Revenue has published a technical note for software developers and those who are using conversion tools to prepare accounts in iXBRL. The note may also be of interest to practitioners looking to increase their understanding of iXBRL technologies.

The technical note explains:

• What a Taxonomy is and what taxonomies are acceptable to Revenue
• What a context entity identifier is and what entity identifier schemes will be accepted by Revenue
• What validations rules will apply to financial statements submitted to Revenue in iXBRL format

As we have reported previously in tax.point, from 23 November 2012, financial statements in iXBRL format will be accepted in Revenue Online Service (ROS). From that date all corporation taxpayers will have the option of uploading their financial statements in iXBRL. Initially the filing of financial statements in iXBRL will be optional but will be mandatory for all corporation taxpayers commencing with taxpayers dealt with in Revenue's Large Cases Division from October 2013. Income taxpayers will have the option of filing in iXBRL on ROS from 1 January 2013.

Revenue's technical note is published on the dedicated iXBRL section of their website www.revenue.ie under Home – About ROS – iXBRL.
