INCT - The Implied National Council Tax
When Council Tax was first created the government had a figure called "Council Tax at Standard Spend" which was the figure they assumed would be the average Council Tax at Band D.
This was replaced by the Assumed National Council Tax for 2003/4. One of the problems for the government with these figures is that they make it quite clear that the government is financing local authorities on the assumption that Council Tax will increase beyond inflation.
In 2006/7, however they have stopped declaring the amount. It can, however, be calculated and the INCT (Implied National Council Tax) has gone up by 3.6% for England as a whole and 3.8% for Metropolitan Authorities between 2005/6 and 2006/7. This is, of course, more than inflation.
