HMRC had asked for views on increasing the amount of XBRL tagging when the transitional period expires at the end of March 2013. All responses agreed that there should be no major extension of the list of specified information from April 2013. HMRC has accepted this view and the tagging requirement will not change in April 2013.
HMRC is working with software suppliers and other representatives to make limited changes to the list from autumn 2013. There will be a single requirement for detailed profit and loss account tags, whether appearing in the accounts or the tax computations, and an improvement to the structure of the computations tags. Beyond that, there will be no major change without full consultation.
