HMRC: how to generate and submit the XML file
Tagged Accounts (HTML) file
- The tagged Accounts (HML file) must be submitted to HMRC through the CT600 form, via a Corporation Tax application.
- The topics below explain how to proceed after generating the HML file and how to attach it to CCH Corporation Tax Return and how to save it if another Corporation Tax application is been used.
Generating the file
After generating the XML file for Financial Statements for Members, the following message appears if there is a Detailed Profit and Loss Account report included in the Accounts.
Detailed Profit and Loss tagging
If you are tagging the Detailed Profit and Loss within the Accounts using the Review and Tag, please click here to follow the steps for this process.
Or if you are tagging the Detailed Profit and Loss within the CCH Corporation Tax (within the Tax Computation) please click here for instructions.
Please note the Detailed Profit and Loss must be tagged on either in the Accounts or in the Computation, but not both. If the DPL is tagged within the Accounts (the HTML file) then any Detailed Profit and Loss tags included in the Corporation Tax will be removed prior to the submission of the form CT600 to HMRC. For more information please refer to this informative Knowledge article 13994
Clearing the errors
Once you know where the Detailed Profit and Loss is tagged and act accordingly then the next step is to make sure that the errors under Exception Report tabs General iXBRL Errors and HMRC Errors are cleared as below. Ignore any error listed under the tab Companies House.
