HM Revenue & Customs

How do I send my Company Tax Return online?

You need software to do this. If you represent a small company or organisation with straightforward tax affairs, you can use the HM Revenue and Customs (HMRC) free downloadable Corporation Tax online filing software. Otherwise, you can use one of the commercial software packages that has successfully passed HMRC's testing procedures.

You can find out about commercial software on the software and online forms forms page.
