What is Stamp Duty?

For shares over £1,000, the J30 stock transfer form is required to be stamped by HM Revenue and Customs (HMRC). The payment for this is known as stamp duty and is currently 0.5% of the share amount, rounded to the nearest £5. 

For example, to transfer shares valued at £1,800, 0.5 x 1800 = £9.00 so a £10 stamp duty fee is payable.
