Self-employed and buy to let come into MTD in April 2017 if they have income over £10000, I think.
There are certain groups who have to file an SATR whatever their income, and they have their own supplementary pages designed for their circumstances. One such is Ministers of Religion. Some get benefits in kind, eg a manse, but more get occasional income not otherwise classifiable, such as weddings and funerals, and occasional cash gifts outside the normal offering, which would be classed as tips if they drove taxis or cut hair. Their last SATR's will be 2016-2017. In future, how will they report these under MTD?
