So, on reading that thread, I got a hold of our accounts person and asked for a sit-rep. She came back yesterday with a big grin on her face and told me that she had been talking to our accountants and they were every bit as in-the-dark as we are. "Nobody knows anything!" she told me. "It seems to be like Brexit - one big F-up!" She assured me that the accountants told her that the 'bridging solution' is unusable and HMRC are all lost-at-sea and cannot give the major accountancy firms any sensible answers. So we shall be getting ready for MTD in the same way we are getting ready for Brexit - by doing absolutely nothing!
