This is a tax to the English government. Stamp Duty does not appear as part of the order when you enter a buy order but will be deducted from the bank account on the settlement date. When you buy shares on the London Stock Exchange, you will be charged 0.50 per cent of the trade amount in addition to the brokerage fees. If the share is registered in Ireland, however, Stamp Duty will be 1 per cent. Please note that Stamp Duty is only paid in connection with buying and not with selling.
