On the tax side, the total tax-to-GDP ratio stands above the OECD average (37% and 35%, respectively, in 2008) while the progressivity of household taxes is close to the OECD average. However, the progressivity of the personal income tax and social security contributions is steeper at the lower end than at the upper end of the income distribution. Where the solid line falls inside the OECD average, the variable considered stands below the OECD average.
