Companies House


Filing iXBRL accounts at Companies House


Companies House can receive and process company accounts produced in iXBRL format, and more software package providers are making this available.

If your accounting software package produces UK GAAP accounts in iXBRL format, there are simple ways to submit them to Companies House. You can do this for audited and unaudited full accounts, or abbreviated accounts in two ways:

  1. directly, from enabled accounts production software, or
  2. by uploading them to Companies House via a third party web-based service or locally installed software package.

Important note: to file accounts via software you will need a Companies House online filing presenter account. You can use your existing presenter account if you have one, or read our iXBRL FAQs on how to apply for one.

  • No postage costs
  • Faster, more secure delivery with immediate acknowledgement of receipt*
  • Automatic confirmation of acceptance or rejection*
  • Reduced risk of late filing penalties.

*ask your software provider how notifications will be delivered
