According to the OECD, the Swedish tax-to-GDP ratio was 43.9 percent in 2018, fourth highest of the OECD countries and exceeding the average by nearly 10 percentage points.
The tax-to-GDP ratio, measured as total income from taxes and social security contributions divided by the GDP, was 43.9 percent in Sweden in 2018. Compared with the other OECD member states, three countries currently have a higher tax-to-GDP ratio.
Beginning in the 1960s and 1970s, the tax level in Sweden increased sharply and culminated in the late 1980s and early 90s. During the first decade of this century the tax-to-GDP ratio tended to decrease, much due to tax cuts on work income. However, in recent years, that trend has reversed slightly.
