A tax investigation by Her Majesty's Revenue and Customs is unpleasant, if not downright alarming. When the Taxman comes calling the reaction of even the most rational person, is quite simply - to panic.
BDO has published a book 'The Taxman Always Rings Twice' giving you an overview of what you should and should not do when you hear from the taxman. You can read a copy of this here. Alternatively you can request a hard copy by emailing Daniel Dover.
