5. Effective tax rates on labour income in 2021

The following tables show the effective rax rates on labour income for the eight household types covered by the Taxing Wages models in 2021: single employees, without children, at the average wage (column 2 of the tables) and one-earner married couples, with two children, at the average wage (column 5). Comparisons with columns 1, 3-4 and 6-8 of the tables give corresponding results for the six other household types. Indicators presented in the tables can be compared with the corresponding indicators in Chapter 3, which show the results for 2022.

  • Table 5.1 presents the total tax wedge (calculated as personal income tax plus employee and employer’s social security contributions [SSCs] less cash benefits) by household type as a percentage of labour costs (gross wage plus employers’ SSCs [including payroll taxes]). In the majority of countries, changes in the gap between total labour costs and the corresponding net take-home pay in 2022 compared with 2021 were within plus or minus one percentage point.

  • Table 5.2 shows the combined burden of personal income tax and employee SSCs in the form of personal average tax rates as a percentage of gross wage earnings.

  • Table 5.3 shows the net personal average tax rate, calculated as the total of personal income tax and employee SSCs less the amount of cash benefits as a percentage of gross wage earnings.

  • Table 5.4 presents information on personal income tax due as a percentage of gross wage earnings.

  • Table 5.5 provides information on employee SSCs as a percentage of gross wage earnings.

  • Table 5.6 shows the marginal tax wedge (rate of personal income tax plus employee and employer SSCs and payroll taxes where applicable minus cash benefits) as a percentage of labour costs, when the gross wage earnings of the principal earner rose by 1 currency unit.

  • Table 5.7 presents the marginal rate of personal income tax plus employee SSCs minus cash benefits (the net personal marginal tax rate) by household type and wage level, when the gross wage earnings of the principal earner rose by 1 currency unit.

  • Table 5.8 shows the percentage increase in net income relative to the percentage increase in gross wages when the latter increased by 1 currency unit.

  • Table 5.9 shows the percentage increase in net income relative to the percentage increase in labour costs (i.e. gross wage earnings plus employer social security contributions and payroll taxes) when the latter rises by 1 currency unit. The results shown in Tables 5.8 and 5.9 depend on the marginal and average tax rates

  • Table 5.10 to Table 5.13 report background information on levels of labour costs plus gross and net wages.
