What is iXBRL, and accounts tagging?

XBRL is 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.


For further information, and other iXBRL or accounts tagging queries, please see our FAQ document, prepared by our dedicated iXBRL team.


How we can help

KPMG  is now offering its XBRL Conversion Services to Republic of Ireland companies. Our XBRL Conversion Service, 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 Customs (HMRC) in the UK for accounts conversion to iXBRL. HMRC introduced mandatory electronic filing of iXBRL tax computations and returns along with iXBRL financial statements for all companies from April 2011.


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.

History of iXBRL

Towards the end of 2012, the Revenue announced its plans to introduce iXBRL into the Irish tax compliance process. 


In July 2012 Revenue announced that from 23 November 2012 all companies would have the option to file iXBRL financial statements with Revenue and 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 made an important announcement regarding non-LCD companies. 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 will not apply to entities who meet the proposed audit exemption criteria in the Companies Bill 2012 (balance sheet total not exceeding €4.4m and turnover not exceeding €8.8m and average employee numbers not exceeding 50). These ‘exempt’ companies will be mandated in 2015 at a date still to be decided by Revenue.
