October was the start date for HMRC’s acceptance of filings in accordance with the new Detailed Profit and Loss (DPL) taxonomies. The conversion of DPL financial statements to iXBRL won’t be mandatory immediately, as it applies to accounting periods ending only on or after 1st April 2014, so we may not see a deluge of filings for several months.
However, the good news is that Seahorse is there to help whenever you are ready to start filing. The new DPL taxonomies for UK GAAP and IFRS have been incorporated into the latest release of the product, so you can begin submitting DPL statements in iXBRL right now, or at least know that Seahorse will be ready to help once you decide to start DPL filing.
HMRC have also published an informative User Guide on the DPL taxonomies which can be found at: http://www.hmrc.gov.uk/softwaredevelopers/ct/dpl-guide.pdf
