Complete the ‘Accounts’ section at the back of the CT600 form (see the bookmarks on the left). Then return to the opening page, click the ‘iXBRL’ button, and select ‘iXBRL Accounts’.
An onscreen receipt should confirm success.
Clicking the Download button on this receipt will open your browser and take you to your Ftax Account homepage (you may need to log in en route).
From your account homepage, you will be able to download the most recently generated iXBRL accounts or iXBRL computations files.
We only retain the most recent of each type of file for you to download.
Your iXBRL Accounts, along with your iXBRL Computations file, must be attached to the Ftax CT600 form before submitting online to HMRC (click ‘Attachments’ towards the bottom of the Bookmarks on the left).
Be very careful not to save the iXBRL file after it has been opened into a browser, as this will corrupt the data. Instead save the file to your desktop before attaching it to the Ftax CT600.
