Personal income and property
The statistics on personal income and property are based upon data from the ordinary tax assessment for personal taxpayers and the special taxation of seamen. Since 1989 seamen have been included in the regular taxation system.
The statistics are specified according to income year. The data on assessed income and assessed property comprise only income and property on which tax has been levied. Since 1967 the statistics have contained information on occupational income (pensionable income). This sort of income has been registered since 1968, even if the amount is below the limit for prescription of membership contribution to the National Pension Fund. Since 1979 such income has been registered regardless of both upper and lower limit for membership contribution. Since 1979 pensionable income for persons under 17 years or over 69 years has also been registered.
Average net income shows a higher growth in the seventies than in the eighties when measured in fixed value. When taxation comes into question, average figures show that assessed taxes exceeded the 1985 level in the years 1979-1980 and each of the years after 1985 with 1987 as the maximum.
As far as occupational income is concerned, the figures show a growing share of the population with such income. This development is mainly due to an increasing number of women in the workforce. The equalisation between the sexes is reflected both in average occupational income and in the distribution of occupational income.
According to the tax return accounts, income from pensions and capital interest account for a growing share of gross income. Among income deductions, interest paid had the highest growth.
