The Residence Nil-Rate Band (RNRB) was introduced as part of a broader effort by the UK government to alleviate the impact of Inheritance Tax (IHT) on middle-class families, particularly those whose primary asset was the family home. It was first announced in the 2015 Summer Budget by then-Chancellor, George Osborne. The government recognized that rising property prices were pushing more estates over the IHT threshold, and many families were being forced to pay large tax bills on modest estates, especially when passing down family homes to children or grandchildren.
