Taxing Wages provides unique information on income tax paid by workers and on social security contributions levied upon employees and their employers in OECD countries. In addition, this annual publication specificies family benefits paid as cash transfers. Amounts of taxes and benefits are detailed programme by programme, for eight household types which differ by income level and household composition. Results reported include the marginal and effective tax burden for one- and two-earner families and total labour costs of employers.

These data on tax burdens and cash benefits are widely used in academic research and in the preparation and evaluation of social and economic policy making.

Taxing Wages 2011 includes a special feature entitled "Trends in personal income tax and social security contribution schedules".

    This annual publication provides details of taxes paid on wages in all thirty-four Member countries of the OECD.Previous editions were published under the title The Tax/Benefit Position of Employees (1996-98 editions) and The Tax/Benefit Position of Production Workers (editions published before 1996). The information contained in the Report covers the personal income tax and social security contributions paid by employees, the social security contributions and payroll taxes paid by their employers and cash benefits received by families. The objective of the Report is to illustrate how personal income taxes, social security contributions and payroll taxes are calculated and to examine how these levies and cash family benefits impact on net household incomes. The results also allow quantitative cross-country comparisons of labour cost levels and of the overall tax and benefit position of single persons and families.

  • Cliquez pour accéder:  Overview

    This Report provides unique information for each of the OECD countries on the income taxes paid by workers, their social security contributions, the family benefits they receive in the form of cash transfers as well as the social security contributions and payroll taxes paid by their employers. Results reported include the marginal and average tax burden for one- and two-earner households, and the implied total labour costs for employers. These data are widely used in academic research and in the formulation and evaluation of social and economic policies. The taxpayer specific detail in this Report enables it to complement the information provided annually in the Revenue Statistics, a publication providing internationally comparative data on tax levels and tax structures in the thirty-four Member countries. The methodology followed in this Report is set out briefly in the introduction section below and described in more detail in .

    Taxes on labour income – including personal income taxes and social security contributions – account for roughly one half of total tax revenue, on average, across OECD countries. High reliance on labour income taxation often results in high tax burdens on workers. Tax burdens can be measured with several alternative indicators, including marginal and average personal tax rates. Marginal personal tax rates, which indicate the tax payable on an additional currency unit of earnings, affect incentives to increase work effort, to follow training or to look for a better-paid job. Average personal tax rates, which indicate the share of gross earnings spent on taxes, may affect incentives to participate in the labour market. Average personal tax rates that increase with income imply that the amount of tax paid is related to an individual’s capacity to pay, and that the tax and benefit system is progressive. Average and marginal personal tax rates on wage income are determined by the interaction of provisions that define the tax base, statutory tax rates, and tax credits that are deducted after the application of tax rates to the tax base. The Taxing Wages series presents these and other key tax burden indicators annually for OECD member countries. To shed light on the underlying differences in average and marginal personal tax rates, this Special Feature takes a close look at statutory personal income tax (PIT) rates, the income thresholds where PIT and employee social security contribution (SSC) rates apply, and other statutory provisions that shape the average and marginal personal tax burden on labour income.

      This Section comments on - and -. These summary tables show results for eight family-types, characterised by different family status (single/married, 0-2 children), economic status (one-/two-earner household) and wage level (33 per cent, 67 per cent, 100 per cent and 167 per cent of annual gross wage earnings of an average worker).

    • Cliquez pour accéder:  Graphical exposition of the 2011 estimated tax burden

      The graphs in this section show the estimated tax burden on labour income in 2011 for gross wage earnings between 50 per cent and 250 per cent of the average wage (AW). For each OECD member country, there are separate graphs for four family types: single taxpayers without children, single parents with two children, one-earner married couples without children and one-earner married couples with two children. The net personal average and marginal tax rates ([the change in] personal income taxes and employee social security contributions net of cash benefits as a percentage of [the change in] gross wage earnings) are included in the graphs that show respectively the average and the marginal tax wedge.The marginal tax wedges in the graphs are calculated in a slightly different manner than the marginal tax rates that are included in the rest of the Taxing Wages publication. In Taxing Wages, marginal rates are usually calculated by increasing gross earnings by one currency unit (except for the spouse in the one-earner married couple whose earnings increase by 1/3 of the average wage). However, the +1 currency unit approach requires the calculation of marginal rates for every single currency unit within the income range included in the graphs. It otherwise would not be correct to draw a line through the different data points because the data for the income levels in between the different points would be missing. In order to reduce the required number of calculations, the marginal rates that are shown in the graphs are calculated by increasing gross earnings by 1 percentage point – each line in the graph therefore consists of 200 data points – instead of 1 currency unit.

      The personal circumstances of taxpayers vary greatly. To identify representative taxpayers and to calculate the amount of their taxes, this Report uses a specific methodology. The focus is on employees. It is assumed that their annual income from employment is equal to a given fraction of the average gross wage earnings of adult, full-time workers in a broad range of industry sectors of each OECD economy. Additional assumptions are made regarding other relevant personal circumstances of these wage earners to enable their tax/benefit position to be determined.  sets out the terminology used in this Report, while provides information on the industry sectors covered.

    • Cliquez pour accéder:  Limitations

      The simple approach of comparing the tax/benefit position of example families avoids many of the conceptual and definitional problems involved in more complex international comparisons of tax burdens and transfer programmes. However, a drawback of this methodology is that the earnings of an average worker will usually occupy a different position in the overall income distribution in different economies, although the earnings relate to workers in similar jobs in various OECD Member countries.

      Each country chapter contains a section describing in a standard format the equations under-pinning the calculations required to derive the amounts of income tax, social security contributions and cash transfers. These algorithms represent in algebraic form the legal provisions described in the chapter and are consistent with the figures shown in the country and comparative tables. This section describes the conventions used in the definition of the equations and how they could be used by those wishing to implement the equations for their own research.
