Tonga's government revenue has experienced a significant expansion over the past 27 years, with the latest figure standing at 59.97 percent of GDP, ranking ninth globally. Notably, this represents a peak in government revenue for the country, surpassing the all-time trough of 20.32 percent in 1999. While Tonga's revenue growth has been substantial, it still lags behind that of peer countries such as Norway, which boasts a higher revenue-to-GDP ratio of 61.68 percent. The country's improvement in revenue generation has been a steady trend, with a notable increase in revenue collection over the years. However, in order to sustain this trajectory, Tonga may need to strengthen its tax base, particularly in the non-tax revenue segment, to reduce its reliance on foreign aid and maintain economic stability.
