For periods ending on or after 1st April 2014, HMRC have amended their e-Filing requirements and now expect returns to include an XBRL tagged DPL. Tagged DPL information must be included in either the Computation or the Statutory Accounts. In most cases, organisations will be expected to include the following attachments as part of their e-Filing submission:

  • iXBRL Tax Computation
  • iXBRL Statutory Accounts
  • iXBRL Detailed Profit and Loss Account – as part of the computation or accounts
