The OECD’s latest Revenue Statistics 2024 report shows that the average tax-to-GDP ratio across OECD member countries remained stable at 33.9% in 2023, down just 0.1 percentage points from the previous year. Although this is the second straight year of slight decline, the figure remains above its pre-pandemic level of 33.4% in 2019.
As the OECD notes, “The average level of tax revenues among OECD countries was largely unchanged in 2023 as governments sought to ease cost-of-living pressures amid growing spending challenges related to climate change and ageing populations.”
Tax burdens continue to differ markedly, ranging from 17.7% of GDP in Mexico to 43.8% in France. The gap between the highest and lowest ratios has narrowed in recent years, standing at 26.1 percentage points in 2023—“the smallest difference since at least 2000,” according to the OECD.
