Submission of Financial Statements in iXBRL
Revenue is rolling out mandatory filing of iXBRL Financial Statements for Corporation Tax Payers in stages. The first group, cases dealt with in the Large Cases Division (LCD) are required to file iXBRL Financial Statements in respect of all Corporation tax returns submitted on or after 1 October 2013, in respect of accounting periods ending on or after 31 December 2012.
Phase 2 extends mandatory iXBRL filing to all Corporation Tax Payers other than those meeting the three criteria below. This will apply to Corporation Tax returns submitted on or after 1/10/2014 in respect of accounting periods ending on or after 31/12/2013. The three criteria for exclusion from this phase are:
- The balance sheet value of the company does not exceed €4.4 million;
- The amount of the turnover of the company does not exceed €8.8 million; and
- The average number of persons employed by the company does not exceed 50.
Please note that to be excluded from the Phase 2 filing obligation a company must meet all three criteria.
Phase 3 will involve all remaining Corporation Tax Payers. It is intended that this will commence in 2015.
Companies not yet subject to mandatory iXBRL filing may still do so on optional basis. We strongly encourage companies to use either the optional filing period or the test filing facilities to ensure they are fully prepared for mandatory filing.
iXBRL has been available to Income Tax filers on an optional basis since 1 January 2013.
What is iXBRL
XBRL (eXtensible Business Reporting Language) is a language that allows the presentation of financial information in a computer readable format. XBRL is increasingly being adopted by both businesses and regulators world-wide. iXBRL, or 'inline' XBRL, is a more recent version of the language which allows human-friendly presentation of XBRL documents.
Revenue is committed to full and open consultation with all our stakeholders on this project aimed at ensuring that taxpayers, agents and Software Vendors are aware of and prepared for the transition to iXBRL usage. Aspects of this consultation/communication process include:

Taxonomies - Revenue has opted to accept Irish GAAP accounts tagged according to the UK GAAP taxonomy supplemented by an "Irish extension" which bridges the differences between UK and Irish GAAP. The "Irish extension" taxonomy was published by XBRL Ireland in June 2012 and can be viewed or downloaded here. It is now being incorporated into standard accounting software packages available on the Irish market. Revenue will also accept IFRS accounts tagged according to the UK IFRS taxonomy. An Irish extension to UK IFRS is in development.
Validation - Uploaded iXBRL financial statements will be subject to validation. Initially, the validation will be restricted to a limited number of fields such as period start and end date and the current mandatory accounts menu fields. If any submissions fail the validation process, a notification will be sent to the customer’s ROS inbox informing them of the errors. Customers will then have the option to amend and re-submit their accounts.
