Filing your Companies House accounts

Rules and requirements on filing annual accounts at Companies House for companies registered in the UK.



This guidance is for directors, secretaries and persons acting as advisers to UK registered companies. It covers the rules governing the filing of accounts for UK registered companies.

All companies must file annual accounts with Companies House - even if you’re dormant or not trading.

File online

File your company’s accounts online.

It’s taking much longer than usual to process paper documents sent to us by post.

What you can file online

You can use our Companies House Service, or WebFiling to send us some accounts types.

You’ll need a Companies House password and authentication code. You can register for online filing if you do not have them.

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.
