Dear Patrick
Its established law that the enquiry window for SDLT is 9 months and 30 days after the filing date. However, we are constantly asked the same question by clients and solicitors alike and that is, under what circumstances does the period extend to 6 years ? Our response is to say that if HMRC discover any materiel fact which they could not have expected to know or were aware of during the 9 month and 30 day window, then they have a right to go into the 6 year perio. But could you perhapd give us 2 examples of these ‘facts’.
