I already told you I know nothing about MTD. That includes not knowing if anyone else knows anything. I will tell you, though, that tax filing is not included in the program for any country. As I replied to another user a few months ago:
The tens of thousands (who knows, possibly millions) of businesses in the UK, using hundreds or thousands of different accounting programs, will all face the same issues. Inevitably, some method will appear for submitting data that does not require direct interface from all those accounting programs to a government portal.
