The report of the expert group on integrating the tax and social welfare systems, commonly referred to as the TWIG report, was published in 1996. The group's terms of reference covered policy on both taxation and social welfare. The recommendations relating to social welfare measures are primarily a matter for my colleague, the Minister for Social, Community and Family Affairs. The report contained three principal recommendations in relation to tax policy: (1) the gradual elimination of the general income tax exemption limits thereby eliminating marginal relief; (2) the gradual phasing out of the employment and training and health levies over time as resources permit, started by converting the threshold into an allowance; and (3) improved co-ordination of tax and social welfare reforms.
The exemption limit and marginal relief system was identified by the group as a contributory factor in unemployment and poverty traps. Following the changes I announced in the budget of 1999, the first of these recommendations has been largely achieved. The basic personal allowances for the forthcoming tax year, of £4,200 for a single person and £8,400 for a married couple, exceed the general exemption limits of £4,100 for a single person and £8,200 for a married couple. The general exemption limits will now apply only to a small number of married couples on low incomes with three or more children. The numbers on marginal relief have fallen from over 16 per cent of the taxpaying population to just over 2 per cent arising from measures introduced in the last three budgets. Most of the remaining marginal relief cases represent taxpayers aged 65 and over who have a considerably higher exemption limit and where the considerations applied by the TWIG to the general exemption limits would have very limited relevance.
The second recommendation, concerning the levies has been addressed by increasing the threshold for the payment of the levies. However, phasing out of the levies would be costly, and it would not benefit anyone with earnings below the threshold, currently £10,750 per year, though it would be of considerable benefit to those above this threshold. In the 1999 budget, I increased the threshold for payment of the levies to £11,250. I also restructured the levies by abolishing the employment and training levy of 1 per cent and increasing the health levy to 2 per cent, resulting in a reduction of 0.25 per cent in the combined levy charge. The recommendation concerning the levies will be borne in mind in the context of the preparation of future budgets.
