SureFile Accounts supports and provides assurance
on the creation of accounts in iXBRL





Now with support for the FRC 2023 Taxonomy


SureFile is an independent and reliable service developed by the UK’s leading XBRL experts which gives vital support to companies and accounting firms now that the era of HMRC's minimum tagging concession is well and truly over and we move into full tagging with the new FRC accounts taxonomies.

SureFile provides a range of tests to help preparers check and improve tagging in iXBRL. It gives an easy and very cost-effective means of strengthening assurance on the quality of tagging. Surefile Accounts:

  • Helps preparers to avoid tagging gaps and errors that are likely attract attention from HMRC or the Irish Revenue – thus reducing the risk of enquiries.
  • Gives clear and informative error messages and guidance on fixing any problems.
  • Saves valuable time and effort in creating valid and high quality iXBRL accounts.
  • Helps avoid costly last-minute problems revealed only when accounts are put into a Corporation Tax Return and filed to HMRC or the Irish Revenue.

SureFile uses the same basic software as HMRC and Companies House to validate XBRL accounts. However, on top of this, SureFile has built a range of tests to check the quality of tagging.


It provides clear and informative reports to guide users in fixing problems (see left). These highlight the locations in accounts where tagging needs checking or amending. SureFile also uses clear language, avoiding the technical jargon and baffling obscurity of messages from government XBRL systems.




SureFile is a low cost service. Accounts preparers can sign up online for a single test attempt or save money by subscribing for a batch of tests. Click Subscribe for more information.
