The table compares tax revenue as a percentage of GDP across five nations, namely Sweden, the USA, Korea, Japan, and Turkey, from 1975 to 2005.
Overall, the amount of tax collected in all countries increased throughout the period. Notably, the figure for Sweden consistently recorded the largest rates, while that for Japan remained the lowest in most years.
In 1975, the level of taxation in Sweden stood at 46%. In the following years, this number surged to reach a peak of 70.1% in 2005. Similarly, tax revenue in Japan and the USA underwent consistent growth. While the former figure increased sharply, from 15% in 1975 to 32.1% in 2005, the latter figure rose more slowly, from 25.1% to 27.4% during the same period.
By contrast, tax revenue in Korea experienced a fluctuating pattern, ranging from 15.1% to 27.3%. On the other hand, tax collection accounted for 16.4% of Turkey’s GDP in 1975. Although there was a modest drop to 15% in 1985, this number then increased steadily, reaching 27.4% by the end of the period
