The tax burden is measured by the ‘tax wedge as a percentage of total labour costs’ – or the total taxes paid by employees and employers, minus family benefits received, divided by the total labour costs of the employer. Taxing Wages also breaks down the tax burden between personal income taxes (PIT), including tax credits, and employee and employer Social Security Contributions (SSC)

Key Taxing Wages results in 2011 included:

• The highest tax wedges for single workers without children who are earning the average wage in their country were observed in Belgium (55.5%), Germany (49.8%) and Hungary and France (49.4%). The lowest tax wedges on the same basis were in Chile (7%), Mexico (16.2%) and New Zealand (15.9%) The average for OECD countries was 35.3%. (See Table 1)
• The average overall tax wedge, for those earning the average wage, increased by 0.3 percentage points between 2010 and 2011. This was largely due to PIT. Of the 26 countries where the tax wedge rose, in 18 the PIT wedge also rose, most notably in Ireland (+3.8 percentage points), Hungary (+2.4 percentage points) and Portugal (+1.4 percentage points). Falls in the overall tax burden were also primarily due to PIT changes - the largest decrease was in New Zealand where the tax wedge fell by 1.1 percentage points due to changes in the income tax rates in 2011.
• The United States was the main exception to the rule. The overall tax wedge fell by 0.9 percentage points in 2011, due to a decrease in employee social security contributions which outweighed an increase in income taxes resulting from the expiry of the temporary “Making Work Pay” non-wastable tax credit.
• The highest tax wedges for one-earner families with two children at the average wage were 42.3% for France, 40.3% for Belgium and 38.6% for Italy. New Zealand had the smallest tax wedge for these families (-1.2%), followed by Chile (7%), Ireland (7.1%) and Switzerland (8.4%). The average for OECD countries was 25.4%. (See Table 2).
• Single people in Hungary faced the biggest increase in the tax burden, but families with children enjoyed the biggest reduction due to a reform of the child tax relief scheme that changed from a tax credit to a more advantageous tax allowance in 2011.

In all OECD countries except Mexico and Chile, the tax wedge for families with children is lower than that for single individuals without children. The differences are particularly large in the Czech Republic, Luxembourg, Belgium, Germany, Hungary, Ireland, New Zealand and Slovenia.
