Who should submit financial statements in iXBRL format with HMRC?
The statutory accounts filed along with the company tax returns need to be in iXBRL format if they are required to be prepared under any of the following legislation:
In addition, overseas companies resident in the UK must deliver the accounts required by a notice to deliver a return in iXBRL.
Also a company not resident in the UK, but carrying on a trade in the UK through a permanent establishment, branch or agency in the UK, must deliver any trading and profit and loss account and any balance sheet of the UK establishment, branch or agency required as part of its return in iXBRL format.
In other circumstances, accounts can be sent as either iXBRL or PDF files.
