Kass, Council Tax is set on the property not on the occupant. the bigger the property the higher band it will be in so the more you pay. Not perfect but we rejected individual contributions under the Poll Tax.
I've some difficulty though believing the figures of 2,200 tenants (in a stock of 12,000 ish) earning these sums with 200 of those on over £100k? Seems a little high imho.
Is there any merit though in the underlying pricnciple which is to allow Coucnils to have autonomy when it comes to setting rent levels? With the reform of the HRA and end to subsidy wouldn't this make sense? It could allow councils to undertake proper business planning and move away from the convergence with higher RSL rents - thereby reducing the HB bill as well?
