Background Note
6.Currently, where the RPI for the month of September is higher than it was for the previous September, then, unless Parliament otherwise determines, the limit of the NRB increases from the 6 April of the following year by the same percentage as the percentage increase in the RPI.
7.Section 155(1)(b) and (4) of Finance Act 2006 provided for the limit of the NRB to be set at £325,000 for the tax year 2009-10.
8.Section 8 of Finance Act 2010 provided that indexation does not have effect by virtue of any difference between the RPI for the month of September in 2010, 2011, 2012 or 2013 and the previous September, thereby freezing the NRB up to and including 2014-15.
