MP Murray already stuck in a huge MTD4IT hole and then this boulder arrives on his head:

Its a very rare example of a project with literally *no* return. HMRC's will be negative from a running it/tax loss point of view, given the level of non-compliance will only cut the tax take and force more people outside the system, and for those of them inside it mashing fingers at software, they will tend to overclaim expenses, and so less tax paid. Its "lose, lose, lose" for HMRC.
I think it's even worse than that. I don't know how to find my old posts on here but I summarized this a while ago.
HMRC need a big overhaul of their legacy systems. Selling that to the people who control the purse strings is almost impossible.
So HMRC invented MTD as a way to sneak a major infrastructure overhaul. So far, so good, this is, sadly, the way these things are often done.
However, they didn't plan it at all well. They thought the MTD bit of it would be easy (quarterly updates when disconnected from everything else are easy) but discovered that even quarterly updates come with pain points once you pretend they have a point (hence why we've gone from four quarterly submissions to a cumulative submission four times a year which removes three out of the four pain points... but doesn't actually solve anything!).
Then things really started to go wrong - the project was getting further and further behind the plan and burning more and more money without actually delivering either the "cover plan" or the "real plan". It reached the point where "something must be delivered" and suddenly, all of the tax return became a parallel interface into the legacy system. Obviously I have no insight into the underlying systems but my guess is that MTD (tax return, not quarterly updates) is already "legacy" and "in need of replacement" because the only way to get it over the line was to duplicate the existing interfaces as "new" MTD interfaces.
HMRC will now have more costs to maintain yet another legacy system. I guess they'll force everybody onto the MTD tax return eventually to save face, but it won't have moved them even one inch forward in what they really need to do, just spent a lot of money for no benefit.
