Paris: A second consecutive year of high inflation pushed up labour taxes across the member countries of the Organisation for Economic Co-operation and Development (OECD) in 2023, a new OECD report, Taxing Wages 2024, revealed today.
According to the report, effective tax rates on labour incomes rose in most OECD countries with the post-tax income of single workers earning the average wage declining in 21 out of 38 OECD countries.
In a majority of countries, the increase in labour taxation was primarily driven by increases in personal income tax. While real wages declined in 18 OECD countries, nominal wages increased in 37 of 38 OECD countries, as inflation remained above historic levels. In the absence of automatic indexation of tax systems in many OECD countries, high inflation tends to increase workers’ tax liabilities by pushing them into higher tax brackets and eroding the value of the tax reliefs and cash benefits they receive.
The new OECD analysis focuses on a cross-country comparison of the labour tax wedge – defined as total taxes on labour paid by both employees and employers, minus family benefits, as a percentage of labour costs. It looks at eight different household types, varying by income level and household composition.
For a single worker earning the average wage, the average tax wedge across OECD countries was 34.8%, ranging from 53% in Belgium to 0% in Colombia in 2023. The average tax wedge for this household type increased by 0.13 percentage points from 2022, marking an increase for the second consecutive year.
This year’s edition of Taxing Wages includes a special feature that examines how the tax wedge differs between first and second earners. Specifically, the report analyses the tax rates on second earners in married couples, more than 75% of whom are women in almost all OECD countries. It finds that second earners face higher effective tax rates than single workers when they take up work at the same wage level in the majority of OECD countries, although the difference has narrowed in recent years.
On average in the OECD, a second earner in a couple without children who takes up work at 67% of the average wage faces a tax wedge of 34.0%, versus 31.0% for a single worker earning 67% of the average wage. Fiscal disincentives for second earners are larger in countries where taxation occurs at the household level or in countries with individual-level taxation where tax reliefs are considered at the household level.
Taxing Wages 2024 enables cross-country comparisons of labour costs and the overall tax and benefit position across the OECD. It analyses income tax paid by employees, cash benefits received by in-work families and the associated social security contributions and payroll taxes made by employees and employers, which are key factors affecting the workforce participation and hiring decisions of individuals and businesses respectively.
