How long to create such a system?
With some real experience in bidding for, winning & then implementing Govt. systems,may I suggest that the timescales have been dreadfully under-estimated. Perhaps 1 year to gather the requirements & write a spec. Maybe another year for the competition. Then at least two more years to build it. Then another year at least to fix it!
This adds up to a minimum of 5 years from the point where the Govt. tells HMRC what the new regime looks like. Dates in the range 2023-25 look very likely for such a new system. Knowing what it wants would be a great help, of course
