Apologies for the trouble with your CT600 submission. We've identified and fixed the underlying bug.

What happened: Your session expired between filing your accounts (26 Dec) and submitting CT600 (12 Jan), which caused the tax return to be sent without the required documents attached.

To complete your filing:

1. Log in and go to Dashboard → CONTRAFLOW DYNAMICS LTD → YE 31/03/2025

2. Click "Preview & Submit" to regenerate your documents

3. Submit CT600 immediately after preview

Your accounts are already accepted by Companies House, so only the CT600 needs to be submitted to HMRC.
