Accounts and tax returns for private limited companies
Filing accounts and tax returns
You file your accounts with Companies House and your Company Tax Return with HM Revenue and Customs (HMRC).
You’ll need to use commercial software to file your Company Tax Return with HMRC. There’s a list of commercial software suppliers you can use to file your Company Tax Return.
You can use the paper form (CT600) to file your tax return with HMRC if either:
- you cannot file online because you have a reasonable excuse
- you want to file in Welsh
Filing your accounts and Company Tax Return at the same time
You may be able to file them together if you have a private limited company that does not need an auditor.
You can look for accounting software or a commercial software provider that lets you file both at the same time.
