COM41010 - Case records: responsible offices: list of cases in CT processing office

You can request a list of the COTAX cases for which your office is responsible. It can be tailored to your requirements using information stored in the data warehouse. The reports can include basic information for each case, such as

• The reference
• Company name
• Company address
• Ceased / Struck off date
• Latest AP end date

If the MUID of your office ends in ‘00’, there are other data items which can be included on request. The list is provided on an Excel spreadsheet.

For CT assessing offices ending with numbers other than ‘00’, a set paper listing can be printed. For each case, the list will show

• The reference
• Company name
• Last ‘live’ accounting period (AP) or ‘dormant’ period dates
• Date of liquidation if present
• Company registration and trade classification numbers
• Date last return was received and to which AP it relates
