iXBRL: Tagging financial documents for Irish Revenue & HMRC compliance 

Irish Revenue announced in July 2012 that the submission of iXBRL financial statements would be mandatory for all companies dealt with by the Large Cases Division  ("LCD") of Revenue in respect of tax returns filed on or after 1 October 2013, relating to accounting periods ending on or after 31 December 2012.

In June 2013 Revenue announced that the submission of iXBRL financial statements will be mandatory for non-LCD companies in respect of tax returns filed on or after 1 October 2014, relating to accounting periods ending on or after 31 December 2013. This mandation date does not apply to entities who meet all three of the iXBRL exemption criteria (balance sheet value not exceeding €4.4m and turnover not exceeding €8.8m and average employee numbers not exceeding 50). These ‘exempt’ companies will be mandated at a date still to be decided by Revenue.


In the UK, HMRC introduced mandatory electronic filing of iXBRL tax computations and returns along with iXBRL financial statements for all companies from April 2011. 


What is iXBRL and accounts tagging?

iXBRL is inline eXtensible Business Reporting Language.


This is a language that allows the presentation of financial information in a computer-readable format.  This is achieved by tagging each piece of financial information with a label that identifies it in terms of standard accounting or tax concepts.


How KPMG can help

KPMG offers its iXBRL conversion services to Republic of Ireland and United Kingdom companies.  Over the past four years our iXBRL accounts conversion team with a local unit based in Belfast, has already tagged thousands of UK company accounts using its XME software which is recognised by HM Revenue and Customers (HMRC) in the UK for accounts conversion to iXBRL. 


With Irish Revenue's requirement to submit iXBRL financial statements, our team has also tagged and converted thousands of financial statements for Large Cases Division ("LCD") and non LCD companies over the past year.


KPMG's dedicated iXBRL team of experts have developed a suite of iXBRL solutions and services to help businesses adapt to the changes in an easy and cost-effective manner.
