Advisers who file stamp duty land tax returns using a CD ROM or 2D barcode should be aware that HMRC will not accept returns filed this way after 1 November 2008.
Returns can instead be filed using HMRC's Stamp Taxes Online, or - in Scotland only - using Registers of Scotland's Automated Registration of Title to Land service.
The rest of the UK also has the option of using third party software.
Visit the HMRC website for further information.
