In the first phase, with a deadline in April, 2019, the following requirements will take effect:
Keeping records digitally - Businesses must now keep all their records digitally. For users of ERP systems this will not have any impact since they already keep their records digitally in these systems.
- As long as the mechanisms are in place subject to HMRC interface specification, output files may be submitted
Submit VAT return electronically using software recognised by HMRC
Should you be part of a Group, you can of course request a delay till October 2019.
The second phase will see the removal of spreadsheet output forms when HMRC will require digitised detail to be submit. This will require actual MTD systems to be installed that convert output files to that mandated by HMRC.
