I have looked at the responses on the issue of Linked Transactions and not that no one has been able to give a definite answer on it. I have a client who is buying five flats from a developer , there are no discounts and the each is prices under the SD threshold. By the simple definition of “linked Transaction” I would assume that it is. HMRC has not been helpful as they have put the ball back in our court.
You seem to be caught by ‘series of transactions’ but given that HMRC say that only you can truly assess this leaves open the possibility in an appropriate case of putting in ‘nil’ returns and enclosing a covering letter setting out the facts in full thus allowing HMRC to challenge you should they deicde to do so. Disclosure here would be vital though.
