Grant Thornton offers a timely, cost effective, managed iXBRL tagging service for company financial statements and tax returns. If the Irish Revenue or HRMC iXBRL tagging requirements apply to your company then our service could be the solution for you. To read more about iXBRL please see here.

Who does iXBRL apply to?


Filing of financial statements in iXBRL format is mandatory for all corporation tax payers with the exception of companies who meet all three of the following criteria:

  • balance Sheet total ≤ €4.4m;
  • annual turnover ≤ €8.8m an; and
  • average number of employees ≤ 50.


All companies required to file a corporation tax return must file the tax return itself, the supporting tax computation and related statutory financial statements electronically using iXBRL.

How does our iXBRL tagging service work?

The scope, cost and timeline of our service will be agreed with you (the client) at the outset and outlined in a signed engagement letter. The financial statements and or corporation tax returns will be tagged by our specialist iXBRL team. An initial and final independent quality review will be completed by our management team prior to delivering your tagged documents to you.

How much does iXBRL tagging cost?

The cost of our iXBRL tagging service is dependent upon the volume and size of financial statements and/ or tax returns to be tagged. We do offer volume discounts to clients for tagging multiple sets of company financial statements. Please feel free to contact one of our iXBRL team for a quote.
