Section 86B Market Capitalisation
Section 86B provides for an exemption from Stamp Duty on a conveyance or transfer of stocks or marketable securities where the securities are admitted to trading on a "relevant market" and the closing market capitalisation of the company that issued the securities was below €1 Billion on 1 December in the previous year. In a case where the securities were admitted to trading after 1 December in the previous year, the exemption will apply if the expected market capitalisation was below €1 billion.
Tax and Duty Manual - Section 86B - Market capitalisation - has been updated in paragraph 3 to provide guidance on submitting a valid notification where a company holds more than one International Securities Identification Number (ISIN).
