Note: If you cannot see the return within the Unfulfilled Obligations box, please amend the dates to include the start date of the period you are wishing to submit a VAT return for.
If the return still does not appear, you will need to liaise with HMRC to ensure the VAT return is still outstanding and flagged correctly as an MTD method type of submission. Please continue below for further advice.
To avoid this kind of issue it is recommended that outstanding obligations which are due must be submitted before registering for MTD with HMRC.
Solution:
For this scenario, it would appear that from HMRC's point of systems, the obligation is outstanding as being flagged for the old method type (before MTD), and therefore would not appear in ADT despite amending the date range, as HMRC's API does not see the obligation as an "MTD" type of submission and so cannot pull the obligation through - as the API would ignore it by HMRC's design.
However, as the business tax account is now setup for MTD, the new platform does not have the functionality for submission via that old method.
As of this, there are only 3 possible ways in which the submission can be done, both of which can only be done with HMRC which we cannot assist with or influence.
1. HMRC need to amend / re-flag the July 2019 to June 2021 obligation as the new MTD type rather than the old submission type. If they can amend the obligation to show as outstanding for the new MTD method, this can then be seen by HMRC's API to be pulled into ADT when amending the date range which will allow you to submit in the new method.
2. HMRC need to provide you with a workaround "form" method through another link or document type to fill out and submit to them via (most likely) email.
3. HMRC will need to revert you back to the old submission method (removing your MTD status) so that you are back on the old gateway platform. This would in turn return the functionality to submit the VAT return directly through their site in the old method.
Once submitted, you would then need to re-register for MTD with them.
Note - in this manner, it may be the case that you then continue to submit all the other obligations following in the same old method manner, before re-registering for MTD.
