asked the Chancellor of the Exchequer, following his recent Budget, what gross income would require to be earned in (a) one year's time, (b) two years' time, (c) three years' time, (d) four years' time, (e) five years' time. (f) 10 years' time and (g) 20 years' time by (a) a single male, (b) a married man with no children, (c) a married man with one child, (d) a married man with two children and (e) a married man with three children in order to maintain in real terms the net value after tax of his present annual earnings before tax of(a) £1,500, (b) £2,000, (c) £3,000,(d) £4,000 and (e) £5,000 on the assumption that inflation runs at an annual rate of 20 per cent. and the present rates of tax continue.
The figures are as follows:
For the purposes of the illustrative calculations it has been assumed that all children are under 11 throughout; that the 1975–76 rates of tax and personal allowances remain in force; that family allowances and clawback remain as in 1975–76; and that family allowance is only claimed where it is to the taxpayer's advantage.
asked the Chancellor of the Exchequer what increase in gross income would have been required by (a) a single male, (b) a married man with no children, (c) a married man with one child. (d) a married man with two children and (e) a married man with three children to maintain in real terms the net value of his annual earnings before tax of (a) £1,500, (b) £2,000, (c) £3,000, (d) £4,000 and (e) £5,000 in March 1974.
Assuming that the children are under 11 the figures are as follows:
