Hi, I'm soon to receive a company car through a salary sacrifice scheme operated by a third party, but through my company. When should I report this to HMRC (can I do it prior to receiving the vehicle?) and also what is the best way to do this? I have seen advice that my company will do this, but that I shouldn't rely solely on that, and that it is my responsibility - Happy to accept that, but what is the best method by which to do it? Many thanks in advance.
