How to file accounts online

You’ll need a Companies House password and authentication code to file your company’s accounts online.

If you have a private limited company that does not need an auditor, you could use the company accounts and tax online (CATO) service to file your Companies House accounts and HMRC company tax return together.

You can send us most types of accounts using third-party software.

It takes longer to process paper documents sent by post.
