This week we are looking at the phenomenon of the D4 farmer. Not some wealthy entrepreneur herding cattle in Ballsbridge but wealthy individuals buying up farmland around the country as a wheeze to reduce the inheritance tax bills for their children.

How does the tax break work? What impact will it have on land prices? And is anything being done to change it?

Fiona Reddan of the Irish Times wrote a brilliant article on this last week and she joins host Ciarán Hancock in studio, along with Marty Murphy, who is head of tax at IFAC Ireland, one of the country’s biggest accounting firms with a large number of farmers on its books.
