@kadach Thank you for the information link. Is there any sort of Companies House checklist available for taking the approval for accounts filing for Micro entity accounts. Could you please breakdown what steps need to be followed?

Hi @sanjay.

You will need to apply for a test account first, as outlined in the guidance provided in the link I shared.
Once your test account is set up, you can begin developing your micro-entity accounts using our Technical Interface Specification (TIS), available here:
Companies_House_TIS_Accounts_Separate__Final__5..7.odt

When you’re ready, you can submit your test files, which will then be reviewed by our team. Once we are satisfied with the quality of your test submissions, we will issue live package credentials for use in the live environment.

Please refer to the TIS document for further details.

Thanks,
KAJ
