COM130175 - Returns / notices: notices and returns: HMRC CT600 online application

To enable smaller companies and agents to fulfil their obligation to deliver their returns online without having to buy third party software, HMRC provides an online version of the form CT600 which is available through the Corporation Tax Online Service.

The application enables companies to submit supplementary pages CT600A, CT600E and CT600J.

If a company needs to complete any of the other supplementary pages, it cannot deliver a return online using the HMRC CT Online application and it will need to use a commercial software package.

The CT View Returns application allows you to view all Forms CT600 and their attachments submitted online.

You can also view the CT600 element of the return information in COTAX Function DRTN (Display Return Data).
