There are two main tax allowances available today and these are known as the Nil Rate Band and the Residential Nil Rate Band. The Nil Rate Band is currently £325,000 and is available to everyone. The Residential Nil Rate Band is more complicated and certain criteria must be met in order to qualify for it. If your estate does qualify for the Residential Nil Rate Band, then you are entitled to a further tax allowance of £150,000. This allowance will increase to £175,000 on 6 April 2020.
