Residents of Gateshead could be in for a shock if, as expected, all homes are revalued by the government to decide which band they should be in for council tax.
Homes were last valued in 1990 but a government review of council tax, published in March 2007, said properties should be revalued in the near future.
In Wales, revaluation took place 3 years ago and a third of properties went up at least one band, resulting in a council tax bills rising by nearly 20% at a stroke.
With both Labour and the Conservatives committed to keeping council tax, Liberal Democrats have stepped up their campaign for it to be scrapped.
Councillor Yvonne McNicol, who represents Dunston Hill and Whickham East, said, "Council tax is not based on ability to pay. It is unfair and will become far worse when people’s homes are revalued. It should be replaced by a local income tax based on ability to pay, a much fairer system. Revaluation will be crippling for many households in Gateshead."
