount. An instrument representing a share sale for consideration of £1,000 or less which does not contain a certificate of value is subject to a 0.5% Stamp Duty charge.
