Please follow the below steps:
1) You first need to inform HMRC from your end separately that the Company is/going to be Ceased.
2) While creating an accounting period, you must check 'Is company ceased?'. If it was already done follow step 3.
3) Navigate to Accounts Production >> Settings >> Accounting Policy.
4) Check the box for 'Going Concern' and click on 'Edit' button.
5) Mention company ceasing details in 'Going concern' policy manually and 'SAVE' the details.
6) If you have already created the accounts report prior to this ceasing configuration as mentioned in the above steps, then you must regenerate the report.
