It seems that the EU will introduce a new VAT directive for small business. One point is that there will be a maximum VAT registration limit of 85,000 Euros (£76,300). Not a problem for any other EU members except the UK, as has already been noted our limit is the highest in Europe and probably the world.
If we have a no deal Brexit then we don't have to worry about this but if there is some sort of deal then this may have to become UK law ( or NI law).
If the registration limit is reduced then more businesses in MTD for VAT....
So AWebbers we have a potential item involving both MTD and Brexit
