Please note: We do not provide Accounts spreadsheets for you to download and fill in.
You need to attach a PDF / iXBRL document. Normally you will have accounts to go with the CT600. If you do not have these because your company is dormant or has ceased operation, you must spell out the reason for the absence of the accounts in the CT600 spreadsheet.
Up until April your accounts and the computation documents could be in either an iXBRL or PDF format. On and after April these two documents can only be e-filed in an iXBRL format.
Currently, we do not convert your accounts documents (Excel spreadsheet) to a PDF or iXBRL format. You need to use iXBRL software to do this. When you have converted the data into an iXBRL format you can upload it to our server and we will e-file it for you, together with other documents, to the HMRC.
