The revenue model of the government is based on the tax system. The structure of a country’s tax code is a major player that determines its economic performance. The collection of taxes and fees is an underlying responsibility of the government to generate public revenues that help in financing infrastructure, human capital, and services for citizens and businesses. Individuals whose income falls under the tax brackets have to pay income taxes to the state. Countries with poor tax systems can disrupt their domestic economy and impact economic decision-making. Many countries have recognized the significance of tax systems and have reformed their tax codes. 

Global Taxation: An Analysis

Over the past decades, marginal tax rates on individual and corporate incomes have dropped significantly across the Organisation for Economic Co-operation and Development (OECD) nations. The United States continues to reduce its personal income tax rates and corporate income tax rates. In 2024, 34 US states will go through significant tax changes. 16 states with income tax cuts in 2024 have previously been covered. Other countries such as France have reduced their corporate income tax rates by several percentage points, as per the Tax Foundation. Portugal has made improvements to its corporate tax base, while Belgium has made its corporate tax base less competitive. Chile, the US, and the UK are phasing out temporary improvements to their corporate tax bases. 

The global economies have gone through a massive shift following the COVID-19 pandemic. Inflation, high interest rates, and fiscal pressures have impacted the earnings of individuals globally. This has affected the tax collection for countries. For instance, the total revenue of the US government increased from $4.19 trillion in 2015 to $4.44 trillion in 2023. This is a slight increase and if we consider the revenue increase against inflation, the total revenue has decreased over the last seven years. 

A competitive tax code is important for a thriving economy and a competitive tax code helps in keeping the marginal tax rates low. In today’s globalized world, individuals and corporations opt for places where the rate of return is highest and they have to pay the least taxes. Countries such as Saudi Arabia, Qatar, and the United Arab Emirates are considered some of the top places for investment with the lowest income taxes. If a country’s tax rate is too high, it will repel investment elsewhere which could lead to slower economic growth. 

According to the Tax Foundation’s International Tax Competitiveness Index, Estonia attained the top spot in 2023 among the OECD countries for having the best tax code for a straight tenth year. The ranking of the International Tax Competitiveness Index is based on several other taxes including property taxes and cross-border taxes, in addition to personal and corporate income taxes. Estonia is also one of the safest low tax countries to live in for the US citizens. Latvia has the second most competitive tax system and follows an Estonian system for corporate taxation. New Zealand, Switzerland, Czech Republic, Luxembourg, and Turkey, are the next best countries with the most competitive tax systems, having a competitive tax score of 88.5, 86.1, 84.7, 81.2, 78.9, and 78.6, respectively. Estonia, Switzerland, Czech Republic, Luxembourg, and Turkey are some of the top countries with the lowest income tax rates in Europe. Whereas, Finland, Denmark, Austria, Sweden, Aruba, and Belgium are the European countries with the highest income tax rates in the world.

Our Methodology

To list countries with the lowest income tax rates in the world, we have used three metrics including personal income tax rate, corporate income tax rate, and GDP per capita (PPP). The key metric is the personal income tax rate based on which we have ranked the countries with the lowest income tax rates in the world. For the countries with similar personal income tax rates, we have ranked them based on their corporate income tax rate. If both the metrics of personal and corporate income tax rates are the same, then we have used the country’s GDP per capita, as of 2024, to rank them – the country with higher GDP per capita is ranked higher on the list. We have taken the personal income tax rate and corporate income tax rate data from the PwC and Trading Economics database, which are updated as of December 2023 or January 2024. The GDP per capita (PPP) data is taken from the International Monetary Fund’s (IMF) database. Bermuda and Cayman Islands did not have GDP per capita data available on the IMF database, therefore, we have taken their GDP per capita from the World Bank.
