The tax rates faced by workers are ticking up, according to new data from the Organization for Economic Co-operation and Development (OECD).

In a new report, it says that, across the OECD, the average tax and social security burden on employment incomes increased by 0.1 of a percentage point to 35.6% in 2012 (the tax burden is measured as the total taxes paid by employees and employers, minus family benefits received, divided by the total labour costs of the employer.). The rates increased in 19 out of 34 countries, fell in 14, and remained unchanged in one country.

The average worker in Canada faced a tax burden on labour income of 30.8%, ranking 25th out of the 34 OECD countries (in decreasing order). The tax burden for the average single worker in Canada decreased by 2.4 percentage points between 2000 and 2012, but between 2009 and 2012, there was an increase of 0.2 percentage points, it reports. For the OECD overall, rates decreased by 1.1 percentage points from 36.7% to 35.6% between 2000 and 2012; and, increased by 0.6 percentage points between 2009 and 2012.

The OECD also reports that the tax burden for a one-earner couple with two children in Canada decreased by 5.7 percentage points from 23.9% to 18.2% between 2000 and 2012; between 2009 and 2012, there was an increase of 1.2 percentage points. Overall, rates decreased by 1.6 percentage points from 27.7% to 26.1% between 2000 and 2012. and increased by 1.1 percentage points between 2009 and 2012.

The report says that the increases were largest in the Netherlands, Poland and the Slovak Republic (mainly due to increased rates and other changes to employers’ social security contributions) as well as Spain and Australia (due to higher statutory income tax rates).

The highest average tax burdens for single workers earning the average wage in their country were observed in Belgium (56.0%), France (50.2%), Germany (49.7%) and Hungary (49.4%). The lowest were in Chile (7%), New Zealand (16.4%) and Mexico (19.0%).

The highest burdens for one-earner/two children families at the average wage were in France (43.1%), Greece (43.0%), Belgium (41.4%) and Italy (38.3%). New Zealand had the smallest burden for these families (0.6%), followed by Ireland (6.4%), Chile (7%), and Switzerland (9.5%).
