Having now submitted a second return have to say I’m very pleased with Vatify (although still of the opinion why I need to go through a third party is questionable).
A template form, no different to the original government form, downloaded and saved. Duly filled in, saved as the current required return and then uploaded - return completed.
On the 2nd return advised subscription had expired, thought to myself here we go………how much? But no, had to be renewed, free of charge, just to allow removal of old un-used accounts which does make sense.
Happy to recommend to anyone looking for a free & easy solution to MTD.
