The Institute For Fiscal Studies (IFS) says that the entire package of tax and benefit changes coming into force by 2014-15 is clearly regressive, including the tax increases put in train by Labour.
The Treasury analysis for the spending review document, which suggests otherwise, excludes a third of the benefit changes planned by the government and does not go up to 2014-15. The changes excluded by this are clearly regressive – they have the greatest effect, relative to income, on people at the lower end of the income scale.
