The grievance as to distribution has been modified, if not removed, by the great development of (1) the income-tax, (2) the "death" or inheritance duties. Beginning at the rate of 7d. per pound (1842-1854), the income-tax was raised to 1s. 4d. for the Crimean War, and then continued at varying rates; reduced to 2d. in 1874, it rose to 5d., then in 1894 to 8d., and by 1909 appeared to be fixed as a minimum at 1s., or 5% on income from property. The yield per penny on the £ has risen almost uninterruptedly. From £710,000 in 1842, it now exceeds £2,800,000, though the exemptions and abatements are much more extensive. In fact, all incomes of £3 per week are absolutely free (£160 per annum is the precise exemption limit), and an income of £400 derived from personal exertion pays less than 5½d. per pound, or 2¼%. The great productiveness of the tax is equally remarkable. From £5,600,000 in 1843 (with a rate of 7d.) the return rose to £32,380,000 in 1907-1908, having been at the maximum of £38,800,000 in 1902-1903, with a tax rate of 6¼%. The income-tax thus supplies about one-fifth of the total revenue, or one-fourth of that obtained by taxation. Several fundamental questions of finance are connected with the taxation of income and have been dealt with by English practice. Small incomes claim lenient treatment; and, as mentioned above, this leniency means in England complete freedom. Again, earned incomes appear to represent lower ability to pay than unearned ones. Long refused on practical grounds (as by Gladstone and Lowe), the concession of an abatement of 25% on earned incomes of £2000 and under was granted in 1907. The question whether savings should be exempt from taxation as income has (with the exception of life insurance premiums) been decided in the negative. Allowances for depreciation and cost of repairs are partially recognized. Far more important than these special problems is the general one of increased tax rates on large incomes. Up to 1908-1909 the tax above the abatement limit of £700 remained strictly proportional; but opinion showed a decided tendency in favour of extra rates or a "super tax" on incomes above an assigned amount (e.g. £5000), and this was included in the budget of 1909-1910 (see INCOME-TAX).
