HMRC enforcer just arrived at our doors and, because he already had my name, asked for me (ain't I lucky).
Without going into too much detail, client company has a substantial CT debt, with no assets and no income, but is expecting a (significantly more substantial) payment early in the new year and will be able to settle.
In May, I spoke to HMRC and made an offer of three comparitively small payments in May, August and September 2016, with full and final balance in February. Of course, the telephone operator couldn't agree this, and referred it to the technical back office for consideration.
Fast forward to today. The enforcer and I compared notes of my earlier conversation, and the only difference between them was that I'd recorded the referral to the technical office. This amused the enforcer enormously, and he ventured that he wished he knew where this technical office is, because he's never encountered it, and nothing had happened following my call until it landed in his desk.
So there we are, from the horses mouth. There is no secret technical back office. It must just be a comforter for the untrained front line staff to think that someone somewhere knows what they are doing.
