Tax-to-GDP Ratio: An Analysis
Governments generate revenue mainly from taxes all over the world. There are various types of taxes, but the most prominent taxes include income, sales, and estate taxes, among others. In the case of income taxes, the state imposes taxes on the income of individuals and businesses. The income taxes imposed on businesses are known as corporate income taxes. In most countries, the majority of the government revenue is added by individual income taxes followed by corporate income taxes. Welfare states usually have high income tax rates as they use the taxpayer’s money for social development in the country. Most of the countries with the highest tax-to-GDP ratio are the countries with the highest income tax rates in the world. Whereas, the countries with the lowest income tax rates in the world don’t have a high tax-to-GDP ratio, excluding Kosovo which has a high tax-to-GDP ratio.
The majority of European countries have high-income tax rates and also the highest tax-to-GDP ratio in the world. In recent years, European countries have made several tax reforms to maintain tax revenue levels while saving households and businesses from high inflation including reducing value-added taxes (VAT) and excise duties, cutting tax rates for low-income households, indexing the income tax to inflation, increasing tax rates for high-income households by raising recurrent taxes on immovable property and net wealth taxes.
According to the OECD Tax Policy Reform 2023 report, many countries reported an increase in tax revenues after the pandemic. In 2021, OECD countries’ average tax-to-GDP ratio rose for a second consecutive year, increasing by 0.6 percentage points from 2020 to 32.1%. This was the largest increase in tax-to-GDP across OECD countries between 1990 and 2021. Out of 36 countries, 24 noted an increase in tax-to-GDP ratio between 2020 and 2021. While, 11 countries suffered a decline in their tax-to-GDP ratio in that period. Norway reported the maximum increase in the tax-to-GDP ratio, followed by Lithuania, Spain, and Germany. Corporate taxes and VATs were the main drivers that led to the increment in revenue. On the contrary, Hungary suffered the largest decline in its tax-to-GDP ratio with a drop of 2.2 percentage points, followed by Canada, Iceland, Mexico, and Türkiye, which also recorded a drop of 1.1 percentage points in their tax-to-GDP ratios between 2020 and 2021.
In recent years, countries have made notable changes to international tax rules which have direct implications for multinational companies. In 2021, more than 130 OECD member jurisdictions agreed to new tax rules. With new international tax rules, large corporations are to pay more taxes in countries where they have their consumer base and pay less taxes in countries where they have headquarters, employees, and operations. The global tax agreement sets a minimum tax rate of 15%, increasing taxes on companies with earnings in low-tax jurisdictions.
