The table delineates the percentage of gross domestic product (GDP) represented by tax revenue in five distinct countries across four selected years from 1975 to 2005.
Overall, it is evident that the tax revenue as a percentage of GDP exhibited an upward trajectory in all listed countries, with Sweden consistently maintaining the highest figures across the observed period.
In 1975, Sweden recorded a tax revenue of 46% of GDP, significantly higher than the other nations, with the USA at 25.1%, Korea at 15.1%, Japan at 10.5%, and Turkey at 16.4%. By 1985, Sweden’s tax collection experienced a marginal increase to 47%, while the USA and Japan saw slight rises to 25.4% and 16%, respectively. Conversely, Korea recorded a notable increase to 17%, whereas Turkey’s tax revenue declined to 15%. The year 1995 marked a considerable elevation in tax collection for all countries, with Sweden reaching 51%, the USA increasing to 27.1%, and Turkey rising to 24%. Japan and Korea witnessed an uptick as well, with figures of 23% and 26%, respectively.
By 2005, Sweden’s tax collection surged dramatically to 70.1%, reinforcing its position as the country with the highest tax revenue as a percentage of GDP. The USA exhibited a modest increment to 27.4%, while Korea experienced a substantial rise to 30.4%. Japan similarly increased its tax revenue to 32.1%, demonstrating a progressive growth trend. Turkey also showed improvement, stabilizing at 27.4%. Notably, Sweden’s increase from 46% to 70.1% over the three decades starkly contrasts with the more modest increases observed in the other countries, which varied between 0.3% to 10% over the same period.
