† i.e. income tax plus national insurance contributions minus child benefits.

Average manual earnings for 1977–78 are the annual equivalent of the new earnings survey estimate of the average weekly earnings of full-time adult male manual workers in April 1977, updated to May 1977 by the monthly index of average earnings. For 1978–79 the May 1977 figure has been updated by the increase in the new series of the monthly index of average earnings between May 1977 and May 1978—an increase of approximately 12.5 per cent.

The figures for two single people and for the two-wage married couple are based on the assumption that each person earns one-half of the joint income.

In the case of the two-wage married couple it has also been assumed that the wife has elected to pay national insurance contributions at the reduced rate of 2 per cent.

For the married couples with children the amount of child benefits for 1978–79 included in the calculations includes the appropriate proportion of the increase payable from November 1978.

The tax liabilities for 1978–79 are based on the proposals contained in the Finance Bill as approved by the House.

Mr. Knox

asked the Chancellor of the Exchequer how many persons aged under 18 years have been assessed independently of their parents for income tax purposes in each of the past five years.

Mr. Robert Sheldon

I regret that the information is not available.

Mr. Trotter

asked the Chancellor of the Exchequer whether he will give examples of countries which have higher top rates of income tax than Great Britain in respect of (a) earned and (b) unearned incomes.

Mr. Robert Sheldon

Of the countries for which information is available, the following have top rates of income tax on earned income higher than the United Kingdom (83 per cent.):

Percentage rate
Egypt 96.6*
Tanzania 95.0
Sweden 85.0
Portugal 84.0†
Japan 83.7‡
*The rates given are those for 1978 except Egypt (1977).
† Including local income taxes at the Stockholm rate.
‡ Including local income taxes at the usual rates.

I am not aware of any country with a higher top rate of tax on unearned income than the United Kingdom (98 per cent.)

Notes:

1. It has been assumed that the children are aged 4; 4 and 8; 4, 8 and 11; and 4, 8, 11 and 15 respectively.

2. The tax thresholds for January 1978 include the value of tax-free child benefits.

3. As child benefits, since April 1977, are not included as an item of income for the purposes of assessing FIS payable, these too have been included in the January 1978 FIS levels shown above.

4. The figures for supplementary benefit include an addition for rent and rates based on the average amount paid by local authority tenants.
