As mandatory quarterly reporting under Making Tax Digital (MTD) kicks in from taxpayers with non-PAYE qualifying income over the £50,000 threshold, only 185,000 individuals have signed up for the new system.

HMRC confirmed there is a steady flow of new registrants every day with around 15,000 taxpayers a day signing up but this leaves 683,000 landlords, sole traders and self employed still waiting to make the final move.
