Who needs file iXBRL Tagged Financial Statements ?

In Ireland, filing of iXBRL Financial Statements is mandatory for corporation tax payers, within 3 months of their CT due date (Revenue eBrief 75/16 available here), if they exceed any one of the following thresholds:

  • Balance Sheet Total €4.4 million
  • Annual Turnover €8.8 million
  • Average Number of Employees 50

The similarity with satisfying old Audit Exemption Thresholds but not iXBRL exemption, had been a source of confusion but now that these have changed (to BS €6million, T/O €12m, Ee’s same), it has at least been cut down.

Some other companies do have to file iXBRL tagged accounts where Revenue specifically request them.

All UK corporation tax payers have had to file iXBRL tagged financial statements since 2011, along with iXBRL tagged Tax Computations and Corporate Tax returns (CT600’s).

What’s happening to iXBRL tagging in Ireland in 2018 ?

Whilst definitive timescale has been put on when all remaining corporate entities will have to start iXBRL filing with their CT1’s, it will eventually happen.

That doesn’t mean however, that there has been nothing happening in iXBRL tagging in Ireland in 2018. Behind the scenes, Revenue have developed a ‘plug-in’ taxonomy that fits into the all existing FRS102/105, FRS101 and New EU IFRS taxonomies, that facilitates a deeper and more granular tagging of Detailed Profit and Loss Accounts.

In addition to this, mandatory tags have been introduced to correspond with the Detailed P&L categories found on the CT1 form.

This comes into effect from 1 August 2018 and I am pleased to announce that 123 XBRL are ready to tag under the new Revenue taxonomies (Revenue eBrief 80/18 available here).

I hope you have found the above information. You can place orders through our website at, where you can pay by Debit / Credit card or contact us directly at if you prefer to pay by Bank Transfer with your order.
