Share of tax returns from 20.001 up to EUR 30,000

Tax statistics are compiled on the basis of personal tax returns at the place of residence. The income year is the year for which taxes are due. Total taxable net income consists of all net professional income, net real estate income, net movable income and miscellaneous net income. To measure the dispersal of income distribution, tax returns are classified in ascending order of income and divided into 4 equal parts separated by 3 quartiles (Q1: 25 % of the returns have income less than Q1, Q2 = median income: 50 % of returns have income less than Q2, Q3= 75 % of returns have income less than Q3). Tax returns with zero taxable income are not included in the calculations. The indicator reports the difference between the 3 rd and 1st quartile to the median: (Q3-Q1)/Q2. The higher the interquartile coefficient, the higher the degree of income inequality. As it refers to the median value, it makes it possible to compare the dispersion of series with very different median values.
